Non-centrosymmetric material systems can generate spontaneous photocurrent without a p-n junction under uniform illumination, which is known as the bulk photovoltaic effect（BPVE）. It has garnered significant attention for its application potential in the fields of energy harvesting and photoelectric detection. In this study, we report the BPVE observed in twodimensional ferroelectric α-In2Se3multilayer flakes. The reversal in spontaneous photocurrent polarity is observed and associated with the out-of-plane ferroelectric polarization direction. The spontaneous photocurrent originating from the shift current is also polarization-sensitive. The amplitude of spontaneous photocurrent is further increased by one order of magnitude through vacuum annealing. Our results provide a further application potential for new-generation photodetectors based on BPVE with low power consumption and multi-dimensional optoelectronic detection.

Photoswitchable molecular assembly for controlled chloride transport across the lipid membranes

science China Chemistry 2025年

Inspired by nature, biomimetic photoregulated ion transporters have attracted great interest because of the spatial and temporal control over ion transport, in which photocontrollable anion transport remains a very challenging task. Herein, we demonstrate an anionophore AZC for photoregulating anion transport with a high selectivity for chloride over hydroxide across the lipid membranes. Our strategy is based on a well-designed bidentate iodo-triazole anion receptor equipped with an azobenzene moiety, which recognizes Cl-by C–I halogen bonding and C–H hydrogen bonding and switches its states in the lipid membranes from inactive aggregates to active single molecules through azobenzene photoisomerization, thereby achieving controllable Cl-transport. Compared with trans-AZC, cis-AZC exhibits much higher ion transport activity with an EC50（the effective concentration required for 50% activity） value at 28 nM, which is one of the highest reported activities to date for halogen bonding anionophores. Finally, it allows the modulation of Cl-transport upon reversible photoisomerization of AZC using alternative ultraviolet and visible light irradiation. This work provides a new strategy for designing stimuli-responsive anion transporters and paves the way for potential applications in remotely controlled membrane transport and treatment of related diseases.

Anisotropy characterization of upper shanghai clays: Shear strength and small-strain stiffness

Comprehensive investigations have been conducted to study the structure and overconsolidation of upper shanghai clays, i.e. Layers 2–6 clays, typically located at depths of 30–40 m. However, limited information is available on their anisotropy, and even less is known about the correlation between structure, overconsolidation, and anisotropy. In this study, the undrained anisotropy characteristics of shear strength and small-strain shear stiffness in upper shanghai Layers 2–6 clays were thoroughly assessed using a series of K0-consolidated undrained triaxial compression (TC) and triaxial extension (TE) tests (K0 is the coefficient of lateral earth pressure at rest). The effective stress paths, shear strength, and small-strain shear stiffness from the undrained TC and TE tests demonstrate the anisotropic behaviors in upper shanghai clays. Analyses of data from upper shanghai clays and other clays worldwide indicate that the shear strength anisotropy ratio (Ks) converges at 0.8 as the overconsolidation ratio (OCR) and plasticity index (Ip) increase, while the small-strain shear stiffness anisotropy ratio (Re) converges at 1.0. The influence of OCR on Ks and Re is more pronounced than that of Ip and sensitivity (St). Nevertheless, no clear correlation between Ks and Re is observed in upper shanghai clays.

Dimensional-noise-aware battery lifetime prediction via an EM-TLS framework

Progress in Natural science:Materials International 2025年第01期 146-155页

作者： Chenlong Yu Ting Lu Guohua Liu Xiaoang Zhai Wuyan Deng Jiayu Wan Yang Liu Xin Li School of Computer science and Technology Donghua University Future Battery Research Center Global Institute of Future Technology Shanghai Jiaotong University Data science Research Center Duke Kunshan University

Machine learning has been massively utilized to construct data-driven solutions for predicting the lifetime of rechargeable batteries in recent years, which project the physical measurements obtained during the early charging/discharging cycles to the remaining useful lifetime. While most existing techniques train the prediction model through minimizing the prediction error only, the errors associated with the physical measurements can also induce negative impact to the prediction accuracy. Although total-least-squares(TLS) regression has been applied to address this issue, it relies on the unrealistic assumption that the distributions of measurement errors on all input variables are equivalent, and cannot appropriately capture the practical characteristics of battery degradation. In order to tackle this challenge, this work intends to model the variations along different input dimensions, thereby improving the accuracy and robustness of battery lifetime prediction. In specific, we propose an innovative EM-TLS framework that enhances the TLS-based prediction to accommodate dimension-variate errors, while simultaneously investigating the distributions of them using expectation-maximization(EM). Experiments have been conducted to validate the proposed method based on the data of commercial Lithium-Ion batteries, where it reduces the prediction error by up to 29.9 % compared with conventional TLS. This demonstrates the immense potential of the proposed method for advancing the R&D of rechargeable batteries.
