This study aims to reduce the risk of aerosol infection in patients and healthcare workers by establishing a portable negative pressure filtering chest drainage system (PNPFCdS) that filters aerosols and microparticles. By controlling the negative pressure precisely, the system can prevent aerosol transmission under different air leaks. By using a respiratory pressure simulation platform (RPSP), it has been demonstrated that the negative pressure filtering chest drainage system can achieve a minimum measured pressure error of 1.6% without simulated intrapleural pressure changes when the air leak flow rises to 800 ml/min. When the target pressure is −1.5 kPa under simulated intrapleural pressure changes with air leak of 500 ml/min, the measured pressure change rate ranges from −16.7 % to +22.7%. When the target pressure is −9 kPa, the measured pressure change rates ranges from −2% to +6.7%. According to ISO 10079-1, this study provides a model of a negative pressure filtering chest drainage system that is effective and safe.

According to recent studies, colorectal cancer is one of the leading causes of death these days. Colorectal polyps are irregular formation of tissues that lead to colorectal cancer. Conventional methods are not sufficient to properly detect colorectal cancer in the early stages. Therefore, an efficient method is inevitable to detect and classify colorectal polyps in the early stage. In recent years, deep learning-based methods have been proposed, but there is still a need for improvement to make these methods more efficient. In this study, we have made a detailed comparison of the latest methods based on their computations and performance to propose an efficient model for real-time polyp detection. The comparison is made between deep learning based on three computation strategies: Edge Computing, General Purpose, and High Computing, using a custom colorectal dataset from a hospital. Similarly, data augmentation is also applied to analyse the performance of the mentioned techniques. We expect this study to provide insight into selecting an efficient method that would play a significant role in real-time polyp detection and classification to ensure invaluable medical aid.

The potential applications of optical sensors in biological systems, environmental monitoring, and renewable energy remain critically important. This study presents the phase inversion method for fabricating a new optical sensing membrane designed for dissolved ammonia detection. Eosin Y was embedded into composite materials of cellulose acetate (CA) and silicone rubber to enhance optical performance and modify the membrane’s structure. Luminescence quenching was used to evaluate sensing performance by measuring changes in intensity and wavelength. Eosin Y exhibited a sensitivity factor of approximately 19.15 within a detection range extending up to 480 millimolar dissolved ammonia. The results also demonstrated excellent selectivity when tested against nine different interferences, including methanol, acetic acid, and acetone. The membrane operated effectively within ph range of 3-9 and a temperature range of 20-50oC, with an average response time (t90) of approximately 20 seconds, though sensitivity decrease slightly at higher temperatures and extreme ph values. Furthermore, reduced photoexcitation of the indicator, resulting in a bathochromic shift of eosin Y by approximately 16.56 nm towards longer wavelengths. These findings highlight the potential of optical sensors for rapid and highly selective monitoring of changes in dissolved ammonia concentrations. © 2024, The Authors. All rights reserved.

Bisphenols threaten human health and sensitive detection is crucial. The present study aims to develop ternary composites of copper metal-organic framework (Cu-MOF) with Au[sbnd]Ag microstructures. The composite structure was formed by a galvanic displacement reaction and confirmed using SEM. A binder-free catalyst was used to study the electrochemical redox reaction of bisphenol A (BPA) and bisphenol S (BPS);an irreversible cyclic voltammetric signal at +0.70 V and + 0.91 V (vs. Ag/AgCl), in the dynamic range of 20 nM to 2.0 mM, and 10 nM to 1.0 mM, with limits of detection of 2.9 nM, and 3.2 nM (S/N = 3) was obtained. Practical analysis was applied to frozen tomatoes, tuna fish, milk powder, PET bottles, raw milk, and urine samples with a recovery rate of 94.00–100.80% (n = 3). Voltammetric results were validated using HPLC detection with high precision. The sensor is a promising alternative platform for measuring BPA in food samples. © 2024

This study presents the phase inversion method for fabricating a new optical sensing membrane designed for dissolved ammonia detection. Eosin Y was embedded into composite materials of cellulose acetate (CA) and silicone rubber to enhance optical performance and modify the membrane structure. Sensing performance was evaluated using luminescence quenching, which involved measuring changes in both intensity and wavelength. The fabricated membrane exhibited a microporous structure with pore diameters ranging from 1 to 10 µm, a quenching response (I₀/I₄₀₀) of 15.15, a response time (↓t₉₀) of 53 s, and effective detection at a concentration of 400 mM, a room temperature (20–25 °C), and ph 6.02, with sensing response slightly decreasing at elevated temperatures (up to 50 °C) and at ph 3.17 and 9.29. The nonlinear quenching response plot was converted into a linear form using the decibel (dB) formula, significantly improving linearity (R² = 0.9862). The membrane also exhibited excellent selectivity and the ability to detect in both gas and dissolved phases. Additionally, the sensing mechanism was investigated, revealing a combination of static and dynamic quenching, which led to an intensity decrease and a bathochromic shift of 16.56 nm. These findings highlight the potential of the developed optical sensor for rapid and highly selective ammonia monitoring in various environments. © 2025 Elsevier B.V.

Background: Fungicides, like carbendazim, have effects on male fertility. There have been sufficient studies conducted on certain chemical compounds to indicate a selective action at the epididymis level. To prevent contamination of food products with fungicides, most of the governments have established rules for the use of fungicides. However, even though this type of fungicide is primarily used in agriculture. More probably, it's contaminated with fruits and vegetables. In particular, carbendazim is one of the major fungicides in the agricultural usage Methods: This research work developed a europium vanadate (EuVO4) nanoparticle decorated carbon nanofiber (CNF) composites by hydrothermal-sonochemical approach. Based on this composite, Carbendazim sensing is developed through electrochemical oxidation based on EuVO4/f-CNF modified Glassy Carbon Electrode (GCE). By combining EuVO4 and f-CNF with the GCE, carbendazim detection can be highly effective. GCEs are rigid, making them ideal for depositing EuVO4/f-CNF, while their expansive surface area makes it possible to immobilize a greater amount of EuVO4/f-CNF, which could increase the Carbendazim sensing ability of the resulting modified GCEs with EuVO4/f-CNF. Main Findings: : The carbendazim sensing was actualized by the electrocatalytic oxidation of carbendazim on the composite modified electrode, and it is demonstrating a linear range of 0.125 to 23.875 – 33.81 to 131.375 µM with a remarkably limit of detection of 0.00612 µM. The EuVO4/f-CNF /GCE also showcased an excellent degree of stability, retaining 96.5 % of its initial activity even after 30 days. This research highlights the potential of EuVO4/f-CNF modified GCEs as robust, and efficient platform for the carbendazim detection under electrochemical approach. © 2024 Taiwan Institute of Chemical Engineers

Glass coating is an important thermal insulation technique used in the aerospace industry that serves as a thermal protection system (TPS) to protect the inner layer at elevated temperatures. This work highlights the superb mechanical and thermal properties of the B2O3-SiO2 glass systems as a surface coating for space shuttle. In the B2O3-SiO2 system, the glass transition temperature raises from 650 °C to 750 °C with increasing SiO2 content and devitrification of the α-cristobalite phase. The Al2O3 addition in B2O3-SiO2 glass can increase the glass transition temperature from 750 °C to 1000 °C and inhibit the α-cristobalite phase. The phase transition from an unstable α-cristobalite phase to an amorphous phase was achieved at 10 wt% Al2O3-added specimens. This study demonstrates that the Al2O3-B2O3-SiO2 glass (ABS glass) exhibits thermally stable behavior, making it an effective thermal barrier coating at elevated temperatures. © 2023

Water contamination is a serious environmental issue posing a significant global challenge. Roxarsone (ROX), a widely used anticoccidial drug is excreted in urine and feces, potentially disrupting natural habitats. Therefore, rapid and cost-effective ROX detection is essential. In this study, we developed a 2d sheet structure of zinc molybdate decorated on MXene (ZnMoO4/MXene) for detecting ROX using electrochemical methods. The materials were characterized using appropriate spectrophotometric and voltammetric techniques. The ZnMoO4/MXene hybrid exhibited excellent electrocatalytic performance due to its rapid electron transfer rate and higher electrical conductivity. The ZnMoO4/MXene-modified GCE (ZnMoO4/MXene/GCE) showed a broad linear range with high sensitivity (10.413 μA μМ−1 cm−2) and appreciable limit of detection (LOd) as low as 0.0081 μM. It also demonstrated significant anti-interference capabilities, excellent storage stability, and remarkable reproducibility. Furthermore, the feasibility of utilizing ZnMoO4/MXene/GCE for monitoring ROX in water samples was confirmed, achieving satisfactory recoveries. © 2024 Elsevier Ltd
