The glassy gels can also self-heal – a cut or break can be repaired by applying heat, which makes molecules on the broken edges reconnect. Richard Hoogenboom at Ghent University in Belgium says this could make them useful in some instances when conventional plastics are used, but the for...
What that does, is burn the polymer away, and fuse the silicon nano particles together, while maintaining the structure of pores. 这种方法所做的是:燃烧聚合物,把硅纳米粒子融合在一起,并且同时保持孔结构。 But that's possible only on materials that can withstand high heat. 但是,这种方法只能用于...
Down at the smallest of scales, smaller even than molecules, smaller than atoms, we get to a place called the quantum foam. This is where wormholes exist. Tiny tunnels or shortcuts through space and time constantly form, disappear, and reform within this quantum world. And they actually link...
There is clear evidence that the oceans are warming due to anthropogenic climate change, and the northeastern coast of USA contains some of the fastest war
It can also occur at a molecular level, due to changes in the orientation of electrically polar molecules in response to an applied field, or through bending & stretching of the bonds between atoms within a molecule, very much like the material in a mechanical spring is bent or stretched. ...

Cosmic ray particles and ultraviolet light “not only can heat the ices and make reactions happen that way,” said Perry Gerakines of the Astrochemistry Lab at NASA’s Goddard Space Flight Center, “they break molecules apart and form radicals that are more reactive.” With methanol as a ...
Cell-free transcription and translation systems are a model for recapitulating endogenous cell processes (i.e., transcription of DNA and translation of RNA to proteins) in a modular, bottom-up fashion. By adding specific DNA templates and finite concentrations of small molecules, like ATP, NTPs...
A heat sink is an electronic device made of good thermal conducting material and usually attached to an electronic device to dissipate the unwanted heat. It is used to cool the circuit components by dissipating the excess heat to prevent overheating, premature failure, and improve the reliability ...
heat, radiation, desiccation, pH extremes, and toxic chemicals (Setlow, 2000). The dormant spores also monitors the environment around theirs, and when conditions are again favorable (presence of germinants as nutrients such as amino acids, sugars, purine nucleosides, or other agents as lysozyme...
