Cetyltrimethylammonium Bromide Assisted Preparation and Characterization of Pd Nanoparticles with Spherical, Worm-Like, and Network-Like Morphologies

Shape-Controlled Paclitaxel Nanoparticles with Multiple Morphologies: Rod-Shaped, Worm-Like, Spherical, and Fingerprint-Like

Although many nanocarriers have been developed to encapsulate paclitaxel (PTX), the drug loading and circulation time in vivo always are not ideal because of its rigid "brickdust" molecular structure. People usually concentrate their attention on the spherical nanocarriers, here paclitaxel nanoparticles with different geometries were established through the chemical modification of PTX, nanopre...

preparation of silicious mesoporous spherical and rod- like mcm-41 using cetyltrimethylammonium bromide as the structure directing agent

mcm-41 is one of the groups of mesoporous materials that have wide applications as adsorbents, ion exchangers and catalyst supports. in this work spherical and rod-like mcm-41s were synthesized in homogeneous and heterogeneous reaction media, respectively. for synthesis of these materials the cationic surfactant cetyltrimethylammonium bromide (ctmabr) was used as template and tetraethylorthosil...

Preparation and characterization of spindle-like Fe3O4 mesoporous nanoparticles

Magnetic spindle-like Fe3O4 mesoporous nanoparticles with a length of 200 nm and diameter of 60 nm were successfully synthesized by reducing the spindle-like α-Fe2O3 NPs which were prepared by forced hydrolysis method. The obtained samples were characterized by transmission electron microscopy, powder X-ray diffraction, attenuated total reflection fourier transform infrared spectroscopy, field ...

preparation and characterization of catanionic vesicles composed of cetyltrimethylammonium bromide, sodium lauryl sulfate and cholesterol

The Role of Ethanol, Methyltriphenylphosphonium Bromide and Cetyltrimethylammonium Bromide as Directing Agents in Hydrothermal Synthesis of Aluminosilicate Molecular Sieve (ZSM-5) and Its Morphologies

Zeolite ZSM-5 presents a great source of interest in catalysis because of its shape selective properties. The absence of a relationship between the template size and shape of the structure generated during the synthesis of zeolites is illustrated by the case of ZSM-5. In this study, we have investigated the role of ethanol, methyltriphenylphosphonium bromide (MTPBr) and cetyltrimethylammonium b...
