[current news]- Nanotubes grown in the busy laboratory of associate chemistry professor Jie
Liu were crucial to IBM scientists' recent announcements of a
new source of light emission. Liu's lab is also working with a
California firm to pioneer use of these infinitesimally-thin
carbon tubes in place of copper contacts for computer chips.
These project are highlighted in a recent issue of Duke
Dialogue
- Weitao Yang, Philip Handler Professor of Chemistry, has been
awarded a prestigious von Humboldt Research Award
for Senior U.S. Scientists.
The Alexander von Humboldt Foundation grants up to
100 Humboldt Research Awards annually to
scientists and scholars from abroad with
internationally recognized academic
qualifications. The research award honours the
academic achievements of the award winner's
lifetime. Furthermore, award winners are invited
to carry out research projects of their own choice
in Germany in cooperation with colleagues for
periods of between six months and one year. - In the department's second Science paper in as many weeks, Jianping Lin, Ilya Balabin, and
David
Beratan report that structured water
molecules at protein interfaces have an unexpected
effect on the rates of electron transfer
processes. The results may account for a number of
previously unexplained observations of biological
electron transfer rates, and the work was
highlighted in a recent C&E News
article. A news release describing the
research has also been published.
- All are invited to attend the first annual Evening of Chemistry program,
Thursday, Dec. 8, from 7:30 to 9:00 PM.
Members of
the
chemistry club, graduate students, instructional staff, and Dr.
Warren will be performing a serious of chemical demonstrations.
About 150 students and their teachers in the research triangle
area will be attending. The event is free, but due to limited
seating it is a ticketed event. If you would like to attend and
have not yet put in your request for tickets please do so ASAP.
Send requests to Ken Lyle, kenneth.lyle@duke.edu Family
and friends are welcome. - The Franz Group has established in a recently
published paper that a relatively simple
peptide is sufficient to bind Cu(I) with an
affinity that corresponds well with its proposed
biological function of extracellular copper
acquisition. The results show that a
methionine-only binding site with three
methionines is sufficient for binding and
stabilizing Cu(I). This all-methionine
coordination motif represents an emerging
paradigm for bioinorganic copper.
- Jie Liu and collaborators at IBM report in the journal Science
that they have generated extra-bright
beams of infrared light from single-walled
carbon nanotubes. The new technique is more
efficient than many existing methods for producing
light and could have applications in
optoelectronics. For additional reports on this
work, click here

may lend insight into the epidemiology of skin
cancer. The work was done in collaboration with Glenn
Edwards at the Free Electron
Laser Laboratory at Duke and Robert
Nemanich of the physics department at NCSU.
- Chad Ray and Boris Akhremitchev have
recently demonstrated, using single-molecule
force spectroscopy, that dimers of specific
fragments of the protein alpha-Synuclein exist as
a mixture of dimeric conformations. The work
helps to shed light on the molecular basis of
Parkinson's disease, and a full article describing
the research can be found online at the Journal
of the American Chemical Society.

- With deep sadness, we announce that Howard Austin Strobel,
professor
emeritus of chemistry at Duke University, died on
June 4, 2005, at his home in Durham, NC. He was
84.
Born in Bremerton, Washington, he was the son of
the late Frank and Emma Spriegel Strobel. A
graduate of Washington State College (now
University), with a B.S. in chemistry and highest
honors, Strobel worked on the Manhattan Project at
Brown University in the group headed by Professor
Charles Kraus from July 1943 to the end of World
War II. With the end of the war, he continued the
physical chemistry project that he had started in
Brown in the Fall 1942 to receive a Ph.D. in 1947.
He stayed on at Brown for a one year post-doctoral
position before accepting a position in the Fall
of 1948 at Duke University as an Instructor in
Chemistry.
During his early years at Duke, he became a
full-fledged analytical chemist and came to
realize that achieving a mastery of all kinds of
measurements on substances and accompanying theory
of behavior might be achieved more completely by
taking a sophisticated approach to the
instrumentation involved. The product of those
insights, and a great deal of study, was the first
edition of the book, "Chemical Instrumentation, A
Systematic Approach to Instrumental Analysis,"
which was published by Addison-Wesley. A second
edition appeared in 1973 and a third, with Dr.
William H. Heineman as a co-author, was published
by Wiley-Interscience in 1989. His book has been
translated into several languages.
Strobel's professional career at Duke was split
between chemistry and academic administration. His
administrative work began when he accepted a
half-time appointment as an academic Dean in
Duke's undergraduate men's college in the fall of
1956, beginning a range of activities that over
the years accounted for more than one-third of his
time. He was assistant dean from 1956 to 64 and
again during 1972-82. He was associate dean in
1964-66. He was also acting associate dean and
acting assistant provost in 1974-75. Strobel
retired in 1990. Altogether the combination of
teaching, writing, administrative work,
sabbaticals abroad, and directive research for
many masters and doctoral students defined
Strobel's rewarding academic career that spanned
47 years at Duke University.
In 2001, more than a decade after his retirement,
he received the J.
Calvin Giddings Award for Excellence in
Education for writing Chemical
Instrumentation, a book that enhanced the
personal and professional development of
students in the study of analytical chemistry.
In his personal life, Strobel was a member of
Watts Street Baptist Church where he served as a
Deacon and Sunday school teacher. In addition to
education, Strobel loved hiking, travel, gardening
and photography.
In 2002, he was preceded in death by his wife of
49 years, Shirley Holcomb Strobel.
Surviving are two sons, Gary Dent Strobel and
wife, Sarah, of Mooresville, N.C., and Paul A.
Strobel, of Durham, NC; one daughter, Lynn S.
Helgeson and husband Steve, of Roanoke, Va.; and
two grandchildren, Zack and Scott Helgeson.

- Roald Hoffman, Frank H.T. Rhodes professor of humane letters and
professor of chemistry at Cornell and a recipient
of the 1981
Nobel Prize in Chemistry, will be presented
with an honorary degree as Doctor of Science at
the May,
2005 Commencement.
Born in Poland, Roald Hoffmann moved to the United
States in 1949.
After graduating from Columbia University, he
earned his doctorate in
chemistry at Harvard, and joined Cornell’s
chemistry department in
1965. He is now Cornell’s Frank H.T. Rhodes
professor of humane letters
and professor of chemistry. Dr. Hoffmann won the
Nobel Prize for
Chemistry in 1981 (with Kenichi Fukui) for
developing mathematical
theories to explain the behavior of atoms and
molecules, and for
co-authoring the Woodward-Hoffmann Rule, which
helps explain the
workings of chemical reactions.
Among Dr. Hoffmann’s other distinctions are the
Arthur C. Cope Award of
the American Chemical Society, the National Medal
of Science, the
National Academy of Sciences Award in the Chemical
Sciences, and the
Priestly Medal.
Dr. Hoffmann’s creativity extends beyond
chemistry. He helped spearhead
the project Chemistry Imagined, an unusual
collaboration in the realms
of art, science, and literature, which attempts to
reveal the
imaginative basis of molecular science. His book
The Same and Not the
Same explores the dualities that lie under the
surface of chemistry.
Old Wine, New Flasks: Reflections on Science and
Jewish Tradition,
which he co-authored, offers insights from the
intertwined voices of
science and religion. And his play Oxygen,
co-written with Carl
Djerasssi, Professor of Chemistry at Stanford
University, explores the
discovery of oxygen, along with deeper issues
concerning the conduct
of, and the motivations behind, science.
Throughout the years, Dr. Hoffmann has maintained
an interest in
literature, particularly German and Russian works.
He began to write
poetry in the mid 1970s; his first poem was
published in 1984, and the
first volume of his collected poems appeared three
years later. Since
then, his poems have appeared in many magazines,
have been collected in
several volumes, and have been translated into
several languages. “One
thing is certainly not true: that scientists have
some greater insight
into the workings of nature than poets,” he has
written.
“Interestingly, I find that many humanists deep
down feel that
scientists have such inner knowledge that is
barred to them. Perhaps we
scientists do, but in such carefully circumscribed
pieces of the
universe! Poetry soars…through a world we reveal
and make.”
His interest in popularizing science has taken him
to television, where
he presented a course in the broadcast The World
of Chemistry. The
series of twenty-six half-hour episodes aired on
PBS stations and
abroad.
“Roald Hoffmann has taught the chemical community
new and useful ways
to look at the geometry and reactivity of
molecules, from organic,
through inorganic, to infinitely extended
structures,” said Cornell’s
chemistry-department chair, after Dr. Hoffmann was
included among the
top seventy-five chemists of the past seventy-five
years in a special
issue of Chemical & Engineering News. “But as
important, his
teaching is not confined to his journals, nor even
to the freshman
introductory chemistry courses that he teaches
each year…. Roald is not
merely one of the most important chemists in the
past seventy-five
years, he is one of the most important educators.”
- We are pleased to announce that Warren Warren will join our faculty as a Professor of Chemistry.
Professor Warren's research focuses on the design
and application of what might best be called novel
pulsed techniques, using controlled radiation
fields to alter dynamics. It generally involves
an intimate mixture of theory and experiment, and
collaborations play an important role,
particularly for medical applications.
- We are pleased to announce that Jiyong Hong will be joining our faculty as an Assistant
Professor, arriving in August, 2005. Professor
Hong's research focuses on using chemical tools to
understand the signaling pathways underlying cell
and developmental biology. He is currently a
postdoctoral research associate in the chemistry
department of the Scripps Research Institute.
- Chemistry Graduate Student Chad Ray working with advisor
Boris Akhremitchev, won the Physical Chemistry
Poster Award at the spring 2005 national American

- Professor Katherine Franz has received an NSF CAREER award for her proposal
combining "Metal-Binding Studies of Phosphorylated
alpha-Synuclein Peptides" and "Graduate Student
Training in Communication, Leadership and
Professional Development". The Faculty Early
Career Development (CAREER) Program is a
Foundation-wide activity that offers the National
Science Foundation's most prestigious awards for
new faculty members. The CAREER program recognizes
and supports the early career-development
activities of those teacher-scholars who are most
likely to become the academic leaders of the 21st
century. CAREER awardees are selected on the basis
of creative career-development plans that
effectively integrate research and education
within the context of the mission of their
organization.
- Chemistry graduate student Yan Liu won Best Poster at the Richard Gilbert Graduate
Awards Symposium, hosted by the North
Carolina ACS Polymer Discussion Group and
sponsored by Lord
Corporation.
- Peter Agre, 2003 Nobel Laureate in Chemistry is joining the Duke University Medical Center as
the first Vice
Chancellor for Science and Technology. He will
officially leave his current position at Johns
Hopkins and join the Duke faculty on July 1. At
Duke, he plans to continue his research, but he
also intends to work with the local community and
national science coalitions to educate students
and the general population about health care issues.
