Hydration and Intermolecular Interactions in Carboxylic Acids

Конденсированные среды и межфазные границы, 2020
At the moment, the most accurate and reliable information about intermolecular interactions in low-molecular compounds and their polymer analogues can be obtained by means of combined UV, visible, and IR spectroscopy.

UV-pump/UV-probe spectroscopy of N₂

Journal of Physics: Conference Series, 2020
Synopsis UV-pump / UV-probe photoelectron spectra of N2 are theoretically evaluated by solving the time-dependent Schrödinger equation in a basis of all-electron bound and continuum eigenstates provided by the XChem code.

The Use of Copper Ions and Tannic Acid to Enhance the UV Protection of Cotton Fabrics

Journal of Natural Fibers, 2022
An ultraviolet (UV)-protective cotton fabric has been developed by combining tannic acid and copper ions (TA-Cu) on cotton fabrics. The structure and properties of TA-Cu and cotton fabrics finished with TA-Cu were characterized by Fourier-transform ...

High‐Resolution UV Spectroscopy of Molecular Complexes [PDF]

Berichte der Bunsengesellschaft für physikalische Chemie, 1992
AbstractInformation on the structure, the rigidity and the intermolecular potential of molecular complexes is essential to our understanding of the physical and chemical properties of molecular complexes. In this work we would like to demonstrate that rotationally resolved UV spectroscopy provides precise new information on these topics. In particular,

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in
