The F(1) part of the F(1)F(O) ATP synthase from Escherichia coli has been crystallized and its structure determined to 4.4-A resolution by using molecular replacement based on the structure of the beef-heart mitochondrial enzyme. The bacterial F(1) consists of five subunits with stoichiometry alpha(3), beta(3), gamma, delta, and epsilon. delta was removed before crystallization. In agreement wi...

This study observed the effect of addition iron (Fe) doping on characteristics Zinc Oxide (ZnO) nanoparticles.Zn(1-x)Fe(x) with various concentration x = 0, 2, 4, 6, 8, and 10% was prepared by coprecipitation method using Sodium Hydroxide Hydrogen Chloride. The adding Fe ZnO characterized X-ray Diffraction (XRD) to determine crystal structure, size, strain. analysis result confirmed absence add...

Crystalline antimony sulfide (Sb2S3) with nanorods morphology was successfully prepared via hydrothermal method by the reaction of elemental sulfur, antimony and iodine as starting materials with high yield at 180°C for 24h.Using oxidation reagents like iodine as an initiator of redox reaction to prepare Sb2S3 is reported for first time. Crystal growth of Sb2S3 was done by increasing reaction t...

Polar organic nonlinear optical material, L-tartaric acid single crystals have been grown from slow evaporation solution growth technique. Single crystal X-ray diffraction study indicates that the grown crystal crystallized in monoclinic system with space group P21. Crystalline perfection of the crystal has been evaluated by high resolution X-ray diffraction technique and it reveals that the cr...

Two new organic–inorganic salts of perhalidometallates with protonated organic amine cations have been synthesized and characterized by X-ray diffraction thermal analysis. (CHBMAH2)ZnBr4·3/2H2O 1 (CHBMAH2)ZnCl4 4 [(CHBMAH2)2+: 1,3-cyclohexanebis(methylammonium)] were obtained in single-crystal form. The crystal packing all the compounds is governed formation various non-covalent intermolecular ...

the zinc(ii) complex [zn2(dmdtc)2(μ-dmdtc)2] has been synthesized directly from thiram ligand, containing a disulfide bond {dmdtc = n,n-dimethyldithiocarbamate; thiram = n,n-tetramethylthiuram disulfide}, and characterized by elemental analysis and spectroscopic methods. surprisingly thiram, undergoes a reductive disulfide bond scission upon reaction with zn2+ in methanolic media to give the [z...

Optical quality single crystals of glycine thiourea (GT), a new organic nonlinear optical (NLO) crystal, were grown from aqueous solution by slow evaporation method. Solubility of GT was determined at various temperatures. Single crystal X-ray diffraction studies indicate that GT crystallizes in the monoclinic crystal system. Various diffracting planes of the grown crystal were identified from ...
