On the hygrothermal properties of sandcrete blocks produced with sawdust as partial replacement of sand

Journal of the Mechanical Behavior of Materials, 2021
In Nigeria, sawdust is continuously generated in large quantities as waste but majorly under-utilised, a situation which causes serious environmental problems and health hazards when managed improperly.

Bacterial healing of cracks in metakaolin‐based geopolymer concrete exposed to high temperatures

Structural Concrete, EarlyView.
Abstract This study examined the bacterial healing of metakaolin‐based geopolymer concrete modified with colemanite (K) and red mud (RM) exposed to high temperatures. The metakaolin‐based geopolymer concrete samples modified with 4% K and 6% RM were prepared.

Influence of Varying Curing Temperatures on the Mechanical and Durability-Related Performance of Multi-SCM Blended High-Strength Self-Compacting Concrete

Buildings
Self-compacting concrete (SCC) offers major advantages in construction; however, its high paste content makes its performance highly sensitive to curing temperature and binder composition.

The 5T Paradox of Triclosan: From Toiletries to Toxic Trash, a Growing Threat to Humanity

Environmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) persists as a contaminant of concern in the Anthropocene, despite regulatory actions. Environmental dissemination continues through wastewater effluents, biosolid application, and improper disposal practices. This narrative review synthesizes current evidence regarding triclosan's environmental fate, transformation pathways ...

A guide to the ecological limitations of phage therapy of bacterial biofilms: Is what's best for the phage best for the physician?

The FEBS Journal, EarlyView.
Bacteriophages—viruses that kill bacteria—are promising weapons against bacterial biofilms: sessile communities notoriously resistant to antibiotics. Yet phages evolved not so much to eradicate bacteria as to obtain new bacteria to infect. That goal, however, may conflict with the physician's objective of complete bacterial clearance.

Airborne Immunity: A Bacterial Volatile Primes Plant Defenses by Unlocking a Phytoalexin Biosynthetic Checkpoint

Plant, Cell &Environment, EarlyView.
ABSTRACT Microbial volatile organic compounds (mVOCs) enable plants to perceive microbial activity prior to physical contact, yet the contribution of individual bacterial volatiles to immune signalling and disease resistance remains incompletely understood.

Efficacy of Zeolite and Kaolin in the Control of Cacopsylla pyri (L.) (Hemiptera: Psyllidae) and Compatibility With Its Natural Antagonist Anthocoris nemoralis (Fabricius) (Hemiptera: Anthocoridae)

Journal of Applied Entomology, Volume 150, Issue 8, Page 1080-1087, September 2026.
ABSTRACT The pear psyllid Cacopsylla pyri is a major pest of European pear orchards, responsible for significant yield losses. Its management is increasingly challenged by restrictions on synthetic active ingredients, resistance development, and the shift towards sustainable production systems.
