Prof Martin Kuball of the University of Bristol’s School of Physics said: “Semiconductors can be made to conduct positive or negative charges and can therefore be designed to modulate and manipulate current. However, these semiconductor devices do not stop with Silicon, there are many others...
The other benefit of earlier mitigation results from the time value of money. Applying a 4% discount rate in effect assigns a 4% rental charge each year to additional carbon in the atmosphere. That equals the price of borrowing money at a commonly estimated long-term cost of capital to pay...
When a fixed voltage is applied to the positive and negative electrodes of the electrochemical cell, reactions occur at the working electrode (anode) and the counter electrode (cathode). Taking the example of a carbon monoxide sensor, the chemical reaction can be represented by the following equat...

By doping B in the carbon structure, the positive binding energy between the graphene sheet of the hard carbon and Na changes to a negative value. B3+ transfers three electrons to the graphene sheet, which leads to strong interaction between the Na atoms and the graphene sheet in the ...
The lead–carbon batteries were placed inside a constant temperature chamber, and the fixture of the battery testing system was attached to the positive and negative terminals of the lead–carbon battery. The battery testing system was controlled by a computer to conduct charging and discharging ...
At neutral pH the NOM has a significant negative charge which can affect the adsorption in several ways. At low surface concentrations on activated carbon with positive surface groups there is direct surface-NOM electrostatic attraction (screening reduced adsorption). At higher surface concentrations ...
On noble metals (e.g., Pt, Ir, Au), the region of potential in which the OER is studied is far removed from the potential of zero charge in the positive direction. Thus, only negatively charged impurities will be heavily adsorbed, and the nature of the anion in the electrolyte will in...
The conductivity of the polymer can be tuned via various positive (p) or negative (n) dopants. The p-type dopants include electron-accepting species such as Br2, I2, H2SO4, HClO4, NO2, NO+, SbCl6−, SO3, and FeCl3 [31,32,33], while n-dopants are sodium naphthanilide, Na/K...
