    Abstract Hexahydropyrimidine-based bis(phosphine), a pro-NHC ligand, was synthesized in one step and excellent yield. It underwent spontaneous double C-H bond activation to give cationic pincer NHC complexes of the type [(PCP)MCl]X (M = Pd, Ni and X = Cl, BF4) in the absence of any external reagents. Their structures were determined by X-ray diffraction methods and the mechanism of formation of palladium carbene complexes as analyzed by DFT calculations showed two transition states. The Pd(ii) carbene complex effectively catalyzes a few C-N cross coupling reactions.

    Abstract Perovskite oxides of the composition La1-xCaxMnO3 (LCM) have been investigated for the thermochemical splitting of H2O and CO2 to produce H2 and CO, respectively. The study was carried out in comparison with La1-xSrxMnO3, CeO2 and other oxides. The LCM system exhibits superior characteristics in high-temperature evolution of oxygen, and in reducing CO2 to CO and H2O to H2. The best results were obtained with La0.5Ca0.5MnO3 whose performance is noteworthy compared to that of other oxides including ceria. The orthorhombic structure of LCM seems to be a crucial factor.

    Abstract Back ground: One of the most prevailing diseases that required effective drug as therapeutic purposes is cardiac related illness includes myocardial infarction Current scenario makes enzyme to raises their sector towards therapeutic as effective active component for such diseases.
    Objectives: The main aim of the study was to isolate, screen, characterize and produce an extracellular thrombolytic protease from marine actinomycetes.
    Methods: Marine actinomycete was isolated and characterized on the basis of morphological, biochemical, and molecular characterization. The primary screening for protease activity was done by casein hydrolysis method followed by radial caseinolytic assay. The actinoprotease was partially purified using ammonium sulfate precipitation technique followed by dialysis and Sephadex G-50 gel permeation chromatography.
    Results: 16srDNA sequencing and BLAST search analysis of the sequence revealed close affiliation with Streptomyces genera and identified as Streptomyces violaceus VITYGM with 99% similarity. The specific activity of purified protease was found to be 1437 units/mg along with purification fold up to 1.5 times. The blood clot lysis activity was compared with the standard and found to lyse the blood clot with 97.43%. Till now very less evidences have been reported on actinoprotease. A single peak at retention time 0.9 min observed on high performance liquid chromatography (HPLC) confirmed the homogeneity of the preparation.
    Conclusion: This is the first study to report on actinoprotease from Streptomyces violaceus VITYGM. This study emphasizes the potency of novel actinoproteases as active compound in drugs for the treatment of cardiovascular diseases.

    Abstract Prompted by the early results on the catalytic activity of LiMn2O4 and related oxides in the photochemical oxidation of water, our detailed study of several manganese oxides has shown that trivalency of Mn is an important factor in determining the catalytic activity. Thus, Mn2O3, LaMnO3, and MgMn2O4 are found to be very good catalysts with turnover frequencies of 5 × 10(-4) s(-1), 4.8 × 10(-4) s(-1), and 0.8 × 10(-4) s(-1), respectively. Among the cobalt oxides, Li2Co2O4 and LaCoO3--especially the latter--exhibit excellent catalytic activity, with the turnover frequencies being 9 × 10(-4) s(-1) and 1.4 × 10(-3) s(-1), respectively. The common feature among the catalytic Mn and Co oxides is not only that Mn and Co are in the trivalent state, but Co(3+) in the Co oxides is in the intermediate t2g(5)e(g)(1) state whereas Mn(3+) is in the t2g(3e(g)(1) state. The presence of the e(g)(1) electron in these Mn and Co oxides is considered to play a crucial role in the photocatalytic properties of the oxides.

    Abstract As-synthesized single-walled carbon nanotubes (SWNTs) are mixtures of semiconducting and metallic species and separation of the two is of crucial importance for many applications. In this article, the methods employed for the enrichment of semiconducting and metallic SWNTs are presented, along with possible procedures to prepare either of the species selectively. Equally important are the methods for chirality selection. The discovery of metal-semiconductor transitions in SWNTs induced by interaction with electron donor and acceptor molecules is not only of academic interest, but may also find applications. Synthesis of Y-junction SWNTs with unique electronic properties at the junction is yet to be fully accomplished.

    Abstract Nanosheets of MoO3 that consist of only a few layers have been prepared by using four methods, including the oxidation of MoS2 nanosheets, intercalation with LiBr, and ultrasonication. These nanosheets have been characterized by atomic force microscopy and other techniques. Besides showing a blue-shift of the optical absorption band compared to the bulk sample, few-layer MoO3 exhibits enhanced photocatalytic activity. In combination with a borocarbonitride, few-layer MoO3 shows good performance characteristics as a supercapacitor electrode.
