Crystal Structures, Raman Spectra, and Thermal Analysis of Cobalt(III) Ammine Coordination Compounds in the Context of Battery Materials

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 6, 07 April 2026.
A series of Co(III) ammine coordination compounds, which are potential precursors for battery materials, were synthesized and characterized by X‐ray diffraction, Raman spectroscopy, and thermal analysis. These methods provide complementary insight into structural motifs and decomposition behavior as well as an easy way to identify Co(III) complexes ...

The Investigation on Rheology and Microstructure for Lithium Complex Grease

Energy and Earth Science, 2019
The rheological characteristic parameters of five lithium complex lubricating greases were determined. The comparison of rheological characteristic parameters and microstructure of the five greases was made. The results showed that the knowledge of the rheological properties of lubricating greases may contribute to reflect the change of the thickener ...

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, Volume 32, Issue 13, 1 April 2026.
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.

Steady-State Flow Characteristics and End Clearance Optimization of Internal Gear Grease Pump

Advances in Materials Science and Engineering, 2021
The internal gear grease pump is a mechanical device used for transfer of high viscosity fluid. The existing clearance between the end faces of the internal or external gear and the floating side plate might cause pump leakage during operation.

A Nongassing Online Electrochemical Mass Spectrometry Strategy for Isolating Electrode‐Derived Gas Evolution in Sodium‐Ion Batteries

Small Structures, Volume 7, Issue 4, April 2026.
The schematics illustrates a nongassing online electrochemical mass spectrometry approach that suppresses electrolyte‐derived species and cross talk, enabling direct attribution of gas evolution to carbon at high potentials. Scanning electron microscope images highlight distinct carbon morphologies, and the method reveals that CO2 formation increases ...

Risk assessment of the production of seaweed in the Netherlands; food safety and nature

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Seaweed is seen as an important source of alternative proteins for a sustainable food system and food security. The cultivation of seaweed is therefore encouraged by the European Union (EU) and also by the Dutch government.In the Netherlands, seaweed is farmed on small scale in the Southwest Delta, the Wadden Sea and the North Sea. Despite the

Investigation of tribological properties of lithium grease with SiO2 nanoparticles [PDF]

IOP Conference Series: Materials Science and Engineering, 2019
Abstract The aim of the work was to investigate the effect of the SiO2 nanoparticles concentration in the lithium grease and of contact pressure on the spinning friction coefficient in the contact zone between a steel plate and a ball. The invvestigations were carried out using the a tribotester for the spinning friction torque in the ...

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...
