To effectively replicate the movements of humans and animals, robots should integrate muscle-like structures. These artificial muscles should attain an optimal performance across all relevant actuation parameters, including ...
Protons (subatomic particles) can be transferred from the anode to the cathode through the ionomer membrane in polymer electrolyte fuel cells (PEFC). Scientists can extend proton pathways by impregnating the ionomer (type ...
(Phys.org)—Researchers have designed a thermal regulation textile that has a 55% greater cooling effect than cotton, which translates to cooler skin temperatures when wearing clothes made of the new fabric. The material ...
A small international team of soil and water ecosystem conservation specialists has found that biocrusts clinging to parts of the Great Wall of China have been serving to protect the famous structure from erosion. In their ...
To synthesize plastic, small monomer molecules need to be strung together like beads in a necklace, creating long polymer chains.
