Synthesis and applications of nano-structured iron oxides/hydroxides – a review
Mamata Mohapatra, S. Anand · 24 Feb 2011
The nano iron oxides have been synthesized by almost all the known wet chemical methods which include precipitation at ambient/elevated temperatures, surfactant mediation, emulsion/micro-emulsion, electro-deposition etc. Iron oxides in nano-scale have exhibited great potential for their applications as catalytic materials, wastewater treatment adsorbents, pigments, flocculants, coatings, gas sensors, ion exchangers, magnetic recording devices, magnetic data…
Use of zinc oxide nano particles for production of antimicrobial textiles
Ranguwar Rajendra, C Balakumar, HAM Ahammed et al. · 6 Sep 2010
The application of nanoscale materials and structures, usually ranging from 1 to 100 nanometers (nm), is an emerging area of nanoscience and nanotechnology. Synthesis of noble metal nanoparticles for applications such as catalysis, electronics, textiles, environmental protection, and biotechnology is an area of constant interest. Recently, an awareness of general sanitation, contact disease transmission, and…
Review on cadmium removal from aqueous solutions
K Rao, Mamata Mohapatra, S. Anand et al. · 21 Feb 2011
Cadmium is known to be toxic for living organism even if it is present in low levels. Generally it is associated with zinc and copper minerals and is produced as a byproduct of these industries. It enters the environment from electroplating, smelting, alloy manufacturing, pigments, plastic, cadmium-nickel batteries, fertilizers, pesticides, mining, pigments and dyes, textile…
Experimental studies on a vapour compression system using nanorefrigerants
N Subramani, M. Jose Prakash · 1 Jan 1970
Convective heat transfer is very important in the HVAC, refrigeration and microelectronics cooling applications. R134a is most widely adopted alternate refrigerant in refrigeration equipment, such s domestic refrigerators and air conditioners. Though the global warming up potential of R134a is relatively high, it is affirmed that it is a long term alternate refrigerants in lots…
