Gain enhancement of wideband circularly polarized antenna using FSS
This paper presents a high gain, wideband circularly polarized (CP) antenna. High gain of the antenna is achieved by employing a frequency selective surface (FSS) as a reflector. The antenna is a coplanar waveguide-fed structure with a modified L-shaped radiating patch. The unit element of the FSS is formed by connect…
The Influence of Contact Space on Arc Commutation Process in Air Circuit Breaker
In this paper, a 3D magneto-hydrodynamic (MHD) arc simulation model is applied to analyze the arc motion during current interruption in a certain air circuit breaker (ACB). The distributions of pressure, temperature, gas flow and current density of the arc plasma in the arc region are calculated, and the factors influ…
Temperature- and Pressure-Induced Structural Changes of Cobalt(II) in a Phosphonium-Based Ionic Liquid
Abstract The temperature- and pressure-induced paramagnetic switching of cobalt(II) complex in a binary mixture of phosphonium-based ionic liquid [P6,6,6,14]SCN and [Co(NCS)2] is reported. This arises from a structural change in the coordination of the cobalt(II) center from tetrahedral [Co(NCS)4]2? to octahedral [Co(…

ABSTRACT Four new 2,1,3‐benzooxadiazole‐based donor–acceptor conjugated polymers, namely poly{9‐(9‐heptadecanyl)‐9H‐carbazole‐alt‐5,6‐bis(octyloxy)‐4,7‐di(selenophen‐2‐yl)benzo[c][1,2,5]oxadiazole)}(PSBSC), poly{9‐(9‐heptadecanyl)‐9H‐carbazole‐alt‐5,6‐bis(octyloxy)‐4,7‐di(furan‐2‐yl)benzo[c][1,2,5]oxadiazole)}(PFBFC),…
Preparation of Composite Electrospun Membranes Containing Strontium‐Substituted Bioactive Glasses for Bone Tissue Regeneration
Barrier membranes used for the treatment of bone tissue defects caused by periodontitis lack the ability to promote new bone tissue regeneration. However, the addition of an osteogenic component to membranes may enhance their regenerative potential. Here the manufacturing of composite membranes made of poly(caprolacto…
Corrosion resistance of Al-based coatings in flowing Pb–15.7Li produced by aluminum electrodeposition from ionic liquids
Reduced activation ferritic–martensitic steels are intended to serve as structural materials in different blanket designs, e.g. HCLL, DCLL and WCLL. In these designs the material is supposed to be in direct contact with the flowing liquid breeder material Pb–15.7Li at an operating temperature of up to 550 °C. These co…
Photooxygenation of alkanes by dioxygen with p-benzoquinone derivatives with high quantum yields
Alkanes were oxygenated by dioxygen with p-benzoquinone derivatives such as p-xyloquinone in alkanes which are used as solvents to yield the corresponding alkyl hydroperoxides, alcohols and ketones under visible light irradiation with high quantum yields (Φ = 1000, 1600%). The photooxygenation is started by hydrogen a…
Adsorptive removal of PPCPs by biomorphic HAP templated from cotton
Biomorphic nano-hydroxyapatite (HAP) was fabricated by a co-precipitation method using cotton as bio-templates and employed in adsorptive removal of ofloxacin (OFL) and triclosan (TCS) that are two representative pharmaceuticals and personal care products (PPCPs). The surface area and porosity, crystal phase, function…
Development of a Design Methodology Against Fast Cook‐Off Threat for Insensitive Munitions
Abstract This work provides a design methodology for a typical energetic system to get Type V insensitive munition (IM) response against fast cook‐off threat. Experimental and numerical results for a generic test item filled with PBXN‐109 explosive are presented. Two key aspects of IM design against fast cook‐off thre…
High‐mobility flexible thin‐film transistors with a low‐temperature zirconium‐doped indium oxide channel layer
Thin film transistors (TFTs) with zirconium‐doped indium oxide (ZrInO) channel layer were successfully fabricated on a flexible PEN substrate with process temperature of only 150 °C. The flexible ZrInO TFT exhibited excellent electrical performance with a saturation mobility of as high as 22.6 cm2 V–1 s–1, a sub‐thres…

Bipolar Resistive Switching Behavior in Sol-Gel MgTiNiOxMemory Device
High-resistance state (HRS) current has significant effect on the reliability and power consumption of resistive switching memories. Low HRS current is helpful for obtaining ultra-low power and for high ON/OFF ratio nonvolatile memory application. The reduced HRS current of a sol-gel magnesium titanate nickelate-based…
