For a long time, transition metal oxide systems have been considered well explored materials in heterogeneous catalysis. Amongst, the spinel-type oxides, such as cobaltites (Co3O4) received significant attention, owing to their use many industrial applications. In present study, nanosized Cu, Ni, and Zn cobaltite spinel oxides were synthesized by simple hydrothermal method. Physicochemical char...

Excess use of chemical pesticides in agriculture assisting the accomplishment of agri-food production targets. But, indiscriminate use of chemical pesticide is the serious concern for environment and human, which deteriorating the soil health, nutritional quality of food and increasing resistance in phyto-pathogens and pests. Nanotechnology provided the sustainable solution in this regard by de...

In this work, we investigate the possibility of using double cobaltite with composition PrBaCo2O6 as an electrocatalyst in oxidation organic compounds. A screen-printed carbon electrode modified drop method was investigated a sensor for glucose. The amperometric signal is logarithmically dependent on analyte concentration according to equation: I (μA) = 9.485⋅ln(C (mM)) + 17.864 (R 0.9951). lim...

Tailoring materials to obtain unique, or significantly enhanced material properties through rationally designed structures rather than chemical constituents is principle of metamaterial concept, which leads to the realization of remarkable optical and mechanical properties. Inspired by the recent progress in electromagnetic and mechanical metamaterials, here we introduce the concept of ferroele...
