Synthesis of nano-crystallite gypsum and bassanite from waste Pila globosa shells: crystallographic characterization

Abstract

For the first time, in this work, waste Pila globosa shells have been used to synthesize two industrially valuable materials, gypsum and bassanite.

Synthesis and characterization of nano-crystallite triple superphosphate from waste Pila globosa shells for sustainable industrial production

“…Different crystallographic parameters such as crystallite size, lattice parameters, dislocation density, microstrain, and crystallinity index were estimated employing eqn (6)–(9), the details of these equations being explained in previous literature. 20,25 The TSP crystals are triclinic crystals of the P 1̄(2) space group. This phosphate-based fertilizer is also known as hydrogen calcium phosphate hydrate with a molecular weight of 252.06 g mol −1 .…”

“…The details of the Monshi-Scherrer model can be found in the literature and can be expressed as eqn (S_6) (ESI †). 20,29 ESI, † Fig. S_2 presents the required graph for the TSP fertilizer and the computed crystallite size was 49 nm.…”

“…Recently, we have reported the application of P. globosa shells in the production of gypsum fertilizer. 20 Following our previous approach, in this research work, we have used P. globosa shells as an alternative source of raw material for the production of triple superphosphate (TSP). Moreover, we have also attempted to simplify the reaction procedure, aiming to increase the yield and thus minimize the production cost.…”

Synthesis and characterization of nano crystallite plaster of Paris prepared from waste eggshells and exploration of cytotoxicity, hemolysis and antimicrobial properties

“…A detailed explanation of the equation can be found in the literature. 32,33 The calculated specific surface area of the plaster of Paris was 48 m 2 g À1 . Specific surface area,…”

Biomedical competency of bassanite (plaster of Paris) synthesized from waste Pila globosa shells

“…14 Bassanite was synthesized from a well-known bioresources, Pila globosa, and the characterization of the prepared samples were reported earlier. 15 No biomedical applicability of the synthesized bassanite was reported yet whether it can be applied or not. The main concern of biomaterials is the interaction of materials with living cells.…”
