摘要:
The present invention relates to a method for producing a chiral amine, performing a transamination reaction of a prochiral amino acceptor and an amino donor in a first solution in the presence of a transaminase, thereby forming a chiral amine and a coproduct in said first solution, characterized in that said amino donor is a high molecular weight (HMW) amino donor, the molecular weight of the HMW amino donor being at least 150 g/mol; or said amino donor is affixed on a support, the total molecular weight of the amino donor and the support being at least 150 g/mol. A device for producing and separating a chiral amine is provided as well.
摘要:
Methods and systems for monitoring individual cell voltages of an energy storage system. The measured cell voltages can be reported back to a central controller. Based on parameters such as the overall health of the system, this controller can be adapted to decide which cells to balance, in which direction and optionally for how long. Balancing can be performed by cell monitoring and balancing units which can be implemented in hardware, i.e. as one or more circuits. The decision information from the controller can be reported to the cell monitoring and balancing units as a command. The cell monitoring and balancing means can execute the command, for example irrespective of the voltage or SoC of the cell connected to it.

An inorganic membrane, preferably modified or grafted with an organic functional group, is further functionalized with a metal, such as silver, for use in the membrane based separation methods.
摘要:
The present invention relates to a system (1) for capturing carbon dioxide from ambient air (3), the system comprising: a CO2 trapping structure (4) for placement in ambient air (3), said ambient air (3) comprising carbon dioxide, said CO2 trapping structure (4) comprising a porous member having pores which are interconnected between opposite faces of the member; and an air conducting structure (2) comprising a means for forcing the ambient air (3) through the CO2 trapping structure (4), wherein the CO2 trapping structure (4) is removable positioned with respect to the air conducting structure (2) such that the air passing through the air conducting structure (2) passes through the pores of the CO2 trapping structure (4), said pores having walls comprising an amine which binds the carbon dioxide from the ambient air (3); and a means (5) for moving the CO2 trapping structure (4) to an environment (6) being at a temperature comprised between 60°C to 100°C, preferably between 65°C to 95°C, more preferably between 65°C to 80°C, and being at a reduced pressure so as to release the carbon dioxide from the CO2 trapping structure (4). The use of the system and a related method are provided as well.
摘要:
Device (10) for simultaneously determining a mass transport of a fluid and a mass transport of a substance dissolved in the fluid, comprising at least two cartridges (11-14) filled with a porous matrix, and assembly means (15), configured to keep the cartridges together, characterized in that the top side (111) and the bottom side (112) of each cartridge are non-permeable and the side wall (113) is permeable, and in that the assembly means are configured to keep the cartridges together according to a stack, in which the cartridges may be flowed through in parallel without cross-contamination.
