Article Synopsis
- Nickel pyrovanadate (NVO) and reduced graphene oxide (rGO) are synthesized together using a solvothermal method, resulting in a crystalline NVO structure and amorphous rGO within the nanocomposite.
- The formation of a hollow nanosphere shape for NVO is observed, which improves surface area and electrochemical stability due to the rGO incorporation.
- The NVO@rGO 20 composite achieves a specific capacitance of 3807 F/g and retains about 70% of its capacitance after 10,000 cycles, making it a promising candidate for high-performance energy storage devices.
In this study, bismuth ferrite (BFO) and copper-added BFO were synthesized using the coprecipitation method. The incorporation of copper into the BFO lattice led to a reduction in the phase percentage of BFO due to the early formation of CuBiO. X-ray diffraction analysis revealed a decrease in crystallite size up to 0.

Two kinds of heterostructure NW light-emitting diodes (LEDs) have been fabricated: (1) 10 pairs of InGaN/GaN MQW layers in the c-plane on the top of n-GaN NWs where Mg-doped p-GaN NW is axially grown (2) p-GaN/10 pairs of InGaN/GaN shell structure were surrounded by n-GaN core. Here, we discuss a comparative analysis based on the m-plane and the c-plane oriented InGaN/GaN MQW NW arrays.
