Functional polymeric micro/nanofibers have gained considerable interest as promising materials for the structures that are potentially beneficial in lot of application areas as they possess excellent characteristics such as large surface-area-to-volume ratio, incredibly small pore dimensions etc. Microfluidic developments have currently shown a huge amount of opportunities as revolutionary approaches to create microfiber. By carefully regulating the flow and reaction kinetics in microchannel chip, microfluidic-spinning technology can be applied to generate fibers with tailored characteristics and polymorphic structures. However, this paper features the basic mechanism of micro-fiber production by microfluidic spinning Technology (MST) as well as the principle of Elcectro-Microfluidic Spinning Technology (EMST). Besides, core-shell fiber production by MST is also described in brief. Finally, the advantageous features, application areas and challenges of MST are reviewed briefly in this paper.

Future innovations of electronics are bounded by the availability of effective cooling methods to remove heat that is generated. Micro- and minichannels, acting as heat exchangers, are effective in removing heat from small surfaces because of their large surface area to volume ratio [1]. Both micro pin finned structures [2,3] and nanofluids [4–6] have proven to provide significant enhancement in thermal performance in minichannels.

Reverse micro emulsion method showed some advantages in the preparation of the catalyst MnBaAl11O19-δ with large surface area and high activity, when compared with sol-gel method or co-precipitation method. The influences of water content in reverse micro emulsion on nanostructure catalyst MnBaAl11O19-δ were discussed in this paper. The catalyst MnBaAl11O19-δ was prepared by reverse microemulsion method with a system consisted of 55% of n-heptane, 15% of emulsifier OP-10, 15% of 1-octanol and 15% of water (volume ratio). It resulted in the catalyst a length of 10-30nm plated-like phase and large surface area of 106 m2/g. The catalyst was applied in dimethyl ether combustion and it showed high activity with T10% at 160 °C and T90% at 300 °C. The recycle reverse micro emulsion was reused to prepare the catalyst MnBaAl11O19-δ. The catalyst MnBaAl11O19-δ prepared with that, still showed large surface area of 65m2/g and high activity with T10% at 170 °C and T90% at 320 °C in dimethyl ether catalytic combustion.
