Formation of Twin-Free Single Phase β-InSe Layers via Selenium Diffusion into InP(111)B Substrate.

Indium selenide, InSe, has recently attracted growing interest due to its remarkable properties, including room temperature ferroelectricity, outstanding photoresponsivity, and exotic in-plane ferroelectricity, which open up new regimes for next generation electronics. InSe also provides the important advantage of tuning the electrical properties of ultrathin layers with an external electrical and magnetic field, making it a potential platform to study novel two-dimensional physics. Yet, InSe has many different polymorphs, and it has been challenging to synthesize a single phase material, especially using scalable growth methods, as needed for technological applications.

Understanding the impact of Bi stoichiometry towards optimised BiFeO photocathodes: structure, morphology, defects and ferroelectricity.

BiFeO thin films have been widely studied for photoelectrochemical water splitting applications because of its narrow bandgap and good ferroelectricity which can promote the separation of photo-generated charges. Bismuth is well known as a volatile element and excess bismuth is usually added into the precursor to compensate the loss of bismuth during heat treatment, but the amount of excess bismuth required and how excess bismuth will affect PEC performance have not been clearly studied. Herein, self-doped Bi FeO thin films are prepared simple chemical solution deposition method with excess bismuth from 0-30% in the precursor.

Silk-Hyaluronic Acid for Vocal Fold Augmentation: Safety Profile and Long-Term Voice Outcomes.

Objectives: Silk-hyaluronic acid (silk-HA) is a novel vocal fold augmentation material used in humans since July 2020. We aim to describe indications, voice outcomes, and longevity data for silk-HA injectable when used for vocal fold injection (VFI) augmentation in a large cohort of patients with longer-term follow-up than preliminary clinical studies.

Methods: Retrospective chart review of Silk-HA injections for glottic insufficiency (GI) and follow-up between July 2020 and November 2023.

Validation of a Novel Allergy-Specific Domain for the 22-Item Sino-Nasal Outcomes Test.

Objectives: To develop and assess the validity of a novel allergy-specific domain for the 22-item sino-nasal outcomes test (SNOT-22), to provide a new tool that efficiently quantifies the impact of allergic rhinitis (AR) concurrent with chronic rhinosinusitis.

Study Design: Prospective validation study.

Setting: Tertiary care hospital and community-based clinic.
