The wetting control of graphene is of great interest for electronic, mechanical, architectural, and bionic applications. In this study, the wettability of graphene-laminated micropillar structures was manipulated by changing the height of graphene-laminated structures and employing the trichlorosilane (HDF-S)-based se…
Sr2Ti7O14, a new phase, is synthesized by leveraging the innate chemical and thermo-dynamic instabilities in the SrTiO3-TiO2 system and non-equilibrium growth techniques. The chemical composition, epitaxial relationships, and orientation play roles in the formation of this novel layered phase, which, in turn, possesse…
Abstract Due to limitation of computation resources and/or computation time many thermal problems require to use simplified geometrical models with equivalent thermal properties. A new method for definition of equivalent thermal conductivity of spent nuclear fuel storage casks is proposed. It is based on solving the i…
This work describes the preparation and validation of single-chain semiconducting polymer dots (sPdots), which were generated using a method based on surface immobilization, washing, and cleavage. The sPdots have an ultrasmall size of ∼3.0 nm as determined by atomic force microscopy, a size that is consistent with the…
In this work, we report a systematic study of CVD synthesizing graphene on different crystal faces of sapphire (c-Plane, m-Plane, and r-Plane). Nickel films are deposited on sapphire substrates with c-Plane, m-Plane, and r-Plane to catalyzing the growth of graphene by CVD (Chemical Vapor Deposition) method. It is only…
A method for studying fluctuations in the microscopic emission parameters of flat multiple-point cathodes has been developed. For field emitters based on polymer/multiwalled carbon nanotube nanocomposites, the statistical distribution of the effective heights of emission centers has been obtained. Numerical estimates…
Calcified coccolithophores generate calcium carbonate scales around their cell surface. In light of predicted climate change and the global carbon cycle, the biomineralization ability of coccoliths has received growing interest. However, the underlying biomineralization mechanism is not yet well understood; the lack o…
The influence of Bi doping on the charge carrier transport mechanism in GST225 thin films was investigated. The three regions with different current-voltage dependencies were established. The energy diagrams for Bi doped GST225 thin films for different regions were analyzed. Analysis of experimental data showed that s…
Separation of emulsified water from a low sulfur diesel fuel using coalescence filtration was studied in this work. Multilayer coalescence elements were manufactured in-house using the meltblow technique with or without an electric field applied directly to jets of molten polypropylene. The results were compared with…
Crystallization elution fractionation (CEF) is a relatively new polyolefin characterization technique used to estimate the chemical composition distribution (CCD) of semicrystalline copolymers. CEF is developed to enhance the resolution and reduce the analysis time of temperature rising elution fractionation (TREF) by…
Magnetoelectric (ME) coupling for PZT/Ni composites with PZT embedded in Ni is investigated under combined magnetic and compressive loadings. As the applied compressive stress increases, the ME coefficient (?ME) rises monotonically. Incorporating the size effect of the composites, we present a linear relationship betw…
Hepatocellular carcinoma (HCC) is one of the most common malignant human tumors worldwide, but no effective therapeutic options are currently available. The cancer stem cell (CSC) has proven to play a central role in the development, metastasis, and recurrence of HCC. In this study, we report a dual functional mitogen…
A ring-shaped pattern was observed in the field emission from ZnO nanowires. These ring patterns are different from those previously reported from metallic or carbon nanotube emitters, which occur under high current density. The influences of the applied field and anode to emitter distance on the ring-shaped pattern h…
This paper discusses the effect of different surface treatments on shape memory alloy wires embedded in PolyEster (PE) and VinylEster (VE) polymeric matrices. In particular, two types of chemical etching and a chemical bonding with a silane coupling agent have been performed on the surfaces of the wires. Pull-out test…
In order to investigate behavior of magnetic field-induced reverse martensitic transformation for Ni-Co-Mn-Sb, magnetization experiments up to a static magnetic field of 18 T and a pulsed magnetic field of 40 T were carried out. In the thermomagnetization curves for Ni41Co9Mn39Sb11 alloy, the equilibrium transformatio…
Surface recombination on ZnO nanowires (NWs) dominates over photogenerated carrier collection unless band bending and electrochemical reactions facilitate charge separation. We studied acetonitrile electrolyte with tetrabutylammonium perchlorate, with and without redox mediators (ferrocene/ferrocenium, iodide/triiodid…
Thin film processes of organic radicals remain widely unknown, although these materials may have a significant technological potential. In aiming at their use in applications, we explore the electronic structure of thin films of a nitronyl nitroxide radical attached to a fluorophore core. According to our findings, th…
Graphene/PANI nanofibers composites are prepared for the first time using a novel in situ polymerization method based on the chemical oxidative polymerization of aniline using heparin as a soft template. The even dispersion of individual graphene sheet within the polymer nanofibers matrix enhances the kinetics for bot…
The quest for sustainable materials as a consequence of a global drive to mitigate climate change has led to a focus on natural fiber–reinforced composite materials. In this study, skillful ply angle arrangement of bark cloth–reinforced laminar epoxy composites was carried out for the first time using vacuum-assisted…
To investigate the influence of deposition pressure on the texture of pyrolytic graphite, a series of experiments were carried out. The pyrolytic graphites were fabricated at 2000°C with propylene as the carbon source and nitrogen as the carrier gas in a system pressure from 1·1 to 1·8 kPa. Results show that lowering…
