  • Publication number: 20210260658
    Abstract: A method for the preparation of isolated noble metal atoms in a solution comprises mixing a protective agent, a precious metal compound, and a reducing agent thoroughly. At certain temperature, isolated noble metal atoms are formed after reaction, thereby leading to isolated noble metal atoms which are stable in the solution. Isolated noble metal atoms on solid material surface can be prepared by impregnating a noble metal atom solution onto a solid medium. Alloys and catalysts etc. can be prepared by using the single atoms solution as raw material. The invention achieves, for the first time, the preparation of reduced single atoms in a solution phase. Formation of metal nanoparticles is avoided compared to the conventional synthesis of metal materials in solution phase. Compared with solid surface supported monoatomic materials, this invention allows for the preparation of materials that are characterized by high metal loading and high stability.

  • Patent number: 10218234
    Abstract: An electric motor in which at least one of the rotor and the stator has an asymmetric design is disclosed. The electric motor is divided into a number of segments, where each segment has an equal number of windings and an equal number of poles. The physical construction of each pole within a segment is identical and the number of turns of each winding within a segment is identical. The asymmetry is formed by varying the physical construction of the either the rotor or the stator within one segment from the corresponding construction of the rotor or stator in the other segments. The asymmetries are designed to improve one or more operating characteristics such as sensorless performance, torque ripple, or cogging torque in the motor.
