Oct. 7, 2021 —第一次,研究人员一直在帽ture images providing unprecedented details of how particles behave in a liquid suspension when the phenomenon known as shear thickening takes place. ...
Nov. 1, 2022 —The destruction of red blood cells, or mechanical hemolysis, is an inevitable complication of interventional devices, so scientists want to gain a better understanding of the phenomenon. Researchers ...
Oct. 11, 2022 —Researchers have shown that, for amorphous materials, cyclic material fatigue can begin to fracture at the same level of stress as fractures due to constant loading. By using computer simulations, ...
Sep. 22, 2022 —Chemists and physicists shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how and ...
Sep. 27, 2021 —Living or biological systems cannot be easily understood using the standard laws of physics, such as thermodynamics, as scientists would for gases, liquids or solids. Living systems are active, ...
Aug. 14, 2020 —Researchers using a high-speed camera have captured the moments a fluid reacts like a solid, through a new method of fluid observation under pressurized conditions. They examined fluids that have a ...
Nov. 3, 2022 —Chemists and engineers have discovered a fundamental friction law that is leading to a deeper understanding of energy dissipation in friction and the design of two-dimensional materials capable of ...
Aug. 28, 2020 —Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the ...
May 10, 2022 —Scientists describe their work on an at-home study of rheology, which is used to study the way non-Newtonian liquids or semisolid substances flow. The projects assigned to students had two parts: ...
Oct. 27, 2022 —Inefficient fluid machinery used in the energy and transportation sector are responsible for greenhouse gas emissions and the resulting global warming. To improve efficiency, it is necessary to ...
