This paper studied the synthesis, characterization and use of the magnetic chitosan nanogel for carrying meleimidic compounds. The hydrogel polymer was prepared using O-carboxymethylchitosan, which was crosslinked with epichlorohydrin for subsequent incorporation of iron oxide magnetic nanoparticles. The characterizat…
Novel polyaniline (PANI)/cellulose filament fibers were spun from hydrophobic PANI and hydrophilic cellulose complex solution dissolved in aqueous solution containing 7 wt% NaOH/ 12 wt% urea as solvent by wet-spinning. At low PANI content, the composite fibers realized a transition from an insulator to semiconductor.
Yttria in Pt/TiO <sub>2</sub> catalyst improved the Pt dispersion and stabilized the structure, and hence enhanced the low-temperature activity and stability.
Hierarchical MnO <sub>2</sub> microspheres assembled by nano thin film are fabricated through an environmental route with subsequent drying under vacuum, and exhibit remarkable removal efficiency of heavy metal ions in water treatment.
Theoretical and experimental studies of the corrosion inhibition effect of nitrotetrazolium blue chloride on copper in 0.1 M H <sub>2</sub> SO <sub>4</sub> .
In this chapter, we will review the recent theoretical developments on the properties of low-dimensional Transition-Metal diChalcogenides (TMCs) for applications in nano- and opto-electronics. We will compare physical properties, such as electronic structure or lattice dynamics, and show that quantum confinement to lo…
A new high-level book for professionals from Atlantis Press providing an overview of nanotechnologies now and their applications in a broad variety of fields, including information and communication technologies, environmental sciences and engineering, societal life, and medicine, with provision of customized treatmen…
The history of solid solution strengthened high temperature titanium alloys was briefly reviewed and those alloys developed in the UK,USA and Russia were compared. Three kinds of alloys,Ti55,Ti60 and Ti65,covering the temperature range of 550- 650℃,and related welding technology were introduced. Suggestions for perfec…
We present a microfluidic patterning system for fabricating nanostructured Ag thin films via a polyol method. The fabricated Ag thin films can be used immediately in a real-time SERS sensing system. The Ag thin films are formed on the inner surfaces of a microfluidic channel so that a Ag-patterned Si wafer and a Ag-pa…
Here we report a perylene bisimide (PBI) based gelator molecule that contains neither a long alkyl chain nor any other solubilizing group which are considered to be essential moieties of organogelators. Instead, the solubility of the newly designed PBI gelator 4a is imparted by a contorted aromatic core. Its self-asse…
A single phase emission-tunable Sr <sub>7</sub> La <sub>3</sub> [(PO <sub>4</sub> ) <sub>2.5</sub> (SiO <sub>4</sub> ) <sub>3</sub> (BO <sub>4</sub> ) <sub>0.5</sub> ](BO <sub>2</sub> ):Ce <sup>3+</sup> ,Mn <sup>2+</sup> phosphor was synthesized and the photoluminescence, energy-transfer mechanism and thermal properti…
Single-crystals of vaterite, the least-stable anhydrous polymorph of CaCO3, are rare in biogenic and synthetic systems. We here describe the synthesis of high aspect ratio single crystal vaterite rods under additive-free conditions by precipitating CaCO3 within the cylindrical pores of track-etch membranes.
Highly soluble phenylethynyl-terminated isoimide oligomers were investigated as matrix resins which can produce high performance thermosetting polyimides and composites.
Herein, we present an innovative approach to generate a novel type of 3D optical nanostructures based on nanoporous anodic alumina (NAA), the so-called inverted nanoporous anodic alumina funnels (INAAFs). This electrochemical approach takes advantage of the differential dissolution rate of NAA with the annealing tempe…
Solution combustion generates mesoporous ceria with strongly anchored Ir nanoparticles, which are efficient methane reforming catalysts.
Lysine, a renewable resource from biomass fermentation, was converted to pure <italic>O</italic> -carboxyanhydride monomer, then well-defined polyester with amino groups was prepared <italic>via</italic> controlled ring-opening polymerization.
When a drop impacts a surface, a dimple can be formed due to the increased air pressure beneath the drop before it wets the surface. We employ a high-speed color interferometry technique to measure the evolution of the air layer profiles under millimeter-sized drops impacting hydrophobic micropatterned surfaces for im…
Chemical strain effects arising from the large size mismatch between the two A-site cations results in a lowering of the symmetry from polar <italic>R</italic> 3 <italic>c</italic> to a polar <italic>Cc</italic> in Bi <sub>0.95</sub> Dy <sub>0.05</sub> FeO <sub>3</sub> .
What are the lifetime and maximum length of a soap film pulled at a velocity V out of a bath of soapy solution? This is the question we explore in this article by performing systematic film rupture experiments. We show that the lifetime and maximal length of the films are fairly reproducible and controlled only by hyd…
The acid–base catalytic system based on N,N-dimethyl-4-aminopyridine (DMAP) and a protic acid that has already been revealed to be efficient for the ring-opening polymerization (ROP) of L-lactide in solution at room temperature was tested for the same polymerization in bulk at 100 °C. As observed in solution, the pres…
