  • Publication number: 20210163359
    Abstract: Disclosed is a method for preparing high-strength coral aggregate concrete under low pressure conditions, including the following steps: weighing cement, mineral admixture, coral aggregate, mixing water, water reducer, and defoamer; mixing the cement and the mineral admixture well to obtain a cementing material; putting the coral aggregate, sea water, water reducer, defoamer, and 55-85% of the cementing material into a closed mixing system to stir for 10-15 min under low pressure conditions, and pouring the remaining cementing material into the mixing system to stir for additional 10-15 min to prepare the high-strength coral aggregate concrete. The high-strength coral aggregate concrete obtained has advantages of high mechanical properties, high compactness, excellent impermeability and durability, drawing on local resources in construction engineering on remote islands and reefs, and maximum resource utilization.

  • Publication number: 20200250567
    Abstract: Provided are a method for coupling any two qubits from among multiple superconducting qubits and a system thereof, which are applied to an occasion provided with a multi-superconducting-qubit array and a magnetic film material capable of implementing spin waves. The method includes: disposing a magnetic film material below a multi-superconducting-qubit array; forming, through a combination of magnetization directions of magnetic domains in the magnetic film material, multiple channels through which the spin waves pass; disposing multiple qubits of the multi-superconducting-qubit array above the multiple channels through which the spin waves pass correspondingly to implement a coupling between each qubit and the spin waves; and disposing at least two qubits above one spin wave channel and implementing a coupling between the at least two qubits through the coupling between each qubit and the spin waves.

  • Publication number: 20150060277
    Abstract: There is provided a nanopore system including a nanopore in a support structure. A first reservoir is in fluidic connection with the nanopore and a second reservoir is in fluidic connection with the nanopore. The support structure separates the first and second reservoirs. A pressure source is connected to one of the first and second reservoirs to apply an external pressure to one of the first and second reservoirs. A voltage source is connected between the first and second reservoirs to apply a voltage bias between the first and second reservoirs, across the nanopore. This system enables a method for analysis of species in solution, wherein there is provided to the nanopore a fluidic solution that includes a species for translocation through the nanopore, with an external pressure applied to the species in fluidic solution and a voltage bias applied across the nanopore.

  • Publication number: 20150060276
    Abstract: There is provided a nanopore system including a nanopore in a solid state membrane. A first reservoir is in fluidic connection with the nanopore, the first reservoir being configured to provide, to the nanopore, nucleic acid molecules in an electrolytic solution. A second reservoir is in fluidic connection with the nanopore, with the nanopore membrane separating the first and second reservoirs. A pressure source is connected to the first reservoir to apply an external pressure to the first reservoir to cause nanopore translocation of nucleic acid molecules in the solution in the first reservoir. A voltage source is connected between the second and first reservoirs, across the nanopore, with a voltage bias polarity that applies an electric field counter to the externally applied pressure. Force of the externally applied pressure is greater than force of the electric field during nanopore translocation by the nucleic acid molecules.
