The perovskite solar cells (PSCs) have achieved great success in power conversion efficiency due to their excellent optoelectrical properties of perovskite. However, the instability of PSCs severely impedes their commercialization. Recently, in situ cross‐linking strategy has been proposed to mitigate stability issues of PSCs, enabling highly efficient and stable PSCs. Here, the critical factors that...
Scaling up the chemical vapor deposition (CVD) of monolayer transition metal dichalcogenides (TMDCs) is in high demand for practical applications. However, for CVD‐grown TMDCs on a large scale, there are many existing factors that result in their poor uniformity. In particular, gas flow, which usually leads to inhomogeneous distributions of precursor concentrations, has yet to be well controlled....
Perforated Carbon Nanotube Films
In article number 2300766, Run Shi, Kai Liu, and co‐workers report a large‐scale growth of uniform monolayer MoS2 by evenly distributing gas flows of precursors through a perforated carbon nanotube film. The as‐grown monolayer MoS2 shows quite good uniformity in geometry, density, structure, and electrical properties.
Although noble metal nanocrystals have been studied extensively in the past decades, the shape‐controlled synthesis of non‐noble metal nanocrystals has remained challenging with limited success, which is a grand obstacle to their wide applications. Herein, a novel lattice mismatch–involved shape‐control mechanism of Cu nanocrystals in a seed‐mediated synthesis is reported, which can produce Cu nanoplates...
Synergistic therapy for malignant tumors has been developed in the past. However, several disadvantages that are associated with the applied inorganic nanoagents cannot be avoided, including intrinsic systemic toxicity, immunosuppression, and low therapeutic efficiency. Herein, a biocompatible, multifunctional, inorganic nanoagent that simultaneously integrates chemodynamic, starvation, and photothermal...
Alzheimer disease (AD) is the leading cause of dementia that affects millions of old people. Despite significant advances in the understanding of AD pathobiology, no disease modifying treatment is available. MicroRNA‐124 (miR‐124) is the most abundant miRNA in the normal brain with great potency to ameliorate AD‐like pathology, while it is deficient in AD brain. Herein, the authors develop a DNA nanoflowers...
Recently, lipid nanoparticles (LNPs) have attracted attention due to their emergent use for COVID‐19 mRNA vaccines. The success of LNPs can be attributed to ionizable lipids, which enable functional intracellular delivery. Previously, the authors established an automated high‐throughput platform to screen ionizable lipids and identified that the LNPs generated using this automated technique show comparable...
Artificial intelligence vision systems (AIVSs) with information sensing, processing, and storage functions are increasingly gaining attention in the science and technology community. Although synapse phototransistor (SPT) is one of the essential components in AIVSs, solution‐processed large‐area photonic synapses that can detect and recognize multi‐wavelength light are highly desirable. One of the...
Nanostructured gold has attracted significant interest from materials science, chemistry, optics and photonics, and biology due to their extraordinary potential for manipulating visible and near‐infrared light through the excitation of plasmon resonances. However, gold nanostructures are rarely measured experimentally in their plasmonic properties and hardly used for high‐temperature applications...
Co‐precipitation is generally refers to the co‐precipitation of two solids and is widely used to prepare active‐loaded nanoparticles. Here, it is demonstrated that liquid and solid can precipitate simultaneously to produce hierarchical core–shell nanocapsules that encapsulate an oil core in a polymer shell. During the co‐precipitation process, the polymer preferentially deposits at the oil/water interface,...
Here, a pair of A1–D–A2–D–A1 unfused ring core‐based nonfullerene small molecule acceptors (NF‐SMAs), BO2FIDT‐4Cl and BT2FIDT‐4Cl is synthesized, which possess the same terminals (A1) and indacenodithiophene unit (D), coupling with different fluorinated electron‐deficient central unit (difluorobenzoxadiazole or difluorobenzothiadiazole) (A2). BT2FIDT‐4Cl exhibits a slightly smaller optical bandgap...
Lightweight and mechanically strong protein fibers are promising for many technical applications. Despite the widespread investigation of biological fibers based on spider silk and silkworm proteins, it remains a challenge to develop low‐cost proteins and convenient spinning technology for the fabrication of robust biological fibers. Since there are plenty of widely available proteins in nature, it...
Over the last decades, water‐based lyotropic liquid crystals of nucleic acids have been extensively investigated because of their important role in biology. Alongside, solvent‐free thermotropic liquid crystals (TLCs) from DNA are gaining great interest, owing to their relevance to DNA‐inspired optoelectronic applications. Up to now, however, only the smectic phase of DNA TLCs has been reported. The...
Biomimetic delivery carriers using polypeptide/heparin hybrid nanoparticles that are adsorbed onto red blood cells for extended blood circulation time have been developed. This might open up an avenue to promote the innovations and advances of biomimetic, stimuli‐responsive drug delivery, especially for the site‐specific treatment of intravascular diseases such as thrombosis.
The formation of ultralong peptide crystalline nanobelts using a solvothermal approach from a di‐phenylalanine gel within 10 min, where the self‐assembly process is accelerated by several orders of magnitude compared with the month‐long glutaraldehyde induction method previously reported, has been demonstrated. The solvothermal treatment can facilitate the phase separation of di‐phenylalanine gels...
