Surface plasmon-driven photocatalysis in ambient, aqueous and high-vacuum monitored by SERS and TERS

The review described here show the plasmonic catalysis studied by SERS and TERS techniques in atmosphere, aqueous and high-vacuum environments. However, to understand the full plasmonic catalysis potential,...

Charge-Transfer Dynamics in Nanorod Photocatalysts with Bimetallic Metal Tips

CdSe@CdS dot-in-rod nanostructures tipped with AuPt bimetallic nanoparticles as cocatalyst show increased photon-to-hydrogen conversion efficiency compared to their analogues with pure Au or Pt tips. To...

A low power 10V programmable array based on NbxSi1−x Josephson junctions for metrology applications

Josephson junctions generate, when subjected to microwave irradiation, voltages with a veryhigh precision and are used in metrology applications. So-called PJVS (programmableJosephson voltage-standards)...

Synthesis and characterization of ruthenium and rhenium dyes with phosphonate anchoring groups

Re(L1)–Re(L3), a series of rhenium(I) tricarbonyl chloride complexes with bpy-R2 derivatives L1–L3 (bpy =2,2’-bipyridine, R represents the substitution at the 4- and 4’-positions), and their corresponding...

Raman spectroscopic gas sensing

Fiber and cavity enhanced Raman spectroscopic sensing of gases and pharmaceuticals

Acousto-Optic Notch Filter Dynamically Induced in a Chirped Fiber Bragg Grating

A notch filter acoustically induced in a 1-cm-longchirped fiber Bragg grating is experimentally investigated.The notch reflectivity (−5.8 to −32 dB) and the bandwidth(2.2 to 1.3 nm) are tuned by an...

Ultrafast in cellulo photoinduced dynamics processes of the paradigm molecular light switch[Ru(bpy)2dppz]2+

An in cellulo study of the ultrafast excited state processes in the paradigm molecular light switch [Ru(bpy)2dppz]2+ by localized pump-probe spectroscopy is reported for the first time. The localization...

Characterization of emergent Shiga toxin-producing Escherichia coli strains isolated from a Chilean and imported vacuum packaged beef distributed in Santiago, Chile

Shiga toxin-producing Escherichia coli (STEC) strains are an emerging zoon otic pathogen, associated with foodborne outbreaks. STEC can cause acute diarrhea, bloody diarrhea and/or hemolytic uremic syndrome...

Determination of side products in the photocatalytic generation of hydrogen with copper photosensitizers by resonance Raman spectroelectrochemistry

A combination of UV-Vis and resonance Raman spectroscopy in conjunction with electrochemistry is employed to reveal the nature of a side procduct formed when using heteroleptic Cu(I)-photosensitizers [(P^P)Cu(N^N)]+...
