Point contact models for the effective thermal conductivity of porous media with uniform spherical inclusions have been briefly reviewed. The model of Zehner and Schlunder (1970) has been further validated with recent experimental data over a broad range of conductivity ratio from 8 to 1200 and over a range of solids…
1,3-Dihydro-1,3,3-trimethyl-8'-nitro-spiro[2H-indole-2,3'-[3H]naphth[2,1-b][1,4]oxazine] (SpO) is a photochromic, acidichromic and metallochromic compound. Its chromogenic properties are characterized in acetonitrile, at room temperature. They are exploited to process both boolean and Fuzzy logic. By using HClO(4), Al…
Cadmium sulfide (CdS) and cadmium selenide (CdSe) are deposited in situ onto mesoporous TiO2 films. The CdS/CdSe quantum dot (QD) co-sensitized photoelectrodes were used to fabricate all-solid-state quantum-dot-sensitized solar cells (QDSSCs) by using spiro-OMeTAD as a hole transport material (HTM). Two types of surfa…
Based on stepwise deposition of MOF films on a colloid crystal substrate, a strategy for fabricating photonic MOF films was developed. We found that the integration of a photonic structure endows MOF materials with unique optical properties, which can be used as a general and effective transduction scheme for a conven…
Redox active quadruply bonded units, M(2), can be combined so that they either (i) are bridged by an organic linker or (ii) function as a bridge between two identical organic ligands. When two M(2) units are linked together by an organic group that affords M(2)δ-bridge π-conjugation the electronic structure of each M(…
Hematite (α-Fe2O3) nanorods, nanotubes, and nanocubes were selectively synthesized via a hydrothermal process and subsequent calcination treatment. The nanorods showed higher catalytic activity than the nanotubes and the nanocubes for methane combustion and CO oxidation. It may be attributed to the highest occupancy o…
Nanoporous TiO(2) nanospheres with excellent visible light photocatalytic abilities and narrow pore size (11 ± 1 nm) distribution can be obtained via a rapid vapor assisted hydrolysis technique.
Ruthenium-indazole complexes are promising anticancer agents undergoing clinical trials. KP1339 is administered intravenously (i.v.), where serum proteins are the first available biological binding partners. In order to gain a better insight into the mode of action, mice were treated with different doses of KP1339 i.v…
Abstract — The strength activity index of mortar and microstructural characteristics of pastes containing treated palm oil fuel ash (POFA) have been investigated. POFA obtained from a palm oil mill was treated via sieving, grinding and heating at temperature of 450°C for 90 minutes in order to improve the pozzolanic r…
The first report concerning the cyclic performance of In2S3 nanosheets electrodes is presented here. These In2S3 nanosheets feature a high reversible capacity of 450 mA h g−1 under a large charging/discharging rate of ca. 1 C (700 mA g−1) after 40 cycles.
Bimetallic Pt–Rh nanoparticles can be deposited uniformly on surfaces of carboxylate functionalized multi-walled carbon nanotubes (MWNTs) using a simple one-step sonochemical method. The bimetallic nanoparticle catalyst exhibits a strong synergistic effect relative to the individual Pt or Rh metal nanoparticles for ca…
Nanostructures of boron nitride have attracted a great deal of interest due to their potential applications that comprise a broad range of topics, including biomedical technology, since it presents good chemical stability and suggests good biological inertia. This paper reports a facile and effective synthesis based o…
TiO2-supported Rh(0) nanoparticles were easily prepared in one step without calcination by a room temperature impregnation of the inorganic support with a prestabilized colloidal Rh(0) suspension. They are highly active and reusable catalysts for the hydrogenation of aromatics and chloroanisole derivatives in neat wat…
Chitin is the second most abundant polysaccharide in the world; it is found in insects, parasites and fungi. Chitinases break down chitin, and are a part of the defence mechanism against chitin-containing parasites in lower life forms. This review is based on the results of PubMed-searches using the search-terms: chit…
A series of square-planar Pt(II) complexes [Pt(C^N)(O^O)] (1–5) (C^N = 2-phenylpyridine, O^O denotes a series of β-diketonate ligands) is reported. Detailed studies of theoretical calculations, electrochemical and photophysical properties have shown that their excited states can be attributed to the mixing of 3MLCT, 3…
With the aim of facilitating the high performance printed In-Ga-Zn-O (IGZO) thin-film transistors (TFTs), we present the heretofore unrecognized chemical methodology for tailoring the chemical structures of printable IGZO semiconductors through incorporation of ethylene glycol in sol–gel derived precursor solutions. W…
An experimental setup for high-pressure liquid structure studies with synchrotron x-ray diffraction using the Paris-Edinburgh press has been installed at station 16-BM-B (HPCAT) of the Advanced Photon Source, Argonne National Laboratory. By collecting energy-dispersive data with a synchrotron white beam at various 2θ…
The surface-modified zinc phosphate (Zn3(PO4)2) nanocrystals were synthesized by a facile and efficient one-step ultrasonic-template-microwave (UTM) assisted route. The crystal structure, optical properties and morphologies of zinc phosphate nanocrystals were characterized by X-ray diffraction, Fourier transform infra…
In high strength 6000 series alloys dispersoids that form during heating to the homogenization temperature are used to improve fracture toughness and suppress grain growth during the extrusion process. However, these dispersoids can act as heterogeneous nucleation sites for non-hardening Mg-Si precipitates if quenchin…
We demonstrate a facile, one-step, protein-directed approach to preparing a new functional reduced graphene oxide via simultaneous reduction and surface functionalization of graphene oxide sheets with herceptin and show its potential application as a novel biological imaging agent.
