Highly time-resolved chemical speciation and source apportionment of organic aerosol components in Delhi, India, using extractive electrospray ionization mass spectrometry

Publikováno v: Atmospheric Chemistry and Physics, Vol 22, Pp 7739-7761 (2022)

In recent years, the Indian capital city of Delhi has been impacted by very high levels of air pollution, especially during winter. Comprehensive knowledge of the composition and sources of the organic aerosol (OA), which constitutes a substantial fr

Optical microscopy, DSC, and X-ray diffraction studies on octyl and decyl members of the homologous series 4(4'-n-alkoxybenzoyloxy)phenyl azo-4'-isoamyloxy benzene

Autor: P. R. Patel, S. Biswas, J. S. Dave, P. K. Mandal

Publikováno v: SPIE Proceedings.

Octyl and decyl members of the homologous series 4(4'-n-Alkoxybenzoyloxy)phenyl azo-4"-isoamyloxy benzene have been studied by optical microscopy, DSC and X-ray diffraction techniques. Transition temperatures of the compounds are determined by observ

Influence of Molecular Structure on Liquid Crystalline Properties and Phase Transitions in Mixed Liquid Crystals

Autor: J. S. Dave, K. L. Vasanth

Publikováno v: Molecular Crystals. 2:125-134

A number of binary systems comprising a liquid crystalline Schiff's base, viz. p-acetoxybenzal-p-phenetidine and a non-liquid crystalline Schiff's base are studied. In all these cases, the liquid phase, be it anisotropic or not, is a single homogeneo

Mesomorphic Behaviour of the Cholesteryl Esters-I: p-n-Alkoxybenzoates of Cholesterol

Autor: R. A. Vora, J. S. Dave

Publikováno v: Liquid Crystals and Ordered Fluids ISBN: 9781468482164

A homologous series of Cholesteryl p-n-alkoxybenzoates has been synthesised and its mesomorphic behaviour studied. All the members of the series are enantiotropic mesomorphic. The higher members starting with cholesteryl p-n-heptyloxybenzoate exhibit

METAL CHELATES OF αβ-DIOXIMINOACETOACETAMIDES

Autor: J. S. DAVE, A. M. TALATI

The dioximes, prepared from acetoacet(aryl) amides (wherearyl amide may be anilide. o-toluidide, o-chloramlide, p-phenetidide or 2:4-xylidide), have been used for the preparation of copper, nickel, cobalt, and palladium chelates. The magnetic suscept
