Abnormalni rast zrna u toku medjužarenja u Al-Mg legurama / Abnormal grain growth during intermediate annealing of Al-Mg alloys
(Beograd : Srpsko hemijsko društvo = Serbian Chemical Society, 2022)
U završnoj fazi prerade Al-Mg legura, pojava abnormalnih zrna (AGG) u strukturi je
nepoželjna, jer dovodi do pogoršanja mehaničkih osobina. Medjutim, postoji veliki interes
za proučavanjem uticaja AGG, koja nastaju u ...
Investigation of antioxidant activity of 6-hydroxy-6-methyl-2-pyridones / Ispitivanje antioksidativne aktivnosti azo boja na bazi 6--hidroksi-4-metil-2-piridona
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Društvo za procesnu tehniku, 2022)
Considering a significant antioxidant activity of 6-hydroxy-6-methyl-2-pyridones, in this paper four series of arylazo pyridone dyes were subjected to antioxidant ABTS assay. Firstly, preliminary tests were conducted at ...
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 ...
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 ...
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 ...
Electrochemical composite bioceramic coatings based on hydroxyapatite, chitosan and polyvinyl alcohol loaded with gentamicin
(Institute of Technical Sciences of SASA, 2021)
Composite bioceramic coatings have been attracting increasing attention of the scientific
public in recent decades due to the good potential of their use for medical purposes. The
main goal of this scientific research ...
Optimization of Sweet Cherry Extraction: Evaluation of Total Phenol Content, Protein Content, and Antioxidant Activity of Extracts
(University of Novi Sad, Faculty of Technology Novi Sad, 2022)
Cherry fruits are known for their wide range of nutritive and bioactive compounds, including
fibers, vitamins, and phytonutrients. Sweet cherry consumption has been associated with
several health benefits against human ...
BIOMIMETIC BIOREACTORS IN CHARACTERIZATION OF NOVEL BIOMATERIALS
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2022)
Development of novel biomaterials for potential biomedical applications requires comprehensive preclinical studies. Traditional methods for biomaterial evaluation are based on in vitro testing routinely performed in monolayer ...
Eco-friendly technology for gel-coat and fireproofing material production using bio-renewable and waste materials
(OOO «Centr «AЮMЭLЬ», 2020)
Innovative technology has been developed for the production of gelcoat and materials of reduced flammability based on unsaturated polyester resins. These materials were synthesized from raw materials obtained from waste ...
Thermovision monitoring of concrete heat of hydration / Termovizijski monitoring toplote vlaženja betona
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2020)
Usled hemijske reakcije Portland cementa, koja se uvek javlja u betonu prilikom očvršćavanja, izvesna količina toplote se razvija. Ova toplota mora biti kvantifikovana, obzirom da ona može oštetiti beton ili pomoći mu, ...
