Cellulose tri-stearate (CTs) was synthesized employing trifluoroacetic anhydride (TFAA), stearic acid (SA), with microcrystal cellulose (MCC) and characterized with FT-IR and 1 H-NMR. The degree of substitution of CTs was determined by the traditional saponification method and 1 H-NMR. The thermal properties of CTs were investigated by the thermogravimetric analysis (TGA) under Ar flow in dynam...

abstract: two new transition metal complexes, containing the acidic ligand 5-chlorosalicylic acid (h2l5), and 1,10-phenanthroline（phen） and 1,3-di(4-pyridyl)propane (bpp) as secondary ligands are reported. they are formulated as {[pb(hl5)2(phen)(h2o)]·h2o}n(1), [zn2(hl5)4(bpp)2]n(2). all the complexes are characterized by single-crystal x-ray diffractions. compoud 1 crystallizes in the triclini...

Bhupal Dev, School of Physics and Astronomy, University of Manchester, Manchester, M13 9PL, UK e-mail: bhupal.dev@ hep.manchester.ac.uk We describe the evolution of Dark Matter (DM) abundance from the very onset of its creation from inflaton decay under the assumption of an instantaneous reheating. Based on the initial conditions such as the inflaton mass and its decay br...
