Modeling and analysis of an electrorheological flow behavior containing semiconducting graphene oxide/polyaniline composite particles

The flow behavior of electrorheological suspensions containing graphene oxide/polyaniline composite particles was reanalyzed using a model we proposed recently. The shear stress data obtained experimentally from an lectrorheological fluid revealed that the structural reformation of the aligned fibers depended on the shear rate, in good agreement with the model. The static yield stress was depended…

Highly Efficient Vacuum-Processed Organic Solar Cells Containing Thieno[3,2‑b] thiophene-thiazole

Two novel electron-donor molecules based on donor−π-conjugated linker–acceptor structure with compact packing and intramolecular charge-transfer characteristics were synthesized for the preparation of efficient organic solar cells. The donor molecules featuring an electron-rich triphenyl amine as the electron-donor unit, dicyanovinylene as the acceptor unit, and π-conjugated linkers of thienothiophene, thiophene, and thiazole units were synthesized. The…

Core-Shell Structured Polystyrene Coated Carbonyl Iron Microspheres and their Magnetorheology

Soft magnetic carbonyl iron (CI) microparticle, possessing high magnetic saturation with less magnetic hysteresis, was mostly applied as an active material in magnetorheological (MR) fluids. However, pure CI suspension is known to have poor dispersion stability in the MR fluid system. To overcome this problem, we fabricated polystyrene (PS)-coated CI particles through a simple coating…
