A metal-organic nanotube (MONT) was synthesized by linking up the bent organic ligands and tetra-coordinated zinc cations under mild conditions. Structural analysis revealed that MONT has a very large exterior wall diameter of 4.91 nm an interior channel 3.32 nm. Interlocking nanotubes gives rise to 3D chiral framework containing 1D helical cylindered channels with 2.0 The interesting property synergizing functionality nanotubes, frameworks (MOFs), N-heterocyclic carbenes (NHCs). dye...
The reaction of 5,10,15,20-tetra(carboxyphenyl)porphyrin (H6TCPP) or metalated M-H4TCPP (M = CoII, NiII, CuII and VIVO) with lead nitrate afforded five metal–organic frameworks (MOFs), [Pb2(H2TCPP)]·4DMF·H2O (1), Pb2(Co–TCPP)(H2O)(DMF)]·1.5DMF (2), [Pb2(Ni–TCPP)(DMF)(H2O)]·1.5DMF·2H2O (3), [Pb2(Cu–TCPP)(DMF)(H2O)]·1.5DMF·2H2O (4) [Pb2(VO–TCPP)(H2O)2]·4DMF (5). Single crystal X-ray diffraction analysis revealed that the MOFs based on TCPP scaffolds differ in framework topologies porphyrin...
Since the weight of overburden is sustained by both backfill body and unmined solid coal in mining with compacted backfilling (CMCB) panels, stress deformation characteristics surrounding rocks are radically changed. The movement control mechanism coordinating shield CMCB was studied systematically this paper. Based on analysis deformational structural rock methods theoretical analysis, numerical simulation engineering test employed. results show that fracture main roof mainly controlled...
Reaction of 4,4′,4″-{[(2,4,6-trimethylbenzene-1,3,5-triyl)tris(methylene)]tris(oxy)}tribenzoic acid (H3TCM) with Mn2+, Cu2+, and Co2+ salts afforded four interesting metal–organic frameworks (MOFs), [Mn2(TCM)Cl(H2O)3]·3DMF·3CH3OH (1), [Mn4(TCM)2(CH3COO)2(DMF)5]·4CH3OH (2), [Cu2(TCM)(CH3COO)(DMF)(H2O)]·2DMF·3CH3OH (3) [Co3(TCM)2(H2O)5]·5DMF·3CH3OH (4). Single crystal X-ray diffraction analysis revealed that the structures based on flexible TCM tripod consist honeycomb lattices different...
The microstructure and mineral composition of the gangue play a decisive role in precipitation heavy metal elements. In this study, microstructure, composition, elements coal with different weathering degrees were analyzed through electron microscopy, X-ray diffraction, static immersion leaching experiments. following results derived. (1) After gangue, its compactness integrity changed significantly. structure transformed from relatively dense to loose, development large pores fractures...
In solid backfill coal mining (SBCM), loose gangue material (LGBM) is used to the goaf after resources are exploited from underground mines. Under certain geological conditions, LGBM with a height may be soaked in water, and then becomes saturated, significantly altering its mechanical properties. The confined compression experiments were this paper analyze deformation crushing characteristics of varying water heights results showed that large number small holes distributed blocks main...
An effective strategy to immobilize both zwitterion and POM moieties into porous hybrid materials was developed. These demonstrate remarkable efficiency for selective scavenging photolysis of cationic dyes from polluted water.
Two flexible zwitterionic ligands of HL11 and HL22 derived from N-heteroaromatic molecules were used to construct five coordination polymers [CdL11(H2O)2]·NO3·5H2O (1), [Zn(L11)2(H2O)4]·5H2O (2), [CdL11Cl] (3), [Zn(L22)2]·2H2O (4) [Cd(L22)2] (5) by reaction with corresponding metal salts. In these compounds, L11 L22 link up nodes form distinct lamellar or linear networks. Compounds 1 4 crystallize in chiral space groups, which are second-order non-linear optical (NLO) active induced the...
The reaction of 1,4,5,8-naphthalene-tetracarboxylic dianhydride and NiCl2·6H2O in a mixed solvent pyridine water afforded green crystals [Ni2L(Py)4(H2O)6]·Py·10H2O (L = 1,4,5,8-naphthalene-tetracarboxylate; Py pyridine; 1), which consists centrosymmetric related nickel(II) binuclear units, lattice molecules. molecules hydrogen bond into tape network comprising tetrameric clusters pentameric as subunits. tapes are further linked by hexameric to form sheet, is staked 3D supramolecular...
Even though solid backfi ll mining can address some environmental issues of coal (like surface subsidence and gangue storage), on the other hand long exposure to rain or surfi cial water will also result in leaching heavy metal ions, which turn pose threat potential pollution groundwater.In response resolving above-mentioned problem, this paper simulated concentration distribution migration principle Cu 2+ various soils by applying COMSOL Multiphysics software, results show that diffusion...
In this study, vinyltriethoxysilane (TEVS) was introduced onto the surface of carbon fiber using liquid-phase oxidation and impregnation methods to incorporate vinyl groups fiber, thereby enhancing chemical bonding between norbornene-polyimide (PI-NA). Through a systematic study hydrolysis conditions concentration TEVS solution, optimal modification were determined. These used graft oxidized prepare carbon-fiber-reinforced PI-NA composites (CF/PI-NA). The results show that when treated with...
