Nitrogen-doped carbon dots (NCds) featuring primary pyrrolic N and pyridinic N dominated configurations were prepared using hydrothermal (H-NCds) and microwave (M-NCds) methods, respectively. These H-NCds and M-NCds were subsequently applied to decorate CsPbBr3 nanocrystals (CPB NCs) individually, using a ligand-assisted reprecipitation process. Both CPB/M-NCds and CPB/H-NCds nanoheterostructures (NHSs) exhibited S-scheme charge transfer behavior, which enhanced their performance in photocatalytic CO2 reduction and selectivity of CO2-to-CH4 conversion, compared to pristine CPB NCs. The presence of pyrrolic N configuration at the heterojunction of CPB/H-NCds facilitated efficient S-scheme charge transfer, leading to a remarkable 43-fold increase in photoactivity. In contrast, CPB/M-NCds showed only a modest 3-fold enhancement in photoactivity, which was attributed to electron trapping by pyridinic N at the heterojunction. The study offers crucial insights into charge carrier dynamics within perovskite/carbon NHSs at the molecular level to advance the understanding of solar fuel generation. © 2024 American Chemical Society.

The use solar photovoltaic technology, as one of renewable sources for energy production, is currently experiencing a strong development all over the world, being a sustainable, environmentally friendly, affordable, and easy to implement solution. The amount of energy produced, and the efficiency of photovoltaic panels are influenced by a series of factors that can be intrinsic, external, or environmental. To increase the efficiency of photovoltaic panels and their lifespan, it is important that the parameters with a direct influence be taken into consideration. These influencing factors include ambient temperature, solar panel temperature, direct solar irradiation, wind speed, altitude, atmospheric pressure, and local stressors such as shading, dust accumulation and pollution. Among them shading has been identified as a significant concern. Shading, either permanent or temporary, can significantly reduce the electricity generation capacity of photovoltaic panels. This article aims to investigate the impact of shading on a photovoltaic panel's performance, focusing on parameters such as output power, voltage and electrical current, as well as its efficiency. Through a series of computational simulations and experimental investigations, the research quantifies the impact of partial cell shading while also exploring photovoltaic panels shading mitigation strategies. © 2024 IEEE.

Improving ionic conductivity of von-Alpen-type NASICON ceramic electrolytes via magnesium doping

NASICON (sodium (Na) superionic conductor) compounds have attracted considerable attention as promising solid electrolyte materials for advanced Na-based batteries. In this study, we investigated the improvement in ionic conductivities of von-Alpen-type NASICON (vA-NASICON) ceramic electrolytes by introducing a magnesium ion (Mg^(2+)) as a heterogeneous element. The optimal Mg-doped vA-NASICON exhibited a high ionic conductivity of 3.64×10^(−3) S·cm^(−1), which was almost 80% higher than that of un-doped vA-NASICON. The changes in physicochemical properties of the vA-NASICONs through the Mg introduction were systematically analyzed, and their effects on the ionic conductivities of the vA-NASICON were studied in detail. When the optimal ratio of Mg^(2+) was used in a synthetic process, the relative density (96.6%) and grain boundary ionic conductivity (σgb) were maximized, which improved the total ionic conductivity (σt) of the vA-NASICON. However, when Mg^(2+) was introduced in excess, the ionic conductivity decreased because of the formation of an undesired sodium magnesium phosphate (NaxMgyPO_(4)) secondary phase. The results of this study are expected to be effectively applied in the development of advanced sodium-based solid electrolytes with high ionic conductivities.

Mongolian medicine Garidi-5 is a well-known regional compound formulation used for drying and treating the disease of yellow water. It contains the toxic herb Cao Wu and has been in use till date. Biochemical indicators in mice are important for studying drug toxicity. In this study, 32 Sd rats were divided into four groups and given a daily oral dose of Garidi-5 at 0 g/kg, 0.3429 g/kg, 0.0857 g/kg, and 0.0214 g/kg, respectively, for 28 consecutive days. A feature selection algorithm based on the reliefF algorithm was used to identify Garidi-5 poisoning in rats using organ indicators and blood biochemical indicators. In terms of feature selection, the most important relevant indicators were CKMB, ALP, HWr, CrEP, CK, UrEA, ALT, and L2Wr. The K-means algorithm was used to perform cluster analysis on the rats' data indicators, and the results showed that after using the reliefF algorithm for feature selection, the predicted accuracy and silhouette coefficient increased by 21.43% and 0.0779, respectively, when the feature weight threshold was set to 0.035. Empirical analysis showed that the reliefF feature selection algorithm can improve the accuracy of toxicity prediction. © 2024 IEEE.

A hollow fiber nanofiltration (NF) membrane fabricated on poly(vinyl chloride) (PVC) substrate was studied for the removal of chemicals of concern (CoCs). The functional layer of the hollow fiber NF membrane was fabricated via interfacial polymerization of piperazine (PIP) and trimesoyl chloride (TMC) on the lumen side of the PVC ultrafiltration membrane. A gas sweeping method was employed during the fabrication of the NF functional layer and was assessed based on the separation performance of the NF membrane. It was found that the sweeping gas could increase the performance of the NF membrane, which is also affected by the concentration of PIP and TMC solutions. NF membranes prepared under optimized gas sweeping conditions had a Pb(NO3)2 rejection of 93% and a flux of about 24 L·m-2·h-1. The rejections to Na2SO4, MgSO4, NaCl, glucose, and sucrose were 96.5, 95.3, 53.7, 91.7, and 98.2%, respectively. Moreover, the results of spike tests show that the NF membrane could effectively reject the incident CoCs up to eight times the regulated values. © 2023 American Chemical Society.
