To measure the proton current in a PCFC (protonic ceramic fuel cell), the proton current detector was developed using a proton conducting oxide. The amount of proton current that flowed in the PCFC can be measured by an apparatus developed based on the electromotive force of an electrochemical cell using 10 mol% In-doped CaZrO3 (hydrogen sensor) and Y-stabilized zirconia (oxygen sensor). The water vapor pressure on the cathode changed when hydrogen ions pass through the PCFC. The hydrogen ion current can be determined by monitoring the water vapor pressure. The electronic leakage was then estimated from the hydrogen ion current and external current. We measured the current of hydrogen flowing through protonic ceramic fuel cell using ytterbium-doped barium zirconate as the electrolyte. Hydrogen ions and holes were found to leak under the OCV at 700°C. The electronic leakage was found to be suppressed with the increasing electrolyte film thickness. On the other hand, no leakage of hydrogen and holes was observed at 500°C. © The Electrochemical Society.

Background: Tetracycline is an emerging contaminant in water reservoirs, causing undesirable influences on human society. The promising usage of magnetic biochar (MBC) derived from watermelon rind has been explored in the adsorption of various contaminants owing to its high specific surface area and separability;however, the temperature-dependent changes of MBC and its sorption ability toward antibiotics have not been widely examined. Method: Tunable MBCs could be synthesized via simple pyrolysis of watermelon rind impregnated with FeCl3 at different temperatures (700–900 °C). The as-synthesized MBCs were characterized using scanning electron microscopy (SEM), an elemental analyzer, N2 adsorption/desorption, Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffractometry (XRD), and vibrating sample magnetometry (VSM). Then Tetracycline, an emerging contaminant in water reservoirs, was employed as the target contaminant, while adsorption kinetics, isotherm, the effect of pH, and reusability were investigated. Significant findings: The tunability of as-synthesized MBCs could be observed by their distinct changes in structural characteristics when varying pyrolysis temperature. MBC synthesized at 900 °C (MBC900) possessed a high-specific surface area (401 m2.g−1) and saturation magnetization (55.29 emu.g−1), resulting in a greater amount of sorption sites. Tetracycline adsorption by MBCs followed a pseudo-second-order kinetic model and fitted well with the Freundlich model. MBC900 is an excellent adsorbent with a maximum adsorption capacity of 77.6 mg.g−1 and could be used for at least five cycles with an insignificant decrease in the adsorption capacity. © 2024 Taiwan Institute of Chemical Engineers

Sargassum horneri (S. horneri) is an edible species of large brown algae inhabiting along the coasts of northeastern Asia. The study focuses on the impact of celluclast enzyme extract of S. hoeneri (SHC) on various immune cell populations in splenocytes including granulocytes, macrophages, dendritic cells, and T lymphocytes. SHC alone increased the population of granulocytes and macrophages and the secretion of M1 macrophage-derived cytokines (TNF-α, IL-22), and M2 macrophage-derived cytokines (IL-4, IL-10). Interestingly, however, SHC suppressed the concanavalin A (Con A)-expanded populations of macrophages, dendritic cells, granulocytes, T and B cells, and Con A-promoted secretion of M1-macrophage derived cytokines (IFN-γ, IL-1β, TNF-α, IL-17, IL-22) and M2-macrophage derived cytokines (IL-4, IL-10, IL-13, TGF-β). SHC further restrained the Th1, Th2, and Th17 cell responses through attenuating the expression of respective transcription factors T-bet, Gata3, and Rorγt. The anti-inflammatory property of SHC is highlighted through its influence on cytokine production, particularly in the NF-κB pathway, and the attenuation of Toll-like receptor (TLR) signaling. The results reveal that SHC acts as both an immunostimulator and an inhibitor of hyperimmune reactions, showcasing its potential therapeutic applications in conditions involving dysregulated immune responses such as autoimmune diseases and inflammatory disorders. This positions SHC as a promising candidate for the development of functional ingredients with diverse applications encompassing the realms of food, pharmaceuticals, and cosmetics. © 2024

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative

Star formation rate (SFR) is a fundamental parameter for describing galaxies and inferring their evolutionary course. H II regions yield the best measure of instantaneous SFR in galaxies, although the derived SFR can have large uncertainties depending on tracers and assumptions. We present an SFR calibration for the entire molecular gas disk of the nearby Seyfert galaxy NGC 1068, based on our new high-sensitivity ALMA 100 GHz continuum data at 55 pc (= 0′′ . 8) resolution in combination with the HST Paα line data. In this calibration, we account for the spatial variations of dust extinction, electron temperature of H II regions, AGN contamination, and diffuse ionized gas (DIG) based on publicly available multi-wavelength data. Especially, given the extended nature and the possible non-negligible contribution to the total SFR, a careful consideration of DIG is essential. With a cross-calibration between two corrected ionized gas tracers (free-free continuum and Paα), the total SFR of the NGC 1068 disk is estimated to be 3.2 ± 0.5 M☉ yr−1, one-third of the SFR without accounting for DIG (9.1 ± 1.4 M☉ yr−1). We confirmed high SFR around the southern bar-end and the corotation radius, which is consistent with the previous SFR measurements. In addition, our total SFR exceeds the total SFR based on 8 µm dust emission by a factor of 1.5. We attribute this discrepancy to the differences in the young stars at different stages of evolution traced by each tracer and their respective timescales. This study provides an example to address the various uncertainties in conventional SFR measurements and their potential to lead to significant SFR miscalculations. © 2024, CC0.

environmental pollution of heavy metal(loid)s (HMs) caused adverse impacts, has become one of the emerging concerns and challenges worldwide. Metal(loid)s can pose significant threats to living organisms even when present in trace levels within environmental matrices. Extended exposure to these substances can lead to adverse health consequences in humans. Removing HM-contaminated water and moving toward sustainable development goals (SDGs) is critical. In this mission, biochar has recently gained attention in the environmental sector as a green and alternative material for wastewater removal. This work provides a comprehensive analysis of the remediation of typical HMs by biochars, associated with an understanding of remediation mechanisms, and gives practical solutions for ecologically sustainable. Applying engineered biochar in various fields, especially with nanoscale biochar-aided wastewater treatment approaches, can eliminate hazardous metal(loid) contaminants, highlighting an environmentally friendly and low-cost method. Surface modification of engineered biochar with nanomaterials is a potential strategy that positively influences its sorption capacity to remove contaminants. The research findings highlighted the biochars' ability to adsorb HM ions based on increased specific surface area (SSA), heightened porosity, and forming inner-sphere complexes with oxygen-rich groups. Utilizing biochar modification emerged as a viable approach for addressing lead (Pb), cadmium (Cd), arsenic (As), mercury (Hg), and chromium (Cr) pollution in aqueous environments. Most biochars investigated demonstrated a removal efficiency >90 % (Cd, As, Hg) and can reach an impressive 99 % (Pb and Cr). Furthermore, biochar and advanced engineered applications are also considered alternative solutions based on the circular economy. © 2024 Elsevier B.V.
