For high-sensitive and specific protein sensing using graphene field-effect transistors (G-FETs), the antigen-binding fragment (Fab), which is a component of conventional antibody, was functionalized onto the graphene surface. Since the height of the Fab is approximately 3 nm, the antigen-antibody reaction is expected…
The paper presents separated results of the anthropometric measurement performed within the scope of the compound technological project (STIRP) "Croatian Anthropometric System" (HAS) in the Republic of Croatia. The presented results apply to adult female population, whereby newly defined female body types taking accou…

One of the most important mechanisms used in sewing machines is the needle bar and takeup lever mechanism. Being almost the same in nearly all classical sewing machines, this mechanism enables sewing by allowing movement of the needle and pulling of the thread for stitch formation. This study deals with the design of…
The design and analysis of a cold trap proposed for use in the purification of circulated eutectic sodium potassium (NaK-78) loops is presented. The cold trap is designed to be incorporated into the Fission Surface Power-Primary Test Circuit (FSP-PTC), which incorporates a pumped NaK loop to simulate in-space nuclear…
Selective catalytic reduction (SCR) is the most potential method for removing marine NOx emissions by up to 95%. This paper presents the results of an investigation using vanadium (V) based catalysts doped by metals W (tungsten), Ce (cerium) and Ni (nickel) to improve the low temperature performance of an SCR for NOx…
A report in 2005 by the Atomic Energy Commission of Japan has stated an expectation to secure the prospect of putting fusion into practical use by the middle of 21st century. A roadmap based on this policy was developed in 2008. The roadmap consists of a breakdown list of works which has shown and categorized the R&D…
Localized surface plasmon resonance (LSPR) is of particular interest to enhance the limit of detection for spectroscopic techniques such as Raman and fluorescence via a surface enhancement from metallic nanostructures. In this study, using nanosphere lithography (NSL) technique, a series of gold nanostructures over gl…
To study the internal blast load, a lot of small scale internal blast experiments have been conducted. For those experiments, the influence of explosive density generally was not taken into account while it was simple to have slight density differences in application. To analyze the influence of explosive density on s…
Pb-based complex perovskites with Fe 3+ like Pb(Fe 2/3 W 1/3 )O 3 were found to be interesting because of their unique properties such as relaxor and magnetoelectric behavior. Pb(Fe 2/3 W 1/3 )O 3 is ferroelectric with ferroelectric Curie temperature T C between 150 and 200 K and at the same time is antiferromagnetic…
Nowadays, the applications of the electrical machines with permanent magnets become very common, because of the outstanding properties of these devices in comparison with the induction machines. PM machines do not indicate electrical losses with the field excitation, which means increasing of their efficiency. This is…
Abstract: Ab initio and density functional theory (DFT) calculations were carried out on the energetic propellant molecule 2,4,6-trinitro-1,3,5-triazine (TNTA) to understand its bond topology and its energetic properties using the theory of atoms in molecules (AIM). The DFT method predicts that the electron density ρb…
In this thesis, examination of polycrystalline organic based devices such as the Schottky diode and MOS capacitor is carried out. The data is interpreted in terms of a polycrystalline model based mainly on a conventional polysilicon model with slight modifications to fit the organic properties. A brief introduction to…

Chemically Bonded Phosphate Ceramics (CBPCs) is a composite based material formed in a manner similar to cements. CBPCs have shown to be a good structural material with excellent thermal resistance properties. They have also been shown to have potential as a radiation shield. By incorporating various powders into the…
In this study, Co-Mo/-Al 2 O 3 , Ni-Mo/-Al 2 O 3 and (Co/Ni)-Mo/-Al 2 O 3 metal oxides have been prepared by the sol-gel process using citric acid and calcined at 800 C for 5 h. Phases of synthesized materials were characterized with X-ray diffraction. Morphological analysis and elemental composition of oxides were de…
One of the major challenges in the design of atmospheric reentry vehicles is the optimization of the thermal protection system (TPS). During a reentry, the vehicle encounter severs heating and mechanical stress. A robust sizing is therefore essential to insure vehicle integrity and the mission success. In order to max…
Electron emission from clean tungsten tips has been investigated at different temperatures and applied electric field. Emission mechanism is analyzed on the basis of the Fowler-Nordheim (FN) model and a parameter extraction model based on elimination of field enhancement factor. The suggested extraction model of the p…
Single layer thin film capacitor structures were fabricated on the surface of low temperature co-fired ceramic (LTCC) substrates using sputter deposition. The capacitor structures had areas between ~10 4 μm 2 to ~10 6 μm 2 and featured ~200 nm Al or Pt electrodes with 150-1500 nm Al2O3 dielectric layers. Impedance ana…
In the past decade there has been a renewal of interest in studying the feasibility of thorium-based fuel reactors as a potential advanced fuel for Generation IV nuclear energy systems producing fewer minor actinides than in uranium based-fuel. 232Th is a better fertile material than 238U in thermal reactors because o…
