TL;DR: A task-specific ionic liquid, [bmIm]OH, has been introduced as a catalyst and as a reaction medium in Michael addition, which drives the reaction of open-chain 1,3-dicarbonyl compounds with alpha,beta-unsaturated esters and nitriles toward bis-addition to produce exclusively bis-adducts in one stroke.

TL;DR: It is shown that for generic nonintegrable interacting systems, local observables become independent of the initial state entirely.
Abstract: When a closed quantum system is driven periodically with period $T$, it approaches a periodic state synchronized with the drive in which any local observable measured stroboscopically approaches a steady value. For integrable systems, the resulting behavior is captured by a periodic version of a generalized Gibbs ensemble. By contrast, here we show that for generic nonintegrable interacting systems, local observables become independent of the initial state entirely. Essentially, this happens because Floquet eigenstates of the driven system at quasienergy ${\ensuremath{\omega}}_{\ensuremath{\alpha}}$ consist of a mixture of the exponentially many eigenstates of the undriven Hamiltonian, which are thus drawn from the entire extensive undriven spectrum. This is a form of equilibration which depends only on the Hilbert space of the undriven system and not on any details of its Hamiltonian.

TL;DR: Metal-semiconductor hybrid nanostructures are found to be very promising for photonic applications due to their exciton-plasmon interactions and the significance of porphyrin-based nanostructure for potential light-harvesting systems is discussed.
Abstract: Recent advances and the current status of challenging light-harvesting nanomaterials, such as semiconducting quantum dots (QDs), metal nanoparticles, semiconductor–metal heterostructures, π-conjugated semiconductor nanoparticles, organic–inorganic heterostructures, and porphyrin-based nanostructures, have been highlighted in this review. The significance of size-, shape-, and composition-dependent exciton decay dynamics and photoinduced energy transfer of QDs is addressed. A fundamental knowledge of these photophysical processes is crucial for the development of efficient light-harvesting systems, like photocatalytic and photovoltaic ones. Again, we have pointed out the impact of the metal-nanoparticle-based surface energy transfer process for developing light-harvesting systems. On the other hand, metal–semiconductor hybrid nanostructures are found to be very promising for photonic applications due to their exciton–plasmon interactions. Potential light-harvesting systems based on dye-doped π-conjugated s...
