A method for controlling Aurelia spp. blooms in harbors includes: designing different sites at equal intervals in an area in spring, collecting ephyrae of Aurelia spp. with an I-type trawl net for zooplankton from bottom to surface, determining whether polyps of Aurelia spp. inhabit in the vicinity of the sites; seeking large floating substrates that the polyps attach to using scuba diving in the determined habitats of the polyps; dragging the substrates to a shore base and scraping off all organisms attached to bottom surfaces of the substrates in a physical manner, then air drying the substrates for 7 days or more; and applying an antifouling paint on the bottom surfaces of the dried substrates followed by drying, then returning the substrates back to their original sites in the sea to control the bloom of Aurelia spp. in the area.

A stretchable conductor of the present invention includes: a mixture which is configured of a stretchable portion made of an elastomer, and at least one type of conductive particles dispersed in the stretchable portion; and a conducting portion in which the conductive particles are aggregated in a higher concentration at one or a plurality of positions on an interface of the mixture than that at positions located in an inner portion of the mixture.

The invention relates to an energy efficient, environmentally favorable process for the preparation of brominated butyl rubbers, that uses a bromination agent and a oxidizing agent in order to enhance the utilization of bromine contained in the bromination agent. In a preferred embodiment a common medium for both solution polymerization and subsequent bromination of the rubber is employed.

A reflective coating device and method of use is provided. The device is comprised of a visibility-enhancing coating for retread tires, comprising a multi-layered reflective coating that aids in locating tire fragments on roadways. The device features a primer layer that strongly bonds to the tire rubber, followed by a reflective layer containing microglass beads and aluminum-coated prismatic particles within a binding matrix to ensure consistent reflectivity and durability under wear. High-contrast pigments and UV-stable agents improve visibility and prevent color fading, while optional photoluminescent materials provide passive glow in darkness. An optional topcoat layer shields the reflective layer from abrasion, moisture, and UV damage, enhancing the device's durability in harsh environments. A method for applying the device on tire surfaces ensures long-lasting performance, maintaining visibility under various conditions to enhance road safety.

A fluororubber composition having 10 to 60 parts by weight of wollastonite with an aspect ratio of 7 to 15 and 2 to 20 parts by weight of diatomaceous earth based on 100 parts by weight of fluororubber with a hardness Hs of 75 to 85. The fluororubber composition can be suitably used as a vulcanization molding material of an oil seal for both forward and reverse rotation that can maintain good fluid sealing in both forward and reverse operation even under high operating environment temperatures (e.g., 100 to 200 C.) and high rotational speeds (e.g., 8,000 to 15,000 rpm).
