Microelectromechanical systems (MEMS) are the basis of many rapidly growing technologies, because they combine miniature sensors and actuators with communications and electronics at low cost. Commercial MEMS fabrication processes are limited to silicon-based materials or two-dimensional structures. Here we show an inexpensive, electrochemical technique to(More)
Advances in the microelectronics industry have made it possible to fabricate a multitude of microdevices, such as microprocessors, microsensors, microcontrollers, and microinstruments. These electronic microdevices have significantly reduced power requirements but at the same time require more attention in terms of integrated thermal management and power(More)
As a result of globalization, fossil fuels are being depleted at an alarming rate. Singapore, ranked 9th in the world as net importer of fuels [1], will have to find a more efficient way to utilize them. Over the years, Singapore has been switching its energy dependency on the cheaper natural gas [2]. However, its transportation still depends heavily of(More)
