Hollow platinum-gold and palladium-gold nanoparticles: synthesis and characterization of composition-structure relationship

Synthesis, Characterization, and SERS Functionalization of Hollow Gold Nanoparticles

Hollow gold nanoparticles formed by galvanic replacement reactions have been extensively studied because their increased surface area and tunable optical properties have applications in catalysis, drug delivery, and photothermal cancer therapies. In this study, hollow gold nanoparticles (size 30-40 nm) were synthesized by transmetallation of tyrosinereduced sacrificial solid silver nanospheres....

Green Synthesis of Gold, Platinum and Palladium Nanoparticles by Lignin and Hemicellulose

Nowadays, noble metal nanoparticles (NPs) are at a leading edge of the rapidly developing field of nanomaterials [1-3]. Preparation of noble metal NPs, such as platinum, gold and palladium, have been studied intensively based on their wide usefulness in magnetic, electronic, catalytic and mechanic technologies [4,5] Various methods have been developed for their preparation, including citrate re...

Synthesis and Characterization of Gold Nanoparticles

Synthesis and characterization of Janus gold nanoparticles.

A IO N Ligand molecules on monolayer-protected gold nanoparticles (NPs) determine the majority of their surface properties. It has been established that when a binary mixture of dislike ligands forms a self-assembled monolayer either on fl at surfaces [ 1 ] or on a NP, [ 2 ] separation into distinct domains occurs. For gold NPs between ∼ 3 and ∼ 8 nm in diameter, stripe-like domains form. [ 2b ...

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
