Direct Capture of Dynamic Surface Reconstruction in a Perovskite Cathode via Operando Raman Spectroscopy

open access: yesCarbon Energy, EarlyView.
Operando Raman spectroscopy directly captures the dynamic form conditions of the BaCoO3‐δ phase on the BSCY surface. This observation provides critical insight into the phase evolution mechanisms, which are essential for optimizing the performance and stability of BSCY‐based protonic ceramic fuel cell cathodes.

High‐Temperature Heat Pump Test Bench with n‐Butane (R‐600) Generating Steam

open access: yesChemie Ingenieur Technik, EarlyView.
This work involves building a test bench for a high‐temperature heat pump (HTHP) and analyzing the measurements. The focus is on steam generation using an HTHP to decarbonize process steam demand. The findings indicate that stable steam generation is possible, providing a higher heat transfer coefficient in the heat pump's condenser.

The Effect of Temperature on Refining [PDF]

open access: yes, 1972
The results of this work indicate that elevated beating temperature drastically increases beating time and produces detrimental effects on the physical characteristics of the formed sheet as evaluated by wet web strength, tear and tensile.

A Short‐Cut Design Approach to Evaluate Reboiler Designs in Vapor Recompression Scenarios

open access: yesChemie Ingenieur Technik, EarlyView.
A short‐cut model framework that incorporates mechanical vapor recompression (MVR) requirements into reboiler design is presented, which is particularly beneficial during early process development with limited data or initial feasibility assessments.

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.
