Spectrophotometer standardization in UV-Vis spectral region
Journal of Measurement Science and Instrumentation, 2016 Ultraviolet-visible（UV-Vis）spectrophotometry is commonly used in analytical laboratories for qualitative and quantitative analyses.To make the data obtained reliable,an experimental instrument must be calibrated.National Institute for Standards（NIS）in ...

Thermal atmospheric models [PDF]
The static thermal atmosphere is described and its predictions are compared to observations both to test the validity of the classic assumptions and to distinguish and describe those spectral features with diagnostic ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Graphite nanofluids were stabilized using a mixed SDS/Tween 80 surfactant system. The optimized formulation exhibited enhanced colloidal stability, red‐shifted UV–Vis absorption, and improved photothermal conversion under solar irradiation. Achieving stable dispersion of graphite flakes (GFs) in aqueous media remains a critical challenge in developing ...

Antibacterial Activity of Heteropolytungstates Against Proteus mirabilis
European Journal of Inorganic Chemistry, EarlyView.We investigated the in vitro antibacterial activity of several heteropolytungstates against P. mirabilis, a drug‐resistant pathogen. All tested polyanions inhibited bacterial growth, with the Preyssler–Pope–Jeannin polyanion P5W30 exhibiting the highest activity (MIC = 0.78 mg/mL).

Correlated Ground-based and IUE Observations [PDF]
The value of coordination among different observers particularly, those working in different wavelength regions is highlighted. This coordination is more important among observers of comets than among observers of almost any other class of astronomical ...

ELECTROPHORESIS, EarlyView.A validated RP‐HPLC–UV method was successfully applied for amoxicillin determination in gummy tablets. The method is useful for an accurate amoxicillin content determination in paediatric gummies and was applied to study the stability profile of the drug, evaluated over 6 months under storage conditions.
