Biosynthesis and Characterization of Silica Nanoparticles from Rice (Oryza sativa L.) Husk

Silica Nanoparticles from Coir Pith Synthesized by Acidic Sol-Gel Method Improve Germination Economics

“…The bandgap vibration of electronic transition was found at the broad value of 305 nm for soluble silica suspension. In line with this, Patil et al [40] concluded that the UV-visible spectrum of n Si displayed the maximum absorption band edge of 310 nm. The optical property of silica nanomaterials is related to the occurrence of various defects caused by the partial formation of a Si-O-Si tetrahedral network at the surface, namely silicon and oxygen vacancies.…”

Preparation of green film with improved physicochemical properties and enhanced antimicrobial activity using ingredients from cassava peel, bamboo leaf and rosemary leaf

“…The average particle size of the SNP from bamboo leaf (BL) was mainly 7.48 nm (78.6%) ( Figure 3 a) and the size of SNP from rice husk was mainly about 2759 ± 1273 nm (73.7%) ( Figure 3 b). Previous researchers reported SNPs with average size of 93.14 nm ( Patil et al., 2018 ) and 60 nm ( Sharifnasab and Alamooti, 2017 ) from rice husk. The size of 78.6% of the SNPs extracted from BL is significantly smaller as compared to the SNPs from RH.…”

“…SNPs were extracted from rice husk and bamboo leaf using a method adapted from previous studies ( Patil et al., 2018 ) ( Figure 2 ). The collected bamboo leaf and rice husk were first washed with tap water and sun dried for 4 days followed by oven drying for 3 h at 100 °C.…”

“…On the other hand, the films from modified blend (with and without REO) and the film from unmodified blend were analyzed by taking the required size of the films. All samples were scanned in the range of 4000–500 cm −1 ( Patil et al., 2018 ).…”

“…2.2.4. Extraction 228 of SNPs from rice husk, and bamboo leaf SNPs were extracted from rice husk and bamboo leaf using a method adapted from previous studies (Patil et al, 2018) (Figure 2). The collected bamboo leaf and rice husk were first washed with tap water and sun dried for 4 days followed by oven drying for 3 h at 100 C. The dried leaf and rice husk were reduced in size and 560 g of each was taken separately and combusted at 600 C for 3 h in the Muffle furnace.…”
