Covalent linkages are the key component of covalent organic frameworks (COFs). The development stable and functional is essential to expand COFs family broaden their application prospects. In this work, we report synthesis crystalline chemical 4-carboxyl-quinoline linked (QL-COFs) via Doebner reactions in both one-pot (OP) post-synthetic modification (PSM) methods. Both methods can be universally applied most reported imine bottom-up construction or linkage conversion. Owing contractive pore...
The realization of quantum spin Hall effect in HgTe wells is considered a milestone the discovery topological insulators. Quantum states are predicted to allow current flow at edges an insulating bulk, as demonstrated various experiments. A key prediction yet be experimentally verified breakdown edge conduction under broken time-reversal symmetry. Here we first establish systematic framework for magnetic field dependence electrostatically gated devices. We then study inverted well device...
It is generally believed that the electron-withdrawing cyano group in olefin linkage would inhibit stability and π-conjugation of covalent organic frameworks (COFs), which raises concerns about their optoelectronic properties. However, structure–activity relationship between structure linkages properties COFs still inconclusive. In this work, imine-, vinylene-, acrylonitrile-linked with identical triphenyltriazine building blocks were designed synthesized. Our work demonstrated construction...
This paper presents the design and fabrication of batch-processed cantilever probes with electrical shielding for scanning microwave impedance microscopy. The diameter tip apex, which defines resolution, is less than 50 nm. width stripline thicknesses insulation dielectrics are optimized a small series resistance (<5 Ω) background capacitance (∼1 pF), both critical high sensitivity imaging on various samples. coaxial ensures that only probe interacts sample. structure designed to be...
Following the discovery of Higgs boson at LHC, new large colliders are being studied by international high-energy community to explore physics in detail and beyond Standard Model. In China, a two-stage circular collider project CEPC-SPPC is proposed, with first stage CEPC (Circular Electron Positron Collier, so-called factory) focused on physics, second SPPC (Super Proton-Proton Collider) This paper discusses this stage.
Atomic force microscope (AFM) has been defined as the one of most powerful instruments to explore micro/nanoworld in various fields. To lower imaging noise, AFMs are commonly equipped with open-loop nanopositioners (scanners). However, hysteretic effect AFM positioners is a dominate factor that increases position error during AFM-based manipulations. reduce hysteresis, inverse compensation approach an effective solution. Normally, compensator designed for manipulation task maximum working...
Combining different semiconductor materials to construct heterojunctions is a promising method achieve efficient photocatalysis; however, it still challenge accurately through molecular regulation. In this work, we take advantage of the remaining aldehyde groups in substoichiometric covalent organic framework (denoted as PTO-COF) precise construction covalently linked 2D/2D nanosheets (CONs) mechanochemical methods. The ultrathin structure CONs endowed them with superior photoinduced charge...
We proposed a strategy that benzothiazole-linked covalent organic framework (TTT-COF) was used as substrate to prepare metal composite photocatalyst Pd NPs@TTT-COF. Firstly, benzothiazole linked TTT-COF exhibited superior chemical stability and photoresponse. Moreover, finer particle size (2.01 nm) more uniform distribution of NPs were observed in NPs@TTT-COF owing the binding interaction between S groups. efficiency reusability photocatalytic C-C cross-coupling reactions. Mechanism study...
Abstract When blood vessels are injured, leader cells emerge in the endothelium to heal wound and restore vasculature integrity. The characteristics of during endothelial collective migration under diverse physiological conditions, however, poorly understood. Here we investigate regulation function by plasma lithography geometric confinement generated. Endothelial display an aggressive phenotype, connect follower via peripheral actin cables discontinuous adherens junctions, lead migrating...
The underlying principle of the unique dynamic adaptive adhesion capability a rock-climbing fish (Beaufortia kweichowensis) that can resist pull-off force 1000 times its weight while achieving simultaneous fast sliding (7.83 body lengths per second (BL/S)) remains mystery in literature. This adhesion-sliding ability has long been sought for underwater robots. However, strong surface and appear to contradict each other due need high contact stress. skillfully balanced mechanism tight is...
Collective cell behavior in response to mechanical injury is central various regenerative and pathological processes. Using a double-stranded locked nucleic acid probe for monitoring real-time intracellular gene expression, we examined the spatiotemporal of epithelial cells during injury-induced collective migration compared blocker assay with minimal as control. We showed that ∼150 μm from wound edge exhibit gradient injury, expressing different genes depending on wounding process. While...
The p-type silicon giant piezoresistive coefficient is measured in top-down fabricated nano-thickness single-crystalline-silicon strain-gauge resistors with a macro-cantilever bending experiment. For relatively thicker samples, the variation of terms thickness obeys reported 2D quantum confinement effect. ultra-thin however, deviates from quantum-effect prediction but increases value by at least one order magnitude (compared to conventional piezoresistance bulk silicon) and can change its...
Complex many-body interaction in perovskite manganites gives rise to a strong competition between ferromagnetic metallic and charge-ordered phases with nanoscale electronic inhomogeneity glassy behaviors. Investigating this state requires high-resolution imaging techniques sufficient sensitivity stability. Here, we present the results of near-field microwave microscope on strain-driven manganite film. The high contrast two electrically distinct allows direct visualization phase separation....

Systematic manipulation of a cell microenvironment with micro- and nanoscale resolution is often required for deciphering various cellular molecular phenomena. To address this requirement, we have developed plasma lithography technique to manipulate the by creating patterned surface feature sizes ranging from 100 nm millimeters. The goal be able study, in controlled way, behaviors individual cells as well groups their interactions. This method based on selective modification chemistry...
