Inorganically modified particles FeAl-LDH"SiO2 as reinforcement in poly (methyl) methacrylate matrix composite
(Royal Society Open Science, 2021)
Silica particles were obtained from rice husk to which layered double hydroxide particles were deposited (weight ratio 1 : 1). Fe2+-Al3+ layered double hydroxides (FeAl-LDH) were synthesized by co-precipitation with ratios ...
An Experimental Study of Mechanical Properties and Heat Transfer of Acrylic Composites with Structural and Surface Modified Al2O3 Particles
(International Institute for the Science of Sintering (IISS), 2020)
Thermal properties of acrylate-based composite combined with alumina-based particles were investigated. The composites were made of poly (methyl methacrylate) (PMMA) modified with dimethyl itaconate (DMI) as a matrix. Neat ...
The influence of thermodynamic parameters on alkaline activator of geopolymers and structure of geopolymers
(Macedonian Journal of Chemistry and Chemical Engineering, 2021)
Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 °C for the process of geopolymerization. ...
