Carbon monoxide impurities in hydrogen detected with resonant photoacoustic cell using a mid-IR laser source

Photoacoustics
We report on a photoacoustic sensor system based on a differential photoacoustic cell to detect the concentration of CO impurities in hydrogen. A DFB-QCL laser with a central wavelength of 4.61 µm was employed as an exciting source with an optical power ...

Paying for Privilege: How Political Contributions Undermine Environmental Sustainability—And How Executive Contracting Can Restore Balance

Business Strategy and the Environment, EarlyView.
ABSTRACT We are interested in investigating whether firms use political donations as a license to neglect environmental sustainability. We further deepen the examination by exploring the role of executive contracting. Drawing on a wide range of data between 2002 and 2021 and a global sample, our findings confirm that firms use political contributions ...

Intravascular Ultrasound in Chronic Limb‐Threatening Ischemia Endovascular Revascularization: A Multidisciplinary Survey of Clinical Practices and Operator Perceptions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular ultrasound (IVUS) may be beneficial for guiding endovascular revascularization in patients with chronic limb‐threatening ischemia (CLTI); however, its use remains limited. Methods We surveyed interventional radiologists, vascular surgeons, and interventional cardiologists in the United States, Canada, and the United ...

Linking Decisional Support to Career Self‐Efficacy and Outcome Expectations via Learning Experiences in Turkish Undergraduates

The Career Development Quarterly, EarlyView.
ABSTRACT Drawing on the social cognitive model of career self‐management, the present study examines the relationships among decisional support, learning experiences (i.e., mastery experiences, verbal persuasion, vicarious learning, positive emotions, and negative emotions), self‐efficacy, and outcome expectations in relation to career exploration and ...

1D U-Net Enhanced QEPAS Sensor for Trace Water Vapor Detection

Optics
We report a deep learning-assisted quartz-enhanced photoacoustic spectroscopy (QEPAS) sensor for trace water vapor detection in air. A 1392 nm butterfly-packaged DFB laser is wavelength-modulated at f0/2, and the QEPAS signal is retrieved by second ...

Dinuclear Group 4 Metallocene Catalysts of the Type [(Cp2M)2(μ‐Me)(μ‐C2R)]: Structure‐Activity Relationships in Ethylene Polymerization

Chemistry – A European Journal, EarlyView.
Homo‐ and heterodinuclear group 4 metallocene complexes of the type [(Cp2M)2(μ‐Me)(μ‐C2R)] (M = Ti, Zr) are active catalysts for the polymerization of ethylene in the presence of aluminium‐free activators. The catalytically active species are proposed to have dinuclear character and depending on the type of activator, unique reactivity was observed ...

Mechanochemical Amidation Mediated by 1,1’‐Oxalyldiimidazole for the Synthesis of Agrochemicals

Chemistry – A European Journal, EarlyView.
Mechanochemical amidation using 1,1'‐oxalyldiimidazole (ODI) overcomes limitations of 1,1’‐carbonyl diimidazole (CDI) as coupling agent by enabling the efficient mechanochemical synthesis of three marketed agrochemicals from deactivated carboxylic acids.

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Energy Landscapes in Chemical Reactions and Transport

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Does Next Generation Sequencing (NGS)‐Based CYP2D6 Sequencing Improve Genotype–Phenotype Concordance in Tamoxifen‐Treated Patients?

Clinical Pharmacology &Therapeutics, EarlyView.
CYP2D6 metabolizes about 20% of commonly used drugs, including tamoxifen, a major hormone therapy for breast cancer. Although the relationship between tamoxifen pharmacokinetics and CYP2D6 genotype has been demonstrated, residual variability in drug exposure remains unexplained.
