Aug 10, 2022 (Nanowerk News) The ongoing fourth industrial revolution is data-driven and the optical interconnects are expected to feature higher bandwidth, smaller footprint, and lower power consumption to meet the dramatically growing demand for stronger data processing ability. As a key element of the optical communication systems, a photodetector...
3D printing of starch for personalised medicine development
Aug 09, 2022 (Nanowerk News) For the purpose of personalised therapies, the UPV/EHU’s ‘Materials+Technologies’ (GMT) Group has used 3D printing to develop tablets based on different types of starch, and has confirmed that drug release could be tailored by optimising the right starch type and tablet shape. Traditional methods produce...
First-ever detection of gas in a circumplanetary disk
Aug 09, 2022 (Nanowerk News) Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA)— in which the National Radio Astronomy Observatory (NRAO) is a partner— to study planet formation have made the first-ever detection of gas in a circumplanetary disk. What’s more, the detection also suggests the presence of a very...
Chemists achieve ‘molecular editing’ feat
Aug 09, 2022 (Nanowerk News) Chemists from Scripps Research and the University of California, Los Angeles, have developed methods for the precise, flexible modification of a broad class of chemical compounds called bicyclic aza-arenes, which are commonly used to build drug molecules. The landmark achievement, reported in Nature ("Molecular editing...
Human-machine interfaces work underwater, generate their own power
Aug 09, 2022 (Nanowerk News) Wearable human-machine interface devices, HMIs, can be used to control machines, computers, music players, and other systems. A challenge for conventional HMIs is the presence of sweat on human skin. In Applied Physics Reviews ("A programmable magnetoelastic sensor array for self-powered human-machine interface"), scientists at...
Scientists improve the power output of triboelectric nanogenerators with carbon particles
Aug 09, 2022 (Nanowerk News) Most of us have felt the shock from static electricity by touching a metallic object after putting on a sweater or walking across a carpet. This occurs as a result of charge build-up whenever two dissimilar materials (such as our body and the fabric) come...
Physicists switch magnetic state using spin current
Aug 09, 2022 (Nanowerk News) When Carnegie Mellon University doctoral candidates I-Hsuan Kao and Ryan Muzzio started working together a switch flicked on. Then off. Working in the Department of Physics' Lab for Investigating Quantum Materials, Interfaces and Devices (LIQUID) Group, Kao, Muzzio and other research partners were able to...
Do ‘bouncing universes’ have a beginning?
Aug 09, 2022 (Nanowerk News) In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles. Because this behavior is hypothesized to be perpetual, the universe should have no beginning and no end — only eternal cycles of growing and...
Scientists offer blueprint for sustainable redesign of food systems
Aug 09, 2022 (Nanowerk News) The researchers describe food systems designed not by the logic of growth such as efficiency and extraction, but by principles of sufficiency, regeneration, distribution, commons, and care. They argue that food systems can instead be the foundation of healthy communities, ecologies and economies. “For this...
Environmental impact of 57,000 multi-ingredient processed foods revealed
Aug 09, 2022 (Nanowerk News) A study estimating the environmental impact of 57,000 food products in the UK and Ireland has been published by an Oxford-led research team in the journal PNAS ("Estimating the environmental impacts of 57,000 food products"). The paper compares the environmental impacts of meat and meat...
