Photoluminescence Enhancement in Erbium Nanoparticles via Controlled Phase Transformation

Small, EarlyView.
Er‐NPs synthesized by PLAL were thermally treated from 200°C to 1000°C. Annealing at 600°C produced a full transition to the cubic Er2O3 phase and removed non‐radiative surface species. This led to a fivefold increase in PL. The results show how oxidation and phase purity control the optical performance of Er‐NPs.

Laying the Foundation for Digital Material Design of Porous Transport Electrodes for PEM Water Electrolysis With Multiscale Tomography

Small, EarlyView.
This paper presents the first multiscale identical location tomography of a porous transport electrode for PEM water electrolysis. Different tomography and modeling approaches determine the relevant structural properties ranging from micrometer‐thick fibers to nanometer‐thin binder films covering the catalyst particles.

Automated Identification of Thermal Transitions in Conjugated Material Thin Films Using In Situ Optical Spectroscopy

Small Methods, EarlyView.
This study demonstrates the effectiveness of in situ UV−vis coupled with automated data analysis, namely, ATLAS, for fast and reliable identification of multiple thermal transition in conjugated polymer thin films. This ATLAS method will significantly accelerate the understanding of the phase behavior of D‐A polymers with important implications for ...

Recent advances of non‐invasive sensors for smart wearable respiratory monitoring

VIEW, EarlyView.
Respiration contains rich physiological and pathological information, making it one of the most fundamental and continuous vital signs. Respiration monitoring is a non‐invasive and simple, but incredibly powerful, tool for assessing health, managing disease, and tracking fitness.

Evolutionary Dynamic Multiobjective Optimisation Assisted by Inverse Regression Tree Predictor

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Dynamic multiobjective optimisation problems (DMOPs) are optimisation problems with multiple conflicting objectives that can change over time. Most dynamic multiobjective optimisation evolutionary algorithms (DMOEAs) attempt to estimate Pareto‐optimal sets (PS) directly in the decision space.

Spin‐contrast‐variation small‐angle neutron scattering study of fully and partially swollen silica‐filled rubber

Journal of Applied Crystallography, EarlyView.
We have elucidated the polymer adsorption layer structure in filler–rubber systems by conducting spin‐contrast‐variation small‐angle neutron scattering on partially and fully swollen filler–rubber samples with and without a silane coupling agent.We have elucidated the polymer adsorption layer structure in filler–rubber systems by conducting spin ...

Size variation of an herbivorous insect affects host plant damage: Mechanisms behind the effect

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific trait variation can strengthen or weaken species interactions in ecological communities. A mechanistic understanding of how intraspecific variation affects species interactions will help identify general rules about when intraspecific variation strengthens
