the interaction between nano-sio2 and lysozyme was investigated by the method of uv-visible  detection and fluorescence spectroscopic techniques. the thermal denaturation of lysozyme has been investigated in the presence and absence of nano-sio2 over the temperature range (293-373) k in different buffers and ph values, using temperature scanning spectroscopy. the presence of nano-sio2 caused th...

Bee bread is a food product obtained by fermenting bee pollen with honey and storing it in honeycomb cells. In this fermentation, phenolic compounds remain unaffected unchanged. contains approximately; there are 35% sugar, 24-35% carbohydrate, 20-22% protein, 3.5% lactic acid, 2.43% mineral, 1.6% lipid fat. Within the scope of study, biocompatible iron nanoparticles were synthesized (BB@FeNPs) ...

To address the perpetual need for STEM education resources that foster an interest in scientific research, promote a positive public perception of science, and create appreciation relevance data decision-making, we developed modular set undergraduate laboratory exercises influenced by ongoing basic research towards elucidating chemical composition pure maple syrups. Maple syrup has garnered att...

As known, in the synthesis of conductive polyaniline polymer from aniline monomer, polymerization medium must be acidic. In order to make acidic, protonic acids such as HCl and H2SO4 are generally used. this study, two have been used One them, we know, is a acid. The other acid zinc ion, which Lewis metal ion has never for purpose up now. Two polymers synthesized prove that can also presence io...

In this work, nanostructured TiO2 and Cr-doped TiO2 thin films were deposited on glass substrate through sonochemical-chemical vapor deposition (CVD) method. The resulting thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible absorption spectroscopy, and photoluminescence spectroscopy techniques. The TiO2 thin film has nanocubic morphology and ...

Natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. In the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

Proteins interact with their ligands to form active and dynamic assemblies which carry out various cellular functions. Elucidating these interactions is therefore fundamental for the understanding of cellular processes. However, many protein complexes are dynamic assemblies and are not accessible by conventional structural techniques. Mass spectrometry contributes to the structural investigatio...
