Mar 08, 2024 (Nanowerk News) Transition metal selenides have been considered to be a good choice for electrocatalytic water splitting. In addition, metal-organic frameworks (MOFs) have been used to make catalysts with good electrocatalytic capabilities. Traditionally, the MOF-derived selenides are produced via the self-sacrificing MOF template methods. However, this strategy...
Bioresorbable multilayer films enable long-lasting bioelectronic implants
Mar 08, 2024 (Nanowerk Spotlight) Imagine a tiny bioelectronic device, implanted beneath your skin, that could continuously monitor your vital signs, precisely deliver drugs, or even stimulate your muscles and nerves to treat a variety of conditions. Now imagine if, after a pre-programmed period of time, this device would simply...
Pushing the boundary on ultralow frequency gravitational waves
Mar 08, 2024 (Nanowerk News) A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, the heaviest objects in the universe. The method can detect gravitational waves that...
Tiny wireless light bulbs for biomedical applications
Mar 08, 2024 (Nanowerk News) A research team from the University of St Andrews and the University of Cologne has developed a new wireless light source that might one day make it possible to 'illuminate' the human body from the inside. Such light sources could enable novel, minimally invasive means...
Researchers develop artificial building blocks of life
Mar 08, 2024 (Nanowerk News) For the first time, scientists from the University of Cologne (UoC) have developed artificial nucleotides, the building blocks of DNA, with several additional properties in the laboratory. They could be used as artificial nucleic acids for therapeutic applications. DNA carries the genetic information of all...
Physics-based predictive tool will speed up battery and superconductor research
Mar 08, 2024 (Nanowerk News) From lithium-ion batteries to next-generation superconductors, the functionality of many modern, advanced technologies depends on the physical property known as intercalation. Unfortunately, it's difficult to identify in advance which of the many possible intercalated materials are stable, which necessitates a lot of trial-and-error lab work...
Deciphering catalysts: Unveiling structure-activity correlations
Mar 08, 2024 (Nanowerk News) In a new step towards combating climate change and transitioning to sustainable solutions, a group of researchers has developed a research paradigm that makes it easier to decipher the relationship between catalyst structures and their reactions. Details of the researchers' breakthrough were published in the...
Completely recycled viscose for the first time
Mar 06, 2024 (Nanowerk News) At present, viscose textiles are made of biomass from the forest, and there is no such thing as fully recycled viscose. Researchers at Lund University in Sweden have now succeeded in making new viscose – from worn-out cotton sheets. The research has been published in...
