Effects of Hold Time on the Elevated Temperature Fatigue Crack Growth Behavior of Alloy 247LC‐DS

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Creep–fatigue crack growth (CFCG) experiments were performed at 850°C and 950°C on nominally 12.70‐mm‐thick compact‐type specimens of alloy 247LC‐DS, a Ni‐base superalloy. The loading cycles consisted of trapezoidal waveforms with hold times of 2 and 20 min at the maximum force.

Effect of Matrix Properties on Quasi‐Static and Fatigue Properties of Thermosetting Polyurethane and Its GFRP Composites

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In this study, the influence of resin cross‐link density on thermomechanical properties and fatigue behavior of polyurethane resins and glass fiber‐reinforced polyurethane (PUR‐GFRP) composites was investigated. This material is a candidate for renewable energy applications like rotor blades in wind turbines.

Mergers and Acquisitions as Navigators of Climate Policy Shocks: Evidence from the NOx Budget Trading Program

Financial Management, EarlyView.
ABSTRACT We examine how mergers and acquisitions (M&As) enable firms to adapt to climate policy shocks. Exploiting the adoption of the Nitrogen Oxides (NOx) Budget Trading Program (NBP) across US states as an exogenous shock, we find that firms with NOx‐emitting plants subject to the NBP are more likely to engage in M&As, particularly through vertical ...

A Call to Industry: Unearthing Synergies in Subsurface Storage Technologies

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Subsurface storage technologies (SSTs), including geological CO2 sequestration, underground hydrogen storage, compressed‑air energy storage and thermal energy storage, are emerging as a scalable route for industry to achieve the terawatt‑hour storage flexibility and permanent carbon removal that evolving energy systems demand.

Psychological responses to interval and continuous exercise in people living with HIV: A single‐blind, counterbalanced, crossover study

HIV Medicine, EarlyView.
Abstract Aim This study compared acute psychological responses to a single session of low‐volume high‐intensity interval exercise (HIIE‐LV), high‐volume high‐intensity interval exercise (HIIE‐HV), and moderate‐intensity continuous exercise (MICE) in people living with HIV, and healthy controls using a randomized, counterbalanced crossover design ...
