The effect of molecular shape on the orientational structure and dynamics of propane, acetonitrile, acetaldehyde and acetone in ZSM-5 is studied by means of probing the differences in the orientational distribution of molecules in the ZSM-5 channels, and extracting time scales of the decay of ...
The concept of free volume is used to describe self-diffusion in liquids. It is found that for different organic liquids (including chloroform, carbon tetrachloride, p-xylene, o-xylene, toluene, n-hexane, n-heptane, acetone etc.), straight lines are obtained by plotting ln (Dii/RT) against...
we first sought to crystallize VenA in its substrate-free form. However, we did not obtain any crystals of the wild-type VenA (VenAWT) and supposed that theN-terminal flexible loop region (1-15 aa) might prevent the protein crystallization. Thus, the truncated form VenAΔ1-15with theN...
Inter-tissue interaction is fundamental to multicellularity. Although the basement membrane (BM) is located at tissue interfaces, its mode of action in inter-tissue interactions remains poorly understood, mainly because the molecular and structural details of the BM at distinct inter-tissue interfaces r...
A new series of imidazothiazole derivatives bearing thiazolidinone moiety (4a-gand5a-d) were designed, synthesized and evaluated for potential epidermal growth factor receptor (EGFR) kinase inhibition, anticancer and anti-inflammatory activity, cardiomyopathy toxicity and hepatotoxicity. Compound4cinhibited...
Polylactones blended with a polyether and then shaped are leached with aqueous solution of an organic solvent such as alcohol or acetone to elute selectively the polyether and form interconnected pores within the shaped polylactone. The ... S Anton - EP 被引量: 113发表: 1987年 Predicting gas...
The solvation dynamics of molecular probes is studied by broad-band fluorescence upconversion. The time-dependent position of the S1 → S0 emission band or of a vibronic line shape is measured with ~80 fs, 10 cm(-1) resolution. Polar solutes in acetonitrile and acetone, when excited into S1...
Chlorophyll concentration was determined spectroscopically using UV300 spectrophotometer (Spectronic Unicam, UK) in 80% (v/v) acetone according to [46]. Room temperature absorption spectra were recorded using Shimadzu UV-2600 spectrometer. For measurements of whole cells, the instrument was equipped wit...
(C10H8)—the prototype PAH carrying two fused benzene rings. The reaction is enabled by the methyl radical—formed via pyrolysis of acetone ((CH3)2CO)—with the 1-indenyl radical—generated via pyrolysis of 1-bromoindene (C9H7Br)—in a chemical micro reactor19to form naphthalene (C10H8)...
Arranging molecules into highly symmetric, topological crystal structures has been recognized as the best approach to functionalize electronic properties in molecular crystals, where the constituent molecules have been assumed to be rigid in shape. Here,
