Creep crack growth behavior of P91 steel weldments
Thermal Science, 2019 The steels operating at elevated temperatures are well known to be exposed to premature failure due to cracking caused by constant thermal stress, i.e. secondary creep process. Therefore, creep crack growth (CCG) tests were carried out on compact tension (CT) specimens machined from P91 weld joint at 600°C to determine its behaviour in realistic ...

Geometry Controls Confined Water Dynamics in Lipidic Mesophases
Angewandte Chemie, Volume 138, Issue 7, 9 February 2026.An archaeal‐inspired lipidic mesophase allows precise control of interfacial curvature and water‐channel connectivity. Combining structural, thermodynamic, and ultrafast spectroscopies, we reveal that curvature governs the structure and reorientation dynamics of confined water, establishing a molecular‐level link between topology and dynamics in soft ...

British Journal of Educational Psychology, EarlyView.Abstract Background As AI‐enabled social robots become more common in schools, children may form strong emotional bonds with them despite robots not being caregivers and lacking the capacities for “true” attachment. Given limited understanding of potential risks and safeguards, professional perspectives are needed to inform responsible design and ...

Applicability of the induction bending process to the P91 pipe of the PGSFR
Nuclear Engineering and Technology, 2021 The application of induction bending processes to industrial pipe production is increasing. The induction bending process has the effect of reducing the number of inspections and preventing leaks by reducing the weld of the pipe.

Lived Experiences of Pregnancy Loss at Work: Realizing Meaningful Supports
Gender, Work &Organization, EarlyView.ABSTRACT There is increased focus on pregnancy loss at work over recent years, with many countries introducing or exploring the introduction of statutory leave for pregnancies that end pre‐“viability.” Individual organizations are also introducing their own pregnancy loss policies.
