Structural Aspects of Lithium‐Ion Conduction in the Phosphidotitanate Li8TiP4 and Its Comparison With Li7+5xTa1−xP4 and Li8−xTi1−xTaxP4

Chemistry – A European Journal, EarlyView.
ABSTRACT The chemical system Li/Ti/P has previously been subject to intensive investigation. However, reliable structural data for the reported phases have remained elusive. Motivated by the growing interest in phosphorus‐based lithium‐ion conductors, we have reinvestigated the synthesis, crystal structure, and physical properties of Li8TiP4.

Effects of Surface Irregularities on Piston Ring-Cylinder Tribo Pair of a Two Stroke Motor Engine in Hydrodynamic Lubrication [PDF]

Tribology in Industry, 2015
Tribological parameters such as friction, lubrication and wear influence strongly the engine component's life. In this study, a piston ring-cylinder system simulated taking into account the surface modifications under fully flooded lubrication and normal

Experimental Parameter Study of the Factors Influencing Dry Dispersion Using Laser Diffraction

Chemie Ingenieur Technik, EarlyView.
Laser light diffraction reveals how geometric, material and operational factors govern dry dispersion efficiency and particle size distribution of submicron cathode material. The findings provide guidance for systematic optimization of powder handling and subsequent processing steps.

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

Chemie 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.

A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns

Chemie Ingenieur Technik, EarlyView.
Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.
