Inkjet printing of particle-free silver conductive ink with low sintering temperature on flexible substrates

A facile synthesis method was developed to prepare the particle-free silver organic conducive ink, which contains silver-amide complex dispersed in glycol. Electrical and morphological characterizations were carried out to assess the performance of the ink. The patterns printed by a commercial inkjet printer (Epson R230) were treated at different temperatures and time to optimize the electrical and adhesion properties. The film sintered at 140 degrees C for 40 min showed a low electrical resistivity (about 5 mu Omega.cm) owing to the transformation of point contact to surface contact. These good performances indicated a penitential application in flexible electronics.

Synthesis and Properties of Bio-Based Nonisocyanate Thermoplastic Polyoxamide-Ureas

A green route is presented to synthesize bio-based nonisocyanate thermoplastic polyoxamide-ureas (POXAUs) containing flexible poly(propylene oxide) segments. A hexanedioxamide-diester (HDODE) was synthesized from the reaction of 1,6-hexanediamine with excessive diethyl oxalate. Four H2N- terminated polyoxamide prepolymers (PrePOXAs) were synthesized through melt polycondensation of HDODE with O,O’-bis(2-aminopropyl) poly(propylene glycol). Chain extension of PrePOXAs was conducted with bis(hydroxyethyl) hexanediurethane as a chain extender, and four chain-extended POXAs or POXAUs were prepared. The POXAUs were characterized by size exclusion chromatography, Fourier transform infrared, H-1 NMR, wide-angle X-ray scattering, differential scanning calorimetry, thermogravimetric analysis, and tensile testing. POXAUs show M-n up to 29 900 g mol(-1), melting temperature from 148 to 156 degrees C, initial decomposition over 242 degrees C, tensile strength up to 60 MPa, and elongation at break from 8 to 16%. Crystallized bio-based thermoplastic poly(oxamide urea)s with excellent thermal and mechanical properties were successfully synthesized through a nonisocyanate route.

Synthesis of magnetic Fe3O4@SiO2@Cu-Ni-Fe-Cr LDH: an efficient and reusable mesoporous catalyst for reduction and one-pot reductive-acetylation of nitroarenes

Magnetically recoverable Fe3O4@SiO2@Cu-Ni-Fe-Cr LDH was prepared under co-precipitation conditions. Characterization of the mesoporous catalyst was confirmed using Fourier-transformed infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, vibration sample magnetometer, Brunauer-Emmett-Teller, thermogravimetric, differential thermogravimetric analyses and transmission electron microscopy. Reduction of nitroarenes to the corresponding arylamines and one-pot reductive-acetylation of nitroarenes to acetanilides were carried out successfully by nanoparticles of the immobilized Cu-Ni-Fe-Cr layered double hydroxide on silica-coated Fe3O4 in water as a green solvent. All reactions were carried out within 6-22min affording arylamines and N-arylacetamides in high-to-excellent yields. Reusability of the core-shell nanocatalyst was examined six times without significant loss of its catalytic activity. [GRAPHICS]

Caffeic Acid Alkyl Amide Derivatives Ameliorate Oxidative Stress and Modulate ERK1/2 and AKT Signaling Pathways in a Rat Model of Diabetic Retinopathy

The purpose of this study was to examine the neuroprotective effects of caffeic acid hexyl (CAF6) and dodecyl (CAF12) amide derivatives on the early stage of retinopathy in streptozotocin-induced diabetic rats. Animals were divided in five groups (n=8/group); one group consisted of non-diabetic rats as control, while the other four were diabetic animals either non-treated or treated with CAF6, CAF12 or resveratrol intravitreally for four weeks. Retinal superoxide dismutase (SOD) activity and 8-iso-prostaglandin F-2 alpha (iPF(2 alpha)) levels were evaluated by an ELISA assay. Phosphorylation of ERK1/2 and AKT was determined by immunoblotting in retinal homogenates. Retinal morphology was also examined using light microscopy. Treatment with CAF6 and CAF12 increased retinal SOD activity, while it decreased iPF(2 alpha) levels in diabetic rats. Phosphorylation of ERK1/2 was increased, while AKT phosphorylation was decreased in diabetic rats compared to normal control and these alterations were significantly reversed in diabetic rats treated with CAF6 and CAF12. Furthermore, thickness of the whole retinal layer, outer nuclear layer, and ganglion cell count were decreased in diabetic rats compared to control and CAF6 and CAF12 treatments prevented these changes. CAF6 and CAF12 seem to be effective agents for treatment of diabetic retinopathy via attenuation of retinal oxidative stress and improvement of neuronal survival signaling.

Mesoporous zirconia nanoparticles as drug delivery systems: Drug loading, stability and release

Drug delivery systems have been a milestone in medical research in the last twenty years, still representing a key aspect of innovation and evolution in pharmacokinetics and pharmacodynamics. Among several proposed solutions, inorganic mesoporous materials could be a promising vehicle. Their specific chemical-physical properties make them ideal candidates for the adsorption and loading of active pharmaceutical ingredients (API). Recently, mesoporous zirconia nanoparticles (MZNs) have been described as a novel drug delivery system due to their high surface area and biocompatibility. In this work, we investigated the loading and release efficiencies of a wide range of API on MZNs characterized by suitable pore volume and versatility, focusing on the integrity of the released drugs investigated through solution NMR and E SI-MS techniques. In order to explore the potentialities of MZNs for biomedical applications, we selected ibuprofen, N-acetyl-L-cysteine, vancomycin, gentamicin, nitrofurantoin, and indomethacin as benchmark API characterized by a wide range of polarity, molecular weight and presence of different functional groups. MZNs showed to efficiently load and release most of the API investigated. Long time loadings were also investigated observing that, after more than three months, no side reaction occurred on the released drugs except for intrinsically more labile API like NTF and NAC. MZNs ensured high inertness towards a wide range of functional groups such as aliphatic and aromatic amides, acetals of sugar residues as well as several chiral moieties bearing tertiary stereocenters.

Reactivity of phosphorus mononitride and interstellar formation of molecules containing phospazo linkage: A computational study on the reaction between HSi (X-2 Pi) and PN (X-1 Sigma(+))

Phosphorus mononitride (PN) shows some interesting chemistry due to its low dissociation energy (compared to N-2) and small dipole moment (zero dipole moment for N-2). In this work, a reaction between HSi (X-2 Pi) and PN (X-1 Sigma(+)) has been studied using various computational methods. Analysis of the doublet surface of the HSi thorn PN reaction indicates that the reaction is exothermic in nature leading to the formation of various products. In view of the barrierless association of the reactants and exothermic nature for the product formation, it is suggested that species like HPNSi, cyclic-SiN(H) P (these two most stable isomers have phosphazo linkage) and HSiNP (third most stable isomer has phosphdiazo linkage) can possibly be detected in the interstellar medium. In view of the potential applications of phosphazo compounds in amide synthesis and pervasive nature of amide linkages in the nature, possible interstellar prebiotic applications can be advocated for these compounds.

The structure and role of lactone intermediates in linkage-specific sialic acid derivatization reactions

Sialic acids occur ubiquitously throughout vertebrate glycomes and often endcap glycans in either alpha 2,3- or alpha 2,6-linkage with diverse biological roles. Linkage-specific sialic acid characterization is increasingly performed by mass spectrometry, aided by differential sialic acid derivatization to discriminate between linkage isomers. Typically, during the first step of such derivatization reactions, in the presence of a carboxyl group activator and a catalyst, alpha 2,3-linked sialic acids condense with the subterminal monosaccharides to form lactones, while alpha 2,6-linked sialic acids form amide or ester derivatives. In a second step, the lactones are converted into amide derivatives. Notably, the structure and role of the lactone intermediates in the reported reactions remained ambiguous, leaving it unclear to which extent the amidation of alpha 2,3-linked sialic acids depended on direct aminolysis of the lactone, rather than lactone hydrolysis and subsequent amidation. In this report, we used mass spectrometry to unravel the role of the lactone intermediate in the amidation of alpha 2,3-linked sialic acids by applying controlled reaction conditions on simple and complex glycan standards. The results unambiguously show that in common sialic acid derivatization protocols prior lactone formation is a prerequisite for the efficient, linkage-specific amidation of alpha 2,3-linked sialic acids, which proceeds predominantly via direct aminolysis. Furthermore, nuclear magnetic resonance spectroscopy confirmed that exclusively the C2 lactone intermediate is formed on a sialyllactose standard. These insights allow a more rationalized method development for linkage-specific sialic derivatization in the future.
