Research on smart windows is accelerating with a global trend that emphasizes efficient energy use. VO₂ is representativematerial for thermochromic smart windows that can reflect part of sunlight depending on the external environment. We attempted to produce thermochromic thin films by ultrasonic spray coating of VO₂ nano inks. Ultrasonic spray coating is a technique that is widely used to form thin and uniform thin films, but optimization has been required due to problems such as surface roughness and coffee-ring effect. In this study, we investigated the effects of ultrasonic spray coating process conditions on the quality of VO₂ thin films, and attempted to optimize condition.

Inhalable Carbonyl Sulfide Donor-Hybridized Selective Phosphodiesterase 10A Inhibitor for Treating Idiopathic Pulmonary Fibrosis by Inhibiting Tumor Growth Factor-β Signaling and Activating the cAMP/Protein Kinase A/cAMP Response Element-Binding Protein (CREB)/p53 Axis.

Idiopathic pulmonary fibrosis (IPF) is a debilitating, incurable, and life-threatening disease that lacks effective therapy. The overexpression of phosphodiesterase 10A (PDE10A) plays a vital role in pulmonary fibrosis (PF). However, the impact of selective PDE10A inhibitors on the tumor growth factor-β (TGF-β)/small mother against decapentaplegic (Smad) signaling pathway remains unclear.

This study explored the influence of graphene oxide (GO) on morphological and mechanical properties of Nafion 115 membranes with the objective of enhancing the mechanical properties of the most widely employed membrane in Proton Exchange Membrane Water Electrolyzers (PEMWE) applications. The membrane surface was modified by ultrasonically spraying a GO solution and different annealing temperatures were tested. Scanning Electron Microscopy (SEM) cross-sectional images revealed that annealing the composite membranes was sufficient to favor an interaction between the graphene oxide and the surface of the Nafion membranes.

The aim of this study was to evaluate the efficacy and patient satisfaction of lidocaine aerosol for pain management during periodontal scaling and root planning in patients with chronic periodontitis or dental plaque-induced gingivitis. This study specifically concentrated on comparing the effectiveness of lidocaine aerosol as a topical anesthetic against a placebo, assessing its impact on pain perception during the procedure. Additionally, the relationship between periodontal treatment and the reduction of oxidative stress markers in these patients was assessed.

In the growing field of personalized medicine, non-invasive wearable devices and sensors are valuable diagnostic tools for the real-time monitoring of physiological and biokinetic signals. Among all the possible multiple (bio)-entities, pH is important in defining health-related biological information, since its variations or alterations can be considered the cause or the effect of disease and disfunction within a biological system. In this work, an innovative (bio)-electrochemical flexible pH sensor was proposed by realizing three electrodes (working, reference, and counter) directly on a polyimide (Kapton) sheet through the implementation of CO laser writing, which locally converts the polymeric sheet into a laser-induced graphene material (LIG electrodes), preserving inherent mechanical flexibility of Kapton.

Egg white protein's functional properties and digestibility can be significantly affected by processing methods. In this study, a novel combined ultrasound-heating (UH) pretreatment protocol was developed, where liquid egg white was subjected to ultrasonic treatment (0.4 W/mL, 10 min) followed by mild heating (72 °C, 10 min) prior to drying processes.
