Hemicelluloses are among the most abundant renewable polymers in nature, and their processing into biodegradable polymeric materials via extrusion was recently reported as a novel alternative technique for solvent casting. A simple heat-treatment step conducted after the extrusion of corn cob xylans was found to enhan…
This Article reports the syntheses, structural characterization, and magnetic studies of four different Cu(II)-azido compounds based on imidazole or substituted imidazole ligand. The compounds, [Cu2(μ1,1-N3)2(EtimiH)4(ClO4)2] (1) (EtimiH = 2-ethylimidazole), [Cu2(μ-Meimi(-))(MeimiH)2(μ1,1-N3)2(μ1,3-N3)]n (2) (MeimiH =…
We present the fundamental principle of plasmonic-graded-index materials for radiating and guiding at infrared range. The method to derive effective refractive index is presented and effective refractive index engineering is comprehensively investigated by obtaining complex dispersion diagrams. As an illustrative exam…
A comparative, temperature‐dependent (80–500 K at 5 K intervals), micro‐Raman spectroscopic study of 300 and 50 nm diameter ceramic BaTiO 3 nanoparticles was carried out with the purpose of elucidating the nanoparticle size effect on the temperature dependence of the polar and non‐polar phonons. A method for calibrati…
The peroxo ligand is one of the most promising structure-directing agents in TiO 2 nanocatalyst synthesis; however, its role in nanocatalyst growth and polymorph control is not well understood. Using a combination of scanning tunneling microscopy, X-ray photoemission spectroscopy, and kinetic Monte Carlo simulation, w…
Dispersibility and stability of chemical functionalized multi-walled carbon nanotubes (f MWCNTs) in aqueous solution by using small amount of a cationic ionic liquid (IL), 1- tetradecyl-3-methylimidazolium Chloride, [C14mim]Cl, was investigated and was compared with unfunctionalized MWNTs. The surface modification of…
Metal hydrides with high thermodynamic stability are desirable for high-temperature applications, such as those that require high hydrogen release temperatures or low hydrogen overpressures. First-principles calculations have been used previously to identify complex transition metal hydrides (CTMHs) for high temperatu…
Magnesium phosphate chemically bonded ceramics attracted much attention because of its good biocompatibility. In this work, curing behavior and microstructure of magnesium phosphate chemically bonded ceramics with different MgO to KH 2 PO 4 ratios were investigated. The results showed that the setting time decreased a…
The strongly temperature‐dependent ionic mobility in polymer electrolytes is used to “freeze in” specific ionic charge environments around a nanowire using a local wrap‐gate geometry. This makes it possible to set both the threshold voltage for a conventional doped substrate gate and the local disorder potential at te…
Nowadays, one-phase and full-color phosphors have gained increasing interest. Here, we show that Mn-activated zinc gallogermanate, Zn1+xGa2-2xGexO4: Mn, x = 0 ~1, phosphors exhibit a broadly tunable luminescence from green to deep red with the substitution of Ga3+ by Ge4+. The green and deep red emissions are attribut…
Two novel organic-inorganic hybrids, Na[PMo(V)8Mo(VI)4O38(OH)2Zn4][pyim]2·1.5H2O [ε(pyim)2] (pyim = 2-(2-pyridyl)-imidazole) and [PMo(V)8Mo(VI)4O37(OH)3Zn4]2[pyim]6·4H2O [ε2(pyim)6], based on ε-Zn Keggin units {ε-PMo(V)8Mo(VI)4O(40-x)(OH)(x)Zn4}, have been successfully synthesized under hydrothermal conditions by cont…
Glasses are very versatile materials, also because of the ease of doping them with various elements and compounds. In particular, rare-earth-doped glasses have greatly contributed to the development of optical amplifiers, lasers, active optical waveguides and white-light-emitting devices. White light emitting diodes (…
Amorphization of cellulose by swelling in ionic liquid (IL)/water mixtures at room temperature is a suitable alternative to the dissolution-precipitation pretreatment known to facilitate enzymatic digestion. When soaking microcrystalline cellulose in the IL 1-ethyl-3-methylimidazolium acetate containing 20 wt % water,…
Authors have studied the interaction between high-melting compounds from various classes, such as transition-metal carbides, borides, nitrides, and silicides, and covalent-bonded B 4 C, SiC, Si 3 N 4 , AlN etc. (over 160 phase diagrams), ternary B 4 C-SiC-Me d B 2 , SiC-TiC-TiB 2 and other eutectics, which is importan…
In this study, chitosan/polyvinyl alcohol binary and tannic acid/chitosan/polyvinyl alcohol ternary composite nanofiber membranes from chitosan citric acid salt aqueous solutions without the use of toxic solvents through Forcespinning ® technology were successfully mass produced. Chitosan is being widely evaluated as…
Mechanically straining graphene opens the possibility to exploit new properties linked to the stressed lattice of this two-dimensional material. In particular, theoretical analyses have forecast that straining graphene by more than 10% is a requirement for many novel applications that have not yet been experimentally…
An efficient method for processing superhydrophobic surface is presented in this paper, which can realise the microstructure machining on a large area. First, the microgroove arrays were processed by high speed precision micromilling machine on the surface of the aluminium alloy. Then, the surface of the microgroove w…

Monodispersed yttrium aluminum garnet (YAG) crystallites with well-developed and controllable crystal faces were obtained by the solvothermal method. The effects of temperature, time, and solvents on the phase formation, morphology, and particle size distribution were investigated. YAG can be obtained at relatively lo…
Blends of poly(vinyl alcohol) (PVA), polyethyleneimine (PEI), and graphene oxide (GO) were prepared by solution casting method. Calorimetric thermal properties of the blends were investigated. The <TEX>$T_gs$</TEX> of PVA/PEI blends were higher than the <TEX>$T_gs$</TEX> of either of the component polymers at low conc…
