Title: Hydraulic fracturing fluid
Inventor: LI LEIMING
IPC: C09K8/90
Filed: 2019-06-24
Abstract: A fracturing fluid including an aqueous base fluid having total dissolved solids between 100,000 mg/L and 400,000 mg/L, a polymer, a crosslinker, and at least one of a free amine and an alkaline earth oxide. In one example, the fracturing fluid may include a hydroxypropyl guar, a Zr crosslinker, and either a free amine such as triethylamine, or an alkaline earth oxide such as magnesium oxide. Optionally, the fracturing fluid may include a nanomaterial. Suitable example of a nanomaterial includes comprises ZrO 2  nanoparticles. The viscosity and viscosity lifetime of fracturing fluids with polymer, crosslinker, and either a free amine or an alkaline earth oxide are greater than the sum of the effects of the individual components taken separately. This synergistic effect offers significant, practical advantages, including the ability to reduce polymer loading to achieve a desired viscosity, and the ability to achieve better formation cleanup after the fracturing treatment.

Title: Method utilizing using post etch pattern encapsulation
Inventor: RALEY ANGELIQUE
IPC: H01L21/02
Filed: 2019-08-06
Abstract: A process is provided in which etched layer(s) are protected from residues or defects caused by or resulting from exposure to atmospheric conditions. Protection is provided through the formation of an encapsulation layer post etch. In one embodiment, the encapsulation is provided by a thin layer formed in an atomic layer deposition (ALD) process. The thin layer prevents the etched layer(s) from exposure to air. This encapsulation process may take place after the etch process thus allowing for substrates to be subsequently exposed to atmospheric conditions with little or no queue time constraints being needed for staging subsequent wet clean processing steps. In one embodiment, the encapsulation process may be performed with no vacuum break between the etch process and the encapsulation process. In one embodiment, the encapsulation film is compatible with subsequent wet process steps and can be removed during this wet process steps without adverse effects.

Title: Smart storage locker for mobile devices
Inventor: KIRCHHAUSEN HANS
IPC: G07C9/00
Filed: 2019-12-02
Abstract: A smart storage locker can be used to store an individual's mobile device while the individual is at work, school or another location where mobile devices should be restricted. The smart storage locker will therefore prevent the individual from carrying his or her mobile device while in such restricted environments. In addition to storing mobile devices, the smart storage locker can also be configured to automatically detect an individual's identity when the individual's mobile device is secured within the smart storage locker. This detection can then be employed to track when the individual is present at a particular location while not having access to, and therefore not using, his or her mobile device.
