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

Chemie Ingenieur Technik, Volume 98, Issue 7, Page 364-373, July 2026.
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.

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

Techno‐Economic Analysis of Hydrocarbon‐CO2 Binary Mixtures in Heat Pump‐Based Thermal Energy Storages

Energy Technology, Volume 14, Issue 4, April 2026.
Heat‐pump charging of Carnot batteries with zeotropic large temperature glide CO2–alkane mixtures enables charging from ambient to ≈398.15 K with improved heat‐exchanger temperature matching at moderate pressure ratios. The highest COP occurs near xCO2 ≈ 0.15, whereas cost and throttling losses rise monotonically with CO2 content; butane isomers ...
