In general terms, submicron particles can be prepared either by disintegration of larger entities, or by synthesis from small building blocks such as atoms, ions or molecules. By comparison to disintegration techniques, the latter approach provides efficient access to particles down to the nanometer size regime; and it can allow for the controlled synthesis of particles in terms of size, size d...

this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....

this study describes the synthesis of molecularly imprinted polymers (mips) by using an anti-che ops, namely dursban, as a template. non-covalent bulk polymerization was successfully applied to synthesis different imprinted and non-imprinted polymers with maa, mma, aa, and 4-vpy as monomer in selected porogens (chloroform, toluene, and acetonitrile). in order to evaluate the template binding of...

Objective(s): Researchers have intended to reformulate drugs so that they may be more safely used in human body. Polymer science and nanotechnology have great roles in this field. The aim of this paper is to introduce an efficient drug delivery vehicle which can perform both targeted and controlled antibiotic release using magnetic nanoparticles grafted pH-responsive polymer.<s...

Synthesis of well-defined homodimeric protein-polymer conjugates using RAFT polymerization is described.

Antifreeze (glyco) proteins AF(G)Ps are potent ice recrystallization inhibitors, which is a desirable property to enhance cryopreservation of donor tissue/cells. Here we present the rational synthesis of a new, biomimetic, ice-recrystallization inhibiting polymer derived from a cheap commodity polymer, based on an ampholyte structure. The polymer is used to enhance the cryopreservation of red b...

A novel one-step synthetic route, the double in situ approach, is used to produce both TiO(2) nanoparticles and polymer (PET), and simultaneously forming a nanocomposite with multi-functionality. The method uses the release of water during esterification to hydrolyze titanium (IV) butoxide (Ti(OBu)(4)) forming nano-TiO(2) in the polymerization vessel. This new approach is of general significanc...

Conventional mechanical pumps based on centrifugal or axial turbomachinery are not suitable for micro and nano scales where the Reynolds numbers are usually small. Centrifugal and inertial forces are negligible, and viscous forces dominate the flow field in this length scale (an excellent review can be found on the physics of fluid flow at microscale in [1]). A microfluidic rotary pump, which i...
