Provided is a PSA sheet that provides reliable adhesion even upon contact with grease. Provided is an adhesively double-faced PSA sheet having a PSA layer. The PSA sheet has an initial push-peel strength of 0.5 MPa or greater. It has an adhesive strength retention rate of 25% or higher, determined as the ratio of the push-peel strength at 24 hours after artificial sebum application to the push-peel strength before the artificial sebum application.

Disclosed herein is a multi-layer car mat liner. Further, the multi-layer car mat liner may include a first layer. Further, the first layer may include a knitted nylon fabric sheet. Further, a top surface of the first layer may include a plurality of longitudinal channels. Further, the plurality of longitudinal channels may be configured to trap particulate matter. Further, a second layer of the multi-layer car mat liner may include an absorbent sheet configured to absorb moisture. Further, a third layer of the multi-layer car mat liner may be a fiberglass mesh. Further, a fourth layer of the multi-layer car mat liner may be a thin sheath of rubber. Further, a bottom surface of the fourth layer may be configured to secure the multi-layer car mat liner to a vehicle floor.

An ultrasound device is for treatment or imaging of material such as biological tissue, and comprises a transducer arrangement and an acoustic coupling component positioned between the transducer arrangement and the material. The acoustic coupling component comprises an electroactive material actuator which uses an electroactive material composite. It may for example be controlled to implement frequency tuning of the acoustic coupling component. In this way, the acoustic coupling can be optimized for different frequencies of operation.

A cellular structure may include a plurality of cells each cell of the plurality of cells having a sixteen-cornered cross section. The sixteen-cornered cross section may include sixteen sides and sixteen corners. Each cell may include a plurality of longitudinal walls extending between a top and a bottom of the cell, the longitudinal walls intersecting to create corners of the cell.
