D/H ratios of the inner Solar System [PDF]

, 2017
The original hydrogen isotope (D/H) ratios of different planetary bodies may indicate where each body formed in the Solar System. However, geological and atmospheric processes can alter these ratios through time.

Comparative efficacy of novel bioactive glass versus sodium fluoride toothpaste for dentin hypersensitivity

Journal of Periodontology, EarlyView.
Abstract Background This first‐in‐human clinical study aimed to evaluate the safety and efficacy of a bioglass incorporated in a toothpaste, in reducing dentin hypersensitivity (DH) compared to a sodium fluoride (NaF) toothpaste over a 2‐week period. Methods A double‐blind, randomized, parallel‐arm, proof‐of‐concept clinical trial was conducted with 46

Specific action of collector from phosphoric acid alkyl esters class in flotation of apatite-nepheline ores

Записки Горного института
Increasing amount of apatite-nepheline ores with complex mineral composition involved in processing, growing content of the associated minerals in ore which are similar in their floatability to apatite lead to the necessity of using highly selective ...

Exhumation of the Sierra de Cameros (Iberian Range, Spain): constraints from low-temperature thermochronology [PDF]

, 2008
We present new fission-track and (U–Th)/He data from apatite and zircon in order to reconstruct the exhumation of the Sierra de Cameros, in the northwestern part of Iberian Range, Spain. Zircon fission-track ages from samples from the depocentre of the

Comparison of Enamel, Dentin, and the Dentin–Enamel Junction in Horse, Dog, Wild Boar, and Macaque Using Confocal Raman Microscopy

Journal of Raman Spectroscopy, EarlyView.
Confocal Raman microscopy was used to map the dentin–enamel junction (DEJ) across four mammalian species. Chemical maps highlighted variations in mineral (phosphate/carbonate) and organic (amide/CH) phase. These results provide a comparative Raman framework to link tooth microchemistry with species‐specific structure and function.

Bioactive coating as a surface modification technique for biocompatible metallic implants: a review

Journal of Asian Ceramic Societies, 2019
Most high load-bearing implants are metallic alloys which contain toxic chemical components that might be released due to the corrosive environment of body fluids and load-bearing activity.

Current Trends and Future Prospects of Integrating Electrospinning With 3D Printing Techniques for Mimicking Bone Extracellular Matrix Scaffolds

Journal of Polymer Science, Volume 63, Issue 6, Page 1481-1504, 15 March 2025.
ABSTRACT This article presents a review of the recent findings on the combination of electrospun nanofibers and three‐dimensional (3D)‐printed structures for extracellular matrix (ECM) scaffolds for bone tissue engineering. We explore the synergy between electrospinning (ES), which produces highly porous, fibrous structures from materials like collagen

In situ Sr-Nd Isotopic Measurement of Apatite Using Laser Ablation Multi-collector Inductively Coupled Plasma-Mass Spectrometry

Yankuang ceshi, 2013
Apatite is a common accessory mineral, having a high Sr-Nd content and a low Rb content. The precise determination of micro-area Sr-Nd isotopic composition for apatite will provide important geochemical information for discussing the details of the ...

Apatite Stimulates the Deposition of Glomalin-Related Soil Protein in a Lowbush Blueberry Commercial Field

Agriculture, 2019
Many wind-sensitive and unproductive soils could benefit from increased glomalin-related soil protein (GRSP), an operationally defined soil protein pool known to improve soil quality and nutrient storage.

Pure Chitosan Microfluidic Spinning Affords Modular Core‐Sheath Fibers and Hand‐Crafted Scaffolds with Enhanced Fibroblast Compatibility

Small, EarlyView.
Microfluidic Wet Spinning affords highly resilient and biocompatible microfibers of pure chitosan without the use of any crosslinker. We produced microfibers both sheath and core of made of chitosan and another version with a chitosan sheath and chitin nanocrystals in the core.
