Fast and Sensitive Measurement of Off‐Flavors in Recirculating Aquaculture Systems

Rapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Geosmin and 2‐methylisoborneol (2‐MIB) are odor‐active compounds responsible for earthy off‐flavors in fish, creating significant quality concerns in recirculating aquaculture systems (RAS). Their extremely low odor thresholds make rapid and highly sensitive detection essential for maintaining product quality and consumer acceptance ...

SORPTIVITY AND CHLORIDE PENETRABILITY EVALUATION OF CONCRETE INCORPORATING FLY ASH AND SILICA FUME

Journal of Civil Engineering
Diffusion is one of the the main mechanisms of fluid ingress into the concrete. However, in partially saturated concrete, the fluid will mainly be absorbed by the capillary suction mechanism, which associates with the sorptivity properties of the ...

Analysis of Arsenic, Cadmium, Chromium, and Lead Levels: Interplay of Climate, Soil, and Human Factors in Urban Gardens

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract Understanding the spatial distribution of heavy metals in urban gardens is essential for mitigating contamination risks and supporting safe urban agriculture. This study examines factors influencing heavy metal concentrations in garden soil across San Antonio, Dallas, and Houston.

Texture and Neonicotinoid Exposure Shape Bacterial Assemblages and Functions in Agricultural Soils: Responses Over Prolonged Exposure

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
In a 28‐day soil microcosm experiment, bacterial communities responded differently to imidacloprid across contrasting soil textures, with soil‐dependent changes in community structure, interaction networks and functional pathways, while overall diversity remained largely stable.

Development of a universal microinfiltrometer to estimate extent and persistence of soil water repellency as a function of capillary pressure and interface chemical composition

Journal of Hydrology and Hydromechanics, 2020
Microinfiltrometers to assess soil water repellency (SWR) are limited to small tension ranges and have different technical setups, hindering a comparison between results from different laboratories.

Ettringite Seeds for Strength Enhancement: Novel Synthesis via One‐Step Co‐Precipitation

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Reduced early strength can be a barrier to the adoption of cements blended with high levels of limestone. Chemical admixtures based on nucleation seeding are emerging as a potential solution. Herein, while synthesis of C‐S‐H‐based seeds has been thoroughly investigated in the literature, there are limited synthesis protocols available on other

Substantial Accumulation of Chemically Oxidizable Organic Carbon in Continental Margin Sediments

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The balance between organic carbon (OC) sequestration and oxidation regulates the oceanic carbon cycle, and OC reactivity determines its susceptibility to remineralization or long‐term burial. However, the stability of sedimentary OC on continental margins remains poorly understood.

Effect of Low-Grade Calcined Clay on the Durability Performance of Blended Cement Mortar

Buildings
Recent studies have shown the viability of low-grade calcined clays as a partial substitute for cement in construction applications. However, there is limited information about the performance of low-grade calcined clay in withstanding chloride-rich ...
