Science Equipment Takes Center Stage
VALDOSTA -- Valdosta State University invites community members
to explore the university’s collection of high-tech science
equipment during a ribbon cutting ceremony at 5 p.m. on Thursday,
April 15, in the Hugh C. Bailey Science Center atrium.
VSU President Patrick Schloss and the College of Arts and Sciences
will host the ceremony to unveil the Advanced Spectroscopy and
Biotechnical Facility, housed in the science center. Equipment for
the departments of Chemistry, Biology and Physics, Astronomy and
Geosciences was funded through the Major Scientific Equipment
funding pool, which Schloss established to purchase scientific
equipment that costs $50,000 or more.
Dr. Connie Richards, dean of the College of Arts and Sciences, said
the addition of more than half a million dollars worth of
sophisticated devices has expanded the university’s research
capabilities and exposed students to the latest scientific
technologies being used in a variety of practical and academic
arenas.
Following the ribbon cutting, guests are invited to roam through
laboratories, where they can observe as professors demonstrate the
complex machines and showcase their educational and practical
relevance.
Those interested in attending the ribbon cutting must RSVP by
Tuesday, April 13, to Mark Mears, administrative assistant to the
dean of the College of Arts and Sciences, at memears@valdosta.edu or
229-333-5699.
Read below for more information about the impressive technologies
to be revealed at Thursday's event.
BIOLOGY
Dr. John Elder, professor of biology, and a handful of students are
trained to use the LiCor 4300 Infrared Automated DNA Sequencing and
Genotyping System -- the only such sequencing and fingerprinting
equipment on a university campus from the University of Georgia to
Florida State. The genetic technology, which performs
microsatellite DNA fingerprinting and genotyping, enables students
to probe into biological and biochemical realms -- from gene study
to genomics research.
“The system brings cutting-edge DNA technology and research
capability to VSU and the region that was previously unavailable to
our faculty and students,” said Elder, who specializes in
population and molecular genetics. “Student training in these
molecular genetic techniques will significantly improve their
future opportunities in the field.”
Research projects underway that require the LiCor 4300, include DNA
microsatellite fingerprinting to study potentially endangered
minnow populations on Isle Royale National Wilderness area.
Researchers are also using the system’s microsatellite
fingerprinting to study population structures among locally
distributed water moccasin snakes. Elder said he hopes the addition
of the system will invite students and faculty from a variety of
disciplines to collaborate on future research projects.
“This particular system was intentionally designed to be rugged
enough to perform well under continuous teaching use by many
students,” said Elder. “Because the system does not use radio
isotopic labeling to detect DNA signals, it is very student
friendly avoiding possible radiation hazards and waste disposal
issues common to non-automated approaches.”
The Department of Biology will also be demonstrating the Spectra
Max M5e Multi-Detention Reader, which detects ultraviolet and
visible light absorbance as well as luminescence signals; the
Atomic Absorption Spectrometer, which detects low levels of a wide
range of elements; and the Avanti J26XP Centrifuge, which enables
students to gain experience in core molecular techniques.

CHEMISTRY
Dr. Tolulope Salami and his research team successfully prepared a
new two-dimensional compound (VALD-1, which denotes Valdosta State
University structure # 1). The structure was discovered using the
department’s latest technology the Rigaku MiniFlex II X-Ray
Diffractometer, which is capable of evaluating a compound without
destroying it. The synthesis structure and characterization of the
material was published in the November 2009 edition of Inorganic
Chemistry Communications.
Beyond research, the diffractomer has served a number of practical
applications. Dr. Jesse Spencer, professor of analytical chemistry,
said the compound identifier has aided in solving problems at VSU
and in the community since the university purchased the equipment
in October 2009.
“A vacuum line in our department kept getting clogged, so
maintenance brought us a sample, and we determined that it was a
copper hydroxide chloride, which meant there was too much hydrogen
chloride in the line, “ said Spencer, who has worked at VSU since
1984. “We also helped an Eagle Scout candidate determine that paint
in a house he was remodeling for his service-learning project was
not laced with lead.”
Salami said that both undergraduate and graduate students are using
this equipment, which is employed in a wide variety of fields. For
researchers, it provides structural determination of various
materials, such as porous materials used in drug delivery systems;
and for industries, it determines if products, such as cement and
chemicals, have the proper distribution of materials.
During the ribbon cutting, chemistry will also showcase the FT-NMR
Instrument System. The instrument analyzes samples from experiments
and confirms results prior to publication of research findings or
presentation of class projects. The Liquid Chromatography-Mass
Spectrometer enables faculty and students to analyze research
samples locally rather than sending them to outside labs. It
identifies and confirms the purity of novel compounds the
university is producing for cancer research.

department head Dr. Jim Baxter at 229-333-5798 or e-mail him at
jbaxter@valdosta.edu.
PHYSICS, ASTRONOMY & GEOSCIENCES
The purchase of nine illuminating Olympus Petrographic Microscopes
has enabled geosciences faculty and students to examine the mineral
characteristics of various rock formations through paper-thin
slices of geological material. Purchased in February, the
microscopes provide students and faculty researchers with
sophisticated renderings of rock, mineral and metal
compositions.
Dr. Mark Groszos, associate professor, oversees the eight advanced
polarizing student microscopes and one research/teaching model with
full digital imaging capabilities. Groszos said the department is
using the microscopes in an upper-level undergraduate class that
delves into the study of rocks and minerals. Several geosciences
students plan to use the microscopes in their senior projects, and
faculty members are incorporating the equipment into their research
programs.
“These microscopes fill what was previously a very large hole in
our geology curriculum,” Groszos said. “We intend to use the
microscopes in several lab classes and in numerous senior thesis
projects. We are currently teaching a trail class about optical
mineralogy and petrography, which is currently in the approval
process to add to the regular curriculum.”
Petrographic microscopes are used in all branches of the advanced
study of rocks, minerals, and other Earth materials. Chemists,
engineers, archaeologists, and forensic scientists also use the
microscopes to study crystalline material and metals.
The Department of Physics, Astronomy and Geosciences also acquired
the 500 MHz Digital Advanced Phosphor Tektonix Oscilloscope, which
analyzes the spectral properties of signals over a broad range of
frequencies. The Z-650 3D Printer creates high-resolution 3D models
of objects, such as fossils. The Ground-Penetrating Radar omits
radar pulses that create images of subsurface geological units,
such as aquifers and underground sinkholes. This unobtrusive method
allows scientists to observe an area -- such as buried structures,
cemeteries, bedrock and mines -- without disturbing the
ground.

department head Dr. Edward Chatelain at 229-333-5752 or e-mail him
