Turning Nd‐Fe‐B Swarf Into High‐Value Bulk Feedstocks via Sustainable Hydrogen Plasma: From Rare‐Earth Oxides to Metals and Hydrides

Advanced Materials, EarlyView.
Oxidized Nd‐Fe‐B magnet swarf is transformed into valuable bulk feedstock through a single‐step hydrogen plasma process. The reaction converts complex rare‐earth‐containing waste into separated metallic, oxide, and hydride fractions without acid leaching.

ROS Self‐Supply Nanoplatform Based on Fenton Catalyst for Chemodynamic and Immunotherapy: Reprogramming Cold Tumor Into Hot Tumor in Cancer Treatment

Advanced Science, EarlyView.
A multifunctional HA‐conjugated nanoplatform (HA‐PGMC) integrates CuO2, glucose oxidase, and mil‐100 to enable cascade catalytic ROS generation in tumor microenvironments. This self‐supplying ROS strategy induces immunogenic cell death, reprograms “cold” tumors into “hot” ones, and synergizes with PD‐L1 blockade, achieving potent chemodynamic ...

Determination of Mineral Content in Indian Spices by ICP-OES [PDF]

Oriental Journal of Chemistry, 2014
Vegetarian and non vegetarian Indian diet consists of various cereals and vegetables along with spices, often used in the preparation of curries. The nutritive potential of trace element has been evaluated using Inductively coupled plasma optical emission spectrometry (ICP-OES). In this study, 15 trace elements like As,Hg,Se,Zn,P,Pb,Cd,Fe,Mn,Cr,Mg,Cu,C,

Near‐Unity Selectivity Inversion Between CO2 Electroreduction and H2 Evolution via Atomic Coordination Editing

Advanced Science, EarlyView.
Atomic coordination editing functions as an on/off switch that toggles single‐atom catalysts between CO2 electroreduction and hydrogen evolution. ABSTRACT Precise atomic coordination editing of single‐atom catalysts (SACs) provides an effective strategy to tune their electronic structures and catalytic selectivity. Yet, achieving near‐unity selectivity

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

Advanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

Determination of Rare Earth Oxides in Bauxite by Inductively Coupled Plasma-Optical Emission Spectrometry

Yankuang ceshi, 2020
BACKGROUND When the rare earth oxides in bauxite are determined by inductively coupled plasma-optical emission spectrometry (ICP-OES), acid dissolution often results in incomplete dissolution of samples, and a large amount of fluxes at high temperature ...
