Kenneth G. Libbrecht. The surface diffusion length of water molecules on faceted ice: A reanalysis of `roles of surface/volume diffusion in the growth kinetics of elementary spiral steps on ice basal faces grown from water vapor', by asakawa et al. arXiv:, (1509.06609), 2015....
7.It can be inferred from paragraph 4 that the length of time a given molecule of water remains in a lake A. depends entirely upon the average speed of a lake' s currents B. can be measured by the volume of the lake alone C. can be greater or lesser than the residence time ...
句子 The residence time is the average length of time that any particular molecule of water remains in the lake, and it is calculated by dividing the volume of water in the lake by the rate at which water leaves the lake. 问题 句子分析(俗称“长难句分析”)是训练提高基础阅读能力的有效手段...
We used two dif- ferent probes, one with the size of a water molecule (radius 0.12 nm) and one with the size of a xenon atom (radius 0.22 nm). While the first NMR data set only contains coordinates of the folded core part of the structure (amino acid 125 to 228), the ...
A mean length of travel, characteristic of a particular motion, over which an eddy maintains its identity; it is analogous to the mean free path of a molecule; physically, the idea implies that mixing occurs by discontinuous steps, that fluctuations which arise as eddies with different characteri...
The dimensions used are the molecular volume, calculated by integrating the electronic density, and the smallest and largest dimensions of a box containing the molecule. There are two adjustable parameters in these calculations: the electronic density threshold, and the grid size. Values for these ...
A water molecule com- pletes the octahedral Fe(III) coordination (with good density in only one of the three independent molecules in the asymmetric unit, Fig. 5). Intrinsic fluorescence quenching. The affinities of CeuE for the four Fe-n-Lic complexes were quantified using intrinsic ...
In the past 20 years, single-molecule pulling experiments of biomolecules under mechanical forces provided a wealth of information about the mechanical properties of such molecules, and the structural changes that may happen under stress in mechanical proteins, as well as shedding light upon many rece...
Activities of ATP binding cassette (ABC) proteins are regulated by multiple mechanisms, including protein interactions, phosphorylation, proteolytic processing, and/or oligomerization of the ABC protein itself. Here we present the structure of yeast cadm
Using a small molecule that non-covalently crosslinks thymine residues, we show that this dynamic morphology can be “frozen” into stable fibers that retain low dispersity. This work defines a new class of sequence-defined DNA oligomers called ‘curlamers’, whose folding behavior is precisely ...
