    Percutaneous Coronary Intervention to Anomalous Right Coronary Artery and Retained Piece of Guidewire in the Coronary Vasculature (2005)

    Notes: The incidence of anomalous origin of the coronary arteries varies between 0.2% and 1.2%; the anomalous right coronary artery accounting for 6–27% of all the cases. To date technical experience on angioplasty in patients with anomalous coronary arteries reported in the literature is limited. A major factor is the selection of the guiding catheter to access the anomalous origin and also to give good support during angioplasty. We report the details of angioplasty in a patient with a similar problem and the dilemma following a fractured segment of the guidewire retained in the coronary vasculature.

    Notes: Abstract The synthesis of isoprene from the dehydration of 2‐methylbutanal is described using aluminium phosphates as catalysts. Two samples of aluminium phosphate are studied prepared from the reaction of phosphoric acid with aluminium chloride or sulphate. The chloride route gives a mixed cristobalite/tridymite AlPO4 and this is shown to be more active than a catalyst containing only the tridymite form of AlPO4 formed from the sulphate route. The AlPO4 catalysts are also shown to be active catalysts for the synthesis of isoprene from 3‐methylbutan‐2‐one, which is the major by‐product formed from the reaction of 2‐methylbutanal. The AlPO4 catalysts are deactivated due to the deposition of coke in addition to loss of phosphorus from the surface. Catalytic activity can be totally restored by a simple calcination procedure at 800°C.

    Uranium-oxide-based catalysts for the destruction of volatile chloro-organic compounds (1996)

    Notes: [Auszug] Catalytic combustion of pollutants offers considerable advantages over currently industrially operated thermal combustion. As the catalyst effects oxidative destruction at lower temperatures it is not classed as an incineration process and this eliminates many regulatory requirements. In addition, ...
