Solution‐processed photodetectors have emerged as promising candidates for next‐generation of visible‐near infrared (vis–NIR) photodetectors. This is attributed to their ease of processing, compatibility with flexible substrates, and the ability to tune their detection properties by integrating complementary photoresponsive semiconductors. However, the limited performance continues to hinder their...

Emergent fermions arising from the excess electrons of electrides provide a new perspective for exploring semimetal states with unique Fermi surface geometries. In this study, a class of unique two‐dimensional (2D) highly anisotropic Dirac fermions is designed using a sandwich structure. Based on the structural design and first‐principles calculations, 2D electride MB (M = Ca/Sr, B = Cl/Br/I) is an...
Anode materials with high‐rate performances and good electrochemical stabilities are urgently required for the grid‐scale application of lithium‐ion batteries (LIBs). Theoretically, transition metal borides are desirable candidates because of their appropriate working potentials and good conductivities. However, the reported metal borides exhibit poor performances owing to their lack of favorable...

Recently, nonmetal NH4+ ions have attracted extensive attention for use as charge carries in the field of energy storage due to their abundant resources, environmental friendliness, and low cost. However, the development of aqueous ammonium‐ion batteries (AAIBs) is constrained by the absence of high‐voltage and long‐life materials. Herein, different tunnel‐structure MnO2 materials (α‐, β‐, and γ‐MnO...
Metal–organic frameworks (MOFs), as a subclass of porous crystalline materials with unique structures and multifunctional properties, play a pivotal role in various research domains. In recent years, significant attention has been directed toward composite materials based on MOFs, particularly MOF‐on‐MOF heterostructures. Compared to individual MOF materials, MOF‐on‐MOF structures harness the distinctive...

The exposure of active edge sites of transition metal dichalcogenide (TMD) in TMD‐based heterostructures is essential to enhance the catalytic activity toward electrochemical catalytic hydrogen evolution (HER). The construction of TMD‐based edge‐epitaxial heterostructures can maximally expose the active edge sites. However, owing to the 2D crystal structures, it remains a great challenge to vertically...
The selective quantification of copper ions (Cu2+) in biosamples holds great importance for disease diagnosis, treatment, and prognosis since the Cu2+ level is closely associated with the physiological state of the human body. While it remains a long‐term challenge due to the extremely low level of free Cu2+ and the potential interference by the complex matrices. Here, a pore‐engineered hydrogen‐bonded...
DNA origami synthesis is a well‐established technique with wide‐ranging applications. In most cases, the synthesized origami must be purified to remove excess materials such as DNA oligos and other functional molecules.
