Abstract: The present disclosure discloses a sintered neodymium-iron-boron magnet and a preparation method thereof. The sintered neodymium-iron-boron magnet includes the following raw materials in mass percentage: 1%-40% of an iron powder or a steel powder with a magnetic induction intensity of more than 1.2 T, not more than 10% of a praseodymium-neodymium metal hydride powder, and a remainder of a neodymium-iron-boron fine powder, wherein the mass percentages of the above raw materials add up to 100%. The preparation method includes: weighing the raw materials in mass percentage; mixing the weighed raw materials uniformly, and then subjecting to magnetic-field press molding, isostatic pressing, sintering and tempering to obtain the sintered neodymium-iron-boron magnet.

Abstract: A cascade heat pump system for an electric vehicle includes a low-pressure-stage compression device, a high-pressure-stage compression device, and a functional heat exchange device. The low-pressure-stage compression device includes a low-pressure-stage compressor, a low-pressure-stage evaporator, a low-pressure expansion valve, and a low-pressure-stage intercooler connected in sequence. The high-pressure-stage compression device includes a high-pressure-stage compressor, a high-pressure-stage four-way valve, an air-side heat exchanger, a water-side heat exchanger, a cabin heat exchanger, and a battery heat exchanger. The compressor outlet of the high-pressure-stage compressor communicates with one of the air-side heat exchanger or the water-side heat exchanger. The air-side heat exchanger communicates with the cabin heat exchanger and the battery heat exchanger separately.

Abstract: Provided are a vehicle thermal management system of an electric vehicle and a control method thereof. The vehicle thermal management system of an electric vehicle includes a refrigeration assembly, a cabin heat exchanger, a motor-drive-side heat exchange assembly, a battery heat exchanger, and a radiator tank. The outlet of the cabin heat exchanger communicates with one of the heat exchange inlet of a chiller or the heat exchange inlet of a cabin evaporator. The inlet of the motor-drive-side heat exchange assembly communicates with at least one of the outlet of the cabin heat exchanger, the heat exchange outlet of the chiller, or the heat exchange outlet of a water-cooled condenser. The outlet of the motor-drive-side heat exchange assembly communicates with at least one of the heat exchange inlet of the water-cooled condenser or the inlet of the cabin heat exchanger.

Abstract: The disclosure provides antigenic peptides of Vascular Endothelial Growth Factor Receptor 2(VEGFR-2)/KDR. Pharmaceutical compositions including the peptides and/or antigen presenting cells that exhibit the VEGFR-2/KDR peptides on their cell surface are also provided. Methods for eliciting an immune response and for inhibiting angiogenesis by administering such pharmaceutical compositions are provided.
