New Insights into the Hydrogen Evolution Mechanism near the Ni/YSZ Triple Phase Boundary during Steam Electrolysis: A Patterned Model Electrode Study.

Solid oxide cell technologies play a crucial role in climate change mitigation by enabling the reversible storage of renewable energy. Understanding the electrochemical high-temperature reaction mechanisms and the catalytic role of the electrode and electrolyte materials is essential for advancing power-to-H technologies. Despite its significance, limited spectroscopic research focusing on nickel and yttria-stabilized zirconia (Ni/YSZ) is available.

Precarious but Possible: A Qualitative Study of the Landscape of Gig Work for People Living with Disabilities and Future Recommendations for Best Practices.

Introduction: The gig economy has rapidly emerged as a popular employment option, offering flexible work arrangements and opportunities for individuals seeking alternative employment. While its potential benefits are often highlighted, limited research exists on how the gig economy specifically impacts people with disabilities.

Aims: This qualitative study aims to explore and understand the experiences of individuals with disabilities who engage in gig work.

Regeneration of Ni-Zr Methane Dry Reforming Catalysts in CO: Reduction of Coking and Ni Redispersion.

Bimetallic Ni-Zr layers on top of a Zr metal substrate are oxidatively transformed into an active Ni metal-ZrO interfacial state under methane dry reforming (DRM) conditions, which exhibits progressive coking with increasing DRM cycle number and time. Complementing established anticoking catalyst- and process-design strategies, the efficiency, as well as the structural and surface-chemical consequences of the intermediate regeneration of the active state using pure CO, were studied. By combining repeated catalytic DRM testing, X-ray photoelectron spectroscopy, and chemically resolved scanning electron microscopy, we show that catalyst regeneration using the inverse Boudouard reaction not only depletes the main part of the deposited coke efficiently but also leads to an improved and particularly active catalyst state exhibiting redispersion of Ni toward small particles and optimized Ni/ZrO interfacial dimensions.

Enhancing Integrated Treatment Programs for Severe Concurrent Substance Use and Mental Disorders: Insights on Overdose from the ROAR CANADA Project: Améliorer les programmes de traitement intégré pour les troubles mentaux et les troubles liés à l'usage de substances psychoactives graves et concomitants : aperçu de la problématique des surdoses dans le cadre du projet ROAR CANADA.

Objective: This paper summarizes methods and initial overdose-related results from the Reducing Overdose and Relapse: Concurrent Attention to Neuropsychiatric Ailments and Drug Addiction (ROAR CANADA) project. ROAR CANADA is a longitudinal observational study of individuals with severe concurrent substance use and mental disorders (also called dual disorders or dual diagnosis). The study sampled patients treated at two tertiary treatment centres in British Columbia, Red Fish Healing Centre and Heartwood Centre, along with a concurrent treatment unit at St.

Combined Experimental and Theoretical Approach to the Electronic and Magnetic Properties of Cu-Doped LaMnO Perovskites.

Cu-doped LaCu Mn O perovskites have been used as a model system for a joint experimental and theoretical assessment of the influence of the Cu doping level on the structural, electronic, and magnetic properties. The different Cu-doped phases LaCuMnO (LCM37), LaCuMnO (LCM55), and LaCuMnO (LCM73) including the respective Cu- and Mn-free benchmark materials LaCuO (LC) and LaMnO (LM) have been studied by magnetization measurements and electronic paramagnetic resonance. Ferromagnetic behavior was detected for pure LM and all Cu-doped perovskites, whereas antiferromagnetic behavior was revealed for LaCuO.
