Green synthesis of fibrous hierarchical meso-macroporous N doped TiO2 nanophotocatalyst with enhanced photocatalytic H-2 production

Parida, K.M.; Pany, S.; Naik, B. (International Journal Of Hydrogen Energy, 38(9), 2013: 3545-3553)

A new approach to prepare hierarchical and fibrous meso-macroporous N-doped TiO2 is attempted at room temperature without using templates by the addition of titanium isopropoxide droplets to the ammonia solution. The ...
Enhanced hydrogen production over CdSe QD/ZTP composite under visible light irradiation without using co-catalyst

Biswal, N.; Parida, K.M. (International Journal Of Hydrogen Energy, 38(3), 2013: 1267-1277)

A series of CdSe quantum dot (QD)/zirconium titanium phosphate (ZTP) was synthesized by solvothermal method using ethylene diamine by varying Cd to Se ratio from 1:1 to 1:4 and examined as robust catalysts for hydrogen ...
A computationally efficient frequency-domain filtered-X LMS algorithm for virtual microphone

Das, D.P.; Moreau, D.J.; Cazzolato, B.S. (Mechanical Systems And Signal Processing, 37(1-2), 2013: 440-454)

The computational complexity of the virtual FXLMS algorithm is higher than that of the conventional FXLMS algorithm. The additional complexity comes from computation of three secondary path transfer functions (as opposed ...
Investigations on different starches as depressants for iron ore flotation

Kar, B.; Sahoo, H.; Rath, S.S.; Das, B. (Minerals Engineering, 49, 2013: 1-6)

Four different starches, namely soluble starch, corn starch, potato starch and rice starch with different characteristics have been studied as depressants for hematite in cationic flotation using dodecylamine as the ...
A preliminary investigation into magnetic separation process using CFD (vol 24, pg 1651, 2011)

Mohanty, Swati; Das, B.; Mishra, B.K. (Minerals Engineering, 50-51, 2013: 143-143)
Removal of fluoride from aqueous solution and groundwater by wheat straw, sawdust and activated bagasse carbon of sugarcane

Yadav, A.K.; Abbassi, R.; Gupta, A.; Dadashzadeh, M. (Ecological Engineering, 52, 2013: 211-218)

The aim of this research work is to design and develop a novel cost effective strategy for fluoride removal, applicable to rural areas of developing countries. Most of the adsorbents based technologies for fluoride removal ...
Modeling and optimization of dye removal using "green" clay supported iron nano-particles

Abbassi, R.; Yadav, A.K.; Kumar, N.; Huang, S.; Jaffe, P.R. (Ecological Engineering, 61, 2013: 366-370)

This study addresses a process to produce green synthesized clay-supported nano-iron particles (CnIPs). Green tea was used to synthesize nano-particles supported on bentonite clay. Synthesized CnIPs were used for color ...
Role of cationic and anionic surfactants in textile dyeing with natural dyes extracted from waste plant materials and their potential antimicrobial properties

Baliarsingh, S.; Jena, J.; Das, T.; Das, N.B. (Industrial Crops And Products, 50, 2013: 618-624)

In the last few years, an increasing interest has been developed to the potential use of plant waste as raw material to produce natural dye for dyeing textiles due to environmental aspects. The current study deals with the ...
Manganese precipitation kinetics and cobalt adsorption on MnO2 from the ammoniacal ammonium sulfate leach liquor of Indian Ocean manganese nodule

Nathsarma, K.C.; Rout, P.C.; Sarangi, K. (Hydrometallurgy, 133, 2013: 133-138)

Precipitation of manganese from the SO2-roast leach ammoniacal ammonium sulfate solution bearing both high and low concentrations of manganese in the presence of copper, cobalt and nickel ions was carried out in a stainless ...
Extraction of Cu and Cr from a spent Cu-Cr catalyst: Recovery enhancement through mechanical activation

Swaroopa, S.; Ghosh, M.K.; Sanjay, K.; Mishra, B.K. (Hydrometallurgy, 136, 2013: 8-14)

Treatment process for a spent Cu-Cr catalyst (Cu 42.4% and 36.2% Cr) was described. The catalyst contained cuprous chromite (CuCrO2), cupric chromite (CuCr2O4) and copper sub-oxide (Cu8O) phases. High energy ball milling ...
