In this paper, we study the effect of magnetic disc arrays on the self-assembly of ferrofluid droplets. By inducing magnetic hydrodynamic instability, we are able to realize the fission of a large ferrofluid droplet into a highly uniform droplet lattice structure under the influence of the magnetic disc array. We have…
Using the transfer matrix method approach (TMM), the present paper attempts to determine the optical properties of quasi-periodic symmetric one-dimensional photonic systems. In addition, it studies hybrid hetero-structure systems constructed by using periodic and quasi-periodic multilayer systems. The effect of symmet…
Since the discovery of photocatalytic splitting of water on TiO 2 electrodes in 1972 by Honda and Fujishima, a great deal of effort has been devoted in recent years to the development of highly active heterogeneous photocatalysts for environmental applications including air purification, water disinfection, hazardous…
Low temperature (200°C) direct bonding of InP and Si 3 N 4 coated silicon wafers using oxygen plasma surface treatment has been demonstrated, which transfers InP-based thin films onto Si substrates for heterogeneous photonic integration. Pulling test shows a high bonding energy comparable to the InP fracture energy. T…
40Gbps Small form factor thin film polymer on silicon (TFPS) EO modulators have been presented. The TFPS modulators have a small size, low Vπ, broad bandwidth and zero chirp, which are desirable for telecom applications.
Commercial titanium dioxide nanomaterials were found to be active in selective photocatalytic oxidation of ammonia to dinitrogen (photo-NH3-SCO). Photoactivated conversion of 1000 ppm ammonia in simulated air with high selectivity for dinitrogen was achieved over a thin layer of TiO2 in a flow reactor at 150 °C, 300 h…
SkePU is a skeleton programming framework for multicore CPU and multi-GPU systems. StarPU is a runtime system that provides dynamic scheduling and memory management support for heterogeneous, accelerator-based systems.
Polycrystalline thin films of CuGaSe 2 -related Cu-deficient materials were prepared by vacuum co-evaporation. The composition was adjusted in order to prepare copper gallium selenide, abbreviated as CGSe, with an optimal band gap and valence band maximum position for photoelectrochemical water splitting. The effect o…
In a previous paper [E. O. D. Andriantiana, MATCH Commun. Math Comput. Chem. 68 (2012) 000–000] trees with a fixed number n of vertices were ordered according to their energy, and a large number of trees with greatest energy were characterized. These results, however, hold only if n is large enough. We now analyze the…
In this work, the enhancement in photonic band gap (PBG) in a dielectric-semiconductor photonic crystal (DS PC) is investigated. We consider two possible schemes that can be used to enhance the PBG in the near-infrared region. The first scheme is to add an ultrathin metal layer into the DS PC such that a structure of…
A bromide ion directed double stranded helicate is synthesised and its structure is reported for the first time. Synthesis of a series of β-aminocarbonyls using this water soluble helicate as a catalyst for a three-component amionalkylation reaction is also explored by adopting solvent-free reaction conditions.
In the present work, we report for the first time the growth of uniform single crystalline In2Te3 nanowires via the chemical vapor deposition (CVD) method. The CVD grown In2Te3 nanowires are single crystals along [132] growth direction with a uniform diameter of around 150 nm and an average length of tens of microns.…
A new energy transformation concept based on carbon recycling, called the Active Carbon Recycling Energy System, ACRES, had been proposed for a zero carbon dioxide emission process. A smart ironmaking system based on ACRES (iACRES) was discussed thermodynamically. Efficient regeneration of carbon material from carbon…
For high volume manufacturing (HVM) using extreme ultraviolet (EUV) lithography, a practical resist outgassing qualification system is required. Witness sample (WS) testing systems using electron beam (EB) or low power EUV have been proposed as candidate methods, however some issues remain on how these alternative lig…
Radiation safety education/training is essential and is associated with a reduction in the radiation dose to both patients and staff. We used a questionnaire to assess the level of radiation safety knowledge among nurses working at Tohoku Kosei-Nenkin Hospital. Some nurses were also interviewed. The results of our stu…

Resonant X-ray Emission Spectroscopy (RXES) is used to characterize the ligand field states of the prototypic self-assembled square-planar complex, [Pt(tpy)Cl]Cl (tpy=2,2':6',2''-terpyridine), and determine the effect of weak metal-metal and π-π interactions on their energy.
We report on the development of a fully operational atomic layer deposition (ALD) system. This system is computer controlled and can deposit multilayered systems without user intervention. We describe the design of manifold, reaction chamber and exhaust. Additionally we give some features of the automatization softwar…

Core-functionalized star polymers were designed as functional compartments for molecular recognition and catalysis, focused on the unique environments of the microgel-cores that were spatially separated from outer environments by the surrounding linear arms. Due to the high tolerance to functional groups and the high…
