The Faile growth method, when used with purified mercuric iodide (HgI2), along with low molecular weight polyethylene, has yielded tetragonal prismatic HgI2 crystals. Thermal desorption-gas chromatography/mass spectroscopy (TD-GC/MS) studies reveal the existence of alkanes and ketones in the gro...

The surface properties of mercuric iodide after etching in various cation iodide solutions have been investigated in terms of dissolution rate, morphology, electrical properties and reaction with water vapour. No significant differences have been observed in the etching rates. However, dissoluti...

Polycrystalline α-phase mercuric iodide (α-HgI2) film arrays have been prepared on ITO-coated glass substrates by hot-wall physical vapor deposition (HWPVD) method with the mask of 4 × 4 arrays. Film arrays are prepared based on one-step mask method. It is found that there exist differences b...

We present a review on mercuric iodide technology for room temperature gamma radiation detection. After four decades of research and development the material is attractive for a number of applications for x-ray and gamma-ray imagers with performances that match all competing materials. The cryst...

The mercury resources recovery and safe disposal of mercury-containing waste is an urgent problem. In this study, a new method using an iodide solution system was proposed to selectively recover mercury from high mercury-containing smelting wastes. The mercury leaching efficiency, yields, leachi...

Catalytic isomerization of n-hexane to its corresponding branched liquid hydrocarbon isomers by three different ionic liquids (ILs) having general formula; [BmimCl·2AlCl3], [BPyCl·2AlCl3] and [Et3NHCl·2AlCl3] were investigated in the present work. Due to the optimum acidic nature of the ILs, ...

The syntheses are described of 2,3-di-O-glycosyl derivatives of methyl α- and β-d-glucopyranoside having α-d-manno-, β-d-galacto-, α-l-rhamno-, α-l-fuco-, and β-l-fuco-pyranosyl substitutents at O-2 and O-3. The syntheses involved glycoslation of methyl 4,6-O-(benzylidene-α- (24) and β-...

The Schiff base, 4-[3-(4-methoxy-phenyl)-allylideneamino]-1,5-dimethyl-2-phenyl-1,2-dihydro-pyrazol-3-one (TPMC/AAP) was synthesized by the condensation of 4-aminoantipyrine (4-amino-1,5-dimethyl-2-phenylpyrazole-3-one) and trans-para-methoxycinnamaldehyde (trans-3,4-methoxyphenyl-2-propenal) in...

The non-natural enantiomer of polyoxamic acid (1) and 3,4-diepipolyoxamic acid (2) was synthesized in four steps from d-lyxono-1,4-lactone (4). Regioselective bromination of unprotected d-lyxono-1,4-lactone with HBr/AcOH led to 2-bromo-2-deoxy-d-xylono-1,4-lactone (5). This intermediate was trea...

Publisher SummaryThis chapter compiles a comprehensive list of the melting points and specific rotations of 2-amino-2-deoxy sugars slid their derivatives.

The effects of tris(pentafluorophenyl) borane (TPFPB) additive in electrolyte at the LiFePO4 cathode on the high temperature capacity fading were investigated by electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), cyclability, SEM and Fourier transform infrared (FTIR). Accordi...

Poly(carborane-siloxane) polymers were successfully synthesized by tris(pentafluorophenyl)borane catalyzing diorganohydroxysilanes (SiOH) and dihydrosilanes (SiH) to form siloxane bond and release hydrogen. The structure of monomers and polymers were characterized by 1H, 13C, 29Si NMR and FI-IR....

Oleandrin plant poisoning is common in children and the plant extract is used in Chinese medicines. The toxicity is due to oleandrin and the deglycosylated metabolite oleandrigenin. Bufalin and cinobufotalin (toad cardiac toxins) are also widely used in Chinese medicines like Chan SU, and Lu-She...

Cinobufotalin (CB), one of the bufadienolides prepared from toad venom, was investigated for its cytotoxicity, and the underneath mechanism involved. We primarily utilized DNA fragmentation assay and microscopic observation to assess the effect of various doses of CB in human lymphoma U937 cells...

Cinobufotalin (1), a major bioactive bufadienolide, has the potential anti-cancer activity. In the present paper, a scaled-up biotransformation of 1 by Aspergillus niger AS 3.739 and Alternaria alternate AS 3.4578 was performed for improving its biological activities and water-solubility. Seven ...

Lung cancer is a major cause of cancer-related mortality in the United States and around the world. Due to the pre-existing or acquired chemo-resistance, the current standard chemotherapy regimens only show moderate activity against lung cancer. In the current study, we explored the potential an...

This paper demonstrates that the crystallization of 3β-acetoxy-14α,15α-epoxy-5α-cholest-8-en-7-one from methanol affords the 3β-acetoxy-9α-methoxy-15α-hydroxycholest-8(14)-en-7-one. The structure of this steroid, which shows an apparently anomalous UV absorption maximum, is determined by ...

Novel composite films of low-density polyethylene (LDPE) containing photosensitizing riboflavin (RB) were developed to enhance the broad-spectrum light barrier for the application of light-sensitive food packaging with an additional antimicrobial property. With the conjugated aromatic ring syste...

Commercial riboflavin production with Bacillus subtilis has been developed by combining rational and classical strain development for almost two decades, but how an improved riboflavin producer can be created rationally is still not completely understood. In this study, we demonstrate the combin...

In this study, we evaluated the effect of oral administration of riboflavin combined with whole-body ultraviolet A (UVA) irradiation on the biochemical and biomechanical properties of sclera in a guinea pig model to control the progression of myopia. Experimental groups were administered 0.1% ri...
