Article Abstract
Identifying all the possible Li sites in a crystal structure is the first step toward understanding the Li-ion migration in solid electrolytes for Li batteries. Here, we discover that the perovskite structure, a widely studied prototypic structure for solid electrolytes, may host Li ions in three different sites instead of only two sites as commonly believed. Thanks to integrated differential phase contrast (iDPC) scanning transmission electron microscopy (STEM), the Li ions that are too light to be detected in the conventional high-angle annular dark-field (HAADF) STEM are successfully visualized in the lattice. Combined with first-principles computations, this microscopy technique discloses the existence of Li ions in an interstitial site that has not been reported to host Li ions before in the perovskite structure and different Li-ion transport behaviors. This discovery enables a more comprehensive understanding of Li-ion transport in the perovskite structure.

Achieving UVA/B-selective, skin-inspired nociceptors with perception and blockade functions at the single-unit device level remains challenging. This is because the device necessitates distinct components for every performance metric, thereby leading to complex preparation processes and restricted performance, as well as the absence of deep UV (UVB and below)-selective semiconductors. Here, to address this, we develop a structure-simplification skin-inspired nociceptor using a reverse type-II CuAgSbI/MoS heterostructure.

Perovskite materials have revolutionized optoelectronics by virtue of their tunable bandgaps, exceptional optoelectronic properties, and structural flexibility. Notably, the state-of-the-art performance of perovskite solar cells has reached 27%, making perovskite materials a promising candidate for next-generation photovoltaic technology. Although numerous reviews regarding perovskite materials have been published, the existing reviews generally focus on individual material systems (e.

Perovskites have a large number of intrinsic defects and interface defects, which often lead to non-radiative recombination, and thus affect the efficiency of perovskite solar cells (PSCs). Introducing appropriate passivators between the perovskite layer and the transport layer for defect modification is crucial for improving the performance of PSCs. Herein, two positional isomers, 1-naphthylmethylammonium iodide (NMAI) and 2-naphthylmethylammonium iodide (NYAI) are designed.

Quantum-confined perovskites represent an emerging class of materials with great potential for optoelectronic applications. Specifically, zero-dimensional (0D) perovskites have garnered significant attention for their unique excitonic properties. However, achieving phase-pure, size-tunable 0D perovskite materials and gaining a clear understanding of their photophysical behavior remains challenging.

Circularly polarized luminescence (CPL) has emerged as a critical technology for anticounterfeiting and optical display applications due to its unique chiroptical properties. We report a multicolor CPL-emitting elastomeric film (P37/PSK@SiO-PDMS) that synergistically combines chiral helical polyacetylene (P37) and a surface-engineered perovskite (PSK@SiO) through hydrogen-bond-directed assembly. Confinement within the PDMS matrix drives P37 to self-assemble into a chiral supramolecular structure through hydrogen bonding, inducing a chiroptical inversion.
