Abstract:
In an embodiment, a method for manufacturing a thin layer chromatography (“TLC”) plate is disclosed. The method includes forming a layer of elongated nanostructures (e.g., carbon nanotubes), and at least partially coating the elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. The stationary phase may be functionalized with hydroxyl groups by exposure to acidified water vapor or immersion in a concentrated acid bath (e.g., HCl and methanol). At least a portion of the elongated nanostructures may be removed after being coated. Embodiments for TLC plates and related methods are also disclosed.
Abstract:
Described is an improved method and system for remediating Frac water and other emulsions created during hydraulic fracturing. The system can include a first collection unit adapted to store contaminated Frac water, at least one pumping unit adapted to pump a portion of the contaminated Frac water, and a second collection unit for storing remediated Frac water. The system can further include a microwave separation technology (“MST”) unit, an ultra-violet light remediation (“UVLR”) unit, and a chemical additive unit adapted to reduce contamination levels of the contaminated Frac water. The MST unit can work alone, or in combination with the UVLR unit, the chemical additive unit, or both, to further reduce contamination levels of the contaminated Frac water. The system can be deployed at an onsite drilling facility or at a centralized offsite location. By reusing remediated Frac water, entities can realize significant cost savings and better environmental compliance.
Abstract:
In an embodiment, a method for manufacturing a thin layer chromatography (“TLC”) plate is disclosed. The method includes forming a layer of elongated nanostructures (e.g., carbon nanotubes), priming the elongated nanostructures with one or more adhesion priming layers, and at least partially coating the elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. The stationary phase may be functionalized with hydroxyl groups by exposure to a base or acid. The stationary phase may further be treated with a silane (e.g., an amino silane) to improve the performance of the TLC plate. Embodiments for TLC plates and related methods are also disclosed.

A method for preparing modified diamond particles for use in chromatography where hydroxyl groups at the diamond surfaces are reacted with a reactive molecule to introduce a desired functional group at the diamond surface.
Abstract:
Embodiments disclosed herein include graphitic stationary phase materials functionalized through a gas-phase functionalization reaction, as well as and methods for making and using these materials, including the use of these materials in separation technologies such as, but not limited to, chromatography and solid phase extraction. In an embodiment, a functionalized graphitic stationary phase material may be prepared from high surface area porous graphitic carbon and a radical forming volatilized functionalizing agent. The radical forming volatilized functionalizing agent produces an intermediate that forms a covalent bond with the surface of the porous graphitic material and imparts desired properties to the surface of the graphitic carbon.
Abstract:
A skateboard deck is formed of several layers pressed and bonded together. Apertures are formed through the bottom-most layers, and impact support members are arranged within the apertures. The impact support members are more rigid than the other portions of the skateboard deck, and provide localized impact support while allowing the remaining layers of the deck to retain their performance characteristics and feel while strengthening the most vulnerable areas of the deck.
