As a fundamental study for clarifying the reduction phenomena of sintered ore in a blast furnace, mixtures of iron oxide and quaternary calcium ferrite (Cf) were prepared and its kinetic behavior at the final stage of reduction with CO gas was studied. Reduction rate increased with increasing reduction temperature reg…
Stimuli-responsive degradation of amphiphilic block copolymer (ABP) micelles is highly desired in the development of multifunctional nanomaterials. For polymer-based drug delivery applications, the degradation enables fast and controlled release of encapsulated therapeutics from the delivery vehicles in targeted cells…
A model is discussed which describes the generation of X-rays in conventional tubes using tabulated bremsstrahlung energy spectra depending on three variables: the target atomic number, the incident electron kinetic energy, and the fraction of energy radiated. Additionally a parameter-free description of the character…
This chapter reviews the main topics related to starch in polymers technology taking into account all the different forms in which starch can appear (native, gelatinized, retrograded, destructurized, complexed) giving more details for those which are related to starch-based polymers. Without intention of a whole starc…
Incorporation of nanoparticles into a polymer can result in enhancement of electrical, thermal and mechanical properties, particularly at high temperatures where the polymer alone might exhibit softening or degradation. The nanocomposite softening temperature may or may not coincide with the temperature at which the n…
this study examined the phytochemical composition and antiinflammatory activity of methanolic extracts of Cimicifuga racemosa roots and Mimosa pudica seeds. the antiinflammatory effect was assessed using the carrageenan-induced paw oedema model in Wistar rats. Indomethacin (20 mg/kg PO) was used as a positive control…
Fe based metallic glassy alloys are prospective material for micro parts due to their excellent mechanical properties. In this study we successfully prepared two kinds of [(FeXCo1−X)0.75Si0.05B0.2]96Nb4 (X=0.5 and 0.8) alloy mono-sized spherical particles with various sizes as a raw material for the micro parts by usi…
Antifouling properties of a traditional material, polyacrylamide, were evaluated comprehensively in this work to answer two questions: 1. Can polyacrylamide achieve ultralow fouling surfaces (< 50 pg/mm 2 protein adsorption)? 2. How robust is the antifouling ability of the polyacrylamide coating when the environment f…
Heat from radionuclide decay causes coupled thermal (T), hydrological (H), chemical (C), and mechanical (M) processes in the rock mass. These coupled processes impact the ability of a repository to isolate waste by affecting water seepage into waste-emplacement drifts and by affecting radionuclide transport. The U.S.…
Metallic nanoparticles (NPs) and semiconductor quantum dots (QDs) exhibit unique photophysical, electronic and catalytic properties. The present article summarizes several paradigms developed in our laboratory for the use of semiconductor QDs and metal NPs for the in vitro and intracellular bioanalytical applications.…
The potential of semifluorinated polymers thin nanocomposite films to form responsive interfaces is demonstrated. The changes that take place in a random copolymer Biphenyl Perfluorocyclobutane (BPh-PFCB) impregnated with Polyhedral Oligomeric Silsesquioxane (POSS) nanoparticles (NPs) exposed to humidity were followed…
Nowadays, the utilization of raw materials derived from renewable feedstock is in the spotlight of the chemical industry. Vegetable oils are an important platform chemicals due to their universal availability, inherent biodegradability and low price. Taking into account that polyurethanes are one of the most versatile…
The Gd-based amorphous/nanocrystal composite is prepared by controlling the cooling rate and the element ratio. The X-ray diffraction, differential scanning calorimeter and atomic force microscope/magnetic force microscope are used to confirm the composite microstructures from different perspectives. The magnetic test…
Titanium dioxide was widely used as photocatalyst for organic pollution degradation. Many researchers have reported that Ti0 2 is one of the most active catalyst in pesticides, phenols and the degradation of dyes. In this study, silver doped Ti02 nanoparticles (Ti0 2 -Ag) was succesfully prepared via sol-gel method an…
We investigate the optical characteristics of the tunable laser of a one-dimensional photonic crystal (1D PC) containing Dye-doped nematic liquid crystal (NLC). The dielectric multilayer consisting of an alternating stack of SiO2 and TiO2 layers is used as the 1D PC whose defect layer is filled with the laser dye and…
In this paper, we propose an improved shunt-capacitance-aided composite right/left-handed (CRLH) leaky wave antenna (LWA) with large beam-scanning-range (BSR)/bandwidth ratio based on substrate integrated waveguide (SIW) structure. The CRLH LWA is constructed by etching interdigital capacitor on the waveguide surface,…
The runtime performance of the popular biopolymer molecular dynamics simulation packages AMBER, CHARMM, GROMACS, LAMMPS and NAMD have been investigated in an extensive benchmark study on the hardware platforms Cray XE6/Interlagos, IBM iDataPlex and BlueGene/P. Five dierent protein and protein/membrane systems in the r…
This work has been focused on a cellulose pretreatment process using l-methyl-3-methylimidazolium dimethylphosphate ([DMIM]DMP) for subsequent hydrolysis over cellulase. Different operational variables (the amount of [DMIM]DMP, the pretreatment temperature, the pretreatment period) affecting the pretreatment were inve…
Chitin is the next most abundant natural polysaccharide after cellulose. It can be found in shells of shrimps, crabs and crayfish, which are waste products in food industry. Chitosan is becoming popular in an increasing number of industrial applications due to its availability, low cost and biodegradability. Many of t…
Quantum dots (QDs) are semiconductor nanocrystals with unique photo-physical properties. QDs are brightly fluorescent and photostable, and therefore represent a novel class of fluorescence probes for bio-imaging and cell monitoring. There are different techniques for labeling cells with QDs. Moreover, there is evidenc…
