Production of Zinc Oxide nanorods and nano-platelets

Electronics / Electrical, Manufacturing, Metal oxide, Synthesis

The Challenge / Concern: Zinc Oxide (ZnO) is promising semiconductor material. Nanoscaled ZnO with varying but specific morphology was needed to be synthesized. Brief (and non-confidential) Solution A relatively low temperature controllable chemical bath deposition protocol was developed by the speculated growth mechanism of metal oxides. Synthesis of one dimensional ZnO nanorods and two dimensional …

Attenuator for harmonics in high voltage AC supply

Electronics / Electrical, Process

The Challenge / Concern: Variation in frequencies of power supply causes damage to electrical appliances as well as loss of performance. A compact attenuator was desired to mitigate harmonics in the AC electrical supply. Brief (and non-confidential) Solution Active and passive frequency filters were concerned. RL filters and simple inductive dampening was found of interest. …

Deposition of semiconductor array on metal oxide films

Electronics / Manufacturing, Metal oxide, Nanotech

The Challenge/Concern: A technique was desired for deposition of semiconductor quantum dots on metal oxide substrate. Brief (and non-confidential) Solution Techniques of self-assembled monolayer and chemical bath deposition were concerned and optimized for the materials of interest. Control on size of the dots, the coverage ratio and aspect ratio was optimized. A hybrid of both …
