A new, simple, and fast one-pot synthesis of supported Au or Ag nanoparticles is implemented, for which a reactive Fe(II)-bearing green rust inorganic particle is used as an individual micro-reactor acting as both the reducing agent and support for the resulting metal nanoparticles. The mechanism involves both the solid-state oxidation of the green rust support (sulfate or carbonate) and the re...

Green retrofits, which improve the environment and energy efficiency of buildings, are considered a potential solution for reducing energy consumption as well as improving human health and productivity. They represent some of the riskiest, most complex, and most uncertain projects to manage. As the foundation of project management, critical success factors (CSFs) have been emphasized by previou...

Nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. In this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of Prangos ferulaceae leaves. The synthesized silver nanoparticles were characterized by UV-Vis spectroscopy, sc...

The roof garden has great functioning of smoothing the shortage of land resource in the city and making use of the land resource diversity and efficiently. The modern era, following the fast development of economic and society, people have a high claim to green roof or roof garden. It is an efficient and reasonable way to exploit the open space the roof of the building. From the classic roof ...

a highly efficient, simple and clean solvent-free protocol for the synthesis of polyhydroquinolines is described. the one-pot multi-component condensation reaction between arylaldehydes, dimedone (5,5-dimethylcyclohexane-1,3-dione), β-ketoesters and ammonium acetate in the presence of catalytic amount of (2.5 mol%) melamine trisulfonic acid (mtsa) as a recyclable, green and attractive sulfonic ...

A natural and efficient method has been developed for the synthesis of quinoline derivatives in good-to-high yields, from various aryl aldehydes, amines and phenyl acethylene, using marine sponge/I2 as a green catalyst

celecoxib is classified as none traditional nonsteroidal anti-inflammatory drugs (nsaids). this compound has conventional properties of nsaids such as anti-inflammatory, analgesic, and antipyretic activities beside reduced risk of gastrointestinal side effect of traditional nsaids such as ibuprofen. this compound gets a second sale rank of nsaids market at 2016 in the world and sales more than ...

In this review, we examine the greenest nanoparticles of zero-valent metals, metal oxides and metal salts, with emphasis on recent developments routes. Products from nature or those derived from natural products, such as extracts of several plants or parts of plants, tea, coffee, banana, simple amino acids, as well as wine, table sugar and glucose, have been used as reductants and as capping ag...

an aqueous extract of pimpinella anisum was used for green synthesis of silver nanoparticles by bio reduction of an aqueous solution of silver nitrate. silver nanoparticles were characterized by uv–vis spectrometry, fourier transform infrared spectroscopy (ftir), x-ray diffraction (xrd) analysis, scanning electron microscopy (sem) and energy-dispersive x-ray analysis (edax). the increase in abs...
