#Predicting prostate cancer: Nanotechnology shows promise for more accurate prostate cancer screening and prognosis Abstract:
A Northwestern University-led study in the emerging field of nanocytology could one day help men make better decisions about
whether or not to undergo aggressive prostate cancer treatments. Technology developed by Northwestern University researchers may help solve that quandary by allowing physicians to identify which nascent cancers are likely to escalate into potentially life-threatening malignancies and
which ones will remain"indolent,"or nonaggressive. The prostate specific-antigen antigen (PSA) test was recommended once the screening tool for detecting prostate cancer,
but there is now disagreement over the use of this test because it can't predict which men with elevated PSA levels will actually develop an aggressive form of the disease."
"If we can predict a prognosis with our technology, then men will know if their cancer is dangerous
and if they should seek treatment, "said Vadim Backman, senior author of the study.""Right now there is no perfect tool to predict a prognosis for prostate cancer.
Our research is preliminary, but it is promising and proves that the concept works.""Backman is a professor of biomedical engineering at Northwestern's Mccormick School of engineering and Applied science.
The study, which includes researchers from Northwestern, Northshore University Healthsystem (Northshore) and Boston Medical center, was published online in PLOS ONE.
Backman has been studying cell abnormalities at the nanoscale in many different types of cancers, using an optical technique he pioneered called partial wave spectroscopic (PWS) microscopy.
PWS can detect cell features as small as 20 nanometers, uncovering differences in cells that
otherwise appear normal using standard microscopy techniques. His previous studies have shown promise that PWS can assess the risk of lung
colon and pancreatic cancers in humans. This sort of prescreening can lead to earlier, lifesaving interventions. This is the first study to use PWS to predict a cancer prognosis, the likely course of the disease.
Prostate cancer is the second-leading cause of cancer deaths in American men, but doctors also say it is often overdiagnosed and overtreated.
By age 80, more than 50 percent of men will develop prostate cancer but not all will have the aggressive,
deadly form of the disease. However, because their prognosis is unknown, many opt for aggressive treatments that have side effects that cause urinary,
bowel and erectile dysfunctions and more.""The goal is to find specific biomarkers of aggressive cancers,
"said Charles Brendler, MD, Co-Director of the John and Carol Walter Center for Urological Health & Program for Personalized Cancer Care at Northshore and author of the study."
"These biomarkers will allow us to individualize our treatment recommendations and improve patient outcomes.""To be able to give a patient a prognosis,
not just identification of risk of tumors, would be said a major advancement Dr. Hemant K. Roy professor of medicine and Chief of gastroenterology at Boston Medical center and an author of the study."
"This approach may allow tailoring of clinical decisions regarding management of patients with prostate cancer,
thus maximizing the benefit and minimizing the harms of therapy, "Roy said. In this study, researchers analyzed prostate tissue biopsies from two cohorts of prostate cancer patients.
The first cohort included eight men with non-progressing cancer and 10 with progressing cancer.
The PWS operator was blinded to the clinical status of the patients. The second cohort was comprised of 10 progressors and 10 non-progressors in
which the PWS investigators were blinded to the entire group. There was a profound increase in nano-architectural disorder in the progressors as compared to the non-progressors.
This assessment may represent a powerful biomarker to predict cancer progression for men with early-stage prostate cancer."
"This study has high quality data because it was done in a blinded fashion, "Backman said.""Given that even in the unblinded dataset the investigator responsible for data acquisition was unaware of the clinical status,
there is no possibility of bias.""More studies are planned to further this research. Backman also hopes to use similar techniques to predict cancer progression in ovarian, breast and esophageal cancers.##

#Drexel Univ. materials research could unlock potential of lithium-sulfur batteries Drexel researchers, along with colleagues at Aix-Marseille University in France, have discovered a high performance cathode material with great promise for use in next generation lithium-sulfur batteries that could one day be used to power
mobile devices and electric cars. Lithium-sulfur batteries have recently become one of the hottest topics in the field of energy storage devices due to their high energy density
--which is about four times higher than that of lithium-ion batteries currently used in mobile devices.
One of the major challenges for the practical application of lithium-sulfur batteries is to find cathode materials that demonstrate long-term stability.
An international research collaboration led by Drexel's Yury Gogotsi, Phd, Distinguished University and Trustee Chair professor in the College of Engineering and director of its Nanomaterials Research Group, has created a two-dimensional carbon/sulfur nanolaminate that could be a viable candidate for use as a lithium-sulfur
cathode. In a paper they recently published in the chemistry journal Angewandte Chemie, Gogotsi, along with his colleagues at Aix-Marseille University explain their process for extracting the nanolaminate from a three-dimensional material called a Ti2sc MAX phase.
Their paper was selected as a VIP article and will be featured on the journal cover. The MAX phase
which is one of a family of layered ceramics discovered two decades ago by Michel Barsoum, Phd,
Distinguished professor in Drexel's Department of Materials science & Engineering, has been used as the basis for much of Drexel's materials research intended to find better materials for batteries.
The researchers found that carbon/sulfur nanolaminates have covalent bonding between carbon and sulfur and an extremely uniform distribution of sulfur between the atomically thin carbon layers.
This structure is key to their potential for being used as electrode materials for lithium-sulfur batteries.
Currently, sulfur infiltrated carbon nanomaterials have demonstrated to be the most promising cathode materials for Li-S batteries.
In these materials the uniform distribution of sulfur in carbon matrix and the strong interaction between carbon and sulfur are two important factors that affect the performance.
The carbon/sulfur nanolaminates synthesized by Gogotsi's group demonstrate the same uniformity as the infiltrated carbon nanomaterials,
but the sulfur in the nanolaminates is deposited uniformly in the carbon matrix as atomically thin layers
and a strong covalent bonding between carbon and sulfur is observed. This may have a significant impact on increasing the life-span of next generation batteries."
"We have enough evidence to show that that the electrochemical etching can be a powerful method to selectively extract the'M'elements from the MAX phases,
to produce a variety of'AX'layered structures, that cannot be made otherwise,"said Meng-Qiang Zhao,
Gogotsi's postdoctoral associate and the lead author on the paper. This is a significant discovery,
because there are more than 70 MAX phases in known existence. Gogotsi estimates that odds are with the MAX phase's new"AX"progeny becoming the materials that find use in next-generation electrical storage devices."
"It is not difficult to foresee that the'AX'structures represent a new family of nanostructured materials, much
of which will probably be said 2d, "Gogotsi.""The various'A'and'X'combinations already known make the'AX'structures highly attractive for a number of potential applications,
such as electrical energy storage and catalysis."#This work was supported by the U s. Department of energy, Office of Basic energy Science e
#EEJA and Tokyo U Achieve Simultaneous Formation of Contact Electrodes for P-type and N-type Organic semiconductor Crystals Using the Plating Method Tanaka Holdings, Co.,Ltd.
Head office: Chiyoda-ku, Tokyo; President & CEO: Akira Tanae) announced today that Electroplating Engineers of Japan, Ltd.
Plant and Office: Hiratsuka-shi, Kanagawa; President and CEO: Koichiro Tanaka; EEJA), which operates the Tanaka Precious metals Group's plating business,
together with Professor Junichi Takeya of the University of Tokyo's Graduate school of Frontier Sciences, has achieved the world's first success in the development of technology for the simultaneous formation of contact electrodes for p-type and n-type*1
Organic semiconductor Field Effect Transistors("OFET, "hereafter) using an electroless plating process. By using an electroless gold plating process with silver nanoparticles as a catalyst for an organic semiconductor,
this technology enables the formation in the atmosphere of top contact-type OFET (figure 1)* 2 contact electrodes without the use of a vacuum environment,
which requires large-scale equipment. As opposed to metallic ink, which has the same atmospheric contact formation,
this technology realizes the formation of a high-performance OFET as there is little damage to the organic semiconductor,
and the performance of the high-mobility*3 organic semiconductor is affected not. Also, due to the emergence of high-performance n-type semiconductor materials in recent years, more advanced organic electronic devices can now be formed at a low-cost thanks to the simultaneous formation of contact electrodes for p-type and n-type
OFET mixed circuits, for which development is speeding up. For p-type organic semiconductors the contact resistance of the contact electrodes using this technology is 0. 1kiloohm-cm or less,
which is the lowest value currently on record in terms of the contact resistance of organic semiconductor contact electrodes formed in the atmosphere.
The atmospheric formation of a high-performance OFET (Figure 2) with low-contact resistance electrodes and high-mobility that are among the top levels in the world is achieved by combining the merits of this technology with those of high-performance
coating-type organic semiconductors developed by Professor Takeya which can be formed atmospherically. This result enables the atmospheric formation of organic electronic devices with high-speed drives
and it enables the production of high functionality electronic devices using printed electronics*4. This technology is a process for the formation of contact electrodes with a gold-silver hybrid structure,
which is achieved by applying a silver catalyst solution for plating that includes silver nanoparticles to an organic semiconductor crystal, after
which a gold coating is applied to the substrate by immersing it in an electroless gold plating solution
so that the gaps between the silver grains are filled with gold. This enables the single-process formation of low-contact resistance contact electrodes for p-type organic semiconductors
which facilitate a charge injection from gold, and n-type organic semiconductors, which facilitate a charge injection from silver (Figure 3). EEJA will announce the research findings relating to this technology at the 62nd Jpan Society of Applied Physics Spring Meeting,
to be held between March 11 and March 14 at Tokai University, Shonan Campus (Hiratsuka-shi, Kanagawa). Background to this technology OFET is a transistor that uses an organic semiconductor,
which means that-among other characteristics unique to organic materials-it can be formed at low-temperatures,
is lightweight and is flexible. The high-performance of organic semiconductor materials has progressed rapidly in recent years,
and materials are being developed with double-digit increases over the figure that was thought to be the limit for the mobility of organic semiconductors.
The pioneering findings of Professor Takeya's research group make possible the atmospheric formation of high-mobility organic semiconductors,
which is expected to increase the fields of use for organic semiconductors. While there are several methods for the formation of OFET contact electrodes
they all suffer from such issues as requiring a vacuum environment and causing damage to organic semiconductors.
For example, thin film electrodes can be formed uniformly using the vacuum deposition method, but the equipment used to create a vacuum environment is incredibly expensive,
and the loss of materials is huge. Also, while electrode formation in the atmosphere is possible using metallic ink and metallic paste,
it also requires the inclusion of organic solvents, high-temperature sintering, and hardening by means of ultraviolet rays,
which damages the organic semiconductor, and does not achieve sufficient results as a transistor. This is why
in September 2014, EEJA together with Professor Takeya's research group jointly developed plating-process contact electrode formation technology for p-type organic semiconductors.
In order to stably form electrodes for organic semiconductor crystals, EEJA developed new gold nanoparticles as an electroless plating catalyst.
The contact resistance of the contact electrodes formed using this technology is 0. 7kiloohm-cm,
which is a remarkably low contact resistance for atmospheric formation contact electrodes. Also, Professor Takeya's research group developed a coating-type organic semiconductor that could be formed in a short time in the atmosphere with a large-surface thin film with uniform crystal orientation
and a mobility (which is the deciding factor in the performance of semiconductors) that greatly surpasses that of conventional organic semiconductors at 10cm2/Vs or more.
Contributing to the development of new devices with OFET application-the development for the future Because OFET has the characteristics of being printable, lightweight and flexible,
we anticipate such device developments as flexible displays and disposable RFID (automatic wireless identification) tags. Currently, development is mainly progressing for devices that use p-type organic semiconductors,
but the development of all-flexible displays and wearable computers, which require advanced circuitry and bendable driver ICS,
also requires p-type and n-type OFET mixed circuitry and both OFETS must operate at high speeds.
This jointly developed technology contributes to technical innovation in connection to organic electronic devices. EEJA will continue to find further solutions for utilization in organic electronic devices.*
*1 p-type organic semiconductors and n-type organic semiconductors Organic compounds crystalized with uniform crystal orientation acquire the characteristics of a semiconductor.
By injecting a positive charge, the electrified object is referred to as a p-(positive) type organic semiconductor. By injecting a negative charge,
the electrified object is referred to as an n-(negative) type organic semiconductor. The metal that is easier to be injected with a charge varies depending on
whether it is a p-type or n-type.**2 Top contact-type OFET This is an organic transistor where the contact electrodes are located on the semiconductor crystal.
This structure enables a drive with a higher speed than that of OFETS with other structures.
However, because the electrodes are formed after forming the organic semiconductor crystal, the organic semiconductor is damaged easily, and contact electrodes are difficult to form.*
*3 Mobility This signifies the ease of movement for the charge within the semiconductor. Electronic devices that carry out complex processes require a higher mobility.
Until a few years ago, the mobility of organic semiconductors was generally about 0. 1cm2/Vs, but materials have been developed in recent years with a mobility of 10cm2/Vs or more.*
*4 Printed electronics This is a technology for the atmospheric formation of electronic circuits and devices on substrates using printing technology and so on.##

#Nanotechnology Raises Possibility to Produce Strongest Commercial Pure Aluminum Alloy Iranian researchers from Amirkabir University of Technology in association with Spanish researchers presented a new process to obtain highly strong
ultrafine grained and nanostructured materials. The process was designed in a way that it enabled the researchers to produce nanocomposite and nanostructured metal at the same time.
Results of the research will be used in aerospace industries, automobile manufacturing and all industries related to aluminum and light metals.
Novel technologies take step towards the production of lighter but stronger alloys to save energy.
There are three important limitations in the majority of severe plastic deformation (SPD) processes. In these processes
expensive forming devices are required with high load capacity. Low amount of production and limitations in the size of the product are among the other problems of these processes.
The impossibility of production of composite in plastic deformation methods is among the other limitations in these processes.
Due to the abovementioned limitations and the need for the creation of new methods, the researchers proposed a new severe plastic deformation method under the title annular pressure buildup (APB.
In this research, commercial 1050 pure aluminum was used as the base alloy while silicon carbide nanoparticles were used as the strengthening agent.
Results of the research showed that aluminum and its alloys produced through APB process without the creation of any crack
or layers are final consistent products with great quality. According to the researchers, the simultaneous combination of ultrafine grained structure with average particle size of 280 nm
and silicon carbide nanoparticles with aver particle size of 55 nm as strengthening agents results in the production of aluminum-based nanocomposite with a strength of 284 MPA.
This value is reported the highest value for the strength of commercial pure aluminum across the world.
Results of the research have been published in Scripta Materialia vol. 100, issue 1, 2015, pp. 40-43 3
#New technology may double radio frequency data capacity: Columbia engineers invent nanoscale IC that enables simultaneous transmission
and reception at the same frequency in a wireless radio A team of Columbia Engineering researchers has invented a technology--full-duplex radio integrated circuits (ICS)--that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception
at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times or at the same time but at different frequencies.
The Columbia team, led by Electrical engineering Associate professor Harish Krishnaswamy, is the first to demonstrate an IC that can accomplish this.
The researchers presented their work at the International Solid-state Circuits Conference (ISSCC) in San francisco on February 25."
"This is a game-changer, "says Krishnaswamy.""By leveraging our new technology, networks can effectively double the frequency spectrum resources available for devices like smartphones and tablets."
"In the era of Big data, the current frequency spectrum crisis is one of the biggest challenges researchers are grappling with
and it is clear that today's wireless networks will not be able to support tomorrow's data deluge.
Today's standards, such as 4G LTE, already support 40 different frequency bands, and there is no space left at radio frequencies for future expansion.
At the same time, the grand challenge of the next-generation 5g network is to increase the data capacity by 1, 000 times.
So the ability to have a transmitter and receiver reuse the same frequency has the potential to immediately double the data capacity of today's networks.
Krishnaswamy notes that other research groups and startup companies have demonstrated the theoretical feasibility of simultaneous transmission and reception at the same frequency,
but no one has yet been able to build tiny nanoscale ICS with this capability.""Our work is the first to demonstrate an IC that can receive
and transmit simultaneously,"he says.""Doing this in an IC is critical if we are to have widespread impact
and bring this functionality to handheld devices such as cellular handsets, mobile devices such as tablets for Wifi,
and in cellular and Wifi base stations to support full duplex communications.""The biggest challenge the team faced with full duplex was canceling the transmitter's echo.
Imagine that you are trying to listen to someone whisper from far away while at the same time someone else is yelling
while standing next to you. If you can cancel the echo of the person yelling,
you can hear the other person whispering.""If everyone could do this, everyone could talk
and listen at the same time, and conversations would take half the amount of time and resources as they take right now,
"explains Jin Zhou, Krishnaswamy's Phd student and the paper's lead author.""Transmitter echo or'self-interference'cancellation has been a fundamental challenge,
especially when performed in a tiny nanoscale IC, and we have found a way to solve that challenge."
"Krishnaswamy and Zhou plan next to test a number of full-duplex nodes to understand what the gains are at the network level."
"We are working closely with Electrical engineering Associate professor Gil Zussman's group, who are network theory experts here at Columbia Engineering,
"Krishnaswamy adds.""It will be very exciting if we are indeed able to deliver the promised performance gains."#

#Engineers create chameleon-like artificial'skin'that shifts color on demand Abstract: Borrowing a trick from nature,
engineers from the University of California at Berkeley have created an incredibly thin, chameleon-like material that can be made to change color--on demand--by simply applying a minute amount of force.
This new material-of-many-colors offers intriguing possibilities for an entirely new class of display technologies, color-shifting camouflage,
and sensors that can detect otherwise imperceptible defects in buildings, bridges, and aircraft.""This is the first time anybody has made a flexible chameleon-like skin that can change color simply by flexing it,
"said Connie J. Chang-Hasnain, a member of the Berkeley team and co-author on a paper published today in Optica,
The Optical Society's (OSA) new high-impact journal. By precisely etching tiny features--smaller than a wavelength of light--onto a silicon film one thousand times thinner than a human hair, the researchers were able to select the range of colors the material would reflect,
depending on how it was flexed and bent. A Material that's a Horse of a Different Colorthe colors we typically see in paints
fabrics, and other natural substances occur when white, broad spectrum light strikes their surfaces. The unique chemical composition of each surface then absorbs various bands,
or wavelengths of light. Those that aren't absorbed are reflected back, with shorter wavelengths giving objects a blue hue and longer wavelengths appearing redder and the entire rainbow of possible combinations in between.
Changing the color of a surface, such as the leaves on the trees in autumn, requires a change in chemical make-up.
Recently, engineers and scientists have been exploring another approach, one that would create designer colors without the use of chemical dyes and pigments.
Rather than controlling the chemical composition of a material it's possible to control the surface features on the tiniest of scales
so they interact and reflect particular wavelengths of light. This type of"structural color"is much less common in nature,
but is used by some butterflies and beetles to create a particularly iridescent display of color.
Controlling light with structures rather than traditional optics is not new. In astronomy, for example, evenly spaced slits known as diffraction gratings are used routinely to direct light
and spread it into its component colors. Efforts to control color with this technique, however, have proved impractical
because the optical losses are simply too great. The authors of the Optica paper applied a similar principle
though with a radically different design, to achieve the color control they were looking for.
In place of slits cut into a film they instead etched rows of ridges onto a single, thin layer of silicon.
Rather than spreading the light into a complete rainbow, however, these ridges--or bars--reflect a very specific wavelength of light.
By"tuning"the spaces between the bars, it's possible to select the specific color to be reflected.
Unlike the slits in a diffraction grating, however, the silicon bars were extremely efficient and readily reflected the frequency of light they were tuned to.
The Berkeley researchers were able to overcome both these hurdles by forming their grating bars using a semiconductor layer of silicon approximately 120 nanometers thick.
Its flexibility was imparted by embedding the silicon bars into a flexible layer of silicone. As the silicone was bent
or flexed, the period of the grating spacings responded in kind. The semiconductor material also allowed the team to create a skin that was incredibly thin, perfectly flat,
and easy to manufacture with the desired surface properties. This produces materials that reflect precise and very pure colors
Their initial design, subjected to a change in period of a mere 25 nanometers, created brilliant colors that could be shifted from green to yellow,
orange, and red-across a 39-nanometer range of wavelengths. Future designs, the researchers believe,
"For consumers, this chameleon material could be used in a new class of display technologies, adding brilliant color presentations to outdoor entertainment venues.
It also may be possible to create an active camouflage on the exterior of vehicles that would change color to better match the surrounding environment.
More day-to-day applications could include sensors that would change color to indicate that structural fatigue was stressing critical components on bridges, buildings,
