For rats and other rodents, plastics are a popular menu item. Techmer Polymer Modifiers (www.techmerpm.com) has come up with a polymer additive that keeps these pests from nibbling on important plastics. The company's PM 12211E63 Repellent imbues polyolefins and other thermoplastics with a taste that rodents find repulsive. At the same time, the modifier is non-toxic to pets—as well as the rodents themselves. PM 12211E63 has seen use in wire and cable insulation, fiber-optic cables, plastic pipe, garbage containers, agricultural films, and outdoor furniture.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
