Sustainable methane utilization technology via photocatalytic halogenation with alkali halides
Catalyst synthesis and characterization In this work, the Cu, which has been proven to play a critical role as active sites for methane activation on particulate methane monooxygenase in nature, is selected to dope TiO2 photocatalysts for methane halogenation15,22. The Cu-doped porous TiO2 nanostructures (denoted as X%Cu–TiO2, where X represents the molar percentage of Cu…

Are piezoelectrics good for generating electricity? Perhaps, but we must decide how to evaluate them
An artistic impression of electricity generation in a piezoelectric energy harvester made from piezoelectric nanofibers. Credit: Katharina Maisenbacher, Max Planck Institute for Polymer Research A ‘best practice’ protocol for researchers developing piezoelectric materials has been developed by scientists—a first in this cutting-edge field of technology. The protocol was developed by an… Continue Reading News Source:…

Magnetism fosters unusual electronic order in quantum material
Mar 13, 2023 (Nanowerk News) Physicists were surprised by the 2022 discovery that electrons in magnetic iron-germanium crystals could spontaneously and collectively organize their charges into a pattern featuring a standing wave. Magnetism also arises from the collective self-organization of electron spins into ordered patterns, and those patterns rarely coexist with the patterns that produce…

Scientists transform algae into unique functional perovskites with tunable properties — ScienceDaily
Perovskites are materials that are increasingly popular for a wide range of applications because of their remarkable electrical, optical, and photonic properties. Perovskite materials have the potential to revolutionize the fields of solar energy, sensing and detecting, photocatalysis, lasers, and others. The properties of perovskites can be tuned for specific applications by changing their chemical…

New research takes step towards 3D laser printed medical electronics
Mar 13, 2023 (Nanowerk News) A team of scientists, led by researchers at Lancaster University, have developed a method to 3D print flexible electronics using the conducting polymer polypyrrole, and they have shown that it is possible to directly print these electrical structures on or in living organisms (roundworms). Their findings are reported in a…

New proton hydration structure determined
The experiment: Infrared light excites protons in the water film, which move between the Ti3C2-MXene layers. Their oscillation patterns show that they behave differently than in a thicker film of water. Credit: M. Künsting /HZB MXenes are able to store large amounts of electrical energy like batteries and to charge and discharge rather quickly like…

Scientists determine new proton hydration structure
Mar 13, 2023 (Nanowerk News) MXenes are able to store large amounts of electrical energy like batteries and to charge and discharge rather quickly like a supercapacitor. They combine both talents and thus are a very interesting class of materials for energy storage. The material is structured like a kind of puff pastry, with the…

Scientists transform algae into unique functional perovskites with tunable properties
Mar 13, 2023 (Nanowerk News) Scientists have transformed single-cell algae into functional perovskite materials. The team led by scientists at the B CUBE – Center for Molecular Bioengineering at TU Dresden converted mineral shells of algae into lead halide perovskites with tunable physical properties. The new perovskites have unique nano-architectures unachievable by conventional synthetic production.…
