an octahedral cobalt(iii) complex, trans-[(me2bpb)co(bzlan)2]clo4 (1), with h2me2bpb = n,n’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, ir, uv-vis, and 1h nmr spectroscopy. the structure of this complex has been determined by x-ray crystallography. the me2bpb2– is a di-anionic tetradentate ligand furnishing a ...

calcium dichloride tetra urea was prepared by the reaction of calcium chloride with urea in aqueous solution. the crystals are monoclinic, a= 7.633, b= 12.45 1, c= 8.118 ?,? = 113.17, z = 4, space group p 2,/a. the crystal structure was determined by single crystal x-ray methods and refined to r= 0.041. the calcium atoms are coordinated to four oxygen atoms of urea and to two chloride ions. the...

Nucleic acids are responsible for the storage of genetic information and directly participate in gene replication, transcription and expression, and thereby the control of nucleic acids leads to the regulation of genetic information flow and gene expression. Meanwhile, many non-coding RNAs are involved in signal transduction directly. Moreover, nucleic acid-based therapeutic strategies have bee...

This study investigates radiation damage in three metals the low temperature and high radiant flux regime using molecular dynamics a Frenkel pair accumulation method to simulate up $2.0$ displacements per atom. The considered include Fe, equiatomic CrCoNi, fictitious metal with identical bulk properties CrCoNi composed of single atom type referred as an A-atom. is found sustain higher concentra...
