Perigraftitis, an independent biologic complication associated with implants placed in grafted bone
Clinical Advances in Periodontics, EarlyView.Abstract Background Perigraftitis is a recently introduced concept describing biologic complications specifically associated with implants placed in grafted bone. It is characterized by inflammation resulting from bacterial colonization of grafted bone and/or residual graft particulates.

Optoelectronics and defect levels in hydroxyapatite by first-principles
, 2018 Hydroxyapatite (HAp) is an important component of mammal bones and teeth, being widely used in prosthetic implants. Despite the importance of HAp in medicine, several promising applications involving this material e.g.

ChemSusChem, Volume 18, Issue 6, March 15, 2025.The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

The Oxidation State of Sulfur in Lunar Apatite [PDF]
Lunar apatites contain hundreds to thousands of parts per million of sulfur. This is puzzling because lunar basalts are thought to form in low oxygen fugacity (f(sub O2)) conditions where sulfur can only exist in its reduced form (S2()), a substitution ...

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China
Geological Journal, EarlyView.Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Constraints on the thermal and tectonic evolution of Greymouth coalfield [PDF]
, 1999 The southern end of the Paparoa Range in Westland, South Island, New Zealand, comprises an asymmetrical, southward plunging, faulted (Brunner-Mt Davy) anticline, the eastern limb of which is common with the western limb of an asymmetrical (Grey Valley ...

Geological Journal, EarlyView.A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...
