Polymer Stress‐Tensor Calculation for a Laminar Submerged Viscoelastic Jet Flow Using Different Constitutive Models

International Journal for Numerical Methods in Fluids, EarlyView.
This study presents an efficient method to compute polymer stress‐tensor components in viscoelastic laminar jet flows using models such as Oldroyd‐B, Giesekus, PTT, and FENE. By assuming a stationary and parallel flow, the methodology significantly reduces computational cost.

Enhancing the Sensitivity of Colorimetric Aptasensor Through Cd2+‐Thymine Interactions in ssDNA Loops for Food Contaminant Detection

Food Safety and Health, EarlyView.
This picture illustrates a novel aptamer‐based colorimetric assay, which demonstrates that high sensitivity, selectivity, and reliability for the rapid detection of cadmium ions (Cd2+) in water. Molecular dynamics (MD) simulations have revealed that the complexes are more stable, with Cd2+ binding more tightly to the thymine (T) within the aptamer loop.

Downdraft Devices for Negative Emissions—Quantification Study and Environmental Implication

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Methane (CH4) is a potent greenhouse gas with a global warming potential far exceeding that of CO2 over short time horizons. Its removal from the atmosphere remains challenging due to its low ambient concentration and chemical stability. This study explores downdraft energy towers (DETs) as an innovative CH4 mitigation technology that enhances

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, EarlyView.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Sustainability Performance and Corporate Risk: Evidence From the Tourism Industry

International Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the impact of sustainability performance (Refinitiv Environmental, Social, and Governance [ESG] scores) on corporate risk (CR). We apply stakeholder theory and the resource‐based view to an international sample of 247 tourism firms from 2002 to 2018.
