#Aluminum"yolk"nanoparticles deliver high-capacity battery recipe Researchers at MIT and Tsinghua University in China have found a way to more than triple the capacity of the anodes,
or negative electrodes, of lithium-ion batteries while also extending their lifetime and potentially allowing for faster battery charging
The new electrode, which makes use of aluminum/titanium"yolk -and-shell"nanoparticles, is reportedly simple to manufacture
The lithium-ion batteries in our phones, tablets and laptops store their energy-carrying ions inside negative electrodes made of graphite.
Other electrode materials could in theory do a far better job by packing in more energy

because the repeated expansion and shrinkage inside the electrode cause aluminium particles to shed their outer layer.
Encasing the aluminum particles within a titanium dioxide shell, however, prevents the shedding, again prolonging the cell's lifetime.
the new electrode can reportedly store over three times as much energy per unit mass (1. 2 Ah/g) at a normal charging rate.

and research team member, Jacques Carolan.""We carried out a year worth of experiments in a matter of hours.
What wee really excited about is using these chips to discover new science that we haven even thought of yet...
This chip has been fabricated and packaged up, so that we never need to realign it. It sits there,
with plans to add even more chips in the near future.""Over the last decade, we have established an ecosystem for photonic quantum technologies,
and SLAC, contains 189 sensors, has a resolution equivalent to 800,000 eight-megapixel cameras, and includes a filter-changing mechanism and shutter for viewing different wavelengths from the near-ultraviolet to the near-infrared.
the human body is becoming host to an ever-increasing array of electronic devices that need to wirelessly communicate with each other.
such as smartwatches, implanted smart monitors, or even ingestible wireless sensors, generally requires that each of these transmit to a receiver using Bluetooth.
Since the electromagnetic radiation used by Bluetooth to transmit data does not easily pass through the human body,
and therefore also carry relatively bulky batteries to power their transmitters. Though still in development, the engineers say their new system is superior to existing radio communications technologies in this field,
"In the future, people are going to be wearing more electronics, such as smart watches, fitness trackers and health monitors,"says Patrick Mercier,
At one end of this arrangement, the wires terminate at a receiver and analyzer, while at the other end the wires are formed into coils that wind around three parts of the body:
In this way, the coils act as inductors for the application of energy and the production of magnetic fields and allow the body itself to act as a sort of waveguide for those fields.
Using this system, the researchers were able to transmit and measure ultra-low path loss signals from from arm to arm, from arm to head,
but it would also reduce the size of ingestible transmitters to something much easier to swallow."
The feat was accomplished by running wires connected to electrodes on the patient's sensory cortex (the part of the brain responsible for identifying tactile sensations)
Torque sensors integrated into the device are able to detect when pressure is being applied to the prosthesis,

#Boron-doped graphene to enable ultrasensitive gas sensors As an atom-thick, two-dimensional material with high conductivity,
graphene is set to enable a stream of new electronic devices, including particularly sensitive sensors for the detection of various gases,
such as those produced by explosives. Now an international team of researchers led by Pennsylvania State university (Penn State) has created a graphene-boron amalgam that can detect particular gases down to mere parts per billion,
and may eventually lead to detectors with such sensitivity that they could detect infinitesimally tiny amounts of gas in the order of parts per quadrillion.
the researchers created sensors that are able to detect gas molecules at exceptionally low concentrations;
where they were compared then with known highly sensitive gas sensors. At the same time, the Novoselov lab at the University of Manchester, UK (where graphene was synthesized first

But an experimental sensor that clings to skin like a temporary tattoo could enable 24-hour monitoring of blood flow wherever a patient goes.
A wearable sensor could mean the difference between taking what is essentially a snapshot of a patient health
Webb and his colleagues turned to flexible electronics technology to find a possible wearable solution.

Most of the sensor bulk comes from a 40-micrometer-thick layer of silicone. Each of the other layers has a thickness of just tens or hundreds of nanometers.
Two rings of sensors around the actuator detect the temperature differences in the heat patterns with a precision within 0. 01 degrees Celsius.
Such flexible sensors could also be placed on internal organs, surgical tools, or implantable devices. For now, Webb and his colleagues continue to refine the heat-mapping blood flow device with the goal of making it smaller.

#Scientists Create LEDS From Food, Beverage Waste Most Christmas lights, DVD players, televisions and flashlights have one thing in common:
theye made with light emitting diodes (LEDS. LEDS are used widely for a variety of applications
and have been a popular, more efficient alternative to fluorescent and incandescent bulbs for the past few decades.
Two University of Utah researchers have now found a way to create LEDS from food and beverage waste.
this development can also reduce potentially harmful waste from LEDS generally made from toxic elements.
LEDS are a type of device that can efficiently convert electricity to light. Unlike fluorescent and incandescent bulbs,
LEDS direct 80 percent of the energy consumed to producing light. This is made possible by the fact that LEDS do not require a filament to be heated as incandescent and fluorescent bulbs do.
LEDS can be produced by quantum dots, or tiny crystals that have luminescent properties. Quantum dots (QDS) can be made with numerous materials, some
of which are rare and expensive to synthesize, and even potentially harmful to dispose of. Some research over the past 10 years has focused on using carbon dots (CDS),
to create LEDS instead. Compared to other types of quantum dots CDS have lower toxicity and better biocompatibility,
and subsequently, LEDS. The results were published recently in Physical chemistry Chemical Physics, a journal of the Royal Society of Chemistry.
heated and hardened to solidify the CDS for practical use in LEDS. An environmentally sustainable alternative Currently, one of the most common sources of QDS is cadmium selenide,
To be able to use this waste for creating LEDS which are used widely in a number of technologies would be an environmentally sustainable approach.
Looking forward Sarswat and Free hope to continue studying the LEDS produced from food and beverage waste for stability
and to use these LEDS in everyday devices. To successfully make use of waste that already exists, that the end goal,

#3d Computer Chips Could Be 1, 000 Times Faster Than Existing Ones A new method of designing and building computer chips could lead to blisteringly quick processing at least 1,
000 times faster than the best existing chips are capable of, researchers say. The new method,
which relies on materials called carbon nanotubes, allows scientists to build the chip in three dimensions. The 3d design enables scientists to interweave memory,
and the number-crunching processors in the same tiny space, said Max Shulaker, one of the designers of the chip,
Progress slowing The inexorable advance in computing power over the past 50 years is largely thanks to the ability to make increasingly smaller silicon transistors,
According to Moore's law, a rough rule first articulated by semiconductor researcher Gordon E. Moore in 1965, the number of transistors on a given silicon chip would roughly double every two years.
True to his predictions, transistors have gotten ever tinier with the teensiest portions measuring just 5 nanometers,
Beyond that, shrinking transistors to the bitter end may not do much to make computers faster. Long commute time The main roadblock to faster computers is not flagging processor speed,
Carbon nanotubes (CNTS) have electrical properties similar to those of conventional silicon transistors. In a head-to-head competition between a silicon transistor and a CNT transistor,"hands down, the CNT would win,
"Shulaker told Live Science.""It would be a better transistor; it can go faster; it uses less energy."
"However, carbon nanotubes grow in a disorderly manner, "resembling a bowl of spaghetti, "which is no good for making circuits,
the researchers figured out that drilling holes at certain spots within the chip can ensure that even a chip with wayward tubes would work as expected.
while most CNTS have the properties of a semiconductor (like silicon), a few act just like an ordinary conducting metal,
Those few conducting tubes can ruin an entire chip, and having to toss even a fraction of the chips wouldn't make financial sense, Shulaker added.
As a remedy, Shulaker and his colleagues essentially"turn off"all the semiconducting CNTS, leaving huge jolts of current to circulate through the remaining conducting nanotubes.
however, was slow and bulky, with relatively few transistors. Now, they have created a system for stacking memory and transistor layers,
