Self-powered sensing systems that can work without external power sources have recently been demonstrated to detect pH, humidity, pressure, and temperature. By harvesting energy directly from the environment, these self-powered sensing systems are advantageous in minimizing the size, having long-term operation, and av…
Double perovskites RBaB2O6-δ and Sr2BMoO6, where R=rare-earth element and B=3d-transition metal, with A-site and B-site, respectively, cation ordering are very promising materials for a variety of different devices for moderate high temperature applications such as solid oxide fuel cells (SOFCs) and mixed ionic and el…
AlGaN alloys are the building blocks for deep UV optoelectronics and high-power devices. It has been demonstrated that the highest crystalline quality AlGaN films with high Al content are obtained on AlN single crystal substrates. The resulting mismatch between AlGaN and AlN causes a compressive strain within the AlGa…
The threshold gain of a quasi-static spaser depends only on the dielectric functions of the metal and gain material, while the nanoparticle shape or spasing mode define the resonant wavelength. The figure illustrates this on the example of silver shells embedded in gain material, and shows how the threshold gain incre…

Oxygen electrodes in solid oxide electrochemical cells such as Solid Oxide Fuel Cells (SOFCs) or electrolysers (SOECs) are typically based on LaBO3 perovskites, where B is a transition metal such as Co, Mn or Fe. In order to impart oxide ion conductivity and electro-catalytic activity towards oxygen exchange, the La i…

This work presents the fabrication and characterization of multi-layered three-dimensional (3D) pyrolysed carbon microelectrodes for electrochemical applications. For this purpose, an optimized UV photolithography and pyrolysis process with the negative tone photoresist SU-8 has been developed. The fabricated three el…
Significance and Use 3.1 The sound transmission loss provided by a material that covers a flat surface depends not only on the physical properties of the material but also on the type of structure to which it is mounted and the mounting method used. 3.2
The commercialization of PEFCs depends significantly on reduction of the costly precious metal content in fuel-cell electrodes. To achieve this goal, a high-performance low-loaded electrode must be utilized; and there is a need to understand the key transport resistances and processes within such a structure. The cata…
Global functional additive manufacturer Total Cray Valley (TCV), headquartered in Exton, PA, USA, has introduced a new processing aid for rigid polyvinyl chloride (PVC). Cleartack W-110 is a non-acrylic product that reportedly offers improved thermal stability and performance properties.
The cover picture shows Zn0@ZnS core-shell nanoparticles and their synthesis via intermediate Zn0 nanoparticles. Zn0 nanoparticles (8 nm in diameter) are prepared by sodium naphthalenide ([NaNaph]) reduction of ZnCl2 in tetrahydrofuran. The intermediate, highly reactive Zn0 nanoparticles are partially oxidized thereaf…
Spectral broadening of blue apatite phosphors (Sr, Ba)5(PO4)3Cl:Ce3+ was achieved by changing Sr-Ba cation combinations. Their blue emission colors come from the 5d1-4f1 transition of Ce3+ ions, and their excitation bands are ranged from 250 nm to 400 nm. The substitution of Ba2+ for Sr2+ ions was confirmed by Raman s…
The materials used in the present investigation were filled silicone rubbers supplied by Shin-Etsu Chemical Co., Ltd. in Japan. Two kinds of silicone rubbers were studied in the hardness levels of Shore A 50 and 80.
