Aggregation-induced optical responses are ubiquitous among a wide range of organic and inorganic compounds. Here, we demonstrate an unprecedented effect of aggregation on the photoluminescence (PL) profiles of [core + exo]-type [Au8]4+ clusters, whic

In vibration engineering, unnecessary vibration energy can be dissipated by a damper into not only heat energy but also electric energy for energy harvesting. But a common damper for energy harvesting has to be tuned into a resonance in order to rese
