Perlite incorporation for sedimentation reduction and improved properties of high-density geopolymer cement for oil well cementing

open access: yesScientific Reports
Portland cement (PC) is known for its environmental and technical concerns and massive energy consumption during manufacturing. Geopolymer cement is a promising technology to totally replace the use of PC in the oil and gas industry. Although geopolymers

Elevated UV‐B alters anti‐herbivore plant defence allocation, while silicon supplementation maintains resistance

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2982-3000, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The impacts of elevated surface ultraviolet‐B (UV‐B) on ecological processes, such as anti‐herbivore defence in plants, remain poorly understood. Many cereal crops depend on accumulating silicon (Si) in their tissues to resist insect herbivory.

An Exploration of Mechanochemical Activation on Various Potential Supplementary Cementitious Materials

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT The use of supplementary cementitious materials (SCMs) is a major way to reduce the carbon footprint of concrete. Mechanochemical activation (MCA) can be used to activate inert materials that can then be used as SCMs. In this study, the effect of MCA using a planetary ball mill was investigated for 16 materials, ranging from natural occurring ...

Effect of various additives on the hydration of perlite-Gypsum plaster and perlite Portland cement pastes

open access: yes, 1997
Perlite is a volcanic glass which forms a light-weight cellular aggregate when ground and heated to about 1000 degrees C. It is used in the production of light-weight masonry blocks and concrete in the building industry as well as in insulation, fire ...

Comparative efficacy and studies of mode of action of minerals from diatoms against three species of filth flies

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 3, Page 478-488, September 2026.
Mortality for diatomaceous earth was observed as early as 2 h after exposure with 50% and 90% mortality at 3.5 and 4.6 h (LT50 and LT90, respectively) for Musca domestica. The LT50 and LT90 increased when the size of the fly species increased (M. domestica to Cochliomyia macellaria to Sarcophaga bullata) and increased for all three from 50 to 70 ...

Water Availability and Hydraulic Strategies Control Leaf Thermoregulation and Damage During Heat Stress and Recovery in Temperate Tree Species

open access: yesPlant, Cell &Environment, Volume 49, Issue 9, Page 6296-6310, September 2026.
ABSTRACT Heatwaves are intensifying worldwide, often coinciding with high vapour pressure deficit (VPD) and soil drought. Yet, how temperate tree species tolerate these combined stresses remains elusive. Using single‐tree gas‐exchange chambers, we examined the response of leaf gas exchange and thermoregulation of three broadleaved tree species to a ...

Nitric Oxide and Phytohormone Crosstalk Mediates Soybean Growth and Defence Against Aphis glycines

open access: yesPhysiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Aphid infestation, particularly by Aphis glycines, poses a major threat to soybean (Glycine max) production, necessitating sustainable defence strategies. This study evaluated the role of nitric oxide (NO) donor S‐nitrosocysteine (CySNO) in enhancing soybean resistance to aphids through hormonal crosstalk.
