Nanocomposites and a composite based on poly(butylene adipate-co-terephthalate) (PBAT) were synthesized using commercial copper nanoparticles (Cu-NPs), copper/cuprous oxide (Cu|Cu2O-NPs), sulfate (CuSO4), respectively. The Cu|Cu2O-NPs chemical reduction characterized by X-ray diffraction (XRD) transmission electron microscopy (TEM). synthesis of yielded mixture Cu Cu2O, with metal having spherical morphology approximately 40 nm in diameter Cu2O 150 nm. To prepare the nanocomposites (NCs)...
Poly(butylene adipate‐ co ‐terephthalate) (PBAT) was mixed with copper nanoparticles (Cu‐NPs) in concentrations of 1%, 3%, and 5% particle size between 100 nm 200 by the melting method. A morphological, thermal, structural characterization nanocomposites (NCs‐PBAT/Cu) performed to analyze effect Cu‐NPs on polymer chains, as well explain influence their crystallinity, its thermomechanical antibacterial properties. The percentage crystallinity (X c ) increased 6.7% 9.5% amount matrix....
The effect of microencapsulation dihydrogen ammonium phosphate (MAP) in the generation fire-resistant coatings was studied presence tannins extracted from Pinus radiata. MAP encapsulated to avoid interaction with sodium carbonate (Na2CO3), which, upon contact fire, generates unwanted gases. Thus, a fireproof (or intumescent) protective film produced tannins. Microcapsules were polymerized melamine and characterized by Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis...
The development of high-entropy alloys has been hampered by the challenge effectively and verifiably predicting phases using predictive methods for functional design. This study validates remarkable phase prediction capability in complex multicomponent microstructurally two novel FCC + BCC IM systems a analytical method based on valence electron concentration (VEC). results are compared with machine learning, CALPHAD, experimental data. key findings highlight high accuracy its strong...
ABSTRACT Through the development of nanotechnology it has been widely studied morphology and size control in nanopowders synthesis. However, most these techniques are successful to synthesize a small scale. In this research, large semi‐industrial scale synthesis method is proposed, named continuous arc discharge controlled atmosphere (DARC‐AC). Using technique, possible directly obtain clean nanostructures (low amount impurities) with more than 90% particles below 100 nm. study, utilizes...
