“…Specifically, according to Figure S2 (Supplementary Materials) , light transmittance of 0.1 wt% TEMPO-CNF is almost 100% across the wavelength of 400–1100 nm. This is similar to that reported by Hu et al [ 29 ]. At the same gel concentration (0.1 wt%), the light transmittance at 600 nm of TEMPO-CNF derived from corn stover (this study) is similar to that prepared from softwood bleached kraft pulp or microcrystalline cellulose (both ~99% light transmittance) [ 30 ], but slightly higher than that extracted from jute bast fibers (~90%) [ 31 ].…”

Agricultural byproducts such as corn stover are widely available sources for preparation of nanocellulose, which is an emerging green chemical with versatile applications. In this study, corn stover-derived nanocellulose was prepared via bleaching, alkaline treatment, 2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO) oxidation, and ultrasonication. The as-prepared TEMPO-oxidized cellulose nanofibril (TEMPO-CNF) was characterized by transmission electron microscopy, UV-Vis spectrophotometry, rheometry, and zeta potential measurement. Droplet size, phase behavior, and thermodynamic stability of TEMPO-CNF stabilized oil-in-water emulsions were investigated. Results show that TEMPO-CNF with a width of 4 nm, length of 353 nm, and surface charge of 1.48 mmol/g COO- can be prepared from corn stover. In addition, TEMPO-CNF can be used as an emulsion stabilizer for lemongrass essential oil loaded oil-in-water emulsion. This study is among the first to report that TEMPO-CNF improved the freeze-thaw stability of oil-in-water emulsions stabilized by small molecular weight surfactants (e.g., Tween 80).

Natural resources are practically infinitely abundant in nature, which stimulates scientists to create new materials with inventive uses and minimal environmental impact. Due to the various benefits of natural carbon dots (NCDs) from them has received a lot of attention recently. Natural products-derived carbon dots have recently emerged as a highly promising class of nanomaterials, showcasing exceptional properties and eco-friendly nature, which make them appealing for diverse applications in various fields such as biomedical, environmental sensing and monitoring, energy storage and conversion, optoelectronics and photonics, agriculture, quantum computing, nanomedicine and cancer therapy. Characterization techniques such as Photoinduced electron transfer, Aggregation-Induced-Emission (AIE), Absorbance, Fluorescence in UV–Vis and NIR Regions play crucial roles in understanding the structural and optical properties of Carbon dots (CDs). The exceptional photoluminescence properties exhibited by CDs derived from natural products have paved the way for applications in tissue engineering, cancer treatment, bioimaging, sensing, drug delivery, photocatalysis, and promising remarkable advancements in these fields. In this review, we summarized the various synthesis methods, physical and optical properties, applications, challenges, future prospects of natural products-derived carbon dots etc. In this expanding sector, the difficulties and prospects for NCD-based materials research will also be explored.

“…5 Manganese (Mn) is another essential trace element and plays an important role in the proper development of brain and various enzymatic metabolic processes. 6 An elevated Mn content in the human body can have an adverse effect on the nervous system and induce several neurotransmitter systems, thus leading to violent acts, hallucinations, depression, and Parkinson's-like syndrome. 7 Thus, it is imperative to develop a sensitive and selective approach to monitor Cu 2+ , Mn 2+ , and Co 2+ in terms of human health and environmental protection.…”
