Affordable Materials Turn Waste Carbon into High-Energy Compounds

Carbon Capture, Material & Energy / Valeriano Ndeyi

Converting waste carbon into valuable products is essential for sustainable manufacturing. We can recycle carbon dioxide into carbon monoxide and then convert it into energy-dense compounds using electricity. However, current systems rely on anion exchange membranes that degrade over time when exposed to organic substances, reducing their overall efficiency. Low-Cost Diaphragms Offer Efficient Alternative for

Scientists Develop Transparent Solar Windows Using Liquid Crystals

Material & Energy, Nanotechnology / Jorge Paka

A Nanjing University team developed a transparent solar concentrator that coats ordinary window glass. The device employs cholesteric liquid crystal (CLC) multilayers with submicron-scale periodic structures to function as a diffractive solar concentrator (CUSC). It channels sunlight toward the window’s edges, where photovoltaic cells capture the energy. The findings were published in PhotoniX. Next-Gen Solar

Nuclear Waste Could Become a Source of Tritium for Fusion Power

Material & Energy, Nuclear & Particles / Samilton Santos

A looming shortage of fuel for nuclear fusion may have an unexpected fix. A physicist at Los Alamos National Laboratory (LANL) suggests that tritium for fusion reactors could be generated using nuclear waste left over from fission plants. If fusion energy becomes practical, it could revolutionize power production, delivering virtually limitless electricity on demand. Yet,

An Artificial Tongue That Learns Flavors

Material Technology, Science / Samilton Santos

Machines have long excelled at replicating sight and sound, but taste has remained much harder to capture in digital form. While previous efforts have produced artificial tongues specialized for sweetness, wine, or whisky, researchers in Beijing have now created a more versatile graphene oxide-based “tongue” that not only detects chemicals but also learns to recognize
