Industrial ammonia production mainly relies on the conventional Haber–Bosch process accompanied by high energy consumption and plentiful carbon dioxide emissions, which triggered recent interest to explore more energy‐efficient environmentally benign alternatives. Very recently, electrochemical nitrite reduction in an aqueous medium promises new opportunities for advanced, energy‐efficient, sus...
This article suggests that sexual and reproductive health and rights activists seeking to influence the post-2015 international development paradigm must work with sustainable development advocates concerned with a range of issues, including climate change, environmental issues, and food and water security, and that a way of building bridges with these communities is to demonstrate how sexual a...
Universities can contribute to the solutions of major challenges of the 21st century such as increasing environmental and socio-economic crises, inequalities of income and wealth and political instabilities by integrating the concept of sustainable development (SD) in research, organization, and by educating future decision makers. For instance, by integrating sustainability into the organizati...
This procedure has developed the use of TiO2 nanoparticles as an environmentally friendly and highly efficient heterogenous nanocatalyst for the eco-safe, facile and one-pot three-component Biginelli synthesis of biologically active corresponding 3,4-dihydropyrimidin-2-(1H)-one/thione derivatives under solvent-free conditions. This eco-friendly protocol provi...
Catalytic Hydrothermal Liquefaction of Artichoke Residues (Cynara Scolymus L.) to Valuable Chemicals
Lignocellulosic biomass is accepted to be one of the best sustainable alternatives for overcoming fossil fuel dependence and reduce environmental pollution. Intensive research studies have been carried out on conversion this big potential source via chemical biochemical processes miscellaneous chemicals. According present methods conversion, cellulose hemicellulose parts plant can converted pla...
Multi-component coupling reaction (MCR) is a powerful synthetic tool for the synthesis of biologically active compounds. Development of such multi-component coupling reaction strategies in visible light has been of considerable interest, as they provide simple and rapid access to a large number of organic molecules through a sustainable path. An efficient and green protocol for the synthesis of...
doing centralized and coherent activities between governmental agencies is essential at any level. creating suitable institutional structure for appropriate solutions of policy problem in natural resources at multiple levels is possible using application of network governance. the aim of this paper is institutional network analysis with co-management of zagros dry forests in regional (county) l...
