there’s another challenge, the industrial production of graphene sheets. The adhesive tape method is good for producing small samples for research purposes but we need a reliable way to mass produce graphene in large sheets so it can be sold to companies that manufacture transistors for example....
. For example, in many small rodent species and birds, the long days of spring and summer are stimulatory to reproductive activity, while the short days of fall and winter are inhibitory. The value of using the seasonal change in day length for the timing of the reproductive season is ...
Another way of suppressing high-frequency signals in a circuit is to wrap a few turns of the conductor around a ring or torus made of ferrite. If turns of two conductors are wound around the same ring they are magnetically linked by the ferrite. Signals from one conductor produce a magnetic...
Everyone is so busy. We want too much and in the process of getting it we miss so much.” He stopped for a while. “It makes me lonely and sad.” Then he looked at me, “I just want to hear your voices.” I think of all the voices on the radio he has spent a lifetime lis...
The operation of integrated circuits (IC) at elevated temperature is a major cause of failures in electronic devices and a critical problem in developing more advanced electronic packages [1]. One such example of an electronic device is the electronic control unit (ECU) whose function in automotiv...
Water molecule is a good example of this. The oxygen atom in the water molecule is more negative than the hydrogen atoms. Thus, individual water molecules can form a so-called hydrogen bond with each other through the dipole-dipole interaction between the oxygen atom on one molecule and a ...
