根据句意“一个水分子是由两个氢原子和一个氧原子组成的”,“由...组成”可译为bemadeupof,也可译为consistof,consistof 不用于被动语态,根据原句中的is可知应用一般现在时态,主语A moleculeofwater是单数形式,故谓语动词应用第三人称单数形式,故填consistsof。 反馈 ...
A model using the electrostatic image force and the harmonic restoring force has been adapted to find the equilibrium structure of a chemisorbed water molecule on a metal surface. An estimate of the maximum possible increase in the HOH interbond angle upon chemisorption due to image forces is ...
Serine-based β-lactamases of Class A, C and D all rely on a key water molecule to hydrolyze and inactivate β-lactam antibiotics. This process involves two conserved catalytic steps. In the first acylation step, the β-lactam antibiotic forms an acyl-enzyme intermediate (ES*) with the catal...
Intermolecular hydrogen bonds impede long-range (anti-)ferroelectric order of water. We confine H2O molecules in nanosized cages formed by ions of a dielectric crystal. Arranging them in channels at a distance of ~5 Å with an interchannel separation of ~10 Å prevents the formation of ...
I describe the structure and diffusion of a single water molecule isolated on a Cu(110) surface in this chapter. The monomeric adsorption of water molecules can be realized at low temperature (<20K). The adsorption structure is determined with the help of DFT calculations. A water molecule che...

aWe can therefore approximately find the volume of one molecule by dividing the volume of a mole of a liquid, for example, water, by the number of molecules in a mole N . 因此我们在痣N.可以通过划分液体,例如,水的痣的容量近似地发现一个分子的容量,由分子的数量。[translate] ...
Tissue-like cultured meats of some livestock have successfully been established by different approaches. However, the production of a structure similar to fish fillets is still challenging. Here, we develop tissue-like cultured fish fillets by assembly o

throughout biological systems. "If you know the conducting properties of the two forms for a single water molecule, then you can predict the conducting properties of a water chain," said Limin Xiang, a postdoctoral scholar at University of California, Berkeley, and the first author of the ...
