The ZnO/activated carbon nanocomposites are a potential adsorbent for treating polluted water. The effect of the mass ratio of molten ZnCl2 and rice husks, pyrolysis temperature on the characteristics and methylene blue (MB) adsorption capacity were charaterized. The adsorption isotherm and kinetics of the organic dye MB on the prepared ZnO/activated carbon were also thoroughly investigated.

An experimental study on compressive strength of mortar mixes containing different amounts of rice husk ash (5, 10, 20%) has been investigated. The impact of different elevated temperatures (150, 300, 450, 750o C) on mortar strength is also examined. The experiments found that RHA can be used in its untreated form up to 10% as cementitious replacement without detriment of mortar compressive strength. Furthermore, the addition of RHA improves the resistance of mortars at high temperatures excepting to the ones with replacement ratio of 20%.

The impact of different rice husk ash contents (5, 10, 20%) on mortar strength is examined at different elevated temperatures (150, 300, 450, 750oC). Based on a 45 experimental result data set, three machine learning algorithms including the Artificial Neural Network (ANN), the Least Squares Support Vector Regression (LS-SVR) and the Multivariate Adaptive Regression Splines (MARS) have been used to model the functional relationship between the mixture components and the compressive strength.

Clean water for drinking and cooking has been a serious issue in rural areas of Vietnam, which is mainly due to high-cost treatment of the available water sources in such areas. In order to reduce the treatment cost, iron impregnated ceramic granules (IICGs) was synthesized using a mixture of locally available montmorillonite and crushed rice husk (with the rice husk size < 0.2 mm, IICGs size 0.2 mm – 0.45 mm).

Rice husk (RH), an inexpensive waste material, was used to produce nanosilica that was then applied to fabricate composite with natural rubber. The optimization of process parameters on the weight of nanosilica using the Taguchi method was performed. Experimental specimens were then made to confirm optimum values for each process parameter.

The thermal behaviour of bio-fillers and biofiller/polyolefin composites were studied with thermogravimetric analysis. The thermal analysis of the fillers showed rice husk has thermal resistance comparing to sawdust. In the air atmosphere, the main peak of rice husk degradation shifted to lower temperature values compared to that in nitrogen atmosphere.
