Size effects can influence the cohesive energy as well as the activation energies of vacancy formation and diffusion of atoms in the nanoscale particles (Vanithakumari and Nanda, 2008). Phase transitions in aerosol systems with nanoscale particles (clusters) also depend on the nanoparticle size (Lev...
aWhen the mean-free path A of the gas molecules becomes comparable to the gap size 0,h e gas cannot be considered as a continuum and the exchan 当气体分子的无意味道路A变得可比较与空隙大小0时, h e气体不可能被考虑作为连续流和exchan[translate]...
in size意思是“在尺寸上”,一般用于在买东西的时候,或者讨论一件物品,通常都说尺寸号码多少,有没有这个号码的之类,这时用in size。而有时候可以单用size来编写句子,如果用in...size就是在…的尺寸的意思,这就是一个固定句子结构。例如:They differ in size but not in kind. 他们不同在...
We show that measured optical transmittance of an ultra thin gas depends on the detector size. To this end we conducted an experiment that compares transmittances measured in parallel with a pair of detectors with different diameters ranging from 2 to 20
The Chemistry of Fluorine-bearing Molecules in Diffuse and Dense Interstellar Gas Clouds large molecular fraction; at redshifts beyond ~0.3, HF is potentially detectable from ground-based submillimeter observatories in several atmospheric ...

Size-exclusion chromatography (SEC) has proved effective for the separation and analysis of mixtures of polymers. In this method the largest molecules emerge from the chromatographic column first, because they are unable to penetrate the porous matrix of the support. Smaller molecules appear later, ...
This will give the researchers an intuitive impression of the size and distribution of SAMOPs. Compared with BET adsorption experiments, geometric analysis can detect smaller voids because the probe size can be arbitrary and can be smaller than gas molecules (such as nitrogen and carbon dioxide)....
In both cases, the fluid inside the porous solid exchanges matter with a reservoir of gas that is at the same temperature and chemical potential and whose relative size can be varied, and the control parameter is the total number of molecules present in the porous sample and in the reservoir...
Moreover, blowing agent material also influences the size of pores. Some blowing agent materials, such as TiH2, produce extremely coarse pore structures, while others, such as CaCO3, can form small pore structures. CaCO3 powder reacts with Mg melt involving CO gas as the blowing agent, ...
The distribution and peak of HA molecular sizes are shifted toward HMW HA in NMR compared to GP The next step was to determine the distribution of sizes of HA molecules using SEC in the same tissues (NMR vs GP) and in the serum (NMR, GP, and mouse). ...
