An organic-inorganic hybridization strategy has been proposed to synthesize polymerizable lipid-based materials for the creation of highly stable lipid-mimetic nanostructures. We employ atomic force microscopy (AFM) to analyze the surface morphology and mechanical property of electrospun cholesteryl-succinyl silane (CSS)...

Engineering the work function of buckled boron α-sheet by lithium adsorption: a first-principles investigation.

Anal Bioanal Chem. 2015 Nov;407(29):8765-71. doi: 10.1007/s00216-015-9035-1. Epub 2015 Oct 14.

In this paper, the dissolution process of fully hydrolyzed polyvinyl alcohol (PVA) was investigated by temperature-dependent Fourier transform infrared spectroscopy (FTIR) combined with moving-window two-dimensional (MW2D) correlation infrared spectroscopy (IR). The results show that the FTIR spectra of PVA...
