With ferrofluids, energy harvester designs no longer need solid structure. One example of ferrofluid based energy harvesting is to place the ferrofluid inside a container to use external mechanical vibrations to generate electricity inside a coil wrapped around the container surrounded by a permanent magnet.

In a diluted toning solution, selenium toning gives a red-brown tone, while a strong solution gives a purple-brown tone. The change in color depends upon the chemical make-up of the photographic emulsion being toned. Chloro-bromide papers change dramatically, whilst pure bromide papers change little. Fibre-based papers are more responsive to ...
Sachiko Kodama (born 1970) is a Japanese artist. She is best known for her artwork using ferrofluid, a dark colloidal suspension of magnetic nano-particles dispersed in solution which remains strongly magnetic in its fluid. [1]
Dye-sublimation printing (or dye-sub printing) is a term that covers several distinct digital computer printing techniques that involve using heat to transfer dye onto a substrate. The sublimation name was first applied because the dye was thought to make the transition between the solid and gas states without going through a liquid stage. This ...
After the digital design is printed onto sublimation transfer sheets, it is placed on a heat press along with the substrate to be sublimated. [citation needed] In order to transfer the image from the paper to the substrate, it requires a heat press process that is a combination of time, temperature and pressure.
This current causes the filament to reach the sublimation temperature of titanium, and hence the surrounding chamber walls become coated with a thin film of clean titanium. Since clean titanium is very reactive, components of the residual gas in the chamber which collide with the chamber wall are likely to react and to form a stable, solid product.
A sublimatory [1] [2] or sublimation apparatus is equipment, commonly laboratory glassware, for purification of compounds by selective sublimation. In principle, the operation resembles purification by distillation , except that the products do not pass through a liquid phase .
The drum then transfers the image onto paper which is passed through the machine by direct contact. Finally, the paper is passed onto a finisher, which uses heat to instantly fuse the toner that represents the image onto the paper. The laser is typically an aluminium gallium arsenide (AlGaAs) semiconductor laser), which emits red or infrared light.
