Summary: In order to achieve a high separation efficiency of photogenerated carriers in semiconductors, constructing high-quality heterogeneous interfaces as charge flow highways is critical and challenging. This study successfully demonstrates a new strategy for constructing high-quality heterogeneous interfaces by consciously modulating interfacial chemical bonds and internal electric fields (IEFs) in a 0D/0D/1D-Co3O4/TiO2/sepiolite composite catalyst. The results show that the interfacial Co2+-O-Ti bond plays a major role as an atomic-level charge transport channel at the p-n junction, and increasing the Co2+/Co3+ ratio enhances the IEF intensity, thereby enhancing the photoelectron separation and migration efficiency. The study also shows the efficient synergy between photocatalysis and peroxymonosulfate activation for deep pollutant degradation and reduced ecotoxicity.

Summary: This study aimed to prepare transparent defective p-type TiO2 films via the hydrothermal method by introducing metal vacancies (V-Ti) into undoped oxide, resulting in the formation of a p-n homojunction diode. The defective TiO2 films exhibited p-type conductivity and high charge mobility. The influence of growth time on the morphological, structural, and optical properties of TiO2 nanorods was analyzed using FESEM, XRD, XPS, and UV-VIS methods. The results showed that the films had a grass-like nanostructure and a stoichiometry ratio of Ti to O of 2:1. The optical properties of the films were investigated, revealing changes in transmittance, absorbance, and energy gap with varying growth times. The p-n homojunction exhibited distinct diode-like behavior. These findings have significant implications for the development of metal-oxide solar cells, photo-catalysts, LEDs, photodiodes, and photo-electrochemical devices.

Summary: This study identified 372 differentially expressed circRNAs in peripheral blood mononuclear cells (PBMCs) of children with asthma. Among them, a circRNA called circS100A11 was highly expressed in monocytes and significantly upregulated in children with asthma. Further experiments demonstrated that circS100A11 promoted M2a macrophage activation by enhancing translation of its host gene, S100A11, and exacerbated lung inflammation in a mouse model of asthma. The study also found that circS100A11 competitively bound to CAPRIN1 to promote S100A11 translation, thereby enhancing M2a macrophage activation.

Summary: This study retrospectively analyzed the clinical characteristics and underlying causes of 551 hospitalized children with recurrent pneumonia from January 2016 to January 2021 at the Children's Hospital of Fudan University. The majority (87.7%) of the children had underlying causes, with recurrent aspiration, primary immunodeficiency, and congenital heart diseases being the most common. Genetic defects were identified in about a quarter of the patients. Primary immunodeficiency, primary ciliary dyskinesia, bronchiolitis obliterans, and the age of >3 years at diagnosis were risk factors for severe outcomes. Aspiration and an abnormal family history were risk factors for rehospitalization.

Summary: In this paper, a new run-time monitoring technique is proposed to detect hardware Trojans (HT) on working field-programmable gate array (FPGA), which can enhance the hardware security of IoT devices. The technique places multiple temperature sensors on FPGA and collects their values at each time interval. A predictive model is constructed to estimate the real-time distribution of sensor frequency. If the difference between the predicted value and the real one exceeds a dynamically updated threshold, an HT activation is reported. The experiment results demonstrate that the technique achieves high detection accuracy (>= 98%), low false negative ratio (<= 1.5%), and zero false positive ratio under various FPGA HT benchmarks.
