Study on the Attack of Concrete by External Sulfate under Electric Fields

Coatings
The research on and application of electric fields to promote the rapid infiltration of ions into cement concrete have been widely explored. Still, there are few studies on the migration of sulfate ions using electric fields. In this paper, a new test method is designed using the principle of electric fields, that is, to accelerate the attack of ...

Sex as a biological variable in nonclinical studies: Bridging scientific rigor, animal welfare, and regulatory expectations

Animal Models and Experimental Medicine, EarlyView.
Sex as a biological variable (SABV) is a critical determinant of pharmacokinetics, pharmacodynamics, and toxicity in nonclinical studies. This review highlights how inappropriate neglect of sex differences compromises animal welfare, scientific reproducibility, and regulatory compliance.

Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Effect of Temperature and Atmosphere on Agglomeration of Bed Particles in a Bubbling Fluidised Bed Burning Na‐Enriched Coal

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Agglomeration of bed materials during circulating fluidised bed (CFB) combustion or gasification of high‐alkali fuel is a practical challenge in industrial practice. This work investigates experimentally the effect of temperatures (700°C–900°C) and atmosphere (air equivalence ratios 1.61–0.53) on agglomeration in a lab‐scale bubbling fluidised
