Because these structures often had sloping roofs, the word was connected with the French word pente, "slope," and beginning in the 1500s, the second part of the word began to be associated with the word house, in its meaning "a building for human use," and spellings like penthouse begin to become common. The use of the term with reference to fancy apartments developed from its application to a structure .
The coupling between pentlandite dissolution and violarite precipitation is controlled by local solution chemistry as well as the epitaxial nucleation of violarite onto the pentlandite substrate. The latter was confirmed by electron backscatter diffraction (EBSD) analysis that pentlandite and violarite share a common crystallographic orientation.
The aggregate used to produce the concrete housing foundations is an anorthositic gabbro (field identification term), more precisely a norite or a hypersthene's gabbro, containing various proportions of sulfide minerals including pyrite, pyrrhotite, pentlandite ((Fe,Ni) 9 S 8) and chalcopyrite (CuFeS 2).
Abstract The use of pyrrhotitecontaining aggregate in concrete has led to the premature deterioration of building foundations in Connecticut (). Pyrrhotite is a highly reactive ironsulfide mineral that can initiate internal sulfate attack in concrete structures, because it serves as a source of sulfate ions for secondary minerals.

During condensation from a cooling nebular gas, troilite (FeS), rather than pentlandite, is the stable sulfide phase that forms at temperatures <710 K, by reaction of Fe metal with H 2 S, although pentlandite, instead of troilite, can form during this reaction if the metal is Nibearing .

1. A structure occupying usually less than half the roof area of a flatroofed building, and used: (a) to house equipment for elevator, ventilation or air conditioning, or other mechanical or electrical systems serving the building, or (b) to house one or more apartments, access to which is gained by a stair or stairs, or a separate elevator but usually not by the building's main elevators.
Copper is easily worked and relatively cheap so it is used for the bulk of the wiring that connects our society's electrical systems. Although this is currently its most important contribution, copper has also been in demand for uses ranging from coinage to building decorations.
