Luminescent ZnSe/ZnO Heterostructures for Photocatalytic Degradation of Azophloxine Dye and Bioimaging Applications.

Herein, we demonstrate a simple hydrothermal route to synthesizing ZnSe/ZnO type II heterostructure using L-cysteine as a capping agent. The use of nanomaterials in bioimaging and photocatalysis towards the degradation of Azophloxine dye is of potential interest. The synthesized ZnSe/ZnO nanomaterials were characterized by UV-Vis absorption spectroscopy, fluorescence spectroscopy, IR spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy.

A novel dual hysteresis controller for the management of a three phase dynamic voltage restorer.

In this work a novel control scheme for the three-phase dynamic voltage restorer has been proposed and validated. The proposed control strategy guarantees the source current waveform to be sinusoidal and at near unity power factor. Further, the voltage sag and swell occurring in the source are overcome and the load gets a smooth power supply at a voltage closer to the rated voltage even in the face of voltage sag or swell occurring in the source.

Catechol-derived Mannich bases: radical regulatory properties, cytotoxicity and interaction with biomolecules.

Free radicals are ubiquitous in biological systems, being responsible for pathogenesis of degenerative diseases and participating in vitally important biochemical processes, which are mediated by radical regulatory agents. The effects of the aliphatic amine substituents in the catechol-derived Mannich bases on their antioxidant and pro-oxidant activity were investigated. It has been found that the presence of catechol moiety in the structure of Mannich bases allows them to act as Cu(II) reductants, efficient Fe(II) chelators and potent DPPH radical scavengers.

Evaluating the Crossmatch-to-Transfusion Ratio as a Tool for Analyzing and Optimizing Blood Bank Resource Utilization: A Retrospective Observational Study.

Background Blood transfusion services are crucial for modern medical care, particularly for surgical interventions, chronic diseases, pregnancy complications, and malignancies. There is an increasing demand for blood products in India; hence, optimizing resource utilization in blood banks is essential. This study aims to evaluate the crossmatch-to-transfusion (C/T) ratio as a tool for analyzing and optimizing the utilization of blood bank resources.

Impact of Type and Screen Method on Turnaround Time and Man-Hour Utilization Compared to Conventional Coomb's Crossmatch: A Cross-Sectional Analytical Study.

Background Blood component transfusion is vital for various medical conditions, requiring thorough pretransfusion testing to ensure safety and compatibility. The Type and Screen (T and S) method allows for efficient detection of clinically significant antibodies while reducing unnecessary crossmatching. This study evaluates T and S's impact on turnaround time and man-hour utilization compared to conventional crossmatching.
