Transistor sets a new standard for energy efficiency (14/05/2020)

Smartphones, laptops and smartwatches consume vast quantities of energy, yet only around half of this energy is actually used to power important functions. And with billions of these devices in use worldwide, a significant amount of energy goes to waste. Professor Adrian Ionescu and his team at EPFL's Nanoelectronic Devices Laboratory (Nanolab) have launched a series of research projects in the quest to make transistors more energy-efficient. 

Transporting energy through a single molecular nanowire (13/05/2020)

Photosynthetic systems in nature transport energy very efficiently toward a reaction center, where it is converted into a useful form for the plant. Scientists have been using this as inspiration to learn how to transport energy efficiently in molecular electronics and other technologies. Physicist Richard Hildner from the University of Groningen and his colleagues have investigated energy transport in an artificial system made from nanofibers. The results were published in the Journal of the American Chemical Society.

A new electrolyte design that could enhance the performance of Li-ion batteries (13/05/2020)

Most existing lithium-ion batteries (LIBs) integrate graphite anodes, which have a capacity of approximately 350 milliamp hours (mAh) per gram. The capacity of silicon anodes is almost 10 times higher than that of their graphite counterparts (around 2,800 mAh per gram), and could thus theoretically enable the development of more compact and lighter lithium-based batteries.

Chemistry breakthrough could speed up drug development (11/05/2020)

Scientists have successfully developed a new technique to reliably grow crystals of organic soluble molecules from nanoscale droplets, unlocking the potential of accelerated new drug development.

Scientists create new nanocomposite from gold and titanium oxide (10/05/2020)

Oxides of different metals often serve as photocatalysts in various systems such as air purification, reactions of water decomposition and even in the production of self-cleaning surfaces for glass and mirrors. The physical-chemical properties of such materials can be improved by adding nanoparticles, which turn an ordinary oxide into a nanomaterial with new capabilities. 

Shedding new light on nanolasers using 2-D semiconductors (07/05/2020)

In his latest line of research, Cun-Zheng Ning, a professor of electrical engineering in the Ira A. Fulton Schools of Engineering at Arizona State University, and his peers explored the intricate balance of physics that governs how electrons, holes, excitons and trions coexist and mutually convert into each other to produce optical gain. Their results, led by Tsinghua University Associate Professor Hao Sun, were recently published in the Nature publication Light: Science & Applications.

AI devising a more equitable tax system (07/05/2020)

Everybody loves to hate taxes. And unless you are lucky enough to live in one of a small handful of countries with no income tax—Bermuda, Monaco or the United Arab Emirates, for instance—you likely dread Tax Day when you dig deep into your pockets and send a chunk of your hard-earned cash to government coffers.

Imaging technology allows visualization of nanoscale structures inside whole cells (07/05/2020)

Since Robert Hooke's first description of a cell in Micrographia 350 years ago, microscopy has played an important role in understanding the rules of life.

Tiny devices promise new horizon for security screening and medical imaging (07/05/2020)

Miniature devices that could be developed into safe, high-resolution imaging technology, with uses such as helping doctors identify potentially deadly cancers and treat them early, have been created in research involving the University of Strathclyde

Researchers discover ferroelectricity at the atomic scale (07/05/2020)

As electronic devices become progressively smaller, the technology that powers them needs to get smaller and thinner.
