Multi-scale interfacial mechanisms of Pb immobilization in contaminated soil using phosphoric acid-activated coal gangue-electrolytic manganese residue geopolymers

Journal of Rock Mechanics and Geotechnical Engineering
The accumulation of contaminated soils and solid waste stockpiles has led to significant resource wastage and environmental pollution. This study investigates a novel solidification/stabilization (S/S) curing agent, named ECPG, synthesized from ...

Effect of Cyclic Lateral Loading on the Compaction Behaviour of Waste Rock Backfill Materials in Coal Mines

Energies, 2018
Crushed waste rock (CWR) can be used as backfill for goafs allowing disposal of solid waste and control of surface subsidence. Waste rocks for backfilling (WRBs) have a certain density before use if cyclic lateral loads are applied to CWRs, therefore, by

Anisotropic thermal properties of an argillaceous rock under elevated temperatures and external load conditions

Case Studies in Thermal Engineering, 2023
The design and long-term safety of geological repositories for high-level radioactive waste (HLW) are dependent on the precise determination of the thermophysical parameters of mudstone.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Chitin‐Derived Carbon‐Metal Functional Materials

Advanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Recycling Process of Copper and Cobalt Waste Rock in the Democratic Republic of the Congo

Kuangchan zonghe liyong
The copper grade of the waste rock in the Sicomines copper-cobalt mining area in Congo (DRC) is 1.01%, and the cobalt grade is 0.045%, which has the recycling value. However, the waste rock has problems of high oxidation rate and severe mudding.

Mechanochemical Defluorination of Polytetrafluoroethylene (PTFE) With Base Metals

Angewandte Chemie, EarlyView.
Polytetrafluoroethylene (PTFE) mechanochemically reacts with safe‐to‐handle, abundant, and inexpensive base metals Zn and Al, as well as with metals like Cd and Pb, to produce sp2‐carbon and industrially important metal fluorides. The reactivity presents PTFE as a mechanochemical fluorination agent, with opportunities for closed‐loop reductive ...
