“…As degumming begins, the peak intensity increases gradually from CF-0.5 to CF-10. The increase in peak intensity and height conveys the increase in the crystallinity of the fibers upon degumming . However, the peak intensity drops slightly for CF-12, imparting that over-exposure to NaOH solution may have started to affect the core structure of the silks.…”

Silkworm silk proteins are of great importance in several fields of science owing to their outstanding properties. India generates waste silk fibers, also known as waste filature silk, in abundance. Utilizing waste filature silk as reinforcement in biopolymers enhances its physiochemical properties. However, the hydrophilic sericin layer on the surface of the fibers makes it very difficult to have proper fiber–matrix adhesion. Thus, degumming the fiber surface allows better control of the fiber properties. The present study uses filature silk (Bombyx mori) as fiber reinforcement to prepare wheat gluten-based natural composites for low-strength green applications. The fibers were degummed in sodium hydroxide (NaOH) solution from a 0 to 12 h duration, and composites were prepared from them. The analysis exhibited optimized fiber treatment duration and its effect on the composite properties. The traces of the sericin layer were found before 6 h of fiber treatment, which interrupted homogeneous fiber–matrix adhesion in the composite. The X-ray diffraction study showed enhanced crystallinity of the degummed fibers. The FTIR study of the prepared composites with degummed fibers showed that shifted peaks toward lower wavenumbers supported better bonding among the constituents. Similarly, the tensile and impact strength of the composite made of 6 h of degummed fibers showed better mechanical properties than others. The same can be validated with the SEM analysis and TGA as well. This study also showed that prolonged exposure to alkali solution reduces the fiber properties, thus reducing composite properties too. As a green alternative, the prepared composite sheets can potentially be applied in manufacturing seedling trays and one-time nursery pots.

“…Due to the lack of an electrical charge, these surfactants are resistant to water hardness deactivation. Nonionic surfactants offer a wide range of applications in textiles, and they are widely utilized. , The polyoxymethylene alkylphenols and polyoxyethylenates are the most prevalent kinds of nonionic surfactants. Detergents, solubilizers, and emulsifiers can all benefit from nonionic surfactants …”

Iron ore is generally transported using a traditional method that releases significant amounts of dust into the environment. In contrast, the pipeline transportation of slurry is noticeably a sustainable approach for efficiently transporting iron ore by reducing the environmental pollution. The interparticle interaction of the iron ore particles should be mutually repulsive for steady dispersion. Surfactants and polymers adsorb efficiently at the solid/liquid interface due to their amphiphilic character, rendering the surface hydrophilic or hydrophobic to create a stable dispersion. The present review discusses the interaction of surfactants on the stabilization of solid particles for the ease of pipeline transportation using various types of stabilization mechanisms. In addition to the effect of surfactant alone, its combination with some other parameters such as particle size distribution, temperature, solid concentration, etc. has been discussed. The review also describes the detailed classification of iron ore, surfactant, and characteristic properties of surfactants.

[42][43][44][45][46] Natural products with architectural complexity are frequently the motivating factor behind the design of innovative ways for constructing the expected scaffold. [47,48] In principle, designing a pathway for the total synthesis of two or more natural products via a standard intermediate would be more tenacious than designing a synthesis pathway for a single natural product.…”

Gold catalysis is an extremely enthusiastic field of investigation in the catalysis area. The development of alternative, highly inventive, precompetitive techniques based on gold catalysis has paved the way for executing a broad spectrum of chemical transformations from uncomplicated starting materials. The total synthesis of natural products is a complex and more complicated task. An amalgamation of natural product synthesis through goldcatalysis has been a thought-provoking job. The protocol has solved several problems related to the synthesis of numerous complicated natural products. Thus, this review has outlined some of the most notable benchmarks from the last seven years (2015-2021) on gold catalysis and their application in the total synthesis of numerous natural products. The strategy acquired by the authors to accomplish the total synthesis will be elaborately discussed by emphasizing the role of the gold-catalyzed reactions.
