Artículo de publicación ISIPathological crystallization of calcium oxalate (CaOx) inside the urinary tract is called calculi or kidney stone (Urolithiasis). CaOx exhibits three crystalline types in nature: CaOx monohydrate COM, dihydrate COD and trihydrate COT. COD and COM are often found in urinary calculi, particularly COM. Electrocrystallization has been recently used to perform oriented crystallization of inorganic compounds such as Ca-salts. Although many mineralization methods exist, the mechanisms involved in the control of CaOx polymorphism still remain unclear. Herein, we induced selective electrocrystallization of COD by modifying the electrical current, time and electrochemical cell type. By combining above factors, we established an efficient method without the use of additives for stabilizing non-pathological CaOx crystals. We found notorious stabilization of CaOx polymorphisms with hierarchically complex shape with nano-organization assembly, size and aggregated crystalline particles. Our results demonstrated that, by using an optimized electrochemical approach, this technique could have great potential for studying the nucleation and crystal growth of CaOx through functionalized synthetic polymers, and to develop a novel pathway to evaluate new calculi preventing-compound inhibitors

ÖzBu çalışmada ultrasonik ses dalgası (USD) uygulanarak suda çözünebilir polielektrolit olan polivinilsülfonik asit (PVS) varlığında kalsiyum karbonat (CaCO 3 ) sentezlenmiştir. Sentezlenen CaCO 3 kristalleri X-ışınları kırınımı (XRD), taramaları elektron mikroskobu (SEM), Parçacık boyut dağılım analizi ve termogravimetrik analiz (TGA ve DTA) ile karakterize edilmiştir. 2 k Faktöriyel Tasarım uygulanarak, sonikatör genliğinin, polimer konsantrasyonunun ve USD uygulama zamanının elde edilen kalsiyum karbonat kristallerinin boyutuna etkisi incelenmiştir. Deneysel tasarım iki seviyede gerçekleştirilmiştir. Seçilen tüm proses parametrelerinin PVS varlığında elde edilen kalsiyum karbonatın parçacık boyutunda çok etkili olduğu görülmüştür. Parametrelerin parçacık boyutuna etkisi polimer konsantrasyonu > USD uygulama zamanı > sonikatör genliği şeklinde olduğu görülmüştür. The Synthesis and Characterization of Calcium Carbonate in the Presence of Polyelectrolyte and Experimental Design AbstractIn this study, calcium carbonate (CaCO 3 ) was synthesized by means of ultrasonic irradiation process in the presence of the water-soluble polyelectrolyte Poly(Vinyl Sulfonic Acid) (PVS). Synthesized CaCO 3 crystals were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Particle size distribution analysis and thermal analysis (TGA-DTA). The effects of the amplitude of sonicator, polymer concentration and the application time of ultrasound on the obtained CaCO 3 with respect to particle size of final product was investigated by applying the 2 k Factorial Design. The experimental design was studied at two levels. All the selected process parameters were found to be very effective on the particle size of calcium carbonate obtained in the presence of PVS. The order of factor strength on particle size was polymer concentration > the application time of ultrasound > the amplitude of sonicator.
