Rate measurements, density functional theory (DFT) within the framework of transition state theory, and ensemble-averaging methods are used to probe oxygen selectivities, defined as the reaction probability ratios for O reactions with CO and CH4, during CH4–O2 catalysis on Pt and Rh clusters. CO2 and H2O are the predominant products, but small amounts of CO form as chemisorbed oxygen atoms (O )...

Disulfonated rhodamines are photostable and bright dyes widely used in life science optical microscopy. However, di-sulfonated were considered cell impermeable not applicable living cells. We challenged this assumption with 5 most popular (Rho) having two carboxylic acid residues, versatile sulfonation patterns emitting green (AS488), yellow (Rho530), orange (Rho565) red (Rho590 STAR RED) light...

one way to increase the shelf life of agriculture products is using of controlled atmosphere storages. in order to obtain the controlled gas components, an equipped cold store with cooling system and atmosphere controller system designed and constructed. the injection of co2, o2 and n2 were controlled automatically into the store by programable logic control (plc). the store was a laboratory re...

agricultural activities have always been partly responsible for the emission of greenhouse gases and other environmental contaminants in the atmosphere. thus, studying on the environmental effects of agricultural activities and proposing appropriate strategies to mitigate these adverse effects can be paramount importance. in this study, in order to determine the environmental impacts of peanut ...

this study aimed to evaluate the environmental consequences of kiwifruit production in guilan province of iran by the life cycle assessment (lca) methodology during growing season of 2011-2012. data were obtained from 84 kiwifruit producers using a face to face questionnaire method. for this purpose, a functional unit equal to one ton kiwifruit was assumed based on iso 14040 method. impacts of ...
