We fabricated ordered GaN nanocolumns (NCs) with InGaN/GaN multiple quantum wells (MQWs) that emitted light at wavelengths of 590–600 nm by rf-plasma assisted molecular beam epitaxy. The NCs exhibited sharp emission with a full width at half maximum of 44–45 nm, and the internal quantum efficiency (IQE) was evaluated…
To systematically investigate high-temperature corrosion of superheaters in biomass combined heat and power (CHP) plants, a long-term test run (5 months) with online corrosion probes was performed in an Austrian CHP plant (28 MW NCV; steam parameters: 32 t/h at 480 °C and 63 bar) firing chemically untreated wood chips…
This paper reports an "all in one" procedure to produce mesoporous, micro-spherical LiFePO₄ composed of agglomerated crystalline nanoparticles. Each nanoparticle is individually coated with a thin glucose-derived carbon layer. The main advantage of the as-synthesized materials is their good performance at high charge-…
The translocation of polymer through a channel with a gradient interaction between the polymer and the channel is studied. The interaction is expressed by E = E0 + kx, where E0 is the initial potential energy at the entrance, x is the position of the monomer inside the channel, and k is the energy gradient. The mean f…
Plasticity plays a crucial role in the mechanical behavior of engineering materials. For instance, energy dissipation during plastic deformation is vital to the sufficient fracture resistance of engineering materials. Thus, the lack of plasticity in brittle hybrid organic-inorganic glasses (hybrid glasses) often resul…
Abstract magnified image The growth of self‐catalyzed InAs nanowires on Si(111) substrates via vapour–solid (VS) and vapour–liquid–solid (VLS) growth mechanisms is investigated using molecular beam epitaxy. For both mechanisms, the substrate preparation plays a crucial role. In this context, the required thin oxide la…
In this chapter the problem of elastic light scattering, i.e. interaction of electromagnetic waves with finite objects, is discussed. A detailed overview of one of the widely used methods for plasmonics, the discrete dipole approximation (DDA), is presented. This includes the theory of the DDA, practical recommendation…
The decarboxylation of brown grease (BG) to green diesel hydrocarbons over a 5 wt % Pd/C catalyst was investigated in semibatch and batch reactors. Catalytic deoxygenation of BG under H 2 –Ar occurs primarily via decarboxylation with the liquid products of primarily n -heptadecane and n -pentadecane. A 90% conversion…
The spatial switching of mid-infrared light near-fields is proposed in coupled graphene heterogeneous ribbon pairs. By using the coupled plasmon modes in graphene ribbon pairs, the electric near-field enhancement can be spatially controlled in graphene ribbons as the tuning of the external bias voltage difference. Mor…
To overcome the limitations of the conventional particle size reduction technologies, a novel combinative particle size reduction method for the effective production of homogeneous nanosuspensions was investigated. Ursodeoxycholic acid, a poorly soluble drug representative, was tried to prepare nanosuspension by homog…
We report enhanced solar cell performance using high-density InAs quantum dots. The high-density quantum dot was grown by antimony mediated molecular beam epitaxy. In-plane quantum dot density over 1 × 1011 cm−2 was achieved by applying a few monolayers of antimony on the GaAs surface prior to quantum dot growth. The…
Thin film capacitors on areas up to 6 mm2 have been measured regarding capacitance density, relative permittivity, and electrical breakdown. The maximum storable energy density of the thin film capacitors will be discussed as a parameter to evaluate the thin film capacitors applicability. Therefore the measurements of…
Diazadithia[7]helicenes were synthesized from the readily available building block ethyl 7-chloro-8-formylthieno[3,2-f]quinoline-2-carboxylate by a Wittig reaction-photocyclization strategy. The helicene core was functionalized by nucleophilic aromatic substitution with a variety of nucleophiles (e.g., O-, N-, and C-c…
A systematic study is conducted to reveal how far the polymeric vesicle wall can embed gold nanoparticles (AuNPs) with different sizes by combining experiments and self-consistent field simulations. Both the experimental and simulative results indicate that the location of AuNPs in vesicle wall or in spherical micelle…
An unusually large Kadowaki–Woods ratio of A/γ2 ∼ 43 μΩ·cm·mol2·K2·J−2 has been observed for intermetallic Mn1-xFexCoGe compounds in the proximity of x = 0.2 where the magnetic state of itinerant electrons system changes. The ratio is approximately four times larger than observed for heavy fermion systems. The manifes…
The rheological model, Huet model, which is composed of one spring and two power function elements, has two expressions: one in time domain, which is used for creep compliance, and one in the frequency domain, which is associated with complex modulus. Previous research efforts showed that the Huet model provides a ver…
This study investigates encapsulation efficiency of model drug, encapsulated by magnetic poly d,l-lactic-co-glycolic acid (PLGA) nanoparticles (NPs). This is the following part of our preceding paper, which is referred in this paper as Part I. Magnetic nanoparticles and model drug human serum albumin (HSA)-loaded PLGA…
The nanocomposite of TiO2-MWCNTs has been synthesised by simple hydrothermal route showing significant enhancement in the photocatalytic activity for the degradation of methyl orange dye (MO). Several characterisations employed were X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy-dispersive X-ray s…
BACKGROUND: We have previously proposed triosephosphate isomerase of Giardia lamblia (GlTIM) as a target for rational drug design against giardiasis, one of the most common parasitic infections in humans. Since the enzyme exists in the parasite and the host, selective inhibition is a major challenge because essential…
Docyanine green (ICG) and LHRH-PE40 fusion protein are tethered onto drug carriers of silica nanorattles for imaging-guided tumor-specific drug delivery and bimodal therapy. The synergistic therapeutic effect of toxin PE40 and the chemotherapeutic drug docetaxel (Dtxl), specifically directed by LHRH to cancer, improve…
