A slide ring material (SRM) paint is able to heal a majority of surface scratches by itself. When disturbed by minor abrasions, the paint’s cross-linked molecules retain mobility, and the oleophilic polyrotaxane coating redistributes its tension to slide back into place along the polymer chains, erasing the...

Springs, polymers, and pneumatic or hydraulic devices react to impacts, but a recently developed damping technology calculates and controls the forces that should be applied. Within the device, two electromagnets with different polarities are put in contact, and the repulsion force is used against the forces...

An organization seeks a low-cost way to render dirty, contaminant-filled water clean enough to use for washing or sanitary purposes. The treatment system should reduce dirt particles, lower pH levels, and remove surfactants like linear alkylbenzene sulphonate (LAS). A large water treatment plant...

A company is interested in licensing a film material that can be printed, sprayed, or transferred onto an anodized aluminum surface, such that the applied layer prevents oxygen from reaching and reacting with copper or other colored metals that are electro-deposited into the alumina pores. The...

A new lab at the National Institute of Standards and Technology (NIST) is dedicated to improving the quality of light that light-emitting diodes (LEDs) produce. NIST vision scientists Wendy Davis and Yoshi Ohno and a team of physicists created the NIST Spectrally Tunable Lighting Facility (STLF).
