Purpose of this study was to determine the long term influence of the thermal power plant (TPP) Plomin in Istria peninsula (Croatia) on the possible contamination of the surrounding soil by the radionuclides from the emitted coal ash. Coal naturally contains radionuclides of the U-238 and Th-232 decay series, as well…
This study focus on the possibility of removing the basic textile dye Astrazon Blue FGGL 300% 03, from an aqueous solution, using Esmegel clay as adsorbent.The characterization of the adsorbent included the distribution of particle size, physical textural properties, chemical composition and determination of the point…
Abstract Tissue engineering seeks to restore the function of diseased or damaged tissues through the use of cells, biomaterials, and biologically active molecules. The next generation of functional tissue replacements will likely require additional exogenous stimuli to achieve many of the important requirements for lo…
A new series of rod-shaped mesomorphic compounds, 6-methyl-2-(4-alkoxybenzylidenamino)benzothiazoles bearing a fused thiazole ring and imine central linkage, were prepared and their molecular structures were confirmed via mass spectrometric, IR and NMR spectroscopic techniques. The mesomorphic properties were identife…
In this study, the concept of total material requirement (TMR) has been introduced to quantify the recyclability of scrap steel from end-of-life (EoL) vehicle. The TMRs for the recycling of scrap steels (urban ore TMR, UO-TMR) from the EoL vehicle have been estimated for four cases; conventional press-method, shredder…
In this paper, we use a phase field method coupled with the Navier-Stokes equations for numerical investigation of wetting phenomena.Simulations on capillary rise and droplet wetting on a flat substrate with fixed grids produce steady computational results in good agreement with analytical solutions and experimental d…
By using the density functional theory with B3LYP/6-31G+(d) we compute the optimization, vibration frequencies, electron structures of gg conformation of oligochitosans, and study the average binding energies and the zero-point energy corrections using WB97XD method. We also analyze the thermodynamic properties of oli…
Micro-porous layer (MPL) is a crucial component for an efficient water management in Polymer Electrolyte Membrane Fuel Cells (PEMFCs). Nowadays, MPLs are obtained by depositing a dispersion, commonly known as ink, containing carbon black particles and PTFE onto a carbon cloth substrate. In this work PTFE was replaced…
Plant-mediated synthesis of metallic nanoparticles is a growing area of interest in the fields of green synthesis and nanotechnology. The present work studied the synthesis of nano-gold particles using Tetradenia riparia flower, leaf and stem extracts derived using methanol and water. The synthesized nanoparticles wer…
Nanotechnology is a most promising field for generating new applications in medicine. The present investigation is highly warranted to through more light upon the Ag nanoparticles from medicinal plants will helpful to investigate the active principle action for biochemical and molecular fields. In this study, nanopart…
Wind power industry has shown a continuous technological improvement that has led to a structural scale up of the blades. The rotor has evolved in the last decades from a maximal diameter of 30 m at the beginning of the 1990s to 171.2 m in 2013. The bigger rotor allows to reach a far better effectiveness (1 MW compare…
Resistive-wall impedance usually constitutes a significant percentage of the total beam-coupling impedance budget of many accelerator structures (e.g. for LHC, it can be more than 50%). Reduction techniques for resistive-wall components entail high electrical-conductivity coatings. This paper proposes the use of metam…
UIT (Ultrasonic Impact Treatment)による高い疲労強度改善効果はいくつかの実験的研究により確かめられている．また，UITが疲労強度を向上させる要因は，止端形状改善よりも圧縮残留応力の導入にあることが知られている．鋼材静的強度を高くすることで，導入できる圧縮残留応力は高くなり，より高い疲労強度改善効果が得られると期待される． 本研究では，溶接継手の中でも疲労強度が低いとされる面外ガセット溶接継手を対象として，UIT処理を施した溶接継手の疲労強度に対する鋼材静的強度の影響について検討する．また，圧縮残留応力の効果のメカニズムを明らかにする目的で溶接止端に生じた疲労き裂の進展挙動と開閉口挙動についても検討す…
The adoption of micro- and nano- structured electrodes is a promising technique to improve the performance of Li-ion battery, which increases the electrode surface area and improves the efficiency of ion exchange between the electrode and electrolyte. This performance improvement is supported by the results of our num…
Summarizing the results of the investigations performed at IMSP RAS, the principles of producing a uniform ultrafine-grained structure in large-section billets, based on the technique of multiple isothermal forging, have been formulated. These principles imply a uniform introduction of plastic strain energy into large…
Abstract Porous heterostructures based on clay minerals are of great importance, especially in developing nanoporous materials with pre-designed properties, e.g. so that they can be used as alternatives to zeolites (as catalysts). Pillaring strategies have been applied for many years to prepare conventional pillared c…
Inclusions of nanosized ceramic particles in a polymer matrix influence the dielectric properties of their composite more when compared to conventional microcomposites through a greater interfacial contact area between the filler particles and the polymer per volume. This review summarizes the research of and potentia…
This paper discusses the use of oil palm shell (OPS) as lightweight aggregate in lightweight concrete especially in the structure application has been proven by previous researches. As industrial waste material, OPS can be the alternative material to be used in the construction industry. With its advantage as heat res…

In the present methodical study, FT-IR, FT-Raman and NMR spectra of the Propylbenzene were recorded and the fundamental vibrational frequencies were tabulated and assigned. The Gaussian hybrid computational calculations were carried out by HF and DFT (B3LYP and B3PW91) methods with 6-311+G(d,p) and 6-311++G(d,p) basis…
