Effect of mechanical activation on carbothermal synthesis and densification of ZrC
(Elsevier BV, 2023)
Zirconium carbide ceramics were prepared by carbothermal reduction of ZrO2 and C that were mixed by high-energy ball milling. Powders were milled for times from 0 to 120 min in air. As milling time increased, the surface ...
Nanomechanical properties of PVDF–ZnO polymer nanocomposite
(Elsevier BV, 2023)
Poly(vinylidenefluoride)–ZnO (PVDF–ZnO) nanocomposites with mechanically activated ZnO nanoparticle fillers were investigated using thermal and mechanical analysis and AFM and PFM. Differential scanning calorimetry (DSC) ...
A database of simultaneously recorded ECG signals with and without EMG noise
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Goal: Noise on recorded electrocardiographic (ECG) signals may affect their clinical interpretation. Electromyographic (EMG) noise spectrally coincides with the QRS complex, which makes its removal particularly challenging. ...
Logarithmic time encoding and decoding of integer error control codes
(Wiley, 2023)
One of the most important characteristics of all error control codes (ECCs) is the complexity of the encoding/decoding algorithms. Today, there are many ECCs that can correct multiple bit errors, but at the price of high ...
Photocatalytic degradation of bisphenol A in aqueous solution using TiO2/clinoptilolite hybrid photocatalyst
(Environmental Science and Pollution Research, 2023)
Photocatalytic degradation of bisphenol A (BPA) was investigated using commercial TiO2 P25 nanoparticles supported on natural zeolite clinoptilolite (Cli). Employing ultrasound assisted solid-state dispersion method hybrid ...
Polypyrrole on graphite: An exemplary model system for comprehensive electrochemical analysis of energy storage materials
(Elsevier BV, 2023)
Electrochemical Energy Storage (EES) technologies are playing a significant role in the aspirations to decrease the usage of fossil fuels and move toward an environmentally conscious society. Due to the importance of EES ...
Synthesis, densification, and cation inversion in high entropy (Co,Cu,Mg,Ni,Zn)Al2O4 spinel
(Informa UK Limited, 2023)
The synthesis, densification behavior, and crystallographic site occupancy were investigated for four different spinel-based ceramics, including a high-entropy spinel (Co0.2Cu0.2Mg0.2Ni0.2 Zn0.2)Al2O4. Each composition was ...
Citotoksični i genotoksični potencijal kompozita na bazi nanočestica resveratrola i selena, i njegova sposobnost indukcije superoksidnih anjona / Cytotoxic and genotoxic potential of composite based on resveratrol and selenium nanoparticles, and its potential for superoxide anion induction
(Beograd : Udruženje toksikologa Srbije, 2023)
Kontinuirano interesovanje za nanočestice različitih materijala i njihove kompozite stvorilo je brojna pitanja u vezi njihove potencijalne toksičnosti. Polifenol resveratrol i jedinjenja sa selenom su među agensima čijoj ...
Procena antioksidativnog, citotoksičnog i genotoksičnog efekta etarskog ulja cimeta i njegove emulzije / Evaluation of antioxidative, cytotoxic and genotoxic effect of cinnamon essential oil and its emulsion
(Beograd : Udruženje toksikologa Srbije, 2023)
Cimet je jedna od najpoznatijih aromatičnih biljaka, koje je najčešće korišćena kao začin. Prepoznat je kao potencijalni terapeutik u narodnoj medicini, zbog čega se dugo koristi za lečenje različitih infekcija. Etarska ...
Frangula alnus ekstrakt i emodin kao potencijalni antikancerski agensi / Frangula alnus extract and emodin as potential anticancer agents
(Beograd : Udruženje toksikologa Srbije, 2023)
Hepatocelularni i kolorektalni karcinom se sve ćešće javlja i ima visoku stopu smrtnosti. Postojanje aktivnih mehanizama hemorezistencije otežava korisnost hemoterapije. Upravo je pojava hemorezistencije podstakla opsežna ...
