Glass foams have great potential for several technological applications, for example, filters and thermal or acoustic insulators. Sodium hydroxide is an efficient foaming agent to obtain glass foams with high level of porosity. However, the control of variables that influences on structure, type, and size of pores of glass foams is necessary.This study evaluates the influence of composition and process parameters on glass foams based on soda-lime glass waste, sodium hydroxide, and borax. Experiments were conducted using factorial designs. According to the experimental conditions, bulk density varied from 0.16 to 0.79 g cm −3 and maximum porosity of 92%. Amounts of NaOH and borax in addition to sintering temperature are the main variables of the foaming process. The role of NaOH content is to reduce the density and closed porosity of glass foams associated with an increase in their open porosity. The addition of borax with low NaOH amount promoted densification and pore closure in glass foams. NaOH and borax content allows controlling the type of predominant porosity on foams (open or closed porosity). Glass foams were resistant to sulfuric acid, hydrochloric acid, and nitric acid in diluted solutions. These results allow controlling the pore structure of glass foams for different applications.

The Biginelli product, dihydropyrimidinone (DHPM) core, and its derivatives are of immense biological importance. There are several methods reported as modifications to the original Biginelli reaction. Among them, many involve the use of different catalysts. Also, among the advancements that have been made to the Biginelli reaction, improvements in product yields, less hazardous reaction conditions, and simplified isolation of products from the reaction predominate. Recently, solid-phase synthetic protocols have attracted the research community for improved yields, simplified product purification, recyclability of the solid support, which forms a special economic approach for Biginelli reaction. The present Review highlights the role of polymer-supported catalysts in Biginelli reaction, which may involve organic, inorganic, or hybrid polymers as support for catalysts. A few of the schemes involve magnetically recoverable catalysts where work up provides green approach relative to traditional methods. Some research groups used polymer−catalyst nanocomposites and polymer-supported ionic liquids as catalyst. Solvent-free, an ultrasound or microwave-assisted Biginelli reactions with polymer-supported catalysts are also reported.

“…From another point of view, given the increasing consumption of energy and products in the world, one of the most useful ways is to use waste materials in line with the principles of green chemistry. For instance, applying waste materials in catalytic field can be a constructive step as far as environment and the economy are concerned . The wastes can either be used directly as a catalyst or be converted into active catalysts by modifying .…”

From the perspective of green chemistry, in catalytic systems, being low cost and eco‐friendly, in addition to high chemical and thermal stability, are requirements of support materials. In this regard, we used apple seed starch as an accessible, nontoxic, and cost‐effective support material. In order to take advantage of magnetic separation, the magnetite nanoparticles were chosen as an ideal pair for apple seed starch. Furthermore, during the Schiff base reaction, the magnetic apple seed starch was functionalized with 2,2′‐furil along with amine functionality to be used as a bio‐support for immobilization of cobalt. The introduction of cobalt had a significant effect on the greenness of the catalyst and reducing its price. FT‐IR, TGA, XRD, FE‐SEM, TEM, VSM, ninhydrin test, element mapping, AAS, and EDX analysis were applied to characterize the newly prepared catalyst. The effectiveness of this novel Schiff base supported catalyst was evaluated in the Mizoroki–Heck and the Suzuki–Miyaura coupling reactions. High reactivity and selectivity were among the most prominent characteristics of the catalyst as compared to previously reported catalysts. The longevity test and hot filtration showed the ability to use the catalyst at least 5 times and negligible cobalt leaching during the reaction, respectively. This work is the first report on the usage of apple seed starch as a supporting catalyst and 2,2′‐furil as a ligand in the catalyst modifications and catalytic activity. Accordingly, this can be the beginning of an attractive way in the design and synthesis of heterogeneous catalysts.
