Young's equation describes the wetting phenomenon in terms of the contact angle between a liquid and a solid surface. However, the contact angle is not the only parameter that defines liquid–solid interactions, an additional parameter related to the adhesion between the liquid drop and the solid surface is also of imp…
Several cermet anode materials were investigated for direct internal reforming operation of solid oxide fuel cells. The effects of steam and discharge conditions were examined for internal reforming operation with propane as a hydrocarbon fuel. Even at high steam-to-carbon (S/C) ratio, power generation characteristics…
The dehydration behavior of caesium dihydrogen phosphate CsH2PO4 was investigated in the temperature range of 230 °C to 260 °C under high humidity, conditions of particular relevance to the operation of fuel cells based on this electrolyte. The onset temperature of dehydration was determined from changes in ionic cond…
Using the conducting polymer, polyaniline, as a prime example, this article highlights the important role of nucleation on the aggregation of nanoparticles. We demonstrate that during synthesis, irreversible aggregation of nanoparticles can be triggered by heterogeneous nucleation on pre-formed particles. Aggregation…
New robust functionalized nanohybrid materials were prepared by the interlayer covalent attachment of aminoalcohols to the octahedral sheets of kaolinite.
In this article, we will review the phenomena on circularly-polarized-light (CPL)-induced chirality in polymeric systems with photochromophores in their side-chain or main-chain. In the side-chain polymeric systems, the photoinduced chirality arises from superstructural chirality, i.e., helix structure, via aggregatin…
This paper proposes concrete enhancement of pyrolysis spray disposal performance. Solution to heat equation in particular cases of uniform and non-uniform fluid deposit is yielded as a guide to geometrical and temporal parameters control. Implemented models take into account simultaneously deposited material and targe…
A super-hydrophobic and highly transparent nanostructured film was fabricated via imprinting and conformally uniform chemical anchoring of poly(dimethylsiloxane) on a controlled nanoscopic dimension.
Calcium phosphate nanoparticles (nanoCaP) conjugated with cis-diamminedichloroplatinum (CDDP, cisplatin) were prepared through the electrostatic binding of an aquated species of cisplatin to the nanoCaP in a chloride-free solution. The agglomeration of the nanoCaP that typically occurs during synthesis of CaP was cont…
Reaction of LaCl(3) and dibenzoylmethane (Ph(2)acacH) in methanol with an excess of triethylamine resulted in the unexpected formation of a dodecanuclear hydroxo-bridged La cluster templated by CO(3)(2-) and phenylglyoxylate (Phgly), as determined by X-ray crystallography.
In this work we report on the synthesis and characterization of Au nanoparticles grown in the inner environment of cationic polyelectrolyte brushes. The nanocomposite synthesis relies on loading the macromolecular film with AuCl4− precursor ions followed by their in situ reduction to Au nanoparticles. We observed that…
A common phenolic antioxidant provides the ligand scaffold in the first discrete sodium-based catalyst for the highly active and controlled ring-opening polymerization of lactide.
The price of nickel is maintaining high level due to the demand continuing to outstrip supply, therefore the stainless steel, which is the largest consumer of nickel, has been maintaining a high-price.In this review, the way of nickel saving by more than half and the comparison of properties between the nickel saving…
Microbial polyhydroxyalkanoates (PHAs) have attracted research and commercial interests worldwide because they can be used as biodegradable thermoplastics and also because they can be produced from renewable resources. In order to compete commercially as commodity plastics, PHAs must fulfill certain standards such as…
AIM: To investigate the effect of chitooligosaccharides on proliferation of pancreatic islet cells, release of insulin and 2 h plasma glucose in streptozotocin-induced diabetic rats. METHODS: In vitro, the effect of chitooligosaccharides on proliferation of pancreatic islet cells and release of insulin was detected wi…
A portable fiber SERS probe has been developed based on Ag nanorod array fabricated by oblique angle deposition. The incoming laser beam was designed to focus onto the Raman substrate at 45 degrees incident angle in order to maximize surface enhanced Raman scattering signal. With a fiber Raman system, a detection sens…
One of the dominant characteristics of skin aging is loss of elasticity. Although the changes in the mechanical properties of the skin over several decades of life are substantial, objective measurements have failed to capture their magnitude thus far. Moreover, the mechanical properties of the skin are not uniform in…
We introduce a plasmon hybridization picture to understand the optical properties of double split-ring resonator metamaterials. The analysis is based on the calculated reflectance spectra from a finite-integration time-domain algorithm. Field distributions of the double split-ring resonators at the resonant frequencie…
Oleic acid (OA)-modified LaF3 : Er,Yb nanocrystals (NCs) have been prepared and investigated. The OA-capped nanocrystals have a nearly spherical shape with a mean diameter of 7 nm and show excellent dispersibility in common organic solvents and a PMMA matrix. A 0.25 g ml−1 transparent colloidal solution in toluene can…
During the last two decades, the total material input in Japan has been about 2 billion tons per year, and approximately 50%, i.e., about 1 billion tons, has accumulated as the net addition to stock in the form of buildings, social infrastructure, and various kinds of products. The amount of the net addition to stock…
