Models for the Active Site in [FeFe] Hydrogenase with Iron-Bound Ligands Derived from Bis-, Tris-, and Tetrakis(mercaptomethyl)silanes

A series of multifunctional (mercaptomethyl)silanes of the general formula type RnSi(CH2SH)4-n (n = 0-2; R = organyl) was synthesized, starting from the corresponding (chloromethyl)silanes. They were used...

Complete modal decomposition for optical fibers using CGH-based correlation filters

The description of optical fields in terms of their eigenmodes is an intuitive approach for beam characterization. However, there is a lack of unambiguous, pure experimental methods in contrast to numerical...

Arrays of Regenerated Fiber Bragg Gratings in Non-Hydrogen-Loaded Photosensitive Fibers for High-Temperature Sensor Networks

We report about the possibility of using regenerated fiber Bragg gratings generated in photosensitive fibers without applying hydrogen loading for high temperature sensor networks. We use a thermally induced...

Photophysics of an Intramolecular Hydrogen-Evolving Ru-Pd Photocatalyst

Photoinduced electron-transfer processes within a precatalyst for intramolecular hydrogen evolution [(tbbpy)2Ru(tpphz)PdCl2]2+ (RuPd; tbbpy=4,4′-di-tert-butyl-2,2′-bipyridine, tpphz=tetrapyrido[3,2-a:2′,3′c:3′′,2′′,-h:2′′′,3′′′-j]phenazine)...

Aromatic Amino Acid Monolayers Sandwiched between Gold and Silver: A Combined Tip-Enhanced Raman and Theoretical Approach

Tip-enhanced Raman scattering (TERS) measurements and theoretical calculations of the aromatic amino acids phenylalanine, tyrosine, and tryptophan sandwiched between gold and silver layers are presented...

Tip-enhanced Raman scattering (TERS) of oxidised glutathione on an ultraflat gold nanoplate

Tip-enhanced Raman scattering (TERS) spectra of a short immobilised peptide on a single transparent gold nanoplate are presented.

Optical Properties of Individual Silicon Nanowires for Photonic Devices

Silicon is a high refractive index material. Consequently, silicon nanowires (SiNWs) with diameters on the order of the wavelengths of visible light show strong resonant field enhancement of the incident...

Volume Fraction Determination of Binary Liquid Mixtures by Measurement of the Equalization Wavelength

Kinetic Studies of Surface-Initiated Atom Transfer Radical Polymerization in the Synthesis of Magnetic Fluids

We present results from kinetic studies on the surface-initiated atom transfer radical polymerization in the preparation of polymer brush-coated magnetic particles from a heterogeneous system. It is shown...

Excited-State Planarization as Free Barrierless Motion in a pi-Conjugated Terpyridine

We present femtosecond time-resolved transient absorption data and results from nanosecond time-resolved emission studies for an extended terpyridine system (4′-(4-((2,5-bis(octyloxy)-4-styrylphenyl)ethynyl)phenyl)-2,2′:6′,2′′-terpyridine)....
