“…The applicative potential of TiO 2 -photocatalysis is presently focused on the areas such as environmental remediation (water treatment [2][3][4] and air purification [5]), renewable energy processes-water splitting for hydrogen production [6], conversion of CO 2 to hydrocarbons [7], solar cells [8]-and self-cleaning surfaces [9]. TiO 2 is characterized by those properties that are indispensable to fulfill the requirements of efficient, stable, and green photocatalytic material (long term stability, chemical inertness, corrosion resistance, non-toxicity) [1].…”

Modification of titania with copper is a promising way to enhance the photocatalytic performance of TiO 2 . The enhancement means the significant retardation of charge carriers' recombination ratio and the introduction of visible light activity. This review focuses on two main ways of performance enhancement by copper species-i.e., originated from plasmonic properties of zero-valent copper (plasmonic photocatalysis) and heterojunctions between semiconductors (titania and copper oxides). The photocatalytic performance of copper-modified titania is discussed for oxidative reaction systems due to their importance for prospective applications in environmental purification. The review consists of the correlation between copper species and corresponding variants of photocatalytic mechanisms including novel systems of cascade heterojunctions. The problem of stability of copper species on titania, and the methods of its improvement are also discussed as important factors for future applications. As a new trend in the preparation of copper-modified titania photocatalyst, the role of particle morphology (faceted particles, core-shell structures) is also described. Finally, in the conclusion section, perspectives, challenges and recommendations for future research on copper-modified titania are formulated.

“…Recently, plasmonic effects have been applied in many applications including green energy harvesting such as thermal and solar energies as in [2]. For example, in [3][4][5], the application of thermos-plasmonic in membrane energy process was discussed. Nevertheless, such a technology led to design efficient Terahertz detectors with a thermoelectric response [6].…”

Abstract-Due to urgent needs for exploring new energy resources, a novel approach is developed in this paper to integrate the functions of a photovoltaic (PV) panel with an ultra-wide band (UWB) antenna array as a unit for collecting solar energy and RF radiation power. The UWB antenna is printed on the front panel of the PV surface. The antenna structure is customized with minimum shadowing effects on the PV surface, by using eight monopoles connected to one SMA port as a single antenna array. Then, to ensure the bandwidth enhancement, each monopole is coupled to three Split Ring Resonators (SRR) structured in a single column as a matching circuit. Next, an experimental study is performed to investigate the amount of the harvested energy from both the PV and the antenna array. The antenna experimental measurements are conducted to realize the I-V characteristics for the PV and produced output voltage and efficiency from the RF radiation power at 900 MHz only. Numerically, the proposed antenna array performance is simulated by CST MWS and HFSS software packages. Finally, the antenna performance in terms of S 11 and the radiation pattern at 900 MHz are measured and compared to the simulated results to end up with excellent agreements.

“…SPPs have been identified as promising building blocks for the next-generation integrated optical components [1], circuits [2] and membrane units [3,4]. So far, many various types of practical SPPs waveguides have been proposed with the advance of micro-fabrication techniques, among which metallic nanowires are typical one-dimension waveguide structures with relatively low losses at visible and near-infrared spectral range.…”

Abstract-Metal nanowires have drawn much attention due to the highly confined electromagnetic waves and relatively low propagation loss. With the increasing application potentials, we desire deeper insight into the mode behavior guided by metal nanowires for routing and controlling SPPs modes. Here, we apply the analytical solution for analyzing SPPs modes of metal nanowires. Single mode propagation condition and modes number are studied based on the analytical model. A universal formula of field diameters for all guided modes is presented, and mode field diameters are investigated. Finally, the intensity profiles of allowed guided modes are studied for specific dimensions.
