Nanotechnology has shown interest in the utilization of agricultural byproducts as a source for nanostructured materials. Due to their distinctive chemical, thermal, mechanical, morphological, optical, and electrical properties, cellulose nanocrystals (cNcs) have often found utility in a variety of fields. Using sulphuric acid with a 64% weight-to-weight ratio, we managed to extract cNcs chemically from rice husks for the study and examined the effects of varying the hydrolysis period and synthesized composites on optical and thermal characteristics. The usual procedure for preparation was followed, but set the hydrolysis time for 40, 60 and 90 minutes, and also varied temperature at 40˚c, 45˚c and 50˚c. Tonic water and silver nanoparticles were used to synthesize the composites at different ratios. The samples were characterized using UV-Vis spectroscopy, Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSc) techniques. From the results of this study, maximum absorption is observed to shift to shorter wavelengths with an increase in temperature, and the peak absorbance (maximum wavelength) generally increased with hydrolysis time at all three temperatures. The FTIR spectrum of cellulose nanocrystals (cNcs), AgNPs and their composites exhibited distinctive absorption bands indicative of their molecular structure and chemical composition. From the TGA findings, the two composites had a relatively low thermal stability, hence restricting their application to a fixed temperature and below. Additionally, this property makes the composite easily formable into intricate designs, which is ideal for use in optical components and sensors. The low melting point also facilitates recycling and reprocessing, enhancing sustainability by enabling the reuse of the material in various applications. Moreover, the composite’s sensitivity to temperature can be useful in temperature-sensing applications, where change

Metagenomics is the study of microbial communities sampled directly from their natural environment, without prior culturing. By enabling an analysis of populations including many （so-far） unculturable and often unknown microbes, metagenomics is revolutionizing the field of microbiology, and has excited researchers in many disciplines that could benefit from the study of environmental microbes, including those in ecology, environmental sciences, and biomedicine. Specific computational and statistical tools have been developed for metagenomic data analysis and comparison. New studies, however, have revealed various kinds of artifacts present in metagenomics data caused by limitations in the experimental protocols and/or inadequate data analysis procedures, which often lead to incorrect conclusions about a microbial community. Here, we review some of the artifacts, such as overestimation of species diversity and incorrect estimation of gene family frequencies, and discuss emerging computational approaches to address them. We also review potential challenges that metagenomics may encounter with the extensive application of next-generation sequencing （NGS） techniques.
