Advanced Terahertz Sensing of Liquid Petrochemicals: Pentagonal‐Core Photonic Crystal Fiber Design and Performance

Advanced Photonics Research, Volume 7, Issue 7, July 2026.
A hybrid‐structured pentagonal‐core photonic crystal fiber sensor operating in the terahertz regime is proposed for fuel adulteration detection. Numerical analysis using the finite element method in COMSOL shows optimal performance at 2 THz, achieving high relative sensitivity (up to 98.20%) with ultralow confinement loss (~10−¹³ dB/m). The design also

Civilian Occupational Exposure to Vapors, Gas, Dust, or Fumes and Respiratory Health Among United States Military Veterans

American Journal of Industrial Medicine, Volume 69, Issue 7, Page 503-511, July 2026.
ABSTRACT Background We investigated associations of self‐reported and job exposure matrix (JEM) assigned civilian occupational exposure to vapors, gas, dust, or fumes (VGDF) with respiratory symptoms among previously deployed US Veterans. Methods An interviewer‐administered questionnaire ascertained self‐reported civilian occupational VGDF exposure.

Respirable Dust Exposure in Western Australian Mining: Trends, Variability, and Implications for Occupational Health

American Journal of Industrial Medicine, Volume 69, Issue 7, Page 540-547, July 2026.
ABSTRACT Background Mining workers are exposed to a range of respiratory hazards, including respirable dust. While exposure to respirable crystalline silica in the mining industry has been found to be common, less is known about trends in measured levels of exposure to respirable dust overall.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1683-1707, July/August 2026.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Magnetic lipase B from Candida antarctica (CALB) biocatalyst for integrated valorization of tilapia by‐products and biodiesel biorefining

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1835-1860, July/August 2026.
Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...

Simulating competition in the US bioeconomy to produce hard‐to‐electrify transportation fuels using limited biomass resources

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1895-1910, July/August 2026.
Abstract This study presents a novel bioeconomy optimization framework, BiOpt, designed to address critical questions regarding the strategic use of limited US biomass resources for biofuel production. By integrating detailed techno‐economic analyses, life cycle assessments, and resource assessment data, BiOpt optimizes resource distributions across ...
