We investigate the exciton energy transfer (ET) in nanoassemblies (nanotube based aggregates) formed by polymer wrapped single-walled carbon nanotubes (SWNTs) using photoluminescence (PL) spectroscopy and simulation. The distinctive feature of this study is the gradual growth of such nanostructures in aqueous medium i…
Microsolvated clusters of gold chloride are probed by electrospray ionization mass spectrometry (ESI-MS) and scalar relativistic electronic structure calculations. Electrospray ionization of aqueous AuCl3 leads to mononuclear clusters of types [AuCl2](+)(H2O)n (n = 0-4), [AuOHCl](+)(H2O)n (n = 0-1) and [AuCl2](+)(HCl)…
Role of Ceria-Zirconia Solid Solution with High Oxygen Storage Capacity in Cermet Anodes of Solid Oxide Fuel Cells, Lee, Sung-Il, Choi, Moon-Bong, Dasari, Hari Prasad, Hong, Jongsup, Kim, Hyoungchul, Son, Ji-Won, Lee, Jong-Ho, Kim, Byung-Kook, Je, Hae-June, Yoon, Kyung Joong
Millimeter-long and micrometer-wide single-crystal β-AgVO 3 microribbons are synthesized and transformed into highly SERS-active one-dimensional materials.
An octacarboxy-silsesquioxane was designed and synthesised through a multiple-step regioselective reaction. This novel hybrid inorganic-organic compound presents highly attractive features for application as a building block, as it has a robust, rigid structure and a high number of carboxylic coordination sites organi…
We investigated a two‐step method to deposit the ZnO‐based nanostructure films, including nanorods and nanoflowers. In the first step, sputtering method was used to deposit the ZnO films on SiO2/Si substrates as the seed layer. In the second step, Zn(NO3)2–6H2O and C6H12N4 were used as precursors and hydrothermal proc…
X-ray diffraction rocking-curve measurements were performed on tetragonal hen egg white (HEW) lysozyme crystals grown with and without the application of an external alternating current (AC) electric field. The crystal quality was assessed by the full width at half maximum (FWHM) value for each rocking curve. For two-…
The paper presents the 0D models of selected auxiliary equipment of Solid Oxide Fuel/Electrolysis Cell hydrogen peak power plant, i.e., hydrogen compressor, high temperature heat exchanger, and a water pump, which has been calibrated to the appropriate available experimental data. Based on a sensitivity analysis the g…
In the present work we explore via first-principles simulations whether the ligand/cluster/support catalytic complex generated by CO oxidation over silver trimers deposited on the regular MgO(100) surface - i.e. a Ag3/carbonate or Ag3(CO3)/MgO(100) species - can be used as a catalyst in a different reaction: the selec…
A new rational approach to the dispersion of SWCNT in aqueous media with amphiphilic RAFT block copolymers is proposed.
Los embalses Cabra Corral y El Tunal de la cuenca del Juramento (ACJ), constituyen los reservorios de mayor relevancia de la provincia de Salta (Argentina). Se analizó la composición y estructura del fitoplancton en ambas presas en febrero, mayo y octubre en el período 1998-2011, utilizando técnicas normalizadas. El i…
In this study, the microstructure and mechanical properties of Cu–40Zn brass alloy with 0.5 mass% Cr additives produced by powder metallurgy (P/M) process were investigated. Cu–40Zn–0.5Cr and Cu–40Zn brass powders were made by water-atomization process, and used as raw materials. These powders were consolidated by hot…
The purpose of this research is to create nano particles rice rusk ash used as a filler in thermoplastic high density poliethylen (HDPE) and nano-mechanical properties of the resulting composites.The method of rice husk ash made way smoothed by ball mill PM 200 for 1 hour, the filter results in a ball mill with a siev…
Residual clay deposits overlying Precambrian Basement Complex situated at Orin, Igbara Odo, Ikere and Ado Ekiti were investigated using several analytical techniques. Field evidence supported by mineralogical and physicochemical analyses suggests that the kaolinitic clay deposits is a product of hydrothermal and in-si…
スギを用いて製造したクロス・ラミネイティド・ティンバー（CLT）について，積層数，ラミナ構成，加圧板の方向に対する外層ラミナの方向，荷重方向に対する試験体の配置を変化させてめり込み試験を行い，各組み合わせによるCLTのめり込み強度性能を明らかにするとともに，めり込み強度性能を簡便に評価する方法を検討した。めり込み試験の結果，めり込み強度性能を決定づけるパラメータは，外層ラミナの方向と試験体の配置であり，積層数やラミナ構成はめり込み強度性能にはあまり寄与しないことがわかった。各ラミナの比例限度応力を用いて，CLTの比例限度応力を推定したところ，推定値と実測値は比較的よく一致した。
Large quantities of agricultural waste are generated daily, and their safe disposal raised much global concern. The popular trends in the stabilization or modification of construction materials, especially soil, have resulted in innovative techniques of utilizing the solid waste materials. This paper presents an exper…
Composites of pineapple fibre (PAF) with High Density Polyethylene (HDPE) were produced using the injection molding machine. The maximum amount of PAF accepted by HDPE was observed to be 50% of the HDPE weight. The composites were subjected to tests to evaluate their physical and mechanical properties. The density was…
The first step in many mining operations is blasting, and the purpose of blasting is to fragment the rock mass in the most efficient way for that mine site and the material end use. Over time, new developments to any industry occur, and design and implementation of traditional techniques have to change as a consequenc…
The photocatalytic potential of a derivative family of the unique Keplerate type nanoporous Mo–O based polyoxometalates has been evaluated.
High grade gliomas are some of the deadliest human tumours. Conventional treatments such as surgery, radiotherapy and chemotherapy have only a limited effect. Nowadays, resection is the common treatment of choice and although new approaches, such as perioperative magnetic resonance imaging or fluorescent microscopy ha…
