“…The tensile and tear strengths of the test pieces with higher RHA were not in tandem/agreement with the increased hardness value. The concentration of 30 phr for the silica+RHA had better mechanical properties compared to the silica filler alone [57]. Fused, crystallized silica and RHA's properties as fillers were established.…”

Asian countries rely massively on rice to feed and sustain its massive population. For long the staple food has provided nourishment to the masses and the classes. Rice is grown in large quantities in Asian countries. A by-product of its cultivation is its husk. The husk of the rice grain is mainly utilized as a fuel for the boilers in the rice mills. The uncontrolled burnt rice husk referred to as rice husk ash consists majorly of silica. silica is used in a wide variety of commercial and industrial applications. Use of rice husk ash in various products serves to reduce the pollution caused by its pileup in localities especially close to the rice mills. More sustainable and an affordable source of Si would benefit the society rather than disposing rice husk ash in the fields and landfills. This brief review provides insights into the synthesis, applications, and properties of rice husk ash incorporated products either directly in the as received conditions or under modified conditions.

Rice-husk ash (RHA) is prepared from a by-product of rice production. Its main component is silic dioxide. Thanks a zeolite-like structure, it could be used as an adsorbent. In this study, RHA was used to remove some antibiotic and anti-inflammatory drugs in aqueous medium such as Cefuroxim, Dexamethasone, Methylprednisolone, Prednisolon. These drugs are recommended to use at home for Covid-19 patients. The RHA has a specific surface area of 179.797 m2/g), the pore size of 63.547 m2/g, the average particle size of 3.8 mm. The zeta potential of RHA in distilled water of -42.5 V, the point of zero charge of 6.7. The main composition of elements in RHA is Si, O, C. Among investigated samples, the Cefuroxim adsorption efficiency of RHA is the best, with a adsorption capacity reached 1.43 mg.g-1 and adsorption efficiency reached 86.00 % at the optimum adsorption condition of pH solution of 7, adsorption time of 150 min, RHA weight of 0.3 g and the initial drug concentration of 5.0 mg.L-1.

“…As an important nano-filler, silica is also widely used in rubber reinforcement materials. The vulcanisation kinetic behavior [23], vulcanisation characteristics [24, 25] and mechanical properties [26-29] of silica-filled rubber mixtures have attracted the attention and research of rubber science and technology workers. The researchers mainly explored the change mechanism of vulcanisation reaction rate of silica rubber composite from the perspective of vulcanisation reaction kinetics, and studied the effects of vulcanisation process, silica content, silica modification and mixing with other fillers on the microstructure and mechanical properties of rubber.…”

The thermal and mechanical properties of rubber used in tires were measured experimentally. The effect of temperature on the thermal properties and the effect of vulcanisation time on the mechanical properties are analyzed. The specific heat capacity and thermal conductivity both increase with increasing temperature, and the specific heat capacity and thermal conductivity are approximated as linear functions of temperature. The tensile strength, elongation at break and abrasion properties of vulcanizate are significantly affected by the vulcanisation time. As the vulcanisation time increases, the tensile strength first increases and then decreases, and the elongation at break changes with the vulcanisation time on the contrary. The wear volume of tread rubber first decreases and then increases with the increase of vulcanisation time. At the positive vulcanisation time, the tensile strength of the vulcanizate reached the maximum value, while the elongation at break and wear volume reached the minimum value.
