Computational studies considering both thermodynamic and kinetic aspects revealed that graphyne, a carbon material that has recently been of increasing interest, favours unprecedented homogeneous "in-plane" addition reactions. The addition of dichlorocarbene to the C(sp)-C(sp) bond, a site with outstanding regioselectivity in graphyne, proceeds via a stepwise mechanism. Due to their homogeneous...

Defects change essentially not only the electronic properties but also the chemical properties of graphene, being centers of its chemical activity. Their functionalization is a way to modify the electronic and crystal structure of graphene, which may be important for graphene-based nanoelectronics. Using hydrogen as an example, we have simulated a chemistry of imperfect graphene for a broad cla...

Structured Product Labels (SPLs) contain information about drugs that can be valuable to clinical and translational research, especially if it can be linked to other sources that provide data about drug targets, chemical properties, interactions, and biological pathways. Unfortunately, SPLs currently provide coarsely-structured drug information and lack the detailed annotation that is required ...

in this study, chemical composition and functional properties of red bean, chickpea, lentil and canellini bean were evaluated. our results revealed that chickpea had the highest protein (43.4%) and fat (5.17%) content and lentil, red bean and canellini bean were the following ones. the isoelectric point of all the samples were determined as about ph=4 but other than lentil, the remaining sample...

introduction: reuse of wastewater for agricultural irrigation is increasing due to an increased demand for water resources in different parts of the world. almost 70% of deviated water from rivers and pumped groundwater is used for agriculture. if wastewater is used for irrigation in agriculture, then the amount of discharged water from natural sources will be decreased and the flow of wastewat...

owing to the importance and necessity of identifying soil properties in arid rangeland management, and the variableeffects of different kinds of herbivores on soil, this study compares some of the physical and chemical properties ofsoil between two regions experiencing livestock and wildlife grazing in the desert rangelands of kalmand-bahadoranin yazd province. the key areas in two regions expe...

the oil extracted from three major canola cultivars (hyolla401, hyolla420 and rgs003) grown in golestan province was analyzed for physico-chemical properties, fatty acid composition, minerals content, and stability during 16 weeks of storage. according to the results, the highest iodine value and refractive index belonged to hyolla401. the highest saponification value was observed in hyolla420....
