In order to investigate dye-dispersion behaviors in organic–inorganic hybrids, we incorporated RGB light-emitting organoboron dyes (1,3-diketonate BF2 complex, borondipyrromethene (BODIPY), and boron di(iso)indomethene as blue, green and red light-emitting dyes, respectively) into poly(2-hydroxyethyl methacylate) (PHE…
This paper reviews studies on dissolution, derivatization, and nanomaterial processing of chitin using an ionic liquid as useful media. Because chitin is the second most abundant polysaccharide on the earth after cellulose, there is major interest in conversion of native chitin resources into various useful materials…
CaWO4 and CaMoO4 doped with Dy3+ nanoparticles are obtained via an ethylene glycol route at temperature as low as 130 °C. The XRD results reveal that all the doped samples are well assigned to the scheelite structure of the CaWO4 and the CaMoO4 phase. Upon excitation by ultraviolet radiation, the CaWO4:Dy3+ and CaMoO4…
A series of multifunctional catalysts of three-dimensionally ordered macroporous (3DOM) ZrO2-supported core–shell structural Au@CeO2−δ nanoparticles were successfully synthesized by the one-pot method of gas bubbling-assisted membrane reduction–precipitation (GBMR/P). All the catalysts possess a well-defined 3DOM stru…
Two new ternary rare earth chalcogenides, Dy3GaS6 (1) and Y3GaS6 (2), are reported here. They both crystallize in the orthorhombic space group Cmc21 (no. 36). Both are synthesized in pure phase and show phase-matchable second harmonic generation (SHG) of about 0.2 and 0.5 times, respectively for 1 and 2, as strong as…
This paper investigates composite oxygen electrodes based on La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3−δ (LSCF) and Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3−δ (BSCF) for proton-conducting solid oxide electrolyzer using BaCe 0.5 Zr 0.3 Y 0.16 Zn 0.04 O 3−δ (BCZYZ) proton conductor. The conductivities of LSCF and BSCF are studied versus t…
In this work, we report on the self assembly behavior and stability studies of mixed amphiphilic nanosystems consisting of DPPC (dipalmitoylphosphatidylcholine) and poly(ethylene oxide)-b-poly(ε-caprolactone) (PEO-b-PCL) block copolymer in HPLC-grade water, phosphate buffer saline (PBS) and fetal bovine serum (FBS). T…
Carbon-based materials have been used quite successfully for decades within industry sectors. Especially, the application of them in the field of aerospace has been paid lots of attention. The severe environment such as γ-rays in space, which may give rise to the formation of atomic defects, may deteriorate the perfor…
The combination of nanotechnology and biology has developed into an emerging research area: nano-biotechnology. Upconversion nanoparticles (UCNPs) have attracted a great deal of attention in bioapplications due to their high chemical stability, low toxicity, and high signal-to-noise ratio. Magnetic nanoparticles (MNPs…
ZnO and Er‐doped ZnO with different molar ratios of Er/Zn were prepared using the homogeneous precipitation method. The photocatalysts prepared were characterized using scanning electron microscopy, transmission electron microscopy, X‐ray diffraction (XRD), UV‐vis spectroscopy, and photoluminescence spectroscopy. The…
Particle size control of colloidal mesoporous silica nanoparticles (CMPS) in a very wide range is quite significant for the design of CMPS toward various applications, such as catalysis and drug delivery. Various types of CMPS and their precursors (colloidal mesostructured silica nanoparticles (CMSS)) with different p…
BiAgSeS shows intrinsically low thermal conductivity in the temperature range from 300 K (∼0.46 W m−1 K−1) to 823 K (∼0.29 W m−1 K−1). Low thermal conductivity coupling with enhanced electrical transport properties achieved through partially substituting S2− by Cl− leads to a high ZT of ∼1.0 at 823 K for BiAgSeS0.97Cl…
Zinc sulfide (ZnS) thin films have been synthesized by spray pyrolysis at 310 °C using an aqueous solution of zinc chloride (ZnCl2) and thioacetamide (TAA). Highly crystalline films were obtained by applying TAA instead of thiourea (TU) as the sulfur source. X-ray diffraction (XRD) analyses show that the films prepare…
A novel photoelectrochemical sensor has been designed with polyaniline-reduced graphene oxide-titanium dioxide, which was further applied to sense gallic acid and exhibited extraordinary rapid response, high sensitivity and excellent anti-inference. Meanwhile, the mechanism has been elaborately explored.
Electrospinning usually results in the formation of scaffolds that are a few hundred microns in thickness with pore sizes in the micron range. However some applications, such as tissue engineering, necessitate the fabrication of cm-thick nanofibrous scaffolds with large pore sizes that allow for cell infiltration. Her…
Hierarchical copper nanowires (Cu NWs) having structures of rose-like stems with nano-thorns, with an average length and width of 6 ± 4 μm and 100 ± 15 nm, respectively, are prepared through a simple hydrothermal approach. In the presence of catechin, nano-thorn growth readily occurs from the side faces (200) of rose-…
We investigate the topological constraints (entanglements) in polymer–nanorod nanocomposites in comparison to polymer melts using dissipative particle dynamics (DPD) polymer model simulations. The nanorods have a radius smaller than the polymer radius of gyration and an aspect ratio of 7.5. We observe an increase in t…
In the current research a novel water based reaction scheme was developed to crosslink the protein from soy flour (SF) without using any external crosslinker. Soy flour, which contains about 55% protein and 32% carbohydrate and is the least expensive commercially available soy protein variety, was used for this resear…
The elastic response of vertically aligned-carbon nanotube/polydimethylsiloxane (A-CNT/PDMS) nanocomposites is presented in this study and related to the underlying aligned-CNT morphology. Multiwalled carbon nanotubes (MWCNTs) at 1% Vf are embedded in a flexible substrate of PDMS to create a flexible polymer nanocompo…
Y-doped BaZrO3 (BZY) is of the perovskite structure (ABO3), and is promising as an electrolyte in protonic ceramic fuel cells (PCFCs). However, factors limiting its protonic conductivity have not been clarified entirely, such as the unclear site occupancy of Y. In this work, X-ray diffraction patterns were collected u…
