Polymer brush-modified graphene oxide membrane with excellent structural stability for effective fractionation of textile wastewater

Conventional graphene oxide (GO) desalination membranes generally experience severe structural deterioration due to physical swelling. The strong surface negativity of the membrane also synchronously influences the diffusion/transport behaviors of all the solutes, leading to a low solute-solute selectivity. To address these issues, a novel poly (styrenesulfonic acid-co-4-vinylpyridine) brush-modified GO nanosheet (PB-GO) is designed and synthesized via atom transfer radical polymerization (ATRP) and is then employed to fabricate the GO membranes by a vacuum filtration approach, followed by chemical crosslinking with glutaraldehyde (GA). The sulfonate groups of the polymer enable excellent water dispersibility, while the pyridine groups are locally protonated under appropriate conditions, leading to the neutralization of the surface charge of the PB-GO nanosheets. The best performing membrane had a PB-GO mass loading of 0.3 g m(-2) (PB-GO-0.3). In addition to a high water permeability of 30.3 +/- 4.2 L m(-2) h(-1) bar(-1), this membrane also exhibits ultralow rejection of Na2SO4 (<6.9%) over a wide concentration range (1.0-20.0 g L-1) in a cross-flow operation mode, due to the suppressed charge repulsion effect. However, the typical dye molecules, e.g. Congo red, direct red 23, and direct red 80, could be effectively rejected (>98.3%) based on the size exclusion effect. As a result, the PB-GO-0.3 membrane provides a high solute-solute selectivity of 58.18, which far exceeds that of commercial and other reported nanofiltration membranes. Overall, we provide a facile strategy for designing a polymer brush-functionalized GO membrane for effective dye/salt fractionation to treat textile wastewater.

Post-synthetic modification of porous [Cu-3(BTC)(2)] (BTC = benzene-1,3,5-tricarboxylate) metal organic framework with molybdenum and vanadium complexes for the epoxidation of olefins and allyl alcohols

Two metal-organic frameworks (MOFs) were prepared based on post-synthetic modification (PSM) method. To design advanced functional material with enhanced catalytic activity, Cu-3(BTC)(2) (H3BTC = benzene-1,3,5-tricarboxylate) was synthesized and functionalized with 4-aminopyridine and 2-pyridine carboxaldehyde to achieve a supported bidentate Schiff base. Then, molybdenyl acetylacetonate MoO2(acac)(2) and vanadyl acetylacetonate VO(acac)(2) were immobilized on Schiff base functionalized Cu-3(BTC)(2). These newly prepared catalysts were studied by powder X-ray diffraction, Fourier transform infrared spectroscopy (FT-IR), atomic absorption spectroscopy (AAS), field emission scanning electron microscopy (FE-SEM), and also N-2 adsorption-desorption (BET method) analyses. After characterization, different parameters influencing the reaction were optimized. A comparative study of the catalytic activity was carried out in the epoxidation of various olefins and allylic alcohols over tert-butyl hydroperoxide (TBHP). The maximum conversion was achieved in the case of Mo-catalyst as an effective and selective catalyst in the epoxidation of allylic alcohols.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 24484-93-3. Quality Control of Methyl 4-chloropicolinate.

Tripodal tris(diamide) receptor having H-bond donors and acceptors on trindane platform for H2PO4- recognition

A new C-3v-symmetric tris(diamide) receptor 2 possessing both H-bond donor and acceptor sites was synthesized and characterized by various spectral data. The anion recognition ability of receptor 2 was investigated by H-1 NMR in DMSO-d(6). Among the tested anions (F-, Cl-, Br-, I-, NO3-, HSO4- and H2PO4-), the receptor 2 shows high selectivity towards H2PO4- anion. The amide-NH protons peaks of receptor 2 at delta 10.42 and delta 8.23 ppm were broadened and shifted to downfield region in the presence of H2PO4-. The appended arms with tris(diamide) H-bond donors and pyridine H-bond acceptors of receptor 2 provide a preorganized cavity to encapsulate the H2PO4- through multiple hydrogen bonds. The H-1 NMR titration measures the binding constant (K-a) of 293 M-1 for the host-guest complex formed between receptor 2 and H2PO4-. Further, the possible 3D structure of receptor 2 and its complex with H2PO4- anion was proposed through density functional theory method.

Ginsenoside Rb1 Protects Human Umbilical Vein Endothelial Cells against High Glucose-Induced Mitochondria-Related Apoptosis through Activating SIRT3 Signalling Pathway

Objective To investigate whether ginsenoside Rb1 (Rb1) can protect human umbilical vein endothelial cells (HUVECs) against high glucose-induced apoptosis and examine the underlying mechanism. Methods HUVECs were divided into 5 groups: control group (5.5 mmol/L glucose), high glucose (HG, 40 mmol/L) treatment group, Rb1 (50 mu mol/L) treatment group, Rb1 plus HG treatment group, and Rb1 and 3-(H-1-1,2,3-triazol-4-yl) pyridine (3-TYP, 16 mu mol/L) plus HG treatment group. Cell viability was evaluated by cell counting kit-8 assay. Mitochondrial and intracellular reactive oxygen species were detected by MitoSox Red mitochondrial superoxide indicator and dichloro-dihydro-fluorescein diacetate assay, respectively. Annexin V/propidium iodide staining and fluorescent dye staining were used to measure the apoptosis and the mitochondrial membrane potential of HUVECs, respectively. The protein expressions of apoptosis-related proteins [Bcl-2, Bax, cleaved caspase-3 and cytochrome c (Cyt-c)], mitochondrial biogenesis-related proteins [proliferator-activated receptor gamma coactivator 1-alpha, nuclear respiratory factor-1 and mitochondrial transcription factor A)], acetylation levels of forkhead box O3a and SOD2, and sirtuin-3 (SIRT3) signalling pathway were measured by immunoblotting and immunoprecipitation. Results Rb1 ameliorated survival in cells in which apoptosis was induced by high glucose (PP<0.01). Upon the addition of Rb1, mitochondrial and intracellular reactive oxygen species generation and malondialdehyde levels were decreased (P<0.01), while the activities of antioxidant enzymes were increased (PP<0.01). Rb1 preserved the mitochondrial membrane potential and reduced the release of Cyt-c from the mitochondria into the cytosol (P<0.01). In addition, Rb1 upregulated mitochondrial biogenesis-associated proteins (P<0.01). Notably, the cytoprotective effects of Rb1 were correlated with SIRT3 signalling pathway activation (P<0.01). The effect of Rb1 against high glucose-induced mitochondria-related apoptosis was restrained by 3-TYP (PP<0.01). Conclusion Rb1 could protect HUVECs from high glucose-induced apoptosis by promoting mitochondrial function and suppressing oxidative stress through the SIRT3 signalling pathway. Interested yet?

Synthesis of Succinylated Starches and Their Application as Adsorbents for the Removal of Phenol

Succinylated starches (SS) were prepared by the reaction of normal starch (NS) and porous starch (PS) with succinic anhydride (SA) in the presence of DMF solvent and base pyridine, respectively. The proton nuclear magnetic resonance and Fourier transform infrared were used to confirm the successful synthesis of the SS (SS1, SS2, SS3 and SS4, respectively). The X-ray diffractometer XPert PRO (Cu K alpha, lambda = 1.54 angstrom) was used to study the crystallinity of NS, PS and SS. The XRD analysis showed that the SS exhibited amorphous nature after succinylation. Thermogravimetric analysis and differential thermal analysis of NS, PS and SS showed that succinylation decreased the thermal stability. The morphology of the NS, PS and SS was studied by SEM. These SS were used as adsorbents for phenol removal. The adsorption efficiencies for phenol by NS, SS1, SS2, SS3 and SS4 were found to be 0.084 g/g, 0.165 g/g, 0.173 g/g, 0.183 g/g and 0.189 g/g, respectively.

Selective cyclization of S-substituted pyrimidinethione: Synthesis and antimicrobial evaluation of novel polysubstituted thiazolopyrimidine and thiazolodipyrimidine derivatives

The synthetic strategy is based on alkylation of 4-aryl-N-(4-chlorophenyl)-6-methyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxamide derivatives IV a-g, with some alkyl halides and alpha-haloketones, namely, methyl iodide, chloroacetonitrile, and phenacyl bromide to give the corresponding S-substituted derivatives Va-c. Treatment of IVa-c with ethyl bromoacetate in ethanol under reflux in the presence of potassium hydroxide solution led to the formation of N-(4-chlorophenyl)-7-methyl-3-oxo-5-(aryl)-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidine-6-carboxamide derivative VIII a-c in a single-step synthesis. On the other hand, compound IVa reacted with alpha-halo carbonitriles, namely, chloro acetonitrile, and monobromo malononitrile, to produce directly thiazolo[3,2-a]pyrimidine derivatives Xa and Xb, respectively, Compound Xb also reacted with each of formic acid, formamide, and ammonium thiocyanate to form thiazolodipyrimidine derivatives XI-XIII, respectively. Compound VIIIa-c coupled with arenediazonium salts in pyridine to give the corresponding 2-arylhydrazo derivatives XVIa-e. Compounds IV a-g and VIIIa-c were resynthesized under microwave irradiation. Some of the newly synthesized compounds were tested for their antimicrobial activities.

Design and photophysical studies of iridium(iii)-cobalt(iii) dyads and their application for dihydrogen photo-evolution

We report several new dyads constituted of cationic iridium(iii) photosensitizers and cobalt(iii) catalyst connected via free pendant pyridine on the photosensitizers. These dyads were studied by X-ray crystallography, electrochemistry, absorption and emission spectroscopy as well as theoretical calculations and were shown to efficiently produce H-2 under visible light irradiation. In every case, the dyad outperformed the equivalent system without a pendant pyridine. The dependence between irradiation wavelength and photocatalytic performances was also studied, with H-2 being evolved with turn-over numbers up to 295, 251, 188 and 78 mol(H2) mol(PS)(-1) under blue, green, yellow and red light, respectively.

Regioselective Synthesis of Novel [1,2,4]Triazolo[1,5-a]pyridine Derivatives

Herein we report the reaction of 2-(5-aryl-4H-1,2,4-triazol-3-yl)acetonitriles 1 a,b with appropriate Michael acceptors 2-4 to give novel [1,2,4]triazolo[1,5-a]pyridines 5-8, whose antioxidant properties have been investigated. A plausible reaction mechanism, supported by DFT calculations, has been proposed to explain the total observed regioselective formation of [1,2,4]triazolo[1,5-a]pyridine derivatives depending on the type of substituents on the Michael acceptor. Triazoles are well-known agents exhibiting antimicrobial,([1]) antitumor,([2]) anti-inflammatory,([3]) antihypertensive,([4]) anticonvulsant,([5]) antiviral([6]) and analgesic([7]) biological activities. On the other hand, pyridine is the key core of heterocyclic derivatives showing a variety of pharmacological properties.([8-12]) Several studies have revealed that a combination of different bioactive molecules, having different mechanisms of action, is a current strategy affording useful therapeutic agents.([13]) This is the case of the [1,2,4]triazolo[1,5-a] pyridine heterocyclic motif,([14]) present in a number of bioactive compounds,([15]) and largely used in materials chemistry.([16]) Accordingly, diverse synthetic methods have been described for the synthesis of differently substituted [1,2,4]triazolo[1,5-a]pyridines.([17-24]) Our group has recently reported the ultrasound-promoted facile and convenient one-pot procedure for the synthesis of novel [1,2,4]triazolo[1,5-a]pyridines in short reaction times and high yields, based on the reaction of 2-(5-aryl-4H-1,2,4-triazol-3-yl)acetonitriles, malononitrile (or ethyl cyanoacetate) and aromatic aldehydes, in absolute ethanol, in the presence of IRA-400.([25])
