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 extended Lorentz force

open access: yes, 2002
The Lorentz force equations provide a partial description of the geodesic motion of a charged particle on a four-manifold. Under the hypothesis that Maxwell's equations express symmetry properties of the Ricci tensor, the full electromagnetic connection is determined. From this connection, the fourth equation of the geodesic is derived. The validity of

Solvation Structure and Dynamics of the Thiocyanate Anion in mixed N,N‐Dimethylformamide‐Water Solvents: A Molecular Dynamics Approach

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The solvation structure and dynamics of the SCN− anion in mixed N, N‐Dimethylformamide (DMF)‐water liquid solvents is investigated using classical molecular dynamics simulations. A preferential solvation of SCN− by the water molecules is observed in the first hydration shell, followed by a second shell consisting by both DMF and water molecules.

Anisotropy Factor Spectra for Weakly Allowed Electronic Transitions in Chiral Ketones

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Anisotropy factor spectra for the weak n→π*‐type A‐band of chiral ketones cannot be described within the Franck–Condon approximation. Thus, we present such spectra computed by accounting for Herzberg–Teller corrections and compare them to experiments for fenchone, camphor and 3MCP to describe chiroptical properties of these molecules in the mid to near

Unraveling Mechanisms and Engineering Strategies for Superior Photocarrier Dynamics Toward Efficient Photocatalysis

open access: yesEcoEnergy, EarlyView.
Despite its potential, photocatalysis is limited by inefficient charge carrier separation and transport. This article reviews the mechanisms, characterization methods, and strategies for improvement, concluding with future challenges in the field. ABSTRACT Photocatalysis offers a promising solution to environmental and renewable energy issues. However,

Electrodynamics without Lorentz force

open access: yes, 2012
This communication is devoted to a brief historical framework and to a comprehensive critical discussion concerning foundational issues of Electrodynamics. Attention is especially focused on the events which, about the end of XIX century, led to the notion of Lorentz force, still today ubiquitous in literature on Electrodynamics.
