Synthesis of calcium doped phosphate tungsten bronze
(Society of Physical Chemists of Serbia, 2018)
A study is presented of phase transitions of acid CaHPW12O40∙6H2O salt of 12-tungstophosphoric acid and characterized in the temperature range from room temperature to 1093 K. The structure and its phase transformations ...
There are two twin shadows, but Einstein is one!
(Society of Thermal Engineers of Serbia, 2012)
2011 is the international year of chemistry, and it is exactly 100 years past after the P. Langevin promotion of “twin paradox” problem. The hundred year old problem still demands its solution. Twin paradox, established ...
Characterization of natural raw materials in the processing of iron ore from Omarska mine
(Beograd : Rudarski institut Beograd / Belgrade: Mining Institute BelgradeBalkanska akademija rudarskih naukaAkademija inženjerskih nauka Srbije, 2017)
In present paper there were studied characteristics of the primary natural raw material samples from Omarska mine (Bosnia and Herzegovina). These materials are labeled as: “limonite ore”, “quartz” and “clay”, and they are ...
Particle size distribution of iron ore sludge determined by using different methods and iron content by size class
(University of Banja Luka Faculty of Mining PrijedorMining Institute Belgrade Ltd, 2017)
This paper presents the results of the study of the particle size distribution of the limonite sludge that occurs as a hydro-cyclone overflow in the Omarska iron mine. The primary role of the precise
characterization of ...
Living organisms from Prigogine’s perspective: an opportunity to introduce students to biological entropy balance
(Taylor & Francis, 2017)
All living structures, from archaea to human, are open thermodynamic systems analysed through nonequilibrium thermodynamics. Nonequilibrium thermodynamics is a field with important applications to life sciences, which is ...

U ovoj Doktorskoj disertaciji proučavano je pet različitih zona makroskopski zonarnog grandita sa lokaliteta Meka Presedla (Kopaonik, Srbija). Pomoću hemijske i elektronske analize mikroprobe preračunati su relativno visoko ...
Preliminary data on the crystal-chemical characteristics of beryl from Cer Mt. (Serbia)
(Carpathian-Balkan Geological Association, 2010)
A beryl crystal from Cer Mt. (Serbia) studied in this paper was characterized by means of XRPD and wet-chemical analyses. It has following unit cell dimensions: a = 9.2166(8) Å, c = 9.192(1) Å, V = 676.2(1) Å3 and ratio ...
Equation of state in form which relates mol fraction and molarity of two (or more) component thermodynamic system consisted of ideal gases, and it's applications.
(Society of Thermal Engineers of Serbia, 2010)
Most people would face a problem if there is a need to calculate the mole fraction of a substance A in a gaseous solution (a thermodynamic system containing two or more ideal gases) knowing its molarity at a given temperature ...
First occurrence of rodingite in Central Serbia
