Abstract: Additive particles may be employed in sufficient amounts to impart superhydrophobicity to a coating system in which the additive particles are incorporated. The additive particles include carrier microparticles and a dense plurality of nanoparticles adhered to the surfaces of the carrier microparticles (e.g., preferably by electrostatic deposition or covalent bonding). The additive particles are advantageously incorporated into a coating material (e.g., a polymeric material) in amounts sufficient to render a substrate surface superhydrophobic when coated with the coating material. The substrate may be rigid (e.g., glass, ceramic or metal) or flexible (e.g., a polymeric film or sheet or a fabric). In some preferred embodiments, both the microparticle and nanoparticles are formed of silica and are surface treated with a hydrophobic treatment so as to impart superhydrophobic properties thereto.

Abstract: An impact-resistant thermal sensitive material comprising at least one indicator dispersed throughout a heat-sensitive matrix material is provided. An article comprising the impact-resistant thermal sensitive material undergoes a permanent color change when exposed to a pre-determined temperature.

Abstract: Exemplary embodiments provide compositions and devices for hydrophobic coatings, and methods for making them. The hydrophobic coating can be formed from a coating solution including, for example, organically modified silicates (ormosils) mixed with coupling agents. Specifically, a sol-gel solution can be formed (e.g., at room temperature) including a plurality of alkoxy silane precursors that contains at least one glycidoxy alkoxy silane precursor. In an exemplary embodiment, the sol-gel solution can be a mixed sol-gel solution formed including a first solution mixed with a second solution. The first solution can include one or more alkoxy silane precursors, and the second solution can include at least one glycidoxy alkoxy silane precursor. A coupling agent can then be added and reacted (e.g., cross-linked) with the (mixed) sol-gel solution forming the coating solution, which can be applied onto a substrate that needs to be protected from corrosion or from chemical and/or biological agents.

Abstract: The present invention is directed toward a tunable dielectric device comprising: a substrate and an endohedral fullerene encapsulating trimetallic nitride template compound disposed on the substrate. The endohedral fullerene encapsulating trimetallic nitride template compound has a dipole moment that is oriented when a voltage of less than about 5 volts is applied thereto causing a change in the orientation of the dipole moment of the compound. The physical dimension of the compound is essentially unchanged.

Abstract: Organic light emitting devices are comprised of an organic charge carrier layer formed from a charge carrier material that is capable of forming a stable glass due to the presence of a compound having an asymmetric molecular structure in the charge carrier material. For example, the OLED may contain hole transporting layers comprised of compounds having an asymmetric molecular structure in which hole transporting substituents are asymmetrically located around a core atom or core chemical group. The core atom may be a nitrogen atom or the core chemical group may be comprised of a single phenylene group or a biphenylene group which is substituted with at least two hole transporting amine groups, wherein at least one of the amine groups is different from at least one other amine group.
