A Janus nanoparticle is a unique anisotropic nanoparticle which typically has two or more distinct surfaces, each with different properties. In the present study, we performed molecular simulations to investigate the morphologies and phase diagrams of self-assembled diblock and triblock Janus nanoparticles confined in…
In some processes for spinning synthetic fibers the filaments are exposed to highly turbulent air flows to achieve a high degree of stretching (elongation). The quality of the resulting filaments, namely thickness and uniformity, is thus determined essentially by the aerodynamic force coming from the turbulent flow. U…
This paper presents a novel machine start-up technique for SOFC hybrid system based on a re-compression approach. This approach shows the reality of operating the system without the manufacturer’s usual technique of using the standard control system. A hybrid system emulator rig located at Savona, Italy will be used f…
A new, highly effective accelerating additive, based on copper silicate hydrates, has been developed to promote the early hydration of portland cement. Different cement paste samples, with and without the additive, were investigated at different times of hydration by a number of techniques, including electron microsco…
In recent years, demand for launch of the rockets has increased from space development. Although the solid propellant rockets relatively reasonable, it is difficult to safely manufacture a large of solid propellant, and the manufacturing process is non-constant. Therefore, we consider it is more reasonable if it is po…

Penelitian ini bertujuan untuk mengetahui pengaruh variasi komposisi nikel Superalloy terhadap sifat fisik dan mekaniknya serta mengetahui komposisi Superalloy yang dapat digunakan sebagai bahan pembuatan turbine blades pesawat terbang. Penelitia…
The aim of thesis is identification, risk analysis and and following design of technical modification and procedures on field of the low-level mixed wastes treatment. In the first part of the thesis is provided short discusses repository requirements for solidificated wastes in Czech republic. Next are described metho…
The aim of the present study is to investigate the potential of an aliphatic-aromatic copolyester PBAT as an alternative biomaterial for bone tissue engineering applications. To this end, 2D and 3D PBAT scaffolds were fabricated via different methods. Fabricated scaffolds were characterized and their cell promotion we…
Achieving the enhanced optical properties of rare earth doped inorganic glasses by embedding metallic nanoparticles (NPs) is ever-demanding in photonics. Optimized doping of NPs and subsequent thorough characterizations for improved absorption and emission are the key issues for lasing glasses. We inspect the influenc…
This study aims to analyze the changes of impact properties in fine grained steel after welding process. Two kind of steel were used, first one was S 355N steel and second one was Domex 700MC. Both of that steels are the type of steel with an improved yield strength and are suitable for light weight construction parts…
When high-frequency circular vibration is applied to a micropillar in fluid, flow is generated around the micropillar. In this research, we propose an innovative system of oocyte transportation by using vibration-induced flow. It is integrated on a chip with on-chip probe and force sensor for mechanical characterizati…
The article dwells upon the model of optimization of the fleet of snowplows for winter maintain of the urban road network, taking into account the probability characteristics of the intensity of snowfall in a certain territory. As an optimal criterion there are taken minimal total costs in the transport sector and to…

Ionic polymer-metal composite (IPMC) is a low-voltage driven soft actuator, and it can be also used as a sensor. In this report, we consider the possibility of the simultaneous use of IPMC as the sensor and actuator. In this report, we propose the similar method to measurement the strain by the strain gage as sensing…
To Find wear behavior of steel SAE1117 specimen .Specimens of diameter 12 and length 25 mm were cut of SAE 1117 material and subjected to different heat treatment procedures like carburizing, carbonitriding and liquid nitriding were prepared for microstructural analysis. The samples were etched using 3% natal (3% conc…
The objective of this study is to investigate the effect of acid hydrolysis time on microcrystalline chitin (MCC) filled polylactic acid (PLA) biocomposites using solution casting method. MCC was produced from commercial chitin using controlled hydrolysis process at four different hydrolysis time; 15, 30, 45 and 60 mi…
SMA actuators have light-weight and big power, and especially their powers and strengths of thickened it are increased and then Self-sensing control become more difficult by their electric resistance decreased. SMA actuators have big force to weight ratio. When it is heated and the temperature reaches the transformati…
The thesis is devoted to solving scientific problems of improving the reliability of construction schedules through improved planning methods and choice of rational management modes. The aim is establishing the impact of organizational and technological solutions at the stage of planning and management process to achi…
In this report, the characteristics of Pd/Al2O3 catalyst after long-term stability tests in catalytic combustion of simulated ventilation air methane gas were investigated with the objective of understanding catalyst deactivation phenomena. It was found that the deactivation is primarily due to palladium migration and…
The metal hydride heat pump (MHHP) is one of the options for its great potential in recovery of low-grade heat. However, due to the low effective thermal conductivity (ETC) of metal hydrides (MH) particle bed, MHHP shows low performance. In order to enhance the activation characteristic of MHHP, Aluminium Foam (A.F.)…
