Golnaz Parhizgar Mona Hosseini-Sarvari,

Epoxides undergo regioselective ring opening with various nucleophiles using catalytic amount of nano magnesium oxide and water as solvent under mild reaction conditions. The remarkable features of this method are improved yields, high regioselectivity, and green chemistry agreement.

Introduction: Today, the use of green information technology has positive effects on the health system, especially in controlling energy waste, reducing paperwork, lowering the use of technology and medical devices, and enhancing environmental and economic performance. This study aimed to investigate the challenges of implementing green information technology in hospitals and treatment centers....

: Concept maps of chemistry can be obtained from thesaurus of chemistry. Analysis of information in the field of chemistry is done at graduate level, based on comparing and analyzing chemistry dissertations by using these maps. Therefore, the use of thesaurus for analyzing scientific information is recommended. Major advantage of using this method, is that it is possible to obtain a detailed ma...

Many of the basic concepts of green chemistry are familiar to pollution prevention practitioners. The concepts of substituting less hazardous materials into chemical formulations and reducing wastes have been around for many years. Green chemistry has taken these concepts and expanded the scope of possibilities by fully evaluating all aspects of chemical reactions, processes and formulations. T...

Amidoalkyl-2-naphthols as synthetic intermediates play an important role in medicinal chemistry due to their remarkable biological and many pharmacological properties. Owing to the versatile biological activities, industrial and synthetic applications of these compounds, introduction of an alternative methodology is urgent in synthetic organic chemistry. Low yield and harsh reaction conditions ...
