DGIST Photocatalyst Boosts CO₂-to-Methane Output 200-Fold
2+ hour, 12+ min ago (244+ words) Wollongong-based online news outlet covering Australia and beyond. If you have anything newsworthy - a story, video or picture to share with us, please email us. □ To improve carbon dioxide conversion efficiency, the research team focused on MXene, a two-dimensional nanomaterial…...
IISc closer to converting carbon dioxide into methanol-like fuel
2+ hour, 53+ min ago (267+ words) BENGALURU: Researchers at the Indian Institute of Science (IISc) are reportedly close to figuring out a way to convert carbon dioxide (CO2) into fuel substances, akin to methanol. They have developed a data-driven computational framework that would help scientists map nearly…...
Overcoming MXene’s water stability challenge: DGIST develops photocatalyst that boosts CO₂-to-methane production performance 200-fold
4+ hour, 8+ min ago (169+ words) Asia Research News | □ To improve carbon dioxide conversion efficiency, the research team focused on MXene, a two-dimensional nanomaterial with excellent electrical conductivity. However, MXene has the limitation of being easily oxidized when exposed to water and oxygen, resulting in degraded…...
Cobalt Catalyst Delivers 99% Yield Without Expensive Precious Metals
4+ hour, 43+ min ago (425+ words) A cobalt catalyst may offer a more sustainable route to valuable chemical transformations when its oxidation state is carefully controlled. A cobalt catalyst made from an abundant metal converted more than 99% of pyridine into the desired chemical product under ambient…...
Overfermented cocoa beans can smell smoky without any smoke at all
38+ min ago (617+ words) Researchers at the Leibniz Institute for Food Systems Biology in Munich have shown that overfermentation of cocoa beans produces smoky, leathery, and cheesy off-flavor compounds at concentrations similar to those caused by wood smoke contamination, meaning smoky aromas in cocoa…...
Michigan Farmer Used a 10-Kilogram Meteorite as a Barn Doorstop for Decades
3+ hour, 53+ min ago (759+ words) A 10.22-kilogram (22.5-pound) rock spent decades propping open a barn door on a Michigan farm before scientists determined that it was an iron meteorite from space. The reported fall was never independently confirmed, so the Meteoritical Bulletin classifies Edmore as…...

3+ hour, 49+ min ago (390+ words) In a recent paper (1), you discuss utilizing laser ablation-spark discharge-optical emission spectroscopy (LA-SD-OES) and laser-induced breakdown spectroscopy (LIBS) to overcome the matrix effect in the elemental analysis of steel. Why is the elemental analysis of steel important and what are…...
Three-Dimensional Printing and the Art of Making Small Working Prototype Spectrometers
3+ hour, 46+ min ago (130+ words) Again, in this case, the 3D printing provided a testing platform that enabled the overall measurement concept to be evaluated. My background and training were in analytical chemistry, and over time became focused on spectroscopy. However, in the 1980s I started the…...
Vanishing Spectrometers: How Near-Infrared Instrumentation Got Small, Smart, and Everywhere
1+ hour, 39+ min ago (802+ words) The bulky bench-top NIR spectrometer is quietly being dismantled and rebuilt as a wafer-scale photonic chip, a self-calibrating algorithm, and a sensor small enough to ride in a shirt pocket. What once demanded a grating, a moving mirror, and a…...
