Ultralight and Flexible Subnanowire Aerogels for Intrinsically Hydrophobic Thermal Insulation.

Aerogels are regarded as the next generation of thermal insulators; however, conventional aerogels suffer from issues such as brittleness, low moisture resistance, and a complex production process. Subnanowires (SNWs) are emerging materials known for their exceptional flexibility, toughness, intrinsic hydrophobicity, and gelling capabilities, making them ideal building blocks for flexible, tough, hydrophobic, and thermally insulating aerogels. Herein, we present a simple and scalable strategy to construct SNW aerogels by freeze-drying hydroxyapatite (HAP) SNW dispersions in cyclohexane.

Introduction: This was the first phase 1 study conducted in the United States. It consisted of dose-escalation (part A) and multiple indication-specific cohort expansion (part B), investigating the safety and preliminary efficacy of toripalimab (anti-programmed cell death-1 inhibitor) in patients with advanced malignancies.
Methods: Patients with advanced malignancies that progressed after treatment with at least one prior line of standard systemic therapy, including the patients with advanced/recurrent cholangiocarcinoma (CCA), received toripalimab 240 mg every 3 weeks in part B.
A Prospective Study of a Custom-Made Eco-Friendly Thyroid Shield: A Breakthrough in Radiation Protection.

Background The thyroid gland is the most susceptible organ to radiation during the exposure of teeth because the thyroid area appears to be within the primary beam, and the dose levels are relatively high even after using collimation. This study aims to develop an eco-friendly thyroid shield by reusing lead foils from intra-oral periapical radiographic films and evaluate its effectiveness in intraoral radiography. Methods A total of 16 patients undergoing endodontic procedures who gave written consent to participate in the study were included and divided into four categories: anterior, canine, premolar, and molar.

It features gradually changing surface resistance ( ), to expand the absorption bandwidth while maintaining high SE. Also, a folded square ring metasurface was designed to effectively suppress surface wave grating lobes, as well as to reduce the unit size of the metasurface and thus the absorber.

Recently, transparent wood (TW) has been considered for many energy-efficient building products, such as windows and decorations. However, the existing TW still faces issues with size and thickness, as well as problems with functional fillers affecting the optical and mechanical properties of TW, which limits its wide application in the window products. In this study, a wood composite material (WCM) with good optical, mechanical, and thermal insulation and UV-shielding properties was prepared by using delignified wood (DW), methyl methacrylate (MMA), and 4-vinylphenylboric acid (VPBA).
