Abstract The dangling‐bond‐free surfaces of 2D materials enable them to possess various degrees freedom form heterostructures with non‐2D materials. This allows for the combination advantages different dimensional fabricate van der Waals (vdW) heterostructures, thereby improving device performance and even bringing diversity novelty. Herein, a mixed‐dimensional vdW heterostructure photodiode comprising 1D tellurium (Te) nanowire molybdenum ditelluride (MoTe 2 ) flake is demonstrated. Forward...
Abstract Perovskite solar cells (PSCs) have demonstrated a high power conversion efficiency, however, the large energy loss due to non‐radiative recombination is main challenge for further performance enhancement. Here, surface treatment strategy developed by heat‐induced decomposition of thin interlayer 2,7‐Naphthaleneditriflate (NAP) in situ reconstruct perovskite energetics. It verified that reconstructed energetics match better with upper hole transport layer compared intrinsic...

Herein, controllable photocurrent generation enhanced performances...
Groundwater is crucial for domestic, agricultural, and ecological uses, particularly in the lower reaches of arid basins, where its quality often limits availability. A total 26 phreatic groundwater samples were collected from a typical endorheic watershed on Tibetan Plateau to assess hydrochemical characteristics inland watersheds. The characteristics, quality, formation mechanisms analyzed using Entropy-Weight Water Quality Index (EWQI), irrigation water indexes (such as sodium adsorption...

Abstract In recent years, researchers have explored the interlayer stacking structure of bilayer (BL) transition metal dichalcogenides (TMDCs) and found that it has unique impact on electrical, optical, vibrational properties TMDCs. Unfortunately, size BL TMDCs synthesized by pre-existing methods is not large. addition, there any effective mean to control number layers as well stack structure. This major limiting factor for further exploration We report a new method rapid controllable growth...
To investigate the effect of template removal methods on structure, properties and catalytic performance MCM-22 zeolite, dielectric-barrier discharge (DBD) plasma treatment thermal calcination have been comparatively studied for hexamethyleneimine (HMI) from two-dimensional layered precursor (MCM-22(P)).
