This work deals with the design of a dew point sensor based on Quartz Crystal Microbalance (QCM) without measuring the frequency. This idea is inspired by the fact that the Colpitts oscillation circuit will stop oscillating when the QCM works in the liquid media. The quartz crystal and the electrode are designed through the finite element simulation and the stop oscillating experiment is conducted to verify the sensibility. Moreover, the measurement result is calibrated to approach the true value. At last a series of dew points at the same temperature is measured with the designed sensor. Results show that the designed dew point sensor is able to detect the dew point with the proper accuracy.

Though ubiquitous in everyday life, the formation of dew on grass arises from a precise balance of environmental conditions and surface microstructure. While condensation requires sufficient atmospheric moisture availability and cooling below the dew point, the formation of stable, spherical droplets is dependent on specialized surface architectures that promote nucleation and resist total wetting. Here, a closer look at the formation, growth, and dynamics of microscale dew droplets on the surface of wheatgrass leaves, investigating the role of epicuticular wax, is provided.

All-solid-state lithium batteries (ASSLBs) represent a promising next-generation energy storage technology. While sulfide-based solid-state electrolytes (SSEs) offer high ionic conductivity, their practical application is hindered by inherent instability issues. To further enhance the performance, Pauling's rules are considered.

Purpose: The primary aim of this preliminary study was to examine the potential advantages and disadvantages of using ChatGPT-3.5 (free version) to obtain information pertaining to the discipline of communication sciences and disorders (CSD).
Method: Nine university-based CSD researchers with expertise in different topic areas created questions of varying complexity (basic, advanced, evidence-based practice [EBP], and general CSD) to ask ChatGPT and then rated the software's responses for accuracy (6-point Likert scale) and completeness (3-point Likert scale).

This study investigates the effect of surface oxide control on the phosphatability of ultra-high-strength steel (UHSS) for automotive applications. Surface oxides were manipulated by adjusting the dew point to -50 °C and 0 °C during the annealing process, and the corresponding changes in phosphating behavior were examined. The surface characteristics of the samples were analyzed using X-ray photoelectron spectroscopy (XPS) and field-emission transmission electron microscopy (FE-TEM), while the phosphatability of the samples was evaluated through electrochemical measurements.

The development of solid-state batteries (SSBs) that do not use hazardous materials as electrolytes and are not flammable is progressing rapidly, however the production of sulfide-based SSBs requires strict low-dew-point control due to their high reactivity with atmospheric moisture and the concern of generating hydrogen sulfide, and several issues remain in terms of the cost and recyclability. Thus, low-cost facile materials and low-CO-emission processes are necessary. With regard to oxide-type SSBs, which are attracting attention for their safety, there are issues with manufacturing suitability, as high-temperature sintering of oxide solid electrolyte particles is required.
