Effective molarities for diffusion-controlled r actions between spherical reactants with reactive patches are calculated analytically and by Brownian dynamics simulations. Unimolecular reaction systems with internal translational motion in one, two, and three dimensions are investigated and compared with bimolecular reactions in three dimensions. Rotational diffusion is included in all cases in...

We report the growth of gallium-based compounds, i.e., gallium oxynitride (GaON) and gallium oxide (Ga2O3) on multilayer graphene (MLG) on insulator using a mixture of ammonium nitrate (NH4NO3) and gallium nitrate (Ga(NO3)3) by electrochemical deposition (ECD) method at room temperature (RT) for the first time. The controlling parameters of current density and electrolyte molarity were found to...

Antibody  based  methods  have  numerous  advantages  compared  to  other  detection  methods. However, heavy metals cannot stimulate the immune antibody response; it is the main obstacle for preparation of the antibodies that used in detection methods of the metals. The production of the immunogenic Pb complexes by using cost benefit linkers of EDTA and DTPA were investigated in this  study.BS...

The thermal denaturation of the native DNA in solvents of varying salt concentrations was studied by viscometric and spectrophotometric methods. It was observed that within the molarity range of 0.02 M to 0.3 M, the melting temperatures obtained by the two independent methods agreed well, but that at lower ionic strength the agreement was not satisfactory. Both the visco­ metric and the spectro...

We report a synthesis of β-Ga2O3 nanostructures on Si substrate by electrochemical deposition using a mixture of Ga2O3, HCl, NH4OH, and H2O. The presence of Ga3+ ions contributed to the deposition of Ga2O3 nanostructures on the Si surface with the assistance of applied potentials. The morphologies of the grown structures strongly depended on the molarity of Ga2O3 and pH level of electrolyte. β-...

The research investigates the effects of super plasticizer and molarity of sodium hydroxide alkaline solution on the workability, microstructure and compressive strength of self compacting geopolymer concrete (SCGC). SCGC is an improved way of concreting execution that does not require compaction and is made by complete elimination of ordinary Portland cement content. The parameters studied wer...

In order to be applied into the body, intravenous fluids should be formulated to have an osmotic pressure similar to that of biological fluids. Physiologic acceptability of large-volume parenteral formulations in clinical practice is largely determined due to the osmotic effect of the dissolved solutes. Therefore, it is generally recommended that the labelling should list osmolarity. However, t...

Pepstatin has been shown to be an extremely potent inhibitor of human renin (Ki = 1.3 X lo-lo M). Kinetic analyses by several techniques show reversible interaction of pepstatin with renin and classical noncofipetitive inhibition. The high affinity of pepstatin for renin allows kinetic determination of the molarity of the enzyme in partially purified preparations. This method has been validated...
