Accelerating the self-assembly of nanoscale patterns for next-generation materials

Wed, 2017-12-13 23:34
Scientists have come up with a way to massively speed up the ordering process for self-assembling materials. The resulting ultra-small, well-ordered patterns could be used in the fabrication of microelectronics, antireflective surfaces, magnetic data storage systems, and fluid-flow devices.

Batteries: Catching radical molecules before they disappear

Wed, 2017-12-13 20:22
Researchers have managed to stabilize short-lived radical ions which could be used for rechargeable batteries.

Engineers create artificial graphene in a nanofabricated semiconductor structure

Wed, 2017-12-13 05:11
Experts at manipulating matter at the nanoscale have made an important breakthrough in physics and materials science. They have engineered "artificial graphene" by recreating, for the first time, the electronic structure of graphene in a semiconductor device.

Researchers make solid ground toward better lithium-ion battery interfaces

Wed, 2017-12-13 00:44
New research has identified a major obstacle to advancing solid-state lithium-ion battery performance in small electronics: the flow of lithium ions across battery interfaces.

Graphene spin transport takes a step forward towards applications

Tue, 2017-12-12 00:34
Researchers have predicted and demonstrated a giant spin anisotropy in graphene, paving the way for new spintronic logic devices.

Revolutionizing electronics using Kirigami

Sat, 2017-12-09 01:53
A research team has developed an ultrastretchable bioprobe using a 'Kirigami' designs. The Kirigami-based bioprobe enables one to follow the shape of spherical and large deformable biological samples such as heart and brain tissues. In addition, its low strain-force characteristic reduces the force induced on organs, thereby enabling minimally invasive biological signal recording.

Many more bacteria have electrically conducting filaments

The microbiologists who have discovered electrically conducting microfilaments or 'nanowires' in the bacterium Geobacter, announce in a new article that they have discovered the unexpected structures in many other species, greatly broadening the research field on electrically conducting filaments.

Chemists synthesize narrow ribbons of graphene using only light and heat

Fri, 2017-12-08 19:23
Chemists have developed a new method to produce graphene nanoribbons, which are widely viewed as a next-generation material that might one day power the world's electronic devices.

Device makes power conversion more efficient

Fri, 2017-12-08 02:15
Researchers have presented a new design that, in tests, enabled gallium nitride power devices to handle voltages of 1,200 volts. That's already enough capacity for use in electric vehicles, but the researchers believe that further work can boost its capacity to the 3,300-to-5,000-volt range, to bring the efficiencies of gallium nitride to the power electronics in the electrical grid itself.

Tue, 2017-12-05 21:11
Researchers have successfully measured some of the quantum properties of electrons in two-dimensional semiconductors. This work in the field of spintronics could one day lead to chips that are not only smaller but that also generate less heat.

Humidity switches molecular diode off and on

Tue, 2017-12-05 01:37
Molecular electronics is a growing research area where scientists study electrical properties of the molecules with a chemically programmed function. Molecules can function as diodes, switches and transistors, all with a typical length of few nanometers. An international group of scientists has developed the first switchable molecular diode.

Subnanometer-scale channels in 2-D materials could point toward future electronics and solar cells, report investigators.

Graphene nano 'tweezers' can grab individual biomolecules

Sat, 2017-12-02 01:39
Researchers have found yet another remarkable use for the wonder material graphene -- tiny electronic 'tweezers' that can grab biomolecules floating in water with incredible efficiency. This capability could lead to a revolutionary handheld disease diagnostic system that could be run on a smart phone.

Lightweight, compact VR glasses made possible by large-area microdisplays

Fri, 2017-12-01 21:17
Virtual reality (VR) glasses are increasingly popular, but they have usually been heavy and oversized -- until now. Large-area microdisplays are expected to change that, because they make it possible to produce ergonomic and lightweight VR glasses. The new OLED displays now reach very high frame rates and achieve extremely high resolutions with "extended full HD".

Monitoring security glass panes: Smart alarm system recognizes attempted break-ins

Fri, 2017-12-01 21:17
There is a huge selection of glass break detectors on the market. Although these detectors reliably trigger an alarm when window panes break, they do not register all other ways in which burglars can interfere with a pane. To counter this, researchers have created a new type of alarm system that recognizes any attempt to manipulate the window. It registers temperature changes in real time as well as vibrations caused by external interference with the glass, leaving burglars with no chance.

Squeezing light into a tiny channel brings optical computing a step closer

Fri, 2017-12-01 00:40
By forcing light to go through a smaller gap than ever before, researchers have paved the way for computers based on light instead of electronics.

The future of electronics: New catalytic effect discovered for producing gallium oxide

Thu, 2017-11-30 20:09
Semiconducting oxides are a new class of materials that are currently enjoying great attention in the field of semiconductor technology. Gallium oxide is the archetypal example for its ability to handle extremely high voltages and its optical transparency in the deep ultraviolet region. Such components are based on very thin, ultrapure semiconductor layers produced by special deposition methods. Physicists have now drastically increased the yield of gallium oxide with a catalytic effect observed for the first time during crystal growth.
