Abstract: A torque vectoring device for a vehicle is disclosed. The torque vectoring device includes: a differential; a first planetary gear set connected, at a first rotating element thereof, to a differential case of the differential; a second planetary gear set connected, at a first rotating element thereof, to a selected drive shaft that is one of two drive shafts coupled to the differential; a motor connected to a second rotating element of the first planetary gear set; and a selective fixing mechanism configured to selectively fix a second rotating element or a third rotating element of the second planetary gear set.

Abstract: An optical film for a display device, includes: a first refractive layer having an upper surface and a lower surface including first projections and second projections extending away from the lower surface in a first direction, the second projections having different heights than the first projections, the first projections having lateral sides with different angles of inclination that decrease in the first direction; and a second refractive layer disposed directly on the upper surface of the first refractive layer, the second refractive layer having a refractive index different from that of the first refractive layer.

Abstract: Polymer-infiltrated nanoparticle films (PINFs) that have high volume fractions (>50 vol %) of nanoparticles (NPs) possess enhanced properties making them ideal for various applications. Capillary rise infiltration (CaRI) of polymer and solvent-driven infiltration of polymer (SIP) into pre-assembled NP films have emerged as versatile approaches to fabricate PINFs. Although these methods are ideal for fabricating PINFs with homogenous structure, several applications including separations and photonic/optical coatings would benefit from a method that enables scalable manufacturing of heterostructured (i.e., films with variation in structural properties such as porosity, composition, refractive indices etc.) PINFs. In this work, a new technique is developed for fabricating heterostructured PINFs with cavities based on CaRI.
