One of the consequences of industrial food production activities is the generation of high
volumes of waste, whose disposal can be problematic, since it occupies large spaces, and …

Rice husk are generated from the rice cultivation. Silica is the major inorganic constituent of
the rice husk, and by carrying out an acid chemical treatment followed by the process of …

An overview of different aspects related to Materials and Nanomaterials Chemistry is
presented and discussed. The insertion of this field in Brazil is evaluated on the basis of the …

Nanoparticles of SiO 2 were synthesized via sol-gel route using sugarcane bagasse ash as
a silica source. The influence of the synthesis operational conditions, as well as, the use of …

In this study, biogenic SiO2 of high purity and high surface area obtained from rice husk was
used for prepare a nanostructured SnO2/SiO2composite. The predominantly amorphous …

Closed pore glass foams with dimensions of 60mm× 20 mm× 20 mm were produced using
agro-industrial residues. Samples containing sodo-calcic glass powder (78% wt) and rice …

This study compared properties of silica (SiO2) from rice husk (RH) and rice husk ash (RHA)
extracted by acid-and heat-treatment. The SiO2 from RH was in amorphous phase with …

Concrete is one of the most widely consumed materials in the world. It is composed mainly
of natural aggregates-70–80% of its volume. Extraction of natural aggregates for concrete …

This study investigates the technological, thermal, mechanical, and technological properties
of glass foams produced with soda-lime glass residues and rice husk ash sintered at 850 …

This paper presents a study on the production of silica gel in hydrothermal process using
residual rice husk ash. Measurements of the chemical composition, X-ray diffraction, infrared …
