Chemistry Professor F. Jon Kull, at right, takes his class outside for a
dramatic display of chemicals producing an exothermic light show. The
thermite reaction of the ingredients produced heat, smoke, bright
light, and molten iron, accompanied by exclamations of "ooh" and "ah"
from the students.

This is a research graphic synopsis for my recent paper in Angew. Chem., and this was also
adopted by the journal as a frontpiece highlight. It was made by my co-author Sahag Voskian.
The long-range organization of a liquid crystal can be controlled by using an additive, which
consists of cholesterol units attached to a hydrazone switch. The acid/base-induced rotary
motion in the switch is transmitted to the self-assembled supramolecular host, wherein this
information is propagated and amplified. This process alters the photophysical properties of
the host, which results in the change of the readout color from purple to green.

Professor of Chemistry Joseph BelBruno’s Dartmouth lab conducted the
research on the technology behind the unique secondhand smoke
sensing device. Smaller and lighter than a cellphone and about the size
of a Matchbox car, the device uses polymer films to collect and
measure nicotine in the air.

Dartmouth has been awarded a $10-million, five-year grant from the Secure and
Trustworthy Cyberspace program of the National Science Foundation (NSF) to
support research into ways of safeguarding the confidentiality of personal health
and medical information as these records make the transition from paper files to
electronic systems. Computer scientist David Kotz leads a team that will conduct
research in the secure use of mobile and cloud technology for health and
wellness applications.

Dartmouth is one of 5 research institutions who are collaborating with
BioOne to publish Elementa, which is a new online open access journal
that began publishing in July 2013. Professors Anne Kapuscinski
(Environmental Studies) and David R. Peart (Biological Sciences) are on
the Elementa editorial team.

Station (right) and the South African Research Station SANAE IV (other two) in

of near-Earth space.
