The effect of carbon nanotube (CNT) functionalization in altering the properties of epoxy-CNT composites is presented. The presence of functional groups effectively influenced the colloidal behavior of CNTs in the precursor epoxy resin and the hardener triethylenetetramine (TETA), which affected the synthesis process and eventually the interfacial interactions between the polymer matrix and the CNTs. The physical, thermal, and electrical properties of the composites exhibited strong dependence on the nature of functionalization. At a 0.5-wt% CNT loading, the enhancement in tensile strength was found to be 7.2%, 11.2%, 11.4%, and 14.2% for raw CNTs, carboxylated CNTs, octadecyl amide-functionalized CNTs, and hydroxylated CNTs, respectively. Glass transition temperatures (T-g) also varied with the functionalization, and composites prepared using hydroxylated CNTs showed the maximum enhancement of 34%.

BACKGROUND: The glycoproteinoses are a subgroup of lysosomal storage diseases (LSDs) resulting from impaired degradation of N-linked oligosaccharide side chains of glycoproteins, which are commonly screened by detecting the accumulated free oligosaccharides (FOSs) in urine via thin layer chromatography (TLC). The traditional TLC method suffers from limited analytical sensitivity and specificity and lacks quantification capability. Therefore, we developed an analytically sensitive and relatively specific assay using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) for urinary FOS analysis and validated its use for urine screening of glycoproteinoses and other LSDs. METHODS: Urine volumes equivalent to 30 mu g of creatinine were derivatized with butyl-4-aminobenzoate and then purified through a solid-phase extraction cartridge. A 7-min UPLC-MS/MS analysis was performed on a triple quadrupole mass spectrometer using an amide column for separation of derivatized FOS. Urine samples from >100 unaffected controls and 37 patients with various LSDs were studied. RESULTS: Relative quantification was conducted on 7 selected FOSs using a single internal standard, which allowed the identification of patients with 1 of 8 different LSDs: aspartylglucosaminuria, alpha-fucosidosis, alpha-mannosidosis, beta-mannosidosis, beta-galactosidase deficiency, Sandhoff disease, sialidosis, and galactosialidosis. Patients treated with hematopoietic stem cell transplant show decreased FOS responses compared with untreated patients. CONCLUSIONS: This UPLC-MS/MS assay offers a valuable tool for screening of glycoproteinoses and other LSDs, with potential use for future treatment monitoring.

The fluorinated Nafion is replaceable by the non-fluorinated clean sulfonated poly (ether ether ketone) for hydrogen-based fuel cell. The acid-base blending of PAI to clean sulfonated poly ether ether ketone (SPEEK) increased the thermal, mechanical, and oxidative properties and decreased the conductivity. It interpreted that higher stability properties appeared on the blended membrane. The loading of BaCeO3 nanoparticles in the SPEEK/poly (amide-imide) (PAI) matrices was done via solution casting process. This outcome provides improved conductivity, ion-exchange property, water uptake (WU) with controlled stability due to the good interfacial interplay among nanoparticles and polymer. The high conductivity (14.98 x 10(-3) S cm(-1) at 80 degrees C) was reached by SPEEK/PAI /BaCeO3 (90/10/06 wt%) membrane (B3) measured in the electrochemical four-probe impedance spectroscopy. Its current density and power density values are 269 mA cm(-2) and 66 mW cm(-2), respectively. The voltage retention of the B3 membrane was maintained almost at 0.92 V and degradation of voltage after 20 hours in the durability study was about 0.01 V.

The enantioselective functionalization of nonactivated enantiotopic secondary C-H bonds is one of the greatest challenges in transition-metal-catalyzed C-H activation proceeding by an inner-sphere mechanism. Such reactions have remained elusive within the realm of Pd-0 catalysis. Reported here is the unique reactivity profile of the IBiox ligand family in the Pd-0-catalyzed intramolecular arylation of such nonactivated secondary C-H bonds. Chiral C-2-symmetric IBiox ligands led to high enantioselectivities for a broad range of valuable indane products containing a tertiary stereocenter, as well as the arylation of secondary C-H bonds adjacent to amides. Depending on the amide substituents and upon control of reaction time, indanes containing labile tertiary stereocenters were also obtained with high enantioselectivities. Analysis of the steric maps of the IBiox ligands indicated that the level of enantioselectivity correlates with the difference between the two most occupied and the two less occupied space quadrants, and provided a blueprint for the design of even more efficient ligands.

Soluble epoxide hydrolase (sEH) is an alpha/beta hydrolase fold protein and widely distributed in numerous organs including the liver, kidney, and brain. The inhibition of sEH can effectively maintain endogenous epoxyeicosatrienoic acids (EETs) levels and reduce dihydroxyeicosatrienoic acids (DHETs) levels, resulting in therapeutic potentials for cardiovascular, central nervous system, and metabolic diseases. Therefore, since the beginning of this century, the development of sEH inhibitors is a hot research topic. A variety of potent sEH inhibitors have been developed by chemical synthesis or isolated from natural sources. In this review, we mainly summarized the interconnected aspects of sEH with cardiovascular, central nervous system, and metabolic diseases and then focus on representative inhibitors, which would provide some useful guidance for the future development of potential sEH inhibitors.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 2432-99-7, you can contact me at any time and look forward to more communication. Recommanded Product: 2432-99-7.

Rigid ladder polymers represent a unique polymer architecture but have limited synthetic accessibility and structural diversity. Using catalytic arene-norbornene annulation (CANAL) polymerization, we synthesized ladder polymers consisting of rigid and kinked norbornyl benzocyclobutene backbones and bearing various functional groups, such as alcohol, amine, ester, carbamate, amide, benzyl bromide, azide, and heterocycles. The incorporation of functional groups was achieved by either copolymerization of functionalized ladder-type dinorbornenes or postpolymerization functionalization. Functionalization of ladder polymers allows modification of their solubility, compatibility, and other properties, expanding their utilities. These ladder polymers remain microporous and highly glassy, which are desirable for separation and high-temperature applications.

The present study reports one of the first attempts on the design and development of an enzymaticbiodegradable theranostic fluorescence resonance energy transfer (FRET) probe constructed on L-amino acid polymer nanoassemblies and demonstrates the proof-of-concept in live cell bioimaging. L-Aspartic acid was converted into amide or carbamate pendants containing bis-carboxylic acid ester monomers, and they were subjected to melt polymerization along with commercial diols to produce amphiphilic aliphatic polyesters. Nanoparticles of size <200 nm were obtained because of selfassembly of these amphiphilic polyesters in an aqueous medium. These nanoparticles exhibited excellent encapsulation capability for green-fluorescent anti-inflammatory drug curcumin (CUR) and highly luminescent red-fluorophore Nile red (NR) to yield a CUR-NR theranostic FRET probe. Detailed photophysical studies were carried out to demonstrate photoexcitation energy transfer from CUR to NR for the occurrence of the FRET phenomena. The theranostic FRET probe was found to be very stable at extracellular environment and underwent biodegradation at the intracellular regions for delivery of the loaded cargoes. As a result, the theranostic FRET probe functioned as turn-on at the extracellular level and became turnoff at the intracellular level under lysosomal enzyme-responsiveness. The polymer nanoparticle was nontoxic to cells, whereas its CUR encapsulated nanoparticle showed relatively good cytotoxicity in breast cancer cell lines. Live cell confocal microscopy studies using lysotracker staining confirmed the colocalization of CUR as well as NR within the polymer nanoparticles in the lysosomes for enzymatic-biodegradation. Selective photoexcitation experiments in the confocal microscope were carried out to study the FRET probe action in cancer cells. Time-dependent FRET imaging directly supported the occurrence of FRET at the intracellular level and enabled the real-time drug release studies. The present approach opens natural resource-based biodegradable theranostic FRET probes for bioimaging application.

Asymmetric 1,4-addition reactions with nitroalkenes are valuable because the resulting chiral nitro compounds can be converted into various useful species often used as chiral building blocks in drug and natural product synthesis. In the present work, asymmetric 1,4-addition reactions of arylboronic acids with nitroalkenes catalyzed by a rhodium complex with a chiral diene bearing a tertiary butyl amide moiety were developed. Just 0.1 mol% of the chiral rhodium complex could catalyze the reactions and give the desired products in high yields with excellent enantioselectivities. The homogeneous catalyst thus developed could be converted to a reusable heterogeneous metal nanoparticle system using the same chiral ligand as a modifier, which was immobilized using a polystyrene-derived polymer with cross-linking moieties, maintaining the same level of enantioselectivity. To our knowledge, this is the first example of asymmetric 1,4-addition reactions of arylboronic acids with nitroalkenes in a heterogeneous system. Wide substrate generality and high catalytic turnover were achieved in the presence of sufficient water without any additives such as KOH or KHF2 in both homogeneous and heterogeneous systems. Various insights relating to a rate-limiting step in the catalytic cycle, the importance of water, role of the secondary amide moiety in the ligand, and active species in the heterogeneous system were obtained through mechanistic studies.
