Quantitative evaluation of oxidation behavior of high‐temperature materials is imperative for applications in a Silicon carbide ( SiC )‐based thermal protection system ( TPS ) of reentry space vehicles. However, the reported oxidation rates obtained using thermogravimetric analysis ( TGA ) have been widely varied amon…
The binding of (E)-2-(acetamidomethylene)succinate (E-2AMS) to E-2AMS hydrolase is crucial for biological function of the enzyme and the last step reaction of vitamin B(6) biological degradation. In the present study, several molecular simulation methods, including molecular docking, conventional molecular dynamics (M…
Nanocrystalline tetragonal zirconia is commercially very significant material which finds extensive use as an anode material in SOFCs, as a catalyst oxygen sensor and structural material. Nanocrystalline zirconia powders for high performance anode of SOFCs have been synthesized by co-precipitation route. This techniqu…
We demonstrate laser-driven microflow-induced orientational change (homeotropic to planar) in a dye-doped nematic liquid crystal. The homeotropic to planar director alignment is achieved in unrubbed cells in the thermal hysteresis range of a discontinuous anchoring reorientation transition due to the local heating by…
Fiber diameter and its distribution are the fundamental parameters affecting the performance of melt-blown nonwoven materials. This paper proposes a new method to measure diameters of microfiber in nonwoven based on image processing techniques. The one-pixel-wide boundaries of potential fibers were extracted first. Th…
Article Applicability of Degradable Magnesium LAE442 Alloy Plate-Screw-Systems in a Rabbit Model was published on September 7, 2013 in the journal Biomedical Engineering / Biomedizinische Technik (volume 58, issue SI-1-Track-C).
The catalytic activity of low-percentage Co,Pd systems on ZSM-5, ERI, SiO 2 , and Al 2 O 3 supports in the oxidation of CO was studied. The activity of bimetal-containing catalysts was shown to depend on the nature of the catalyst and the amount and ratio of their active components. According to the results of thermop…
The ordering of a chiral block copolymer (BCP*) polystyrene- b -poly( d -lactide) during the solvent-casting process was studied in real time using in situ small-angle X-ray scattering (SAXS) and wide-angle X-ray diffraction (WAXD) simultaneously. Three different solvents, namely benzene, dimethylformamide, and 1,3-di…
The effect of Li promoter on the catalytic performance of the activated carbon (AC) supported cobalt catalysts (Co/AC) for CO hydrogenation was investigated by means of CO hydrogenation, X-ray diffraction (XRD), temperature-programmed reduction (H-2-TPR), and temperature-programmed desorption of adsorbed CO (CO-TPD).…
Congo red dye as well as other eagerly self-assembling organic molecules which form rod-like or ribbon-like supramolecular structures in water solutions, appears to represent a new class of protein ligands with possible wide-ranging medical applications. Such molecules associate with proteins as integral clusters and…
Fluorescent silica nanoparticles (FSNPs) can provide high-intensity and photostable fluorescent signals as a probe for biomedical analysis. In this study, FSNPs hybridized with aggregation-induced emission (AIE) luminogens (namely FSNP-SD) were successfully fabricated by a surfactant-free sol-gel method. The FSNP-SD w…
Anisotropy effects for spin avalanches in crystals of nanomagnets are studied theoretically with the external magnetic field applied at an arbitrary angle to the easy axis. Starting with the Hamiltonian for a single nanomagnet in the crystal, two essential quantities characterizing spin avalanches are calculated: the…
Organically modified silica compounds (ORMOSILs) were synthesized by a sol-gel method from amine-functionalized 3-aminopropyl triethoxylsilane and tetramethylorthosilicate and were doped in situ with LaF3:Ce nanoparticles, which in turn were prepared either in water or in ethanol. Doped ORMOSILs display strong photolu…
Brazilian market for wood panels is expanding. Among the types of produced panels, particleboards deserve, being MDP panel the main product. MDP means Medium Density Particleboard that is a lignocellulosic composite made with matrix of synthetic adhesive (urea formaldehyde resin) and reinforcement phase of particles o…
This paper investigated the effect of chromium underlayer on the structure, microstructure, and composition of the nano-crystalline diamond films. Nano-crystalline diamond thin films were deposited at high temperature in microwave-induced plasma diluted with nitrogen, on single crystal silicon substrate with a thin fi…
Article A Novel Magnetic Field Device for Inducing Hyperthermia Using Magnetic Nanoparticles was published on September 7, 2013 in the journal Biomedical Engineering / Biomedizinische Technik (volume 58, issue SI-1-Track-E).
Abstract The results of first‐principles calculations of the electronic structure of a spin‐frustrated V 15 cluster with the use of a generalized density functional scheme that allows non‐collinear spin configurations are presented. By using the results of these calculations, it was possible to determine a Heisenberg–…
In this study, we have constructed a simple, sensitive and rapid biosensor for detection of acetylcholine esterase (AChE) based on CdTe quantum dots (QDs). The detection limit of AChE by one-step enzyme reaction based on the thiolglycolic acid (TGA) stabilized QDs (TGA-QDs) was 10 U/L and the linear range was 10–100 a…
A series of main-chain poly(amide-triazole)s were prepared by copper(I)-catalyzed alkyne-azide AABB-type copolymerizatons between five structurally similar diacetylenes 1-5 with the same diazide 6. The acetylene units in monomers 1-5 possessed different degrees of conformational flexibility due to the different number…
Signatures of glassy dynamics have been identified experimentally for a rich variety of materials in which molecular networks provide rigidity. Here we present a theoretical framework to study the glassy behavior of both passive and active network materials. We construct a general microscopic network model that incorp…
