Trimethylolpropane triacrylate (TMPTA) is a trifunctional acrylate monomer which polymerizes rapidly when exposed to sources of free radicals. It is widely used as a reactive diluent and polymer building block in the formulation of overprint varnishes, inks and a variety of wood, plastic and met...

Raman and resonance spectroscopy are shown to be capable of characterizing the tribromide and pentabromide anions and interstitial dibromine. The anions have Raman-active phonons which display a broad maximum in their excitation profiles at 600 nm, whereas interstitial bromine has a maximum in i...

Our recent studies on effective bromination and oxidation using benzyltrimethylammonium tribromide (BTMA Br3), stable solid, are described. Those involve electrophilic bromination of aromatic compounds such as phenols, aromatic amines, aromatic ethers, acetanilides, arenes, and thiophene, α-bro...

Stable crystalline organic ammonium tribromides (OATB), like Me4NBr3, Et4NBr3, Bu4NBr3, cetyltrimethylammonium tribromide, PyHBr3, can be readily synthesised from the reaction of the corresponding bromides with V2O5 and aqueous H2O2. Typically, TBATB, Bu4NBr3, brominates a variety of organic sub...

Reaction of 18-crown-6 with KBr and then with bromine (Br2) afforded a unique tribromide salt with a nanotube-like structure ({[K.18-crown-6]Br3}n). Oxidative coupling of thiols and bromination of some aromatic compounds is the first report on the chemistry of this reagent.

In designing highly efficient perovskite light-emitting diodes (PeLEDs), the most significant process is to deposit perovskite film without pinholes and vacancies because discontinuous film results in high leakage current. To fabricate a continuous methylammonium lead tribromide (MAPbBr3) film, ...

Publisher SummaryThis chapter discusses chemical and biochemical reactions The various forms of folic acid serve as coenzymes in several important biochemical reactions and concomitantly serve as a pool of 1-carbon units to be used in the synthesis of cellular constituents such as the amino acid...

We previously discovered that palmitic acid methyl ester (PAME) is a potent vasodilator first identified and released from the superior cervical ganglion and remain understudied. Thus, we investigated PAME's role in modulating cerebral blood flow (CBF) and neuroprotection after 6 min of car...

SummaryA method has been developed for measuring heat-produced reducing substances in milk products. The method employs a powerful oxidizing dye, porphyrexide, in conjunction with an indicator, p-aminodimethylaniline sulfate. In preliminary tests its usefulness is indicated by its measurement of...

High proton polarizations and long relaxation times have been observed in 50:50 mixtures of glycerol and water containing porphyrexide by using the solid effect. Results are reported for temperatures down to 0.28 K, and for magnetic fields between 19.6 and 29.4 kG. Comments are made on this mate...

The origin of oxygen atoms in oxido-bridged cubo-octahedral hexanuclear rhenium clusters [Re6(μ-O)12L6]+ (L – aromatic amine) has been investigated thoroughly. We confirmed that water is a crucial agent in the creation of the Re6(μ-O)12 core. The reaction of ReI3 with H218O and 3-methylpyridi...

The recovery and separation of rhenium and molybdenum from acidic aqueous solutions that simulate mine waters is studied through an adsorption process using magnetite nanoparticles functionalized with tertiary (TA-MNP) and quaternary amine (QA-MNP) groups as adsorbents. The functionalized nanopa...

The reaction of trans-[ReOCl3(PPh3)2] with 1-(benzothiazol-1-yl)-3,3-dimethylthiourea (Hbdt) in benzene led to the isolation of the oxorhenium(V) complex trans-[ReOCl(bdt)2] (1). However, repeating the reaction with [ReO(OEt)I2(PPh3)2] in acetonitrile led to the formation of the rhenium(III) com...

This review focuses on cytotoxic rhenium compounds in terms of IC50 values, their mode of action in biological systems and their status in clinical trials. Biological studies of different rhenium compounds ordered by the oxidation state of rhenium are presented. Numerous rhenium complexes are re...

Basic understanding on the spectroscopic behaviour of holmium ion (Ho3+) doped in magnesium zinc sulfophosphate glass host is essential for the development of inexpensive and eye–safe infrared solid state laser. To achieve this goal, six such glass samples were prepared using melt quenching met...

Clostridium difficile is an important enteric pathogen of humans and food animals. Recently it has been isolated from retail foods with prevalences up to 42%, prompting concern that contaminated foods may be one of the reasons for increased community-acquired C. difficile infection (CA-CDI). A n...

Sodium carbonate is a common electrolyte in high pH aqueous solution, and its contribution to the viscosity of those electrolytes solutions is of practical importance. Nitrate is isostructural with carbonate, and has nearly identical ionic radius. The relative importance of ionic size versus int...

A simple and efficient method for the regioselective nitration of various aromatic compounds by using sodium nitrate in the presence of melamine trisulfonic acid, is reported. This method provides several advantages such as good selectivity between ortho and para positions of aromatic compounds,...

The dynamic viscosities of six pseudobinary systems consisting of dl-2-aminobutyric acid + pseudo-unary solvent (aqueous sodium nitrate solutions) were determined, in the temperature range of 283.15–318.15 K, each 5 K under pressure of 101.1 kPa, using a microviscometer automatic Anton Paar (AM...
