Covalent organic frameworks writ large framework (COF) materials have been difficult to characterize structurally and exploit because they tend form powders or amorphous materials. Ma et al. studied a variety of three-dimensional COFs based on imine linkages (see the Perspective by Navarro). They found that addition aniline inhibited nucleation allowed growth crystals enough for single-crystal x-ray diffraction studies. Evans describe two-step process in which nanoscale seeds boronate...
We report herein the first example of interpenetration isomerism in covalent organic frameworks (COFs). As a well-known three-dimensional (3D) COF, COF-300 was synthesized and characterized by Yaghi group 2009 as 5-fold interpenetrated diamond structure (dia-c5 topology). found that adding an aging process prior to reported synthetic procedure afforded formation isomer, dia-c7 COF-300. The 7-fold this new isomer identified powder X-ray diffraction rotation electron analyses. Furthermore, we...
Crystal size effect is of vital importance in materials science by exerting significant influence on various properties and furthermore their functions. covalent organic frameworks (COFs) has never been reported because controllable synthesis difficult, despite promising have exhibited many aspects. Here, we report the diverse crystal effects two representative COFs based successful realization crystal-size-controlled synthesis. For LZU-111 with rigid spiral channels, reflects pore surface...
Growth of covalent organic frameworks (COFs) as single crystals is extremely challenging. Inaccessibility open-structured single-crystal COFs prevents the exploration structure-oriented applications. Herein we report for first time a non-interpenetrated COF, LZU-306, which possesses open structure constructed exclusively via assembly. With high void volume 80 %, LZU-306 was applied to investigate intrinsic dynamics reticulated tetraphenylethylene (TPE) individual aggregation-induced-emission...
Quantitative description of the complex relationship between rolling process and microstructure is crucial for improving performance 2205 duplex stainless steel products. In this work, four distinct processes were used three passes hot steel. The study delved into macroscopic morphology, microstructural gradients, texture evolution sheets in various states. addition, a data expansion method was to expand original experimental data, support vector machine model optimized by genetic algorithm...
Pharmacological, spectrophotographic and laser scanning confocal microscopy (LSCM) approaches were used to investigate the roles of hydrogen sulfide (H2S) peroxide (H2O2) played in signaling transduction stomatal closure induced by CdCl2 Vigna radiata L. In present study, could induce a dose- time-dependent manner, which was inhibited H2S modulators hypotaurine (HT), aminooxy acetic acid (AOA), hydroxylamine (NH2OH), potassium pyruvate (C3H3KO3), ammonia (NH3), H2O2 ascorbic (ASA), catalase...
Abstract Growth of covalent organic frameworks (COFs) as single crystals is extremely challenging. Inaccessibility open‐structured single‐crystal COFs prevents the exploration structure‐oriented applications. Herein we report for first time a non‐interpenetrated COF, LZU‐306, which possesses open structure constructed exclusively via assembly. With high void volume 80 %, LZU‐306 was applied to investigate intrinsic dynamics reticulated tetraphenylethylene (TPE) individual...
TP321 stainless steel is widely used in hydrogenation refining pipes owing to its excellent performance of creep stress resistance and high-temperature resistance. In this study, thermal simulation tests were carried out on the welding heat-affected zone (HAZ) at temperatures 1300 °C, 1100 850°C using a Gleeble 3800 testing machine. Slow strain tensile conducted under condition electrolytic hydrogen charging (EHC) metallographic microstructure cracks as well morphology fractures analyzed...
Laparoscopic cholecystectomy (LC) has rapidly become the procedure of choice for management patients with gall-bladder stones. This contrasts who have common bile duct and intrahepatic stones still usually need an open operation. On basis experience a number LC by one surgeon animal experiments, we completed laparoscopic exploration both intra- extrahepatic ducts T-tube drainage 57 calculi over 13 months during 1992-1993 satisfactory results. The average operating time was 150 min, range 100...
The effects of plastic deformation on the microstructure evolution grade X100 pipeline were investigated by SEM, TEM and EBSD tests. result shows that quasipolygon ferrite deforms firstly under strain initial stage, then both acicular granular bainite change remarkably with value increase. When tension stress reaches tensile strength, microcracks nucleate around inclusion M/A constitute, expand increases, finally cracks connection causes crack penetration until expiration. Furthermore,...
It is well-known that a multilinear system with nonsingular M-tensor and positive right-hand side has unique solution. Tensor splitting methods generalizing the classical iterative for linear systems have been proposed finding The Alternating Anderson-Richardson (AAR) method an effective to accelerate methods. In this study, we apply idea of AAR solution quickly. We first present tensor Richardson based on regular splittings, then Anderson acceleration derive method, finally, periodically...
