Typically point defects are modeled by adding, removing, or exchanging at most few atoms around a given lattice site. We demonstrate the possibility of formation of extended antisite defects that involve complex, nonlocal atomic rearrangements, which cannot be captured within a simple point defect model. We illustrate…
Nanoemulsion-like polymer vesicles (polymersomes) having ionic liquid interiors dispersed in water are attractive for nanoreactor applications. In a previous study, we demonstrated that small molecules could pass through rubbery polybutadiene membranes on a time scale of seconds, which is practical for chemical transf…
Mechanism and curing kinetics of bisphenol A epoxy resin–iso-methyltetrahydrophthalic anhydride compositions using quaternary phosphonium salts as accelerators were investigated by differential scanning calorimetry (DSC) and electrospray mass-spectrometry (ESI-MS). The DSC method was applied to investigate curing kine…
Triggering factors, proposed mechanism and self-sustaining cycle for the crystallization of MSUM and gout.
TiO2, as one of the most promising photocatalysts, exists different phases such as anatase, rutile and brookite. These phases exhibit different properties and consequently different photocatalytic performances. In addition, mixed-phase TiO2Mixed-phase TiO have been demonstrated to have enhanced photocatalytic activity…
Zn-R1 exhibits reversible binding with acetate yielding different optical and fluorescence outputs on alternate addition of zinc and acetate ions.
Gallium nitride films were grown by hollow cathode plasma-assisted atomic layer deposition using triethylgallium and N2/H2 plasma. An optimized recipe for GaN film was developed, and the effect of substrate temperature was studied in both self-limiting growth window and thermal decomposition-limited growth region. Wit…
This work presents the synthesis of carbon nanotubes (CNTs) inside titania nanotube (TNTs) templates by a catalyst-free chemical vapor deposition (CVD) approach as composite platforms for photocatalytic applications. The nanotubular structure of TNTs prepared by electrochemical anodization provides a unique platform t…
Multiaxis 3D weaving technology allows insertion of in-plane fibres reinforcements, designated as bias yarns, oriented in directions other than 0° and 90° in the woven preform, unlike in the case of conventional weaving technology. By different existing weaving advanced techniques, two opposite bias yarn layers are fo…
This paper describes a comparison of surface roughness between ceramics and cubic boron nitride (CBN7020) cutting tools when machining of AISI H11 hot work steels treated at 50 HRC. Plan is designed according to Taguchi's L18 (2132) orthogonal array. The response surface methodology (RSM) and analysis of variance (ANO…
We successfully fabricated high-performance Al–Sn–Zn–O thin-film transistors (ATZO TFTs) with a quasi-double-channel (QDC) structure on glass by radio-frequency magnetron sputtering. The bilayer ATZO films are fabricated with different oxygen partial pressures during the sputtering process. The structure of the top AT…
The cyclocondensation reaction between rigid, electron-rich aromatic diamines and 1,1'-bis(2,4-dinitrophenyl)-4,4'-bipyridinium (Zincke) salts has been harnessed to produce a series of conjugated oligomers containing up to twelve aromatic/heterocyclic residues. These oligomers exhibit discrete, multiple redox processe…
Abstract There is no consensus about the rate and style of clay mineral diagenesis in progressively buried sandstones v. interbedded mudstones. The diagenetic evolution of interbedded Miocene sandstones and mudstones from the Vienna Basin (Austria) has therefore been compared using core-based studies, petrography, X-r…
Clinical long-term osteointegration of titanium-based biomedical devices is the main goal for both dental and orthopedical implants. Both the surface morphology and the possible functionalization of the implant surface are important points. In the last decade, following the success of nanostructured anodic porous alum…
Abstract The use of gold, silver, platinum and palladium for preparation of bimetallic nanoshells (AgAu, AgPt, and AgPdNSs, respectively) and their use for metallo‐ and bio‐metallo catalytic applications have been described. Bimetallic nanoshells (metallo‐catalysts) were employed for silane oxidation to silanols and h…
NiCu alloy nanoparticle-loaded carbon nanofibers (NiCuCNFs) were fabricated by a combination of electrospinning and carbonization methods. A series of characterizations, including SEM, TEM and XRD, were employed to study the NiCuCNFs. The as-prepared NiCuCNFs were then mixed with laccase (Lac) and Nafion to form a nov…
One of the best known hydraulic water distribution modeling toolkits that is most used by both researchers and practitioners is EPANET 2. Initially the authors aimed to speed up such simulations by utilizing modern multicore processors in the code implementation. The 30-year-old linear solver was replaced in steps by…
An operationally simple colorimetric method for measuring glutathione S -transferase (GST) activity was developed using cysteamine-capped gold nanoparticles (AuNPs) in this work. This method was based that GST can catalyze the reaction of 1-chloro-2,4-dinitrobenzene (CDNB) and glutathione (GSH) to produce a conjugate…
Abstract In thin and ultrathin supported films, the conformations of flexible linear polymer chains might be considerably confined, in particular, for film thicknesses smaller than a few times the radius of gyration. For ring polymers in solution or in melt, the radii of gyration are significantly reduced as compared…
Engineering whole organs from porcine decellularized extracellular matrix and human cells may lead to a plentiful source of implantable organs. Decontaminating the porcine decellularized extracellular matrix scaffolds is an essential step prior to introducing human cells. However, decontamination of whole porcine kidn…
