  • Publication number: 20250060296
    Abstract: Sample cell devices and support assemblies are disclosed herein. The sample cell includes a novel concentric cylinder and coating design with a right-angle gear drive that enables enhanced rheological measurements in the 1-2 shear plane. The sample call can be used with a support assembly that enables efficient switching between the 2-3, 1-3 shear plane and the 1-2 shear plane without having to remove the sample and allowing for simultaneous imaging with, e.g., SANS or SAXS. Methods for using the sample cell and support assemblies in a 4D-SANS or 4D-SAXS sample environment are also disclosed.

  • Publication number: 20240272096
    Abstract: High-throughput high-pressure (HT HP) sample cells and sampling environments are disclosed herein. The HT HP sample cells include a top cell member and a bottom cell member that can be sealed together enclosing a sample in a pressure transmitter chamber. Further, the HT HP sample cells include a compressible, circular internal separator for compressing a sub-mL soft matter liquid sample. Further, the radiation beam windows of the HT HP sample cells are integral to the HT HP sample cell members. The novel and innovative HT HP sample cell design enables SANS measurements of the soft matter liquid sample when exposed to extreme temperatures and pressures without exhibiting leakage or cross-contamination of the soft matter liquid sample with the pressurizing fluid. Methods for using the HT HP sample cells in a pressurizing system for SANS analysis are also disclosed.

  • Patent number: 10716338
    Abstract: Articles of athletic garments, particularly sports bra and methods of treating the athletic garments with a shear thickening fluid (STF) are disclosed. The athletic garment comprises a STF treated fabric. The STF treated fabric in contact with the wearer's body part restricts movement of the body part when the shear stress exceeds the shear stress threshold value and stretches and conforms to the wearer's body part when the shear stress is less than the shear stress threshold value. The STF treatment method may include immersing the untreated fabric in a diluted STF bath, metering an amount of the fluid on the fabric, and removing the diluent from the treated fabric.
