Electromagnetic dissociation of relativistic $^8$B nuclei in nuclear track emulsion

, 2009
Experimental data on fragmentation channels in peripheral interactions of $^8$B nuclei in nuclear track emulsions are presented. A detailed analysis made it possible to justify selections of events of the electromagnetic-dissociation process $^8$B $\to^7$

Influence of Battery Electrode Chemistry on Electrolyte Decomposition

Advanced Materials Interfaces, EarlyView.
The formation of a stable solid‐electrolyte interphase (SEI) is crucial for rechargeable batteries. This study reveals how carbonaceous (glassy carbon), semiconducting (silicon), and metallic (copper) electrode materials influence SEI nucleation and electrolyte decomposition.

Enhanced Performance 3‐D Printed PLA Parts through a Photo‐Initiator Mediated UV‐Curing

Advanced Materials Technologies, EarlyView.
This solvent‐free method enhances 3‐D printed PLA parts by incorporating photo‐initiators during fabrication, followed by up to 3 min UV treatment. This process improves PLA's mechanical properties, including a 64% increase in tensile strength, while addressing weak interlayer bonding and outdoor sensitivity.

State and parameter estimation using Monte Carlo evaluation of path integrals

, 2009
Transferring information from observations of a dynamical system to estimate the fixed parameters and unobserved states of a system model can be formulated as the evaluation of a discrete time path integral in model state space. The observations serve as

The Importance of Metal Ion Impurity Bands in the Photoluminescence of Halide Double Perovskites

Advanced Optical Materials, EarlyView.
Many publications have associated emission spectral features of double perovskite halides in the region at 460–470 nm with “pristine” materials. This leads to not only false observations but also incorrect conclusions concerning the transformation of dark into bright excitons or boosting self‐trapped exciton emission.
