Single-crystal X-ray diffraction study of novel pyrazole chalcone derived from 1-phenyl-3-p-tolyl-1H-pyrazole-4-carbaldehyde

143-146Novel pyrazole chalcone has been synthesized by reaction of phenyl-3-p-tolyl-1H-pyrazole-4-carbaldehyde and acetophenone by Claisen-Schmidt reaction in ethanol by microwave assisted method. It has been characterized by elemental analysis and spectroscopic (FTIR, 1H NMR and MS) studies. Crystal structure of the compound has been determined using single-crystal X-ray diffraction. Hydrogen-bonded chain is formed by C–H···O bonding enhanced by C–H···π interaction. Adjacent chains are connected through the π∙∙∙π interactions

Crystallographic study shows formation of hydrogen-bonded cyclic tetramer around a 2-fold axis and 4-fold roto-inversion axis through N1–H1···O1 interactions between the indolic NH group as a hydrogen-bond donor and the carbonyl O atom as a hydrogen-bond acceptor

Study of combustion of coal with magnegas as additive for improved combustion efficiency: A review of present scenario and future scope1) A combustion/deposition entrained reactor for high-temperature/pressure studies of coal and coal minerals The future

Articles you may be interested in Abstract. Fossil fuels are contributing the largest share in meeting up energy demands of urban lifestyle across the globe. May it be gasoline or coal, all sort of fossil fuels are drilled out of earth crust to burn on the earth surface creating huge burden on air quality. Incomplete combustion of fossil fuels cause pollution of carbon monoxide and other gases. It also eats away the breathable oxygen from atmosphere. Rampant use of coal in power sector causes above problems adding to the global warming phenomenon. Magnecules and magnehydrogen are seen to be best additives to fossil fuels which can effectively enhance the combustion efficiency of fossil fuels. Present paper discusses the enhancement in combustion efficiency of fossil fuels in terms of increased utility of carbon and improved quality of emission reducing the amount of obnoxious gases

Microwave Assisted Synthesis and Antimicrobial Study of Schiff Base Vanadium(IV) Complexes of Phenyl Esters of Amino Acids

Schiff base vanadium(IV) complexes of phenyl esters of the two acidic amino acids, i.e., aspartic and glutamic acid, were synthesized. The phenyl esters of these amino acids were synthesized by conventional method whereas the Schiff base vanadium(IV) complexes were synthesized using microwave irradiation. The complexes were characterized by spectroscopic tools such as IR, 1H NMR, mass (ES), ESR, and UV visible spectroscopy. All the complexes were studied for antibacterial and antifungal activity and found to be moderately active
