Cytotoxic Effect of Microbial Biosurfactants Against Human Embryonic Kidney Cancerous Cell: HEK-293 and Their Possible Role in Apoptosis

Pradhan, A.K.; Pradhan, Nilotpala; Mohapatra, P.; Kundu, C.N.; Panda, P.K.; Mishra, B.K. (Applied Biochemistry And Biotechnology, 174(5), 2014: 1850-1858)

Two different microbial biosurfactants S9BS and CHBS were isolated from Lysinibacillus fusiformis S9 and Bacillus tequilensis CH. Cytotoxicity effect of these biosurfactants on human embryonic kidney cancerous cell (HEK-293) ...
Cs salt of tungstophosphoric acid-promoted zirconium titanium phosphate solid acid catalyst: An active catalyst for the synthesis of bisphenols

Biswal, N.; Das, D.P.; Parida, K. (Journal Of Chemical Sciences, 126(2), 2014: 455-465)

A series of novel xCsTPA-ZTP (x = 30, 40, 50, 60 and 80 wt%) solid acid composite catalysts were synthesized by ion-exchange process using cesium nitrate, tungstophosphoric acid (TPA), zirconium titanium phosphate (ZTP) ...
Degradation Mechanism and Control of Blended Eri and Tasar Silk Nanofiber

Panda, N.; Biswas, A.; Sukla, L.B.; Pramanik, K. (Applied Biochemistry And Biotechnology, 174(7), 2014: 2403-2412)

Fabrication of nanofibers from wild varieties of silk such as eri and tasar is very promising for tissue engineering application because of the presence of RGD (arginine-glycine-aspartic acid) ligand and high content of ...
A systematic study on the effect of acidic, basic and neutral additives on dispersion of multiwalled carbon nanotubes using a dimethylformamide solution

Nayak, S.; Bhattacharjee, S.; Singh, B.P. (Advances In Natural Sciences-Nanoscience And Nanotechnology, 5(4), 2014)

Presence of acidic, basic and neutral additives on dispersion of multiwalled carbon nanotubes (MWCNTs) in dimethylforamide (DMF) solution has been investigated. The surface charge measurement showed that MWCNTs in the ...
Structural refinement, optical and ferroelectric properties of microcrystalline Ba(Zr0.05Ti0.95)O-3 perovskite

Badapanda, T.; Sarangi, S.; Behera, B.; Sahoo, P.K.; Anwar, Shahid; Sinha, T.P.; Luz, G.E.; Longo, E.; Cavalcante, L.S. (Current Applied Physics, 14(5), 2014: 708-715)

For this study, a microcrystalline Ba(Zr0.05Ti0.95)O-3 (BZT) powder was prepared by a high energy ball milling method followed by calcination at 1100 degrees C for 4 h. The calcined powder was structurally characterized ...
Functional link artificial neural network applied to active noise control of a mixture of tonal and chaotic noise

Behera, S.K.; Das, D.P.; Subudhi, B. (Applied Soft Computing, 23, 2014: 51-60)

Many practical noises emanating from rotating machines with blades generate a mixture of tonal and the chaotic noise. The tonal component is related to the rotational speed of the machine and the chaotic component is related ...
Nonlinear feedback active noise control for broadband chaotic noise

Behera, S.B.; Das, D.P.; Rout, N.K. (Applied Soft Computing, 15, 2014: 80-87)

Feedback active noise control has been used for tonal noise only and it is impractical for broadband noise. In this paper, it has been proposed that the feedback ANC algorithm can be applied to a broadband noise if the ...
Effect of urea on decomposition of sodium aluminate solution

Sahu, N.K.; Sarangi, C.K.; Tripathy, B.C.; Bhattacharya, I.N.; Satpathy, B.K. (Journal Of The Taiwan Institute Of Chemical Engineers, 45(3), 2014: 815-822)

Aluminium hydroxide particles were synthesized from sodium aluminate liquor by urea decomposition method at elevated temperatures in presence and absence of seed. Different parameters such as alumina to caustic (A:C) ratio, ...
Structural and impedance spectroscopy study of Samarium modified Barium Zirconium Titanate ceramic prepared by mechanochemical route

Badapanda, T.; Sarangi, S.; Behera, B.; Anwar, Shahid (Current Applied Physics, 14(9), 2014: 1192-1200)

Samarium modified Barium Zirconium Titanate (BZT) ceramics with general formula [Ba1-xSm2x/3](Zr0.05Ti0.95O3) [x = 0, 0.01, 0.02, 0.03 and 0.04] have been prepared by high energy ball milling. The Rietveld refinement of ...
A Taguchi optimization of cooling slope casting process parameters for production of semi-solid A356 alloy and A356-5TiB(2) in-situ composite feedstock

Kumar, S.D.; Vundavilli, P.R.; Mantry, Sisir; Mandal, A.; Chakraborty, M. (International Conference On Advances In Manufacturing And Materials Engineering (Icamme 2014), 5, 2014: 232-241)

The cooling slope technique is the oncoming semi-solid process. The primary objective of this research is to optimize the process parameters of the cooling slope casting process and to generate the semi-solid feedstock ...
