Membranes of sub-2-nanometer channels show high ion transport rates, but it remains a great challenge to design such membranes with desirable selectivities for separation applications. Here, covalent organic framework (COF) channel size ≈1.4 nm and abundant hydrogen bonding sites, exhibiting efficient sieving properties are demonstrated. The COF have monovalent cation permeation rates 0.1-0.2 mol m-2 h-1 extremely low multivalent permeabilities, leading over divalent K+ /Mg2+ ≈765, Na+ ≈680,...
Membranes of high ion permselectivity are significant for the separation species at subnanometer scale. Here, we report porous organic cage (i.e., CC3) membranes with hierarchical channels including discrete internal cavities and cage-aligned external connected by subnanometer-sized windows. The windows CC3 sieve monovalent ions from divalent ones dual nanometer-sized provide pathways fast transport a flux 1.0 mol m-2 h-1 mono-/divalent selectivity (e.g., K+/Mg2+) up to 103, several orders...
Fast transport of monovalent ions is imperative in selective ion separation based on membranes. Here, we report the situ growth crown ether@UiO-66 membranes at a mild condition, where dibenzo-18-crown-6 (DB18C6) or dibenzo-15-crown-5 perfectly confined UiO-66 cavity. Crown exhibit enhanced rates and mono-/divalent selectivity, due to combination size sieving interaction screening effects toward complete dehydration. Specifically, DB18C6@UiO-66 membrane shows permeation rate (e.g., K
Novel hierarchical porous carbon nanosheets (HPCS) with quantities of micropores and mesopores were prepared on a large-scale by using thermoplastic phenolic formaldehyde resin as the source copper nitrate template precursor. The HPCS, possessing thickness about 40 nm width several microns, exhibited high specific capacity favorable high-rate performance when used an anode material for lithium ion batteries (LIBs). reversible capacities 748 mA h g−1 at current density 20 460 even 1 A g−1,...
Iron sulfide-embedded carbon microspheres were prepared via a solvothermal process and show high specific capacity excellent high-rate performance as anode material for lithium-ion batteries.
Abstract Metal–organic frameworks (MOFs) with angstrom-sized pores are promising functional nanomaterials for the fabrication of cation permselective membranes (MOF-CPMs). However, only a few research reports show successful preparation MOF-CPMs good separation performance due to several inherent problems in MOFs, such as arduous self-assembly, poor water resistance, and tedious strategies. Besides, low permeation flux absence assisting functionalities MOFs is another big issue, which limits...
Driven by the evolution of electronic packaging technology for high-dense integration high-power, high-frequency, and multi-function devices in modern electronics, thermal management materials have become a crucial component guaranteeing stable reliable operation devices. Because its admirable in-plane conductivity, graphene is considered as desired conductor. However, promise films has been greatly weakened existence grain boundaries lead to high extent phonon scattering. Here, stitching...
Heat dissipation efficiency and electromagnetic interference (EMI) shielding performance are vital to integration, miniaturization, application of electronic devices. Flexible designable polymer-based composites promising candidates but suffer from unavoidable interfacial thermal resistances, anisotropic conductivity, low EMI limiting application. Herein, multifunctional epoxy resin (EP)-based with an interconnected carbon fibers (CFs) network structure containing a resistance were prepared...

Novel carbon nanotubes (CNTs) were prepared on a large-scale. Their morphology and structure characterized by scanning electron microscopy, transmission X-ray diffraction, Raman measurements. It was found that the CNTs possess quadrangular cross section, as well one open end "herringbone"-like walls, so these novel named q-CNTs. The unique of q-CNTs implies broad potential applications in many fields, including drug delivery, conductive high-strength composites, field emission displays...
In most of the reports, ball-milling graphitic materials would lead to decrease their crystal degree and further amorphization. However, large enhancement carbon black graphitized induced by ball milling were herein observed. The hollow structure remained without collapse. But from high resolution transmission electron microscopy, morphology each nanoparticle is changed polyhedron sphere after a certain time ball-milling. Accordingly, transformation model was proposed.
