  • Preparation and characterization of nanostructured ferric hydroxyphosphate adjuvants

    pg(s) 308-311

    This article describes part of the results obtained during the development of a new generation of vaccine adjuvants based on nanostructured hydroxyphosphates of tunable composition and physicochemical characteristics. Colloidal gels of ferric hydroxyphosphates of various iron/phosphate ratios were prepared by precipitation techniques, sterilized by autoclaving and analyzed by transmission electron microscopy (TEM) and dark-field optical microscopy. The obtained materials were composed of a network of amorphous nanoparticles (<20 nm in size) that were aggregated into micron-sized structures in physiological saline. Preliminary adsorption experiments indicated the ability of the obtained materials to adsorb protein substances, which is an important prerequisite for their potential application as vaccine adjuvants and further optimization of the production process to achieve reproducibility of the physicochemical characteristics.

  • Experimental and simulation determination of friction coefficient by using the ring compression test

    pg(s) 316-318

    One of the main problems in the plastic deformation of materials is the determination of the coefficient of friction as well as the subsequent application of the simulation for comparative analysis. However forecasting process and matching between simulation and experimental data is still a problem. Causes of this are factors such as roughness, mechanical properties of the material, chemical composition, etc. which strongly influence the behavior of the material in the simulation of the process.

    In this study, an approach is proposed to determine the changeable coefficient of friction in the deformation process experimentally, taking into account implicitly the influence of surface roughness on the friction curves. For the comparative analysis between experiment and simulation of the process, the experimental data for objective assessment was introduced. Nevertheless, there are differences between experiment and simulation, which is most evident in high loads, using lubricants differing from more than 12 units for graphite lubricant, with more than 6 units with oil and with dry friction with 8 units.

  • Analysis of the point group of diamond crystal

    pg(s) 319-322

    The structure of the diamond is usually represented as two face-centered cubic cell with the same dimensions, which are shifted relative to each other by the value of +/-(1/4.1/4.1/4) That is eight different ways. However, in this case, there is a possibility of only two enantiomorphous centers, which have the same ф (hkl ) j . They do not affect on the reciprocal lattice, but allow to explain, for example, the presence of twins. The introduction of the concept of the scattering center of diamond shows that his point group is Fm3m with the full symmetry formula 3L44L3(4L3i)6L29PC, whereas the generally accepted model of the diamond structure does not correspond to such symmetry. For example, the L4 axis is missing, C is not at the origin of coordinates, there is only one L3 axis along the diagonal along which the sublattices are shifted, etc.

  • The role of RFID technology in the intelligent manufacturing

    pg(s) 326-329

    The manufacturing industry is facing high competitiveness from rivals and high demands from customers. Industry 4.0, as a new manufacturing paradigm, also imposes its demands. The main driver of Industry 4.0 is the development of new innovative technologies including information and communication technologies whose rapid development has given impetus to the development of automated data acquisition systems. The RFID technology is one of the key technologies for intelligent manufacturing that encompasses advanced information and manufacturing technologies. Although the RFID technology is used in Croatia (mostly for identifying persons, access control, payment control, etc.), there is no wider use of the RFID technology in the industry where the main problem of low competitiveness is caused by low levels of innovative capabilities and obsolete technological equipment. The EU strategic documents (e.g. Europe 2020, Digitising European Industry initiative) encourage the digital transformation of industry (with an emphasis on investment in technology and innovation). One of the goals of the Industrial Strategy of the Republic of Croatia 2014-2020 is to increase productivity. To achieve this goal and improve competitiveness it is necessary to increase the use of the RFID technology in industry as the basis for digital transformation.
    The goal of this paper is twofold: to present bibliometric literature review on the RFID technology, and to present advantages of the RFID technology in the context of intelligent manufacturing with reference to the case of Croatian economy.
