Today, near-room-temperature refrigeration is almost entirely based on a vapor-compression refrigeration cycle.

Solid state and materials chemistry have made a tremendous impact and have experienced growth in recent years, particularly for rare earthcontaining materials.

The application of magnetism and magnetic materials pervades our modern civilization in the form of electrical power, communications and information storage.

The unique properties of the rare-earth elements and their alloys have brought them from relative obscurity to high profile use in common hightech applications.

我们的科学家团队拥有各种研究领域经验,包括生命科学、材料科学、化学合成、色谱、分析及许多其他领域.
