The application of Fe–TiO2 photocatalysis using sol–gel method by hot–dipping technique was investigated. Then, the influences of fabrication parameters, molar ratios of Fe to TiO2, the sol temperature, poly ethylene glycol (PEG) content and the number of dipping cycles on the photocatalytic activity in visible light region were mainly studied. The experimental results revealed the sample with ...

Recent observations [1, 2] around the critical point showed that the critical exponents differed drastically for pure hydrogel systems depending on monomer concentration. To investigate hydrogels, the sol-gel phase transition during free radical crosslinking copolymerization the various amounts of acrylamide (AAm) and N-isopropylacrylamide (NIPA) mixtures was studied by using steady state fluor...

In this article we introduce and compare three techniques for low-cost and rapid bonding of stereolithographically structured epoxy components to polydimethylsiloxane (PDMS). In short, we first create a polysiloxane layer on the epoxy surface via silane surface coupling and polymerization. Afterwards, the modified epoxy surface can be bonded to a PDMS component at room temperature using a handh...
