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 ... -
