Rapid and efficient clean-up of viscous crude oil spills is still a global challenge due to its high viscous and poor flowability at room temperature. The hydrophobic/oleophilic absorbents with three-dimensional porous structure have been considered as a promising candidate to handle oil spills....

Efficient ternary organic photovoltaics (OPVs) are fabricated with two polymer materials, PTQ10 and PTB7-Th, as donors and Y6 as an acceptor. The lowest unoccupied molecular orbital (LUMO) energy levels of PTB7-Th are deeper than those of PTQ10, and a cascade of LUMO energy levels is formed...

For the hybrid magnetically suspended flywheel (MSFW) rotor with two degrees of freedom (DOF) radial active magnetic bearing (AMB) and three DOFs axial AMB, the vibration analysis, measurement and balancing are conducted to mitigate the influences caused by unbalance terms in this article....
