The purpose of this research was to investigate the creep behaviour of the heterogeneous Timber-UHPFRC beams. New developments have been done to further improve the structural performance, such as strengthening of the timber (glulam) beam by bonding composite material combine with an ultra-high performance fibre reinf…
The Geant4 based ray-tracer used to support the development of Silicon Pore Optics is being extended to take into account more subtle effects that affect the performance of the optics, like thermo-mechanical stresses and detailed surface metrology. Its performance has also been increased to make it possible to simulat…
Abstract The thermokinetics of the curing reactions between poly‐(3‐azidomethyl‐3‐methyloxetane) (PAMMO) and bispropargyl succinate (BPS) were studied using a microcalorimeter. On the basis of experimental and calculated results, three thermodynamics parameters (the activation enthalpies, the activation entropies, the…
The field of biotechnology emerged in the fast pace of biology with the interface of science, engineering and technology and mostly known for its multidisciplinary nature. As we progress successively in this domain, the refinement of the field is quite obvious. Looking into an era of nanoscience and technology, now a…
I. Stratis In this work, we investigate the analyticity properties of solutions of Kuramoto–Sivashinsky‐type equations in two spatial dimensions, with periodic initial data. In order to do this, we explore the applicability in three‐dimensional models of a spectral method, which was developed by the authors for the on…
We report on the optical and electrical excitation of the modes of a “hybrid” waveguide consisting of a single organic nanofiber on a thin gold film. In the first set of experiments, light is used to excite the photoluminescence of an organic nanofiber on a thin gold film and the resulting emission is analyzed using F…
Addition of poly(acrylic acid-co-maleic acid) (PAAMA) during the synthesis of vanadium phosphates changes the morphology and improves the catalyst performance.
We report differential cross sections (DCSs) and integral cross sections (ICSs) for electron-impact vibrational-excitation of pyrimidine, at incident electron energies in the range 15-50 eV. The scattered electron angular range for the DCS measurements was 15°-90°. The measurements at the DCS-level are the first to be…
A series of Zn(II) porphyrins which have asymmetrically substituted meso groups have been studied with UV–vis, resonance Raman, emission spectroscopies, and density functional theory (DFT) calculations. Dye-sensitized solar cells (DSSCs) of these materials have also been fabricated and their performance parameters mea…
The aim was to develop a hybrid three-dimensional-tissue engineering construct for chondrogenesis. The hypothesis was that they support chondrogenesis. A biodegradable, highly porous polycaprolactone-grate was produced by solid freeform fabrication. The polycaprolactone support was coated with a chitosan/polyethylene…
We report on a theoretical study of the electronic structures of InSb and GaSb nanowires oriented along the [001] and [111] crystallographic directions. The nanowires are described by atomistic, tight-binding models, including spin-orbit interaction. The band structures and the wave functions of the nanowires are calc…
Ceramic thermal barrier coatings are being used in oil and gas industries, gas turbines and diesel engines. An atmospheric plasma spraying process is used to coat the ceramics on stainless steel grade 304 substrates. The salt spray (fog) test procedure was used to assess the corrosion resistance of ceramic-coated spec…
The radiated power enhancement (suppression) of an in- (out-of-) plane-oriented radiating dipole at a desired emission wavelength in the deep-ultraviolet (UV) range when it is coupled with a surface plasmon (SP) resonance mode induced on a nearby Al nanoparticle (NP) is demonstrated. Also, it is found that the enhance…
We consider a simple configuration for realizing one-dimensional slow-light metamaterials with large bandwidth-delay products using stub-shaped Fabry-Perot resonators as building blocks. Each meta-atom gives rise to large group indices because of a classical analog of the dressed-state picture of electromagnetically i…
Recent experiments have shown that the efficiency of photoinduced electron transfer from sensitizers (molecules or quantum dots) to semiconductors can be enhanced by coupling the sensitizers to plasmon resonances in metal nanoparticles. Here, we use a model-Hamiltonian approach to show theoretically that there is an o…
The molecular theory of adsorbate melting in slit pores or near planar open surfaces is generalized to the case of arbitrary pores with a random character of the spatial distribution of adsorption centers (a fully distributed model). The states of liquid and crystalline adsorbates with regard to the contributions from…
In the present study, the inorganic analogues of alkanes as well as their isoelectronic BN/CC counterparts that bridge the gap between organic and inorganic chemistry are comparatively studied on the grounds of static DFT and Car-Parrinello molecular dynamics simulations. The BN/CC butanes CH3 CH2 BH2 NH3 , BH3 CH2 NH…
To enhance the mechanical performance and ultraviolet shielding property, graphene oxide was incorporated as the functional nanofiller into a sodium alginate matrix to form a composite film via a solvent-casting method. The as-obtained films were characterized by scanning electron microscopy, Fourier transform infrare…
Solution processed thin film photovoltaic devices incorporating organohalide perovskites have progressed rapidly in recent years and achieved energy conversion efficiencies greater than 20%. However, an important issue limiting their commercialization is that device efficiencies often drop within the first few hundred…
Purpose – The purpose of this paper is to check an applicability of aluminized basalt fabrics for production of gloves protecting simultaneously against thermal and mechanical factors. Design/methodology/approach – Six variants of protective gloves were manufactured using two different glove constructions: more simple…
