#Nanotechnology Helps Increasing Rate of Digital data Processing, Storage Iranian researchers proposed a new method based on nanotechnology to increase the rate of digital data processing and storage.
Quantum Cellular Automata (QCA) is one of the emerging technologies at nanometric scale for the production of future digital circuits.
#Microchip captures clusters of circulating tumor cells--NIH study Circulating tumor cells (CTCS) are cells that break away from a tumor and move through a cancer patient's bloodstream.
"The new technology--called Cluster-Chip--was developed with support from a Quantum Grant from NIBIB,
Toner and his collaborator Dr. Daniel Haber, M d.,Ph d.,also at MGH, recently used Cluster-Chip to capture
The chip is designed to slowly push blood through many rows of microscopic triangle-shaped posts.
and continue through the chip until reaching the next tip; however CTC clusters are left at the tip,
To determine the efficiency of Cluster-Chip, the researchers introduced fluorescently tagged cell clusters (ranging from 2-30 cells) into the chip
and counted the number of clusters that were captured and the number that flowed through undetected.
At a blood flow rate of 2. 5ml/hr, the chip captured 99 percent of clusters containing four or more cells, 70 percent of three-cell clusters,
Comparison of the clusters under a microscope before and after capture found that the chip had no negative effects on the integrity of the clusters as a whole.
The researchers next compared the efficiency of their novel chip to two currently-used methods that have had some success capturing CTC clusters.
the Cluster-Chip was significantly more efficient than a filter-based method, which pushes blood through a membrane with pores only large enough to let single cells pass through.
The chip was also more efficient than a different microfluidic chip--previously developed by Toner--that isolates CTCS
The results highlight the importance of the unique Cluster-Chip capture technique which is based on the structural properties of CTC clusters rather than their size or the presence of surface proteins.
This latter property makes the Cluster-Chip well-suited for capturing CTC clusters from a range of cancer types,
In this study, the chip captured CTC clusters in 11 of 27 (40.7 percent) breast cancer patients, 6 of 20 (30 percent) melanoma patients
"Toner anticipates that the Cluster-Chip will play an important role in stimulating new research on CTC cluster biology:"

Columbia Engineering researchers first to create a single-molecule diode--the ultimate in miniaturization for electronic devices--with potential for real-world applications Under the direction of Latha Venkataraman, associate professor of applied physics at Columbia Engineering,
ever since its inception with Aviram and Ratner's 1974 seminal paper, represents the ultimate in functional miniaturization that can be achieved for an electronic device."
"With electronic devices becoming smaller every day, the field of molecular electronics has become ever more critical in solving the problem of further miniaturization,
They have shown that single-molecules attached to metal electrodes (single-molecule junctions) can be made to act as a variety of circuit elements
and used gold metal electrodes of different sizes to contact the molecule. Their results achieved rectification ratios as high as 250: 50 times higher than earlier designs.

"Three-dimensional, porous materials have been regarded as an obstacle to building electrodes. But we have proven that this is not a problem.
Superconductors are regarded as one of the most promising candidates for next-generation advanced electronic devices, because the unique quantum effects in superconductors are a great advantage in achieving the energy saving
-273°C)* 1. It has also been a big challenge to realize the high-density integration of superconductors into electronic devices.
The ultrathin high-Tc superconductor would effectively contribute to the significant downsizing and consequent high-density integration in electric circuits,
leading to the realization of future-generation electronic devices with high energy-saving and ultrahigh-speed operation.
The electromagnetic radiation discharged by electronic equipment and devices is known to hinder their smooth operation. Conventional materials used today to shield from incoming electromagnetic waves tend to be sheets of metal or composites,
They're widely expected to improve energy storage, sensors, nanoelectronics, catalysis and separations, but graphene aerogels are prohibitively expensive and difficult to produce for large-scale applications because of the complicated purification
Further potential applications could also be flexible and stretchable electronic devices, luminescent actuators, batteries, smart cloths or sacrificial templates for the growth of new materials.
Molecular machines, novel sensors, bionic materials, quantum computers, advanced therapies and much more can emerge from this endeavour.

From ICFO, focussing on future industrial applications of this new sensor Prof. Valerio Pruneri commented that"the concept can be used in different application fields,

#Iranian Scientists Use Gas Sensor to Detect Hydrogen Iranian researchers designed a sensor with the capability of rapidly detecting the amount of hydrogen existing in the environment.
This sensor can detect the leak of hydrogen in hazardous environment which can prevent the explosion.
Hydrogen sensors are convertors that create electrical signal by adsorbing hydrogen molecules, which depends on the concentration of the hydrogen.
In this research, a capacitor MOS sensor was produced that detects the leak of hydrogen at explosive level (4 vol. percent) in less than two minutes.
Capacitor sensors detect any change in the environment through changing the electrical capacity of the capacitor.
The advantages of these sensors over other types of sensors are stability long lifetime and low response time.
For instance, this sensor can be used in the monitoring of hydrogen concentration during the production of ammonia, methanol and hydration of hydrocarbons.
Among other applications of this sensor, mention can be made of desulfurization of petroleum products, production of jet fuel and launching of aircrafts and other aerospace applications.
This research also studies the effect of the thickness of oxide layers in the sensor structure on its properties and performance.
the sensor detects hydrogen in a shorter period of time as the thickness of oxide layer decreases.
Response time has been calculated to be 84 seconds for a capacitor sensor with oxide layer thickness of 28 nanometers.
Results of the research have been published in Sensors and Actuators B: Chemical, vol. 216, issue 1, 2015, pp. 367-373 3

The one-atom-thick carbon sheets could revolutionize the way electronic devices are manufactured and lead to faster transistors, cheaper solar cells, new types of sensors and more efficient bioelectric sensory devices.
As a potential contact electrode and interconnection material, wafer-scale graphene could be an essential component in microelectronic circuits,
but most graphene fabrication methods are not compatible with silicon microelectronics, thus blocking graphene's leap from potential wonder material to actual profit-maker.
"Our work shows that the carbon ion implantation technique has great potential for the direct synthesis of wafer-scale graphene for integrated circuit technologies."
"In silicon microelectronics, graphene is a potential contact electrode and an interconnection material linking semiconductor devices to form the desired electrical circuits,
For example, recent LANP plasmonic research has led to breakthroughs in color-display technology, solar-powered steam production and color sensors that mimic the eye."
#Researchers boost wireless power transfer with magnetic field enhancement Wireless power transfer works by having a transmitter coil generate a magnetic field;
a receiver coil then draws energy from that magnetic field. One of the major roadblocks for development of marketable wireless power transfer technologies is achieving high efficiency."
By placing the MRFE between the transmitter and the receiver (without touching either) as an intermediate material,
"We realized that any enhancement needs to not only increase the magnetic field the receiver'sees, 'but also not siphon off any of the power being put out by the transmitter,
"Ricketts says.""The MRFE amplifies the magnetic field while removing very little power from the system."
Fibers and cables derived from the invention might one day be used as interconnects for super-elastic electronic circuits;
giant-range strain sensors; failure-free pacemaker leads; and super-stretchy charger cords for electronic devices.
In a study published in the July 24 issue of the journal Science, the scientists describe how they constructed the fibers by wrapping lighter-than-air,
the researchers made strain sensors and artificial muscles in which the buckled nanotube sheaths serve as electrodes
and the thin rubber layer is a dielectric, resulting in a fiber capacitor. These fiber capacitors exhibited a capacitance change of 860 percent

"The asymmetry necessary for diode behavior originates with the different exposed electrode areas and the ionic solution,
"This leads to different electrostatic environments surrounding the two electrodes and superlative single-molecule device behavior."
Since then, development of functional single-molecule electronic devices has been a major pursuit with diodes-one of the most widely used electronic components-being at the top of the list.
A typical diode consists of a silicon p-n junction between a pair of electrodes (anode and cathode) that serves as the"valve"of an electrical circuit,
or through the use of symmetric molecules with different metals as the two electrodes. However, the resulting asymmetric junctions yielded low rectification ratios,
"The efficiency of the tunneling process depends intimately on the degree of alignment of the molecule's discrete energy levels with the electrode's continuous spectrum.
in nearly perfect alignment with the Fermi electron energy levels of the gold electrodes. Symmetry was broken by a substantial difference in the size of the area on each gold electrode that was exposed to the ionic solution.
Owing to the asymmetric electrode area, the ionic solution, and the junction energy level alignment, a positive voltage increases current substantially;
a negative voltage suppresses it equally significantly.""The ionic solution, combined with the asymmetry in electrode areas, allows us to control the junction's electrostatic environment simply by changing the bias polarity,
"Neaton says.""In addition to breaking symmetry, double layers formed by ionic solution also generate dipole differences at the two electrodes,
which is the underlying reason behind the asymmetric shift of molecular resonance. The Columbia group's experiments showed that with the same molecule and electrode setup,
a nonionic solution yields no rectification at all.""The Berkeley Lab-Columbia University team believes their new approach to a single-molecule diode provides a general route for tuning nonlinear nanoscale-device phenomena that could be applied to systems beyond single-molecule junctions
though it doesn't match the lithium ion battery formats commonly used in electronic devices and vehicles.""This is the first time I've seen a capacitor beat a battery on energy density,
