Organic Phase Syntheses of Magnetic Nanoparticles and Their Applications

Effect of precursor concentration on size evolution of iron oxide nanoparticles

Changing the precursor concentration to tune the iron-oxide nanoparticle size alters the surfactant/precursor ratio and leads to the observation of two size regimes.

Poly(benzofuran-co-arylacetic acid) – a new type of highly functionalized polymers

A new type of polymer containing a number of functional groups with orthogonal reactivity, allowing linkage to several functionalities.

A simple and low-cost route to recycle rare earth elements (La, Ce) from aqueous solution using magnetic nanoparticles of CoxMn1−xFe2O4 (x = 0.2 and 0.8): synthesis, isotherms, kinetics, thermodynamics and desorption

Magnetic nanoparticles of Co_xMn_1−xFe₂O₄ with a large surface area have been developed for REE cations adsorption.

Feasibility of USPIOs for T1-weighted MR molecular imaging of tumor receptors

USPIOs having a superior T₁ contrast effect could only be used for T₂-weighted, but not for T₁-weighted MR tumor receptor imaging.

Multicomponent synthesis of new curcumin-based pyrano[2,3-d]pyrimidine derivatives using a nano-magnetic solid acid catalyst

An novel nano-magnetic solid acid catalyst was used for the efficient synthesis of new curcumin-based pyrano[2,3-d]pyrimidine derivatives via a multicomponent reaction under mild conditions.

Synthesis of gadolinium oxide nanodisks and gadolinium doped iron oxide nanoparticles for MR contrast agents

Herein, we report the synthesis of differently sized gadolinium oxide nanodisks and gadolinium doped iron oxide spherical and cubic nanoparticles through the thermal decomposition of an oleate precursor.

Gram-scale synthesis of superparamagnetic Fe3O4 nanocrystal clusters with long-term charge stability for highly stable magnetically responsive photonic crystals

We report the gram-scale hydrothermal synthesis of superparamagnetic Fe₃O₄ CNCs with superior long-term charge stability, which are suitable building blocks for magnetically responsive photonic crystals (MRPCs) with widely, rapidly and reversibly tunable diffractions across the visible and near IR range, as well as long-term stability of photonic performances. The scalable synthesis of Fe₃O₄ CNCs with excellent long-term colloidal stability will facilitate their wide application in photonics, biomedicine, catalysis and other areas.

The role of water in the synthesis of indium nanoparticles

We report the water-assisted synthesis of indium nanoparticles (In NPs). We found that a precise amount of water was necessary to allow the formation of the desired 7 nm In NPs: the oxidation of the In surface by water inhibits the growth of NPs as well as subsequent reactivity with white phosphorus (P₄). A novel surface activation method based on the use of organosilanes is presented.
