Sr/Na co-doped brushite coating on SiC–C/C with brushite seeds

Surface Engineering, 2019
Strontium/sodium (Sr/Na) co-doped brushite (SSCB) coatings were applied on SiC-modified carbon/carbon composites (SC) with undoped brushite seeds. Undoped brushite seeds were synthesised on SC by the microwave-assisted hydrothermal method, which facilitated the rapid formation of SSCB.

Dynamical model of brushite precipitation

Journal of Crystal Growth, 2007
The objectives of this work are twofold. From academic point of view the aim is to build a dynamical macro model to fit the material balance and explain the main kinetic mechanisms that govern the transformation of the hydroxyapatite (HAP) into brushite and the growth of brushite, based on laboratory experiments and collected database.

Reinforcement of osteosynthesis screws with brushite cement

Bone, 1999
The fixation of osteosynthesis screws remains a severe problem for fracture repair among osteoporotic patients. Polymethyl-methacrylate (PMMA) is routinely used to improve screw fixation, but this material has well-known drawbacks such as monomer toxicity, exothermic polymerization, and nonresorbability.

Brushite in the pulp of primary molars

Journal of Oral Pathology & Medicine, 1989
This study was undertaken to investigate the mineral phase of spherulitic calcifications discovered in the pulpous mesenchyme of human primary molars by microradiography. Analytical scanning electron microscopy and x‐ray diffraction disclosed that well‐crystallized brushite is the major compound of the spherulites.

Brushit in Harnsteinen

1978
Brushit (Ca HPO4· 2 H2 O) ist selten unter Harnsteinen anzutreffen. An 3000 Dunnschliffen von Harnsteinen haben wir nur 24 mal dieses Hydrogen-Calciumphosphatdihydrat gefunden (0,80%), und zwar 18 mal in Nieren- und Harnleitern und 5 mal in Blasensteinen. Das Vorhandensein von Brushit wurde in allen Fallen mit Hilfe der I.R. Spektroskopie bestatigt.

Risikofaktoren der Brushit-Steinbildung

Uro-News, 2015
Die Haufigkeit der Brushit-Steinerkrankung stieg in den vergangenen Jahrzehnten kontinuierlich an. Dennoch sind die zugrundeliegenden pathogenetischen Mechanismen und atiologischen Faktoren nur wenig bekannt. Zudem fehlen Informationen zum Stellenwert der Ernahrung.

Frozen delivery of brushite calcium phosphate cements

Acta Biomaterialia, 2008
Calcium phosphate cements typically harden following the combination of a calcium phosphate powder component with an aqueous solution to form a matrix consisting of hydroxyapatite or brushite. The mixing process can be very important to the mechanical properties exhibited by cement materials and consequently when used clinically, since they are usually

Molecular level interactions in brushite-aminoacids composites

Materials Science and Engineering: C, 2017
The interaction of aminoacids (Glycine, Proline, Lysine) with brushite based bone cements has been investigated by several techniques (FTIR spectroscopy, Thermogravimetry-TG, Scanning Electron Microscopy-SEM, mechanical properties studies), with the aim to elucidate the properties of the resulting composite materials and the interaction occurring at ...

Pancreatic calculi containing brushite: Ultrastructure and pathogenesis

Calcified Tissue International, 1986
Six pancreatic calculi were analyzed by X-ray powder diffraction and scanning electron microscopy. All were found to contain calcite; however, small amounts of two other morphologically distinct deposits containing only Ca were also detected in some of the stones. It is suggested that these substances may be vaterite and aragonite.

Brushite Boron Cement with Antibacterial Properties

Inorganic Materials: Applied Research
Boron-containing brushite cements (B-BC) for bone grafting based on B-substituted β-tricalcium phosphate (B-TCP) have been developed. The phase composition and microstructure of B-BC have been studied. It is shown that the crystalline phase of brushite is formed as a result of hardening of cements.
