This simple STM setup utilises a piezoelectric actuator constructed by deliberately cutting a piezo speaker into four quadrants. With individual drive wires attached to the four quadrants.

研究组将区域水资源可用性作为限制因素，揭示了32种开采地质资源的全球生产能力。他们发现，目前的资源开采大大超过了区域水资源限制，特别是2010年的铜开采（当前产量的37%超过了可用的水资源容量）。将生产地点转移到水资源压力较小的地区将缓解目前超出水资源限制的情况；然而考虑到经济因素，这并不现实。
