The project was established in 2011 with an emphasis on battery research, [4] but includes property calculations for many areas of clean energy systems such as photovoltaics, thermoelectric materials, and catalysts. [5]
Titanium dioxide is a bright white colour, but greater gains can be accomplished with materials that reflect more of the light parallel to projection axis and less off-axis. Frequently quoted gain levels of various materials range from 0.8 of light grey matte screens to 2.5 of the more
Various types of audiovisual materials range from film strips, microforms, slides, projected opaque materials, tape recordings, and flashcards. In the current digital world, audiovisual aids have grown exponentially with multimedia such as educational DVDs, PowerPoint, television educational series, YouTube, and other online materials.
The first transparent and flexible film base material was celluloid, which was discovered and refined for photographic use by John Carbutt, Hannibal Goodwin, and George Eastman. Eastman Kodak made celluloid film commercially available in 1889; Thomas Henry Blair, in 1891, was his first competitor. The stock had a frosted base to facilitate ...
The International Fusion Materials Irradiation Facility, also known as IFMIF, is a projected material testing facility in which candidate materials for the use in an energy producing fusion reactor can be fully qualified.
The projector would have positive transparencies on flexible material, "such as gelatine, mica, horn &c" to be "adjusted on a pair of endless metallic ribbons accurately punctured with small round holes" and guided past the lenses and shutters by pins on drums. Shorter sequences could be projected from glass discs instead of the films on drums.
Teaching materials can be pre-printed on plastic sheets, upon which the educator can directly write using a non-permanent, washable color marking pen. This saves time, since the transparency can be pre-printed and used repetitively, rather than having materials written manually before each class.
The opaque projector, or episcope is a device which displays opaque materials by shining a bright lamp onto the object from above. The episcope must be distinguished from the diascope , which is a projector used for projecting images of transparent objects (such as films), and from the epidiascope , which is capable of projecting images of both ...
