Magnetite Biomineralization

nt study showed that most human brain tissues had a least five million single domain crystals per gram and in excess of 100 million crystals per for dura and pia. The crystals were in clumps of 50-100 particles. During biologically controlled mineralization of magnetite the organism makes use of cell activities to control the nucleation, growth, final place of deposit, and the morphology of the mineral. The process of biomineralization of magnetite commonly occurs in an isolated environment. The nucleation and growth of biominerals is dependent on the existence of a localized zone that enjoys and maintains adequate supersaturation. The two phases of iron that commonly feature in the process of magnetite biomineralization in bacteria are ferrihydrite and magnetite. In bacteria, magnetosome organelle is responsible for producing magnetite. The organelle is basically a biomineralized greigite or magnetite.
Magnetite Fe3O4 is a naturally occurring mineral. Scientists note that the mineral is one of the most magnetic minerals that naturally occur on earth. Research has shown that magnetite does not only occur naturally on the earth, it is also found in animal tissues. Indeed scientists note that almost all groups of organisms form one form or another of biominerals. Some of the organisms that have been found to precipitate magnetite include arthropods, chordates, and mollusks. Recent studies show that biominerals are found in humans such as in bones and teeth. The precipitation of magnetite in living organisms occurs through the biomineralisation process. This paper will discuss Magnetite biomineralization in light of its chemistry, occurrence, and crystallography among other issues.
Biomineralisation or biologically regulated mineralization is basically the process through which living organisms produce minerals according to Kirschvink and Hagadorn (2000). Weiner and Dove (2013) note that biomineral products are composites that comprise both organic and mineral ...Show more

Summary

So far, scientists note that roughly 60 naturally occurring minerals are precipitated by living organisms. In living organisms, magnetite is formed through the process of biomineralization…

Impact of climate change on timber engineering structures
Climate change presents a unique set of challenges and opportunities in the face of global warming and climate change. On the one hand, existing timber constructed structures are under increasing stress due to climate change while on the other hand a number of opportunities are offered by timber structures to slow down global warming.

The Economies Of Italy And Austria
Italy is a rather homogenous country both linguistically and religiously. However, it is quite diverse politically, culturally, and economically (McDonald, 1998). Italy’s population density ranks fifth-highest in Europe, with the largest minority group being the German-speaking people of the Bolzano Province and the Slovenes around Trieste.

Evolution and Extraterrestrial life
“On a more general level the very fact that alien life exists would mean that we are not the centre of the universe. While most religions now recognize that the earth is just a lump of rock, they still believe that WE human beings are the most important thing in creation, that we occupy a special place in God's plan.” (Riley, 2003) However, the presence of the extraterrestrial creatures endorses upon the very fact that God’s powers and schemes are not confined to human race or single planetary life only.

China will be the next global superpower
China becomes a prime candidate for this race exclusively on the basis of the presence of several factors. With the growing strength not just of China’s resources but also their economic wealth along with their impressive population size, military strength and their possession of sophisticated nuclear armaments China is well on its way towards becoming the next global superpower in the world.
