A new theoretical model explains the coupling between ions and electrons in the widely used conducting polymer PEDOT:PSS. The model has profound implications for applications in printed electronics, energy storage in paper, and bioelectronics.
Researchers successfully constructed a first-of-its-kind chemical oscillator that uses DNA components. DNA molecules that follow specific instructions could offer more precise molecular control of synthetic chemical systems, a discovery that opens the door for engineers to create molecular machines with new and complex behaviors.
Engineers have demonstrated a method for gathering blood pressure, heart rate and breath rate using a cheap and covert system of radio-frequency signals and microchip 'tags,' similar to the anti-theft tags department stores place on clothing and electronics.
A standard machining technique has been used to fabricate a 'nanofluidic staircase' that allows precise measurement of the size of nanoparticles in a liquid, report scientists.
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.
Researchers have managed to stabilize short-lived radical ions which could be used for rechargeable batteries.
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.
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.
Researchers have predicted and demonstrated a giant spin anisotropy in graphene, paving the way for new spintronic logic devices.
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.
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 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.
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.
Scientists have developed an entirely textile-based, bacteria-powered bio-battery that could one day be integrated into wearable electronics.
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.
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.
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.
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".
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.
