In this paper, for the first time, the geometrical interpretation of fractional strain tensor components is presented. In this sense, previous considerations by this author are shown in a new light. The fractional material and spatial line elements concept play a crucial role in the interpretation.
Chirality plays a major role in recognition and interaction of biologically important molecules. The enzyme 3-deoxy-d-arabino-heptulosonate 7-phosphate synthase (DAH7PS) is the first enzyme of the shikimate pathway, which is responsible for the synthesis of aromatic amino acids in bacteria and plants, and a potential…
Abstract Die Oberflächensynthese von organischen Nanoschichten mithilfe reaktiver Metalloberflächen führt zu stark adsorbierten organischen Nanostrukturen, deren intrinsische Eigenschaften jedoch durch die starke Bindung zur Oberfläche verdeckt werden. Daher ist die Reduzierung der elektronischen Kopplung zwischen den…
The concept of an LED-based source with high lumen density is described. It contains a luminescent rod in which LED light is converted to light with a longer wavelength that is extracted from a small face of the rod. The fundamental limitations and possibilities are discussed, as well as the constituents needed. Resul…
Abstract The Accelerating Rate Calorimeter (ARC) is unique for its versatility of operation and application - reliability, validity, and accuracy of results - due to very high adiabaticity. Accelerating Rate Calorimetry is one of the screening tests employed to determine the suitability of a reservoir for air- injecti…
under different input energy was also measured to illustrate this result.
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…
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…
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(…
Energy-dispersive X-ray spectroscopy (EDX) performed using scanning transmission electron microscopy (STEM) in combination with a windowless detector setup allows high-resolution imaging and chemical composition mapping even of light elements present in low concentrations. The used TEM-system combines a field emission…
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),…
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…
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…
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…
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…
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…
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…
With ε-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20) and glycidyl azide polymer (GAP) as the solid filler and binder, respectively, GAP/CL-20-based compound explosives were designed and prepared. Using micro injection charge technology, the compound explosives were packed into small grooves to exp…
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…
Abstract A family of bamboo‐like metal–organic nanotubes consisting of in situ synthesized macromolecular blocks (MB) is reported. The MBs are composed of six fac ‐(CO) 3 Re cores, one benzene‐1,2,3,4,5,6‐hexaolate plate, and six pyridine‐derivative pillar ligands, which have a doubly tri‐legged geometry and can be mu…
