4+ hour, 50+ min ago   (720+ words) Every year, roughly 2.3 million tons of flame retardants are applied worldwide, and demand keeps climbing, especially in construction. Most are made from petroleum, mined minerals, or halogenated chemistry that works well in fires but lingers in the environment and raises…...

53+ min ago   (610+ words) Yeast and gelatine could be used to create a sticky building material like concrete for constructing human habitats on Mars. How can frozen fruit help us build human habitats on Mars? Maybe not directly, but frozen fruit has sparked a…...

47+ 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…...

9+ min ago   (55+ words) Dental implants have become one of the most predictable long-term solutions for tooth replacement, yet their success hinges on a deceptively simple biological event: the direct, functional connection between the implant surface and the surrounding jawbone, known as osseointegration. Titanium,…...

9+ min ago   (718+ words) Slaughterhouses are among the most difficult facilities to keep environmentally clean. Every carcass processed leaves behind a wastewater stream loaded with blood proteins, fats, oils and grease, suspended solids, and an enormous chemical oxygen demand that can overwhelm conventional treatment…...

9+ min ago   (80+ words) A team of researchers at Quaid-i-Azam University in Islamabad has shown that an ordinary kitchen staple, corn starch, can be transformed into a surprisingly capable solid electrolyte for lithium-ion batteries when it is combined with the right additives. In work…...

4+ hour, 56+ 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....

1+ hour, 28+ min ago   (489+ words) Tin halide perovskites have long been the tantalizing alternative to lead-based perovskites in next-generation solar cells. They offer a narrower bandgap that is ideal for harvesting more of the solar spectrum, and they replace toxic lead with an environmentally friendlier…...

1+ hour, 42+ 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…...

2+ hour, 6+ 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…...
