Single-molecule diode created

Tue, 2017-04-25 20:39
Researchers have created a diode out of a 1 nm-sized single molecule with high rectification ratios. Diodes, commonly used in in everyday electronic devices, allow current to flow in one direction while blocking the current in the opposite direction. Today, researchers are approaching the physical limit in downsizing electronic components.

Mon, 2017-04-24 19:46
A new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable has now been developed, providing new possibilities such as flexible smartphones. His new technique uses ice-templating to control the structure of the solid electrolyte for lithium batteries that are used in portable electronics, electric vehicles, and grid-level energy storage.

New breakthrough in battery charging technology

Mon, 2017-04-24 19:42
A new study has introduced a new battery charging technology that uses light to charge batteries. This newly-developed power source is designed to work under sunlight and indoor lighting, allowing users to power their portable electronics anywhere with access to light. In addition, the new device could power electric devices even in the absence of light.

Revealing polymeric fluids behavior at the microscopic scale

Mon, 2017-04-24 19:09
An important concept in future healthcare is the development of devices called “lab on a chip”. These “chips” are injected to fill specifically designed microscopic channels. These channels contain biosensors which detect, for example, specific markers for diseases within the fluid and provide a quick diagnosis. However, an arising issue is the size of the fluid sample injected inside the chip, with tiny volumes down to a billionth of a liter. Due to lack of available technologies, researchers do not yet fully understand how fluids – particularly complex ones of biological origins – behave at such small scales.

Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Sat, 2017-04-22 06:38
Reflecting the structure of composites found in nature and the ancient world, researchers have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

Simultaneously simulating electrical and optical input achieves unprecedented performance in electro-optical interfaces, report investigators.

Graphene 'copy machine' may produce cheap semiconductor wafers

Wed, 2017-04-19 22:47
A new technique may vastly reduce the overall cost of wafer technology and enable devices made from more exotic, higher-performing semiconductor materials than conventional silicon. The new method uses graphene -- single-atom-thin sheets of graphite -- as a sort of 'copy machine' to transfer intricate crystalline patterns from an underlying semiconductor wafer to a top layer of identical material.

Wed, 2017-04-19 20:54
Researchers have used waste glass bottles and a low-cost chemical process to create nanosilicon anodes for high-performance lithium-ion batteries. The batteries will extend the range of electric vehicles and plug-in hybrid electric vehicles, and provide more power with fewer charges to personal electronics like cell phones and laptops.

Degradable electronic components created from corn starch

Wed, 2017-04-19 19:38
As consumers upgrade their gadgets at an increasing pace, the amount of electronic waste we generate continues to mount. To help combat this environmental problem, researchers have modified a degradable bioplastic derived from corn starch or other natural sources for use in more eco-friendly electronic components.

New method can model chemistry in extreme magnetic fields of white dwarfs

Wed, 2017-04-19 00:42
Approximately 10-20 percent of white dwarfs exhibit strong magnetic fields, which can reach up to 100,000 tesla. However, on Earth, the strongest magnetic fields that can be generated using nondestructive magnets are about 100 tesla. Therefore, studying the chemistry in such extreme conditions is only possible using theory and until now has not provided much insight to the spectra accompanying white dwarfs.

Mon, 2017-04-17 21:17
Engineers have invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas. They built photonic integrated devices that had record-small footprints and were also able to maintain optimal performance over an unprecedented broad wavelength range. The method could lead to faster, more powerful, and more efficient optical chips, which in turn could transform optical communications and optical signal processing.

Low haze structures for transparent flexible electrodes by electrospinning processes

Thu, 2017-04-13 18:18
For flexible electrodes, researchers are working with the process of electrospinning, a technique that produces ultra-fine fibers that are up to 100 times thinner than a human hair. These fibers are collected on glass or on foils in an unstructured, wide mesh net. When conductive materials are spun, flexible conductive transparent electrodes could be produced. These FTCEs have transparencies comparable to indium tin oxide with low haze less than two percent.
