Retention of mechanical properties of phosphate glass fibre reinforced degradable polyesters such as polycaprolactone and polylactic acid in aqueous media has been shown to be strongly influenced by the integrity of the fibre/polymer interface. A previous study utilising 'single fibre' fragmentation tests found that c…
CONTEXT: Pharmaceutical solid dispersions are known to be seriously affected by issues of aging and processing. OBJECTIVE: This study investigated the spectral patterns in the solid dispersions (SD) of Nifedipine/Soluplus/Kollidon SR and the feasibility of the methodology in identification and evaluation of the solid…
Aluminium matrix composites (AMCs) having more than one reinforcement (hybrid AMCs) found enlarged use due to better strength, high thermal stability and wear resistance properties and can be a substitute for single reinforced AMCs .The effect of varying ball milled (BM) B4C/Si3N4 particles on the microstructure of as…
In recent years, stringent requirements of material quality in automotive and aerospace industries have necessitated the development of lightweight aluminum alloys. In this context, it is known that the metal–matrix composites offer a spectrum of advantages that are important for their selection and use as structural…
Fullerenol (C60(OH)24) nanoparticles (FNP) have a significant role in biomedical research due to their numerous biological activities, some of which are cytoprotective and antioxidative properties. The aim of this study was to measure distribution of fullerenol nanoparticles and zeta potential in cell medium RPMI 1640…
A grounded structure can interact with a lightning flash in two different ways. It can interact either with a downward or upward lightning flash. The initiation of a downward lightning flash takes place in the cloud, whereas in the case of upward lightning flash, the point of initiation is usually at the tip of a tall…
Al-graphite and Al-Nanographite particulate metal matrix composites were prepared by two step stir casting method. The reinforced particulates in the metal matrix composites varied from 5% to 10% by volume fraction. Tribological performances of these composites were evaluated based on graphite particle size and normal…
Protein phase behavior characterization is a multivariate problem due to the high amount of influencing parameters and the diversity of the proteins. Single influences on the protein are not understood and fundamental knowledge remains to be obtained. For this purpose, a systematic screening method was developed to ch…
With the present contribution, we demonstrate that the baseline separation of ketoprofen enantiomers can be successfully achieved (α = 1.09; R(S) = 1.60) in the reversed-phase mode of elution with a commercially available anion-exchange-based chiral stationary phase, incorporating the quinine 2,6-diisopropylphenyl car…
Abstract BACKGROUND Nutrient removal via nitrite was investigated in a sequencing batch reactor ( SBR ) treating reject water produced from the anaerobic digestion of sewage sludge and the subsequent dewatering process. The polyhydroxyalkanoate ( PHA ) storage capacity of the biomass obtained under nitrifying (nitrita…
TiO2 coatings deposited using reactive magnetron sputtering and spray coating methods, as well as Ag- and Mo-doped TiO2 coatings were investigated as self-cleaning surfaces for beverage processing. The mechanical resistance and retention of the photocatalytic properties of the coatings were investigated over a three-m…
Our understanding of upper atmospheric discharges has advanced significantly since the early 1990s, and a large amount of dedicated observational, experimental, theoretical, and modeling efforts have been made to study various aspects of TLEs. Many papers, including a few recent extensive review papers, have been publ…
Abstract MRI offers high spatial resolution with excellent tissue penetration but it has limited sensitivity and the commonly administered contrast agents lack specificity. In this study, two sets of iron oxide nanoparticles (IONPs) were synthesized that were designed to selectively undergo copper‐free click conjugati…
In the last decade direct detection Dark Matter (DM) experiments have increased enormously their sensitivity and ton-scale setups have been proposed, especially using germanium and xenon targets with double readout and background discrimination capabilities. In light of this situation, we study the prospects for deter…
The electronic properties of nanometer size Au(111) vacancy islands are modified by covering the islands with an atomically thin NaCl(001) layer. The large-scale commensurability between the atomic lattices of the cover layer and the islands gives rise to various Moiré-effect-induced standing wave patterns of which th…
We investigated the Ru spacer-thickness effect on the anti-ferro-magnetic coupling strength (Jex) of a [Co/Pd]n-synthetic-anti-ferro-magnetic layer fabricated with Co2Fe6B2/MgO based perpendicular-magnetic-tunneling-junction spin-valves on 12-in. TiN electrode wafers. Jex peaked at a certain Ru spacer-thickness: speci…
There is currently considerable interest in processes associated with the modification of germanium surfaces due to their potential application in electronic components such as MOSFETs. In this work, we combine first-principles total energy and reaction path calculations to study the initial stages of the oxidation of…
We present optical investigations of hybrid plasmonic nanosystems consisting of lithographically defined plasmonic Au-waveguides or beamsplitters on GaAs substrates coupled to proximal self-assembled InGaAs quantum dots. We designed a sample structure that enabled us to precisely tune the distance between quantum dots…
Spatially propagating reaction waves are central to a variety of energy applications, such as high temperature solid phase or combustion synthesis, and thermopower waves. In this paper, we identify and study a previously unreported property of such waves, specifically that they can generate temperatures far in excess…
We report alloying-induced and field-induced ferromagnetism in the $\ensuremath{\eta}$-carbide-type compound ${\mathrm{Fe}}_{3}{\mathrm{Mo}}_{3}\mathrm{N}$, which shows a non-Fermi-liquid behavior in the vicinity of a ferromagnetic quantum critical point. Co substitution induces ferromagnetism in ${(\mathrm{Fe}}_{1\en…
