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 ...
Anisotropy in Thermal Properties of Single Crystal α Quartz Obtained by the Photoacoustic Method
(The Japan Society for Analytical Chemistry, 2001)
Anisotropy in the thermal properties in α SiO2 single crystals SC cut mode 1 and mode 2 was investigated using the photoacosutic (PA) frequency transmission technique. The PA amplitude and phase diagrams were measured and ...
Thermoelastic and Electronic Deformation Components of Photoacoustic Signal in Two-layer System
(The Japan Society for Analytical Chemistry, 2001)
A model was derived in order to study the dependence of the photoacoustic signal on the thermal, elastic and carrier
transport properties of two-layer samples. The various systems were considered: the conductor-semiconductor, ...
Some Thermal and Electronic Transport Properties of YBa2Cu3O7-x Obtained by the Photoacoustic Method
(The Japan Society for Analytical Chemistry, 2001)
The possibility of simultaneous determination of some thermal and transport properties of polycrystalline YBa2Cu3O7-x, using a photoacoustic (PA) method was investigated. Both the amplitude and phase PA signals were measured ...
Photoacoustic Investigation of Anisotropic Thermal and Transport Properties of Single Crystal InSb
(The Japan Society for Analytical Chemistry, 2001)
Anisotropy of the thermal properties of single crystal InBi was investigated using the photoacoustic (PA) frequency transmission technique. Both PA amplitude and phase diagrams were measured and numerically analysed for a ...
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 ...
Anisotropic grossular-andradite garnets: Evidence of two stage skarn evolution from Rudnik, Central Serbia
(Earth Science Institute of the Slovak Academy of Sciences, 2021)
This paper presents LA-ICP-MS data for garnets from the Rudnik skarn deposit (Serbia), which range from Grs45–58Adr40–52Alm2–3 in the core and Adr70–97Grs2–29Sps1 in the rim displaying anisotropy and zoning. In spite of ...
Structural dissymmetrization of optically anisotropic Grs64±1Adr36±1Sps2 grandite from Meka Presedla (Kopaonik Mt., Serbia)
(Cambridge University Press, 2020)
In this paper, grandite core with Grs64±1Adr36±1Sps2 composition was crystallographically studied. This core represents zone A of the macroscopically visible five A–E zones of the optically anisotropic Grs58–64Adr36–42Sps2 ...
Laying the ghost of twin paradox
(Society of Thermal Engineers of Serbia, 2009)
Someone's true age is not written in his ID, but in his biomarkers. Aging process is not caused by time passing, but by thermodynamically laws. Entropy, extent of metabolic reaction, and temperature are Lorentz invariant, ...
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 ...
