Engineering performance and environmental assessment of sustainable concrete incorporating nano silica and metakaolin as cementitious materials.

The carbon footprint associated with cement production, coupled with depletion of natural resources and climate change, underscores the need for sustainable alternatives. This study explores the effect of metakaolin (MK) and nano-silica (NS) on concrete's engineering performance and environmental impact. Initially, compressive, tensile, and flexural strength tests, along with durability assessments like water absorption, sorptivity, rapid chloride permeability, and resistance to acid and sulphate attacks, were conducted.

Facile CVD Fabrication of Vertically Aligned MoS Nanosheets with Embedded MoO on Molybdenum for High-Performance Binder-Free Lithium-Ion Battery Anodes.

The demand for compact energy storage devices necessitates the development of high-performance anode materials directly integrated with current collectors, minimizing or eliminating the need for binders or additives. With its layered structure and high theoretical capacity, molybdenum disulfide (MoS) is regarded as a promising anode material for lithium-ion batteries (LIBs). Here, we report chemical vapor deposition (CVD) growth of self-integrated, vertically aligned MoS nanosheets with embedded molybdenum dioxide (MoO) directly on a molybdenum foil and explore its potential as an anode material for LIBs.

Anesthetic Challenges in Ameloblastoma of the Mandible: A Case Report.

Ameloblastoma is a rare, locally aggressive benign tumor primarily affecting the mandible, with an incidence of 0.92 cases per million person-years and a male predominance. A two-year-old male presented with a right mandibular mass.

Effectiveness of pharmacological treatments for severe agitation in real-world emergency settings: protocol of individual-participant-data network meta-analysis.

Background: Severe psychomotor agitation and aggression often require immediate pharmacological intervention, but clear evidence-based recommendations for choosing among the multiple options are lacking. To address this gap, we plan a systematic review and individual-participant-data network meta-analysis to investigate their comparative effectiveness in real-world emergency settings with increased precision.

Methods: We will include randomized controlled trials investigating intramuscular or intravenous pharmacological interventions, as monotherapy or in combination, in adults with severe psychomotor agitation irrespective of the underlying diagnosis and requiring rapid tranquilization in general or psychiatric emergency settings.

3D bioprinted small extracellular vesicles from periodontal cells enhance mesenchymal stromal cell function.

Recent research indicates that combining 3D bioprinting and small extracellular vesicles (sEVs) offers a promising 'cell-free' regenerative medicine approach for various tissue engineering applications. Nonetheless, the majority of existing research has focused on bioprinting of sEVs sourced from cell lines. There remains a notable gap in research regarding the bioprinting of sEVs derived from primary human periodontal cells and their potential impact on ligamentous and osteogenic differentiation.
