Objective: To determine the performance of different processing solutions using an automatic processor for dental radiography.

Study Design: One brand of dental X-ray film (Minimax, Chicago, IL, USA) was developed in an automatic processor using four different brands of processing solution: Megasan (MGS, Megasan, Ankara, Turkey), (HAC, Ankara, Turkey), Fuji (Fuji Medical, Hacettepe Cedex, France) and RP X-Omat (Eastman Kodak, Rochester, NY, USA) at a range of temperatures. Performance was evaluated with respect to base plug fog density, relative speed and contrast.

Results: All solutions produced acceptable base plus fog values. MGS produced significantly greater densities (P < 0.05) than the other three solutions. Contrast obtained with Kodak and Fuji solutions was less than with MGS and HAC. Developing temperature recommended by the manufacturer of the processor were found to be higher than that needed to achieve a clinically acceptable film.

Conclusions: Depending on the processor and processing solutions used, exposure time and processing temperature can be modified while maintaining image quality. The cheapest processing solution (MGS) gave the same results as the more expensive.

To facilitate on-site detection by nonspecialists, there is a demand for the development of portable "sample-to-answer" devices capable of executing all procedures in an automated or easy-to-operate manner. Here, we developed an automated detection device that integrated a magnetofluidic manipulation system and a signal acquisition system. Both systems were controllable via a smartphone.

Laboratory-scale spin-coating techniques are widely employed for fabricating small-size, high-efficiency perovskite solar cells. However, achieving large-area, high-uniformity perovskite films and thus high-efficiency solar cell devices remain challenging due to the complex fluid dynamics and drying behaviors of perovskite precursor solutions during large-area fabrication processes. In this work, a high-quality, pinhole-free, large-area FAPbI perovskite film is successfully obtained via scalable blade-coating technology, assisted by a novel bidirectional Marangoni convection strategy.

Cellular senescence contributes to inflammation and organ dysfunction during aging. While this process is generally characterized by irreversible cell cycle arrest, its morphological features and functional impacts vary in different cells from various organs. In this study, we examined the expression of multiple senescent markers in the lungs of young and aged humans and mice, as well as in mouse lung endothelial cells cultured with a senescence inducer, suberoylanilide hydroxamic acid (SAHA), or doxorubicin (DOXO).

Metal halide perovskite semiconductors have attracted considerable attention because they enable the development of devices with exceptional optoelectronic and electronic properties via cost-effective and high-throughput chemical solution processes. However, challenges persist in the solution processing of perovskite films, including limited control over crystallization and the formation of defective deposits, leading to suboptimal device performance and reproducibility. Tin (Sn) halide perovskite holds promise for achieving high-performance thin-film transistors (TFTs) due to its intrinsic high hole mobility.
