- A graphene addition for enhancing the critical current density of Bi-2223 superconductors 17/10/2023 Superconductors are materials that offer zero electric resistance to the flow of current on being cooled down below a certain critical temperature. Typically, superconductors have a very low critical temperature, close to absolute zero. However, a class of superconductors, known as high-temperature superconductors (HTS) have a critical temperature above 77 Kelvin, the boiling point of liquid nitrogen. They have been extensively used for the development of superconducting devices in many industries.
- Amazing New Material Contains an Extremely Rare Kind of Gold 12/10/2023 Thanks in part to the atom's size, a charged variation of gold called Au2+ isn't commonly found in nature.
- Ribbons of Graphene Push the Material’s Potential 10/10/2023 A new technique developed at Columbia offers a systematic evaluation of twist angle and strain in layered 2D materials.
- One-atom-thick ribbons could improve batteries, solar cells and sensors 05/10/2023 Researchers at UCL have created one-atom-thick ribbons made of phosphorus alloyed with arsenic that could dramatically improve the efficiency of devices such as batteries, supercapacitors and solar cells.
- Research team synchronizes single photons using an atomic quantum memory 03/10/2023 A long-standing challenge in the field of quantum physics is the efficient synchronization of individual and independently generated photons (i.e., light particles). Realizing this would have crucial implications for quantum information processing that relies on interactions between multiple photons.
- Novel filter uses carbon nanotubes to create new paradigm for dialysis membranes 28/09/2023 A collaborative team has developed a new type of filter for kidney dialysis machines that can clean the blood more efficiently and improve patient care. Piran Kidambi, assistant professor of chemical and biomolecular engineering, led the team, which included William Fissell, associate professor of nephrology and hypertension at Vanderbilt University Medical Center, Shuvo Roy, professor of bioengineering at University of California, San Francisco, and Francesco Fornasiero, biosciences and biotechnology staff scientist at Lawrence Livermore National Lab.
- Technique for 3D printing metals at the nanoscale reveals surprise benefit 26/09/2023 Late last year, Caltech researchers revealed that they had developed a new fabrication technique for printing microsized metal parts containing features about as thick as three or four sheets of paper.
- Atomic-scale spin-optical laser: New horizon of optoelectronic devices 21/09/2023 Researchers have pushed the limits of the possible in the field of atomic-scale spin-optics, creating a spin-optical laser from monolayer-integrated spin-valley microcavities without requiring magnetic fields or cryogenic temperatures.
- Copper-infused nanocrystals boost infrared light conversion 19/09/2023 Sunlight is an inexhaustible source of energy, and utilizing sunlight to generate electricity is one of the cornerstones of renewable energy. More than 40% of the sunlight that falls on Earth is in the infrared, visible and ultraviolet spectra; however, current solar technology utilizes primarily visible and ultraviolet rays. Technology to utilize the full spectrum of solar radiation—called all-solar utilization—is still in its infancy.
