Supersonic waves may help electronics beat the heat

Thu, 2018-05-17 23:55
Researchers made the first observations of waves of atomic rearrangements, known as phasons, propagating supersonically through a vibrating crystal lattice -- a discovery that may dramatically improve heat transport in insulators and enable new strategies for heat management in future electronics devices.

Self-assembling 3D battery would charge in seconds

Thu, 2018-05-17 23:55
The world is a big place, but it's gotten smaller with the advent of technologies that put people from across the globe in the palm of one's hand. And as the world has shrunk, it has also demanded that things happen ever faster -- including the time it takes to charge an electronic device.

Materials scientists develop new forming technology: Processing glass like a polymer

Thu, 2018-05-17 19:53
Pure quartz glass is highly transparent and resistant to thermal, physical, and chemical impacts. These are optimum prerequisites for use in optics, data technology or medical engineering. For efficient, high-quality machining, however, adequate processes are lacking. Scientists have developed a forming technology to structure quartz glass like a polymer.

Researchers control the properties of graphene transistors using pressure

Wed, 2018-05-16 22:41
Researchers have developed a technique to manipulate the electrical conductivity of graphene with compression, bringing the material one step closer to being a viable semiconductor for use in today's electronic devices.

Glass-forming ability: Fundamental understanding leading to smart design

Wed, 2018-05-16 22:07
Researchers studied the glass-forming ability of two simple systems, establishing the 'thermodynamic interface penalty,' which is an indicator of the extent of the structural difference between a crystal and its melt. The fundamental understanding acquired is expected to lead to physics-driven design of glassy materials, allowing for better control and tailoring, and aiding advances in the manufacture of numerous materials including metallic alloys.

New device could increase battery life of electronics by a hundred-fold

Wed, 2018-05-16 22:06
Among the chief complaints for smartphone, laptop and other battery-operated electronics users is that the battery life is too short and -- in some cases -- that the devices generate heat. Now, a group of physicists has developed a device material that can address both issues. The team has applied for a patent for a magnetic material that employs a unique structure -- a 'honeycomb' lattice that exhibits distinctive electronic properties.

Plug-and-play diagnostic devices

Wed, 2018-05-16 19:53
Researchers have developed modular blocks that can be put together in different ways to produce diagnostic devices. These 'plug-and-play' devices can test blood glucose levels in diabetic patients or detect viral infection, among other functions.

High-sensitivity microsensors on the horizon

Tue, 2018-05-15 00:49
A new article explains how scientists borrowed concepts from quantum mechanics to build new microsensors that can enable data gathering from hard-to-monitor environments.

Engineers on a roll toward smaller, more efficient radio frequency transformers

Mon, 2018-05-14 21:55
The future of electronic devices lies partly within the 'internet of things' -- the network of devices, vehicles and appliances embedded within electronics to enable connectivity and data exchange. Engineers are helping realize this future by minimizing the size of one notoriously large element of integrated circuits used for wireless communication -- the transformer.

How a pinch of salt can improve battery performance

Mon, 2018-05-14 19:25
Researchers have discovered how a pinch of salt can be used to drastically improve the performance of batteries.

Shedding light on a cyclic molecule with a twist

Mon, 2018-05-14 18:45
As suggested by their name, Möbius molecules have a twisted loop structure, a special characteristic with many potential applications. A research team has revealed the properties of a type of Möbius aromatic molecule that expresses magnetism and retains high energy levels when exposed to light. These characteristics could potentially be applied in organic solar batteries, lights, and conductive materials.

Waterloo chemists create faster and more efficient way to process information

Fri, 2018-05-11 17:41
Chemists have found a much faster and more efficient way to store and process information by expanding the limitations of how the flow of electricity can be used and managed.

Strain improves performance of atomically thin semiconductor material

Thu, 2018-05-10 21:20
Materials scientists show conclusively for the first time that the properties of atomically thin materials can be mechanically manipulated to enhance their performance. The finding could lead to faster computer processors and more efficient optical sensors.

Battery-free 'smart' toys move closer to commercial reality

Wed, 2018-05-09 21:46
Scientists report they have used specialized nanogenerators that gather energy from mechanical vibrations to transform squeaky bathtub companions and other conventional children's toys into 'smart' electronics. They say the finding could have broad commercial applications, leading to the development of battery-free, self-powered toys, medical sensors and other devices.

Flexible, wearable oral sodium sensor could help improve hypertension control

Tue, 2018-05-08 01:00
For people who have hypertension and certain other conditions, eating too much salt raises blood pressure and increases the likelihood of heart complications. To help monitor salt intake, researchers have developed a flexible and stretchable wireless sensing system designed to be comfortably worn in the mouth to measure the amount of sodium a person consumes.

3-D batteries pack power into tiny footprints

Thu, 2018-05-03 23:59
Batteries might seem like they come in every shape and size that you can imagine. But as electronic devices become tinier and skinnier without reducing their power and energy demands, they challenge engineers to design batteries that can fit into smaller spaces without compromising on performance. Researchers have used non-traditional techniques to fashion one possible solution -- a powerful 3-D lithium ion battery with a footprint on the order of one hundred grains of salt.

Atomically thin magnetic device could lead to new memory technologies

Thu, 2018-05-03 23:57
Scientists have discovered a method to encode information using magnets that are just a few layers of atoms in thickness. This breakthrough may revolutionize both cloud computing technologies and consumer electronics by enabling data storage at a greater density and improved energy efficiency.
