In the past two decades, use of biomolecules, either from biological or biomimetic systems (or so-called synthesis), has emerged as a promising green approach to synthesize gold nanomaterials (Au NMs). Here, we describe recent progress on and syntheses Au NMs. We focus our discussions selection principles synthesis mechanisms involving evolution synthesis, contributions bioinspired production h...

a facile and green approach has been developed to synthesize silver nanoparticle (ag-nps). this was carried out by a biosynthetic route using justicia adhatoda root extract as reducing and stabilizing agent. the structure, composition, average particle size (~25 nm) and surface morphology of ag-nps were characterized by the x-ray diffraction, transmission electron microscope and atomic force mi...

a simple chemical vapor deposition technique at atmospheric pressure (apcvd) is adopted to synthesize the aligned arrays of functionalized multi-walled carbon nanotubes (amwcnts) without using any carrier gas, at 230◦c, 750◦c and 850 ◦c. camphor (c10h16o) is used as carbon source because this botanical hydrocarbon is chip and abundant which convert the cvd technique to a green method for produc...

Removing one key barrier to the industrial uptake of green chemistry and nanocatalysis in fine specialty chemical industry requires fill an ongoing “talent shortage” via expanded education. In this study we show how use hybrid sol-gel catalysts synthesize chemicals active pharmaceutical ingredients flow reactors illustrates new ideas reshape education based on recent research outcomes, visualiz...

The austenitic stainless steel (SS) has been used as a material for  building  ultra  high  vacuum  (UHV)  chamber.  Recently significant  efforts  have  been  concerned  a  comparing  the standard  cleaned  for  ultra  high  vacuum,  passivity  stainless. In  this work Austenitic  nanocomposites were  synthesize by sol-  gel method. The morphologies  and  topographies  of  the samples  h...

Abstract The study is part of humanity's current concerns tempering climate change for sustainable development, in the context where construction sector responsible a significant percentage greenhouse gas emissions. In present work, through rigorous documentation, authors synthesize several existing green and building certification systems. Extending from buildings to neighbourhoods, university...

background & aim: in this study, is done during one-year research on blue–green and green algae for antimicrobial activity in mashhad suburb. aqueous, ether, and methanol extracts from 44 species blue – green algae and green algae were examined for antimicrobial properties against four bacteria (tow positive gram bacteria and tow negative gram bacteria) and tow fungous. material & meth...
