Indirect Band Edge and Chain‐Locked Linear Dichroism in the Quasi‐1D Van der Waals Antiferromagnet AgCrP2S6

open access: yesAdvanced Functional Materials, EarlyView.
AgCrP2S6 reveals a momentum‐indirect band edge (≈1.35 eV) and chain‐locked linear dichroism: the first direct transitions emerge at 1.6–1.8 eV for E||a. Resonant Raman and photoemission corroborate this assignment. In ACPS/graphene heterostructures, photocurrent turns on above ≈1.5 eV and follows the same polarization selection rules (anisotropy ≈0.53),

Study on the Resonance Characteristics and Active Damping Suppression Strategies of Multi-Inverter Grid-Connected Systems Under Weak Grid Conditions

open access: yesEnergies
When a multi-inverter grid-connected system is influenced by the parasitic parameters of LCL-type inverters and the impedance of the connected system’s lines, its resonance characteristics become more complex and difficult to predict.

Biointerface Membranes Orchestrating Site‐Specific Osteoimmunomodulatory and Antibacterial Effects for Enhanced Osseous Regeneration in Periodontal Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Here, a biointerface membrane engineered with site‐specific interfacial properties is developed. During implantation between gingival and bone defect, the membrane creates a pro‐osteogenic microenvironment, precisely modulates cellular activities at each biointerface, and facilitates the orchestration of complex healing events, ultimately leading to ...
