Can we predict the presence of struvite stones based on clinical factors? [PDF]

Einstein (São Paulo)
Objective: This study aimed to evaluate whether clinical, laboratory, and radiological data could effectively identify struvite stones without the need for crystallographic analysis. Methods: Stone fragments obtained using endourological procedures were

Is Struvite a Prebiotic Mineral? [PDF]

Life, 2013
The prebiotic relevance of mineral struvite, MgNH4PO4·6H2O, was studied experimentally as a phosphorylating reagent and, theoretically, to understand the geochemical requirements for its formation.

Morphological and micro-tomographic study on evolution of struvite in synthetic urine infected with bacteria and investigation of its pathological biomineralization. [PDF]

PLoS ONE, 2018
Pathological biomineralization in the urinary system leads to urolithiasis. Formation of kidney stones involves a series of events during which they undergo morphological and mineralogical changes. We investigated the mineralization of biogenic struvite (

Struvite separation from wastewater and its use with sulfur-oxidizing bacteria improves phosphorus utilization in alkaline soil

Water Science and Technology, 2023
A major portion of phosphatic fertilizer comes from the limiting natural resource, rock phosphate, which demands a timely alternative. Struvite, a crystalline mineral of low solubility, is a worthwhile alternative.

First experimental evidence of the piezoelectric nature of struvite

Scientific Reports, 2021
In this paper, we present the first experimental evidence of the piezoelectric nature of struvite (MgNH4PO4·6H2O). Using a single diffusion gel growth technique, we have grown struvite crystals in the form of plane parallel plates.

XRD-Rietveld analysis as a tool for monitoring struvite analog precipitation from wastewater: P, Mg, N and K recovery for fertilizer production

Journal of Materials Research and Technology, 2020
The objective of this study was to select between four proposed synthesis conditions, which one would be the most propitious for struvite precipitation from wastewater and, on such product, detail its crystallochemical aspects using the Rietveld ...
