Modelling Particulate Matter (PM10) Variations During Transboundary Haze Events Using a Modified Quantile Regression Approach

Analytical Science Advances, Volume 6, Issue 2, December 2025.
ABSTRACT Severe haze episodes in Southeast Asia, largely attributed to transboundary pollution from neighbouring countries, have led to substantial environmental degradation and adverse health effects. This study presents the development of a novel air quality forecasting model specifically developed to predict particulate matter with a diameter of ...

Gels for CO2 geo‐storage and conformance control: A systemic review of behavior and performance

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 612-637, December 2025.
This review provides a systemic evaluation of potential sealants used in CO2 subsurface storage practices. Critical analyses of how external factors like CO2, pH, brine salinity and hardness, rock mineralogy, pressure, temperature, and injectivity could affect the performance of different sealants are provided. Abstract Carbon capture and storage (CCS)

Reuse of iron ore tailings in the production of geopolymer mortars

REM: International Engineering Journal
A great variety of silica and alumina-rich materials have been investigated in the production of alkaline activated binders (or geopolymers) with low environment impact, e.g. low CO2 emissions. Geopolymer mortars and concretes may be more environmentally

Elevated Temperature Behavior of Bagasse and Human Hair Fiber‐Reinforced Fly Ash Geopolymer Composites

Engineering Reports, Volume 7, Issue 12, December 2025.
This study demonstrates that human hair fiber‐reinforced fly ash geopolymer composites outperform bagasse‐based counterparts at elevated temperatures. They show higher mechanical strength, less thermal weight loss, and stronger fiber–matrix bonding, making them promising sustainable reinforcements for thermally demanding applications.
