Functional gel particles produced through the incorporation of an inorganic material are used in a wide range of applications ranging from cosmetics to optics and biotechnology. Such particles with uniform morphologies are desirable because of their consistent and reproducible behavior. Particularly, microparticles consisting of magnetic materials encapsulated in a polymer matrix are of great i...

Background & Aims: Magnetically molecularly imprinted polymers (MMIPs) are assumed as kind of sorbent polymers ‎which can separate or determine bioactive compounds from environment fast and specifically.  ‎Magnetic properties, stability at various conditions (temperature , ionic strength and pH) and selective ‎function are among the advantages of these polymers in determin...

An easy assembling-disassembling co-axial capillaries microfluidic device was built up for the production of double droplets. Uniform polymer core-polymer shell particles were synthesized by polymerizing the two immiscible monomer phases composing the double droplet. Thus poly(acrylamide) core-poly(tri(propylene glycol) diacrylate) shell particles with controlled core diameter and shell thickne...

synthesis of bafe12o19 magnetic nano particles via precipitation in different ph conditions have been reported. the certain molar ratio of fe/ba = 12 selected and sodium hydroxide was used as a precipitant agent. x-ray diffraction (xrd), scanning electron microscopy (sem) and vibrating sample magnetometer (vsm) were used to consider the structural, morphological and magnetic properties of bariu...

The phase behaviour of a single large semiflexible polymer immersed in a suspension of spherical particles is studied. All interactions are simple excluded volume interactions and the diameter of the spherical particles is an order of magnitude larger than the diameter of the polymer. The spherical particles induce a quite long ranged depletion attraction between the segments of the polymer and...

Yittrium iron garnet, Y3Fe5O12 (YIG), is a material used widely in electronic devices for the microwave region as well as the magnetic bubble domain-type memories. Yittrium iron garnet (Y3Fe5O12) was produced by mechanochemical synthesis from Y2O3 and Fe2O3 with particle size of around 150 nm. PMMA/YIG composite films were prepared by solution casting method at diffferent concentration (i.e. 10...

Environmentally responsive poly(N-isopropylacrylamide) brushes were grafted from the surface of polymer particles or flat surfaces in order to generate reversible hydrophilic and hydrophobic surfaces. The use of atom transfer radical polymerization was demonstrated for the grafting of polymer brushes as it allows efficient control on the amount of grafted polymer. The polymer particles were gen...

polybutadiene nanoparticles were synthesized via batch emulsion polymerization of butadiene in the presence of potassium persulfate, disproportionate rosinate potassium cation and t-dodecyl mercaptane as initiator, emulsifier and chain transfer agent, respectively. polymerization reaction was performed at different temperatures (60, 70 and 80 °c). conversion was measured at the various time int...

Amitriptyline hydrochloride is a highly permeable active pharmaceutical ingredient (API). The function of these drugs is to block the reuptake of the neurotransmitters, norepinephrine and serotonin in the central nervous system. The nano-sized Amitriptyline (AT) imprinted polymer particles were synthesized successfully. The nanoparticles were characterized by Fourier transform infrared spectros...
