Patent number: 9076579Abstract: A permanent magnet is fabricated such that it has a magnetically hard core surrounded by a thin magnetically soft shell. The magnetically hard core provides a relatively high intrinsic coercivity (Hci), and the magnetically soft shell provides a relatively high magnetic flux density (B). Due to magnetic exchange coupling between the core and shell, a relatively high maximum energy product (BH)max is achievable over a wide temperature range, including temperatures above 150° C. Further, such effects can be achieved without using rare-earth metals or precious metals helping to keep the manufacturing costs of the magnet low. To allow sufficient exchange magnetic coupling between the core and shell, the width of the shell is less than about 40 nanometers, and the overall dimensions are controlled such that the width of the shell is less than two times the Bloch domain wall thickness of the core.Type: GrantFiled: November 15, 2011Date of Patent: July 7, 2015Assignee: The Board of Trustees of the University of Alabama for and on the behalf of the University of AlabamaInventors: Yang-Ki Hong, Seok Bae

Publication number: 20150144834Abstract: A composition comprising a fluid, and a material dispersed in the fluid, the material made up of particles having a complex three dimensional surface area such as a sharp blade-like surface, the particles having an aspect ratio larger than 0.7 for promoting kinetic boundary layer mixing in a non-linear-viscosity zone. The composition may further include an additive dispersed in the fluid. The fluid may be a thermopolymer material. A method of extruding the fluid includes feeding the fluid into an extruder, feeding additives into the extruder, feeding a material into the extruder, passing the material through a mixing zone in the extruder to disperse the material within the fluid wherein the material migrates to a boundary layer of the fluid to promote kinetic mixing of the additives within the fluid, the kinetic mixing taking place in a non-linear viscosity zone.Type: ApplicationFiled: November 20, 2014Publication date: May 28, 2015Inventor: WILLIAM L. JOHNSON, SR.

Publication number: 20150147362Abstract: The present disclosure relates to polymeric siloxane coated zinc oxide powders having a mean particle size number distribution (D50) ranging from about 300 nm to about 600 nm and their use in sunscreen compositions. The relatively high surface area (in relation to particles of <100 nm) avoids agglomeration resulting in ease of formulation and high dispersal of the particles which tends toward less light scatter and hence better transparency in formulations. Furthermore, the combination of the particular particle size number distribution (D50) of zinc oxide ranging as above with bis(resorcinyl)triazine UV absorbers shows unexpected increased UV-A absorbance (320 to 400 nm) in comparison to the zinc oxide and bis resorcinyl triazine UV absorbers on their own at the same concentration.Type: ApplicationFiled: May 14, 2013Publication date: May 28, 2015Applicant: BASF SEInventors: Tatiana Drovetskaya, Marc N.G.
