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...

We consider a simple Stackelberg model with demand uncertainty only for the first mover in order to compare the advantages of leadership and flexibility, and use an example to provide some discussion about the endogenous order of moves in the presence of demand uncertainty. We find that only...

Microalgae have been considered as a promising biomass for biofuel production, but freshwater resource consumption during the scaled-up cultivation are still a challenge. Obtaining robust marine strains capable of producing triacylglycerols and high value-added metabolites are critical for...

Ronen Avraham explains why he thinks Jonathan Carmel is taking a good thing too far by proposing to take the tort lawyers out of the system altogether.
