I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Soft robot actuators heal themselves” Series of protein-based artificial muscles, with performance exceeding that of biological muscle. Other soft robotic parts could include soft grippers and soft actuators. Credit: Demirel Lab, Penn State Repeated activity wears on soft robotic actuators, but these machine’s moving parts need to be reliable and easily fixed. Now a team…
“#Understanding of relaxor ferroelectric properties could lead to many advances” Chiral (mirror) molecules give relaxor ferroelectrics their amazing properties. Credit: MRI, Penn State A new fundamental understanding of polymeric relaxor ferroelectric behavior could lead to advances in flexible electronics, actuators and transducers, energy storage, piezoelectric sensors and electrocaloric cooling, according to a team of researchers…
“#Ion conducting polymer crucial to improving neuromorphic devices” Photograph of a neuromorphic device used in this study. Credit: Shunsuke Yamamoto “Neuromorphic” refers to mimicking the behavior of brain neural cells. When one speaks of neuromorphic computers, they are talking about making computers think and process more like human brains-operating at high-speed with low energy consumption….
“#Growing polymers with different lengths” Symbolic representation of how the dispersity of a plastic can be controlled by mixing two catalysts (paint tubes). Credit: Whitfield R et al, Chem, 2020 ETH researchers have developed a new method for producing polymers with different lengths. This paves the way for new classes of polymer materials to be…
“#Tiny pump builds polyrotaxanes with precision” Northwestern University researchers have developed the most precise way to build polyrotaxanes, a mechanically locked polymer for slide-ring gels, battery electrode materials and drug-delivery platforms. A necklace-like molecule made with rings threaded onto a polymer string, polyrotaxanes are notoriously difficult to construct. A new method from the laboratory of…
