Emerging memory devices used to develop electronic circuits for cybersecurity applications

Thu, 2018-04-26 01:50
While we embrace the way the Internet of Things already is making our lives more streamlined and convenient, the cybersecurity risk posed by millions of wirelessly connected gadgets, devices and appliances remains a huge concern. Even single, targeted attacks can result in major damage; when cybercriminals control and manipulate several nodes in a network, the potential for destruction increases.

3-D print electronics and cells printed directly on skin

Wed, 2018-04-25 22:49
In a groundbreaking new study, researchers used a customized, low-cost 3-D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield to print temporary sensors on their bodies to detect chemical or biological agents or solar cells to charge essential electronics.

Tiny frequency combs are reliable measurement tools

Wed, 2018-04-25 22:49
In an advance that could shrink many measurement technologies, scientists have demonstrated the first miniaturized devices that can generate desired frequencies, or colors, of light precisely enough to be traced to an international measurement standard.

Switch controls light on a nanoscale for faster information processing

Wed, 2018-04-25 22:48
Researchers have helped design a compact switch that enables light to be more reliably confined to small computer chip components for faster information processing.

Precision optical components created with inkjet printing

Wed, 2018-04-25 21:32
Researchers have developed an inkjet printing technique that can be used to print optical components such as waveguides, an approach that could advance a variety of devices such as optical sensors used for health monitoring and lab-on-a-chip devices.

Cheaper and easier way found to make plastic semiconductors

Wed, 2018-04-25 19:07
Cheap, flexible and sustainable plastic semiconductors will soon be a reality thanks to a breakthrough by chemists.

Getting electrons to move in a semiconductor

Tue, 2018-04-24 20:59
Researchers have shown that a wide-bandgap semiconductor called gallium oxide can be engineered into nanometer-scale structures that allow electrons to move much faster within the crystal structure. With electrons that move with such ease, Ga2O3 could be a promising material for applications such as high-frequency communication systems and energy-efficient power electronics.

Path to a new era of microelectronics

Sat, 2018-04-21 02:35
A new microchip technology capable of optically transferring data could solve a severe bottleneck in current devices by speeding data transfer and reducing energy consumption by orders of magnitude, according to a new article.

Rare earth magnet recycling is a grind -- this new process takes a simpler approach

Fri, 2018-04-20 21:59
A new recycling process turns discarded hard disk drive magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste for valuable materials.

Integrating optical components into existing chip designs

Fri, 2018-04-20 02:56
A new technique can assemble optical and electronic components separately on the surface of a computer chip, enabling the addition of optical components to existing chips with little design modification.

Electrochemical tuning of single layer materials relies on defects

Thu, 2018-04-19 22:40
Perfection is not everything, according to an international team of researchers whose 2-D materials study shows that defects can enhance a material's physical, electrochemical, magnetic, energy and catalytic properties.

Researchers design 'soft' robots that can move on their own

Wed, 2018-04-18 23:43
If Star Wars' R2-D2 is your idea of a robot, think again. Researchers have reported a new class of soft robot, composed of ultrathin sensing, actuating electronics and temperature-sensitive artificial muscle that can adapt to the environment and crawl, similar to the movement of an inchworm or caterpillar.

Robot developed for automated assembly of designer nanomaterials

Wed, 2018-04-18 20:46
Engineers have developed a robot that can identify, collect, and manipulate two-dimensional nanocrystals. The robot stacked nanocrystals to form the most complex van der Waals heterostructure produced to date, with much less human intervention than the manual operations previously used to produce van der Waals heterostructures. This robot allows unprecedented access to van der Waals heterostructures, which are attractive for use in advanced electronics.

Flexible TVs and high performance wearable smart tech one step closer

Wed, 2018-04-18 20:41
Flexible televisions, tablets and phones as well as 'truly wearable' smart tech are a step closer thanks to a nanoscale transistor just created.

New tool speeds up the design of wearable tech

Tue, 2018-04-17 21:28
People could soon power items such as their mobile phones or personal health equipment by simply using their daily movements, thanks to a new research tool that could be used by manufacturers.

When nuclei catch up with electrons

Mon, 2018-04-16 23:55
In an attosecond study of the H2 molecule physicists found that for light atomic nuclei -- as contained in most organic and biological molecules -- the correlation between electronic and nuclear motions cannot be ignored.

Some superconductors can also carry currents of 'spin'

Mon, 2018-04-16 21:46
Researchers have shown that certain superconductors -- materials that carry electrical current with zero resistance at very low temperatures -- can also carry currents of 'spin'. The successful combination of superconductivity and spin could lead to a revolution in high-performance computing, by dramatically reducing energy consumption.

When superconductivity disappears in the core of a quantum tube

Fri, 2018-04-13 23:06
Predicting the behavior of electrons in a material is not easily done. Physicists have replaced the electrons with ultra-cold neutral lithium atoms that they had circulated in a one-dimensional quantum tube. The scientists were able to confirm an unusual state of matter that retains its insulation regardless of the level of attraction between the particles. This work opens the way to new materials with atypical properties.
