Microwave Assisted Synthesis of N-Substituted-7-hydroxy-4-methyl-2-oxoquinolines as Anticonvulsant Agents

E-Journal of Chemistry, 2011
The reaction of resorcinol with ethylacetoacetate yielded the 7-hydroxy-4-methyl coumarin (1), which on treatment with benzidine gives 1-(4ʹ-amino-biphenyl-4-yl)-7-hydroxy-4-methyl-1H-quinolin-2-one (2). 1-{4ʹ-[(Substituted benzylidene)-amino]-biphenyl-4-

Identification of biphenyls - contaminants responsible for off-flavour in soft drinks

Czech Journal of Food Sciences, 2018
Off-flavour in soft drinks is one of the main threats to manufacturers, which can result in expensive recalls, and discredit the brand. Off-flavours can occur for a variety of reasons (e.g . chemical contamination of raw material).

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

Peripherally Fluorinated Tetraphenylethene: New Electron Extraction Interlayers for n‐i‐p Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Fluorinated tetraphenylethene (TPE) derivatives were developed as interfacial layers for perovskite solar cells. The optimized TFP‐TPE enhances interfacial compatibility, suppresses molecular aggregation, and improves charge extraction. Devices incorporating TFP‐TPE achieved a record efficiency of 25.29% and outstanding stability under humidity and ...

Qualitative change in structural dynamics of some glass-forming systems

, 2015
Analysis of temperature dependence of structural relaxation time in supercooled liquids revealed a qualitatively distinct feature - a sharp, cusp-like maxumum in the second derivative of its logarithm. It suggests that the super-Arrhenius behavior of the
