“…More so, amylose is distinct from other sugars in that it can crystallize independently or in the presence of complexing agents [ 33 , 35 ]. The starch pasting and gel properties of a substance are significantly affected by the level of amylose content [ 36 , 37 ]. On a commercial scale, food and industrial applications could benefit considerably from variations in the amylose content of starch [ 29 ].…”

“…The limitation of physical foaming agents is that some are fragile to provide needed mechanical strength. For instance, dextrin as a forming agent is more chemically stable; they are not better for high-strength products [ 37 ]. However, the mixture of foaming agents could provide both physical and mechanical characteristics, thus making them ideal for applications that demand a well-balanced material.…”

“…Foaming agents from organic and inorganic compounds could be used for chemical foaming. However, for glass materials, chemical foaming agents and their advantages are CaSO 4 (improves foaming ability of glass materials), carbonates, sulfates, and carbon black [ 286 ], while Na 2 HPO 4 (reduces pore nonuniformity of foams) is used as a stabilizer [ 37 ].…”

Valorization of Starch to Biobased Materials: A Review

Many concerns are being expressed about the biodegradability, biocompatibility, and long-term viability of polymer-based substances. This prompted the quest for an alternative source of material that could be utilized for various purposes. Starch is widely used as a thickener, emulsifier, and binder in many food and non-food sectors, but research focuses on increasing its application beyond these areas. Due to its biodegradability, low cost, renewability, and abundance, starch is considered a “green path” raw material for generating porous substances such as aerogels, biofoams, and bioplastics, which have sparked an academic interest. Existing research has focused on strategies for developing biomaterials from organic polymers (e.g., cellulose), but there has been little research on its polysaccharide counterpart (starch). This review paper highlighted the structure of starch, the context of amylose and amylopectin, and the extraction and modification of starch with their processes and limitations. Moreover, this paper describes nanofillers, intelligent pH-sensitive films, biofoams, aerogels of various types, bioplastics, and their precursors, including drying and manufacturing. The perspectives reveal the great potential of starch-based biomaterials in food, pharmaceuticals, biomedicine, and non-food applications.

“…They demonstrated that foam glass samples with smaller pores and a more uniform pore structure enhance mechanical properties. To investigate the effects of different foaming agents, Zhai et al [30] studied the physical and mechanical properties of foam glass materials at the molecular level. This approach provided a deeper understanding of the mechanism's characteristics associated with the foaming process.…”

Thermal Performance of Foam Glass Aggregate at Different Compaction Ratios

The use of glass waste in the construction industry has a high potential of leading to a higher recycling percentage. Foam glass aggregate (FGA) is around 98% recycled glass waste of various origins and has good insulation properties with big grain size distributions ranging between 10 mm and 60 mm. FGA has a wide range of applicability in the construction industry, which significantly differs from each implementation in the case of built-in conditions of the material. Therefore, investigating the impact of different compaction ratios, temperature, and relative humidity conditions on the thermal performance of such material is very important. In the present work, the samples of foam glass aggregates have been prepared with four different compaction ratios (10%, 20%, 30%, and 40%) to measure their impact on the material’s mechanical and thermal insulation properties. The obtained results revealed that the dry density property of the material linearly increased with elevated compaction ratios. In contrast, the submergence density did not follow the same trend behaviour under the same circumstances. The vertical strain of the foam glass aggregates decreased with increased compaction ratios, and a significant correlation behaviour was observed between the vertical strain and increased compaction ratios at high compressional loads. The material’s thermal conductivity increased with increasing compaction ratios in both 50% relative humidity and 95% relative humidity, while for the submergence condition, a significant decrease in their values was observed after compacting the material by 40%. The thermal conductivity is tested at 10 °C and 30 °C using the TLS and GHP methods. The thermal resistance of foam glass aggregate layers was calculated based on the measured results, showing an approximately linear decreasing trend with increasing compaction ratios. While the submerged foam glass aggregate samples demonstrated stable thermal resistance values at 30% compaction, by raising the compaction ratio to 40%, the material’s thermal resistance increased once again. The experimental results also found the temperature conversion coefficients, which can be used to convert the compacted FGA materials’ thermal conductivity to the temperature experienced in a different built-in state than the laboratory measurements. Our study demonstrates the broad usability of foam glass aggregate as a compacted thermal insulating layer in the building industry.

Methodologies based on Buckingham potential and mesh algorithms were employed[58].

Bio ceramics have enormous applications in the medical field as being used as implants. The base material in bioceramics is mostly calcium phosphate which comes in the form of hydroxyapatite (HAp) or Beta-tricalcium phosphate (β-TCP). The other materials are silica and alumina. The different blends of these bioceramics as well as bioglass are in use for medical implants. The use of simulation and modeling in determining and analysing the structure and function of these bioceramics is used for developing implants, scaffolds, and prosthetics as well as for analysing complex molecular interactions. The use of different molecular dynamics modeling techniques, Density Functional Theory, Finite Element Modeling, Artificial Neural Networks, etc is done in this regard. The results of these modeling and simulations are used for bone grafting, making scaffolds, making dental implants, healing damaged bones, 3D modeling, stress analysis, As removal, nanoindentation, etc. Some software like GROMACS, MEGACELL, and ANOVA is used for this purpose. Hydroxyapatite (HAp) was prepared from egg shells by various routes using hexane and acetic acid followed by heat treatment. Hap has a wide application in water treatment by removal of metal ions. XRD of the samples showed use of acetic acid followed by high temperature sintering leads to formation crystalline phases of HAp. Strong evidence of CaCO3 in calcite phase was obtained in other samples.
