Problems of heat transfer in molecules are central in many parts of physical sciences and nanotechnology. Guiding energy flow in molecules is the key element in controlling chemical and biological processes, for example, reaction pathways and molecular dynamics. In molecular electronics, where molecules are the active components in nanoscale electronic circuits, local heating may cause structural instabilities undermining the device integrity. Engineering good thermal contacts and cooling the nanosystems are necessary for a stable operation mode. Minimization of mechanical devices, e.g. refrigerators and pumps, to the molecular scale is a topic of great interest for technologies such as chemical sensing, power generation and energy conversion.

分子传热问题是物理科学和纳米技术许多领域的核心问题。引导分子中的能量流动是控制化学和生物过程（例如反应途径和分子动力学）的关键要素。在分子电子学中，分子是纳米级电子电路中的活性成分，局部加热可能会导致结构不稳定，从而破坏器件的完整性。设计良好的热接触和冷却纳米系统对于稳定的运行模式是必要的。尽量减少机械设备，例如冰箱和泵，到分子尺度是化学传感、发电和能量转换等技术非常感兴趣的话题。
