This interesting issue has a theme of “Innovative Multitasking Engineering”. All the 5 best papers in such issue were contributed from some prominent scientists from 3 different countries of Indonesia, Canada and Malaysia. The marvelous thing among the best 5 papers was the discovery for the first time about the fabrication and test of flexible thin nanobattery with a water resistant quality. Furthermore, the energy of the battery can be just coming out by bending it. In addition, the control of the output voltage was just dependent of the bending angles. This was a good example of a very good collaboration among two to three distinguished scientists from different countries.
