The role of nitrogen on the flotation performance of a complex sulphide ore [PDF]
, 2000 Bibliography: leaves 94-99.This thesis focuses on the role of nitrogen on flotation performance of a sulphide PGM ore. Merensky ore obtained from Impala Platinum mine, Rustenburg, was used in laboratory batch flotation tests.

Flotation of Chromium Ions from Simulated Wastewater Using Air Microbubbles
Iraqi Journal of Chemical and Petroleum Engineering, 2023 A microbubble air flotation technique was used to remove chromium ions from simulated wastewater (e.g. water used for electroplating, textiles, paints and pigments, and tanning leather).

Engineering IL‐4 resistant proinflammatory human myeloid cells for cancer immunotherapy
Molecular Oncology, EarlyView.We developed a scalable workflow to generate proinflammatory human myeloid cells. CRISPR/Cas9‐edited CD34+ hematopoietic stem and progenitor cells were expanded and differentiated with M‐CSF. Deletion of STAT6 or STAT6/NFKB1 enhanced macrophage proinflammatory gene expression and cytokine secretion in the presence of IL‐4 while maintaining antibody ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Hydrogel platforms for 3D cardiac tissue engineering and fibrotic disease modelling
FEBS Open Bio, EarlyView.Hydrogel‐based cardiac tissue models are advancing our understanding of heart health and disease. By incorporating electrical conductivity, aligned structures, and tunable mechanical properties, these platforms better replicate the complex environment of native heart tissue.
