Summary: In this study, a direct physics-informed neural network (DPINN) is proposed to analyze the stability of truss structures without the use of incremental-iterative algorithms. A neural network is used to minimize a loss function based on structural instability information.

Summary: Triboelectrification between metals, polymers, and semiconductors was investigated, revealing a universal mechanism involving both electrostatic induction and dynamic junction modulation. The outputs of triboelectrification exhibited four current/voltage peaks, two of which were attributed to electrostatic induction effects and determined by surface state densities and electron affinity differences between the materials. The other two peaks were associated with dynamic junction modulation effects and determined by charging exchange between surface states and depletion regions. While metals and polymers showed no modulation of depletion regions, only the peaks induced by electrostatic induction were observable. Semiconductors, on the other hand, exhibited additional peaks induced by junction modulation when in contact with any material type. These findings provide valuable insights for developing high-performance triboelectric nanogenerators.

Summary: Microplastics, sub-millimeter-sized plastic fragments, have been extensively found in the environment as relatively new pollutants that are difficult to degrade. They have irreversible adverse effects on microorganisms, animals, plants, and human health through the food chain. However, traditional detection and identification methods face challenges due to the small size, variety, and different properties of microplastics. This study presents a method using a liquid-solid triboelectric nanogenerator (LS-TENG) combined with a deep learning model to detect and classify microplastics in liquids. Experimental results demonstrate that the type and content of microplastics in the liquid significantly affect the contact electrification between the liquid and the perfluoroethylene-propylene copolymer. The LS-TENG sensor can quantitatively detect the content of microplastics and a convolutional neural network achieves high recognition accuracy in identifying different types of microplastics labels. This has great significance in expanding the application prospect of LS-TENG and realizing the detection of microplastics in liquids.

Summary: A physics-informed neural network (PINN) for digital materials analysis is introduced, trained without ground truth data using minimum energy criteria. The model reached similar accuracy as supervised ML models and prevented erroneous deformation gradients with hinge loss on the Jacobian. Parallel computing on GPU for strain energy calculation showed linear scalability with the number of nodes, laying the foundation for label-free learning in designing next-generation composites.
