High temperature fracture behavior and damage evolution of recycled aggregate concrete produced from metakaolin modified parent concrete

open access: yesStructural Concrete, EarlyView.
Abstract The increasing use of recycled aggregate concrete (RAC) offers significant environmental benefits by reducing construction and demolition waste; however, its fracture performance and damage evolution under elevated temperatures remain insufficiently understood, particularly when recycled aggregates are derived from metakaolin modified parent ...

Influence of Octaglycidyl‐POSS on Processing Behavior, Gelation Kinetics, and Thermomechanical Properties of a DGEBA/Polyamidoamine Epoxy System

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
The rigid, octafunctional Si8O12 cage of OG‐POSS incorporates into the DGEBA/polyamidoamine network as a multifunctional junction, raising the glass transition temperature (Tg) by up to 19°C and the apparent crosslink density non‐monotonically by 47%‐71% at 1.5, 3.0, and 5.0 phr loading.

Resistivity and Tensile Strength of Al–Mg–Si Alloy Wire Conductors

open access: yesHigh Voltage, EarlyView.
ABSTRACT Aluminium alloy is potentially used for power transmission lines due to its light weight and high strength. The aluminium alloy wire conductors with different Mg and Si contents were studied through electrical resistivity and mechanical properties.

Polynomial‐shaped electrodes for adaptive X‐ray optics

open access: yesJournal of Synchrotron Radiation, EarlyView.
A shaped electrode design for lithium niobate adaptive X‐ray mirrors connects actuator degrees of freedom to specific polynomial orders, enabling general shape control and the correction of defocus, coma and fourth‐order aberrations with a limited number of inputs.For adaptive mirrors on X‐ray beamlines and optical systems, we describe a strategy for ...

Optimizing diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide concentration and post‐curing time to balance mechanical properties and color stability in a three‐dimensional‐printed restorative resin

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Three‐dimensional (3D) printing is widely used in dental restorations; however, optimization of photoinitiator concentration and post‐curing protocols remains critical to achieve a balance between mechanical and esthetic performance. This study evaluated the combined effect of diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide (TPO) concentration
