High Resolution Image Download MS PowerPoint Slide A robust and reliable method for enhancing the photoluminescence (PL) of multilayer MoS 2 is demonstrated using an oxygen plasma treatment process followed by laser exposure. Here, the plasma and laser treatments result in an indirect-to-direct band gap transition. Th…
Thin metal-oxy-nitride layers are widely used for wavelength selective optical coatings. We aimed to prepare composition spread metal-oxy-nitride combinatorial layers by reactive radiofrequency sputtering for a highly efficient characterization of their optical properties in a wide range of O/N ratios. Affinity of met…
Lime soap dispersants function in a physical manner, to be discussed in Sec. III, without covalent or ionic bounding. By contrast, a chelating agent or an ion-exchange agent forms chemical bonds with calcium, magnesium, or other polyvalent ions. The Borghetty-Bergman test was used in the systematic study because it is…
The aim of this study is to extend our general approach to the spatial resolution in the quantitative element analysis that can be achieved with a FEG-EPMA by systematic measurements of the depth resolution. The test specimens are Al and Ag surface layers with various thicknesses on top of non-fluorescent substrates.…
Abstract A floating metal layer (FML) is realized over vertically aligned nanorod arrays (NRAs) using a newly developed angle deposition technique (ADT) that utilizes simultaneous metallization from two identical metal sources. The angle of the sources formed with the tip of the nanorod creates a shadow onto adjacent…
This paper provides the background for a new method in fatigue life calculations for polyvinyl chloride (PVC) pipe developed by Utah State University that is simple to use and is the recommended practice by the PVC pipe association. Design engineers must select an appropriate pipe wall thickness (or DR) that will acco…
Abstract Deactivation is the major challenge of heteroatom‐substituted mesoporous silica materials for large scale applications. Here we report the impact of plugging of mesochannels of AlSBA‐15 on activity and stability of liquid‐phase acylation of anisole with (extremely) low catalyst loadings of 0.15–0.6 wt.% and 0…
We report a novel high-pressure cubic cF24 phase of TaSi2 which is stable above 185 GPa through first-principles swarm intelligence structure search method. Results on enthalpy difference show that the structural transition of TaSi2 from the ambient hexagonal C40 phase to cF24 phase is first order with a volume drop o…
Abstract “Non-Fickian” diffusion of wood moisture refers to the unexplained anomalous behaviour of water vapour sorption in wood. The depression of moisture diffusion rates in thin sections of wood tissue during moisture content change at high relative humidity is one of the least-understood aspects of “non-Fickian” d…
Since the terrorist attacks on 11 September 2001, structural resistance to explosion has received increasing attention. As bridges are controlling factors in traffic systems, explosion-induced bridge damage will cause great economic loss and social impact, but there is a lack of anti-explosion research for bridges. Th…
A magnetostrictive ferromagnet–polymer composite consisting of steel wires suspended in a polymer matrix has been developed that exhibits large reversible magnetostrictive strain in relatively low magnetic fields. The strain for a fixed field is a nonmonotonic function of wire loading for the longer wires investigated…
We study the near-infrared properties of spherical multishell nanoparticles comprising a loss-less dielectric core enclosed by a concentric layering of metallic–dielectric–metallic nanoshells. The coupling between the metallic shells induces plasmon resonance redshifts and peak splitting in the absorption spectra of t…
Abstract The phase transition between λ-Ti 3 O 5 and β-Ti 3 O 5 is an intriguing process that can be driven in multiple ways. However, the phase transition has not been reasonably and universally analyzed in atomic-scale, because it is limited by experimental inaccessibility. Here, the nudged elastic band method, crys…
Nowadays, with the spread of terrorist attacks in many parts of the world, the design approach to abnormal loadings, such as a blast load, has also become noted of design regulations. In recent years, the dual moment-resisting frame system with steel plate shear wall has been used in the design of structures as a load…
Abstract Laser initiation of energetic materials is a topic of significant interest. An extremely important parameter of initiation for numerous applied tasks is the time delay of initiation from the beginning of laser exposure. Experimental studies of the process of initiation of a number of primary explosives (lead…
Natural attenuation of explosives may occur through microbial mineralization, microbial transformation, and/or immobilization. A demonstration of natural attenuation of explosives was conducted at a former waste lagoon area, at the Louisiana Army Ammunition Plant (LAAP). Objectives of the demonstration were to establi…
To obtain the good flatness of hot-rolled stainless-steel strips, high-precision shape control has always been the focus of research. In hot rolling, the quadratic wave (centre buckle and edge wave) can usually be controlled effectively. However, the quarter buckle of the strip is still a challenge to solve. In this p…
Fusion reactors will require specially engineered structural materials that will simultaneously satisfy the harsh conditions, such as high thermomechanical stresses, high heat loads, and severe radiation damage, without compromising on safety considerations. The simulation of 14.7-MeV protons and 3.6-MeV α-particles i…
We report on the effect of low substrate temperature on the correlation between structure, magnetic properties, and micromagnetic behavior of Fe70Ga30thin films. The enhanced grain size and the decrease in the number of pinning centers are in correlation with the enhanced saturation magnetization and domain size (~0.2…
A ternary solid solution of lead-free Na1/2Bi1/2TiO3-BaTiO3and BiGaO3 (NBT-BT-BG) was prepared using conventional, solid-state synthesis. Compositions were prepared near the morphotropic phase boundary (MPB) of (1- x)NBT-x BT, located near x= 0.04 -0.09, and then systematically substituted with 2-5 mol% BG to investig…
