The diffusion coefficients were calculated using Green-Kubo formula and Einstein relation. Relaxation of autocorrelation functions of nanotube velocity and angular velocity was systematically discussed for all cases. It is shown that this relaxation has two stages and the first stage is an exponential. ...
The maximum performance occurred at a specific frequency of the electric field. This specific frequency can be computed by an analytical formula for given materials and temperatures. Moreover, the results indicate that the length of the nanotube can affect the gas pumping. 展开 ...

5 Therefore, a first aspect of the present invention relates to a nanocapsuleformed by two parallel (metal) tetracarboxylated porphyrins of general formula (1)joined by four metal macrocyclic compounds of general formula (11) throughof an M-carboxylate bond, and counterions (X) in a number sui...
Then, we evaluate the conformational entropy of HP35 as a function of time via the following formula: \(S=-P{\text{ln}}P\), wherein P indicates the ratio of the residue numbers of α-helix of HP35 at each time point with respective to the one of HP35 original structure. As shown...

Flavors are considered among the most valuable ingredients in any formula. However, aromatic substances are volatile and can be lost during processing and storage. Thus, it is beneficial to develop strategies for their retention in formulations. The aim of the present study was to evaluate the abi...
As ks is readily determined from the vibrational frequency and the mass of the vibrating atoms, and De (with some adjustment for the zero point vibrational energy) is determined from chemical data about the bond strength, the parameter b can then be determined using the formula (Drexler, 1992...
