Analysis and interpretation of the micromechanical properties measurements of electrodeposited nickel coatings on different substrates.
(Belgrade : Academy of Criminalistic and Police Studies, 2020)
Fine-grained nickel coatings were electrodeposited by direct current (dc) regime onto different substrates: polycrystalline cold-rolled copper, polycrystalline brass and single crystal (100)-oriented silicon. These composite ...
Forced periodic reactor operation
(Max Planck Institute, 2020)
We used the nonlinear frequency response (NFR) method in order to identify forced periodic conditions under which the acetic acid anhydride hydrolysis (chosen as a test reaction) can be favorably performed in a CSTR. Based ...
SOLVATOCHROMIC STUDY OF NOVEL BENZYLIDENEHYDANTOIN AS A MOLECULAR PHOTOCHROMIC SWITCH / PROUČAVANJE SOLVATOHROMNIH SVOJSTAVA NOVOG BENZILIDENHIDANTOINA KAO MOLEKULSKOG FOTOHROMNOG PREKIDAČA
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2020)
Molecular photochromic switches represent an intriguing class of organic molecules that can
be reversibly interconverted between two stable states by light. The resulting change may be the
consequence of trans→cis ...
Prostorna raspodela i identifikacija elemenata i oksida u površinskom sedimentu Bokokotorskog zaliva / Spatial distribution and identification of elements and oxides in surface sediments of the Boka Kotor bay
(Beograd : Srpsko društvo za zaštitu voda, 2020)
Ovo istraživanje sprovedeno je u Bokokotorskom zalivu radi procene kvaliteta površinskog
sedimenata, a time i stanja morske sredine. ED-XRF metodom elementarne analize određen
je sadržaj velikog broja elemenata i oksida ...
Ekološka procena rizika u odnosu na teške metale u površinskomsedimentu Bokokotorskog zaliva / Ecological risk assessment of heavy metals in surface sediments of the Boka Kotor bay
(Beograd : Srpsko društvo za zaštitu voda, 2020)
Pored uticaja prirodnih i atmosferskih faktora, negativni antropogeni uticaj u području
jugoistočnog Jadrana je u porastu poslednjih decenija. Povišeni nivo teških metala akumulira
se u površinskom sedimentu usled taloženja ...
Response Surface Methodology and Artificial Neural Network-Based Models for Predicting Roughness of Cu coatings
(Belgrade: ETRAN – Society for electronics, telecommunication, computing, automatics and nuclear angineering, 2020)
Copper coatings are produced on silicon wafer by electrodeposition (ED) in pulsating current (PC) regime. Electrodeposition was performed at various current density amplitudes in the range of 80−140 mA cm-2, frequency in ...
Extraction of phenolic compounds from agro-industrial wastes and evaluation of their antioxidative potential
(Skopje : Consulting and training center - KEY, 2020)
Constant world population growth imposes the need for the production of
more food, and as a consequence, has an increase in the organic-rich wastes.
These agro-industrial wastes represent problem from the environmental ...
Uticaj grešaka u zavarenim spojevima cevnih lukova na sigurnost rada cevovoda.
(Централни институт за конзервацију, 2020)
Imajući u vidu da greške u zavarenim spojevima ugrožavaju nosivost i sigurnost rada
cevovoda, ispitan je uticaj unutrašnjeg pritiska i momenta savijanja na cevi i cevne
lukove sa inicijalnim oštećenjima. Razmatrane su ...
Optimization of methanol synthesis under forced dynamic operation
(Max Planck Institute, 2020)
Methanol is an essential primary chemical in the chemical industry. Further, there is a growing interest in using methanol also for chemical energy storage. Excess electrical wind or solar energy can be converted to hydrogen ...
Cerium-cysteine complex inhibitor for aluminium alloy AA7075-T6
(Belgrade : Military Technical Institute, 2020)
Aluminium AA7075 alloy with its low density and good mechanical properties, widely responds to the requirements of aerospace, navy, and defense industries. However, corrosion is the most common problem that affects the ...
