As demand for rare-earth metals in a wide range of technology applications continues to increase, efforts to reestablish mining and production of rare-earth elements (REEs) is underway outside China, currently the dominant force in REE production. Future supplies of REEs and the myriad products in which they appear will depend less on absolute geological reserves and global trade politics and more on...

Plastics are most commonly produced and sold in pellet form due to the superior handling characteristics of pellets in downstream applications. From the moment the polymer is pelletized from its molten state, the pellets or granules undergo a series of handling steps as they move from the producer to the consumer. For instance, post-pelletization steps include: • Hydraulic conveying • Drying...

The lifetime of steel bearings can be extended by up to eight times by a new synthetic diamond lubricant, according to its developer, NanoLube, Inc. (Lombard, Ill.; www.diamondlube.com). The lubricant consists of 0.1–4-nm diamond spheres that are dispersed in a light carrier oil (about 5 wt.%) and coated onto the bearings and other friction-prone surfaces of a machine. When the machine is activated...

One of the most important factors to consider when evaluating a specialty metal for use in valves, fittings and instrumentation is its corrosion resistance or corrosion rate of the metal in the target media. Each material discussed here has its own niche, and depending on the processing environment and the needs of the application, the metal’s strengths and weaknesses may or may not be suitable. In...

Cast parts, such as engine blocks, are typically made by pouring molten metal into so-called cores — sand-based molds that have internal passages for the component to be cast. Such casting cores are typically made by reacting sand with organic binders in a curing process. In recent years, industry has been seeking alternatives to organic binders to avoid releasing toxic emissions during curing. Last...

The exceptional properties of carbon nanotubes (CNTs), such as high tensile strength and high thermal and electrical conductivities, have suggested a number of applications, including lightweight materials for ballistics protection, actuators for muscles or artificial muscles, filaments for light sources, electrodes, super-capacitors, and flow sensors. So, many researchers have tried to prepare macroscopic...

Many methods have been developed for the encapsulation of "active" materials within a carrier nanoparticle, such as a polymer. These composite structures can be used in many biomedical, cosmetics, and food processing applications for the controlled release of pharmaceuticals, neutraceuticals, and flavors. However, most of the proposed encapsulation methods developed so far involve multiple steps...

A less-expensive way of making the raw materials for carbon anodes (for aluminum smelting) and graphite electrodes (used to make steel in electric arc furnaces) has been developed by West Virginia University (UWV; Morgantown, W.Va.; www.wvu.edu). The conventional starting materials for making electrodes are needle-grade coke (from petroleum) and binder pitch, which comes from petroleum distillation residue...

Frequently, in chemical processing equipment it is possible to place the shaft support bearings in the chemical that is being processed. In some cases, this precludes the use of oil- or grease-lubricated bearings because the operating conditions are not conducive to the use of such materials. For example, bearings that are lubricated with oil or grease can be problematic when submerged in liquids such as...
