Researchers have developed a novel class of super-adhesive hydrogels, capable of maintaining exceptional stickiness in demanding wet environments, including saltwater. This breakthrough, detailed in Nature, leverages a data-driven approach that combines biological inspiration (data mining natural adhesive proteins) with artificial intelligence (machine learning) to design materials with unprecedented adhesive strength. These new hydrogels, exhibiting over 1 megapascal (MPa) of adhesion strength underwater – approximately "10 times stronger than most soft, sticky materials under the same conditions" – hold significant promise for diverse applications in "biomedical engineering, deep-sea exploration," and industrial repair. Listen to today's episode of Adhesion Matters to learn more about the connection with ducks.

This episode of Adhesion Matters examines the critical and evolving role of adhesives in the medical device industry, highlighting key technological advancements, market trends, and the strategic contributions of leading manufacturers. Adhesives have transitioned from simple bonding agents to indispensable functional components, enabling miniaturization, digital integration, and patient-centric designs. The industry is driven by stringent regulatory requirements, economic pressures, and a growing focus on sustainability. Manufacturers are providing comprehensive, high-performance adhesive solutions, coupled with technical expertise and integrated systems, to meet these complex demands and accelerate innovation in healthcare technology.

The art of cinematic disguise has been revolutionized by hyper-realistic silicone masks, which are now the gold standard for on-screen identity alteration, notably in the Mission: Impossible franchise. These masks are the result of a complex interplay between traditional artistry and advanced material science. Silicone's unique properties—including exceptional flexibility, tear resistance, dimensional stability, and biocompatibility—make it far superior to older materials like latex or gelatin, enabling masks to move naturally with an actor's expressions and withstand repeated use. While Mission: Impossible films depict instantaneous 3D printing of masks, the real-world process is a meticulous, multi-stage endeavor involving conceptualization, lifecasting, sculpting, mold making, and sophisticated casting and finishing techniques. Companies like Zhermack are crucial suppliers of specialized RTV-2 silicone resins and alginates that are foundational to achieving this unparalleled realism and durability.
