Multilayers comprising alternating soft and hard layers offer enhanced toughness compared to all-hard structures. Here authors reveal how the hard and soft components in Ruddlesden–Popper perovskites work cooperatively to resist deformation under p

The surface octahedral tilt in exfoliated 2D perovskites is directly visualized by STM and the degree of the tilt varies with the number of layers of inorganic slabs and result in different amounts of excitonic red shift in photoluminescence.

Two nonlinear optical crystals, BaVO(IO3)5 and BaTaO(IO3)5, are designed by substituting Nb with V and Ta, respectively, in BaNbO(IO3)5, which is itself a recently synthesized infrared nonlinear optical (NLO) material. The designs of BaVO(IO3)5 and B

Lead-free tin-based perovskites are highly appealing for the next generation of solar cells due to their intriguing optoelectronic properties. However, the tendency of Sn2+ oxidation to Sn4+ in the tin-based perovskites induces serious film degradati

Existence of van der Waals gaps renders two-dimensional (2D) materials ideal passages of lithium for being used as anode materials. However, the requirement of good conductivity significantly limits the choice of 2D candidates. So far only graphite i

Polyethylene oxide (PEO)-based electrolytes have obvious merits such as strong ability to dissolve salts (e.g., LiTFSI) and high flexibility, but their applications in solid-state batteries is hindered by the low ion conductance and poor mechanical a
