Abstract: Methods for introducing mesoporosity into zeolitic materials are described herein that employ an acid treatment, an optional surfactant treatment, and a base treatment without filtration or purification steps between the steps. In particular, the process generally involves subjecting a zeolitic material to an acid treatment followed by a surfactant treatment and base treatment. The methods can efficiently introduce mesoporosity into various zeolitic materials, such as zeolites.

Abstract: A system for minimizing driver distractions from a mobile device can include a blocking device and a blocking engine. The blocking device can include a first end, a second end, a cable, and a control board. The first end can include a first connector for coupling to a first port of a mobile device. The second end can include a second connector for coupling to a second port of a vehicle to receive a power signal from the vehicle. The cable can connect the first end to the second end. The control board can determine when movement of the vehicle exceeds a threshold value and transmit a launch signal. The blocking engine can receive the launch signal from the control board and launch a mobile application on the mobile device.

Abstract: Methods for introducing mesoporosity into zeolite materials that employ an acid pretreatment step are provided. By utilizing a non-acidic chelating agent during the acid treatment step, the zeolite material can be pretreated with a strong acid, often in higher concentrations or over shorter contact times, than had previously been contemplated. The resulting acid-treated mesoporous materials retain desirable properties, including Si/Al, UCS, and total mesopore and micropore volume. The ability to use a stronger acid without damaging the zeolite material results in a less expensive process capable of producing mesoporous zeolite materials suitable for a wide range of uses.

Additionally, such mesoporous zeolites can have a total 20 to 135 ? diameter mesopore volume of at least 0.05 cc/g.
