Abstract: A method and system for concentrating an analyte (A). Liquid droplets (D) of an extractant liquid (Le) are adhered to a wall (10w) of a container, e.g. capillary tube. A sample fluid (Fs) comprising the analyte (A) is provided in the container (10) to contact the liquid droplets (D). The analyte (A) has a higher solubility in the liquid droplets (D) than in the sample fluid (Fs). This causes the analyte (A) to be extracted from the sample fluid (Fs) and concentrated in the liquid droplets (D). After extraction, the liquid droplets (D) are collected, e.g. scraped, from the wall (10w) for obtaining the concentrated analyte (A). A concentrated liquid (La) can be formed by collecting the liquid droplets (D) from the wall (10w). The analyte (A) can be measured in the concentrated liquid (La) using any suitable measurement technique.

Abstract: Disclosed is a device for simulating the movement of an endoscope in an environment, including: a tube modelling an endoscope tube; and a tracking module including a housing into which the tube is insertable and movable. The tracking module includes a detector of movements of the tube in the housing and a unit for communicating the detected movements to a controller. The controller is configured to generate, at each instant, an image of a portion of an environment based on the movements of the tube detected by the detector so as to simulate the movement of an endoscope in the environment. The tracking module includes a fastener adapted to fasten the tracking module in a releasable manner onto a support.

Abstract: A method of printing a cellular solid (120) by direct bubble writing comprises introducing an ink formulation (102) comprising a polymerizable monomer and a gas (104) into a nozzle (106), which includes a core flow channel (108) radially surrounded by an outer flow channel (110). The ink formulation is directed into the outer flow channel (110) and the gas is directed into the core flow channel (108). The ink formulation (102) and the gas (104) are ejected out of the nozzle (106) as a stream of bubbles (112), where each bubble includes a core (114) comprising the gas and a liquid shell (116) overlying the core that comprises the ink formulation. After ejection, the polymerizable monomer is polymerized to form a solid polymeric shell (118) from the liquid shell (116), and the bubbles are deposited on a substrate (122) moving relative to the nozzle (106). Thus, a polymeric cellular solid (120) having a predetermined geometry is printed.

Abstract: A method for a PUK authenticated communication includes creating an optical challenge in a time-frequency domain, providing the optical challenge to a tPUK which includes a spatial input channel and a plurality of spatial output channels, and detecting in which of the plurality of spatial output channels a short temporally focused pulse is created. The tPUK provides a complex challenge-response behavior in the time-frequency domain. The optical challenge is created so that the tPUK creates the response having a short temporally focused pulse in only one of the plurality of spatial output channels of the tPUK.

Abstract: Systems and related methods are described that can be used for etching and/or depositing materials. In some embodiments, the systems comprise an outer chamber and an inner chamber. The inner chamber can comprise a lower chamber part and an upper chamber part which are moveable with respect to each other between a closed position and an open position. The upper chamber part and the lower chamber part can abut in the closed position. The upper chamber part and the lower chamber part may further define an opening in the open position.

Abstract: Aspects of the present disclosure describe improved supercontinuum generation based upon alternating optical dispersion along a waveguide length that advantageously generates much more spectral bandwidth than possible with conventional, prior art techniques without losing coherence as well as supporting a larger range of pulse energies (i.e., for lower than conventionally allowed pulse energies or high pulse energies).

Abstract: Method and apparatus for measuring an amount of superparamagnetic material in an object, the method including a) applying a magnetic field having a first component alternating with a first period to the object and a magnetic field strength lower than a magnetic field strength at which the superparamagnetic material is driven in saturation; b) measuring a first magnetic susceptibility of the object with a detection coil; c) applying a static second component to the magnetic field for a second period being equal or larger than the first period, the strength of the magnetic field during the second period is such that the superparamagnetic material is driven towards saturation; d) measuring a second magnetic susceptibility of the object with the detection coil during the application of the static second component; and e) determining the amount of superparamagnetic material from a difference between the measured first and second susceptibility of the object.
