Jul 14, 2022 (Nanowerk News) Whether it is cars, energy or mobile phones: modern society is built on metals and our future strongly depends on these materials, too. To store hydrogen in a safe, compact and still environmentally friendly way is still a major challenge. Metal hydrides could be an...
Rewinding a supernova with machine learning
Jul 14, 2022 (Nanowerk News) New work looks at using machine learning to decipher the early stages of supernovae explosions by reconstructing the light emitted during the outburst. The research was presented at the 2022 National Astronomy Meeting by Eleonora Parrag, a PhD student at the University of Cardiff. The...
Fully scalable all-perovskite tandem solar modules
Jul 14, 2022 (Nanowerk News) Researchers at the Karlsruhe Institute of Technology (KIT) have developed a prototype for fully scalable all-perovskite tandem solar modules. These modules have an efficiency of up to 19.1 percent with an aperture area of 12.25 square centimeters. This result, the first of its kind reported...
A robot learns to imagine itself
Jul 14, 2022 (Nanowerk News) As every athletic or fashion-conscious person knows, our body image is not always accurate or realistic, but it’s an important piece of information that determines how we function in the world. When you get dressed or play ball, your brain is constantly planning ahead so...
Turning white blood cells into medicinal microrobots with light
Jul 13, 2022 (Nanowerk News) Medicinal microrobots could help physicians better treat and prevent diseases. But most of these devices are made with synthetic materials that trigger immune responses in vivo. Now, for the first time, researchers reporting in ACS Central Science ("Optically Manipulated Neutrophils as Native Microcrafts In Vivo")...
‘Life-like’ lasers can self-organize, adapt their structure, and cooperate
Jul 13, 2022 (Nanowerk News) While many artificial materials have advanced properties, they have a long way to go to combine the versatility and functionality of living materials that can adapt to their situation. For example, in the human body bone and muscle continuously reorganise their structure and composition to...
Smart thermostats inadvertently strain electric power grids
Jul 13, 2022 (Nanowerk News) Set by default to turn on before dawn, smart thermostats unintentionally work in concert with other thermostats throughout neighborhoods and regions to prompt inadvertent, widespread energy-demand spikes on the grid. The smart thermostats are saving homeowners money, but they are also initiating peak demand throughout...
Astronomers detect a radio ‘heartbeat’ billions of light-years from Earth
Jul 13, 2022 (Nanowerk News) Astronomers at MIT and elsewhere have detected a strange and persistent radio signal from a far-off galaxy that appears to be flashing with surprising regularity. The signal is classified as a fast radio burst, or FRB — an intensely strong burst of radio waves of...
A combined multiscale modeling and experimental study on surface modification of high-volume micro-nanoparticles with atomic accuracy
Jul 13, 2022 (Nanowerk News) Surface modification of micro-nanoparticles at the atomic and close-to-atomic scales is of great importance to their applications in a variety of fields, such as energy storage, catalysis, sensors, biomedicine, etc. In order to meet the industry requirements in these areas, it is urgently necessary to...
Graphene oxide elastin membranes for surgical dressings shown to prevent recurrence of melanoma and enhance healing
Jul 13, 2022 (Nanowerk News) Scientists from the University of Nottingham have combined graphene oxide, elastin, and ethanol to develop a new method to make this material conductive so it can be heated to kill melanoma cells but not other cells around it. The research has been published in Advanced...
