Summary: Enhancements of both conductive and dielectric properties were observed under UV illumination using a ferroelectric absorber, potassium tantalate niobate (KTa1-xNbxO3, KTN). The UV-generated electron-hole pairs weakened the intrinsic ferroelectric polarization while enhancing the conductive property. The UV-induced heat effect caused the enhancement of the dielectric property, as confirmed by maximal rectification ratio showing opposite trends between direct heating and UV illumination processes.

Summary: Constructing conductive filler networks with high efficiency is essential for fabricating functional polymer composites. In this study, the researchers utilize the unrecognized geometric curvature of 2D sheets to break the efficiency limit of filler systems. They introduce the concept of hyperbolic curvature to mediate the incompatibility between 2D planar topology and 3D filler space, resulting in a highly efficient conductive path. The hyperbolic graphene framework demonstrates exceptional electrical and thermal conductive functions in nanocomposites. The study provides a solution to reconcile the incompatibility between 2D planar structure and 3D conductive path, presenting a geometrically optimal filler system for multifunctional nanocomposites and expanding the design possibilities of 2D sheets.

Summary: Extensive machine learning methods have brought about significant changes in various fields such as metals, catalysts, and polymers. However, the application of machine learning in the exploration of functional polymer-based composites, particularly in flame retardancy, is still in its early stages. In this study, an adaptive framework combining domain knowledge and machine learning was proposed to accelerate the optimization of high flame retardant composites. Different data resources, including experiments, handbooks, and published papers, were used for training, feedback, or prediction purposes. The framework demonstrated an effective approach for feature engineering and classification of flame-retardant polymer-based composites. Four machine learning methods were compared in the framework, and the combination of Lasso, Ridge, and ANN showed higher accuracy in predicting the limit oxygen index (LOI), assisting in the discovery of new experiments and effective prediction of different flame retardants. The optimized models from the adaptive framework could contribute to machine intelligence in the engineering of flame-retardant polymer-based composites. Moreover, the proposed adaptive framework has the potential to be extended to the machine intelligence design of other functional polymer-based composites.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
