We present a feasible homopolar dynamo design consisting of a flat, multi-arm spiral coil, which is placed above a fast-spinning metal ring and connected to the latter by sliding liquid-metal electrical contacts.
The novel technology is made possible by the creation of an additional 1.5-mm-thick sliding shielding liquid, which flows internally, in order to dynamically adapt the window's solar transmittance.
There were 51 cytology slides (liquid-based preparations=22, smears=29), either Papanicolaou (n=26) or Diff Quik (n=25) stained.
LONDON — When the architect Tadao Ando's water feature, liquid sliding over glass lenses, opens outside the Connaught Hotel this summer, its cool elegance will mark a London renaissance.
With little plant life left to hold the sliding mountainsides in place, liquid earth buried roads and swept away houses and cabins.
With an increase in the sliding speed, a thicker liquid layer would be formed between the shearing surfaces, thus reducing the actual contact area and the friction force.
The complete separation of sliding surfaces by a liquid film under full hydrodynamic lubrication can allow bearings to operate indefinitely without any wear.
Variation in re-entrant surface curvatures determines the mesh's sensitivity to liquid-vapor surface tension, and changed the apparent contact angles and sliding angles for LST liquids.
The sliding wear of pressureless liquid-phase-sintered (PLPS) SiC ceramics under diesel fuel lubrication was investigated.
Compared with titanium, the PFPE infused fluorinated TiO2 surface presents lower contact angle hysteresis and sliding angle for various liquids.
