(Institut za rudarstvo i metalurgiju Bor, 2015)
Cilj rada bio je komparativna karakterizacija elektrohemijskih prevlaka zlata dobijenih iz sveže sintetisovanog elektrolita, elektrolita nakon godinu dana od sinteze i elektrolita dobijenog rastvaranjem kristala komleksa ...
Modification of natural clinoptilolite and ZSM-5 with different oxides and a study of the obtained products in lignin pyrolysis
(Srpsko hemijsko društvo, Beograd, 2015)
In this work, different metal oxides (MO) supported on two types of zeolites: 1) natural clinoptilolite (NZ) and 2) synthetic zeolite, ZSM-5 were prepared and tested as catalysts in the fast pyrolysis of hardwood lignin. ...
Nimonic 263 microstructure and surface characterization after laser shock peening
(Croatian Metallurgical Soc, Zagreb, 2015)
The Laser Shock Peening (LSP) is applied to the surface of Nimonic 263 alloy. The changes in microstructure and surface topography are observed and analyzed by Scanning Electron Microscopy (SEM), profilometer and microhardness ...
Investigation of electrochemical behavior of anisomycin on gold electrode followed by HPLC-MS/MS analysis
(Elsevier Science Inc, New York, 2015)
Anisomycin is an immunosuppressant in low doses ( lt 0.1 mu M) with possible application in treatment of some autoimmune diseases and in inhibiting transplantation rejection. Anisomycin suppresses malignant tumor cell ...
Ni-pd/al(2)o(3) catalyst supported on reticulated ceramic foam for dry methane reforming
(Savez inženjera metalurgije Srbije, Beograd, 2015)
In the present study, Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam was prepared and evaluated in the dry methane reforming process. Corresponding metal chlorides were deposited to the foam surface by impregnation ...
Methacrylic Acid Based Polymer Networks with a High Content of Unfunctionalized Nanosilica: Particle Distribution, Swelling, and Rheological Properties
(Amer Chemical Soc, Washington, 2015)
The poor stability and tendency to agglomerate of unfunctionalized nano-SiO2 in the presence of ionic species presents a challenge for preparing poly(methacrylic acid)/nano-SiO2 nanocomposite (NC) hydrogels with desired ...
Optimisation of microwave-assisted extraction parameters for antioxidants from waste Achillea millefolium dust
(Elsevier Science Bv, Amsterdam, 2015)
Microwave-assisted extraction of polyphenols and flavonoids from waste Achillea millefolium (yarrow) dust was optimised using the response surface methodology. The influence of the extraction time (13-47 s), ethanol ...
In vitro conservation of cherry rootstock Gisela 5
(Natl Inst Science Communication-Niscair, New Delhi, 2015)
The paper presents results of the application of 'Cold Storage' (CS), a very simple in vitro technique preservation of cultures at +5 degrees C in total darkness. A protocol has been developed for in vitro preservation of ...
Comparative study of CeO2 nanopowders obtained by the hydrothermal method from various precursors
(Elsevier Sci Ltd, Oxford, 2015)
The effects of common precursors used in the synthesis of CeO2 nanopowders were investigated, and the structural and spectral properties of the resulting products were compared. Two cerium (III) salts, i.e., Ce(NO3)(3)center ...
Stress corrosion cracking resistance of aluminum alloy 7000 series after two-step aging / Otpornost aluminijumske legure serije 7000 prema naponskoj koroziji posle dvostepenog termičkog taloženja
(Association of the Chemical Engineers of Serbia, 2015)
The effect of one-step and a new (short) two-step aging process on the resistance to stress corrosion cracking of an aluminum alloy 7000 series was investigated, using slow strain rate test and fracture mechanics method. ...
