Physical chemistry is the branch of chemistry that establishes and develops the principles of the subject in terms of the underlying concepts of physics and the language of mathematics. Its concepts are used to explain and interpret observations on the physical and chemical properties of matter. Physical chemistry is essential for developing and interpreting the techniques used to determine str...

physicochemical and mechanical properties of wheat grains can have a great impact on the quality of the final products (bread). therefore, correct selection of wheat cultivar for specific applications seems to be crucial. in this study, the differences in the physicochemical and mechanical properties (under compression and impact loadings) of ten iranian wheat cultivars (azar2, alamut, bam, bah...

BACKGROUND Using treated wastewater in agriculture irrigation could be a realistic solution for the shortage of fresh water in Iran, however, it is associated with environmental and health threats; therefore, effluent quality assessment is quite necessary before use. The present study aimed to evaluate the physicochemical and microbial quality of Shiraz wastewater treatment plant effluent for b...

Nineteen physicochemical properties of natural amino acids are correlated by combination of a large number of molecular descriptors considering simple connectivity of atoms, their topological orientations in two dimensions and quantum-chemical molecular descriptors describing interactions among them. All the molecular descriptors are amalgamated to generate the principal components, which are d...

The aim of present study was to carry out pharmacognostic and physicochemical evaluation of fruits of Gmelina arborea. Fresh fruits and dried powder of the fruits were studied by morphology, microscopy, qualitative chemical test and florescence analysis of powdered drug. Other physicochemical parameters were also performed as per WHO guide lines. The detailed microscopy revealed the presence of...

The origin of the concept of a molecular complex between oxygen and hemoglobin can be traced to Stokes, a century and a half ago. Subsequently, physicochemical concepts of equilibria provided a path to quantitative formulations of these ligand-receptor interactions. Then, it took a quarter of a century before a proper format was prepared in terms of four stoichiometric equilibria and their asso...

Public health is at risk from physical and chemical contaminants in the drinking water which may have immediate health consequences. The data from the current study was evaluated for groundwater quality in the rural villages of Neyshabur County in Iran. For determination of the essential physicochemical parameters, water samples were collected from 30 randomly-selected water wells during 2013 a...

Persea macrantha (Nees) Kosterm (Lauraceae) is an important traditional medicinal plant being used for treatment of asthma and rheumatism. Systematic pharmacognostical evaluation of bark of the plant has been carried out with respect to macroscopy, microscopy, physicochemical parameters and estimation of different standards. TLC profiles were developed for petroleum ether and chloroform extract...
