cobalt ferrite (cofe2o4) nanorods were synthesized by iron chloride (fecl3.6h2o) and cobalt sulfate hexahydrate (coso4.7h2o) as precursor in the presence of ethylene glycol agent and poly vinyl pyrrolidone (pvp) surfactant. the samples were characterized to identify the physical properties. xrd pattern of cobalt ferrite samples showed the structure of body center cubic (bcc) structure. the diam...

Abstract Microemulsion (ME) is widely used in food, pharmaceuticals, and medical applications. In the formulation of MEs, a substantial amount surfactant needed to stabilize lipo-hydrophilic interface, which may have adverse effects on biological cells. Cellulose its derivatives been extensively utilized as solid emulsifying agents, known pickering are added improve stability emulsions. this st...

Hard magnetic nanoparticles based on the Sm(2)Co(17) and SmCo(5) systems have been successfully produced using a surfactant-assisted ball milling technique. A size-selection process has been developed to obtain nanoparticles of different sizes with narrow size distribution. Significant room-temperature coercivity up to 3.1 kOe has been achieved with the Sm(2)Co(17)-based nanoparticles of an ave...

The rate of aquation of [Co(NH3)s (DMSO)] Bra was measured in solutions containing the surfactant cetyltrimethylammonium bromide (CTAB) over the concentration range 9.55 x 10-4 mol dm-3 to 0.450 mol dm-3• This large change in CTAB concentration affected the rate very little and no significant amounts of Co(NH3)sBr+ were formed .. It was concluded that, if Brcounterions were concentrated in the ...

CO confinement strategy for ultrathin Rh nanosheets: CO is introduced as a confining agent to regulate the anisotropic growth of unique 2D structure. The single-crystalline Rh nanosheets have a thickness of three to five atomic layers and tunable edge length ranging from 500 to 1300 nm. By understanding the formation mechanism, surface-clean Rh nanosheets are also prepared and display better ca...

Saturated sand-packed column experiments were conducted to investigate the influence of physicochemical factors on the transport and retention of surfactant stabilized silver nanoparticles (AgNPs). The normalized concentration in breakthrough curves (BTCs) of AgNPs increased with a decrease in solution ionic strength (IS), and an increase in water velocity, sand grain size, and input concentrat...

One of the common chronic inflammatory skin diseases is Acne Vulgaris that affects up to 80% of a teen-age population. The progress of acne lesions is due to colonization of Propionibacterium acnes (P .acnes) in hair follicles. Treatment of acne includes topical or systemic therapy or combination therapy, with a tendency to perform topical therapy in mild to moderate acne. Nanoemulsions, small ...
