Line focus solar concentrating collector systems of the parabolic trough type with single axis tracking are being increasingly used for Industrial Process Heat (IPH) applications such as the production of process steam and ... -
Amorphous hydrogenated silicon microstructure analysis and effect of plasmons on solar cell performance
Hydrogenated amorphous silicon (a?Si:H), a well?known material for photovoltaics, thin?film transistors, MEMS, etc., is most extensively deposited using the PECVD technique, which is well studied and is primarily used in ... -
Study of electromechanical and optoelectronic behavior of carbon nanostructures
Electric field induces a large actuation (up to 14-30%) in bulk CNT cellular structure. The actuation is symmetric, polarity independent, non-instantaneous, and directly proportional to the square of the applied electric ... -
Rotating cruicible electron beam evaporation technique for mixed oxide films
Recent developments in thin film deposition techniques for preparing a variety of devices such as superconducting films, optical interference coatings, solar selective coatings, etc., have shown the necessity of preparing ... -
Studies in the polarographic behaviour
A detailed investigation on the polarographic (d.c., a.c. and complex plane) and microcoulometric behaviour of m‑, o‑ and p‑nitrophenols in aqueous and 40% ethanolic solutions at various pH values is presented. In the ... -
Development of a Two-LED based Smartphone Footprint device for Sickle Cell Anemia and Hemoglobin Estimation
Anemia is a serious health concern worldwide, with sickle-cell anemia leading to more severe illness and higher mortality. Globally, sickle-cell disease has historically been associated with very high early-childhood ... -
Characterization of Quality Factors of Superconducting Resonators
Superconducting lumped element resonators play a pivotal role in circuit quantum electrodynamics (cQED) architectures, serving both as protective filters that isolate qubits from environmental noise and as sensitive probes ... -
