Multicomponent nanoparticles containing two or more different types of functionalities show unique physical and chemical properties, leading to significantly enhanced performance. In this study, we have developed a new one-pot method to prepare Fe/FeS nanoparticles using dithionite at room temperature. The FeS precipitates on the Fe surface are formed by(More)
Surgical site infections caused by methicillin-resistant and methicillin-susceptible Staphylococcus aureus (MRSA, MSSA) lead to patient hospitalization for an extended period coupled with concomitant hospitalization resources and cost. The detrimental effect resulting from the onset of these infections poses great health risks, leading to death in some(More)
High selectivity, enhanced sensitivity, short response time and long shelf-life are some of the key features sought in the solid-state ceramic-based hemical sensors. Since the sensing mechanism and catalytic activity are predominantly surface-dominated, benign surface features in terms f small grain size, large surface area, and open and connected porosity,(More)
High selectivity, enhanced sensitivity, short response times and long shelf-life are much sought-after features in solid-state chemical sensors for the detection and metering of gas(es) of interest. Because the sensing mechanism of semiconducting oxides is invariably surface dominated, benign microscopic features are desirable to realize a useful sensing(More)
The chemical-looping combustion (CLC) and chemical-looping with oxygen uncoupling (CLOU) processes are attractive solutions for efficient combustion with direct separation of carbon dioxide. In this work, the feasibility of CuO supported on Al2O3 andMgAl2O4 for CLC and CLOU processes is investigated. The oxygen carriers were produced by freeze-granulation(More)
An economically viable and environmental-friendly method of generating PEM grade hydrogen has been proposed and is by the reaction of certain metals with steam, appropriately called ‘metal–steam reforming’—MSR. The drawbacks of conventional processes (hydrogen and carbothermic reduction schemes) are overcome by resorting to solution-based reduction schemes(More)
Employing a buffer gas mixture of CO and CO2, the equilibrium oxygen partial pressure was varied across the Mo/MoO3 proximity line by arying the ratio of concentration of the two gases, as described in an earlier communication. This led to the reduction of MoO in one case and 3 xidation of the reduced phase (Mo or MoO2) in the other with a concomitant(More)
