“At the present time (1975) there is no experimental evidence for the existence of magnetic charges or monopoles, but chiefly because of an early, brilliant theoretical argument by Dirac, the search for monopoles is renewed whenever a new energy region is opened up in high energy physics or a new source of matter, such as rocks from the moon, becomes available [1]. ” Dirac argued that a monopol...

The recent advent of microelectromechanical systems (MEMS) or micro-devices has generated excitement in many diverse fields. In the area of micro-fluidics liquid pumps are highly desirable for fluid transport and atomization. A recent and popular example of this is the inkjet, which self-aspirates ink from a reservoir and then transports it to a chamber for expulsion as a single droplet during ...

In recent years, a very large amount of scientific work has been achieved around Micro-Electro-Mechanical Systems (MEMS). Some industrial success stories (accelerometers, gyroscopes and MOEMS) have shown their maturity. MEMS are now starting to take place around us in our everyday life as the microelectronic did 20 years ago. However, a lot of effort is still needed for the integration of ICs a...

We present a microelectromechanical system (MEMS) graphene-based pressure sensor realized by transferring a large area, few-layered graphene on a suspended silicon nitride thin membrane perforated by a periodic array of micro-through-holes. Each through-hole is covered by a circular drum-like graphene layer, namely a graphene "microdrum". The uniqueness of the sensor design is the fact that int...

As the Army transforms into a more lethal, lighter and agile force, the technologies that support these systems must decrease in size while increasing in intelligence. Microelectromechanical systems (MEMS) are one such technology that the Army and DOD will rely on heavily to achieve these objectives. The MEMS devices within these systems will be required to last as long as the lifetime of the w...
