29-03-2008· 16-04-2008· Mar 29, 2008. #2. I fail to see how the circuit will work for several reasons. 1. Q1 and Q2 are PNP transistors and the collectors are tied to the + 9V. supply. This is the wrong polarity for PNP transistors. Perhaps the schematic is wrong and the emitters should be connected to the +9V. 2.

Negative ions detection in air using nano field-effect ...

15-08-2014· Negative ions in air are of great interest for the benefits for air purification and the positive effect on air conditions for healthy living []-[].Recently, a number of consumer products utilizing ion-generating technology have become available to eliminate airborne pollutants, such as dust or cigarette smoke, allergens and viruses from immediate breathing spaces [],[].

Get Price . Aug 15, 2014· We firstly demonstrated the detection of anions in air using a nano fieldeffect transistor (nanoFET) device. Negative ions in air charged the top surface of the silicon nanoFET channel affecting the fieldeffect and making a conductance change of the channel proportional to anion concentration around the nano channel sensing surface.
