Asphalt-based roofing materials, such as shingles, are disclosed that include a band of a parting material. The asphalt-based roofing material includes at least one asphalt-coated substrate that defines a headlap portion and a tab portion each having opposed top and bottom surfaces; a layer of backdust applied to at least a portion of the bottom surface of the headlap portion and to at least a portion of the bottom surface of the tab portion; a release section of parting material applied to the layer of backdust, where the parting material is included in the in the range of 0.0005 kg/m.sup.2 to 1 kg/m.sup.2; and an adhesive.

Certain embodiments described herein are directed to electronic device screen covers that include one more bioactive materials. In some embodiments, the electronic device screen covers can be used with capacitive touch screens on electronic devices such as cellular phones, tablets, laptops, kiosk displays or other electronic devices that include screens. Methods of using the screen covers and screens to reduce spread of infections are also described.

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.
