Apr 14, 2022 (Nanowerk News) Human organ transplants offer a crucial lifeline to people with serious illnesses, but there are too few organs to go around: in the U.S. alone, there are more than 112,000 people currently waiting for transplants. The promise of 3D printing organs is one possible solution...
Researchers create miniature wide-angle camera with flat metalenses
Apr 14, 2022 (Nanowerk News) Researchers have designed a new compact camera that acquires wide-angle images of high-quality using an array of metalenses — flat nanopatterned surfaces used to manipulate light. By eliminating the bulky and heavy lenses typically required for this type of imaging, the new approach could enable...
Graphene-hBN breakthrough to spur new LEDs, quantum computing
Apr 14, 2022 (Nanowerk News) In a discovery that could speed research into next-generation electronics and LED devices, a University of Michigan research team has developed the first reliable, scalable method for growing single layers of hexagonal boron nitride on graphene. The process, which can produce large sheets of high-quality...
MAGIC telescopes observe nova explosion shining brightly in gamma rays at extremely high energy
Apr 14, 2022 (Nanowerk News) The MAGIC telescopes have observed the nova RS Ophiuchi shining brightly in gamma rays at extremely high energy. The Gamma rays emanate from protons that are accelerated to very high energies in the shock front following the explosion. This suggests that novae are also a...
Giant stars undergo dramatic weight loss program
Apr 14, 2022 (Nanowerk News) There are millions of ‘red giant’ stars found in our galaxy. These cool and luminous objects are what our Sun will become in four billion years. For some time, astronomers have predicted the existence of slimmer red giants. After finding a smattering of them, the...
Predicting the most stable boron nitride structure with quantum simulations
Apr 14, 2022 (Nanowerk News) Boron nitride (BN) is a versatile material with applications in a variety of engineering and scientific fields. This is largely due to an interesting property of BN called “polymorphism,” characterized by the ability to crystallize into more than one type of structure. This generally occurs...
Electrostatic influences the movement of drops on surfaces
Apr 14, 2022 (Nanowerk News) Something as simple as the motion of water drops on surfaces should actually be understood - one would think. In fact there are still numerous unanswered questions about the forces acting on a sliding droplet. A team of researchers from the Max Planck Institute for...
First hybrid quantum bit based on topological insulators
Apr 14, 2022 (Nanowerk News) With their superior properties, topological qubits could help achieve a breakthrough in the development of a quantum computer designed for universal applications. So far, no one has yet succeeded in unambiguously demonstrating a quantum bit, or qubit for short, of this kind in a lab....
Optimizing silicon structure to reduce reflection
Apr 14, 2022 (Nanowerk News) Perhaps the most significant source of untapped renewable energy is, unsurprisingly, the Sun. It is little wonder that much of the focus of renewable energy research focuses on solar power. A new paper published in EPJ D ("Optimization of porous silicon structure as antireflective material")...
Golden wedding for molecules
Apr 14, 2022 (Nanowerk News) Chemical syntheses in liquids and gases take place in three-dimensional space. Random collisions between molecules have to result in something new in an extremely short time. But there is another way: on a gold surface under ultrahigh vacuum conditions, molecules lying still next to each...
