Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

open access: yesChemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Application of Ultrasonic Sensors for Determining the Height of Dynamic Two‐Phase Layers in Tray Columns

open access: yesChemie Ingenieur Technik, EarlyView.
Ultrasonic sensors are evaluated for their applicability in dynamic gas–liquid systems. By comparing sensor data with two independent optical reference methods, their robustness and reliability are demonstrated under varying flow conditions and tray geometries in column systems.

Characterization of a two‐phase hybrid flotation column

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study explored the performance of a novel hybrid flotation column, which combines the advantages of a mechanically agitated cell with a flotation column and compared the results with a conventional flotation column setup. The experiments were performed in an air/water two‐phase system under varying airflow rates, frother concentrations ...

Environmental Dynamism and Supply Chain Responsiveness Nexus: Do Organisational Improvisation and Supply Chain Orientation Matter?

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The crucial role of environmental dynamism (ED) in achieving supply chain responsiveness (SCR) has become a controversial topic in extant literature. However, despite several empirical studies on environmental dynamism and supply chain responsiveness, inconsistent findings and underexplored areas leave supply chain managers less informed about

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.
