Abstract Blood coagulation is a process, which initiated by certain physico-chemical effects. This process results in change the blood from sol state, that well suited for further processing, to gel state. 13 clotting factors take part cascade system of coagulation. Trisodium-citrate affects factor IV, calcium, and prevents texture. The effect different concentrations trisodium-citrate (0, 0.48...

Capsular polysaccharides (SPS) are the integral components of gram-negative bacteria, and also have potential uses as vaccines. In this paper, interaction of anionic SPS, isolated from Klebsiella K28, K43, K51 and K20, with cationic surfactants and cationicnonionic mixed surfactants were investigated by turbidimetric titration, viscometric method. Variation of size and zeta-potential was measur...

The apparent wall slip (AWS) effect, accompanying the flow of colloidal dispersions in confined geometries, can be an important factor for the applications of nanofluids in heat transfer and microfluidics. In this study, a series of dilute TiO2 aqueous dispersions were prepared and tested for the possible presence of the AWS effect by means of a novel viscometric technique. The nanofluids, prep...

A series of three isomeric 4-[(n-bromophenyl)carbamoyl]butanoic acids (n = 2, 3 and 4) were synthesized their structures confirmed by FTIR, NMR, MS, micro elemental analysis (CHN) single crystal X-ray crystallography. Kinks are noted in the molecular n 2 compounds, namely about methylene-C–C(carbonyl) N–C(phenyl) bonds; no such twist former bond is seen 4 molecule. In packing, supramolecular ta...

We present a viscometric affinity biosensor for continuous monitoring of glucose in biological fluids such as blood and plasma. The sensing principle of this chemico-mechanical sensor is based upon the viscosity variation of a sensitive fluid with glucose concentration. Basically, this device includes both an actuating and a sensing piezoelectric diaphragms as well as a flow-resistive microchan...

Bioactive 1,1'-(4,4'-di-ferrocenyl)di-phenyl thiourea and various metal complexes of this ligand have been successfully synthesized and characterized by using physicoanalytical techniques such as FT-IR and multinuclear ((1)H and (13)C) NMR spectroscopy along with melting point and elemental analyses. The interaction of the synthesized compounds with DNA has been investigated by using cyclic vol...
