Abstract: A deicing and snow melting device, for lowering the melting point of ice and snow, comprises of a plurality of pellets including an active ingredient. Each pellet of the plurality of pellets has at least an underside and a topside. The active ingredient is selected from the group consisting of chloride salts, organic compounds, alcohols or mixtures thereof. A base comprising a water-soluble sheet is joined to either one of the underside or topside of each pellet of the plurality of pellets.

Abstract: According to the invention, a melting and traction matrix for use on icy or wet surfaces comprising at least one melting agent and at least one substrate impregnated therewith and a method for making and using same are disclosed. The matrix is applied to surfaces where ice is present or anticipated. Upon surface contact, the substrate provides immediate traction and melting agent dissipates from the substrate. Further melting agent dissipates slowly by diffusion for a long-term, persistent effect. In combination with the substrate, the overall amount of melting agent may be controlled, thereby mitigating potential corrosive, toxic and adverse cosmetic and/or environmental effects. The remaining substrate after melting agent has totally diffused may provide longer traction benefit or may be swept away.

Abstract: Proppant compositions and methods for using same are disclosed herein. In particular, a proppant composition for use in hydraulic fracturing is disclosed herein. The proppant composition can contain a plurality of particulates and at least one particulate of the plurality of particulates containing a chemical treatment agent. The at least one particulate having a long term permeability measured in accordance with ISO 13503-5 at 7,500 psi of at least about 10 D. The at least one chemical treatment agent can separate from the at least one particulate when located inside a fracture of a subterranean formation after a period of time.

Abstract: Soft-matter technologies are essential for emerging applications in wearable computing, human-machine interaction, and soft robotics. However, as these technologies gain adoption in society and interact with unstructured environments, material and structure damage becomes inevitable. A robotic material that mimics soft tissues found in biological systems may be used to identify, compute, and respond to damage. This material includes liquid metal droplets dispersed in soft elastomers that rupture when damaged to create electrically conductive pathways that are identified with a soft active-matrix grid. These technologies may be used to autonomously identify damage, calculate severity, and respond to prevent failure within robotic systems.

Abstract: The present invention provides a composite molded body in which a rubber layer in the form of a thin film is formed on a surface of a resin molded body and a production method therefor. According to an embodiment of the present invention, a liquid composition containing a rubber component such as a rubber latex and a peroxide is applied to a surface of a resin molded body such as a polyamide-based resin having an amino group, causing crosslinking to occur in an uncrosslinked rubber layer and forming a crosslinked rubber layer in the form of a thin film. When a co-crosslinking agent is used in combination, adhesion to the resin molded body can be improved even when the thickness of the crosslinked rubber layer is small.
