So far the analysis of indoor concentrations of formaldehyde is only possible via expensive methods, normally requiring GC or HPLC analysis in the lab. So called MOX (metal oxide) sensors theoretically permit an online-monitoring, but there is so far no instrument available for the detection of relevant concentrations in the ppb-range at reasonable costs.
Our invention presents a novel MOX-sensor based on In4Sn3O12 as sensitive layer with sensitivities for formaldehyde being two orders of magnitude above those of established reference sensors. Our sensor allows an online/realtime-monitoring of formaldehyde in day to day settings, at low cost.
Cancer patients frequently bear therapeutically relevant genome alteration. For instance, lung adenocarcinomas of patients that have never smoked carry genome alterations affecting kinases, such as EGFR mutations and translocations affecting ALK, ROS1, and RET genes. These patients can be effectively treated with an ever-growing number of kinase inhibitors. However, despite substantive cancer genome sequencing efforts a majority of tumors still lacks therapeutically tractable alterations. Scientists of the University of Cologne identified NRG1 gene fusions as ideal diagnostic and prognostic markers and targets for various tumours. The MTSS1-NRG1 fusion event has e.g. been detected in patients with small cell lung cancer and the gene fusion CD74-NRG1 has been shown to occur frequently in never smokers with invasive mucinous lung adenocarcinoma lacking KRAS mutation. The latter has been verified by several other groups.
Due to the increasing number of decentralized power feeder it becomes more and more difficult to keep up the stability of the power grid. For power feeder in low- and medium voltage power grid the ohmic part of the impedance gains more influence than in the transport grid. This means that the coupling of frequency and voltage to active and reactive power can be completely inverted compared to the common droop control. AGIDC solves this problem of droop control for decentralized power feeder in low- and medium voltage grids. AGIDC – with an impedance dependent static function – provides a droop control in a general form. The power feeding can be adapted to changing grid impedances and to other requirements from the transport grid.
Because of the symmetrical crystal structure there is no electro-optical effect in silicon. That means that in silicon the refractive index is not dependent on the applied electric field strength. The manufacturing of electro-optical components in silicon technology was therefore not possible in a cost-effective way.
A surprisingly simple and inexpensive method has now been found using chemical treatment of the silicon surface with bromine. Hereby silicon can be converted into an electro-optically active material. The induced electro-optical activity has a high thermal stability, which can even be increased by appropriate passivation layers.
A novel oxidic ternary co-catalyst containing molybdenum, which has been found to be highly active and stable in the overall photocatalytic splitting of water over gallium oxide. With this noble metal-free system a catalytic activity comparable to that of the well-established RhxCr2-xO3/Ga2O3 water splitting catalyst can be achieved. Furthermore, its activity can be easily regenerated resulting in a long service life.
