    Abstract Oxidative dehydrogenation of propane (ODHP) is a promising process for producing propene. Recently, some boron-based catalysts have exhibited excellent olefin selectivity in ODHP. However, their complex synthetic routes and poor stability under high-temperature reaction conditions have hindered their practical application. Herein, we report a self-evolution method rather than conventional assembly approaches to acquire structures with excellent stability under a high propane conversion, from a single precursor-MgB

    Abstract Self-compacting mortar (SCM) has superior workability and long-term durable performance compared to traditional mortar. The strength of SCM, including both its compressive and flexural strengths, is a crucial property that is determined by appropriate curing conditions and mix design parameters. In the context of materials science, predicting the strength of SCM is challenging because of multiple influencing factors. This study employed machine learning techniques to establish SCM strength prediction models. Based on ten different input parameters, the strength of SCM specimens were predicted using two different types of hybrid machine learning (HML) models, namely Extreme Gradient Boosting (XGBoost) and the Random Forest (RF) algorithm. HML models were trained and tested by experimental data from 320 test specimens. In addition, the Bayesian optimization method was utilized to fine tune the hyperparameters of the employed algorithms, and cross-validation was employed to partition the database into multiple folds for a more thorough exploration of the hyperparameter space while providing a more accurate assessment of the model's predictive power. The results show that both HML models can successfully predict the SCM strength values with high accuracy, and the Bo-XGB model demonstrated higher accuracy (R

    Abstract Crystalline borates have received great attention due to their various structures and wide applications. For a long time, the corner-sharing B–O unit is considered a basic rule in borate structural chemistry. The Dy 4 B 6 O 15 synthesized under high-pressure is the first oxoborate with edge-sharing [BO 4 ] tetrahedra, while the KZnB 3 O 6 is the first ambient pressure borate with the edge-sharing [BO 4 ] tetrahedra. The edge-sharing connection modes greatly enrich the structural chemistry of borates and are expected to expand new applications in the future. In this review, we summarize the recent progress in crystalline borates with edge-sharing [BO 4 ] tetrahedra. We discuss the synthesis, fundamental building blocks, structural features, and possible applications of these edge-sharing borates. Finally, we also discuss the future perspectives in this field.

    Abstract Commonly, SiGe is considered as a typical thermoelectric material with a favorable performance in the high temperature region. Here, we report a new strategy through the addition of the nano-second-phase B₂O₃ into SiGe via ball milling and spark plasma sintering technique, aiming to realize high thermoelectric performance in the medium temperature region. By controlling the amount of B₂O₃ added to the SiGe matrix, the thermal conductivity is greatly reduced because of the compound effects of the nano-second-phase and beneficial microstructure. Simultaneously, the power factors are also enhanced, resulting in a high ZT of 1.47 of the p-type B₂O₃/SiGe bulk composite at 873 K. Our ZT values are 116% higher than the typical materials used in radio-isotope thermoelectric generators (RTGs), and show 104% enhancement over the p-type SiGe alloys in the present study. This study opens a new way to widen and improve the thermoelectric performance for narrow temperature region materials, and is especially highly effective for the environmentally friendly SiGe materials.
