Summary: Micro-supercapacitor (MSC) electrodes made of porous graphene/SiC composite films grown by laser CVD exhibit high specific capacitance and excellent cycling stability. The specific capacitance reaches up to 219.3 mF/cm2, which is 26 times higher than that of electrodes prepared by conventional CVD. After 20000 charge-discharge cycles, the electrode retains 99.9% capacitance at room temperature and 109.6% capacitance at variable temperatures. The abundance of graphene on the SiC porous structure and the strong adhesion between graphene and SiC contribute to the capacitance enhancement and cycling stability.

Summary: Nanostructured manganese dioxide (MnO2) was homogeneously deposited on a regenerated cellulose/functionalized CNT (f-CNT) matrix through a direct redox reaction between potassium permanganate and carbon nanotubes (CNTs) in an acidic medium. The resulting cellulose/f-CNT/MnO2 composite films showed outstanding electrochemical performance as freestanding electrodes for supercapacitors, with a maximal areal capacitance of 7956 mF cm(-2) achieved for a high MnO2 content composite. The symmetric supercapacitor assembled using the cellulose/f-CNT/MnO2 composite film exhibited high capacitance, energy density, and power density.

Summary: By training and employing BP-ANN, the multistage oxidation behavior of aluminum silicon carbide (Al4SiC4) was investigated, considering the oxidation temperature, time, and aspect ratio. The results showed that the BP-ANN model can accurately and efficiently simulate the oxidation behavior of Al4SiC4 powders with different reaction laws. In addition, the extrapolation ability of the BP-ANN model allows for maintaining high accuracy and expanding the experimental data to 1.2 times the original range with a coefficient of determination >= 0.801. By incorporating a real physical picture model developed by the research group, the experimental data can be further expanded to 2.2 times. This study provides a new path for understanding the oxidation behavior of materials with multistage oxidation.

Summary: Researchers have developed an electrical label-free detection method using a remote floating-gate field-effect transistor (RFGFET) with a 2-dimensional reduced graphene oxide (rGO) sensing membrane to detect SARS-CoV-2. The RFGFET sensors showed rapid detection (<5 min), high accuracy (90.6%), and low variation (<6%) when tested with nasal swab samples. The detection limit of the RFGFET sensors for pseudo-SARS-CoV-2 was 10,000 times lower than enzyme-linked immunosorbent assays and comparable to reverse transcription-polymerase chain reaction (RT-PCR) for patient samples. This research has significant implications for rapid SARS-CoV-2 diagnostics.

Summary: Diatomite-modified wood ceramics (DMWCs) were successfully prepared as an adsorbent to remove hydroquinone from wastewater. The adsorption kinetics and thermodynamics of DMWCs on hydroquinone were comprehensively studied. The results showed that DMWCs, with a porous structure, consisting of quartz and crystalline graphite, achieved a removal rate and adsorption capacity of 76.8% and 12.31 mg/g, respectively, at a hydroquinone dosage of 200 mg and pH 7. The pseudo-second-order kinetic model provided a better fit for the adsorption process of hydroquinone, with a correlation coefficient (R2 = 0.99) higher than other models. The Freundlich equation, Redlich-Peterson equation, and Koble-Corrigan equation all fitted well with the adsorption isotherm data, with correlation coefficients (R2) higher than 0.93. The regeneration test demonstrated that DMWCs maintained an elimination rate of hydroquinone above 73% even after 11 times of reuse. This study presents DMWCs as an effective adsorbent for the removal of hydroquinone from wastewater.

Summary: In smart cities, target detection is a major issue to avoid traffic congestion, and it has wide applications in military, traffic, civilian, sports, etc. Unmanned aerial vehicles (UAVs) have become popular for target examination due to their mobility, low cost, wide field of view, and ease of use. However, the small size of objects in UAV images often leads to a deficient performance of actual recognition models. To address this, deep learning approaches have been proposed to improve accuracy and optimize design.

Summary: The effect of Al3+ substitution on the morphology of CM2A8, as a toughening material, has been investigated using theoretical calculation and experimental methods. The first-principle calculation showed that Al3+ preferentially substitutes for Mg2+ and decreases the formation energy of CM2A8, resulting in the synthesis of pure CM2A8 phase. Moreover, the surface energy of Al3+-substituted CM2A8 is reduced, promoting the growth of platelet CM2A8. Experimental studies confirmed that Al3+ substitution can enhance the phase purity of CM2A8 and transform its morphology from equiaxed to platelet. When the substitution amount of Al3+ reaches x=0.2 (CaMg2-3xAl16+2xVxO27), platelet CM2A8 grains with a proportion of 93.4% can be obtained.

Summary: In this study, the quantitative relationship between various factors and the oxidation resistance of Ni-based superalloys was established using machine learning. The importance of different alloying elements and their coupling effect were clarified and discussed. It was found that Ti, Cr, and Al are the most important elements affecting the oxidation resistance, while Mo and Nb have a detrimental effect. Novel Ni-based superalloys with better oxidation resistance than commercial alloys were screened out based on these findings. This work provides new ideas for accelerating the design of novel Ni-based superalloys with better comprehensive properties.

Summary: Surface passivation is an effective strategy to enhance the stability of halide perovskites. Formation and adsorption energies are commonly used to screen passivators. However, local surface structure is found to be a crucial factor for the stability of tin-based perovskites after surface passivation. The weakened Sn-I bond strength and the formation of surface iodine vacancy are responsible for the poor surface structure stability in tin-based perovskites.
