Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

Applications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

The use of alkyl cinnamates as UV screens for preventing the photo-yellowing of lignin-rich pulps

, 1994
A number of alkyl cinnamates and related compounds have been synthesized. Upon irradiation in solution, some of the materials undergo cis-trans isomerization and a cycloaddition reaction.

The Binding of Pentadiyl‐α,ω‐Bis(Dimethyldodecylammonium), a Cationic Gemini 12‐5‐12 Surfactant to Conjugated Carboxylates as Organic Counterions

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT The critical micelle concentration (CMC) values of the cationic gemini surfactant pentadiyl‐α,ω‐bis(dimethyldodecylammonium) bromide depend on the hydrophobicity of added conjugated organic carboxylate anions. Nine conjugated counterions, present as sodium salts of organic acids, were studied to expand the correlation to the counterion ...

Apple scar skin viroid causes dapple and scar skin apple diseases by disrupting phenylpropanoid‐mediated metabolic pathways

New Plant Protection, EarlyView.
Dapple apple and scar skin apple diseases are closely associated with suppression of anthocyanin biosynthesis and enhancement of suberin biosynthesis. Apple scar skin viroid (ASSVd) infection represses anthocyanin biosynthesis in apple callus. Abstract Apple scar skin viroid (ASSVd) causes dapple and scar skin apple diseases, posing serious threats to ...

Mechanistic insight into the formation of cinnamates in phosphine-free Heck reactions

, 2012
A mechanistic study of the formation of cinnamates in phosphine-free Heck reactions was performed. Pathways for migratory insertion, β-hydride elimination, and catalyst recovery were elucidated using density functional theory (DFT) methods.
