An analysis on the magnetic fluid seal capacity

New shells for magnetic nanoparticles based on polypyrrole functionalized with α-amino acids

“…Magnetic nanoparticles (MN) have recently gained broad interest in various fields, such as medicine, [1][2][3][4] biomedicine, [5][6][7][8][9][10] in the construction of loudspeakers, 11,12 as sealing materials [13][14][15][16][17][18] and in sink float separation. [19][20][21][22] For many medical and biomedical applications it is essential to functionalize their surface.…”

Ferrofluid Seals

“…However, they are more commonly used as squeeze films in seals and bearings for rotating devices. Tarapov carried out some pioneering work regarding the ferrofluid lubrication in the case of a plain journal submitted to a non-uniform magnetic field (6) but more recent works show and discuss the recent trends in such a use (7)- (13). Moreover, ferrofluid dynamic bearings have been regularly studied and their static and dynamic characteristics have been described theoretically (14)- (21).…”

Mechanical properties of ferrofluid applications: Centering effect and capacity of a seal

“…Studies on ferrofluids deal either with their chemical and physical properties [3] [4] or their mechanical behavior [5] [6]. Ferrofluids have various engineering applications [7] and the authors are interested in the design of ironless loudspeakers [8]- [12].…”
