In the present paper the use of Ni infiltration into preformed porous yttria-stabilized zirconia structures is investigated as a possible solution to the redox problem of Ni-based solid oxide fuel cell (SOFC) anodes and anode supports. It is shown that cermets containing Ni prepared by infiltration exhibited a conduct…
A smart role of the leaf margin makes the lotus surface dry when a lotus leaf floats on the water’s surface. It is mainly attributed to anisotropic topography composed of flat folds at the margin, which are quite different from the upper surface of the lotus leaf including the micro-papillae. The flat folds around the…
A new self-immolative dendritic probe directly detects triacetone triperoxide through amplification of a single cleavage event initiated by one molecule of hydrogen peroxide into multiple-release of fluorogenic end-groups.
A mathematical framework for the coupling of atomistic and continuum models by blending them over a subdomain subject to a constraint is developed. Using the framework, four classes of atomistic-to-continuum (AtC) blending methods are established, their consistency is studied, and their relative merits are discussed.…
Ligand exchanged gold quantum dots (GQDs) conjugated with cell-penetrating peptides are a new class of photoluminescent probes for nuclear targeting and intracellular imaging.
We present a new-type confine structure within 7.5 nm width dash-contact for sub 20 nm generation PRAMs. Phase change material (PCM) by chemical vapor deposition (CVD) was perfectly filled in a 7.5 nm width dash-contact without void along with 30 nm depth. By adopting confined CVD-PCM, we were able to reduce the reset…
In this study, ZnO thin films were deposited by atomic layer deposition (ALD) at various process temperatures. The purpose of this paper was to investigate the controllability of the preferred orientations of ZnO thin films by varying the process temperature and to determine the effect of the preferred orientations on…
The objective of this study is to achieve the enhanced delivery of 5-fluorouracil to brain through transferrin-coupled liposomes. 5-Fluorouracil-loaded liposomes were prepared by cast film method and characterized for particle size, shape, percent encapsulation efficiency and in vitro drug release. Biodistribution stu…
A series of intense green/yellow phosphors was synthesized by a high-temperature solid-state reaction. Their luminescent properties were characterized by means of powder diffuse reflection, photoluminescence excitation and emission spectra, and lifetime and temperature-dependent emission spectra in the temperature ran…
The use of an (18)O/(16)O exchange experiment as a means for probing surface space-charge layers in oxides is examined theoretically and experimentally. On the basis of a theoretical treatment, isotope penetration profiles are calculated for (18)O/(16)O exchange across a gas-solid interface and subsequent diffusion of…
Corrosion-resistant materials under atmospheric conditions can suffer from localized corrosion (e.g., pitting, crevice, stress-corrosion cracking). The stability of such a localized corrosion site requires that the site (anode) must dissolve at a sufficiently high rate to maintain the critical chemistry while a wetted…
Ferroelectric liquid crystal(FLC)has self-organized helical stuctures,which makes it have the charcter of one-dimension photonic crystal.When light propagates in FLC,the photonic band would emerge.Lasing in dye-doped FLC could occur at the edge of pseudo photonic band under excited by a pump beam,and lasing wavelength…
A readily recycled and regenerated heterogeneous catalyst of 9-thiourea epi-quinine supported on mesoporous silica exhibits enhanced enantioselectivity (up to 99.2%) in the asymmetric Friedel-Crafts reaction of imines with indoles.
The objective of the present study was to synthesize core-corona nanoparticles of doxorubicin (DOX) using hyaluronic acid-polyethyleneglycol-polycaprolactone (HA-PEG-PCL) copolymer for tumor targeting. Targeting efficiency of HA-PEG-PCL nanoparticles was compared with non-HA-containing nanoparticles (methoxy poly ethy…
Recently developed strategies and conditions to provide rational control of inorganic crystal growth via electrodeposition are presented with a specific focus on the systematic tuning of crystal habit and the regulation of branching growth. Precise morphology control is critical to investigate the effect that a materi…
Proton conducting oxides such as BaCe0.9Y0.1O3−δ have considerable promise for intermediate temperature fuel cells. Unfortunately these tend to be unstable, e.g. to attack by carbonation. Previous work has highlighted the possibility of utilising barium zirconate to provide a chemically stable electrolyte; however suc…
We report a novel strategy to synthesize nanofiber arrays of conducting polypyrrole with controlled lengths. Combining the merits of the electrochemical polymerization and the interfacial chemical polymerization, our biphasic electrochemical strategy can control the lengths of nanofibers from several hundred nanometre…
Nitrogen-doped CeO2 nanoparticles were synthesized through a wet-chemical route. Nitrogen has been successfully incorporated into CeO2 nanoparticles and the nitrogen-doping level was also successfully controlled. The optical properties due to the different N-doping levels in CeO2 nanoparticles were characterized by UV…
The anodic film generated in acid electrolytes on high-purity aluminum shows a porous morphology, formed by the packing of approximately hexagonal cells of alumina, containing a centrally located cylindrical pore. Conversely, during anodizing of an AA2024 T3 alloy, the presence of alloying elements, both in solid solu…
Monodispersed silver selenide (Ag2Se) nanoparticles have been prepared successfully by a hydrothermal reaction of AgNO3 with Na2SeSO3 in the presence of poly(vinyl pyrrolidone) (PVP) and KI at 180 °C for 20 h. TEM revealed that the nanoparticles are much like husked rice with lengths of about 60–80 nm and widths of ab…
