Feb 23, 2024 (Nanowerk News) A material coating, whose light refraction properties can be precisely switched between different states, has been developed by an interdisciplinary research team from the Chemistry and Physics departments at the University of Jena. The team, led by Felix Schacher, Sarah Walden, Purushottam Poudel, and Isabelle...
Lab-spun sponges form perfect scaffolds for growing skin cells to heal wounds
Feb 23, 2024 (Nanowerk News) A new technique for electrospinning sponges has allowed scientists from the University of Surrey to directly produce 3D scaffolds – on which skin grafts could be grown from the patient’s own skin. Electrospinning is a technique which electrifies droplets of liquid to form fibres from...
New structural insights could lead to mechanical enhancement in alloys
Feb 23, 2024 (Nanowerk News) A new class of metallic materials with potential applications in airplane turbines, nuclear reactors and equipment for space exploration can withstand extreme temperatures and resist fractures, but scientists haven’t understood why until now. According to a new study co-led by Penn State researchers, the answer...
Scientists closer to solving mysteries of universe after measuring gravity in quantum world
Feb 23, 2024 (Nanowerk News) Scientists are a step closer to unravelling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force which was discovered by Isaac Newton works in the tiny quantum world. Even...
Engineers 3D print the electromagnets at the heart of many electronics
Feb 23, 2024 (Nanowerk News) Imagine being able to build an entire dialysis machine using nothing more than a 3D printer. This could not only reduce costs and eliminate manufacturing waste, but since this machine could be produced outside a factory, people with limited resources or those who live in...
Flexible sensor uniquely mimics complex touch and perception of human skin
Feb 23, 2024 (Nanowerk Spotlight) Our skin endows us with a profoundly multifaceted sensory awareness unmatched in machines. Human touch conveys intricate patterns of pressure, thermal flow and subsurface textures. It simultaneously maps moisture, contours and minute disturbances in the air. This combination enables astounding environmental comprehension through the body’s...
Researchers harness 2D magnetic materials for energy-efficient computing
Feb 22, 2024 (Nanowerk News)Experimental computer memories and processors built from magnetic materials use far less energy than traditional silicon-based devices. Two-dimensional magnetic materials, composed of layers that are only a few atoms thick, have incredible properties that could allow magnetic-based devices to achieve unprecedented speed, efficiency, and scalability. While...
New electrochemical system enables efficient metal recovery from industrial wastewater
Feb 22, 2024 (Nanowerk News) A research team at Tsinghua University led by Professor Huijuan Liu has developed a new electrochemical system that promises to revolutionize metal recovery from industrial wastewater. The research was published in Engineering ("Efficient Metal Recovery from Industrial Wastewater: Potential Oscillation and Turbulence Mode for Electrochemical...
James Webb telescope detects traces of neutron star in iconic supernova
Feb 22, 2024 (Nanowerk News) Supernovae are the spectacular end result of the collapse of stars more massive than 8-10 times the mass of the sun. Besides being the main sources of chemical elements such as carbon, oxygen, silicon, and iron that make life possible, they are also responsible for...
A new chapter for all-attosecond spectroscopy
Feb 22, 2024 (Nanowerk News) A team of researchers from the Max Born Institute in Berlin has for the first time demonstrated attosecond-pump attosecond-probe spectroscopy (APAPS) at a repetition rate of 1 kilohertz. This became possible by the development of a compact intense attosecond source using an out-of-focus generation geometry....
