Potassium-ion batteries are a promising alternative to lithium-ion batteries. However, it is challenging achieve fast charging/discharging and long cycle life with the current electrode materials because of sluggish potassiation kinetics. Here we report soft carbon anode, namely highly nitrogen-doped nanofibers, superior rate capability cyclability. The anode delivers reversible capacities 248 mAh g-1 at 25 mA 101 20 A g-1, retains 146 2 after 4000 cycles. Surface-dominated K-storage...
Abstract Covalent organic frameworks (COFs) are distinguished from other polymers by their crystallinity 1–3 , but it remains challenging to obtain robust, highly crystalline COFs because the framework-forming reactions poorly reversible 4,5 . More chemistry can improve 6–9 this typically yields with poor physicochemical stability and limited application scope 5 Here we report a general scalable protocol prepare imine COFs, based on an unexpected framework reconstruction. In contrast...
Abstract Here we report a two-step, hierarchical synthesis that assembles trigonal prismatic organic cage into more symmetric, higher-order tetrahedral cage, or ‘cage of cages’. Both the preformed [2+3] building blocks and resultant [4[2+3]+6]cage molecule are constructed using ether bridges. This strategy affords excellent hydrolytic stability is not feature common dynamic linkers, such as imines. Despite its relatively high molar mass (3,001 g mol −1 ), exhibits good solubility...
There has been great interest in the use of porous polymers to remove organic dyes because their adjustable surface area and task-specific functionality. We chose a triptycene-based polymer ensure high porosity, introduced crown ether into sketch copolymer significantly enhance affinity for dye molecules. Novel copolymers triptycene crown-ether-15 (POP-TCE-15) were obtained by simple Friedel-Crafts reaction, highly effective removing from aqueous solution. POP-TCE-15 exhibited best...
Wildlife behavior can be influenced by the deployment of sensory cues in a landscape, but different vary strength and duration their effectiveness. We aimed to identify most effective cost-efficient countermeasures (sensory cues) deter wild boar (Sus scrofa) entry damage cornfields Hunchun, Jilin Province, China. These have experienced severe boars during critical 30-day period when this crop was ripening. From 2016 2021, were applied sequentially seeking control using either (1) visual...
Predicting the permeate flux is critical for evaluating and optimizing performance of forward osmosis (FO) process. However, solution diffusion models have poor applicability in accessing FO Recently, data-driven eXtreme Gradient Boosting (XGBoost) algorithm has been proven to be effective processing structure data engineering problems not utilized assess Herein, a combination XGBoost model with genetic (GA) was first proposed predict flux, highlighting its superiority process through...
Directly linked porphyrin dimers have attracted considerable attention because of their intriguing electronic features. Most emphasis has been placed on either with large dihedral angles between the constituent planar monomeric subunits or those overall planarity, referred to as "Planar-Twisted-Planar" and "Planar-Planar-Planar", respectively. Herein, we report a "Twisted-Planar-Twisted" framework, hexaphyrin dimer D that exists in trans configuration. Treatment MeOH affords two isomeric...
CoFe2O4 nanoparticles with different morphologies were successfully synthesized by co-precipitation method, followed heat treatment. XRD patterns showed that a single phase ferrite was obtained. By the method of heating, effect on morphology and properties is studied. The synthesis conditions (oxidation process temperature) dominated formation crystals morphologies. oxidation growth mechanisms behind nanocrystals investigated. saturation magnetization samples lower than bulk value, which...
In this work, halogen bonding interactions in the complexes of two new nitroxide radicals, which contain both a halogen-bond-donor group and an electron-spin-resonance-active radical unit, were investigated using density functional theory calculations. For comparison, corresponding hydrogen-bonded also examined. Halogen bonds these systems are predicted to be linear much stronger than hydrogen bonds. To further understand nature interactions, many theoretical methods, such as atoms...
First-principles simulations reveal atomistic mechanisms for adsorption and migration of lithium potassium on nitrogen-doped carbon nanotubes.
Abstract Organic compounds that can respond to external stimuli and exhibit fluorescence changes have drawn increasing attention recently because of their potential applications in intelligent displays, optical data storage, anticounterfeiting, bioimaging, sensors. Herein, we synthesized two new organic based on frameworks anthracene pyridine groups: 4‐(anthracen‐9‐yl) (AN9P) 4‐(anthracen‐2‐yl) (AN2P). Both compounds, solution solid state, including polycrystals single crystals, display...
The chiral charge density wave material (TaSe${}_{4}$)${}_{2}$I contains a half-filled Ta $d$-orbital, which creates Weyl points in metallic band structure. However, historical measurements show insulating electrical transport. authors use single-crystal diffraction and transmission electron microscopy to that large single crystals have pristine chirality: they can exhibit enantiomer over millimeters. They resolve the contradiction transport by showing consistent iodine deficiency of more...
Coupling Weyl quasiparticles and charge density waves (CDWs) can lead to fascinating band renormalization many-body effects beyond folding Peierls gaps. For the quasi-one-dimensional chiral compound (TaSe4)2I with an incommensurate CDW transition at TC = 263 K, photoemission mappings thus far are intriguing due suppressed emission near Fermi level. Models for this unconventional behavior include axion insulator phases, correlation pseudogaps, polaron subbands, bipolaron bound states, etc....
Abstract Metal dithiolene complexes have been extensively used for the elaboration of conducting or magnetic materials, whose molecular arrangements can be sensitively influenced by strong and directional noncovalent interactions. In this work, halogen bonds between N ‐methyl‐3‐halopyridinium cations cyano‐substituted anion radicals, [M(C 2 S ) CN] −• (M = Ni, Pd, Pt), were systematically investigated at M06 level theory. The CN···X interactions in these systems are predicted to considerably...
The quasi-one-dimensional chiral charge density wave (CDW) material (TaSe$_4$)$_2$I has been recently predicted to host Kramers-Weyl (KW) fermions which should exist in the vicinity of high symmetry points Brillouin zone materials with strong spin-orbit coupling. However, direct spectroscopic evidence KW is limited. Here we use helicity-dependent laser-based angle resolved photoemission spectroscopy (ARPES) conjunction tight-binding and first-principles calculations identify (TaSe$_4$)$_2$I....
