Redox control in a pilot flotation column
, 1996 Results from pilot-column flotation tests on a lead-zinc ore show that it is possible to control the redox potential of the column pulp by varying the oxygen activity of the flotation gas fed to the spargers.

Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area
Batteries &Supercaps, Volume 8, Issue 3, March 2025.Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.

Asymmetric Dialysis: Truly Unified and Simultaneous Single‐Pass Concentration and Buffer Exchange
Biotechnology and Bioengineering, EarlyView.Asymmetric dialysis, a novel one‐step continuous process combining ultrafiltration and diafiltration, achieves high product concentrations (up to 200 g/L) with low pressures and reduces buffer consumption by 75% compared to conventional methods. This sustainable, low‐cost technology demonstrates significant potential for integration into continuous ...
