Applied Sciences, Vol. 16, Pages 9077: Conditional Deep Convolutional GAN for the Design of High-Performance Periodic Absorber Metasurfaces
37+ 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…...
Electron-Deficient Bonds Drive Staged Magnetic Shifts in Vanadium Material
1+ hour, 32+ min ago (599+ words) Chemical bonds are usually treated as the fixed scaffolding of a material, the framework that determines how atoms sit relative to one another and how electrons move through the resulting structure. Yet in certain classes of matter, the bonds between…...
Caged Nickel Catalyst Turns Greenhouse Gases Into Syngas and Refuses to
1+ hour, 55+ 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…...
Tea-Grown Nickel Oxide Nanoparticles Turn Chitosan Films Into Tunable
2+ hour, 45+ 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…...
Machine Learning Meets X-Rays to Reveal the Hidden Architecture of Pea
3+ hour, 2+ min ago (95+ words) Every seed is a masterpiece of biological engineering, a compact package in which molecular order and cellular design are woven together to protect and nourish a future plant. For scientists trying to understand how crops such as the yellow pea…...
MXenes Emerge as Frontier Nanomaterials Powering Supercapacitors and Clean
3+ hour, 2+ 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…...
Spirocycle Turns Sulfur Into a Multicentred Catalyst Through Through-Space
3+ hour, 52+ min ago (614+ words) Chemists have long relied on a single trick to make the inert atoms of the p-block of the periodic table behave like reactive metals: bend them out of shape....
Chemists Program Alkenes With Switchable Radical and Organometallic Sorting
3+ hour, 52+ min ago (623+ words) Chemists at Wuhan University have unveiled a nickel-catalysed reaction that can build an impressive range of alkene architectures from the same simple set of starting materials, simply by changing the ligand on the catalyst....
Hollow Alumina Spheres Deliver Complete Conversion in Greener Diethyl
4+ hour, 31+ min ago (88+ words) Chemists at Shihezi University in China have shown that the shape of a catalyst can matter as much as its chemistry, reporting that hollow spherical alumina particles outperform conventional forms of the same material in a key industrial reaction. In…...
Engineered Bacterial Teams Turn Sunlight and CO2 Into 1-Butanol
5+ hour, 4+ min ago (350+ words) Scientists at Uppsala University have taken a significant step toward a long-sought goal in industrial biotechnology: using sunlight and carbon dioxide to feed engineered microbes that churn out valuable chemicals. In a study published in Applied Microbiology and Biotechnology, Stamatina…...
