In the present study, we performed ex-situ measurements of the change in the crystal structure of the cathode material subjected to a charge - discharge cycle in a coin type cell fabricated for this purpose. The results of this study demonstrate that it is possible to perform ex-situ structural analysis by neutron dif…

At sufficiently low temperatures, electron spins in normal magnets generally order into some fashion, for instance, ferromagnetic and antiferromagnetic. Geometrical frustration and/or reduced dimensionality can suppress such conventional orders, and occasionally induce unknown states of matter. This is the case for th…
A significant increase in the research activity related to high manganese twinning induced plasticity (TWIP) steels has occurred during the past ten years, motivated by the breakthrough in its combination of strength and ductility. This researches were done to aid in the understanding of the mechanism of the alloy esp…

2.0 mu m spectroscopy of a new germanate-tellurite glass with Ho3+/Yb3+ codoping is synthesized and analyzed. Efficient 2.0 mu m emission of Ho3+ ions sensitized by Yb3+ ions from the host glass is observed under 980nm pumping. The maximum emission cross section of Ho3+ ions transition is 4.32x10(-21) cm(2) around 2.0…
Hydrogen (H) atoms and proton (H+) of biomacromolecules are important for various biological phenomena. H atoms of functional groups such as -OH and -NH2 make hydrogen bonds to contribute to folding and assembly of biomacromolecules. H+ ions are used for chemical reaction, electron transfer, and H+ concentration gradi…
Neutron inelastic scattering techniques, including quasielastic and elasitic incoherent neutron scattering, provide unique tools to directly measure the protein dynamics at a picosecond time scale. Since the protein dynamics at this time scale is indispensable to the protein functions, elucidation of the protein dynam…
An isothermal cure kinetics of vinyl-tri(phenylethynyl)silane ((ph-C=C)3-Si-C=CH2) (VTPES) was investigated by differential scanning calorimetry in the temperature range 345-370 C. The results showed that the shapes of the conversion curves were all similar and all of the cure reactions could be described by an autoca…

A lot of frustrated magnetic systems exhibit a nontrivial magnetic order, such as long-wavelength modulation, noncollinear, or noncoplanar order. The nontrivial order may pave the way for the novel magnetic function of matter. Neutron studies are necessary to determine the magnetic structures in the frustrated magneti…
This article reports the recent discovery of NaCl-type lanthanum monohydride using synchrotron radiation x-ray diffraction and neutron diffraction measurements under high pressure. We have found that fcc-LaH2 decomposes into two phases，which have different hydrogen compositions，the H-poor and H-rich phases，at 11 GPa a…
A composition is composed of a reinforcement and a matrix, which determine mechanical characteristics of the molded part. There is no doubt that the properties of a composites depend not only on the characteristics of the matrix but also on the structure of glass fiber mat and a fiber type of reinforcement. In this st…
We shall outline geometrical and algebraic ideas which appear to lie at the foundation of the theory of defective crystals that was introduced by Davini [5] in 1986. The focus of the paper will be on the connection between continuous and discrete models of such crystals, approached by consideration of the symmetries i…

We report chiral magnetic ordering in ferromagnetic inorganic compounds T1/3MS2 (T = Cr and Mn, M = Nb and Ta) with a chiral space group of P6322. We measured the magnetization, powder neutron diffraction and small angle electron diffraction experiments. The experimental results indicate formation of long periodic hel…
U sklopu zavrsnog rada na Tehnickom veleucilistu u Zagrebu napravljeno je ispitivanje fizikalno mehanickih svojstava ocvrsnulog betona. Istraživanje je provedeno na uzorcima kocke izrađenim od razlicitih mjesavina betona, pri cemu su koristene tri vrste cementa i dva superplastifikatora. Tlacna cvrstoca betona ispitan…
Impact load for Boeing 747-400 commercial aircraft was obtained with adequate scaling of wellknown dependencies of mass distribution (per unit length) and fuselage buckling load (per unit length) for Boeing 720 aircraft, which J.D.Riera received in 1968.The Boeing 747-400 impact load on a rigid barrier for different v…
This work on the processing and study of the indentation fracture composites of dual-metallic phase of Al-Si and dual carbide phase of B4C and SiC uses the reactive melt infiltration method to prepare nearly fully dense samples. Batches of single and twice smelted Al-Si alloys of hypereutectic composition were produce…
