Mesoporous structure of doped and undoped PEG on Ag/TiO₂ thin film
(IOP Publishing Ltd, 2019-08)
In this reaserch, photocatalyst silver titanium dioxide was doped and modified by Polyethylene Glycol (PEG). The purpose of the present study was to analyse the synthesized Ag/TiO₂ thin film doped and undoped PEG. Ag/TiO₂ ...
Correlation of microstructure and flexural strength of fly ash geopolymer of varying molarities
(IOP Publishing Ltd, 2019-08)
The present work studies and compares the flexural properties of fly ash geopolymer with varying molarity of sodium hydroxide (NaOH). Different molarities of NaOH solution (6M, 8M, 10M, 12M and 14M) are used to prepare the ...
Preparation of heat treated Titanium Dioxide (TiO₂ ) nanoparticles for water purification
(IOP Publishing Ltd, 2018-06)
Photocatalysis using the semiconductor titanium dioxide (TiO₂) has proven to be a successful technology for waste water purification. The photocatalytic treatment is an alternative method for the removal of soluble organic ...
Characteristics of thermoplastic potato starch/bentonite nanocomposite film
(IOP Publishing Ltd, 2018-06)
The aim of this study is to investigate the effect of bentonite towards thermoplastic potato starch nanocomposite films on the mechanical, microstructure and physical properties. The nanocomposite films were prepared using ...
Optimization of processing parameters for graphitization of oil palm trunk waste at lower heating temperature
(IOP Publishing Ltd, 2019-07)
