Abstract: Disclosed is a membrane surface modification method. The method is applicable to a variety of hydrophobic membranes by doping selected inorganic particles. One act of the method involves the in-situ embedment of the inorganic particles onto the membrane surface by dispersing the particles in a non-solvent bath for polymer precipitation. Further membrane surface modification can be achieved by hydrothermally growing new inorganic phase on the embedded particles. The embedment of particles is for the subsequent phase growth.

Abstract: Sacrificial semiconductor material portions are connected by a sacrificial semiconductor line extending along a different horizontal direction and protruding into an underlying source conductive layer. After formation of a vertically alternating stack of insulating layers and spacer material layers, memory stack structures are formed through the vertically alternating stack and through the sacrificial semiconductor material portions. A backside trench can be formed through the vertically alternating stack employing the sacrificial semiconductor line as an etch stop structure. Source strap material portions providing lateral electrical contact to semiconductor channels of the memory stack structures can be formed by replacement of sacrificial semiconductor material portions and the sacrificial semiconductor line with source strap material portions. Structural-reinforcement portions may be employed to provide structural stability during the replacement process.

A method for controlling an aerial system including a central axis extending normal to a lateral plane of the aerial system, including: generating a first aerodynamic force with a set of rotors enclosed by a housing, detecting that an acute angle between the central axis and a gravity vector is greater than a threshold angle, and operating each rotor of the set of rotors to cooperatively generate a second aerodynamic force less than the first aerodynamic force with the set of rotors.

Abstract: The contact area between a source strap structure of a buried source layer and semiconductor channels within memory structures can be increased by laterally expanding a source-level volume in which the memory stack structures are formed. In one embodiment, sacrificial semiconductor pedestals can be formed in source-level memory openings prior to formation of a vertically alternating stack of insulating layers and sacrificial material layers. Memory openings can include bulging portions formed by removal of the sacrificial semiconductor pedestals. Memory stack structures can be formed with a greater sidewall surface area in the bulging portions to provide a greater contact area with the source strap structure. Alternatively, bottom portions of memory openings can be expanded selective to upper portions during, or after, formation of the memory openings to provide bulging portions and to increase the contact area with the source strap structure.
