We report flexible ZnO thin film transistors (TFTs) fabricated on 5 μm thick solution-cast polyimide substrate. Plasma enhanced atomic layer deposition (PEALD) was used to deposit Al2O3dielectric and ZnO active layers respectively. The highest processing temperature was 200 °C. The flexible ZnO TFTs we fabricated have…
In this study, the dielectrophoretic processes of SiC nanowires suspended in three typical solvents, (highly purified water, ethanol and isopropanol) were systematically investigated. Optical microscope and SEM characterizations were used to observe the order of SiC nanowires on the surface of gold microchannels. The…
To improve its corrosion resistance from artificial saliva, 316L orthodontic brackets were subjected to surface modification by laser remelting.The experimental results showed that the passive films of 316L orthodontic bracket in artificial saliva have n-type semiconducting properties.The improvement of 316L orthodont…
First-principle calculation was performed to illustrate the atomic arrangement and segregation behavior of Sn/Ti and O in Σ3[11¯0](111) grain boundary, and the interaction of oxygen interstitials with Sn/Ti atoms on the grain boundary was studied. The analyses on the segregation energies and geometric positions, and t…
Abstract Supported Na2WO4/ZSM5 as catalyst was used for deep oxidative desulfurization (ODS) of mixed thiophenic compounds model oil and natural gas condensate under mild conditions by using hydrogen peroxide as oxidant. A one factor at a time optimization strategy was applied for optimizing the parameters such as tem…
Asymmetric polymerization of polydiacetylene (PDA) from commercially available achiral derivative of diacetylene monomer using circularly polarized pulse laser is demonstrated. Chiral source was only circularly polarized laser, and irradiation of left- and right-circularly polarized light effectively promoted the poly…
The paper deals with the technology and equipment for making a hardened antifriction surface layer of machine elements on the basis of using carbon nanomaterials in order to improve wear resistance. The paper presents the results of tribotechnical tests of pins according to standard techniques using an automated syste…
Pd and Pt modified N-doped titania nanoparticle powders were prepared by a facile sol-gel method. Nitrogen doping and metal modification were carried out simultaneously during the preparation pro- cess. The as-prepared samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), diffu…
The surface morphology, chemical composition, microstructure, nanohardness, and tribological properties of systems were investigated. The paper considers the methodology offilmpplicationusingionic-beam irradiation by means of the installation'Solo' with different exposure modes. Irradiation modes which allow an increa…
A numerical investigation of a stressed-strain state powder mixture with a melting component is carried out for the conditions of one-axial loading and nonstationary heating. The state of plane stress was assumed. The influence of the coupling between thermal and mechanical processes on temperature, stress and strains…
Eu-tris(dinaphthoylmethane)-bis-(trioctylphosphine oxide) (Eu-DT) molecules encapsulated by Polystyrene and bis(trimethoxysilyl)decane nanoparticles were prepared via a modified encapsulation-reprecipitation method and show a high sensitivity to sense temperature. After surface modification with poly-L-lysine, the flu…
In this study, we have been involved in the synthesis and characterization studies of a new cyclotriorganophosphazenes complex with protected phloroglusine ligand. Firstly,we synthesized hexachlorocyclotirphosphazene from ammonium chloride and phosphorus pentachloride reaction and then two hydroxyl groups of the phlor…
Abstract New ultra‐high strength steels provide new lightweight opportunities and improve crash properties in future car bodies. Understanding the joining process as well as the response of the base materials on heat input is in order to create designs exploiting the full potential and fulfill the extensive requiremen…
Micromaterials can be fabricated in a near infinite number of shapes, sizes, and chemical compositions. These micromaterials can subsequently be assembled into macro-sized constructs using bottom-up approaches as reviewed by A. Khademhosseini and co-workers on page 2130. Each type of micromaterial can provide a unique…
Abstract The gradient plasticity theory proposed by Aifantis and coworkers has been successfully used to model size effect phenomena at the microscale and nanoscale, by introducing into the formulation an internal length scale associated with the phenomenological coefficients of the gradient plasticity model. In this…
Magnetized target fusion is an alternative method to fulfill the goal of controlled fusion, which combines advantages of both magnetic confinement fusion and inertial confinement fusion since its parameter space lies between the two traditional ways. Field reversed configuration (FRC) is a good candidate of magnetized…
Novel self-doped n-type conducting polymer, poly(p-methylpyridinium vinylene), PMePyV were synthesized by using the quaternization of poly(p-pyridyl vinylene), PPyV and several regiochemical consequences in this polymer were proposed. The electrical, optical, and, electrochemical properties of self-doped n-type conduc…
On page 2085, Z. Bian and co-workers develop a type of structurally rigid organic ligand for constructing highly luminescent and highly photostable europium complexes. Unlike the traditional β-diketone complexes, these compounds possess robust chemical structure and can endure high energy UV irradiation, which may off…
Abstract In many illumination problems, the beam pattern needed and/or some geometrical constraints lead to very asymmetric design conditions. These asymmetries have been solved in the past by means of arrangements of rotationally symmetric or linear lamps aimed in different directions whose patterns overlap to provid…
Dynamic buckling of stiffened panels under axial compression loading having the form of finite duration pulse was analyzed by finite element modeling. Welding induced defects modifying the skin plate curvature were incorporated. Material degradation in the heat-affected zone was also taken into account. The Budiansky…
