Characterization of novel Cs and K substituted phosphotungstic acid modified MCM-41 catalyst and its catalytic activity towards acetylation of aromatic alcohols

Rana, S.; Mallick, S.; Rath, D.; Parida, K.M. (Journal Of Chemical Sciences, 124(5), 2012: 1117-1125)

The MCM-41 supported Cs2.5H0.5PW12O40 and K2.5H0.5PW12O40 salts were synthesized by incipient wetness impregnation method. The solids were characterized by N-2 adsorption-desorption isotherms, FT-IR, XRD, and temperature ...
Incorporation of Fe3+ into Mg/Al layered double hydroxide framework: effects on textural properties and photocatalytic activity for H-2 generation

Parida, K.; Satpathy, M.; Mohapatra, L. (Journal Of Materials Chemistry, 22(15), 2012: 7350-7357)

This present work highlights the successful preparation of the ternary series of (Mg/Al + Fe)-CO3 layered double hydroxides with a constant ratio of Mg/(Al + Fe) 2 : 1 and their application for photocatalytic hydrogen ...
Exploring sustainable technique on natural dye extraction from native plants for textile: identification of colourants, colourimetric analysis of dyed yarns and their antimicrobial evaluation

Baliarsingh, S.; Panda, A.K.; Jena, J.; Das, T.; Das, N.B. (Journal Of Cleaner Production, 37, 2012: 257-264)

Use of natural dyes in textile colouration is gaining popularity all over the world during the last decade. The current study deals with solvent extraction of natural dyes from two plant species (Saraca asoca and Albizia ...
Extraction of nickel by microbial reduction of lateritic chromite overburden of Sukinda, India

Behera, S.K.; Panda, S.K.; Pradhan, Nilotpala; Sukla, L.B.; Mishra, B.K. (Bioresource Technology, 125, 2012: 17-22)

Microbial extraction of nickel from lateritic chromite overburden (COB), Sukinda by Acidithiobacillus ferrooxidans has been investigated in this work. In anoxic environment, A. ferrooxidans reduced the ferric iron in ...
Experimental investigation on an entrained flow type biomass gasification system using coconut coir dust as powdery biomass feedstock

Senapati, P.K.; Behera, S. (Bioresource Technology, 117, 2012: 99-106)

Based on an entrained flow concept, a prototype atmospheric gasification system has been designed and developed in the laboratory for gasification of powdery biomass feedstock such as rice husks, coconut coir dust, saw ...
Microbial extraction of nickel from chromite overburdens in the presence of surfactant

Behera, S.K.; Sukla, L.B. (Transactions Of Nonferrous Metals Society Of China, 22(11), 2012: 2840-2845)

The effect of surfactant polyoxyethylenesorbitan monolaurate (Tween-20) on the nickel bioleaching from pre-treated chromite overburden (COB), Sukinda with fungal strain Aspergillus niger, was examined in shake flasks. Along ...
Hg(II) ion specific dual mode signalling in a thiophene derivatized rhodamine based probe and their complexation cooperativity

Pal, A.; Bag, B. (Journal Of Photochemistry And Photobiology A-Chemistry, 240, 2012: 42-49)

The rhodamine based chemosensor 1 exhibited highly selective and sensitive detection of Hg(II) ion in MeCN-H2O mixture observable through amplified absorption and emission signals with a colour change from colourless to ...
Zn-Cr layered double hydroxide: Visible light responsive photocatalyst for photocatalytic degradation of organic pollutants

Mohapatra, L.; Parida, K.M. (Separation And Purification Technology, 91, 2012: 73-80)

Heterogeneous photocatalysis, one of the important steps in advanced oxidative process (AOPs) that was found to be promising for the elimination of toxic organic and inorganic compounds from wastewater. Herein, we reported ...
Carbonate intercalated Zn/Fe layered double hydroxide: A novel photocatalyst for the enhanced photo degradation of azo dyes

Parida, K.M.; Mohapatra, L. (Chemical Engineering Journal, 179, 2012: 131-139)

Zn/Fe layered double hydroxides with different intercalated anions (nitrate, chloride and carbonate) as visible-light response photocatalysts were fabricated by co-precipitation method. The as-prepared LDH photocatalysts ...
Dramatic enhancement of catalytic activity over transition metal substituted hematite

Pradhan, G.K.; Parida, K.M. (Journal Of Industrial And Engineering Chemistry, 18(5), 2012: 1612-1619)

paper reports the fabrication of hematite (alpha-Fe2O3) and its mixed oxides (alpha-Fe2-xO3Cux, alpha-Fe2-xO3Cox, alpha-Fe2-xO3Nix) by hydrothermal technique without using any surface directing agent or capping agent. The ...
