Positional Isomeric Effects on the Physicochemical Properties of Polymeric Matrix and Polymer@TiO₂ Nanocomposites

Applied Sciences
This study investigates the influence of positional isomerism on the physicochemical characteristics of polymeric matrices by examining polyo-anisidine (POA) and polyp-anisidine (PPA) in conjunction with TiO2 nanoparticles.

Mass spectral discrimination between monoenoic and cyclopropanoid, and between normal, iso, and anteiso fatty acid methyl esters

Journal of Lipid Research, 1969
Measurement of the ratio of the intensity of the parent molecular ion to that of the parent molecular ion minus 32 (the mass of methanol) can distinguish between monoenoic and cyclopropanoid fatty acid methyl esters with the same carbon number. A similar

Isosteric Substitution Enables Rational Design of Two‐Dimensional Energetic Crystals

Advanced Science, EarlyView.
Isosteric substitution transforms a classical nitro–amine motif into two‐dimensional aminofurazans with performance beyond TATB. ABSTRACT Two‐dimensional (2D) energetic crystals dissipate mechanical insult via interlayer slip, yet their molecular design space remains narrow.

Differential accumulation and elimination behavior of perfluoroalkyl Acid isomers in occupational workers in a manufactory in China.

Environmental Science and Technology, 2015
In this study, serum and urine samples were collected from 36 occupational workers in a fluorochemical manufacturing plant in China from 2008 to 2012 to evaluate the body burden and possible elimination of linear and branched perfluoroalkyl acids (PFAAs).

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.
