Sintering and dissolution of bone ash-derived hydroxyapatite
Metals and Materials International, 2010Bone ash-derived hydroxyapatite (HA) ceramics were prepared by pressureless sintering and hot pressing, and their dissolution behavior was examined in buffered water. HA powder was obtained by soaking bone ash in a 0.1M NaOH solution at 80 °C, followed by calcination at 1000 °C to completely remove the organic material.

Measurement of low-level radioactivity in bone ash
Journal of Environmental Radioactivity, 1999Abstract Bone is a critical organ for the accumulation of many radionuclides including 90 Sr and the actinides. The National Institute of Standards and Technology (0NIST) has prepared bone ash samples with a view to producing a standard reference material. The Institute for Reference Materials and Measurements (IRMM) participated in the analysis for

Bone Toothbrush Handles in Chinese Tang Dynasty Ash Pits
Journal of the History of DentistryChina has been recognized as an important birthplace of dentistry in the world. The bone toothbrush from ash pits in the museum of the Chengdu University of Traditional Chinese Medicine confirms that the Chinese had the awareness of cleaning their teeth and the tools to do for over 1000 years.

Percentage ash content of nonhuman primate long limb bones
American Journal of Physical Anthropology, 1979AbstractTrotter and Hixon ('76) and Vose and Roach ('72) presented conflicting data about percentage ash content of the long limb bones of M. mulatta and M. nemestrina. The suggestion of Trotter and Hixon ('76) that this discrepancy was due to methods of preparing the bone prior to ashing, rather than to species differences, was tested using data ...

Interrelationships of bone ash and whole bone properties in the lactating and parous rat
Calcified Tissue International, 1987Several investigators have studied the mechanical properties of long bones of rats and have found that bone strength may be associated with bone mineral content. In this study we examined further the interrelationships of whole bone properties and bone ash weight of the rat femur.

The influence of bone volume fraction and ash fraction on bone strength and modulus
Bone, 2001Although bone strength and modulus are known to be influenced by both volume fraction and mineral content (ash fraction), the relative influence of these two parameters remains unknown. Single-parameter power law functions are used widely to relate bone volume or ash fraction to bone strength and elastic modulus. In this study we evaluate the potential

Radioactivity of Soils, Plant Ashes and Animal Bones
Nature, 1959Alpha-activity measurements were made of bones of a New Zealand cow and ewe and their offspring. Also some observations on the influence of superphosphate on plant and animal uptake of radioactivity are made. (T.R.H.)

From bone to ash: Compositional and structural studies of burned bone
2014The composition and structure of experimentally heated modern bone and cremated bone fragments from various archaeological sites were analysed by Fourier Transform Infrared Spectroscopy (FTIR) in Attenuated Total Reflectance (ATR) mode before and after pre-treatment with acetic acid.
