Anti-Stokes Raman spectroscopy as a method to identify metallic and mixed metallic/semiconducting configurations of multi-walled carbon nanotubes

SERS studies were performed on films of two families of multi-wall carbon nanotubes (MWCNTs) under an excitation light of 514.5 nm and 647.1 nm. These included Aldrich-MWCNTs, which alternate semiconducting and metallic tubes and M-MWCNTs that contain only ...

Mechanism of oxygen reduction by metallocenes near liquid|liquid interfaces

Hubert Girault, Pekka Eero Peljo, Thomas James Stockmann, Haiqiang Deng

The mechanism of the oxygen reduction reaction (ORR) at a liquid|liquid interface, employing ferrocene (Fc) derivatives – such as decamethylferrocene (DMFc) – as a lipophilic electron donor along with sulfuric acid as an aqueous proton source, was elucidat ...

Engineering of Ru(II) dyes for interfacial and light-harvesting optimization

Michael Graetzel, Mohammad Khaja Nazeeruddin, Filippo de Angelis, Kuan-Lin Wu, Gabriele Marotta

A new Ru(II) dye, Ru(L1)(L2) (NCS)(2), L1 = (4-(5-hexylthiophen-2-yl)-4'(4-carboxyl-phenyl 2,2'-bipyridine) and L2 = (4-4'-dicarboxy-2,2'- bipyridine), labelled MC112, based on a dissymmetric bipyridine ligand for improved interfacial and optical propertie ...

Reversible, zinc-selective chemical reactions that enable imaging biological Zn2+ at long wavelengths

Pablo Rivera Fuentes

Fluorescent sensors are valuable tools for investigating the biochem. of metal cations, notably calcium and zinc. Most probes rely on quenching of photoinduced electron transfer as a fluorescence turn-on mechanism. The information that can be obtained from ...

Photosynthetic reaction centre/carbon nanotube bundle composites

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi

Since their discovery, carbon nanotubes (CNTs) have attracted intense attention to broad range of potential applications. In contrast to the 1D isolated single-walled carbon nanotubes (SWCNT), 2D films or bundles made of thousands of tubes have been introd ...

The ultrastructure of Chlorobaculum tepidum revealed by cryo-electron tomography

Henning Paul-Julius Stahlberg

Chlorobaculum (Cba) tepidum is a green sulfur bacterium that oxidizes sulfide, elemental sulfur, and thiosulfate for photosynthetic growth. As other anoxygenic green photosynthetic bacteria, Cba tepidum synthesizes bacteriochlorophylls for the assembly of ...

Quadrupolar Benzobisthiazole-Cored Arylamines as Highly Efficient Two-Photon Absorbing Fluorophores

Vladislav Semak

A computer-aided design of novel D-pi-A-pi-D styrylamines containing five isomeric benzobisthiazole moieties as the electron-accepting core has revealed the linear centrosymmetric benzo[1,2-d:4,5-d']bisthiazole as the most promising building block for engi ...

Inhibition of Sepiapterin Reductase through Formation of a Ternary Complex with Sulfasalazine or other Sulfa Drugs and NADP+

Miriam Grønlund Pedersen

The mechanism of action of sulfasalazine, an anti-inflammatory drug used against inflammatory bowel diseases and rheumatoid arthritis is, despite its medical importance, still not well understood. Recently, it was shown that sulfasalazine and its metabolit ...

Plastidic type I signal peptidase 1 is a redox-dependent thylakoidal processing peptidase

Jieping Zhu

Thylakoids are the photosynthetic membranes in chloroplasts and cyanobacteria. The aqueous phase inside the thylakoid known as the thylakoid lumen plays an essential role in the photosynthetic electron transport. The presence and significance of thiol-disu ...

Plant nanobionics approach to augment photosynthesis and biochemical sensing

Ardemis Anoush Boghossian

The interface between plant organelles and non-biological nanostructures has the potential to impart organelles with new and enhanced functions. Here, we show that single-walled carbon nanotubes (SWNTs) passively transport and irreversibly localize within ...
