Environmentally Benign Technology for Efficient Warm-White Light Emission
Nowadays efficient down conversion for white light emission is mainly based on rare-earth doped phosphors or cadmium-containing quantum dots. Although they exhibit high luminescence efficiency, the rare-earth mining and cadmium pollution have so far led to extremely high environmental cost, which conflicts the original purpose of pursuing efficient lighting. Here, we explore a new strategy to a...
متن کاملEnvironmentally Benign Manufacturing
How might mankind enjoy the fruits of an advanced civilization without endangering the viability of planet Earth for future generations? That is the fundamental challenge that we confront in the 21st century. In a time when the comforts and pleasures that can be derived from the products of modern technology are accessible for a significant portion of the world’s population, how can we manufact...
متن کاملEnvironmentally Benign Pyrotechnic Delays
Pyrotechnic delays are used in commercial and military items requiring a time delay between two energetic events. For example, US Army hand-held signals (HHS) use a delay element to properly sequence the expulsion of illuminating rounds at the rockets’ apex. Many military delay formulations contain barium, lead, chromates, and perchlorates. The US Army is reformulating pyrotechnic items to remo...
متن کاملTeaching Environmentally Benign Manufacturing
Teaching Environmentally Benign Manufacturing (EBM) presents the general challenges of teaching an application rather than a discipline. This is not too different from the challenges of teaching manufacturing about ten years ago. In that case we could rely heavily on successful practice and then develop principles to explain those successes. The principal success at that time was the Toyota Pro...
متن کاملEnvironmentally Benign Development of Photoresists in Supercritical Carbon Dioxide
Environmentally benign processes involving supercritical fluids have been investigated as alternatives to conventional solvents due to the increasing awareness of environmental issues. Carbon dioxide is considered to be a “green” solvent as it is nontoxic, nonflammable and non-reactive under most conditions. Supercritical carbon dioxide (scCO2) is a widely used solvent to enhance processing per...
