Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

open access: yesDeep Underground Science and Engineering, EarlyView.
In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Terpenes and Terpenoids: How can we use them?

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The transition from petroleum‐based to renewable bio‐based chemicals has led to increased interest in terpenes and terpenoids. This overview highlights their chemistry, focusing on their reactivity and applications in polymerizations, total syntheses, pharmaceuticals, and bio‐based chemical conversions; promoting sustainable and green chemical ...

Systematic Investigation of the Residence Time Distribution in a Twin‐Screw Extruder for the Continuous Mixing Process of Electrode Slurry in the Battery Cell Production

open access: yesEnergy Technology, EarlyView.
The residence time distribution in the continuous mixing process for battery raw material is systematically investigated. Suitable tracers are identified, with NaCl for the twin‐screw extruder and sodium bicarbonate for powder dosing. Key parameters are varied, showing that mass flow has the strongest influence, while solid content also plays a ...
