Design engineers are fuming mad about the lack of decent options for cadmium as a plating material. A couple made comments in a recent study conducted by the Reed Business Information Research Department for Design News. “We need an environmentally friendly replacement with decent cost and performance,” says an engineer who designs equipment for in house use. ”These days, cadmium is effectively banned for environmental reasons, but none of the possible replacements meet all the performance requirements.” Cadmium has been widely used as a plating material because it offers good corrosion resistance, cathodic protection of steel, galvanic compatibility with aluminum, as well as excellent lubricity. Cadmium can be dyed to many colors and can be used as a final finish or a paint base. Inhalation of cadmium-containing fumes can result in chemical pneumonitis, pulmonary edema, and death. Human exposures to environmental cadmium are primarily the result of the burning of fossil fuels and municipal wastes It’s one of six substances banned by the European Union’s Restriction on Hazardous Substances (RoHS) directive.

Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
