This book introduces recent advances in understanding the crystal structure of carbonate hydroxylapatite (also known as bone mineral), which forms the hard tissue of bones and teeth. Bone mineral is the reservoir for carbon dioxide in the body and maintains the concentration of mineral ions in body fluids at homeostasis. The detailed structure of bone mineral has remained obscure more than 80 years after publication of the basic apatite structure, because of the nanoscale size and poor quality of bone mineral crystals. An entirely new approach to the determination of carbonate apatite...

This book explores vegetable fiber composite as an eco-friendly, biodegradable, and sustainable material that has many potential industrial applications. The use of vegetable fiber composite supports the sustainable development goals (SDGs) to utilize more sustainable and greener composite materials, which are also easy to handle and locally easily available with economical production costs. This book presents various types of vegetable fiber composite and its processing methods and treatments to obtain desirable properties for certain applications. The book caters to researchers and...

Over the last decades several researchers discovered that children, pupils and even young adults develop their own understanding of "how nature really works." These pre-concepts concerning combustion, gases or conservation of mass are brought into lectures and teachers have to diagnose and to reflect on them for better instruction. In addition, there are 'school-made misconceptions' concerning equilibrium, acid-base or redox reactions which originate from inappropriate curriculum and instruction materials. The primary goal of this monograph is to help teachers at universities, colleges and...
