Gains in productivity and efficiency are possible when a coating or surface treatment provides functionalities beyond the usual protective and aesthetic properties. This realization has sparked great interest in functional coatings in recent years for applications that traditionally have not used paints or coatings. While great strides have been made in academic circles to understand the different surface phenomena of these so called ‘smart coatings’, commercial products to date have met with limited success because they are not engineered to meet all of the functional performance requirements… continue reading »
Core-shell Particles | Sulfide and Oxide Nanoparticles | Hollow Fibers
Core-Shell nanoparticles are composite particles where a core material is coated with a material of a different composition (shell), imparting unique functionalities that are otherwise unattainable for the individual materials. Such nanostructured particles have diverse applications. NEI Corporation has recently developed a patent pending, scalable process to produce core-shell nanoparticles. The process can be used to manufacture metallic and ceramic core-shell nanoparticles, such as metal / metal oxide and metal / metal boride core-shell nanoparticles. The versatility of the process allows core-shell nanoparticles to… continue reading »
A New Nanotechnology Approach for Micro-crack Prevention and Impact Resistance in Self-healing Fiber-Reinforced Composites
Composites are rapidly becoming the material of choice for various applications. The more familiar carbon fiber composites are used where a lightweight structural material is required. Airplanes, such as the Boeing Dreamliner, utilize fiber composites for their high strength to weight ratio, which ultimately decreases fuel consumption. This also translates to the automotive industry; the lighter the car is, the more energy efficient it can be. Another example is sporting goods… continue reading »
In general, the demand for smaller and lighter batteries has been growing drastically during the last decade. Conventional lead acid batteries have been in use since 1860 in stationary applications. Lead acid batteries are still widely used due to their low cost, matured state of development and ruggedness compared to other battery technologies. However, lead acid batteries (both flooded and VRLA) are heavier and bulkier. They also do not cycle well to meet some of the demanding new application needs.
Nickel‐cadmium batteries have been used in deep cycle applications. They are smaller and lighter compared to lead acid batteries. Large batteries have to have large amounts of free electrolyte within… continue reading »
