The ability of a series of choline analogs to produce a form of dwarfism in wheat was recently described by Tolbert (7). One of the more potent compounds tested was allyl trimethylammonium bromide (AMAB). The most characteristic effect upon the growth of Thatcher wheat after treatment of the roots with AMAB was the development of stockier plants with short thick stems. This pronounced dwarfism ...

A tetracationic viologen based on dimethylaminoethanol is reported as a novel negolyte for aqueous-organic flow batteries. The compound (1,1′-bis(3-((2-hydroxyethyl)dimethylammonio)propyl)-[4,4′-bipyridine]-1,1′-diium tetrachloride), termed [(DMAE-Pr)2-Vi]Cl4, was prepared by replacing the trimethylammonium groups of former analogue derivatives permanently charged moieties, improving its solubi...

Abstract Copolymers of [2-(acryloyloxy)ethyl]trimethylammonium chloride (AETAC) and acrylamide (AAm) (AETAC- co -AAm) are polyelectrolytes used as flocculants in wastewater purification. Diffusion-ordered two-dimensional NMR spectroscopy (DOSY) experiments for AETAC- -AAm samples with M w ranging from 1.9 to 3.9 million a polyacrylamide sample 1.3 were carried out pure D 2 O containing 0.1 or 1...

background: dna vaccines are third generation vaccines which have made promises to combat infectious diseases. cationic liposomes are used as effective delivery systems for dna vaccines to generate stronger immunity. objective: encapsulation of pcdna3.1+pa plasmid, encoding protective antigen (pa) of bacillus anthracis (b. anthracis) into cationic liposomes, and evaluation of its effect on spec...
