Hybrid Quatsome‐Encapsulated Silver Nanoparticles as Stable Plasmonic Substrates for Surface‐Enhanced Raman Scattering

Journal of Raman Spectroscopy, EarlyView.
In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

Study on the vibration characteristic of crankshaft of single cylinder compressor based on crosshead settlement

Jixie qiangdu
The acceleration of the reciprocating parts of the compressor with the crosshead settlement fluctuates violently, and the comprehensive piston force becomes larger, which leads to the increase of the vibration amplitude of the crankshaft and the ...

Raman Bands of Malto‐ and Isomalto‐Oligosaccharides as Models for Starch

Journal of Raman Spectroscopy, EarlyView.
The present study measured Raman spectra of malto‐ and isomalto‐oligosaccharides with various degree of polymerization as models for starch. The data suggest that malto‐oligosaccharides with degree of polymerization ≥ 5 exhibit Raman bands similar to those of starch.

Chemical Kinetics of 2‐, 4‐, and 2,4‐Seleno‐Uracils at Low Temperatures: Tautomerizations and Rotamerizations on Inert Matrices

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT In the interstellar medium, chemical reactions proceed under conditions vastly different to those on Earth; these include extremely low temperatures and densities and take place in the gas phase and on water–ice grains. Understanding the energetics and more importantly the kinetics of such reactions is of relevance to the consequences on how ...

Cis–Trans Rotational Isomerism of Formic Acid, Sulfur, and Selenium Analogues and Their Dimers: Chemical Kinetics Under Interstellar Conditions

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT We present chemical kinetic rate constants for the cis to trans isomerisation or rotamerization of monomeric seleno‐, thio‐, and formic acids and that of three of their dimeric species, based on variational transition state theory and multidimensional tunneling calculations in the gas‐phase, from 10 K to 300 K. These provide, firstly, reliable
