The invention relates to a device () for detecting an analyte in a gas mixture or a liquid, comprising: (a) a polymer sorption filter () configured to separate methanol from ethanol; and/or to separate hydrogen and/or methane from interferants; and (b) means configured to detect () at least one of methanol, ethanol, hydrogen and methane. Furthermore, described is a method for detecting an analyte using the device and the use of the device.

Device and method for detecting an analyte

The fat burning analyzer includes a sampling part, an analysis unit and a processing unit. The sampling part collects a breath sample from the user, information on the conditions of the breath sample collection, and provides a sampling signal correlated to the collection condition of the breath sample. The analysis unit provides a detection signal corresponding to an acetone concentration in the collected breath sample and, as such, provides information on the breath acetone of the user (during exercise or resting). The processing unit receives the sampling signal and/or detection signal, and evaluates the sampling signal and/or the detection signal. The evaluation provides information correlated to the fat burning intensity of the user. These information can be provided as an output signal by the processing unit. Accordingly, the processing unit is equipped to provide an output signal correlated to the fat burning intensity of the user.

Fat burning analyzer

A flame spray pyrolysis process for the preparation of ultrafine titania particles coated with a smooth, homogeneous coating of one or more metal oxides is provided. The metal oxide coating is achieved by contacting the titania particles with a metal oxide precursor downstream of the titania formation zone, after the titania particles have formed. The process provides titania particles with a high rutile content and a smooth and homogeneous coating of a metal oxide.

Gas phase production of coated titania

Described is a method for the production of pure or mixed metal oxides, wherein at least one metal precursor that is a metal carboxylate with a mean carbon value per carboxylate group of at least 3, e.g. the 2-ethyl hexanoic acid salt, is formed into droplets and e.g. flame oxidized. The method is performed at viscosities prior to droplet formation of usually less than 40 mPa s, obtained by heating and/or addition of one or more low viscosity solvents with adequately high enthalpy.

Metal delivery system for nanoparticle manufacture

Dental composite filler materials comprise particles coated via an atomic layer deposition (ALD) process. The coating material has a different composition than the core particle. The difference in composition permits fine control over the refractive index of the coated particles, allowing good matching tooth enamel and to the binder materials used in the composite.

Dental composite filler particles

The present invention relates to dental composites comprising at least one nanoparticulate mixed oxide (a) of SiOwith X-ray-opaque metal oxides of one or more elements selected from the group consisting of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu which has been prepared by flame spraying.

Dental composites based on X-ray-opaque mixed oxides prepared by flame spraying

Described is a method for the production of metal oxides by flame spray pyrolysis, in particular mixed metal oxides such as ceria/zirconia, and metal oxides obtainable by said method. Due to high enthalpy solvents with a high carboxylic acid content said metal oxides have improved properties. For example ceria/zirconia has excellent oxygen storage capacity at high zirconium levels up to more than 80% of whole metal content.
