Biotechnology Progress, EarlyView.Abstract High performance countercurrent membrane purification (HPCMP) has emerged as a promising diffusive separation strategy for the purification of recombinant proteins and monoclonal antibodies (mAbs). However, prior studies employed dialysis membranes, which are designed for diffusive separations but have not been validated for biopharmaceutical ...

Large-scale flow model for solar and stellar convection zones
Solnechno-Zemnaya FizikaThe paper presents a mean-field model for large-scale flows in convection zones of the Sun and solar-type stars. The model extends former differential rotation models by allowance for variations of the flow with time and its deviation from axial symmetry.

Beyond Furnaces: Harnessing In Situ Joule Heating for Efficient C1 Catalysis
Carbon Energy, EarlyView.Joule‐heated catalysis directly converts electrical energy into localized heat within conductive catalysts, overcoming the heat‐transfer limitations of conventional furnaces. This review summarizes recent advances in C1 molecule conversion, including CO2 methanation, reforming for hydrogen production, and HCHO/CO oxidation, while highlighting ...

An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading
Chemie Ingenieur Technik, EarlyView.A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

Selective Non‐Catalytic Reduction of NOx in the Exhaust Gas of Small Wood Gasification Boilers
Chemie Ingenieur Technik, EarlyView.Kinetic studies of the SNCR reaction were conducted to investigate NOx reduction in the exhaust gas of small‐scale wood gasification boilers. Both the experimental results and the derived global kinetic model indicate that SNCR can achieve a significant reduction in NOx emissions under typical operating conditions. ABSTRACT The gas‐phase reaction of NO
