Besides negative thermal expansion, the researchers also found that changes in temperature lead to a significant variation in the porosity of the material, which is therefore highly controllable.
除了负的热膨胀效应，研究人员也发现了温度改变引起的材料多孔性的明显改变，因而这种多孔性就变得高度可控。
As long as the temperature of the material is higher than negative 100 degrees Celsius, its thermal energy can be converted into electrical energy by it.
只要温度高于负100摄氏度的物质所具有的热能都能通过此种机器转化成电能，它还能把不太集中的热源的热能通过此种机器而集中起来。
