The potential of LiFePO4 as cathode material has not been fully exploited due to its intrinsic poor electronic and ionic conductivities. Attempts have been made to improve these properties of which coating of the active carbon on the particle surface is the most viable method so far. Phase-pure ...
Phase purity plays a vital role in achieving high capacity and long cycle life for lithium iron phosphate. Given that LiFePO4 has lower electronic and ionic conductivity, carbon coating on fine particle surface is often used in order to improve the electrochemical performance of LiFePO4. Unfortu...
High performance lithium iron phosphate (LFP) cathode materials were synthesized using amorphous carbon, carbon nanotubes (CNTs), and graphene (G) as conductive materials via sand milling and spray drying processes and followed by calcination. The structural characterizations indicated that CNTs...
A structural lithium ion battery is a material that can carry load and simultaneously be used to store electrical energy. We describe a path to manufacture structural positive electrodes via electrophoretic deposition (EPD) of LiFePO4 (LFP), carbon black and polyvinylidene fluoride (PVDF) onto c...
This study highlights the effects of a biomass-derived carbon coating on the properties of flexible lithium iron phosphate polymer batteries. Pure LiFePO4 (LFP) and carbon-coated LiFePO4 (C-LFP) cathode materials are synthesized by a modified mechanical activation process. LiFePO4 was uniformly ...
We reported the synthesis of the manganese(II) and manganese(III) complexes of a novel hexadentate Schiff base ligand (HBME) (1) obtained from the condensation of triethylenetetramine and 2 equiv. of 1-(biphenyl)-2-hydroxyimino-2-(morpholino)-1-ethanone. Hexadentate Schiff base ligand reacted wi...
The ligand Hpyramol (Hpyramol=4-methyl-2-N-(2-pyridylmethyl)aminophenol) is found to undergo an oxidative dehydrogenation of its amine function to an imine group upon coordination with iron(II) chloride and manganese(II) perchlorate. X-ray diffraction analyses for both complexes shows difference...
The Fenton process, one of several advanced oxidation processes, describes the reaction of Fe(II) with hydrogen peroxide. Fe(II) is oxidized to Fe(III) that reacts with hydrogen peroxide to Fe(II) and again initiates the Fenton reaction. In the course of the reactions reactive species, e.g. hydr...
Liquid phase oxidation of cyclohexane was carried out under mild reaction condition over copper pyrophosphate catalyst in CH3CN using hydrogen peroxide as an oxidant at the temperature between 25 and 80 °C. The copper pyrophosphate catalyst was characterized by means of XRD, FT-IR and water con...
During cementum formation, the key roles of osterix (Osx) and inorganic pyrophosphate (PPi), mainly controlled by nucleotide pyrophosphatase 1 (Npp1; encoded by the Enpp1 gene) and progressive ankylosis protein (Ank), have been demonstrated by animal models displaying altered cementum formation....
A chromatographic-densitometric method for identification and quantitation of diclofenac and its impurities, i.e. 1-(2,6-dichlorophenyl)indolin-2-one and indolin-2-one in pharmaceutical preparations and model solutions was developed. The effect of pH, temperature and ultra violet (UV) radiation ...
2,5-Di-tert-butyl-1,4-dimethoxybenzene is a redox shuttle for overcharge protection of LiFePO4-based lithium-ion batteries with a working potential lower than 4.2 V versus Li+/Li. However, an irreversible decomposition occurs when the working potential is higher than 4.2 V versus Li+/Li. 2,3,5,6...
Potassium enolates of alkyl aryl ketones react selectively in DMSO with phenylazo 1a and 4-methylphenylazo tert-butyl sulfide 1b undergoing respectively effective α-phenylation via SRN1 and α-(4-methylphenyl)hydrazonylation via elimination-addition.
The reaction of the tert-butyl-C60 anion (t-BuC60−) with tricyclopropylcyclopropenylium ion and 1,2-dicyclopropyl-3-(4-methylphenyl)cyclopropenylium ion underwent C–C covalent bond formation to give 1-tert-butyl-4-(2-cyclopropen-1-yl)-1,4-dihydro[60]fullerenes. The newly formed C–C bond of the...
The synthesis, characterization, DFT and, in two cases, the structure of seven novel dichloro(bis{2-[1-(4-methylphenyl)-1H-1,2,3-triazol-4-yl-κN3]pyridine-κN})metal(II) coordination compounds ([M(L2)2Cl2]), containing transition metals of groups 7–12, are described. Both experimentally measur...
This paper describes the total synthesis of the hydrochloride salts of (2S)-2-amino-7-methoxytetralin (21-HCl) and (2S)-2-amino-6-fluoro-7-methoxytetralin (ST1214), from a common enantiomerically pure aziridine 4b, which was available from l-aspartic acid β-tert-butyl ester. The synthesis of 21...
The synthesis, FT-IR, FT-Raman and NMR spectral analysis of an antimicrobial active benzoxazole derivative, 5-[(4-methylphenyl)acetamido]-2-(4-tert-butylphenyl) benzoxazole (MPATB) is reported. The localization of HOMO, LUMO plots in the title compound over the title molecule shows the charge tr...
A highly efficient and chemoselective hydrogenation of nitrobenzyl ethers to aminobenzyl ethers was developed by using a novel palladium–nickel bimetallic nanocatalyst. Since the catalytic selectivity was resulted from the synergistic effects between two metals rather than the traditional catal...
Currently there are several irreversible BTK inhibitors targeting Cys481 residue under preclinical or clinical development. However, most of these inhibitors also targeted other kinases such as BMX, JAK3, and EGFR that bear the highly similar active cysteine residues. Through a structure-based d...
Novel [n]benzofuranophanes (n = 8 & 10) 2a–b have been prepared by successive intramolecular cyclization from 5,19-di-tert-butyl-8,22-dimethoxy[n]metacyclophane-1-yne (syn-1a–b) by treatment with BBr3 in CH2Cl2 at room temperature for 8h. [2.n]Benzofuranophanes 2a–b were also obtained by trea...
