Zusammenfassung In dieser Studie wurden Makro- und Mikrokunststoffe in einem Größenbereich von 10–0,63 mm in neun Komposten aus drei, nach dem Stand der Technik betriebenen österreichischen Kompostanlagen untersucht. In den untersuchten Komposten wurden zwischen 13 und 111 Kunststoffpartikel pro kg TM gefunden. Eine H…
The dependency of the static residual tensile strength for the Glass Fiber-Reinforced Plastic (GFRP) laminates after impact on the impact energy level and indent shape is investigated. In this study, two different laminates, unidirectional, [0°2]s) and TRI (tri-axial, (±45°/0°)2]s), were prepared using the vacuum infu…
The conductive stretchable nanocomposite fibers, synthesized by the wet spinning technology, are typically composed of conductive nanofillers and polymer matrix to achieve both high electrical conductivity and stretchability. However, the inclusion of nanofillers blocks the solvent extraction passages, resulting in la…
Cu, Zn superoxide dismutase (SOD1) is a representative antioxidant enzyme that catalyzes dismutation of reactive oxygen species in cells. However, (E,E)-SOD1 mutants in which both copper and zinc ions were deleted exhibit pro-oxidant activity, contrary to their antioxidant nature, at physiological temperatures, follow…
In the article, the results of experimental researches of elements of structural steel reinforced slabs are presented. And the particularities of the work of structural designs under load are identified.
In the paper, the tests have been analysed for fire-resistant quality of the hollow-core reinforced-concrete floors with fire-retardant plaster covering under standard temperature regime of the fire. Using the methodology for determining the characteristics of fire-retardant coatings ability for reinforced-concrete fl…
The sustained release of an antiretroviral agent to women mucosa has been proved as an excellent strategy to reduce the sexual transmission of HIV. Hybrid micro-mesoporous particles have been synthesized and functionalized with a silane coupling agent followed by loading the antiretroviral tenofovir. It has been obser…
The novel copolymerization polyimide (PI) hollow fibers (HFs) of 4,4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) containing –CF 3 groups were prepared and investigated through both simulation and experiment. To demonstrate the alteration attributable to the introduction of fluoromonomers, the condensed sta…
Abstract Inverted packaging structure is a promising alternative for thermal isolation between light-emitting diode (LED) chips and quantum dot (QD) converters with effective heat dissipation. However, serious reflection loss occurs at the lead frame owing to the inverted bonding of LED chips. In this study, the scatt…
Microspheres are small particles of spherical form with form below 200 m. The analysis is concerned with the microspheres of its benefits, demerits, forms, planning, results and implementation of process variables. Here, in this article it is one of the novel drug delivery system.
Performing reactions in the presence of self-assembled hierarchical structures of amphiphilic macromolecules can accelerate reactions while using water as the bulk solvent due to the hydrophobic effect. We leveraged non-covalent interactions to self-assemble filled-polymer micelle nanoreactors (NR) incorporating gold…
Abstract A thermal-responsive Y-shaped amphiphilic block copolymer, namely poly(N-isopropylacrylamide-block-[poly(ε-caprolactone)]2 (PNIPAAm-b-PCL2), was synthesized through the combination of atom transfer radical polymerization (ATRP) and ring-opening polymerization (ROP) techniques, and its potential as smart anti-…
Despite the very high efficiency at blue wavelengths, nitride-based light-emitting diodes suffer from low efficiencies in the green and red spectral ranges. Different solutions have been proposed to mitigate the ``green gap,'' including the addition of an ($\mathrm{Al}$,$\mathrm{Ga}$)$\mathrm{N}$ capping layer to the…
Laboratory and process measurements from spectroscopic instruments are ubiquitous in pharma processes, and directly using the data can pose a number of challenges for kinetic model building. Moreover, scaling up from laboratory to industrial level requires predictive models with accurate parameter values. This means t…
Charge transport properties near the interface of organic material are one of the most fundamental research fronts of organic transistors. Although carrier mobility has been well studied in bulk single crystal organic semiconductors based on field effect transistors, the experimental result of mobility anisotropy is f…
MoS2/g-C3N4 (g-C3N4 [Formula: see text] graphitic carbon nitride) composite is considered as a promising photocatalyst for hydrogen production, while the preparation method still needs to be improved. Herein for the first time, nanosized MoS3 and melamine were used as starting materials and a facile one-pot calcinatio…
Understanding the surface properties of hybrid perovskite materials is a key aspect to improve not only the interface properties in photovoltaic cells but also the stability against moisture degradation. In this work, we study the local electronic properties of two series of CH 3 NH 3 PbI 3 perovskite films by atomic…
Random Al2O3 nanoparticle-based polymer composite films are investigated as external scattering layers to enhance light extraction from flexible organic light-emitting diodes (OLEDs). We found that the size and concentration of the nanoparticles (NPs) in the polymer film play a crucial role in improving light extracti…
In this article, an antenna with the combination of the microstrip slot and Yagi antenna is presented for wideband WLAN (wireless local area network) using CRLH (composite right/left-handed) as a metamaterial (Left-hand) element. The T-shape feed line is investigated as a radiator section and modified for enhancing th…
Abstract For the oxygen removal from coke oven gas (COG) the catalytic activity of commercial catalysts CoMo/γ‐Al2O3 and NiMo/γ‐Al2O3 was evaluated after a sulfidation pretreatment and compared to the Pt/γ‐Al2O3 reference catalyst. Elemental analysis and temperature‐programmed desorption showed that the oxidation reac…
