Nanotube Structure of AsPSSe ( = 0, 1).

Single-wall nanotubes of isostructural AsPSSe ( = 0, 1) are grown from solid-state reaction of stoichiometric amounts of the elements. The structure of AsPS was determined using single-crystal X-ray diffraction and refined in space group . The infinite, single-walled AsPS nanotubes have an outer diameter of ≈1.

Raman Shifts in Two-Dimensional van der Waals Magnets Reveal Magnetic Texture Evolution.

Two-dimensional (2D) van der Waals magnets comprise rich physics that can be exploited for spintronic applications. We investigate the interplay between spin-phonon coupling and spin textures in a 2D van der Waals magnet by combining magneto-Raman spectroscopy with cryogenic Lorentz transmission electron microscopy. We find that when stable skyrmion bubbles are formed in the 2D magnet, a field-dependent Raman shift can be observed, and this shift is absent for the 2D magnet prepared in its ferromagnetic state.

Comparing Oral Versus Intravenous Antibiotics Administration for Cellulitis Infection: Protocol for a Systematic Review and Meta-Analysis.

Background: Cellulitis is defined as an infection of the skin that is usually characterized by localized but poorly demarcated areas of erythema, swelling, and pain. Erysipelas is a subtype of cellulitis that is characterized by a more superficial infection, often involving the face. Because gram-positive bacteria are the most common infective agent, beta-lactam antibiotics such as cephalosporins are commonly used.

Mixed Metal Thiophosphate FeCoPS: Role of Structural Evolution and Anisotropy.

Metal chalcophosphates, MPQ (M = transition metals; Q = chalcogen), are notable among the van der Waals materials family for their potential magnetic ordering that can be tuned with an appropriate choice of the metal or chalcogen. However, there has not been a systematic investigation of the basic structural evolution in these systems with alloying of the crystal subunits due to the challenge in the diffusion process of mixing different metal cations in the octahedral sites of MPQ materials. In this work, the PS flux method was used to enable the synthesis of a multilayered mixed metal thiophosphate FeCoPS ( = 0, 0.
