Applied Sciences, Vol. 16, Pages 9077: Conditional Deep Convolutional GAN for the Design of High-Performance Periodic Absorber Metasurfaces
29+ min ago (271+ words) This work presents a conditional deep convolutional generative adversarial network (CDCGAN) for the inverse design of high-absorptance periodic metasurfaces (MSs) with different geometries. The conditioning mechanism encodes geometric and spectral parameters. A key innovation is the inclusion of unit cells…...
In 1903, a mining engineer staked a claim on Arizona's Meteor Crater, convinced a fortune in iron lay beneath the floor, and spent 26 years drilling for a meteorite that had mostly vaporized on impact — his family still owns the crater today, and science later proved him right about everything except the treasure
4+ hour, 38+ min ago (26+ words) A wealthy engineer bet his fortune on a hole in the ground that science said was worthless, and spent three decades proving the experts catastrophically wrong....
Caged Nickel Catalyst Turns Greenhouse Gases Into Syngas and Refuses to
1+ hour, 48+ min ago (660+ words) Two of the most troublesome greenhouse gases, methane and carbon dioxide, can be forced to react with one another in a process known as dry reforming of methane, a reaction that converts both pollutants into valuable synthesis gas, a mixture…...
Green Solvents and Microwaves Unlock Antioxidant Treasures Hidden in
2+ hour, 30+ min ago (55+ words) Chemists in Pakistan have shown that the secret to extracting powerful antioxidant compounds from the leaves of the lemon-scented eucalyptus tree lies in matching the polarity of the solvent to the chemistry of the target molecules. In a study published…...
Tea-Grown Nickel Oxide Nanoparticles Turn Chitosan Films Into Tunable
2+ hour, 38+ min ago (617+ words) A team of materials scientists has shown that ordinary green tea can do far more than steep a soothing drink: its polyphenol-rich extract can grow phase-pure nickel oxide nanoparticles that, when embedded in a biodegradable chitosan matrix, transform a humble…...
Engineered Porous Carbon Traps Cancer-Causing Benzene From Air and
2+ hour, 41+ min ago (72+ words) Benzene is one of the most insidious chemicals that ordinary people encounter every day. The International Agency for Research on Cancer classifies it as a Group 1 human carcinogen, meaning there is established evidence that it causes cancer in humans, with…...
Spent Coffee Grounds Turned Into Carbon Dots That Boost Antibacterial Food
2+ hour, 41+ min ago (524+ words) Every year, the world brews billions of cups of coffee, and almost all of the spent grounds end up in landfills, where they slowly decompose and release methane....
Bubble Collapse and Hydrogen Peroxide Join Forces to Destroy Stubborn Dye
2+ hour, 55+ min ago (672+ words) Synthetic dyes are among the most stubborn pollutants humanity releases into rivers and groundwater, and azo dyes—the largest class, defined by their characteristic nitrogen–nitrogen double bond—account for an estimated 60 to 70 percent of global colorant production....
MXenes Emerge as Frontier Nanomaterials Powering Supercapacitors and Clean
2+ hour, 55+ min ago (79+ words) A sweeping review published in Discover Electrochemistry has consolidated more than a decade of progress on MXenes, a family of two-dimensional transition metal carbides, nitrides, and carbonitrides that many researchers now regard as the most versatile nanoarchitecture in modern energy…...
Weaker Water Bonds Boost Hydrogen Evolution on Titanium Dioxide
3+ hour, 15+ min ago (351+ words) Hydrogen produced by splitting water with sunlight has long been one of the most attractive goals in sustainable energy research, offering a clean fuel whose only byproduct when burned is water. Photocatalytic water splitting, in which semiconductor materials absorb light…...
