TL;DR: In this article, it has been realized that dendritic macromolecules can exhibit similar properties, though on a more modest scale, and they have been used as model systems in light-emitting diodes, signal amplifiers, fluorescent sensors, frequency converters, and other photonic devices.

TL;DR: In this paper, amino-functionalized SBA-15 silicas with uniform parameters were used for removing heavy metal ions from waste water; the thiolated adsorbent exhibited a higher complexity affinity for Hg2+, while the other metal ions (Cu2+, Zn2+, Cr3+ and Ni2+) showed exceptional binding ability with its aminated analogue.

TL;DR: In this article, the authors highlight the advantages of employing fullerene as a viable electron accepting building block in novel donor/acceptor systems and present different strategies that aim to improve charge separation in ful lerene containing systems.

TL;DR: The reaction between solvent free gallium and potassium in toluene has been shown to be analogous to a singlet carbene carbon as mentioned in this paper, which features a V-shaped, two-coordinate, six-electron gallium center.

TL;DR: In this article, the AIM approach, by analyzing the topological properties of the charge density with the determination of critical points, provides another way of looking for bonds, as discussed in several examples.

TL;DR: In this paper, high ordered, hydrothermally stable, caged cubic cubic mesoporous structures with unusually large porosity (120 A) have been synthesized by using hydrophobic poly(butylene oxide) containing triblock PEO copolymer as a structure-directing agent.
