Abstract: A method is described for use in a process for the conversion of an alcohol, the method including the step of contacting a composition comprising a first alcohol with a catalyst composition. Catalyst composition described comprises: i) a source of a Group VIII transition metal; ii) a phosphine ligand of formula PR1R2R3, wherein R1, R2 and R3 are the same or different; and iii) a base. In examples described, the alcohol which is converted comprises ethanol and the product comprises butanol.

Abstract: A compact combination sensor is provided for physiological parameters, which can be worn behind the ear. The combination sensor has a heat flux sensor (1) for detecting two temperatures (Th1, Th2) for determining the body core temperature (Tc), an acoustic sensor (2) for measuring the heart rate (HR) and for detecting speech signals, as well as a measured signal evaluating unit (4, 5, 7). A communications interface (8) is provided for transmitting the processed data from the measured signal evaluating unit (4, 5, 7) to a communications unit (9) are located in the sensor carrier (11).
