The Science Center

This building with five floors opened in 1968, but was gutted and thoroughly renovated in 1996-1998. Further background is covered in the Department history Chapter 3. Biology, Chemistry, Geology, and Physics Department are housed in part here, together with IT personnel. The building is pictured before extensive landscaping was added.

Faculty members here: Dr's. Eddaoudi, Johnston, Larsen, Lewis, Malik, Martin, Musselman, O’Malley and Rogers.

At the Science Center steps take some time to look east at the fountain

This is part of Warner Garden (with support provided by Warner Communications). Mr. Douglas Hollis’s creation is entitled “Unspecific Gravity” A representation of water molecules may also be note . These will rotate provided sufficiently clean water is available.

Turning around, walk up the Science Center steps or take the ramp on the left (south) side of the building ...

Science Center steps --- view from fountain

 

Walk through the doors to the entrance/hallway

Enter from the front entrance to the second floor (the first floor used to be called the Basement) and take the stairs or elevator to the fourth floor where Chemistry and Physics faculty and students have offices and laboratories.

Walk down the hallway (going west)...

Second Floor Hallway

IT offices and certain advising offices are on the right side. The Dean’s Conference room is on your left just beyond the newspaper box on the left. The stairs and two elevators are located at the end of the hallway .

Once you are on the fourth floor notice that the Core Facility is in the west hallway…

Solid State Structure and Characterization core containing single crystal X-ray diffraction and X-ray powder diffractions capabilities, sorption balances, DSC and GCMS. Various optical spectrometers are housed on the fourth floor near chemistry laboratories and faculty offices .

This Core Facility is heavily used by members of the SMMARTT Center (Smart Metal- organic Materials Advanced Research and Technology Transfer), Dr. M. J. Zaworotko is Center Director.

Single Crystal X-Ray Diffraction Unit

The X-Ray Facility has a single crystal x-ray diffractometer and a powder x-ray diffractometer together with supporting equipment (shown below).

F-T Infrared Spectrometer

Ultraviolet Spectrophotometer

TGA, Thermogravimetric Apparatus

Thermogravimetric analysis is used to determine the changes in weight of a sample as a function of change in temperature, as a means of characterizing properties of the substance. Loss of weight may be associated, for example, with loss of water. TGA is also used to determine the amount of inorganic or organic components in materials or the degradation temperatures of polymers.

Differential Scanning Calorimeter

A differential scanning calorimeter measures the difference in the heat required to increase the temperature of a sample in comparison with a standard as a function of temperature. The differences may be used in detecting differences in composition and in measuring the of crystallinity or oxidation of a material.

Glove box

A glove box permits manipulations in a controlled environment, e.g. moisture-free or even an oxygen-free environment when working with sensitive compounds.

Pressurization apparatus

This apparatus associated with SMMARTT Center is useful for adding carbon dioxide to crystals as a convenient method of synthesis.

Proceed down the west hallway, turn right end see the portraits on the south wall

Fourth floor north hallway

We’re on the way to laboratories, and we just passed pictures (from right) of the first full professor of chemistry (Dr. Theodore Ashford), the first distinguished professor of chemistry (Dr.W. Conard Fernelius), and the first two Department Chairs: Dr P. Calvin Maybury ( 1963-74 ) and Dr. Terence C. Owen ( 1974-78).

Take time to visit some laboratories…

Thermal Photonics Laboratory – Dr. Randy Larsen

Biophysical chemistry, protein structure/function, time-resolved optical spectroscopy. We utilize both traditional time resolved optical spectroscopies (nanosecond transient absorption/fluorescence) together with novel photothermal methods (photoacoustic calorimetry and photothermal beam deflection).

Photoacoustic calorimeter. We caught William Maza as he was contemplating the experimental design for his next procedure using the calorimeter.

Analytical Separations Laboratory, Dr. Abdul Malik

Dr. Malik's research activities are focused on separations chemistry. His research group is engaged in developing advanced technology for high-performance differential migration micro separation techniques in analytical chemistry. Recently Dr. Malik has initiated a new direction in column technology research: sol-gel chemistry-based advanced column technology for micro separation techniques. This novel approach to column technology allows for the creation of tailor-made surfaces and monolithic separation beds to achieve wide range of selectivity and solute migration characteristics.

Dr. Malik’s advisee, Youcelyne Larose, next to gravity feed reservoir and HPLC unit used for testing his notable analytical separation columns.

Proceeding down the hallway, and making two right turns, we pass a Chemical Research Group room (Dr. Jennifer Lewis), and then see:

The Polarized Specular Reflectance Microscopy Laboratory, Dr. Ron Musselman

The Department's Polarized Specular Reflectance UV/vis/IR Spectrophotometer, built by Dr. Ronald Musselman, gives us the unique capability to study the UV/vis spectra of porphyrins and other molecules inside of or comprising open metal-organic frameworks (MOF's), an area of intense activity in the department. Typical UV/vis spectro -photometers require a sample in solution, but this instrument allows us to observe spectra of single crystals as small as 0.03 mm, which is sometimes as large as MOF's grow. We are also able to determine the chemical environment around the encapsulated molecules. The polarization aspect allows more detailed information about transitions than available via solution spectroscopy and allows the identification of preferred orientations of molecules even if too loosely-held for X-ray determinations.

Now it’s time to visit BSF. Return to the front of SCA, then walk past Warner Garden, and go east of the Chemistry Building and see...
