Beyond hydrogen: Process design of a biogas steam reformer for Fischer–Tropsch synthesis

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
The effect of pressure and steam to carbon ratio on carbon conversion. Abstract We present an analysis of a pilot‐scale multi‐tubular biogas steam reforming reactor, part of a sustainable aviation fuel (SAF) development project in Brazil. The novelty of this work is the application of a new, validated power law kinetic model, specifically developed for

Exploring Sustainability Reporting Practices in an Emerging Market: Insights From Corporate Governance and Disclosure Tone

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The study examines how narrative disclosure tones (NDTs) and corporate governance mechanisms (CGMs) affect sustainability reporting practices (SRP) in an emerging economy. Data from 125 non‐financial firms in Pakistan, spanning 2011–2022, are utilized. SRP is measured using both GRI and the novel IFRS S1 standards‐based indices. Three NDTs are

Engineering CEOs, Sustainability Performance, and Greenwashing: Evidence From Australian Listed Firms

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines how engineering trained chief executive officers (CEOs) determine firms' sustainability performance and greenwashing behavior in Australian listed firms from 2016 to 2024. Drawing on Upper Echelons theory and Imprint theory, we argue that engineering cognition influences environmental strategy by providing conservative ...

Elimination Profile of Deflazacort and Metabolites in Urine and Plasma Following Oral Administration: Relevance to Sports Drug Testing

open access: yesDrug Testing and Analysis, EarlyView.
Results confirm that the MRL of 30 ng/mL for 21‐desacetyl‐deflazacort together with a 3‐day washout period is an appropriated strategy to detect oral deflazacort administration in sport competition. ABSTRACT Deflazacort (DEF) is a glucocorticoid prohibited in sports competitions when orally administered.

The interaction of solar radiation modification with Earth system tipping elements [PDF]

open access: yesEarth System Dynamics
The avoidance of hitting tipping points has been invoked as a significant benefit of solar radiation modification (SRM) techniques; however, the physical science underpinning this has thus far not been comprehensively assessed.

Detection of Testosterone Esters in Urine: Evidence of Trace‐Level Detectability in Doping Control Samples

open access: yesDrug Testing and Analysis, EarlyView.
An ultrasensitive LC‐MS/MS method for detecting testosterone esters (T‐esters) in urine at sub–pg/mL levels is presented. This approach, employing Girard P derivatization, provides the first evidence of T‐esters' trace‐level detectability in human urine.

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.
