Nanotechnology and nanomedicine: going small means aiming big.

Abstract: Nanotechnology is an emerging branch of science for designing tools and devices of size 1 to 100 nm with specific function at the cellular, atomic and molecular levels. The concept of employing nanotechnology in biomedical research and clinical practice is best known as nanomedicine. Nanomedicine is an upcoming field that could potentially make a major impact to human health. Nanomaterials are increasingly used in diagnostics, imaging and targeted drug delivery. Nanotechnology will assist the integration of diagnostics/imaging with therapeutics and facilitates the development of personalized medicine, i.e. prescription of specific medications best suited for an individual. This review provides an integrated overview of application of nanotechnology based molecular diagnostics and drug delivery in the development of nanomedicine and ultimately personalized medicine. Finally, we identify critical gaps in our knowledge of nanoparticle toxicity and how these gaps need to be evaluated to enable nanotechnology to transit safely from bench to bedside.

Diesel Engine Emission Reduction Using Catalytic Nanoparticles: An Experimental Investigation

Abstract: Cerium oxide being a rare earth metal with dual valance state existence has exceptional catalytic activity due to its oxygen buffering capability, especially in the nanosized form. Hence when used as an additive in the diesel fuel it leads to simultaneous reduction and oxidation of nitrogen dioxide and hydrocarbon emissions, respectively, from diesel engine. The present work investigates the effect of cerium oxide nanoparticles on performance and emissions of diesel engine. Cerium oxide nanoparticles were synthesized by chemical method and techniques such as TEM, EDS, and XRD have been used for the characterization. Cerium oxide was mixed in diesel by means of standard ultrasonic shaker to obtain stable suspension, in a two-step process. The influence of nanoparticles on various physicochemical properties of diesel fuel has also been investigated through extensive experimentation by means of ASTM standard testing methods. Load test was done in the diesel engine to investigate the effect of nanoparticles on the efficiency and the emissions from the engine. Comparisons of fuel properties with and without additives are also presented.

Optimal Operation of Biomass/Wind/PV Hybrid Energy System for Rural Areas

Abstract: In this article, a hybrid energy system consisting of biomass, wind, solar photovoltaic (SPV), and battery is proposed. The sources are operated to deliver energy at optimum efficiency. An optimization model is developed to supply the available energy to the loads according to the priority. It is also proposed to maintain a fair level of energy storage to meet the peak load demand together with biomass, wind, and solar photovoltaic during low or no solar radiation periods or during low wind periodsA case study was completed using load data collected from three villages (300 km south of Chennai, India). Simulations carried out for a one-year period proved the effectiveness of the developed energy management system by satisfying the load demand, nonlinear seasonal variations, and equipment constraints. Also with the proposed energy management, it is found that the load demand is almost satisfied, there is less dumped energy, and the state of charge of the battery is at a reasonably good level.
