Abstract Invited for the cover of this issue are the groups of Joel S. Miller at the University of Utah and Juan J. Novoa at the University of Barcelona. The image depicts a visualization of the energy difference between the new 2e−/6c and the established 2e−/4c bond for C2 and D2h conformations, respectively, for π‐[…
Surface plasmon resonance (SPR) sensing has become an undis-putable and still burgeoning, leading technology in the plasmonics field. The main benefits of SPR are label-free detection and studies of biological binding to the sensor surface. Determination of the SPR location with high accuracy is of major importance fo…
Basidiomycete’s fungi are used for biodegradation of azo dyes, which is mainly employed in textile, food and pharmaceutical industry. In addition they have some medicinal uses like anti-tumor effect due to their polysaccharide; they can reduce cholesterol level as they produce Lovastatin. They are rich in microelement…
In this Letter, we report the enhanced radiative recombination output from an AlGaAs/GaAs heterojunction bipolar transistor with InAs quantum dots embedded in the base region to form a quantum-dot light-emitting transistor (QDLET) grown by molecular beam epitaxy systems. For the device with a 100 μm×100 μm emitter are…
There is described a method of generation the rigid feature “Force – Settlement” for thin- layer rubber-metal compensating elements, which consist of several rubber and non-elastomeric layers, operating when being pressed, taking into account the low compressibility of rubber layers and deformation of support non-elas…
The paper analyses the possibility of alkali activated materials utilization as matrix for repair mortars, determined for rehabilitation of reinforced concrete structures, exposed to chemically aggressive surroundings. alcali activated materials have owing to their specific properties a high potential especially for u…
The influence of new complex nanodisperse admixture on structure and strength characteristics of fine grain concrete used in rehabilitation of damaged concrete structures has been studied. Concrete without the admixture is more susceptible to cracking than concrete with the complex admixture, thus increasing the worki…
The application of a high magnetic field is capable of inducing the formation of aligned equiaxed grains in alloys during directional solidification. The alignment and refinement of the grains is enhanced as the magnetic field intensity increases. The thermoelectric power difference at the liquid/solid interface in fo…
Abstract Rhodium‐carbon bond cleavage represents an essential step for small molecule activation and transformation by rhodium porphyrin complexes. This article reports on a new method for the cleavage of porphyrin rhodium(III)‐carbon bonds in DMSO solvent with strong bases. UV‐Vis, in situ 1H NMR spectrum and GC‐MS a…
Nuclear fission is one of the more popular and efficient sources of energy that has been used in the last few decades. In the setting of the ongoing worldwide debate of the energy problem, this paper will review the different types and generations of nuclear reactors, and do comparisons with other notable energy sourc…
We previously reported [Sci. Rep.4, 6077 (2014)10.1038/srep06077SRWSDA2045-2322] that the geometrical randomness of disk-shaped silver nanoparticles, which exhibit high reflection at near-infrared wavelengths, serves as the origin of a particle-dependent localization and hierarchical distribution of optical near-field…
It was recently shown that conventional phonon-electron interactions may induce a triplet pairing state in time-reversal invariant three-dimensional Dirac semimetals. Starting from the microscopic model of the isotropic Dirac semimetal, the Ginzburg-Landau equations for the vector order parameter is derived using the…
An observation of microstructure revealed that a laser-irradiated Nd-Fe-B target under the laser energy density above 10 J/cm2enabled us to prepare isotropic nano-composite thick-film magnets with good magnetic properties due to a dispersed α-Fe + Nd-Fe-B structure. The formation of the structure is attributed to the…
In order to obtain tunable surface modes of photonic crystal, we add a magnetic material layer on the truncated surface of a two-dimensional photonic crystal. Through calculations of photonic band, we obtain the surface defect modes in the first and second gaps. Through the modulation of applied magnetic field, we can…
Quantum dots (QDs) are a type of fluorescent label with applications in biological molecules, cells and in vivo imaging. The current study investigated the effect of QDs on the toxicity, proliferation, migration and invasion of the EJ human bladder cancer cell line in vitro. The cell counting kit‑8 test was used to me…
Biomass gasification followed by fuel synthesis is one of the alternatives for producing liquid fuels and chemicals from biomass feedstocks. The gas produced by gasification contains CO, H2, H2O, CO2, light hydrocarbons and tars. The light hydrocarbons can account for as much as 50% of the total en ergy content of the…
Abstract A comparative study of the dielectric relaxational behaviour of two structurally close polymers, containing aromatic side groups, was carried out in order to analyse how slight differences in the chemical structure affect the molecular responses to perturbation field. Specifically, poly(phenylpropyl acrylate)…
Ba0.6Sr0.4TiO3 thin films with a thickness of 339 nm are deposited directly on the high resistivity silicon through pulsed laser deposition. Coplanar waveguides with a slot width of 4.5 μm are designed to extract the complex permittivity of ferroelectric thin film in the frequency range from 1 GHz to 110 GHz. A fast t…
Abstract Bei der Herstellung von Zeolith‐Granulaten variieren der Bindemittelgehalt und die Temperaturen bei der Entwässerung und Aktivierung der Granulate. Hier wird der Einfluss der Feuchtebeladung und zyklischen Be‐ und Entfeuchtung auf die mechanischen Eigenschaften von drei Zeolith 4A Granulaten mittels Druckbean…
A microprobe system has been installed on the nanoprobe/XAFS beamline (BL8C) at PLS-II, South Korea. Owing to the reproducible switch of the gap of the in-vacuum undulator (IVU), the intense and brilliant hard X-ray beam of an IVU can be used in X-ray fluorescence (XRF) and X-ray absorption fine-structure (XAFS) exper…
