That is, a ferrofluid contains primarily nanoparticles, while an MR fluid contains primarily micrometre-scale particles. The particles in a ferrofluid are suspended by Brownian motion and generally will not settle under normal conditions, while particles in an MR fluid are too heavy to be suspended by Brownian motion. Particles in an MR fluid ...
Ferrofluidic seals rely on the general principle of ferrofluids - fluids that display magnetic attraction.Following research on ferrofluids during the 1960s, the ferrofluidic seal was first patented in 1971 by R.E. Rosensweig (USP 3,620,584), who subsequently founded Ferrofluidics Corporation with R. Moskowitz.

The global market for chemicals from fluorine was about US$16 billion per year as of 2006. [1] The industry was predicted to reach 2.6 million metric tons per year by 2015. [2] The largest market is the United States. Western Europe is the second largest. Asia Pacific is the fastest growing region of production. [2]
Benguet Corporation is a diversified Philippine business enterprise. Founded in 1903 as the Benguet Consolidated Mining Company [ 2 ] by three American G.I.s following the Philippine-American War , [ 1 ] it is the oldest mining company in the country.
Ferrofluid deformable mirror. A ferrofluid mirror is controlled by a number of actuators, often arranged in a hexagonal array. [3] [4] Pure ferrofluids have low reflectivity, so they must be coated with a reflective layer. Water-based ferrofluids hold the reflective layer effectively, but water evaporates so quickly that the mirror could ...
Also, in 2008, the first large-scale silicon wafer-slicing plant was inaugurated in the Philippines – First Philec Solar Corp. This subsidiary, a joint venture between First Holdings and the Sunpower of the United States, aims to develop the solar energy industry in the Philippines and to compete with companies providing wafer-slicing ...
