The worldwide market for portable electronic devices is quickly growing. These
devices are predominantly battery-driv-en, and a challenge looms for maintaining, charging and disposing of these
millions of batteries. Lawrence Berkeley
National Laboratory’s Bacteriophage
Power Generator offers a potential
alternative. The technology relies on a
bacterial virus that exhibits piezoelectric
properties. The M13 bacteriophage (or
phage) infects bacteria only, is harmless
to humans and is composed of DNA.
Proteins encapsulate the DNA and form
elongated piezoelectric nanofibers.
Researchers genetically modified the
DNA structure of the virus by adding
four negatively charged amino-acid residues to one end of the helical proteins
that coat the virus. These residues increase the charge difference between the
proteins’ positive and negative ends, boosting the voltage produced by the
virus. The viruses spontaneously organize into a multi-layered film, which
is sandwiched between two gold-plated electrodes and connected by wires
to external devices. When pressure is applied to the phage-based genera-
tor, it produces up to 6 nA of current and 400 mV of potential—two-or-
ders-of-magnitude higher in power than other commercial generators.

A New Take on Butanol
The alcohol compound butanol has
many attractive characteristics in
comparison with common ethanol,
including a higher heating value and
compatibility with existing gasoline
engines. Currently processed from
fossil fuels, butanol has the potential
to be created through fermentation.
Acetone-butanol-ethanol (ABE fermentation has existed for decades,
but has not succeeded as a scalable,
industrial method. Industrial Technology Research Institute (ITRI) has developed a butanol production technology, called ButyFix, which is designed to meet real-world production requirements and also fulfill biofuel's mission to reduce greenhouse gas emissions.
ButyFix functions on two key chemical processes: cellulose and hemicel-
lulose hydrolysis conversion into sugar and sugar fermentation into butyrate.
The technology produces butanol by first fermenting sugars to produce
butyrate. To create butanol from butyrate, ITRI uses proprietary processes to
regulate certain genes in specially adapted microorganisms and re-directs carbon dioxide generated during fermentation to the desired pathway where the
carbon dioxide can be re-utilized, achieving a high yield of butyrate. ITRI has
demonstrated that ButyFix generates a solvent yield of 0.70g/g-sugar—a 94%
conversion of carbon. this result corresponds to a 57% increase over traditional ABE processes.

The molecular property spectrometer MPS™ is a silicon chip capable of making
thousands of measurements mapped to a core set of fundamental molecular
properties. It is being offered here as the core of a configurable measurement
and analysis platform (C-MAP™) for laboratory, industrial, and pilot deployment
testing, analysis, evaluation or product development. Future products can be
configured and adapted from this platform system, miniaturized for specific ap-
plications, and deployed into those applications since the MPS has very simple
core components, namely an OMAP processor, silicon chip and heated intake.
