    Abstract: A proppant comprises a particle and a polymeric coating disposed about the particle. The polymeric coating comprises the reaction product of a novolac polyol, an isocyanate, and an azole. The novolac polyol has a number average molecular weight of from about 200 to about 1000 g/mol. A method of forming the proppant comprises the steps of providing the particle, providing the novolac polyol, providing the isocyanate, and providing the azole. The method also includes the steps of combining the novolac polyol, the isocyanate, and the azole to react and form the polymeric coating and coating the particle with the polymeric coating to form the proppant.

    Abstract: A dust suppressing aggregate includes a core particle and a dust suppressing agent. The dust suppressing agent comprises polycarbodiimide and is disposed about the core particle for suppressing dusting of the core particle. A method of forming the dust suppressing aggregate includes the steps of reacting isocyanates in the presence of a catalyst to form the polycarbodiimide and encapsulating the core particle with the polycarbodiimide to form the dust suppressing agent. A system for producing the dust suppressing aggregate includes the core particle, the isocyanates, and the catalyst.

    Abstract: A receiver circuit includes a first slicer coupled to receive data signals from a signal path and a reference voltage from a reference voltage path that is separate from the signal path. The first slicer is configured output a logic value based on a comparison between a voltage of the data signal and the reference voltage. The receiver circuit further includes a reference voltage generator configured to generate the reference voltage. The reference voltage generator is configured to dynamically generate the reference voltage based on logic values of previously received signals during operation in a first mode. During operation in a second mode, the reference voltage generator is configured to generate and provide the reference voltage as a static voltage.
