Synthesis, spectral correlation and insect antifeedant activities of some 2-benzimidazole chalcones

open access: yesJournal of Saudi Chemical Society, 2016
Some substituted styryl 2-benzimidazole ketones have been synthesised by fly-ash:H2SO4 catalysed aldol condensation of 2-benzimidazole methyl ketone and various substituted benzaldehydes in microwave oven. The yields of these chalcones are more than 70%.

Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.

Solvent-free synthesis of azomethines, spectral correlations and antimicrobial activities of some E-benzylidene-4-chlorobenzenamines

open access: yesBulletin of the Chemical Society of Ethiopia, 2015
Some azomethines including substituted benzylidene-4-chlorobenzenamines (E-imines) have been synthesized by fly-ash: PTS catalyzed microwave assisted condensation of 4-chloroaniline and substituted benzaldehydes under solvent-free conditions.

The hydrolysis of phosphocreatine and the origin of urinary creatinine [PDF]

open access: yes, 1947
Shaffer (1), Myers and Fine (2), and Hahn and Meyer (3) adduced evidence that muscle creatine is the precursor of urinary creatinine. This was questioned by Chanutin and Kinard (4) but was conclusively proved by Bloch, Schoenheimer, and Rittenberg (5, 6)

Asymptotic-Preserving scheme for a bi-fluid Euler-Lorentz model [PDF]

open access: yes, 2011
The present work is devoted to the simulation of a strongly magnetized plasma considered as a mixture of an ion fluid and an electron fluid. For the sake of simplicity, we assume that the model is isothermal and described by Euler equations coupled with ...

For a Caring Geography: Situated Solidarities and Feminist Care Ethics During and Beyond Crisis

open access: yesArea, EarlyView.
ABSTRACT This paper calls for a caring geography that centres care and solidarity as interrelated, embodied practices rather than abstract concepts. Drawing on feminist ethics of care and scholarship on geographies of solidarity, I argue that care becomes politically transformative when coupled with solidarity, understood as negotiated mutuality across

The Substituent Effect on the Radical Scavenging Activity of Apigenin

open access: yesMolecules, 2018
Flavonoids widely found in natural foods are excellent free radical scavengers. The relationship between the substituent and antioxidative activity of flavonoids has not yet been completely elucidated. In this work, the antioxidative activity of apigenin
