Rechargeable zinc (Zn) metal batteries are attractive for use as electrochemical energy storage systems on a global scale because of the low cost, high energy density, inherent safety, and strategic resource security of Zn metal. However, at low temperatures, Zn batteries typically suffer from high electrolyte viscosity and unfavorable ion transport properties. Here, we studied reversible Zn electrodeposition in mixtures of 1-ethyl-3-methyl-imidazolium bis(trifluoromethylsulfonyl)imide ([EMIm]TFSI) ionic liquid, γ-butyrolactone (GBL) organic solvent, and Zn(TFSI) zinc salt. The electrolyte mixtures enabled reversible Zn electrodeposition at temperatures as low as -60 °C. An electrolyte composed of 0.1 M Zn(TFSI) in [EMIm]TFSI:GBL with a volume ratio of 1:3 formed a deep eutectic solvent that optimized electrolyte conductivity, viscosity, and the zinc diffusion coefficient. Liquid-state H and C nuclear magnetic resonance (NMR) spectroscopy and molecular dynamic (MD) simulations indicate increased formation of contact ion pairs and the reduction of ion aggregates are responsible for the optimal composition.

Do you like my voice? Stakeholder perspectives about the acceptability of synthetic child voices in three South African languages.
Int J Lang Commun Disord
January 2025
Division of Communication Sciences and Disorders, University of Cape Town, Rondebosch, South Africa.
Background: There is a global need for synthetic speech development in multiple languages and dialects, as many children who cannot communicate using their natural voice struggle to find synthetic voices on high-technology devices that match their age, social and linguistic background.
Aims: To document multiple stakeholders' perspectives surrounding the quality, acceptability and utility of newly created synthetic speech in three under-resourced South African languages, namely South African English, Afrikaans and isiXhosa.
Methods & Procedures: A mixed methods research design was selected.

Vertebral fracture assessment (VFA) images from bone density machines enable the automated machine learning assessment of abdominal aortic calcification (ML-AAC), a marker of cardiovascular disease (CVD) risk. The objective of this study was to describe the risk of a major adverse cardiovascular event (MACE, from linked health records) in patients attending routine bone mineral density (BMD) testing and meeting specific criteria based on age, BMD, height loss, or glucocorticoid use have a VFA in the Manitoba Bone Mineral Density Registry. The cohort included 10 250 individuals (mean 75.

Article Synopsis
- Fluroquinolone resistance in Enterobacteriaceae, including Proteus, poses a significant public health threat, particularly affecting treatments for UTIs and intra-abdominal infections.
- The study aimed to identify specific quinolone resistance genes in ciprofloxacin-resistant Proteus species within a defined timeframe and location in Bangladesh.
- Results showed a high prevalence (64.58%) of plasmid-mediated quinolone resistance genes among resistant isolates, indicating a concerning trend that could lead to increased resistance and transmission due to over-prescription of fluoroquinolones.

Article Synopsis
- The study focuses on detecting genes linked to antibiotic resistance in multidrug-resistant gram-negative bacteria, particularly looking at beta-lactamase and aminoglycoside-modifying enzymes.
- Out of 864 gram-negative isolates, 710 were found to be multidrug-resistant, with Klebsiella pneumoniae being the most common strain.
- Results showed high prevalence of specific resistance genes, including blaTEM and blaCTX-M, emphasizing the need for molecular methods to monitor antibiotic resistance and improve treatment strategies.
