2015 Journal Article S. K. Mahadeva and Debjyoti Sahu, “Effect of iron oxide nanoparticle in bio digestion of a portable food-waste digester”, Journal of Chemical and Pharmaceutical Research, vol. 7, pp. 353-359, 2015.[Abstract]

Handling of wasted food product is a challenging task in municipal solid waste management. Dumping fast degradable material to landfills generates greenhouse gases as well as foul smell. Such biodegradable waste can be processed scientifically to obtain useful products. By utilizing these wastes in an anaerobic digester, biogas rich with methane gas (upto 60%) is generated and the residue slurry is used as organic fertilizer. It is the best means to deal with food/organic waste in rural as well as urban areas. Performance analysis of anaerobic digesters is reported in the literature since last few decades. Bio digestion involves slow chemical reactions. It is well reported in literature that high retention time makes this system less attractive. Additional iron content in the digestion process increases the production rate as it helps in reducing CO2 to form CH4. Increase in methane quantity increases the quality of biogas. Since pure iron may generate toxic free radicals in the system additional iron oxides powders are used. Generally nanoparticles catalyzes better than its bulk analogs. Bio degradable iron oxide nanoparticles produced by polyol method is added to the digester to enhance the rate of production. More »»
2014 Journal Article Debjyoti Sahu, Mishra, P., DAS, N. I. T. U. N., Verma, A., and Gumma, S., “THE NET ADSORPTION OF HYDROGEN ON PALLADIUM NANOPARTICLES”, Surface Review and Letters, vol. 21, p. 1450022, 2014.[Abstract]

In this paper, we report the synthesis of polymer coated palladium (Pd) nanoparticles through a single stage reduction of Pd2+ ions by ethylene glycol. Polyvinyl pyrrolidone (PVP, MW 25,000) is used as a stabilizer. Self-assembled Pd nanoparticles (10–40 nm) were used in hydrogen adsorption studies. Gravimetric adsorption measurements were carried out in a pressure range of 0–26 bar at 293, 324, 364 and 392 K. Saturation for all isotherms was obtained within a few bars of pressure at all temperatures. Maximum hydrogen storage capacity observed was 0.58 wt.% at 324 K and 20 bar. Net adsorption calculations indicated that required tank volume (for storing a particular amount of hydrogen) can be significantly reduced by using a tank filled with Pd nanoparticle.

2013 Journal Article Debjyoti Sahu, Mishra, P., Edubilli, S., Verma, A., and Gumma, S., “Hydrogen Adsorption on Zn-BDC, Cr-BDC, Ni-DABCO, and Mg-DOBDC Metal–Organic Frameworks”, Journal of Chemical & Engineering Data, vol. 58, pp. 3096–3101, 2013.[Abstract]

This work reports hydrogen adsorption properties of four different metal–organic frameworks (MOFs) namely Zn-BDC, Cr-BDC, Ni-DABCO, and Mg-DOBDC. Gravimetric hydrogen adsorption measurements are performed over a wide range of temperature (90 K to 298 K) and pressure (0 bar to 100 bar). At the lowest experimental temperature (90 K to 100 K) all the isotherms are saturated and the adsorption capacity is governed by pore volume. On the other hand, at room temperature the isotherms closely follow Henry’s law. Modeling of the excess isotherms is also done. Net adsorption isotherms, which can directly indicate the efficiency of porous adsorbent for storage, are also presented. In terms of volumetric efficiency, Mg-DOBDC MOF exhibits best storage capacity out of all the MOFs considered in this study.
