Assessment of the chemical solubility of experimental and commercial lithium silicate glass-ceramics.
Dent Mater
January 2025
Department of Restorative Dentistry, University of Manitoba, Winnipeg, MB, R3E 0W2, Canada.
Objective: This study aimed to evaluate the chemical solubility (CS) and conduct a comprehensive physicochemical characterization of several experimental and commercial lithium silicate-based glass-ceramics towards an understanding of the chemical processes governing dissolution in these glass-ceramics.
Methodology: Glass-ceramic (GC) samples were categorized into two groups: experimental materials featuring lithium metasilicate crystals (GCE1 and GCE2); and five commercial brands relying mostly on lithium disilicate (Celtra®Duo, IPS e.max®CAD, Straumann®n!ce®, CEREC Tessera™, and VITA Suprinity®).
Co-evolutionary dynamics of microbial communities and flavor profiles during natural fermentation of Cabernet Sauvignon and Merlot: A comparative study within a single vineyard.

Indigenous microorganisms play a crucial role in determining the quality of naturally fermented wines. However, the impact of grape cultivar specificity on microbial composition is often overshadowed by the geographical location of the vineyard, leading to underestimation of its role in natural wine fermentation. Therefore, this study focuses on different grape cultivars within a single vineyard.

The practical application of polyethylene glycol (PEG) phase change materials (PCMs) necessitates exceptional shape stability, rapid thermal responsiveness, and a substantial thermal storage capacity. The present study focuses on the fabrication of a highly robust cellulose nanofibril (CNF) based aerogel with an ordered structure, serving as a three-dimensional (3D) scaffold for PEG to effectively prevent any potential leakage. Additionally, hydroxyl and amino functional groups are introduced to functionalize boron nitride nanosheets (BNNS-g), which are incorporated into the aerogel to enhance its thermal conductivity.

It is currently uncertain how selection of more efficient animals might impact other traits such as resilience (which, in this context, is defined as the ability of an animal to sustain or revert quickly to its previous production level and health status after a disturbance), especially in small ruminants. However, improving, or at least maintaining, resilience is of utmost importance to ensure livestock production in the face of external perturbances, which are expected to become more prevalent in the near future due to climate change and global instability. This study was conducted to investigate whether a nutritional challenge consisting of animals receiving only 70% of their voluntary feed intake (DMI) for 26 d, might differentially affect the response of high- and low-feed efficiency (FE) sheep.

Background: The aim of this study was to analyze the histomorphometric findings of autogenous tooth grafting (ATG) for alveolar ridge preservation (ARP), using graft material from extracted teeth. Variations by sex, age and location of extracted teeth, as well as any associated complications, were also assessed.
Materials And Methods: This prospective, single-cohort study was conducted using ATG placed in extraction sockets.
