Industrial Uses of Biomass Energy: The Example of Brazil
Industrial Uses of Biomass Energy demonstrates
that energy-rich vegetation, biomass, is a key renewable energy resource for the
future. Brazil, uniquely, has a recent history of large-scale biomass industrial
uses that makes it a specially important test-bed both for the development of
biomass technology and its utilisation, and for understanding how this is shaped
by political and socio-economic forces. The book analyses the cause for this and
the alternatives. It is argued that Brazil's experience with the development for
industrial biomass use provides wider lessons and insights in the context of the
international movement for sustainable economic development.
This book is an
interdisciplinary, multi-author work, based upon a recently completed
international study by Brazilian and British experts and will prove a valuable
reference to all those working in this field.
E is for Energy.
Any form of energy can be transformed into
another form. When energy is in a form other than thermal energy, it may be
transformed with good or even perfect efficiency, to any other type of energy.
With thermal energy, however, there are often limits to the efficiency of the
conversion to other forms of energy, due to the second law of thermodynamics. As
an example, when oil reacts with oxygen, potential energy is released, since new
chemical bonds are formed in the products which are more stable than those in
the oil and oxygen. The released energy resulting from this process may be
converted directly to electricity (as in a fuel cell) with good efficiency.
Alternately it may be converted into thermal energy if the oil is simply burned.
In the latter case, however, some of the thermal energy can no longer be used to
perform work at that temperature, and is said to be "degraded." As such, it
exists in a form unavailable for further transformation. The remainder of the
thermal energy may be used to produce any other type of energy, such as
electricity. In all such energy transformation processes, the total energy
remains the same.
Chemical Engineering Lab
Work in the chemical lab is centered on the
chemical, biological and environmental aspects of energy technology and the
efficient use of our natural resources. This includes, for example, work on
renewable fuels such as methane, biodiesel and hydrogen, as well as research on
novel uses of geothermal effluents. Environmental monitoring, bioremediation and
the prevention of scaling and corrosion in geothermal power systems are further
examples of chemical energy

No.: 7220-79-3 (Trihydrate) Molecular Weight: 373.91 Chemical Formula:
C16H18ClN3S . 3H2O In biology methylene blue is used as a dye for a number of
different staining procedures, such as Wright's stain and Jenner's stain. Since
it is a temporary staining technique, methylene blue can also be used to examine
RNA or DNA under the microscope or in a gel: as an example, a solution of
methylene blue can be used to stain RNA on hybridization membranes in northern
blotting to verify the amount of nucleic acid present. While methylene blue is
not as sensitive as ethidium bromide, it is less toxic and it does not
intercalate in nucleic acid chains, thus avoiding interference with nucleic acid
retention on hybridization membranes or with the hybridization process itself.
It can also be used as an indicator to determine if a cell such as yeast is
alive or not. The blue indicator turns colorless indicating living cells.
However, if it stays blue it doesn't mean that the cell is dead or there are no
cells. Methylene blue can inhibit the respiration of the yeast as it picks up
hydrogen ions made during the process and the yeast cell cannot then use those
ions to release energy. In neuroscience, methylene blue can also serve as a
non-selective inhibitor of NO synthase. Wiki
