Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Elsevier Ltd, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
Sinteza, karakterizacija i ispitivanje antioksidativne aktivnosti estarskih i amidnih derivata 2,6-dimetil-4-supstituisane-1,4-dihidropiridin-3,5-dikarboksilne kiseline
(University of East Sarajevo, Faculty of Technology, 2018)
Six ester and amide derivates of 2,6-dimethyl-4-(substituted)-1,4-dihydropyridine-3,5-dicarboxylic acid have been synthesized in this paper, including: diethyl 2,6-dimethyl-4-phenyl-1,4-dihydropyridine-3,5-dicarboxylate, ...
Modelling, simulation and optimisation of pulse-reverse regime of copper, silver and gold electrodeposition
(Carl Hanser Verlag, 2018)
Pulse-reverse power modes are used in galvanotechniques in order to obtain coatings with better characteristics in terms of gloss, adhesion, tracking sharp edges and uniform distribution of deposits on complex shape objects, ...
Novel nano-composite hydrogels with honey effective against multi-resistant clinical strains of Acinetobacter baumannii and Pseudomonas aeruginosa
(Springer, New York, 2019)
Novel alginate hydrogels with silver nanoparticles (AgNPs) and honey components were produced with the aim to target multidrug-resistant bacterial strains causing nosocomial wound infections. AgNP synthesis was optimized ...
Enhanced absorption of TiO2 nanotubes by N-doping and CdS quantum dots sensitization: insight into the structure
(Royal Soc Chemistry, Cambridge, 2018)
Anodization of titanium film sputtered on fluorine doped tin oxide (FTO) glass was performed to obtain highly ordered approximate to 2 m long and approximate to 60 nm wide TiO2 nanotubes. The titania films were annealed ...
Optimization of Bioreactor Cultures of Glioblastoma Cells Immobilized in Alginate Microfibers
(Institute of Technical Sciences of SASA, 2021)
Glioblastoma is the most common and aggressive malignant brain tumor in adults. Existing
treatment choices that include surgery, radiation and chemotherapy are not successful in
long-term survival, while development of ...
Modifikovana nanoceluloza kao nosač za imobilizaciju lipaze iz Candida rugosa / Modified nanocellulose as a support for adsorption of lipase from Candida rugosa
(Beograd : Srpsko hemijsko društvo, 2016)
Sa ubrzanim razvojem nanotehnologije, celuloza kao najrasprostranjeniji i najvažniji prirodni polimer na zemiji privlači sve veću pažnju u formi nanoceluloze. Zbog svoje biodegradabilnosti, biokompatibilnosti i velike ...
Doping of TiO2 nanotubes with nitrogen by annealing in ammonia for visible light activation: Influence of pre- and post-annealing in air
(Elsevier Science Sa, Lausanne, 2019)
The similar to 60 nm wide and similar to 2 mu m long TiO2 nanotubes were obtained by anodization of Ti films sputtered on F-doped tin oxide glass. For N-doping the samples were annealed in ammonia atmosphere. The effect ...
Veštački zaslađivači u podzemnoj vodi kao indikatori komunalnog zagađenja / Artificial sweeteners in groundwater as indicators of municipal pollution
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2021)
Velika primena veštačkih zaslađivača kao aditiva u hrani, piću, lekovima i sredstvima za oralnu higijenu je dovela do akumuliranja ovih supstanci u akvatičnim ekosistemima širom sveta. Pošto je većina njih metabolički ...
The influence of alumina particle modification on the adhesion of the polyacrylate matrix composite films and the metal substrate
(Taylor & Francis Ltd, Abingdon, 2019)
Adhesion behavior between the composite films, consisting of UV cured Bis-GMA (Bisphenol A glycidylmethacrylate)/TEGDMA (triethylene glycol dimethacrylate) as a matrix and the ferrous oxide doped alumina particles, Al2O3 ...
