Imparting Biodegradability to Highly‐Efficient Upconversion Nanoparticles via Facet‐Selective Zirconium Doping

open access: yesSmall, EarlyView.
A simple incorporation of Zr imparts biodegradability to inherently inert rare‐earth‐based upconversion nanoparticles without compromising optical performance. Surface energy modulation of LiREF4 facets by a binary‐surfactant system enables Zr incorporation during hot‐injection synthesis.

Compostable and Recyclable Baroplastic Triblock Copolymers Enable Low‐Energy Polymer Processing

open access: yesSmall, EarlyView.
Baroplastic Poly(L‐lactide)‐block‐poly(ethylene glycol)‐block‐poly(L‐lactide) triblock copolymers enable ambient‐temperature processing under moderate pressure, reducing energy demand while preserving polymer integrity. The materials show rapid industrial compostability, effective chemical and physical recyclability, and compatibility with heat ...

Finding Minimum‐Cost Explanations for Predictions Made by Tree Ensembles

open access: yesSoftware: Practice and Experience, EarlyView.
ABSTRACT The ability to reliably explain why a machine learning model arrives at a particular prediction is crucial when used as decision support by human operators of critical systems. The provided explanations must be provably correct, and preferably without redundant information, called minimal explanations.

Monitoring of historical structural materials with computed tomography

open access: yesStructural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Microbial Community Dynamics in Marine Water: Influence of Hydrocarbon Type and Exposure Time

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Marine environments are frequently impacted by petroleum‐derived hydrocarbons, which pose ecological risks because of their toxic, mutagenic, and carcinogenic potential. Microorganisms play a crucial role in hydrocarbon degradation, and understanding the influence of time and hydrocarbon type on microbial dynamics helps improve bioremediation ...
