Abstract To avoid the complex core surface functionalization or pretreatment that is necessary in order to coat latex and silica colloids with a uniform, complete metal shell, solvent‐assisted route has been explored prepare (Ag Au) shell controlled thickness on polystyrene (PS) electroless plating approach, based electrostatic attraction, silver colloids. Without any additional treatment, as‐prepared core–shell can be crystallized directly into long‐range‐ordered structures photonic...

This letter proposes a novel Pareto optimal prediction interval construction approach for electricity price combing extreme learning machine and non-dominated sorting genetic algorithm II (NSGA-II). The intervals are produced with respect to the formulated two objectives reliability sharpness. effectiveness of proposed has been verified through numerical studies on Australia market data.

An easy, cheap, high‐throughput way to generate metallic wire arrays by patterned electrodeposition is reported. Copper electrodeposited on the surface of a regularly striped Langmuir–Blodgett film, forming an array submicrometer‐wide wires with homogeneous width (see Figure). Width and separation can be tuned template.

Over the years, probabilistic nature of renewable energy sources (RES) and its influence on power system adequacy have been well studied. However, rather less attention has paid to impact RES unit itself's conversion system's (PCS') reliability, as their various connection topologies. This paper devises a comprehensive sensitivity study how each these elements can affect overall generating reliability. given plethora configurations components, it is import identify most vulnerable element in...

Bi-based layered ferroelectric thin films of Sr2Bi4Ti5O18 (SBTi) were prepared by pulsed-laser deposition. The c-axis-oriented SBTi grown on SrRuO3 seeded Pt/TiO2/SiO2/Si substrates while polycrystalline substrates. measurements ferroelectricity revealed that the direction spontaneous polarization was not along c axis since much less than randomly oriented films. There no significant degradation switchable charge at least up to 1011 cycles for films, suggesting that, even with Ti which...

Ordered interconnected gold nanoshells and nanotubes (see figure) are made by electroless plating in a macroporous polymer replicated from non-close-packed silica colloidal crystal. The size of the can be altered varying sintering etching conditions for template. A remarkable modulation optical reflectivity resulting surface plasmon excitation has been observed microstructure.

Extreme events can extensively damage power systems, causing customers to experience long-lasting outages. During such events, an electric vehicle (EV) be used directly a house, i.e., vehicle-to-home (V2H). Specifically, the EV serves as mobile energy storage system-running errands "transport" from other places. Vehicle-to-grid (V2G) further allows cooperation among houses. It enables fleets take turns running so that sustained supply is possible. Moreover, autonomous driving technology also...

Highly conductive perovskite La0.5Sr0.5CoO3 thin films were grown on (012) LaAlO3 by pulsed-laser deposition at different substrate temperatures. Magnetoresistance (MR) measurements show only a negative effect for the temperature of 800 °C. However, positive MR was found lower temperatures 400 and 500 The sign magnetoresistance changed from to near 150 K under an applied magnetic field 5.0 T, largest 2.6% obtained 4.2 film Low-temperature hysteresis also studied, it is suggested that...

Optical harmonic generation in a three-component Fibonacci optical superlattice (3CFOS) is studied experimentally. Quasi-phase-matched second-harmonic spectrum and third-harmonic have been measured LiTaO3 3CFOS. Results show that the structure of 3CFOS richer than two-component superlattice. The intrinsic self-similarity shown its Fourier spectrum.
