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

Structural 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 ...

Integrated Alpha–Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...

What can be done virtually? A modified Delphi study offering guidance on virtual companion animal physical examinations

Veterinary Record, EarlyView.
Abstract Background The inability to adopt a hands‐on approach can be viewed as a limitation to provide veterinary care virtually. The objective of this study was to establish guidance to support the remote delivery of a companion animal physical examination by video. Methods A modified approach to the Delphi method was followed.

Magnetic Structure of the High‐TN Antiferromagnet La0.5Sr3.5Fe3O7.5F2.6: A Temperature‐Dependent Mößbauer Spectroscopy and Neutron Diffraction Study

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
La0.5Sr3.5Fe3O7.5F2.6, a rare n = 3 Ruddlesden–Popper oxyfluoride, exhibits robust antiferromagnetism across a wide temperature range from 1.7 to 470 K. Temperature‐dependent neutron diffraction reveals an orthorhombic nuclear and a monoclinic magnetic structure, while Mößbauer spectroscopy shows persistent short‐range magnetic order up to 525 K.
