Abstract: A system having a concealed communications element like a telecommunication antenna is described. More specifically, The system has a communications element that is concealed by a highly reflective multilayer polymer optical film 200. The first element of the multilayer polymer optical film is a core layer 202 that is made up of a multilayer optical stack. The multilayer optical stack of core layer 202 includes two alternating polymeric layers. The multilayer polymer optical film may optionally also include a protective layer 204 (for example, a hardcoat or an over laminate) that is positioned between the viewer and the core layer. The protective layer 204 may include one or more UV absorbers to aid in durability of the multilayer polymer optical film against UV-degradation. Multilayer polymer optical film 200 may optionally also include an adhesive layer 208 that is positioned between the core layer 202 and a surface onto which the multilayer polymer optical film is to be adhered.

Abstract: Articles are provided, including a porous elastomeric material having a first major surface and an elastomeric material integrated into the first major surface of the porous elastomeric material. The elastomeric material coating the first major surface, a first portion of the elastomeric material being disposed within a plurality of pores defined by the first major surface of the porous elastomeric material and extending into the plurality of pores to a depth of at least 300 micrometers (μm), wherein the first portion of the elastomeric material provides fluid communication through the porous elastomeric material via holes formed in the elastomeric material extending into the thickness of the porous elastomeric material through the voids of the pores of the elastomeric material. A method of making an article is also provided.

Abstract: A filtration media is disclosed comprising a hydrophobic monomer grafted onto a support, the hydrophobic monomer having the structure: CH2═CR4C(O)NHC(R1R1)(C(R1R1))nC(O)XR3 wherein n is an integer of 0 or 1; R1 is independently selected from at least one of: a hydrogen atom, alkyls, aryls, and alkylaryls, wherein the alkyls, aryls, and alkylaryls have a total of 10 carbon atoms or less; R3 is a hydrophobic group selected from at least one of: alkyls, aryls, alkylaryls and ethers, wherein the alkyls, aryls, alkylaryls and ethers have a total number of carbon atoms ranging from 4 to 30; R4 is H or CH3; X is O or NH. In some embodiments the hydrophobic monomer is derived from an amine or an alcohol (HXR3) that has a hydrophilicity index of 25 or less. Such media may be used in applications such as hydrophobic interaction chromatography.

Abstract translation: 其中n为0或1的整数; R 1独立地选自氢原子，烷基，芳基和烷基芳基中的至少一个，其中烷基，芳基和烷基芳基总共具有10个或更少的碳原子; R3是选自烷基，芳基，烷基芳基和醚中的至少一种的疏水基团，其中烷基，芳基，烷基芳基和醚的总碳原子数范围为4-30; R4是H或CH3; X是O或NH。 在一些实施方案中，疏水性单体衍生自亲水性指数为25以下的胺或醇（HXR3）。 这样的介质可以用于诸如疏水相互作用层析的应用中。
