“…[132] Regarding optical properties, improved compatibility between the biobased matrix and NP additive leads to better dispersion of the additive in the matrix, promoting the formation of transparent materials with high UV blocking capacity. [128,[132][133][134] While lignin can be an effective UV absorber, the color of this material (brown-black color) can be undesirable or even detrimental to device efficiency because it reduces transparency in the visible range. This coloration depends on the number of unsaturated bonds in the lignin [135] and can be manipulated by different methodologies of extraction or modification, e.g., to obtain colorless lignin.…”

This review addresses the reconstruction of structural plant components (cellulose, lignin, and hemicelluloses) into materials displaying advanced optical properties. The strategies to isolate the main building blocks are discussed, and the effects of fibrillation, fibril alignment, densification, self‐assembly, surface‐patterning, and compositing are presented considering their role in engineering optical performance. Then, key elements that enable lignocellulosic to be translated into materials that present optical functionality, such as transparency, haze, reflectance, UV‐blocking, luminescence, and structural colors, are described. Mapping the optical landscape that is accessible from lignocellulosics is shown as an essential step toward their utilization in smart devices. Advanced materials built from sustainable resources, including those obtained from industrial or agricultural side streams, demonstrate enormous promise in optoelectronics due to their potentially lower cost, while meeting or even exceeding current demands in performance. The requirements are summarized for the production and application of plant‐based optically functional materials in different smart material applications and the review is concluded with a perspective about this active field of knowledge.

“…The work to produce ChNC from shrimp shells by maleic acid hydrolysis was worked by Yang's research group, they used hydrolysis temperature of 110 o C, 3 hours hydrolysis time, and 80% maleic (Yang et al, 2020). The result was very good and this nanohybrid particle can be potentially used in the wastewater field.…”

Cellulose and chitin are two of the most abundant biopolymer on earth, have been attracted a lot of interest from many researchers, especially related to their nanoparticles form. Recently the method to extract them into nanoscale materials mostly by mineral or liquid acid hydrolysis, such as sulfuric and hydrochloric acid. Despite their high yield production, many disadvantages are produced by their use as a hydrolysis catalyst, such as low thermal stability and are difficult to be functionalized due to the presence of sulfate groups, tendency to be aggregated due to the bare surface charge density, the potential excessive degradation of cellulose; and large amounts of effluent will be produced due to the neutralization stage and corrosion hazards to the equipment and environment. To overcome the drawback of those acids, solid acid can be used to produce cellulose (CNC) and chitin nanocrystals (ChNC). Their ability to recrystallize and recycle makes them more environmentally friendly, furthermore, most of the acid can do esterification on the surface of cellulose and chitin. The purpose of this paper is to provide a critical review of recent progress related to solid acid hydrolysis since they have interesting characterization even some of their attribute is better than the conventional method.

“…The high surface energy of nanoparticles is the reason why they aggregate and precipitate out of the liquid phase. In other to prevent this effect, various types of stabilizers have been used, including biomacromolecules like, e. g. lignosulfonates, which can play a double role –as reduction agents and stabilizers at the same time [14–16].…”

A method of producing nanosilver by using lignosulfonic acid derivative and a new method of the obtained AgNPs‐LS electrode material for developing a chemically modified GCE/AgNPs‐LS/Hg electrode is presented. The data demonstrate that the modified electrode shows enhanced performance in determining Tl+ ions in comparison to unmodified electrode GCE. The stripping anodic peak current of thallium characterized in linearity over its concentration range from 1.22 ⋅ 10−8 to 1.15 ⋅ 10−7 mol dm−3, with detection limit 4.6 ⋅ 10−9 mol dm−3. It is assumed that the novel AgNPs‐LS/Hg2+ complex is suitable for preparing functionalized nanostructured material and can be used as an electrochemical sensing platform for heavy metals.
