A new optical channel drop filter was proposed based on two-dimensional (2D) 45° photonic crystal ring resonators. Its spectral information including intensity, dropped efficiency and quality factor affected by different physical parameters were numerically analyzed with 2D finite-difference time-domain technique. Nea…
Stvaranje uzorka dopadljive tkanine kreativna je djelatnost. Iako postoje racunalni programi namijenjeni pomoci pri stvaranju uzorka tkanine, oni nisu od pomoci u najvažnijem, kreativnom dijelu postupka. U namjeri da se pomogne u tom kreativnom dijelu postupka, razrađen je automatizirani postupak koji pomocu evolucijs…
Protein structural integrity and flexibility are intimately tied to solvation. Here we examine the effect that changes in bulk and local solvent properties have on protein structure and stability. We observe the change in solvation of an unfolding of the protein model, melittin, in the presence of a denaturant, triflu…
The purpose of this paper is to find the efficiency of window shades regarding building energy performance and explore the possibility of developing a model that enables users to find proper shades for their specific conditions. The paper investigates different options of shades and their related variables and finds t…
The title topic highlights several important concepts in physical chemistry: chemical equilibrium, thermodynamics of ion solvation, ideal and non-ideal solutions and solubility of salts. Furthermore, the selection of pedagogically novel example (a single, highly soluble salt) emphasizes mutual links and relative roles…
Die Werkzeugverschleisproblematik in der Umformtechnik verscharft sich durch den vermehrten Einsatz von hochstfesten Blechwerkstoffen und Rapid Tooling (RT) Technologien. Unerwarteter vorzeitiger Verschleis an den Werkzeugaktivelementen induziert zusatzliche Kosten durch Instandhaltungsmasnahmen. Dies fuhrt zur Notwen…
In this chapter we consider the trophic state and ambient nutrient limitation by the trophic index (TRIX) calculation and nutrient enrichment bioassay using the unicellular marine diatom Phaeodactylum tricornutum at two differently eutrophicated NE coastal Adriatic locations (in the Rijeka Bay area). The first locatio…
As the applications of circular polarization (CP) antennas are widely used in the wireless communications, it is significant to improve the CP antenna performance in aspect of axial ratio at the boresite direction. A good CP performance is always desired. In this paper, we fabricate the amendatory one-dimensional phot…
Stresses applied to ductile alloys or pure metals may induce severe plastic deformation with multiplication of defects and dislocations in their crystal networks. Such a disorder in the microstructure can influence the surface reactivity of the alloys, with consequences for their behaviour in corrosion. Here, cast pur…
The upconversion fluorescence spectra of Er3+/Yb3+: PLZT exciting at 980 nm were measured from 10K to 320K. A model for the dynamics of frequency upconversion processes was proposed. Based on the model, the upconversion luminescence intensities curves as a function of temperature were fitted and the temperature charac…
Collagen fibrils were regenerated from type I collagen solution (3 mg/ml, pH3.0). The mass of the regenerated collagen fibrils was measured using a QCM, and the microstructure of the fibrils was observed using an AFM. Under the condition (pH8.1, 37℃), the mass of the regenerated fibrils was maximum, and the period of…
The performance of 650nm RCLEDs including 34-pair AlGaAs/AlAs n-type DBRs and different pairs of AlGaInP/AlInP p-type DBRs have been investigated both theoretically and experimentally. The experimental results demonstrate that the device of optimized DBR mirrors with 10-pair p-type DBRs obtain high efficiency, low tur…
The process of nanosphere lithography was developed and applied to LED epistructure. We demonstrated p-i-n nanorod LED arrays with some specific characteristics. Moreover, LEDs encompassed with self-aligned nanorods are fabricated. Light diffraction behaviors are characterized. The results are explained by photonic cr…
Rice husk activated carbons (RHACs) supporting CuO at 6.3 and 12.5 mass% were tested to remove sulfur compounds of benzothiophenes (BTs) and dibenzothiophenes (DBTs) from commercial kerosene. The adsorption isotherms of RHACs for those sulfur compounds were obtained in a batch-mode. Fixed-bed flowing tests were also c…
In the frame of the TACIS Nuclear Safety program the European Commission sponsored a 24 months project defined together with Concern Energoatom (previously Rosenergoatom) and aiming at helping the nuclear plant operator improving its capabilities in the specific field of plant decommissioning. The 2 year project named…
Safety of fresh produce has been a perennial issue for the industry in the US despite tightening up regulations and implementing good manufacturing practice. The diversity of crops and labor-intense operations in the fresh produce production created a unique set of contamination routes that are not common in other foo…
The conduct of micro-blasting on PVD films for improving the cutting performance of coated tools is often encountered in industry. In the present paper, the effect of micro-blasting procedures on film mechanical properties, cutting edge geometry and thus on tool life is introduced. A novel method for enabling the dete…
This paper describes the fatigue behavior of the electrolytic Ni-plated AZ31-Mg alloy in laboratory air and in the corrosive environments (3% NaCl solution and purified water). Fatigue lives, crack initiation and propagation behavior were studied in detail to clarify the fatigue mechanism of the plated specimens. In t…
The ricochet of eroding long rods, from steel targets, is investigated by a series of three-dimensional numerical simulations in explicit finite element code. These are compared with the predictions of our analytical model and experimental results for ricochet. This approach is different than the rigid body treatment…
Notched compact tension specimens of SUS304 stainless steel (notch tip radius of 1mm and thickness of 6mm) were low cycle fatigued (stress ratio of -1) at RT in H_2 gas and in Pure air at 0.1Hz. Fatigue crack length of 2-3mm on the notch root surface was observed at number of cydes N=〜700 in Pure air and at N=〜200 in…
