ARES (Advanced Rheometric Expansion System) This rheometer was manufactured by Rheometric Scientific Inc., which is currently owned by TA Instruments. A direct-drive motor places a strain on the sample and an air bearing precision transducer then measures the stress. The rheometer has two transducers with a minimum torque of 2×10-7 N·m. It is a strain-controlled rheometer. It is equipped with a Neslab RTE-130 temperature control system. We have a special acid shield and fume system to create a dry, isolated environment for the rheometer to make measurements on SWNT/superacid mixtures.

The RDA III (Rheometric Dynamic Analyzer) is a controlled strain rheometer dedicated to high viscosity fluids and solids testing instead rotational and dynamic shear. With it’s durable ball bearing torque transducer, the product allows analysis of materials such as polymers, baby foods, inks, pharmaceutical gels, liquid crystals, crude oils, nd more solid-like materials. With a controlled temperature range of 25-50C, it is ideal for analyzing polymer melts and thermotropic liquid crystalline phase transitions. Parallel plates (25 mm and 40 mm) and Cone and Plate (25 mm and 40 mm) fixtures are available.

Fluid Processing Equipment

Two Flactek Speedmixers provide high speed, efficient mixing and compounding for liquid solutions, dispersions, and emulsions over a wide range of viscosities. The large Speedmixer (model DAC 600.1 FVZ) is capable of mixing samples (including container) of up to 600g at 2500rpm or less for 100 minutes. It includes the ability to create custom mixing programs for multi-stage mixing. The small Speedixer (model DAC 150.1 FVZ-K) is capable of mixing samples (including container) of up to 150g at speeds reaching 3500rpm for up to 5 minutes. Both utilize Flacktek’s Dual Asymmetric Centrifugal Mixing technology, which is a bladeless mixing technique that produces repeatable, bubble-free mixtures with high precision, repeatability, and speed.

Fiber Spinning Equipment

After mixing high-concentration CNT/superacid solutions, or “dopes”, these solutions are extruded through an air gap into a “coagulant” bath. In the air gap, the dope undergoes tensions, which further aligns the liquid crystalline CNT solution. In the coagulation bath, the acid is removed, and the CNTs coagulate to form a solid, aligned, neat fiber. Our group has a unique experimental setup for carrying out this extrusion process; syringe pumps are used to extrude the dope from the mixing vessel, and we have a  two-level arrangement where the dope is extruded downward from the first level through the air gap into the coagulation bath on the adjustable second level.

DrawDown Rod Coating

The Gardco Automatic Drawdown Machine is a benchtop device for draw down sample coatings with a high degree of reproducibility. With the Gardco Automatic Drawdown Machine the operator can get consistent, precision coating drawdowns every time. It can be use all different types of applicators–Microm applicators, Bird type, Wire wound rods, etc. The instrument can do coating with a speed range of 1.0 to 18.0 inches per second (IpS), in 0.1 inch/sec increments. There are four preset stroke lengths of 6, 9, 12 and 16 inches. The standard working surface is a 12 X 18 inch glass plate. An optional 12 X 18 inch vacuum plate can be used in place of the glass plate to accommodate different size paint charts. Standard 16″ OA Lab rods of either 1/2 or 3/8″ diameter can be used. The high temperature process furnace is used for conduction high temperature anneals of carbon and boron nitride based nanomaterials under controlled atmosphere conditions. Temperatures up to 1200C are available with an oxygen or nitrogen rich environment. A water bubbler is available for providing a steam-rich environment.

Freeze Drying Equipment

Free drying allows removal of water from a material without compromising the structure. The material is first frozen with liquid nitrogen, ten the sample vial is connected to the dryer, which reduces the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase. The Millrock benchtop freeze dryer lowers the temperature of the sample up to -45 degrees C and is equipped with a manifold to allow up to 6 samples to be dried at a time.
