Rapid Characterization of Point Defects in Solid-State Ion Conductors Using Raman Spectroscopy, Machine-Learning Force Fields, and Atomic Raman Tensors.

The successful design of solid-state photo- and electrochemical devices depends on the careful engineering of point defects in solid-state ion conductors. Characterization of point defects is critical to these efforts, but the best-developed techniques are difficult and time-consuming. Raman spectroscopy─with its exceptional speed, flexibility, and accessibility─is a promising alternative.

Influence of Sr-Site Deficiency, Ca/Ba/La Doping on the Exsolution of Ni from SrTiO.

Cermet catalysts formed via exsolution of metal nanoparticles from perovskites promise to perform better in electro- and thermochemical applications than those synthesized by conventional wet-chemical approaches. However, a shortage of robust material design principles still stands in the way of widespread commercial adoption of exsolution. Working with Ni-doped SrTiO solid solutions, we investigated how the introduction of Sr deficiency as well as Ca, Ba, and La doping on the Sr site changed the size and surface density of exsolved Ni nanoparticles.

Community reinforcement approach (CRA) supported with structured recreation therapy: Experiences of people living with HIV in a pilot substance use treatment program at a specialty hospital.

Introduction: Community reinforcement approach (CRA) is a behavioral intervention that has demonstrated favorable treatment outcomes for individuals with substance use disorders across studies. CRA focuses on abstinence; however, abstinence is not a desired goal among all people who use substances. Previous research has called for harm reduction-oriented treatment programs, especially within hospital settings.

Philanthropic donor perspectives about providing harm reduction services for people living with HIV/AIDS in a hospital setting.

Background: Hospital-based harm reduction services are needed to reduce drug-related harms, facilitate retention in care, and increase medical treatment adherence for people who use drugs. Philanthropic donor support plays a key role in delivering such innovative services which might fall outside current funding streams. However, little is known about how the principles, implementation, and practice of harm reduction services, which are often highly stigmatized, may impact donor behaviours.

A structuration theory guided analysis of the hospitalization experience for people living with HIV who use drugs: My rules and their rules.

People living with HIV (PLWH) who use drugs in harmful amounts, types and/or modes of consumption (e.g., drugs from unregulated sources) experience barriers to accessing conventional healthcare services.
