Constructing van der Waals heterostructures (vdWHs) has emerged as an attractive strategy to combine and enhance the optoelectronic properties of stacked materials. Herein, by means of first-principles calculations, we investigate the geometric and electronic structures of the AlP/CsBiICl vdWH as well as its tunable band structure an external electric field. The AlP/CsBiICl vdWH is structurally and thermodynamically stable due to the low binding energy and the small energy fluctuation at room temperature.

Nonvolatile control of spin order or spin excitations offers a promising avenue for advancing spintronics; however, practical implementation remains challenging. In this Letter, we propose a general framework to realize electrical control of magnons in 2D magnetic insulators. We demonstrate that in bilayer ferromagnetic insulators with strong spin-layer coupling, the electric field can effectively manipulate the spin exchange interactions between the layers, enabling nonvolatile control of the corresponding magnons.

Hydrogen evolution reaction (HER), as one of the most advanced methods for the green production of hydrogen, is greatly impeded by inefficient mass transfer. Here we present an efficiently reactant enriched and mass traffic system by integrating high-curvature Pt nanocones with 3D porous TiAl framework to enhance mass transfer rate. Theoretical simulations, in situ Raman spectroscopy and potential-dependent Fourier transform infrared spectroscopy results disclose that the strong local electric field induced by high-curvature Pt can greatly promote the HO supply rate during HER, resulting in ∼1.

Background: Ambient ionization mass spectrometry (MS) has attracted significant attention due to its simplicity and ease of operation. Contactless, or field-induced, ionization is one of the ambient ionization techniques. In this approach, no direct electrical contact or additional voltage is required on the ionization-assisted substrate.

Photocatalytic CO reduction technology plays a significant role in the energy and environmental sectors, highlighting the necessity for developing high-efficiency and stable catalysts. In this study, a novel photocatalyst, xNiCoO/CN (x = 1, 3, and 5 wt%), was synthesized by depositing zeolitic imidazolate framework-67 (ZIF-67)-derived nickel cobaltate (NiCoO) hollow nanocages onto porous graphitic carbon nitride (g-CN, CN) nanosheets for photocatalytic CO reduction. Under visible light irradiation, the resulting 3NiCoO/CN photocatalyst demonstrated exceptional CO yields of up to 2879.
