Dec 17, 2022 (Nanowerk News) A team of engineers at the University of California San Diego has developed an electronic patch that can monitor biomolecules in deep tissues, including hemoglobin. This gives medical professionals unprecedented access to crucial information that could help spot life-threatening conditions such as malignant tumors, organ...
Biological cell plasma membranes inspire novel separator for a practical lithium-sulfur battery
Dec 16, 2022 (Nanowerk Spotlight) Lithium-sulfur (Li-S) batteries are compelling candidates for next-generation energy storage devices – sulfur is abundant, low-cost and sustainable. Thanks to the multi-step reactions of sulfur, it also has a greater theoretical energy density than found in current Li-ion battery technology. However, the reaction intermediates, called...
Success in high-speed, high-sensitivity terahertz detection using a graphene transistor
Dec 16, 2022 (Nanowerk News) On the electromagnetic spectrum, which comprises everything from radio waves to X-rays and gamma rays, there exists a deadzone where conventional electronic devices can hardly operate. This deadzone is occupied by terahertz waves. With wavelengths of approximately 10 micrometers to 1 millimeter, terahertz waves are...
Astronomers find that two exoplanets may be mostly water
Dec 16, 2022 (Nanowerk News) A team led by Université de Montréal astronomers has found evidence that two exoplanets orbiting a red dwarf star are “water worlds,” planets where water makes up a large fraction of the volume. These worlds, located in a planetary system 218 light-years away in the...
Astronomers may have uncovered how galaxies change their shape
Dec 16, 2022 (Nanowerk News) Researchers may have answered a decades-old question about galaxy evolution, leveraging the power of artificial intelligence (AI) to accelerate their research. Ever since the Hubble Sequence, that classifies galaxy morphologies, was invented in 1926, astronomers have been refining our understanding of galaxy evolution and morphology...
The discovery of interfacial ferromagnetism in 2D antiferromagnet heterostructures
Dec 16, 2022 (Nanowerk News) Van der Waals (vdW) magnets and their heterostructures have emerged as new platforms to explore exotic magnetic orders and quantum phenomena. Yet combining two different magnetic orders and investigating the magnetic proximity at the interface remains largely unexplored. Doing so could enable the modulation of...
New experimental setup achieves unprecedented accuracy in strain engineering of 2D materials
A new motorized three-point-bending apparatus has been developed that is capable of automating strain engineering experiments on two-dimensional (2D) materials. The setup can be used to apply precise, uniform strain to 2D materials such as MoS2, allowing researchers to study the effects of strain on the electrical and optical properties...
Dynamical fractal discovered in clean magnetic crystal
Dec 16, 2022 (Nanowerk News) The nature and properties of materials depend strongly on dimension. Imagine how different life in a one-dimensional or two-dimensional world would be from the three dimensions we’re commonly accustomed to. With this in mind, it is perhaps not surprising that fractals – objects with fractional dimension –...
An all-optical approach to pumping chip-based nanolasers
Dec 16, 2022 (Nanowerk News) Researchers have developed a new all-optical method for driving multiple highly dense nanolaser arrays. The approach could enable chip-based optical communication links that process and move data faster than today’s electronic-based devices. “The development of optical interconnects equipped with high-density nanolasers would improve information processing...
