Catalytic Efficiency of a Photoenzyme—An Adaptation to Natural Light Conditions

Cheap and safe: The catalytic efficiency of a light-dependent photoenzyme (NADPH: protochlorophyllide oxidoreductase) is investigated as a function of the excitation wavelength (see picture). It becomes...

Raman spectroscopic determination of norbixin and tartrazine in sugar

In this paper, a method for the detection of norbixin and tartrazine in sugar by means of resonance Raman spectroscopy is presented. The extraction was done in four steps using methanol and the measurements...

Spark plasma synthesis and sintering of superconducting MgB2-based materials

Superconducting (SC) and mechanical properties of spark plasma (or SPS) produced MgB2 –based materials allow their efficient applications in fault current limiters, superconducting electromotors, pumps,...

Measuring AC losses and critical current of high pressure synthesized MgB2 bulk rings by the transformer method

The results of experimental study of the critical current and AC losses in high pressuresynthesized MgB2 bulk superconductors are presented. The method is based on the use of the transformer configuration...

Radial heteroemitter solar cells based on VLS grown silicon nanowires

Silicon nanowires (SiNWs) are an interesting system for the realization of solar cells, as they offer an enhanced light absorption compared to bulk Si. However, due to their large surface, nanowire solar...

Chelating Fluorene Dyes as Mono- and Ditopic 2-(1H-1,2,3-Triazol-4-yl)pyridine Ligands and Their Corresponding Ruthenium(II) Complexes

2-(1H-1,2,3-Triazol-4-yl)pyridines (trzpy), which can be regarded as analogues to 2,2′-bipyridines, were attached to the 2- and 7-position of 9,9-dioctyl-9H-fluorene providing one monotopic and two ditopic...

Incorporation of Polymerizable Osmium(II) Bis-terpyridine Complexes into PMMA Backbones

For the first time, an Os(II) bis-terpyridine 11 complex bearing a polymerizable methacryloyl function 12 was synthesized and subsequently copolymerized with 13 MMA using the RAFT polymerization technique....

Novel Discovery of Silicon

The silicon based technologies are certainly favored because of material abundance and non-toxicity at a high level of materials control and understanding together with a huge industrial infrastructure...

Frequency Division Multiplexing Readout and Simultaneous Manipulation of an Array of Flux Qubits

An important desired ingredient of superconducting quantum circuits is a readout scheme whose complexity does not increase with the number of qubits involved in the measurement. Here, we present a readout...
