Seeking new and efficient thermoelectric materials requires a detailed comprehension of chemical bonding and structure in solids at microscopic levels, which dictates their intriguing physical and chemical properties. Herein, we investigate the influence of local structural distortion on the thermoelectric properties of TlCuS, a layered metal sulfide featuring edge-shared Cu-S tetrahedra within CuS layers. While powder X-ray diffraction suggests average crystallographic symmetry with no distortion in CuS tetrahedra, the synchrotron X-ray pair distribution function experiment exposes concealed local symmetry breaking, with dynamic off-centering distortions of the CuS tetrahedra.

- The study focuses on Kcoronene, a potassium-intercalated polycyclic aromatic hydrocarbon, detailing its synthesis, structure, and magnetic properties while outlining a computational method to identify suitable PAHs for metal intercalation.
- Coronene was selected based on a screening of its electronic structure and available void space, demonstrating stability when intercalated with three potassium ions per coronene molecule.
- Despite structural changes and disorder caused by potassium intercalation, Kcoronene did not exhibit superconductivity, which contrasts with earlier findings and may be linked to the extensive structural disruption observed.
Background And Aim: Recent studies have shown that electronic cigarettes (ECs) use disrupts the oral microbiome composition and diversity, impairing the metabolic pathways of the mucosal cells. However, to date, no reports have evaluated the role of EC exposure in the context of oral metabolome. Hence, the aim of this study was to investigate the role of EC aerosol exposure in the dysregulation of the oral microbiome and metabolome profile using in vitro 3D organotypic models of human oral mucosa.

Objective: Clinicopathologic illustration of sinonasal teratocarcinosarcoma (SNTCS) in a middle-aged man, highlighting the difficulties and challenges encountered during surgical intervention, histopathologic diagnosis, and its overall management.
Methodology: Case report and literature review.
Results: A 40-year-old man having recurrent epistaxis for three months presented with a dark-colored protruding polypoid nasal mass.
Background: An endoscopic screening program following successful weaning from prolonged mechanical ventilation maintained through endotracheal tube (ET; ) may be justified to assess the upper (laryngotracheal) airway in children who may not always be symptomatic for intubation-related complications.
Objectives: To evaluate effects of prolonged intubation in children through endoscopic screening of the laryngotracheal airway.
Methods: In this cross-sectional pilot project, children (2 months-12 years) successfully extubated following prolonged intubation were selected, irrespective of having symptoms, for a 1-time flexible nasolaryngoscopy at third to sixth month post-extubation (follow-up window).
