In this study, silver nanoparticles (AgNPs) were immobilized on the surface of polyethylene terephthalate (PET) membrane using diethylenetriamine (DETA) as a chemical linker. The molecule DETA was attached to PET via an amide bond following scission polyester ester surface. AgNPs diethylenetriamine-modified silver-nitrogen covalent bond. silver-coated, DETA-modified and unmodified membranes cha...

In this work, the critical diameter for detonation was measured for Nitromethane (NM) sensitized with two different amines: Diethylenetriamine (DETA) and Triethylamine (TEA). The critical diameter in glass and polyvinylchloride tubes is found to decrease rapidly as the amount of sensitizer is increased, then increase past a critical amount of sensitizer. Thus the critical diameter reaches a min...

Polyols are groups of organic compounds which contain carbon and randomly linked to other atoms, especially carbon-carbon carbon-hydrogen. These mainly used as reactants make polymers. Among biopolymers, lignin is regarded the base a new polymer in polyol construction. The present study aimed investigate effects amine type (diethylenetriamine ethylenediamine) on modification lignin-based polyol...

porous hollow glass microspheres have many uses, including encapsulation of active materials. in this paper a fast and facile method for fabricating porous hollow glass-microspheres was demonstrated by etching them using dilute hydrofluoric acid. then, a highly reactive amine was infiltrated into the etched glass microspheres. scanning electron microscopy was conducted for the hollow glass micr...

The objectives of this study were to evaluate the effects of a nitric oxide (NO) donor on embryo development in vitro and on implantation of embryos in vivo in mice. Mouse embryos (2-cell) were incubated in media containing different concentrations of diethylenetriamine/NO (DETA/NO), a nitric oxide donor, and development was monitored daily for 4 days. Specificity of NO effects was assessed by ...

Abstract Tetranuclear hydroxo complexes [La 4 (Deta) (OH) (Tfa) 3 (DetadcH) 2 ](HTfa)(H O) 7 ( I ) and [Nd ](H n II with diethylene- N , ′-dicarbamate anions (DetadcH – are synthesized for the first time by reactions of lanthanum trifluoroacetate neodymium a solution diethylenetriamine in air under self-controlled hydrolysis conditions characterized X-ray diffraction, powder IR spectroscopy, el...

Two polymers were prepared from diglycidyl ether of bisphenol A (DGEBA) and triglycidyl p-aminophenol (TGAP) epoxy resins, using the same hardener diethylenetriamine (DETA). The obtained compared in terms structural, optical, mechanical, thermal dielectric properties. Dielectric spectroscopy dynamic mechanical analysis indicated presence dipolar relaxations both polymers, interfacial one only f...

Abstract In this work, characterization and kinetics of CO2 absorption in potassium carbonate (K2CO3) solution promoted by diethylenetriamine (DETA) were investigated. Kinetics measurements performed using a stirred cell reactor the temperature range 303.15–323.15 K total concentration up to 2.5 kmol m?3. The density, viscosity, physical solubility, diffusivity rate determined. reaction between...

Composite photocatalysts are crucial for photocatalytic hydrogen evolution. In this work, ZrO2/CdSe-diethylenetriamine (ZrO2/CdSe-DETA) heterojunction nanocomposites synthesized, and efficiently stably catalyzed evolution under visible light. X-ray photoelectron spectroscopy (XPS) high resolution transmission electron microscope (HRTEM) confirm the formation of heterojunctions between ZrO2 (ZO)...

In an attempt to integrate biological components with silicon-based devices and systems, artificial silane surfaces have been successfully used to grow motoneurons in a defined environment. In this study we characterized the morphology and electrophysiology of purified rat embryonic (E14) motoneurons grown on a self-assembled monolayer (SAM) of N-1[3-(trimethoxysilyl)propyl]diethylenetriamine (...
