Organotin patterning compositions have radiation sensitive ligands with acetal functional groups. Precursor compositions are compositions comprising (OR4)(OR3)R2CR1SnL3, where the R groups are substituted or unsubstituted hydrocarbyl groups and L is a hydrolysable ligand. The precursors can be formed into coating that can be patterned with radiation, in particular EUV radiation. Coatings formed with blended precursors with hydrocarbyl-based ligands with some having acetal groups and others lacking acetal groups can be particularly effective for improving positive tone patterning.

A self-disinfecting system can include a cladding having a flexible body that conforms to a substrate. The system can further include a disinfection means for disinfecting an exterior surface of the cladding. The disinfection means can be selected from a germicidal irradiation means, a photocatalytic disinfection means, or a chemical disinfection means for disinfecting the exterior surface of the cladding. The germicidal irradiation means can employ germicidal radiation from one or more locations within the body or the substrate to disinfect the cladding. The photocatalytic disinfection means can employ excitation radiation to produce reactive oxygen species using a photosensitizer incorporated into one or more polymeric layers of the body or a coating thereover to disinfect the cladding. The chemical disinfection means can employ a chemical disinfectant incorporated into the one-or-more polymeric layers of the body to disinfect the cladding.

A medical device has a base body on a delimiting surface of a room. The medical device furthermore has an additional body supported pivotably about a pivot axis on the base body. Thus, by pivoting the additional body about the pivot axis, it is possible to set a rotational position of the additional body relative to the base body. The additional body directly or indirectly carries a radiation source for emitting ionizing radiation. A data transmission element is on each of the base body and on the additional body in each case. The data transmission elements are arranged flush on the base body and on the additional body with respect to the pivot axis and are spaced apart from one another, seen in the direction of the pivot axis.

Antenna assemblies, such as RADAR sensor antenna assemblies, that incorporate destructive interference elements. In some embodiments, the assembly may comprise one or more waveguides, one or more antenna slots, and a plurality of destructive interference elements. The destructive interference elements may be configured to reduce backscatter radiation by contributing to destructive interference of electromagnetic waves incident upon the destructive interference elements. In some embodiments, the destructive interference elements may be defined and/or exposed by a plate that may be coupled with a waveguide block or another layer/component of the assembly.
