The separator located between the positive and negative electrodes not only provides a lithium‐ion transmission channel but also prevents short circuits for direct contact of electrodes. The inferior dimension thermostability of commercial polyolefin separators intensifies the thermal runaway of batteries under abuse such as short circuits, overcharge, and so on. a polyvinylidene fluoride/polyether...
Transparent nano‐polycrystalline diamond (t‐NPD) possesses superior mechanical properties compared to single and traditional polycrystalline diamonds. However, the harsh synthetic conditions significantly limit its synthesis and applications. In this study, a synthesis routine is presented for t‐NPD under low pressure and low temperature conditions, 10 GPa, 1600 °C and 15 GPa, 1350 °C similar with...
Materials with various single‐transition metal atoms dispersed in nitrogenated carbons (M─N─C, M = Fe, Co, and Ni) are synthesized as cathodes to investigate the electrocatalytic behaviors focusing on their enhancement mechanism for performance of Li–S batteries. Results indicate that the order of both electrocatalytic activity and rate capacity for the M─N─C catalysts is Co > Ni > Fe, and the...
Precise structural control has attracted tremendous interest in pursuit of the tailoring of physical properties. Here, this work shows that through strong ligand‐mediated interfacial energy control, Au‐Cu2O dumbbell structures where both the Au nanorod (AuNR) and the partially encapsulating Cu2O domains are highly crystalline. The synthetic advance allows physical separation of the Au and Cu2O domains,...
The well‐defined 2D or 3D structure of covalent organic frameworks (COFs) makes it have great potential in photoelectric conversion and ions conduction fields. Herein, a new donor–accepter (D–A) COF material, named PyPz‐COF, constructed from electron donor 4,4′,4″,4′″‐(pyrene‐1,3,6,8‐tetrayl)tetraaniline and electron accepter 4,4′‐(pyrazine‐2,5‐diyl)dibenzaldehyde with an ordered and stable π‐conjugated...
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...
Crystal facet engineering has been recognized as a powerful strategy to finely modulate the charge separation behavior in semiconductor photocatalysis; however, disclosing the intrinsic roles that the morphologies and crystal facets play on photogenerated charge separation of semiconductor nanocrystals remains elusive. Herein, exemplified on the typical visible‐light‐responsive photocatalyst bismuth...
Exosomes, known as nanometer‐sized vesicles (30–200 nm), are secreted by many types of cells. Cancer‐derived exosomes have great potential to be biomarkers for early clinical diagnosis and evaluation of cancer therapeutic efficacy. Conventional detection methods are limited to low sensitivity and reproducibility. There are hundreds of papers published with different detection methods in recent years...
Danqing Liu, Chongshen Guo, Bin Yang, and co‐workers report the plasmonic enhanced ROS activation on low‐work‐function tungsten nitride for near infrared (NIR)‐driven photocatalysis (article number 2004557). In the cover image, the atomic structure is the most reactive facet of (110). The background is constructed with water bubbles, while red line is the incident NIR light and the golden balls are...
Realizing near‐infrared (NIR) driven photocatalytic reaction is one of the promising strategies to promote the solar energy utilization and photocatalytic efficiencies. However, effective reactive oxygen species (ROS) activation under NIR irradiation remains to be great challenge for nearly all previously reported photocatalysts. Herein, the cubic‐phase tungsten nitride (WN) with strong plasmonic...
Conventional pressure sensing devices are well developed for either indirect evaluation or internal measuring of fluid pressure over millimeter scale. Whereas, specialized pressure sensors that can directly work in various liquid environments at micrometer scale remain challenging and rarely explored, but are of great importance in many biomedical applications. Here, pressure sensor technology that...
