Owing to the specific porous structure which could provide additional passage channel for some molecules, metal organic frameworks are attractive candidates enhancing permeability and selectivity of membranes in pervaporation, reverse osmosis, gas separation. In this experiment, Ag@UiO-66-NH2 was introduced into polyamide separation layer by interfacial polymerization triethylenetetramine 1,3,5-benzenetricarboxylic acid chloride nanofiltration. The results indicated that nanoparticles did...
The thermally induced phase separation (TIPS) process was employed to prepare poly (vinylidene fluoride-co-hexafluoropropylene; PVDF-HFP) microporous membranes using sulfolane as the diluent. diagram of PVDF-HFP/sulfolane system drawn and analyzed. effects polymer content in casting solution cooling rate on cross-sectional morphology, crystallinity, crystal structure, porous structure resulting were investigated scanning electron microscopy (SEM), differential calorimetry (DSC), X-ray...
The mesophase in the as‐stretched poly( L ‐lactide) (PLLA) exhibits low thermal stability and undergoes melting around T g . As a consequence, without constraints PLLA can recover to its original (unstretched) length while being held above Upon constrained annealing at 70°C is transformed into highly oriented crystals, responsible for little free shrinkage superior dimensional stability. At same time, molecular orientation amorphous phase first decreases significantly due thermodynamic...
Abstract The effect of amorphous poly( D , L ‐lactide) (PDLLA) on the molecular orientation and crystallization crystalline (PLLA) stretching is reported in this study. It indicated that presence PDLLA its miscible blends with PLLA not favorable for either cohesive mesophase formation below T g or strain‐induced above at strains beyond segmental extensibility limit. Because lack constraints imposed by crystals, oriented segments are liable to slide each other recoil, responsible...
We conducted a nitrogen (N) and phosphorus (P) addition experiment in Qianjiangyuan National Park 2015, to investigate the response of ammonia-oxidizing microorganisms denitrifying microorganisms. There were four treatments, including N (N), P (P), NP, control (CK). Soil samples collected April (wet season) November (dry 2021. The abundance amoA gene (i.e., archaea, AOA; bacteria, AOB; comammox) microbial genes nirS, nirK, nosZ) determined using quantitative PCR approach. results showed that...
Microorganisms produce extracellular enzymes to meet elemental requirements and cope with stoichiometric imbalances of resources. To gain insights into the cycling C, N, P, activities C∶N∶P acquisition have been extensively investigated. detect effects long-term fertilization practices on soil nutrient balance characteristics enzymatic stoichiometry in black soil, four different treatments were selected： no （CK）, nitrogen fertilizer （N）, phosphorus （P）, combination fertilizers （NP）. Soil...
Incorporation of an ionic liquid, nonvolatile and thermally stable, promoted formation ring-banded spherulites in poly (l-lactide) (PLLA) during its sol–gel transition. Their is correlated with low viscosity insignificant chain entanglements the mixtures induced by liquid. In addition to a driving force for lamellar twisting that depended on crystallization temperatures, it believed reduced resistance caused liquid plays vital role PLLA from mixtures. This study gives further insights into...
