Cork is a renewable and biodegradable raw material, which was directly stripped from the periderm of oak bark. The natural amphiphilic chemical composition endowed its pristine surface with hydrophobicity and superoleophilicity in air. Based on the wettability of pristine cork, a stable superhydrophilic and superoleop…
Abstract Polymeric insulating materials like an epoxy resin due to their excellent electric performance and a maintenance performance are commonly applied to various power equipment. Additives and fillers are traditionally added into the epoxy resin to improve the mechanical and thermal properties. The epoxy/hollow pa…
A time-domain perturbation method (TDPM) for simulating nonlinear metallic metasurface elements with Maxwell-hydrodynamic model is presented. Finite-difference time-domain (FDTD) method is implemented to the model with peculiar boundary conditions on metallic surfaces. A complete numerical algorithm is developed accor…
Herein the microstructure evolution and microhardness variations in a peak‐aged Al–Zn–Mg alloy after equal‐channel angular pressing (ECAP) for 1–8 passes followed by heat treatments at temperatures of 393–473 K for 5–20 h are examined. The results show that ECAP processing hardens the alloy, and the hardness increases…
Nanoparticles have great impact due to their tremendous industrial applications. However, their applications have produced toxicity effects on the aquatic environments and their detailed analyses are not clearly understood. Iron oxide nanoparticles (Fe2O3 NPs) are being used extensively in many industries but are cons…
The development of facile strategies for simultaneously tailoring robust pore hierarchy and integrated microstructures in carbonaceous materials is critical for the efficient multiscale control of fluid, molecular/ionic, and charge transport in applications spanning separations, catalysis, and energy storage. Here, we…
As automotive lamps are highly integrated, the heat generated from bulbs reduces the light quantity and lifespan of the bulbs. Numerous studies have been actively conducted worldwide on heat dissipation designs and material modifications for heat release. In this study, an analysis was carried out of the mechanical, t…
In the present work, using Heusler Ni49+xMn36-xIn15 (with x = 0 and 0.5) alloys, it is shown that the choice of the appropriate measurement protocol (erasing the prior state of the sample in between experiments) in ∆Tad first shot characterization is crucial for obtaining reliable results. Unlike indirect measurements…
Recently, rare-earth-doped infrared (IR) luminescent glasses have drawn massive attention due to their potential applications in military, medical, and communications fields. In this Letter, we present a system of oxychloride Si-Ge-O-Cl glasses, suitable for rare-earth doping, which has been developed as a new, to the…
Magnesium oxide (MgO) powders are prepared by liquid-phase method and are characterized by X-ray diffraction (XRD), SEM and EDX characterization studies. The characterization confirms that MgO particles obtained shows cubic structure. The synthesized powders have high purity. The XRD analysis shows that nanocrystallin…
Raman Spectroscopy of ZnO Nanowires Obtained by Electrochemical Anodization: Effect of Thermal Treatment, Voltage and Anodizing Time, Zamora Peredo, Luis, Ceballos Valle, Alan, Baez, Adriana, Hernádez-Torres, Julián, García-González, Leandro, Orozco-Cruz, Ricardo
Pure and Nickel (Ni) doped zinc oxide (ZnO) thin films with different concentrations (1%, 3% and 5%) were fabricated using one of the simplest physical deposition processes called Successive Ionic Layer Adsorption and Reaction (SILAR) method. The physico-chemical properties of the fabricated ZnO and Ni-doped ZnO thin…
The mechanical bonding of dissimilar metals though the application of high‐pressure torsion (HPT) processing is developed recently for introducing unique ultrafine‐grained alloy systems involving microstructural heterogeneity leading to excellent mechanical properties. Considering further developments of the processin…
Abstract Multiple source partial discharge (PD) separation is indispensable in on-line PD measurements, particularly for large generators. For this purpose, an improved density peak clustering algorithm for the separation of a multi-source PD is presented. DPC is characterized by the selection of cluster centers from…
A composite iodine sorbent was obtained in the form of porous polymer matrix with activated carbon particles impregnated with triethylenediamine deposited on its surface. A comparative assessment of the radioactive methyliodide capturing efficiency by the composite sorbent and a sample of industrial charcoal sorbent w…
The increasing energy crisis promotes the study on novel electrode materials with high performance for supercapacitive storage and energy conversion. Transition metal phosphates have been reported as a potential candidate due to the unique coordination and corresponding electronic structure. Herein, we adopted a facil…
Topological constraint theory (TCT) has revealed itself to be a powerful tool in interpreting the behaviors of amorphous solids. The theory predicts a transition between a ‘rigid’ overconstrained network and a ‘floppy’ underconstrained network as a function of connectivity or average coordination number, . The predict…

Abstract A reduced model of high-Z impurities erosion and redeposition is presented to analyze net erosion of tungsten material in divertor attached plasma conditions measured in DIII-D experiments. This reduced model is tailored to quantify the redeposition and the net erosion on high-Z material samples of sufficient…
