Signatures of ambient pressure superconductivity in thin film LaNiO.

Recently, the bilayer nickelate LaNiO has been discovered as a new superconductor with transition temperature T near 80 K under high pressure. Despite extensive theoretical and experimental work to understand the nature of its superconductivity, the requirement of extreme pressure restricts the use of many experimental probes and limits its application potential. Here we present signatures of superconductivity in LaNiO thin films at ambient pressure, facilitated by the application of epitaxial compressive strain.

Emergent layer stacking arrangements in c-axis confined MoTe.

The layer stacking order in 2D materials strongly affects functional properties and holds promise for next-generation electronic devices. In bulk, octahedral MoTe possesses two stacking arrangements, the ferroelectric Weyl semimetal T phase and the higher-order topological insulator 1T' phase. However, in thin flakes of MoTe, it is unclear if the layer stacking follows the T, 1T', or an alternative stacking sequence.

Nanoceria Aggregate Formulation Promotes Buffer Stability, Cell Clustering, and Reduction of Adherent Biofilm in .

is one of the key etiological factors in tooth-borne biofilm development that leads to dental caries in the presence of fermentable sugars. We previously reported on the ability of acid-stabilized nanoceria (CeO-NP) produced by the hydrolysis of ceric salts to limit biofilm adherence of non-bactericidal mechanism(s). Herein, we report a chondroitin sulfate A (CSA) formulation (CeO-NP-CSA) comprising nanoceria aggregates that promotes resistance to bulk precipitation under a range of conditions with retention of the biofilm-inhibiting activity, allowing for a more thorough mechanistic study of its bioactivity.

Distinct compartmentalization of immune cells and mediators characterizes bullous pemphigoid disease.

Bullous pemphigoid (BP) is an autoimmune blistering disease characterized by recruitment of leucocytes into skin and release of damaging enzymes, resulting in epidermal detachment and blister formation. To better understand the role of leukotriene B4 (LTB4) and other inflammatory factors in BP pathophysiology, we conducted microscopic and immunohistochemical analyses of preserved skin biopsy sections and conducted flow cytometry and ELISA analyses of matched blood and blister fluid from BP patients. Neutrophils predominated in BP blister fluid, which also contained monocytes/macrophages and T cells, but few to no eosinophils and B cells.

Hydrolyzed Ce(IV) salts limit sucrose-dependent biofilm formation by Streptococcus mutans.

Several studies have focused on the antimicrobial effects of cerium oxide nanoparticles (CeO-NP) but few have focused on their effects on bacteria under initial biofilm formation conditions. Streptococcus mutans is a prolific biofilm former contributing to dental caries in the presence of fermentable carbohydrates and is a recognized target for therapeutic intervention. CeO-NP derived solely from Ce(IV) salt hydrolysis were found to reduce adherent bacteria by approximately 40% while commercial dispersions of "bare" CeO-NP (e.
