What can we learn from nature? The study of the physical, chemical
and structural properties of well-known minerals in the geo- and
biosphere creates new opportunities for innovative applications in
technology, environment or medicine. This book highlights today's
research on outstanding minerals such as garnets used as components
in all solid state batteries, delafossite formation during
wastewater treatment, monazites for the immobilization of high
level radioactive waste or hyroxylapatite as bioactive material for
medical implant applications. Contents Part I: High-technology
materials Lithium ion-conducting oxide garnets Olivine-type battery
materials Natural and synthetic zeolites Microstructure analysis of
chalcopyrite-type CuInSe2 and kesterite-type Cu2ZnSnSe4 absorber
layers in thin film solar cells Surface-engineered silica via
plasma polymer deposition Crystallographic symmetry analysis in
NiTi shape memory alloys Part II: Environmental mineralogy Gold,
silver, and copper in the geosphere and anthroposphere: can
industrial wastewater act as an anthropogenic resource? Applied
mineralogy for recovery from the accident of Fukushima Daiichi
Nuclear Power Station Phosphates as safe containers for
radionuclides Immobilization of high-level waste calcine (radwaste)
in perovskites Titanate ceramics for high-level nuclear waste
immobilization Part III: Biomineralization, biomimetics, and
medical mineralogy Patterns of mineral organization in carbonate
biological hard materials Sea urchin spines as role models for
biological design and integrative structures Nacre: a biomineral, a
natural biomaterial, and a source of bio-inspiration
Hydroxylapatite coatings: applied mineralogy research in the
bioceramics field A procedure to apply spectroscopic techniques in
the investigation of silica-bearing industrial materials
It is widely accepted that there is a relationship between ice
volume and the solar insolation in summer in the northern
hemisphere. The Earth's glacial cycles are driven by cyclic changes
in the Earth's orbital elements. This conclusion is based on the
strong coherence between the approx. 20000 and 40000 year spectral
components of ice volume and insolation (Milankovitch-curve)
records. These frequencies are determined by the variation of the
obliquity of the Earth's axis and by its position relative to the
Earth's orbit around the sun. The degree of sum mer insolation on
the Earth's northern Hemisphere is believed to be relevant to
climate because the North Atlantic is where cold saline water is
being formed. Present day deep water circulation is driven by salt
build-up in due to net evapora tion. In contrast, in the North
Pacific precipitation exceeds evaporation. Thus, deep water
transfers a surplus of salt from the N. Atlantic to the North
Pacific. This surface water delivers also oxygen to the deep ocean.
In contrast, upwelling deep water transfers nutrients from the deep
ocean to the surface water. Today the time of renewal of deep water
is in the order of 1000 years."
