Abstract: The present disclosure relates to a method for transferring a target layer to a substrate. The method includes providing a stack by forming a first transfer layer over a first substrate, forming a second transfer layer on the first transfer layer, the second transfer layer being water-soluble, and forming the target layer on the second transfer layer, such that the stack has a top surface. The method also includes bonding the top surface of the stack to a second substrate, separating the first transfer layer from the second transfer layer, and dissolving the second transfer layer in water.

Abstract: The disclosed technology relates to a logic device based on spin waves. In one aspect, the logic device includes a spin wave generator, a waveguide, at least two phase shifters, and an output port. The spin wave generator is connected with the waveguide and is configured to emit a spin wave in the waveguide. The at least two phase shifters are connected with the waveguide at separate positions such that, when a spin wave is emitted by the spin wave generator, it passes via the phase shifters. The at least two phase shifters are configured to change a phase of the passing spin wave. The output port is connected with the wave guide such that the at least two phase shifters are present between the spin wave generator and the output port.

Abstract: According to an aspect there is provided a method for automatic maintenance of a dialysis system. The dialysis system includes a plurality of filter sections where each filter section includes a blood flow channel, a dialysate flow channel, and a membrane separating the blood flow channel from the dialysate flow channel and having a plurality of pores through which substances are exchanged between a blood flow in the blood flow channel and a dialysate flow in the dialysate flow channel. The method includes determining, for each filter section of the plurality of filter sections, whether a maintenance criterion is fulfilled. The method also includes triggering a maintenance event for a filter section of the plurality of filter sections for which the maintenance criterion is fulfilled. The method also includes executing the maintenance event and optionally administering a thrombolytic agent to the blood flow channel of the filter section.
