polympart: Scientists have developed a completely new soft-yet-strong, squishy materials that named Super Jelly that is capable of regain its authentic form after being run over by a automobile – or to make use of a extra pure instance, after being walked over by an elephant. Made up of 80 % water, the components of the fabric that are not water allow it to behave like an ultra-hard glass when it is compressed. Researchers suppose it is the primary time a mushy materials like this has proven such wonderful resistance to compression. And after additional growth, the ‘tremendous jelly’ may have a complete host of sensible purposes, the crew behind the fabric says – the whole lot from being utilized in mushy robotics to enhancing the flexibleness ...
polympart :A sugar-containing polymer coating could one day help repair artificial joint implants, like hip replacements, when they are damaged through wear and tear, according to new research. An international team of chemists and engineers, including Durham and York universities, UK, and Tsinghua University, China, has developed the technique for easily repairing low-friction surfaces. Taking their inspiration from the way cartilage works to lubricate joints in humans, the team has found that rings of sugar can help a polymer latch on to surfaces and repair damage. Publishing their findings in the journal Chem, they say their discovery could eventually be used in medical implants to extend the life-span of artificial joints. They hope ...
polympart :A triboelectric nanogenerator (TENG) is an energy-harvesting device that converts mechanical energy into electricity through contact separation or relative sliding movements of two opposite tribo-polar materials. Researchers from Inha University previously reported the first example of sulfur backbone polymer-based TENG. The surface of the sulfur copolymer film was directly fluorinated using toxic fluorine gas to enhance TENG performance. Sulfur and fluorine have higher electron affinity (EA) of –200 kJ/mol and –322 kJ/mol, respectively when compared to the EA of carbon (–122 kJ/mol). The fluorinated sulfur copolymer film can achieve a six-fold and three-fold increase in voltage and current in comparison with polytetrafluoroethylene (PTFE), ...
