Phosphorus retention by granulated apatite: assessing maximum retention capacity, kinetics and retention processes

open access: yesWater Science and Technology, 2021
Natural apatites have previously shown a great capacity for phosphate retention from wastewater. However, its fine particle size distribution may lead to a premature clogging of the filter.

A Bone Marrow–Mimetic Hydrogel Enables Dual‐Phase Hemostasis and Vascularized Osteogenesis for Cranial Defects

open access: yesAdvanced Science, EarlyView.
A biomimetic, fiber‐reinforced hydrogel (FE‐PDA@Fib/Gel‐TG) that enables dual‐phase cranial defect repair. The system provides: instant hemostasis in the early stage, and sustained co‐delivery of pro‐angiogenic and osteogenic signals for synergistic vascularized bone regeneration.

THE ROLE OF HALOGENS AND SULFUR IN APATITE FOR EVALUATION OF Cu-Ni, Fe-Ti AND Au ORES IN LATE PALAEOZOIC GABBROIDS OF THE WEST MAGNITOGORSK ZONE (SOUTH URALS) [PDF]

open access: yesМинералогия, 2015
Late Paleozoic gabbroids of West Magnitogorsk area were classified according to correlations between halogens and sulfur in apatites. For Hudolazovsky complex specialized in Cu-Ni mineralization apatites with the highest content of sulphate sulphur are ...

Multifunctionality of Nanosized Calcium Apatite Dual-Doped with Li+/Eu3+ Ions Related to Cell Culture Studies and Cytotoxicity Evaluation In Vitro

open access: yesBiomolecules, 2021
Li+/Eu3+ dual-doped calcium apatite analogues were fabricated using a microwave stimulated hydrothermal technique. XRPD, FT-IR, micro-Raman spectroscopy, TEM and SAED measurements indicated that obtained apatites are single-phased, crystallize with a ...

Thermochronology of the modern Indus River bedload: New insight into the controls on the marine stratigraphic record [PDF]

open access: yes, 2004
The Indus River is the only major drainage in the western Himalaya and delivers a long geological record of continental erosion to the Arabian Sea, which may be deciphered and used to reconstruct orogenic growth if the modern bedload can be related to ...

Natural Aging of Biomaterials in Ambient and Physiological Environments

open access: yesAdvanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

open access: yesAdvanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.
