New process produces ordered semiconductor material at room temperature
Graphical summary. Credit: Nature Synthesis (2025). DOI: 10.1038/s44160-024-00717-z Scientists at the University of Twente have developed a method to create highly ordered semiconductor materials at room temperature. The UT study was published today in the journal Nature Synthesis. This breakthrough could improve the efficiency of optoelectronics by controlling the crystal structure and reducing the number of defects at the nanoscale.…

Space & Cosmos
Astronauts found that they were able to process some tasks more slowly in space, but they showed no signs of permanent cognitive decline.
Credit: CC0 Public Domain Staying in space puts extreme pressure on the human body. Astronauts’ bodies and brains are affected by radiation, changes in gravity, harsh working conditions, and sleep deprivation, all of which can impair cognitive function. At the same time, you have to perform complex tasks, and small mistakes can have catastrophic consequences. However, little is known about…

Biorefining process could allow pigs, chickens and fish to digest grass
Here, small fibrous residues are filtered from protein juice in a small laboratory. Credit: Stefan Adler Currently, grass is mainly used directly as feed for cattle and other ruminants. These animals have multicompartmental stomachs specialized for breaking down plant fibers. In the biorefining process, plant material is crudely processed in a screw press and valuable nutrients are released from the…

New process strengthens thermoplastic and polylactic acid blends
In nano-IR imaging, the layer structure of the pure PVDF/PLLA mixture (left) and the layer with SAD additive (right) can be clearly distinguished. Light and dark colors correspond to the PLLA and PVDF phases, respectively. Adding SAD reduces the domain size in two phases. Credit: Eindhoven University of Technology/HZB Bio-based thermoplastics are manufactured from renewable organic materials and can be…

Study shows self-assembly of light-absorbing chiral molecules facilitates singlet fission process
TEM image of aqueous NPs. a) Tc_NP, scale, 100 nm. b) Tc_R-NEA_NP, scale, 200 nm. c) High-resolution TEM of Tc_R-NEA_NPs, scale, 100 nm. Credit: Advanced Science (2024). DOI: 10.1002/advs.202405864 In organic molecules, an exciton is a pair of an electron (negative charge) and its hole (positive charge) bound to a particle. They are held together by Coulombic attraction and can…

Add visible light energy to your carbon dioxide recycling process and you get a two-for-one deal
New research from the University of Illinois captures energy from the visible light spectrum to enhance carbon dioxide recycling. Credit: National Science Foundation By combining visible light and electrochemistry, researchers accelerated the conversion of carbon dioxide into valuable products and stumbled upon a surprising discovery. The research team shows that visible light significantly improves an important chemical property called selectivity,…
