A "Two-Step" Electrochemical Approach for Recovery of Plutonium and Uranium from Aqueous Acidic Waste Solutions.

Chemical quality control of nuclear fuel, particularly the determination of Pu and U contents by chemical methods, results in analytical acidic aqueous waste solutions from which Pu and U must be recovered efficiently for the remediation of radioactive wastes. Reported methods involve several complicated steps requiring addition of chemical oxidants/reductants for valence adjustments and generation of secondary wastes, thereby making the recovery process cumbersome. Herein, we report a novel two-step electrochemical approach for Pu and U recovery from acidic aqueous waste solutions containing different metallic impurities (Fe, Cr, Mn, Cd, Al, Ni, Co, Zn, and Mg) by bulk electrolysis using a Pt gauze electrode.

Synthesis and feasibility studies of doping U at Ti site of YTiO as a radioactive waste immobilization matrix.

In pursuit of clean and green nuclear energy one of the major challenges is to effectively immobilize the nuclear waste. In this context ABO type pyrochlore owing to its structural flexibility, ability to accommodate ions at both A/B-sites and high radiation tolerance has demonstrated excellent capability to store highly radioactive actinide ions. To fill the major gap area of actinide doping at the B site we have taken up the challenge of doping uranium ions at the Ti site of YTiO type pyrochlore.

ADVANCING THE UNDERSTANDING OF CLINICAL SEPSIS USING GENE EXPRESSION-DRIVEN MACHINE LEARNING TO IMPROVE PATIENT OUTCOMES.

Sepsis remains a major challenge that necessitates improved approaches to enhance patient outcomes. This study explored the potential of machine learning (ML) techniques to bridge the gap between clinical data and gene expression information to better predict and understand sepsis. We discuss the application of ML algorithms, including neural networks, deep learning, and ensemble methods, to address key evidence gaps and overcome the challenges in sepsis research.

Crystal Structure and Site Symmetry of Undoped and Eu Doped Ba LaSbO and BaLaMSbO Compounds (M=Mg,Ca): Tuning Europium Site Occupancy to Develop Orange and Red Phosphor.

Double perovskite antimonates of the type BaLaMSbO (M=Mg, Ca) were synthesized by a standard solid-state route. The compounds were characterized by X-ray crystallography and the structures were refined using Rietveld method. BaLaMgSbO and BaLaCaSbO crystallized in monoclinic space groups (I2/m) and (P2 /n), respectively.

Crystal structure of Ba(LaBaM)MO (M = Nb, Sb, Bi): symmetry nuance identified in photoluminescence and IR spectroscopy studies.

A one-third lanthanum deficiency was created in BaLaMO compounds (LaM compounds) to form BaLaMO compounds (La2/3M compounds) for M = Nb, Sb, and Bi. The compounds were prepared by a gel-combustion method using citric acid as a fuel. All the compounds were characterized by powder X-ray diffraction (XRD).
