Foods may have both solid and liquid properties, and are described as viscoelastic products. Knowledge on such viscoelastic features is very useful for quality control and/or food stability. The purpose of this work was to evaluate the effect of the application of 1-MCP on the viscoelastic properties of minimally proc…
B-Zn-Si-Al compounds are modified Si-Al compounds made of sodium silicate, zinc sulfate, borax, and aluminum sulfate. They act as a fire retardant during the preparation of ultra-low density fiberboards (ULDFs). An orthogonal experiment was used to optimize the contents of the four compounds according to the limiting…
A new technique to reduce discretization errors for ray tracing in the method of characteristics (MOC) is proposed focusing on depletion calculations of single and multi-assembly geometries. In order to efficiently carry out depletion calculations, a calculation scheme using the superhomogenization (SPH) method can be…
High-resolution single crystal neutron diffraction measurements are presented probing the magnetostructural response to uniaxial pressure in the iron pnictide parent system ${\mathrm{BaFe}}_{2}{\mathrm{As}}_{2}$. Scattering data reveal a strain-activated, anisotropic broadening of nuclear Bragg reflections, which incr…

Both pictures published under Creative Commons Attribution-Share Alike 3.0 Unsorted. OLEDs from the ground up can be easily understood following the steps that led to the development of these…
Detailed total energy calculations have been performed in lutetium pnictides (LuX, where X = N, P) to understand their high pressure structural stability. In LuN, the ambient rocksalt type structure (B1 phase) transforms to a tetragonal structure (B10 phase) at ∼240 GPa; whereas in LuP the orthorhombic structure (B33,…
A corrosion monitoring system for steel using Fiber Bragg grating (FBG) sensors is proposed. FBG sensors were protected by hypodermic tubes and a layer of adhesive. The increase in volume caused by the presence of corrosion product introduces strain that can be monitored by FBG sensors. Experimental results showed a p…
Iron-doped TiO2 catalysts were prepared by impregnation in order to study their photocatalytic activity in the treatment of wastewater from the textile industry. Characterization of the catalysts before and after reaction was performed using techniques including total surface area measurement, X-Ray diffraction and el…
In the last few years, the combination of laser irradiation with atmospheric pressure plasmas, also referred to as laser–plasma hybrid technology, turned out to be a powerful technique for different materials processing tasks. This chapter gives an overview on this novel approach. Two methods, simultaneous and sequent…
Self-supporting membranes built entirely of carbon nanotubes have been prepared by wet methods and characterized by Raman spectroscopy. The membranes are used as supports for the electrodeposition of Pt nanoparticles without the use of additional additives and/or stabilizers. The Pt precursor is an ad hoc synthesized…
Remarkable electrical properties of carbon nanotubes (CNT) have lead to increased interest in studying CNT- based devices. Many of current researches are devoted to using all kinds of carbon nanomaterials in the con- struction of sensory elements. One of the most common applications is the development of high performa…
Various interacting lattice path models of polymer collapse in two dimensions demonstrate different critical behaviours. This difference has been without a clear explanation. The collapse transition has been variously seen to be in the Duplantier–Saleur θ -point university class (specific heat cusp), the interacting t…
A new solid-state composite was prepared by using fly ash as host matrix and carbon shoots of camphor as dispersoid, which are abundantly available and cheap. The composite was characterized by using different techniques. For conductivity and dielectric measurements, we used complex impedance spectroscopy. Maximum con…
Cartilage is one of the most important tissues in mammalian growth and is classified into three types: hyaline, fibro, and elastic. To illustrate its potential as a clinical diagnostic tool, nonlinear optical microscopy (NLOM) was applied to simultaneously investigate images and spectra from three different types of r…
Nanoparticle based drug products are of growing interest in the field of pharmaceutics. Enhancing saturation solubility and dissolution velocity by preparing drug nanoparticles correlates with faster absorption rates. The faster absorption rates can correlate into better bioavailability, reduction in fed and fast effe…
A series of superlattices consisting of 15 bilayers of ferromagnetic La0.7Sr0.3MnO3 (LSMO) and SrRuO3 (SRO) were grown with either stacking order on (1 1 1) oriented SrTiO3 (STO) substrates using the pulsed laser deposition technique. The Raman spectra of these superlattices show the existence of rhombohedral and orth…
Abstract Al x Ga1− x N layers with high aluminum content of x ∼ 0.68–0.73 were grown in an 11 × 2-in. AIX 2400 G3 HT planetary reactor by metal–organic vapor phase epitaxy. Growth trends are analyzed by reaction-transport modeling in a wide range of growth conditions. Gas-phase nucleation resulting in both Al and Ga c…
Techniques have been developed for making a unique type of piezoelectric thick-film strain sensor in the form of a ‘piezoelectric adhesive’ to be embedded into a bonded joint. Lead zirconate titanate (PZT) powder is used as the active ingredient of the piezoelectric composite and epoxy resin as the matrix. The sensors…
The first radical end-coupling synthesis of polydimethylsiloxane (PDMS)−γ-cyclodextrins (γ-CDs) based polyrotaxane is reported. Conversely to usual chemical way, the radical process leads to fast both controlled size and structure with minimal side reaction while exhibiting very high conversion rate (w/w, 80%). Pure P…
