System with Variable Energy, Volume and Number of Particles: Evaluation of Partition Function and Thermodynamic Quantities
(Pleiades Publishing, 2011)
Partition function and thermodynamic parameters of the system open with respect to energy E,
volume V and number of particles N, whereas temperature T, chemical potential μ and pressure P were kept
constant, were considered ...
Surface Modification of Aqueduct Ceramics Induced by Nd:Yag Pulsed Laser Treatment
(Philadelphia, PA, USA: Old City Publishing, Inc, 2017)
The main aim of this paper is to present the results of the morphological and chemical changes on the surface of a ceramic sample irradiated by the Nd:YAG laser. The tested sample is a part of an aqueduct tile, originating ...
Uticaj gama zračenja na molekulsku masu i staklasti prelaz PLLA / The Structure and Glass Transition Behaviour of PLLA under the Influence of Gamma Radiation
(Association of Chemical Engineers of Serbia, 2010)
U ovom radu ispitivan je uticaj gama zračenja na molekulsku masu i staklasti prelaz poli-L-laktida (PLLA). S obzirom da je PLLA pri izlaganju visokoenergijskom zračenju sklon kidanju lanaca i velikoj degradaciji, promene ...
Ruby laser beam interaction with ceramic and copper artifacts
(Springer, 2010)
Preventive care, research, and restoration of cultural heritage objects requires multidisciplinary research and the involvement of experts of different profiles, using high technology equipment. Nondestructive methods ...
The influence of the heat-treatment regime on a fracture surface of Nickel-based supperalloys / Vpliv toplotne obdelave na površino preloma superzlitin na osnovi niklja
(Inštitut za kovinske materiale in tehnologije, 2012)
Nickel-based superalloys are distinguished from other materials by their excellent mechanical and physical properties. As they are used at high temperatures and pressures, as well as in aggressive environments, their ...
Analiza praga oštećenja bakra i aluminijuma u interakciji sa rubinskim laserom / The analysis of damage threshold in ruby laser interaction with copper and aluminium
(Association of Chemical Engineers of Serbia, 2010)
U radu su prikazani rezultati delovanja laserske svetlosti, talasne dužine λ = 694,3 nm (rubinski laser, Q-switch mod), na uzorke od bakra i aluminijuma. Cilj ispitivanja je bio da se odrede maksimalne gustine energije ...
Solvent, structural, quantum chemical study and antioxidative activity of symmetrical 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides
(Springer, 2018)
15 symmetric 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides were synthesized in this work. Their structures were characterized using IR, H-1 and C-13 NMR, and UV-Vis spectroscopy. DFT calculations indicated ...
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 ...
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 ...
