Giant bulk photovoltaic effect driven by interfacial symmetry breaking in MoS 2 /Ta 2 NiSe 5 heterostructures
Abstract Van der Waals (vdW) heterostructures offer a versatile platform for engineering unconventional bulk photovoltaic (BPV) effect through interfacial symmetry breaking. However, the coexistence of multiple photophysical mechanisms, driven by structural complexity, spontaneous charge transfer, and strong interlayer coupling, often obscures the microscopic origin of the BPV response and hinders its rational optimization.
Semantic priors and virtual outlier synthesis enable parameter-efficient open-world object detection
Abstract Open-world object detection requires knowledge of categories and discovery of new objects never seen in training. Full model fine tuning fails often in such dynamic environment. Fully tuned models overfit known classes and lose their sensitivity to unknown objects at high computational cost. To solve this problem, we propose a Parameter-Efficient Open-World Object Detection (PE-OWOD) framework, a simple and light approach to retrain.
Acoustoelectric control of optoelectronic anisotropy for reconfigurable polarimetry
Abstract Harnessing light polarization provides a powerful degree of freedom for optical communications, imaging, and sensing. Two-dimensional (2D) anisotropic semiconductors have emerged as a promising platform for miniaturized on-chip polarimetry; however, their polarization responses remain constrained by intrinsic crystal symmetries and static device geometries, limiting functional tunability.

An Unprecedented Cu6 Cluster-Based Bimetallic MOF with Multiple Open Sites for High CO2 Capture and Efficient CO2 Conversion
An Unprecedented Cu6 Cluster-Based Bimetallic MOF with Multiple Open Sites for High CO2 Capture and Efficient CO2 Conversion Based on the soft-hard acid-base theory, a novel bimetallic MOF (JLU-MOF108) has been successfully syntheszied through one-pot synthesis method.
Highlights • hPSCs undergo severe apoptosis when differentiated together with mESCs • MYCN overcomes apoptosis of hPSCs in co-differentiation with mESCs • MYCN plus BCL2 largely enhance interspecies chimera efficiency of hPSCs • Obtaining functional human HPCs through enhanced interspecies chimerism with hPSCs Summary Obtaining functional human cells through interspecies chimerism with human pluripotent stem cells (hPSCs) remains unsuccessful due to its extremely low efficiency.

Supramolecular interactions induced distortion of BTB ligands: breaking convention to reproduce the unusual (3,4,4)-connected MOF topology
Supramolecular interactions induced distortion of BTB ligands: breaking convention to reproduce the unusual (3,4,4)-connected MOF topology An unusual (3,4,4)-connected MOF topology has been reproduced by 4,4’,4’’-benzene-1,3,5-triyl-tribenzoate (BTB) ligand which was previously judged not feasible to form. The outcome demonstrates that supramolecular interactions play a key role in the formation of this highly distorted network.
