“…Based on the tests and the efficiency of the sieving process, the 90 μm fraction was chosen for the preparation of composite samples. The obtained cenospheres were subjected to a two-step chemical modification according to a process previously developed for alumina and zirconia [37,43].…”

“…The importance of this research is that it shows the applicability of CSs in medical applications, but not limited to only that. Composites of this type are suitable for acoustic applications, energy storage, and structural applications [37][38][39]. The manner of their surface modification is also important as it helps to avoid phase separation [40].…”

The main aim of this research was the preparation of a polymer–ceramic composite with PA-12 as the polymer matrix and modified aluminosilicate cenospheres (CSs) as the ceramic filler. The CSs were subjected to an early purification and cleaning process, which was also taken as a second objective. The CSs were surface modified by a two-step process: (1) etching in Piranha solution and (2) silanization in 3-aminopropyltriethoxysilane. The composite was made for 3D printing by FDM. Raw and modified CSs and a composite with PA-12 were subjected to the following tests: surface development including pores (BET), real density (HP), chemical composition and morphology (SEM/EDS, FTIR), grain analysis (PSD), phase composition (XRD), hardness (HV), and static tensile tests. The composites were subjected to soaking under simulated body fluid (SBF) conditions in artificial saliva for 14, 21, and 29 days. Compared to pure PA-12, PA-12_CS had generally better mechanical properties and was more resistant to SBF at elevated temperatures and soaking times. These results showed this material has potential for use in biomedical applications. These results also showed the necessity of developing a kinetic aging model for aging in different liquids to verify the true value of this material.

“…The reinforcement corrosion was also stopped with the help of this crack healing behavior. [21,22] The crystalline admixture has the potential to improve the durability of the concrete as well as to reduce the permeability when the structure is exposed to the environment which leads to the corrosion in the concrete structure. Concrete's compressive strength, self-healing capacity, and durability were evaluated for various cement grades.…”

The most extensively utilized material in construction is concrete, decreasing life of structure pointing toward loses in structural health. The crack is the major problem faced in the concrete construction. This causes the corrosion in the steel reinforcement. The structure gets deteriorated with the developing cracks; therefore need the proper attention toward this problem. The present work consists of the different self‐healing techniques used by the researchers to inhibit the crack and prevent further deterioration in the structure. The self‐healing mechanism proves advantageous in use of natural fibers to inhibit the corrosion process, to increase compressive strength, and to decrease water absorption is present in this study. The maximum strength increased and the width of crack get healed with the help of these techniques is also mentioned in the study.

“…Currently, efforts are being made to use cenospheres in value-added products, such as to reduce weight and increase strength in resins, concrete, plastics, paints, coatings, and ceramics [ 304 ]. Owing to the low density, high strength, astonishing thermal and electric capacity, excellent dispersibility and thermal insulation, high filling ability, and low coziness and viscosity of cenospheres, they have been used as fillers in various polymers, such as polypropylene, polyethylene, polyamides, and vinyl esters [ 299 , 303 , 305 ]. Basically, improvements in the thermal properties of cenosphere-containing composites are widely reported, which confirms the vitreous nature of cenospheres in terms of their high thermal stability and melting range (1350–1450 °C) [ 306 , 307 ].…”

This review provides an intensive overview of flame retardant coating systems. The occurrence of flame due to thermal degradation of the polymer substrate as a result of overheating is one of the major concerns. Hence, coating is the best solution to this problem as it prevents the substrate from igniting the flame. In this review, the descriptions of several classifications of coating and their relation to thermal degradation and flammability were discussed. The details of flame retardants and flame retardant coatings in terms of principles, types, mechanisms, and properties were explained as well. This overview imparted the importance of intumescent flame retardant coatings in preventing the spread of flame via the formation of a multicellular charred layer. Thus, the intended intumescence can reduce the risk of flame from inherently flammable materials used to maintain a high standard of living.
