Crystal Structure and Eu2+ Luminescence of the Lithium Alkaline‐Earth Silicate Fluoride LiBa2SiO4F

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
With Li2BaSiO4F, a new lithium alkaline‐earth silicate fluoride could be synthesized via high‐temperature solid‐state reaction. Crystal structure and luminescence properties upon Eu2+ activation were investigated. A high‐temperature solid‐state synthesis in weld‐shut tantalum ampoules yielded a new alkaline‐earth silicate fluoride, LiBa2SiO4F.

Artificial Neural Network Surrogate Modelling for Predicting and Optimising CO2 Conversion to Methanol Under Uncertainty

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This study introduces a data‐driven surrogate modelling framework that combines an artificial neural network (ANN) with particle swarm optimisation (PSO) and a genetic algorithm (GA) to optimise methanol production under uncertain conditions.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Uncovering hidden bias in neutron diffraction residual strain measurements

Journal of Applied Crystallography, EarlyView.
This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

Journal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,
