Computer-controlled operant chambers, made of aluminium and Plexiglas with grid floor (Coulbourn Instruments, Allentown, PA, USA), were placed in an experimental room, adjacent to the animal room.
So they experimented with new forms, materials and content: smoke paintings, kinetic art, rotating installations made of nails, glass or aluminium, black-and-white grid-like patterns and artificial light.
A drop was then allowed to dry on suitable substrates: aluminium stub for SEM, carbon coated copper grid for TEM, glass slide for optical microscopy and quartz substrate for XRD.
An analytical, numerical and experimental study is presented on the deagglomeration and dispersion of fine coal fly ash (CFA) reinforcing particles in an A380 aluminium matrix using a piston-actuated oscillating micro-grid mixing method with a specially designed grid geometry.
With suspended aluminium sheets, collages of magazine images and stretched wire grids, Gego's art conjures atmosphere out of thin air.
Greenland cannot be easily connected to other grids so turning this clean power into aluminium is the most practical way to export it.
Each box had three walls of sheet aluminium, a transparent plastic door as the fourth wall, a grid floor and an aluminium ceiling.
The Chinese government has started to discourage the expansion of energy-intensive industries, including aluminium and steelmaking, in an effort to ease the burden on its grid.
Nine evenly spaced square holes (2.5 × 2.5 × 4 cm) each containing a 3-W light were set into the curved aluminium wall at the rear of the box, 2 cm above the wire-grid floor.
