Abstract: A grid sensor system for characterizing a fluid flow includes a sensor insert having a grid sensor element and a flow guide having an inlet line, an outlet line, and an insert holder arranged between the same to hold the sensor insert. A rectilinear flow path is formed by the flow guide. The insert holder is formed in such a way that the sensor insert can be inserted into the insert holder along an insertion direction extending transversely with respect to the flow path. When the sensor insert is held in the insert holder, none of the electrodes extends parallel to the insertion direction.

Abstract: The present invention encompasses a method of selectively separating Ga from wastewaters with the aid of a dialysis method. This exploits the particular complexation behaviour of Ga, which forms an unstable tetrahalo complex. This forms only in the case of a sufficiently high halide concentration. Since the halide concentration becomes lower across the membrane, the Ga-tetrahalo complex breaks down in the membrane, as a result of which the Ga is retained. Other metals such as In and Fe do not show this behaviour, and therefore the tetrahalo complexes of these metals can pass through the membrane and hence can be selectively separated off.

Abstract: The invention relates to an electronic memristive device that has a complementary analogue reconfigurable memristive bidirectional resistive switch. The device has a memristive layer sequence having a BFTO/BFO/BFTO three-ply layer and two electrodes. Titanium traps are arranged in the BFTO interfaces. As a result of mobile acid vacancies, the potential barriers at the interfaces of the electrodes with respect to the memristive layer sequence are in flexible form. By applying voltage pulses, the acid vacancies can be shifted from the interface with respect to the first electrode to the interface with respect to the second electrode, with raising of the potential barrier at one electrode bringing about complementary lowering of the potential barrier of the other electrode. The method according to the invention for operating the device proposes adapted writing processes that use the overlaying of writing pulse sequences to achieve stipulation of a state pair of complementary resistor states. In conjunction with reading pulses of adapted polarity, the device can implement fuzzy logic and be operated as an artificial synapse with the realisation of all four learning curves for complementary learning. A plurality of options for the use of the device operated according to the invention are proposed

Abstract: The invention relates to a heat exchanger having at least one partition and surface elements which project from at least one side of the partition and which enlarge the surface of the partition and around which a fluid can flow. The problem addressed by the present invention is that of proposing heat exchangers of low mass with high thermal transmission capacity. This problem is solved by means of a heat exchanger in which the surface elements are formed so as to project in the manner of fins from the partition, and the surface elements have reinforcement beads, wherein the reinforcement beads extend as far as the partition.

Abstract: A process for producing a porous metal membrane (pore size 10 nm and 1 um), a metal membrane of this type, the use of the metal membrane and also corresponding filter modules. The Dice is 1-20 microns. The plasma immersion ion implantation process is utilized by bombarding a very thin metal foil with noble gas ions accelerated by means of a first accelerating voltage, in particular from both sides. The ion current is selected so that supersaturation occurs in the metal foil. Pores, in particular under the metal surface, are then formed by bubble segregation after supersaturation. Opening of the pores formed under the metal surface by ion implantation is effected by atomization of the surface by means of bombardment with noble gas ions using a second accelerating voltage which is lower than the first accelerating voltage.
