Revitalizing interphase in all-solid-state Li metal batteries by electrophile reduction.

Nat Mater

January 2025

Department of Materials Science and Engineering, University of Maryland, College Park, MD, USA.

All-solid-state lithium metal batteries promise high levels of safety and energy density, but their practical realization is limited by low Li reversibility, limited cell loading and demand for high-temperature and high-pressure operation, stemming from solid-state electrolyte (SSE) low-voltage reduction and high-voltage decomposition, and from lithium dendrite growth. Here we concurrently address these challenges by reporting that a family of reductive electrophiles gain electrons and cations from metal-nucleophile materials (here a Li sulfide SSE) upon contact to undergo electrochemical reduction and form interphase layers (named solid reductive-electrophile interphase) on material surfaces. The solid reductive-electrophile interphase is electron blocking and lithiophobic, prevents SSE reduction, suppresses Li dendrites and supports high-voltage cathodes.

Background: Depression significantly impacts an individual's thoughts, emotions, behaviors, and moods; this prevalent mental health condition affects millions globally. Traditional approaches to detecting and treating depression rely on questionnaires and personal interviews, which can be time consuming and potentially inefficient. As social media has permanently shifted the pattern of our daily communications, social media postings can offer new perspectives in understanding mental illness in individuals because they provide an unbiased exploration of their language use and behavioral patterns.

Introduction: Feedback literacy (FBL) is a critical skill for learners encompassing four behaviors: appreciating feedback, making judgements, managing affect, and taking action. Little guidance has been available for clinical preceptors to promote FBL. The R2C2 feedback and coaching model that guides teachers through building Relationships, exploring Reactions and Reflections, discussing Content and Coaching to co-develop an action plan for follow-up may support FBL.

Macrophages are an integral part of the innate immune system and act as a first line of defense to pathogens; however, macrophages can be reservoirs for pathogens to hide and replicate. Tuberculosis, influenza virus, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are common diseases whose pathogens are uptaken into macrophages. Current treatments for diseases such as these are limited by the therapeutic delivery method, which typically involves systemic delivery in large, frequent doses.

Methods for data extraction and data transformation in convergent integrated mixed methods systematic reviews.

JBI Evid Synth

January 2025

The University of West London Centre for Evidence-Based Healthcare: A JBI Centre of Excellence, College of Nursing, Midwifery and Healthcare, University of West London, London, United Kingdom.

Objective: The objective of this guidance paper is to describe data transformation involving qualitization, including when and how to undertake this process, and to clarify how it aligns with data extraction in order to expand on the current guidance for JBI convergent integrated mixed methods systematic reviews (MMSRs).

Introduction: The convergent integrated approach to MMSRs involves combining extracted data from both quantitative studies (including the quantitative components of mixed methods studies) and qualitative studies (including the qualitative components of mixed methods studies). This process requires data transformation, which can occur either by converting qualitative data into quantitative data (ie, quantitizing) or converting quantitative data into qualitative data (ie, qualitizing).

Natural organic matter (NOM) in rivers is an important energy source to sustain aquatic ecosystem health. However, in surface water supply systems where chlorination is often used for disinfection, NOM is also a precursor for the carcinogenic and mutagenic disinfection byproducts such as trihalomethanes and haloacetic acids. Effective management of NOM in rivers to maintain both aquatic ecosystem functions and high-quality water supply requires better understanding of the NOM transport patterns.

The manner in which neural activity unfolds over time is thought to be central to sensory, motor and cognitive functions in the brain. Network models have long posited that the brain's computations involve time courses of activity that are shaped by the underlying network. A prediction from this view is that the activity time courses should be difficult to violate.

Dual inhibition of the angiopoietin (Ang)/Tie and vascular endothelial growth factor (VEGF) signalling pathways in patients with retinal diseases, such as neovascular age-related macular degeneration (nAMD) and diabetic macular oedema (DME), may induce greater vascular stability and contribute to increased treatment efficacy and durability compared with treatments that only target the VEGF pathway. Faricimab, a bispecific intravitreal agent that inhibits both VEGF and Ang-2, is the first injectable ophthalmic drug to achieve treatment intervals of up to 16 weeks in Phase 3 studies for nAMD and DME while exhibiting improvements in visual acuity and retinal thickness. Data from real-world studies have supported the safety, visual and anatomic benefits and durability of faricimab, even in patients who were previously treated with other intravitreal agents.

Spasticity affects up to 80% of individuals with cerebral palsy and can lead to pain and difficulties with performing activities of daily living. If left untreated, spasticity can progress to contracture and neuro-orthopedic deformities. Cryoneurolysis is an emerging and mini-invasive ultrasound-guided technique that causes secondary axonotmesis of peripheral nerves through the formation of an ice ball and may result in months to years of improved range of motion and reduced pain in patients with spasticity.
