To evaluate defects on extreme ultraviolet (EUV) masks in the blank state of manufacture, we developed a micro-coherent EUV scatterometry microscopy (micro-CSM) system. Its illumination source is coherent EUV light with a 230 nm focus diameter on the defect using a Fresnel zoneplate. This system directly observes the…
The subject of this paper is the rigorous derivation of reduced models for a thin plate by means of Γ-convergence, in the framework of finite plasticity. Denoting by ε the thickness of the plate, we analyse the case where the scaling factor of the elasto-plastic energy per unit volume is of order ε2α−2, with α ≥ 3. Ac…
The ionic compounds that are used as electrode materials in Li-based rechargeable batteries can exhibit polar surfaces that in general have high surface energies. We derive an analytical estimate for the surface energy of such polar surfaces assuming charge redistribution as a polarity compensating mechanism. The pola…
An organic compound 1 based on a chromone fluorophore was synthesized and processed into organic nanoparticles (ONPs) N1 through a reprecipitation method. The photophysical properties of the organic nanoparticles were evaluated through UV-vis absorption spectroscopy, and these ONPs selectively recognize cyanide ions i…
We have investigated the positron-stimulated desorption of ions from a ${\text{TiO}}_{2}(110)$ surface. Desorbed O${}^{+}$ ions were detected in coincidence with the emission of annihilation $\ensuremath{\gamma}$ rays. The energy dependence of the ion yields shows that the O${}^{+}$ ions were detected at energies much…
The complete chloroplast genome sequence of Chlorella sorokiniana strain (SAG 111-8 k) is presented in this study. The genome consists of circular chromosomes of 109,811 bp, which encode a total of 109 genes, including 74 proteins, 3 rRNAs and 31 tRNAs. Moreover, introns are not detected and all genes are present in s…
In this paper, we investigate the dynamic aspects of the molecular recognition between a small molecule ligand and a flat, exposed protein surface, representing a typical target in the development of protein-protein interaction inhibitors. Specifically, we analyze the complex between the protein Fibroblast Growth Fact…
A novel type of integrated refractive-diffractive varifocal membrane lens is designed and analyzed by wave-optical methods. In contrast to other hybrid devices, the diffractive microstructure is directly imprinted onto the soft deflecting membrane, allowing for a high level of integration. Elastic deformation is taken…
The behavior of the electromagnetic field interaction with gold nanotriangles organized in bow-tie arrays is investigated. A side-by-side comparison between the measured absorbance of the array and the modelled integrated electric field resonances confined around the gold structures is presented and discussed to expla…
Abstract Flexible ethylene propylene diene monomer (EPDM)-titania nanocomposites of different compositions were prepared by room temperature mixing using both neat and annealed titania. All these composites showed composition-dependent dielectric and mechanical properties, and composites with controlled dielectric pro…
Purpose – The main aim of this study was to improve current efficiency and to obtain thicker coatings via aluminum oxide (Al2O3) addition to the chromium (Cr) (III) bath. Design/methodology/approach – Pure Cr and nanocomposite Cr–Al2O3 coatings were electrodeposited from Cr (III) bath onto cathode copper substrates by…
We theoretically investigate the finite size effect in quantum anomalous Hall (QAH) system. Using Mn-doped HgTe quantum well as an example, we demonstrate that the coupling between the edge states is spin dependent and is related not only to the distance between the edges but also to the doping concentration. Thus wit…
The electronic properties of quasi-one-dimensional anatase ${\mathrm{TiO}}_{2}$ nanostructures, in the form of thin nanowires having (101) and (001) facets, have been systematically investigated using the standard, hybrid density functional and quasiparticle calculations. Their visible photoabsorption characteristics…
The origins of residual stress gradients in nanocrystalline thin films, especially the role of grain size and texture gradients, are still not fully understood. In this work, the stress evolution in exemplary nanocrystalline TiN thin films with one and two fiber texture components as well as in homogeneous amorphous S…
As the most important binding phase of cement paste, calcium silicate hydrate can determine the mechanical properties of cementitious materials. Structural, dynamic and mechanical properties of calcium silicate hydrate gel at the colloid level (∼15 nm) were investigated for the first time in light of molecular dynamic…
The aim of the study is in vitro investigation of the feasibility of surface-modified bacterial nanofibrous poly [(R)-3-hydroxybutyrate] (PHB) graft for bladder reconstruction. In this study, the surface of electrospun bacterial PHB was modified with PEG- or EDA via radio frequency glow discharge method. After plasma…
This work discusses the influence of synthesis conditions on self-assembly capability and morphology of obtained Ag–Fe 3 O 4 nanoheterostructures. Samples were synthesized in two steps: first silver nanoparticles were synthesized and then used as seeds for the growth of iron oxide nanoparticles in a second step. The s…
As the only country in history to have created, then voluntarily renounced, a nuclear arsenal, South Africa is often referenced as a potential model for nuclear disarmament. However, this article argues that there are sharp limitations on the extent to which the South African case can be applied as a model for other c…
Strain engineering is ubiquitous in the design and fabrication of innovative, high-performance electronic, optoelectronic, and photovoltaic devices. The increasing importance of strain-engineered nanoscale materials has raised significant challenges at both fabrication and characterization levels. Raman scattering spe…
Japan Atomic Energy Agency (JAEA) has designed and developed high-temperature gas-cooled reactor (HTGR) hydrogen cogeneration system named gas turbine high-temperature reactor (GTHTR300C) as a commercial HTGR. Helium gas is used as the primary coolant in HTGR. Helium gas is easy to leak, and the primary helium leakage…
