Artificial-weathering test requirements for fire-retardant-treated wood to reproduce optimal chemical retention and moisture conditions

Journal of Wood Science
Despite the increasing outdoor use of fire-retardant-treated wood, methods for predicting its service life remain poorly established. With the aim of establishing a method to predict chemical losses from fire-retardant-treated (FRT) wood caused by humid ...

Mechanistic insights across curing regimes for enzymatic and biopolymer‐optimized reinforcement in rock masses

Deep Underground Science and Engineering, EarlyView.
This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...

EU Policy‐Making in the Digital Age: Major Trends and Insights From Public Policy Research

European Policy Analysis, EarlyView.
ABSTRACT Has digitalization changed policy‐making dynamics at the European Union (EU) level? To investigate this issue, this article presents a scoping review of the literature on EU digital policy‐making. While much scholarship adopts a ‘Governance’ approach, two conceptually rich strands emerge: critical approaches, and digital sovereignty.
