Upcycling leftover cardboard to make a new type of foam packaging      (via sciencedaily.com)     Original source 

With the holiday season in full swing, gifts of all shapes and sizes are being shipped around the world. But all that packaging generates lots of waste, including cardboard boxes and plastic-based foam cushioning. Rather than discard those boxes, researchers have developed a cushioning foam from cardboard waste. Their upcycled material was stronger and more insulating than traditional, plastic foam-based cushioning.

Researchers find way to weld metal foam without melting its bubbles      (via sciencedaily.com)     Original source 

Researchers have identified a welding technique that can be used to join composite metal foam (CMF) components together without impairing the properties that make CMF desirable. CMFs hold promise for a wide array of applications because the pockets of air they contain make them light, strong and effective at insulating against high temperatures.

Towards next-generation nanocatalysts to revolutionize active electron transfer      (via sciencedaily.com)     Original source 

Over the years, scientists have proposed many novel molecular systems for photoinduced electron transfer. Researchers have now developed a copolymer-conjugated nanocatalytic system that can drive efficient photoinduced electron transfer. They employed a temperature-responsive ternary random copolymer and coupled it to platinum nanoparticles. By enabling dynamic electron transfer and driving photoinduced hydrogen generation, this innovation can have far-reaching implications for artificial photosynthesis, electrochemical reactions, macromolecular recognition, and bio-inspired soft materials.

Ultra-hard material to rival diamond discovered      (via sciencedaily.com)     Original source 

Scientists have solved a decades-long puzzle and unveiled a near unbreakable substance that could rival diamond, as the hardest material on earth, a study says. Researchers found that when carbon and nitrogen precursors were subjected to extreme heat and pressure, the resulting materials -- known as carbon nitrides -- were tougher than cubic boron nitride, the second hardest material after diamond.

New conductive, cotton-based fiber developed for smart textiles      (via sciencedaily.com)     Original source 

A single strand of newly developed fiber has the flexibility of cotton and the electric conductivity of the polymer, polyaniline. The new material has shown good potential for wearable e-textiles. The researchers tested the fibers with a system that powered an LED light and another that sensed ammonia gas. While intrinsically conductive, polyaniline is brittle and by itself, cannot be made into a fiber for textiles. To solve this, the researchers dissolved cotton cellulose from recycled t-shirts into a solution and the conductive polymer into another separate solution.
