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 ...

Achieving sustainable and durable concrete using high‐volume SiO2: Engineering properties, environmental and economic benefits

open access: yesStructural Concrete, EarlyView.
Abstract This study explores the potential of high‐volume amorphous silica (SiO2) replacement for ordinary Portland cement (OPC) in concrete to reduce carbon emissions. Amorphous SiO2, such as silica fume (SF) and CO2 mineralization‐produced Si‐rich gel, offers superior properties to concrete but is under‐researched for its use in concrete with high ...

Polymorphism and NIR Photoluminescence of Anhydrous Ytterbium(III) Acetate: Reversible Transformations of Three Polar Structures in the Temperature Range 100–593 K

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Crystallographic variety, reversible transitions, and NIR emission of anhydrous Yb(OAc)3: identification of a new γ‐phase results in altogether three modifications all crystallizing in polar space groups related by reversible solid–solid phase transitions.

Sr2[CN2][NH] – A Carbodiimide Imide

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The mixed anion compound Sr2[CN2][NH] contains carbodiimide anions alongside imide anions and shares structural similarities with the respective quasi‐binary compounds. The novel mixed anionic compound Sr2[CN2][NH] crystallizes as colorless transparent platelets in the orthorhombic space group Pnma.

Systematic investigation of the diffraction efficiency of sub‐15 nm resolution soft X‐ray zone plates via simulation and measurement

open access: yesJournal of Synchrotron Radiation, EarlyView.
This study presents systematic measurements and rigorous coupled‐wave analysis of relative and absolute diffraction efficiencies for sub‐15 nm soft X‐ray Fresnel zone plates. By decoupling intrinsic optical performance from practical beamline transmission losses, this work establishes a highly reliable metrology framework to support the development of ...
