A Bright Future for Quantum Dots
The novel performance characteristics and tunability of quantum dots make them a promising nanomaterial in numerous emerging applications Quantum dots (QDs) represent a broad group of semiconducting nanoparticles that feature a unique combination of optical and electronic properties. For example,…
Distillation Column Internals: It’s What’s on the Inside that Counts
New column internals boost efficiency and improve reliability of distillation towers In the chemical process industries (CPI), the majority of separations are done via distillation columns. And, when the rest of the process relies upon those columns, inefficiencies, bottlenecks and…
Facts at your Fingertips: Convection versus Conduction Drying in Industry
Adjustment and control of moisture levels in solid materials is a critical aspect in the manufacture of many chemical products. Drying can be defined as the vaporization and removal of water or other liquids from a solution, suspension, or other…
Technology Profile: Production of Polyacrylonitrile Fibers
This column is based on “Polyacrylonitrile Production – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/polyacrylonitrile-production-cost.
