In article 1603544, S.-W. Kim and co-workers introduce graphene tribotronics for touch-sensing applications. The working mechanism is based on a coplanar coupling of triboelectrification and current transport in graphene field-effect transistors. The touch sensors are ultra-sensitive, fast and can spatially map the mo…
We study grain boundaries between striped phases in the prototypical Swift--Hohenberg equation. We propose an analytical and numerical far-field-core decomposition that allows us to study existence and bifurcations of grain boundaries analytically and numerically using continuation techniques. This decomposition overc…
Abstract. Stabilizing colloidal suspensions helps prevent scale deposition and inorganic particulate matter fouling in aqueous systems. Colloidal suspension stabilization was modeled using iron oxide (Fe2O3) suspensions in synthetic tap water containing a mixed electrolyte system that included a variety of ions intera…
Superaustenitic stainless steel UHB 904L with high Mo concentrations is widely used in applications that require high toughness and corrosion resistance.Given certain thermal histories, UHB 904L may be susceptible to the formation of potentially detrimental intermetallic phases, such as the 𝜎 (sigma) phase.The formati…
In order to improve interfacial adhesion between the thermoplastic matrix and the carbon nanofibers (CNFs), two-step oxidization by using mixed acid and hydrogen peroxide was performed on the CNFs. Moreover, polyamide 11 (PA11) based composites reinforced with the oxidized CNFs were fabricated, and tensile properties…
Grape anthocyanin efficiency as a corrosion inhibitor for 2024-T3 aluminum alloy was evaluated by electrochemical techniques such as, electrochemical impedance spectroscopy and cathodic and anodic potentiodynamic polarization.The inhibitor behavior for 2024-T3 aluminum alloy was investigated in 800, 1000, 2000, 3000,…
In this study, a water electrolyser was designed and manufactured to produce hydrogen and oxygen mixture (H2/O2). The produced gas was consumed instantaneously in order to eliminate the need for a storage device. The objective of the study was to investigate the effect of adding this mixture at various flow rates (0 L…
In this study, we investigated how the yarn used in single tricot stitch affects the hand evaluation of knitted tapes for fasteners. For this purpose, experimental tapes that differed only in the yarn of the single tricot stitch were evaluated using the paired comparison method and their mechanical properties were mea…
In the current work, a series hybrid vehicle has been constructed that utilises a dual-fuel, reactivity controlled compression ignition (RCCI) engine. Full vehicle testing was conducted on chassis dynamometers over the US Environmental Protection Agency Federal Test Procedure, Highway Fuel Economy Test and US06 using…
In the steel refining process, a metal emulsion in which metal droplets are dispersed in the slag phase plays an important role in improving the reaction efficiency. In a previous study, the formation of metal emulsions was experimentally evaluated using Pb or Al alloys as the metal phase and chloride salt as the slag…
Hemp is a non-psychoactive variety of cannabis sativa L. The crop is one of historical importance in the U.S. and reemerging in worldwide importance as manufacturers seek hemp as a renewable and sustainable resource for a wide variety of consumer and industrial products. The fiber has high tensile strength and can be…
Two-dimensional (2D) materials have a unique crystal structure and excellent properties, which renders it possible to be used to construct novel artificial nanostructures and design novel nanodevices, thereby achieving a breakthrough in the semiconductor field. In this review paper, the basic behaviors of the ambipola…
Fiber reinforced polymer composites with their outstanding performance are increasingly used in aerospace products. Currently aeronautical composites are mainly fabricated using autoclave curing technologies, but the long cure cycle, high energy consumption and large temperature gradients in composite thickness seriou…
In this work, the influence of process and material parameters on the draw resonance instability in film casting and fiber spinning is investigated both theoretically and experimentally. Draw resonance generally occurs if the draw ratio, i.e., the ratio of outlet to inlet velocity, exceeds a critical value, and manife…
Graphene, a two-dimensional sheet of sp2-hybridized carbon material, possesses excellent properties, such as high carrier mobility, high electrical conductivity, high thermal conductivity, strong mechanical strength and quantum anomalous Hall effect. So graphene quickly lights the enthusiasm for its research and appli…
The NbC precipitated in steel is in favor of the heterogeneous nucleation of ferrite, which is affected by the alloying elements at the ferrite/NbC interface. However, it is difficult to clearly understand the effect of alloying elements on the ferrite/NbC interface behavior experimentally. Therefore, the first-princi…
Semiconductor photocatalysts have received much attention due to their applications of wastewater treatment and air purification. The monoclinic -AgVO3, which has narrow band gap (2.11 eV) and can respond to visible light, has been considered as one of the promising semiconductor photocatalysts. The vacancy defects al…
The real and imaginary parts of the eigen complex wave vector in a stratified lossy chiral medium for the case of oblique incidence are derived by using the phase-matching condition. Due to the fact that the real and imaginary parts are nonparallel, the eigen wave propagating in the medium is inhomogeneous. Then the r…
Water is a notoriously difficult substance to model both accurately and efficiently. Here, we focus on descriptions with a single coarse-grained particle per molecule using the so-called approximate non-conformal and generalized Stockmayer potentials as the starting points. They are fitted using the radial distributio…
Eutectic phase transition involves the competitive nucleation and coupled growth of two solid phases within one liquid phase. Phase selection especially under unequilibrium condition, may result in novel microstructures and thus affects the performances of eutectic alloys. Liquid Cu-10 wt.% Zr hypoeutectic, Cu-12.27 w…
