Nanolimes have been commercially available for over a decade as a remineralization agent for natural stone to combat deterioration. While they have been applied successfully and studied extensively, their penetration abilities in different materials have not yet been readily quantifiable in situ and in real time. Using two transparent pore-imitatin...
Cultural heritage made from carbonatic rocks suffers a multitude of deteriorating processes, including acidic influences by environmental pollution. Prominent examples include calcitic materials such as limestone and marbles – often used in architecture and sculpting.
Even among calcitic stone there are significant differences in porosity, wetting...
The investigation of mineralization and demineralization processes is important for the understanding of many phenomena in daily life. Many crystalline materials are exposed to decay processes, resulting in lesions, cracks, and cavities. Historical artifacts, for example, often composed of calcium carbonate (CaCO3), are damaged by exposure to acid...
Heterobimetallic 1,4-divinylphenylene- and 1,8-divinylanthracene-bridged ruthenium/osmium complexes 1-RuOs and 2-RuOs were prepared via stepwise hydroruthenation of the parent dialkynes with first the ruthenium and then the osmium hydride complexes HM(CO)Cl(PiPr3)2. They are compared with their homobimetallic diruthenium and diosmium analogs with r...
The Diels-Alder (DA) reactions of pentacene (PT), 6,13-bis(2-trimethylsilylethynyl)pentacene (TMS-PT), bistetracene (BT), and 8,17-bis(2-trimethylsilylethynyl)bistetracene (TMS-BT) with the [6,6] double bond of [60]fullerene have been investigated by density functional theory (DFT) calculations. Reaction barriers and free energies have been obtaine...
We report the synthesis and characterization of "bistetracene," an unconventional, linearly extended conjugated core with eight fused rings. The annellation mode of the system allows for increased stability of the conjugated system relative to linear analogues due to the increased number of Clar aromatic sextets. By attaching the appropriate solubi...
