Title: A method and switching circuit for connecting and disconnecting current to a load having inductance
Inventor: MARKUS HEINRICK
IPC: H03K17/687
Filed: 2020-07-31
Abstract: Switching circuit and method for disconnecting a current providing power line P (at first terminal T1) from a load R1 and series inductance L1 (at second terminal T2), and a primary solid state or discrete solution switch between the first & second terminals T1/T2, whilst the turn off/turn state is controlled by a primary control command 11. The circuit further comprises one or more protection branches (B1-B4) connected in parallel with the primary switch arrangement 10 each protection branch comprising a series connected ballast resistive element RB1-RB4 and a secondary solid state/discrete switch (S1-S4) operable by branch turn on or turn off control commands; and a timing circuit 13,13’ configured to apply to the secondary switch S1-S4 of each protection of the protection branch a branch turn off control command (12B1-12B4) which is delayed by a predetermined time interval relative to when a primary turn off control command is applied to the primary solid state or discrete solution switch arrangement 10 (figures 5A-D). The timing control may turn off the secondary switch at a speed to reduce or negate the energy dissipation in the inductance. The timing circuit may apply a respective branch turn off signal to the respective branches in a sequential manner, each delayed by a different time with respect to the primary turn off command signal. The primary solid state/discrete switch may comprise MOSFET or IGBT devices connected in parallel, and which is protected from inductive over-voltage breakdown if the load is short circuited. The timing may comprise at least one RC time circuit having a set time constant or may be a counter or microprocessor.

Title: Method for preparing graphene by mechanical exfoliation and application thereof
Inventor: JIANFENG XU
IPC: C01B32/19
Filed: 2021-12-29
Abstract: Provided are a method for preparing graphene by mechanical exfoliation and an application thereof, the method comprising the following steps: (1) dispersing a graphite raw material in a foaming agent aqueous solution to obtain a graphite pre-dispersion; and (2) grinding the graphite pre-dispersion, and then obtaining graphene by washing using water, and centrifugal fractionation. The foaming agent aqueous solution comprises the following components: sodium α-alkenyl sulfonate, sodium fatty alcohol polyoxyethylene ether sulfate, coconut oil diethanolamide, polyethylene glycol, and water. Graphite is used as a raw material, graphite is immersed in the foaming agent aqueous solution, and then ground, and the high-speed stirring effect of a grinding device drives the high-speed movement of a grinding medium to generate an impact, friction and shear force on the graphite. The foaming agent produces a large amount of stable and fine foam in a closed grinding chamber, a large amount of foam can generate a pushing action, and supports the graphite, and a contact surface between the graphite and the grinding medium is increased, thereby achieving a good exfoliation effect.
