Atrazine (ATZ) has been used extensively as an herbicide, mainly due to its relatively low cost and ease of application. Previous studies have shown that many pollutants are redox active being able to enter microorganisms, causing a univalent reduction of dioxygen with reactive oxygen species (ROS) formation. These pr…
Continuing from Part I (Christensen, 2014, “Failure Mechanics—Part I: The Coordination Between Elasticity Theory and Failure Theory for all Isotropic Materials,” ASME J. Appl. Mech., 81(8), p. 081001), the relationship between elastic energy and failure specification is further developed. Part I established the coordi…
ABSTRACT Multiwall Carbon Nanotubes (MWCNT) with an elevated aspect ratio were chemically functionalized with amines and two types of epoxide groups. Thermogravimetric analysis and Fourier Transform‐Infrared Spectroscopy (FTIR) analysis corroborated that the functionalization degree was substantial (up to 30 wt %) and…
Many advanced manufacturing processes employ scanning electron microscopes (SEM) for on-line critical measurements for process and quality control. This is the third of a series of papers discussing various causes of measurement uncertainty in scanned particle beam instruments, and some of the solutions researched and…
Expanded clay concrete differs from heavy-weight concrete not only by the composition and performance properties, but also by modes of chemical interactions between the components. So, not the primary problem of reinforcement corrosion in heavy-weight concrete under the normal conditions and the correct protective lay…
Mesoporous alumina was synthesized by hydrothermal method at 150 °C for 6–24 h using tetramethyl urea followed by their calcination at 500–1100 °C. The samples were characterized by XRD, FTIR, N2 adsorption–desorption, FESEM and TEM. The γ-Al2O3 was found to be stable up to 1000 °C for the samples prepared at 150 °C/6…
Sb doped ZnO thin films having various thicknesses have been prepared onto glass substrate by using thermal evaporation method. The atomic compositions of the grown films have been determined by Energy Dispersive Analysis of X-ray (EDAX) method. The optical properties were measured by using a UV-VIS-NIR spectrophotome…
The objective of this effort is to synthesize and characterize a series of lanthanum‐(La) doped Sr 2 MgMoO 6 ( SMMO ) and La‐doped Sr 2 MgNbO 6 ( SMNO ) anode materials which can be used in combination with lanthanum‐containing electrolytes to mitigate the effects of lanthanum poisoning in solid oxide fuel cells ( SOF…
Scanning Microwave Impedance Microscopy (sMIM), a new electrical measurement mode for AFM, has shown significant success in the imaging and characterization of electrical properties at 10's of nm length scales. We review the state of the art, including imaging studies revealing electrical characteristics of novel mate…
For decades, attempts have been made to understand the formation of colloidal glasses and gels by linking suspension mechanics to particle properties where details of size, shape, and spatial dependencies of pair potentials present a bewildering array of variables that can be manipulated to achieve observed properties…
Gold nanoparticles (AuNPs) with small particle size have been difficult to be synthesized due to their strong agglomeration. Herein we report that the nanochannels of mesoporous silica synthesized from template sol-gel synthesis were utilized to prepare AuNPs by employing thermal hydrogen reduction. Mesoporous silica…
The interaction between carbon and BN nanotubes (NT) and transition metal Co and Ni supports was studied using electronic structure calculations. Several configurations of interfaces were considered, and the most stable ones were used for electronic structure analysis. All NT/Co interfaces were found to be more energe…
ABSTRACT To modify the mechanical properties of a poly(l‐lactide) (PLLA)/poly(para‐dioxanone) (PPDO) 85/15 blend, poly(para‐dioxanone‐co‐l‐lactide) (PDOLLA) was used as a compatibilizer. The 85/15 PLLA/PPDO blends containing 1–5 wt % of the random copolymer PDOLLA were prepared by solution coprecipitation. Then, the t…
This paper addresses a current debate about the morphology of M7C3 phase in the chrome carbide overlay (CCO) and white iron community. This morphology was investigated using a serial sectioning technique in combination with computer post-processing software. A 600×600×300 μm volume of CCO was reconstructed in three di…
The present work reports the electrical conductivity for Nb-doped TiO 2 single crystal at elevated temperatures (1223 K–1298 k) in the gas phase of controlled oxygen activity [10 −10 Pa < p(O 2 ) < 10 Pa]. The effect of oxygen activity on the electrical conductivity is considered in terms of defect disorder of TiO 2 a…
We report a simple technique for the fabrication of dots-on-spheres (DoS) structures in which conjugated polymer dots (CPdots) are immobilized on the surface of silica spheres via charged interaction. Red-, green-, and blue-emissive conjugated polymers were synthesized and employed to validate the feasibility of an ap…
The knowledge of pitting corrosion behaviour of stainless steel is a critical factor in material science. In order to develop an automatic system to study pitting corrosion behaviour of this material, models based on support vector machines (SVMs) and k-nearest neighbour are presented in this work. The influence of th…
Coexistence of smectic and nematic orders in 3D curvaceous bicontineous cubic or hexagonal hierarchical structures is observed in a novel class of nanophase separated, flexible double liquid crystalline (LC) diblock copolymers of different molecular weights (MWs) but similar compositions, obtained via sequential anion…
Abstract In order to obtain flame retardants with good heat resistance, retardant properties and affinity, magnesium hydroxide (MH)/siloxane nanocomposite flame retardants were prepared by the hydrothermal and hypergravity method. The MH and MH/siloxane particles were characterized and analyzed by transmission electro…
High-quality epitaxial ZnO films on c-plane sapphire substrates have been obtained by utilizing an off-axis sputtering configuration together with buffer layers prepared via nitrogen-mediated crystallization (NMC). The role of NMC buffer layers is to provide high density of nucleation site and, thus, to reduce the str…
