In order to improve the tensile properties, crosslinking agent was added to PLA/PBAT polymer alloy. We compared the effect of the powder type and liquid type crosslinking agent. Also the tensile properties of PLA/PBAT specimens were measured using split Hopkinson pressure bar method at high strain rates.
Results of this study are presented in three sections: In the first section, the correlation between mechanical stiffness and heat transport along the solid framework is theoretically investigated.Hereby, structural modelling of highly ordered and of statistically isotropic porous materials is considered for correlati…
In this paper to improve the ionic conduction properties, lanthanum silicate apatite La9.33(SiO4)6O2 ceramic, which substituted by V ions at Si-site, were fabricated by the mixed-oxide method. And we investigated the structural and electrical properties of La9.33(Si6-□v□)6O26 specimens with variation of dopants for th…
In this work, Ni doped activated carbon aerogels were prepared by using KOH activation of carbon aerogels and nickel nanoparticles deposition to improve hydrogen storage capacity. The presence of Ni particles on activated carbon aerogels was investigated by X-ray photoelectron spectroscopy. The pore structure and spec…

Bereits seit einigen Jahrzehnten steht Magnesium im Fokus der Medizintechnikforschung im Bereich der bio-resorbierbaren Implantatmaterialien. Neben den Eigenschaften, die Magnesium für die Anwendung als Implantatmaterial auszeichnen, besteht jedoch nach wie vor das Problem der anfänglich starken Auflösung von Magnesiu…
В настоящей работе поставлена задача исследования реологических свойств \nмодифицированных по химическому составу сплавов циркония систем Zr – Nb и Zr – Nb – Sn \nприменительно к условиям различных процессов обработки металлов давлением (ОМД) при \nпроизводстве труб и прутков. Для этого были выполнены комплексные плас…
In this thesis, we focus on the effect on device performance by varying positions of nitrogen in carboline compounds—the host materials for blue phosphorescent organic light emitting diodes. The triplet energy level of carboline compounds is higher than carbazole in common use, meaning that different positions of nitr…
The ductile-to-brittle transition behavior of two austenitic Fe-18Cr-10Mn alloys with the combined addition of nitrogen and carbon was investigated in this study. The alloys exhibited a ductile-to-brittle transition behavior because of unusual brittle fracture at low temperatures unlike conventional austenitic alloys.…
A liga ternaria de Co-W-P foi eletrodepositado e otimizado com relacao aos parâmetros operacional e de banho (densidade de corrente e pH) em relacao a sua resistencia a corrosao. O desenvolvimento de banhos estaveis com niveis de pH relativamente baixos e a utilizacao de agentes complexantes para estabilizar e crucial…
The successful synthesis of a family of donor-iridium complex-acceptor triads (T1–T6, pMV1 and mMV1) and their electrochemical and photophysical properties were presented in this work. Triarylamines (TAA) were used as donors and naphthalene diimide (NDI) as acceptor. A bis-cyclometalated phenylpyrazole iridium dipyrri…
We describe a single step route for the synthesis of MoS₂ wires using a chemical vapour deposition (CVD) method. By tuning the CVD growth parameters, the horizontally oriented MoS₂ nanowires on SiO₂/Si substrate can be synthesized successfully. The MoS₂ nanowire has height of about 93 nm and width of about 402 nm with…
The large quantities of the petroleum-based foam materials used have raised concern due to their negative effects on the environment, predominantly single-use articles in packaging applications. Thus, considerable efforts have been put forth to develop environmentally friendly alternatives and, in particular, starch f…
O objetivo deste trabalho é avaliar a influência do tipo de poliolefina e da razão de sopro (RS) nas propriedades físicas e térmicas de filmes produzidos em processo de extrusão tubular. No processamento foram utilizados um polietileno de baixa densidade (PEBD) e um polietileno de alta densidade (PEAD) transformados n…

In this thesis the syntheses and detailed investigations on two foldable PBI systems were presented. The reversible, solvent-dependet folding/unfolding-behavior was used to study the ground and excited states properties of folda-dimer and folda-trimer by means of different spectroscopic methods as well as theoretical…
On the basis of physical and chemical analysis of the phase diagram of carbon the thermodynamic conditions and technological parameters of synthesis of nanomaterials obtained from detonation nanodiamonds have been investigated.According to the study of the topological model is confirmed that the synthesis of diamond m…
An important study of the solubility of hydrogen in α-phase PdH[subscript x] and deuterium in α-phase PdH[subscript x] over a wide temperature range was published by Clewley et al. (J. Chem. Soc., Faraday Trans. 1: Phy. Chem. Condensed Phases 69 (1973) 449–458). An analysis of the data based on an empirical solubility…
Beton memadat sendiri (Self Compacting Concrete, SCC) merupakan beton yang mampu mengalir sendiri dan dapat dicetak pada bekisting dengan penggunaan alat pemadat yang sedikit atau alat pemadat sama sekali. SCC mempunyai kelemahan dalam memproduksinya, dibutuhkan workability dan kohesi yang tinggi secara bersamaan. Unt…
Firstly, batch soda pulping of rapeseed straw (species Brassica napus L. convar. napus) was conducted without and with addition of anthraquinone as a catalyst in the cooking liquor. To characterize the chemical composition of rapeseed straw, cellulose, holocellulose, lignin, ash, and extractives were determined. For s…
