Light metal borohydrides/amides combined hydrogen storage systems: composition, structure and properties

The implementation of a future economy based on hydrogen-related energy needs an urgent development of efficient, safe, and economic solid-state hydrogen-storage materials. During the search process for novel materials for storing hydrogen, research interests in the past few decades have been intensively focused on light metal borohydrides and amides as two representative chemical complex hydrides with high hydrogen capacities. Recently, a large number of studies have reported new borohydride/amide combined systems that expand the scope of hydrogen-storage materials. Here, we review the interaction between light metal borohydrides and amides for storing hydrogen, with a special emphasis on the synthetic strategies and structural, physical, and chemical properties, which reveal a correlation between the composition, structure, and dehydrogenation properties and also provide general principles to the design of new combined systems with tailored functionality. This review also demonstrates the current progress on the dehydrogenation kinetic improvement of borohydride/amide combined systems.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 212322-56-0, you can contact me at any time and look forward to more communication. HPLC of Formula: C18H22N4O3.

Beneficial actions of the [A14K] analog of the frog skin peptide PGLa-AM1 in mice with obesity and degenerative diabetes: A mechanistic study

The antidiabetic actions of [A14K]PGLa-AM1, an analog of peptide glycine-leucine-amide-AM1 isolated from skin secretions of the octoploid frog Xenopus amieti, were investigated in genetically diabetic-obese db/db mice. Twice daily administration of [A14K]PGLa-AM1 (75 nmol/kg body weight) for 28 days significantly (P < 0.05) decreased circulating blood glucose and HbA1c and increased plasma insulin concentrations leading to improvements in glucose tolerance. The elevated levels of triglycerides, LDL and cholesterol associated with the db/db phenotype were significantly reduced by peptide administration. Elevated plasma alanine transaminase, aspartic acid transaminase, and alkaline phosphatase activities and creatinine concentrations were also significantly decreased. Peptide treatment increased pancreatic insulin content and improved the responses of isolated islets to established insulin secretagogues. No significant changes in islet beta-cell and alpha-cell areas were observed in [A14K]PGLa-AM1 treated mice but the loss of large and medium-size islets was prevented. Peptide administration resulted in a significant (P < 0.01) increase in islet expression of the gene encoding Pdx-1, a major transcription factor in islet cells determining beta-cell survival and function, resulting in increased expression of genes involved with insulin secretion (Abcc8, Kcnj11, Slc2a2, Cacn1c) together with the genes encoding the incretin receptors Glp1r and Gipr. In addition, the elevated expression of insulin signalling genes (Slc2a4, Insr, Irs1, Akt1, Pik3ca, Ppm1b) in skeletal muscle associated with the db/db phenotype was downregulated by peptide treatment These data suggest that the anti-diabetic properties of [A14K]PGLa-AM1 are mediated by molecular changes that enhance both the secretion and action of insulin.

Base-Mediated 1,6-Aza-Michael Addition of Heterocyclic Amines and Amides to para -Quinone Methides Leading to Meclizine-, Hydroxyzine- and Cetirizine-like Architectures

An expeditious, cost-effective synthetic methodology for a wide range of nitrogen-containing unsymmetrical trisubstituted methanes (TRSMs) is reported. The synthesis involves base-mediated 1,6-conjugate addition of heterocyclic amines and amides to substituted para -quinone methides, giving the unsymmetrical TRSMs in moderate to very good yields (up to 83%) in one pot. The low cost, mild temperature, high atom economy and yields, easy scale-up and broad substrate scope are some of the salient features of this protocol. Further, the methodology could be extended for the synthesis of meclizine-, -hydroxyzine- and cetirizine-like molecules. The structure of one such compound, 2,6-di- tert -butyl-4-((4-chlorophenyl)(4-methylpiperazin-1-yl)methyl)phenol, was determined by single crystal X-ray analysis.

Preparation and Properties of a Novel Semi-IPN Slow-Release Fertilizer with the Function of Water Retention

A new semi-interpenetrating polymer network (semi-IPN) slow-release fertilizer (SISRF) with water absorbency, based on the kaolin-g-poly(acrylic acid-co-acrylic amide) (kaolin-g-P(AA-co-AM)) network and linear urea-formaldehyde oligomers (UF), was prepared by solution polymerization. Nutrients phosphorus and potassium were supplied by adding dipotassium hydrogen phosphate during the preparation process. The structure and properties of SISRF were characterized by various characterization methods. SISRF showed excellent water absorbency of 68 g g(-1) in tap water. The slow-release behavior of nutrients and- water-retention capacity of SISRF were also measured. Meanwhile, the swelling kinetics was well described by a pseudo-second-order kinetics model. Results suggested the formation of SISRF with simultaneously good slow-release and retention capacity, which was expected to apply in modern agriculture and horticulture.

Block copolymer membranes with catecholic bolaamphiphile assemblies

We report the first use of the assemblies of catecholic bolaamphiphilic compound, i.e., bis-(N-alpha-amido-3,4-di-hydroxyphenylalanine) – 1,7-heptane dicarboxylate (DOPA-C7), as an organic filler for gas separation membranes. Specifically, the membranes were prepared by adding the assembly fillers to a block copolymer matrix, i.e., nonpolar polystyrene-b-polybutadiene-b-polystyrene (SBS) or polar poly (ether-b-amide) (PEBAX). The interaction between the filler and matrix was investigated regarding the structure, morphology, and CO2/N-2 separation performance. The strongly interacting PEBAX/DOPA-C7 membranes showed a typical trade-off behavior, i.e., a decrease in CO2 permeability and increase in CO2/N-2 selectivity with the filler contents. In contrast, the weakly interacting SBS/DOPA-C7 interestingly showed an improved CO2/N-2 selectivity, from 14.1 to 21.1, with a slight increase in CO2 permeability (from 347.5 to 349.7 Barrer) owing to the catechol group of DOPA-C7 that can function as a Lewis base. This indicates that very strong interactions between the polymeric matrix and filler could have a negative impact on the gas separation performance. This work not only explores the importance of a polymer matrix, but also opens up the feasibility of using a catecholic compound in gas separation membranes.

Conversion of an amide to a high-energy thioester by Staphylococcus aureus sortase A is powered by variable binding affinity for calcium

Thioesters are key intermediates in biology, which often are generated from less energy-rich amide precursors. Staphylococcus aureus sortase A (SrtA) is an enzyme widely used in biotechnology for peptide ligation. The reaction proceeds in two steps, where the first step involves the conversion of an amide bond of substrate peptide into a thioester intermediate with the enzyme. Here we show that the free energy required for this step is matched by an about 30-fold increase in binding affinity of a calcium ion at the calcium binding site of SrtA, which is remote from the thioester bond. The magnitude of this allosteric effect highlights the importance of calcium for the activity of SrtA. The increase in calcium binding affinity upon binding of substrate not only achieves catalytic formation of an energy-rich intermediate in the absence of nucleotide triphosphates or any tight non-covalent enzyme-substrate interactions, but is also accompanied by accumulation of the labile thioester intermediate, which makes it directly observable in nuclear magnetic resonance (NMR) spectra.

Nitric Oxide (NO) separation from flue gas by chemical modified mesoporous silica

Three kinds of chemically modified silica were prepared to adsorb NO by surface modifying with vinyltriethoxysilane, acrylic acid and acryl amide respectively, and characterized by N-2 adsorption experiments, Fourier transform infrared spectroscopy, scanning electron microscopy and thermo-gravity analysis. The results showed that -COOH and -CONH2 in the monomers had been grafted on the silica surface, and the pore volumes of S-1, S-2 and S-3 decreased and exhibited the mesoporous structure; all the modified adsorbents could maintain steady under 300 degrees C. NO adsorption experiments were also carried out and the results suggested that the silica modified with acryl amide had the best NO adsorption capacity due to the relative large surface area and the stronger hydrogen bonds between NO molecules and the functional groups. The adsorbed NO molecules could be well desorbed by purging with N-2 so that the adsorbents could be recycled and NO resource also had the chance to be reused.

Some Hydrated Molecular Complexes of 4-Cyanophenylboronic Acid: Significance of Water in the Structure Stabilization by Theoretical Investigation

Molecular complexes 1a-1c of 4-cyanophenyl-boronic acid, 1, with N-donor compounds, 4,4′-bipyridine (a), 1,2-bis(4-pyridyl)ethene (b), and melamine (c), respectively, have been prepared, in the form of single crystals, by slow solvent evaporation method. Crystal structures of all the complexes have been determined by the X-ray diffraction technique. All the complexes 1a-1c were noted to be crystallized as hydrates. Variations in the patterns of intermolecular interactions among the complexes and the geometrical features of 1 have been analyzed comparing with the features found in the native structure of 1 by determining its crystal structure also. The -B(OH)(2) moiety in the native form of 1 and also in the molecular complexes 1a-1c adopts syn-anti conformation. Further, calculations were performed, using the DFT-D3 method, to rationalize the propensity of formation of hydrate structures and to deliberate the observed structural features with respect to the strength of the intermolecular interactions, for instance, hydrogen bonds.
