Extracellular vesicles (EVs) are present in blood at much lower concentrations (5-6 orders of magnitude) compared to lipoprotein particles (LP). Because LP and EV overlap size density, isolating high-purity EVs is a significant challenge. While the current two-step sequential isolation process using size-expression chromatography (SEC) followed by density gradient (DG) achieves high purity, time-consuming ultracentrifugation (UC) step DG hinders workflow efficiency. This paper introduces an...
Sintered Ni doped Fe/sub 3/O/sub 4/ ferrites were prepared by mixing powder with NiO and compressing into pellet, then sintering in argon atmosphere. The contents of the sintered samples between 0 at.% 5.08 at.%. effects content, temperature time on magnetoresistance (MR) microstructure investigated. X-ray diffraction chemical titration analysis Fe/sup 2+/ 3+/ ions indicate that nonstoichiometric phases 4+X/ NiFe/sub 2/O/sub 4-Y/ co-existed sample. optimum temperature, at which maximum MR...
Fe/sub 3/O/sub 4/ powder was mixed with MgO and then sintered in an atmosphere of argon at various temperatures for 3 h to form Mg-doped ferrites. The effects the sintering temperature, microstructure, Mg content on magnetoresistance ferrites were investigated. X-ray diffraction chemical titration analysis Fe/sup 2+/ 3+/ ions indicate that nonstoichiometric phases 4+X/ MgFe/sub 2/O/sub 4-x/ coexisted sample. temperature dependence resistivity examined.

50 nm Ag1−xSbx (x=10.8–25.5) thin films were prepared by magnetron sputtering. Thermal analysis shows that the phase change occurs around 250°C. The optical property show as-deposited Ag80.9Sb19.1 have high reflectivity of about 62%–73%. After heat treatment at 300°C, contrast film is 12.5%–17% for wavelengths between 400 and 800nm. Dynamic test using as memory layer write once disk, a carrier-to-noise ratio 45dB can be achieved λ=657nm, numerical aperture 0.65, linear velocity 3.5m∕s.
The Fe3O4 powder was mixed with Co-ferrite then sintering in argon atmosphere at temperatures between 1000 °C and 1250 for 4 hours. Effects of the temperature, microstructure content on magnetoresistance sintered ferrite mixture were investigated. 0 mol% 32.28 mol%. It found that Co ions dispersed uniformly all samples by analysis element mapping scanning electron microscopy. maximum ratio room temperature is about 7.45% when 4.26 1200 °C.
