Structure–Activity Relationships in Methyl‐Driven Overhauser Effect DNP

Chemistry – A European Journal, EarlyView.
Dynamic nuclear polarization (DNP) was investigated in a wide array of methyl‐containing Blatter radicals to identify design principles for the synthesis of an Overhauser DNP polarizing agent. Fourteen different radicals were synthesized, which revealed that only radicals possessing sterically unhindered methyl groups in sites of high spin density were

Designing Governance for ESG: Incentive and Oversight Complementarities in Corporate Sustainability Performance

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates how internal governance design supports credible ESG performance by distinguishing between Incentive and Oversight Architectures. Using 13,993 firm‐year observations of US nonfinancial firms from 2018 to 2024, we estimate fixed effects and two‐step system GMM models.

An Adaptive Series-Dynamic-Resistor-Based Protection Scheme for Brushless Doubly- Fed Induction Generator Under Asymmetrical Fault Conditions

IEEE Access
Low-voltage ride-through (LVRT) is one of the most important criteria for integrating wind energy into the power grid. Based on grid connection codes, wind generators must remain connected during fault conditions.

How Fitness Center Environments Influence Eating Disorder Recovery: Learning From Women With Lived Experience

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Eating disorders (ED) are serious illnesses that compromise the physical and psychological health of those who suffer from them. With maladaptive exercise being a common ED symptom, individuals with EDs may gravitate to fitness centres where pro‐weight loss, anti‐fat messages are the norm.
