Spectroscopic laser (red ?beam) ?being used to measure properties of a semiconductor thin film used in solar cells. Solar cells ?use semiconductors to convert the energy in sunlight into electrical energy. The semiconductor thin ?film being investigated here, ?consists of a combination of the elements gallium, ?indium ?and phosphorus (GaInP). The efficiency of a solar cell is sensitive to its semiconducting properties, and these ?are determined by its chemical composition. Altering these properties changes a ?solar ?cell's efficiency.

Hemispherium building design. Wire-frame model of proposed office buildings at Longdenton, England, seen in the virtual reality (VR) Hemispherium. This is the world's finest immersive VR facility in 1999. The screen is a six metre wide dome, mounted vertically, giving an authentic 180 degree field of view in both horizontal and vertical planes. Seven projectors provide real-time computer graphics. The pilot (lower left) controls the view using a joystick. The wire-frame model shows the underlying geometry. As well as building design, this facility can also be used for pilot training and virtual tourism. The Hemispherium was opened in 1998 at Teesside University, England. - BS005048 - BS005063Keywords:3D Model, dreidimensional, Darstellung, Cave, Simulation, Computer, Architektur, Netz, Laser, Gitternetz, Virtuelle Realität

Profile of a female patient undergoing ophthalmic laser treatment. The head of the patient is secured to prevent movement; the laser is aimed using a retinal camera, and its beam is delivered in a series of pulses. Lasers have a variety of uses in ophthalmic surgery, including photo-cauterisation of blood vessels in retinopathy, and in the treatment of detached retinas. Such treatments do not usually require anaesthesia, and may be performed on an out- patient basis.

A high- power pulsed laser is aimed at a carbon target within a vacuum chamber (background). The vapourised refractory particles produced by the laser are then drawn away by a helium plasma to amass spectrometer for analysis. It was during this type of experiment that a 60-atom molecule of carbon was first discovered. In 1985, Kroto et al suggested a structure for the molecule, an icosahedron with hexagonal and pentagonal faces. This was named Buckminsterfullerene, and nicknamed 'Buckyball', after the architect whose geodesic domes the structure resembles. Simpler electric arc procedures are now used to make C60. - BS005048 - BS005063Keywords:BUCKYBALL, SYNTHESIS LASER, BUCKYBALL RESEARCH FULLERENES, PRODUCTION BUCKMINSTERFULLERENE HORIZONTAL CHEMISTRY LABORATORY
