Summary: pH-sensitive blue fluorescent carbon dots (CDs) were synthesized using Toona sinensis leaves and ethylenediamine (EDA) as raw materials, with a high fluorescence quantum yield of 17.24%. The CDs can detect urea with a limit of detection (LOD) of 6.700 mmol L-1. A ratiometric fluorescent probe (CDs@5-FAM) was constructed using CDs and 5-carboxyfluorescein (5-FAM) for more sensitive urea detection, with a low LOD of 0.014 mmol L-1. Visual intelligent detection of urea was achieved using a CDs@5-FAM probe with the help of a smartphone and RGB analysis software. The proposed method is accurate and reliable, providing a new way for rapid and visual detection of urea.

Summary: Porous activated carbon was prepared from industrial coal sludge by one-step pyrolysis and KHCO3 activation and used for phenol removal from water. The activation parameters affected the characteristics of activated carbon and phenol adsorption. CSAC-900 exhibited abundant pores and a three-dimensional structure. The adsorption of phenol on CSAC-900 was controlled by various mechanisms, and the Langmuir model described the adsorption isotherm. The maximum adsorption capacity of phenol on CSAC-900 was 305.83 mg/g. The positive ΔH and negative ΔG indicated that the adsorption was spontaneous and endothermic. Compared to commercial activated carbon, CSAC-900 showed advantages in adsorption capacity and rate, and could be regenerated and recycled.

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.
