“…The XRD pattern of the nanosilica was shown in Figure 3. It can be observed from Figure 3 that the only one peak at 2θ ≈ 22 o confirmed the purity and amorphous structure of nanosilica generated from acid treated RH powder [4,14,16].…”

“…Athinarayanan et al also reported the same size of nanosilica harvested by incineration of RH powder at 700 o C for 2 h, while incineration at lower temperature particularly at 500 and 600 o C generated nanosilica with larger size [4]. From the results in Table 1, it indicated clearly that the treatment of 60 ppm of nanosilica was found to be the best for the growth enhancement of chili plant, particularly the fresh weight of shoot and root increased to 17.5 % and 30.4 %, and the dry weight of shoot and root increased to ~90 % and 44.7 %, respectively compared to that of the control (spraying with water).…”

“…By silica content of about 10 % in RH [10], then the silica quantity from RH resource will be nearly 1 million ton/year. Therefore, RH is an abundant agro-waste resource that can be used to harvest amorphous silica from RH ash (RHA) by burning or combustion techniques [3, 11 -13] and nanosilica by incineration of acid treated RH [4,14,15] or treatment of RHA by sol-gel method [16,17]. So that it is also minimized the related environmental issues associated with the current applications and disposables of RH [14].…”

Nanomaterials hold great promise of improved plant disease resistance, controlled release of agro-chemicals, enhanced plant growth, etc. In this study, the effect of nanosilica (10 -30 nm) prepared from rice husk on the growth promotion of chili plant in green house was carried out. The experiment of nanosilica treatment by foliar spraying was arranged in a factorial design with 3 replications at various nanosilica concentrations of 0, 40, 60 and 100 ppm. Plant growth characteristics and chlorophyll content were assessed. Results showed that the fresh weight, dry weight, and chlorophyll content increased with the treatment of nanosilica. The optimal concentration of nanosilica was found to be of 60 ppm. Thus, treatment of nanosilica was beneficial in enhancing the growth of the chili plants.

The use of environment‐benign and earth‐abundant silicon (Si) and carbon (C) is the quest to meet the ever‐increasing Li‐ion battery (LIB) market. Unlike the traditional way of either extracting C or Si, here, we report a molten salt electrolysis approach to controllably extract both C and Si (e. g., C−SiC or C−Si composites) from rice husks (RHs). The RHs are the natural transporter that captures carbon dioxide (CO2) from the air and silicic acid (H4SiO4) from the soil, thus supplying abundant, sustainable, and hierarchically porous C−SiO2 composite feedstocks. In molten CaCl2, carbonized RHs (C−RHs) can be electrochemically reduced to the C−SiC composite that delivers a gravimetrical capacity of over 1000 mA h g−1 at 1000 mA g−1 after 400 cycles. In molten NaCl−KCl−MgCl2, the C−RHs can be electrochemically reduced to C−Si composite that delivers a gravimetrical capacity of 926 mA h g−1 at 500 mA g−1 after 100 cycles. The electrolytic products can be altered by the component of molten salt as well as by adjusting the applied cell voltage. Overall, we employ the photosynthesis of plants to harvest Si and C from nature and, subsequently, the molten salt electrolysis approach to preparing C−SiC and C−Si composites for low‐cost and sustainable LIB anodes.
