Ziel des Vorhabens ist die Entwicklung hochaktiver, selektiver und stabiler zeolithischer Redoxkatalysatoren für die selektive Reduktion von Stickstoffoxiden mit Ammoniak. Zu diesem Zweck werden durch Kombination katalytischer Untersuchungen mit Studien zur physikochemischen Charakterisierung von Aktivkomponente und Matrix (Methoden: EPR, ferromagnetische Resonanz (FMR), Mößbauerspektroskopie, EXAFX, XPS, ISS, UV-Vis, IR, Raman, XRD) gesicherte Erkenntnisse über die erforderliche Struktur der Redoxkomponente und der zeolithischen Matrix erarbeitet, die in verbesserte Präparationsstrategien für eine neue Katalysatorgeneration umgesetzt werden. Bezüglich der Strukturierung der Übergangsmetallkomponente ist durch Kombination katalytischer mit spektroskopischen Techniken zwischen der Wirkung isolierter Ionen auf Kationenplätzen sowie intra- bzw. extra-zeolithischer Oxidaggregate zu differenzieren, wobei dem Beweis der katalytischen Relevanz von Spezies über spektroskopische in situ-Studien (EPR, UV-Vis, Raman, EXAFS) besondere Bedeutung zukommt (1.-3. Jahr).

During the period from 1974 to 2023 various cruises from BGR acquired seismic lines worldwide. The aim of these marine expeditions were a detailed survey of the geological structure of seabed.
During the period from 1974 to 2018 various cruises from BGR acquired seismic lines worldwide. The aim of these marine expeditions was a detailed survey of the geological structure.
The previous BGR-cruises with RV AURELIA in 2003 and 2004 and RV HEINCKE in 2005 and RV ALKOR in 2006 were designed to collect a grid of seismic MCS-data which should enable us to get a high-resolution overview over the upper 1-2 s TWT of the sediments of the German North Sea sector. The data format is Society of Exploration Geophysicists SEG Y. The aim of this cruise was a detailed survey in the north westernmost area of the German EEZ (exclusive economic zone), the so-called ‘Entenschnabel’ and additionally a mapping of special glacial structures off Sylt Island. The cruise was subdivided into two Legs. One outreaching additional aim was to extend the results from the previous cruises for the Late Tertiary and Quaternary sedimentary evolution into the ‘Entenschnabel’-area which was virtually unexplored by systematic shallow high-resolution seismics. During Leg 1 the BGR high-resolution multichannel seismic reflection system consisting of a GI-Gun (0.8 l) and a 500 m streamer with 36 channels and a shallow swath bathymetric system, type SIMRAD EM1200 by Kongsberg, Bergen, Norway were used. While the BGR-seismic system was used to observe the shallow subsurface down to 2 s TWT penetration depth, the swath bathymetric system was used to identify possible pockmark locations as well as sampling positions for the deployment of the BGR vibration corer during the succeeding Leg 2. All seismic records were processed onboard for the quality control and for a first interpretation loaded into GEOQUEST.
The Scientific staff and crew onboard CCGS Louis S. St. Laurent (LSL) returned September the 10th, 2001 from a scientific expedition to the Nares Strait, the northernmost waterway connecting the Arctic and Atlantic oceans. The data format is Society of Exploration Geophysicists SEG Y. The ice conditions in the strait required the support of Canada's largest ice breaker. The ship was a versatile platform for 34 scientists to accomplish their marine investigation. The LSL has a history of supporting international scientific expeditions including an oceanographic transect of the Arctic Ocean in 1994 and a biological study of the Canadian Arctic Islands in 1999. Germany (Bundesanstalt für Geowissenschaften und Rohstoffe, BGR) and Canada (Geological Survey of Canada) undertook a 5-week scientific cruise to study and explore the geological structure and evolution of the Nares Strait. The primary objective was the study of structural features relating to the formation of the Arctic Ocean and, in particular, the study of the Wegener Fault. This fault is a linear boundary between Greenland and Ellesmere Island which was noted by the German scientist Alfred Wegener in 1915 and later became the subject of a major scientific controversy. The co-operative cruise, which was planned over a period of 2 years, provided the basis for a wide range of scientific investigations, from marine seismic work and climate change studies through airborne magnetic investigations to geodetic survey measurements and geological sampling onshore. Systematic geophysical offshore studies in this key area had not been undertaken before. Where towing of seismic equipment was not possible because of ice coverage, magnetic maps were made using a helicopter-borne magnetic sensor system. Sediment and water samples taken during the cruise provide information on changes in climate and sea ice cover from the last ice-age to the present. An 11 m-long sediment core from outer Jones Sound is the longest core ever taken in the Canadian Arctic channels and holds clues to the detailed climate history of northern Baffin Bay.
In July/August 1988 a seismic reconnaisance survey was carried out with F.S. Polarstern on the perennially ice covered East Greenland shelf between latitudes 73°N and 81°N. The data format is Society of Exploration Geophysicists SEG Y. 14 reflection seismic lines with a total length of 2.016 km and 12 sonobuoy refraction profiles were recorded. The following results were obtained: •On the wide Holm Land shelf province north of 79°N three possible Cretaceous rift basins were observed. •A buildup of layered extrusive basaltic rocks forming a wedge of seaward dipping reflectors underlies the Holm Land continental slope. •On the Northeastern Greenland shelf province the existence of a wide sedimentary basin was demonstrated north of 76°N. •South of 76°N four volcanic structures from the continent to ocean were observed: The zone of Early Tertiary plateau basalts (zone I) that occur landward of an escarpment, a flat lying basaltic flow unit immediately seaward of the escarpment (zone II), an elongate wedge of seaward dipping reflectors (zone IIIa), a basaltic flow unit which in places shows seaward dipping beds of short length (zone IIIb), and the oceanic crust. •Dyke swarms and intrusions of inferred Neogene age were recognized at several locations.
Ziel ist es Krankheitssymptome an Zuckerrübenblättern mit Hilfe von Kameras in mobilen Endgeräten (Smartphones, Handys, etc.) zu fotografieren, diese per Internet auf einen Server zu übertragen, dort durch Erkennungsroutinen analysieren zu lassen und das Ergebnis zurück zu senden. Dabei sollen durch Farb- und Mustererkennung der gesendeten Aufnahmen die möglichen Blattkrankheiten eingeschränkt werden. Aus einer Krankheitsbibliothek werden dem Nutzer Aufnahmen gesandt, so dass er ähnliche Ausprägungen der Krankheiten direkt vergleichen kann. Nach Bestimmung der Krankheit(en) kann der Nutzer durch GPS seinen Standort bekannt geben und unter Berücksichtigung weiterer Geo- und Schlagdaten im Beratungsportal der Länder ISIP (www.isip.de) eine Schaderregerprognose berechnen lassen bzw. Empfehlungen und Handlungsanweisungen abrufen. Im letzten Projektjahr ist vorgesehen, die Übertragbarkeit der Methode auf Blattkrankheiten in Getreide zu untersuchen. Das Ergebnis wird ein modularer Erkennungs-Algorithmus sein, der sich schnell und unkompliziert auf andere Blattkrankheiten anpassen lässt. Von den Partnern INRES und BI-T wird ein Algorithmus erstellt, der auf der Basis von Bildern aus Smartphones Blattkrankheiten an Pflanzen erkennt. Von ZEPP werden Programme erstellt, die solche Algorithmen routinemäßig auf Smatphones und Servern rechnen. ZEPP macht die Tools in der Praxis bekannt und koordiniert das Projekt. ISIP implementiert u. betreibt die Tools auf seinen Internetservern.
