Photoelectronic properties of nanocrystalline CdSethin films prepared by chemical bath deposition (CBD) technique at room temperature are studied taking its molar concentration as a function. Structural analysis the deposited thin shows that change molarity brings variation in crystalline sizes films. Such show suitable photoelectronic for construction different optoelectronic devices. The phot...

A pn-junction was successfully fabricated by depositing n-type CdSe thin films on p-type Si as a substrate using chemical bath deposition technique (CBD) at 70oC. Time of 6 hours and the preparing solution changed every 2 during deposition. Sodium Selenosulfate (with different weights) is source Se-2 ions, cadmium nitrate Cd+2 ions. The (I-V) characteristics for n-CdSe/p-Si junction show it beh...

Despite extensive in-depth research into high calcium fly ash geopolymer concretes and a number of proposed methods to calculate the mix proportions, no universally applicable method determine proportions has been developed. This paper uses an artificial neural network (ANN) machine learning toolbox in MATLAB programming environment together with Bayesian regularization algorithm, Levenberg-Mar...

We derive a thermodynamically consistent model for liquid-solid phase change in sea ice by incorporating sensitive scalar to classical framework of change. The entropy the is taken relative liquid molar fraction which induces chemotactic behavior. This provides transparent mechanism rejection under formation solid phase. identify slow varying coordinates, including density molarity weighted lat...

Several esters of 4-methylumbelliferone and 2-naphthol were synthesized and examined as possible spectrofluorimetric titrants for bovine alpha-chymotrypsin, trypsin, thrombin, Factor Xa and for subtilisin Novo. 4-Methylumbelliferyl p-guanidinobenzoate hydrochloride (MUGB) is a satisfactory titrant for alpha- and beta-trypsin, thrombin and Factor Xa and 4-methylumbelliferyl p-(NNN-trimethylammon...

Synergistic interactions between specific magnetic field intensities and chemical concentrations are challenging biophysical phenomena. Planarian were exposed to one of five different concentrations of melatonin and to a “geomagnetic”—patterned 7 Hz amplitude modulated magnetic field for 6 min once per hour for 8 hr during six successive nights. The peak average strengths were within the range ...

In this paper, we have reported a low-concentration active electrolyte of KBrO3 for the supercapacitor’s application. The electrochemical processes were carried out in two concentrations with 0.2 and 0.4 M. Additionally, novel strategy doping graphene during its fabrication process potassium bromide (KBr) solution. chemical KBr improved properties used as supercapacitors. HRTEM images confirmed...

The accumulation of polyhydroxyalkanoates (PHAs) by microorganisms usually occurs in response to environmental stress conditions. Therefore, it is advantageous choose two-step cultivation. first phase aimed at maximizing biomass production, and only the second phase, after setting suitable conditions, PHA production starts. aim this work was optimize composition minimal propagation medium used ...
