Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook (colloq. lab notebook or lab book) is a primary record of research. Researchers use a lab notebook to document their hypotheses, experiments and initial analysis or interpretation of these
An electronic lab notebook (also known as electronic laboratory notebook, or ELN) is a computer program designed to replace paper laboratory notebooks. Lab notebooks in general are used by scientists , engineers , and technicians to document research , experiments , and procedures performed in a laboratory.

The difference between the two peak potentials (E p), ΔE p, is of particular interest. ΔE p = E pa - E pc > 0. This difference mainly results from the effects of analyte diffusion rates. In the ideal case of a reversible 1e- couple (i.e., Nernstian), ΔE p is 57 mV and the full-width half-max of the forward scan peak is 59 mV. Typical values ...
The driving force on sodium would be (−73 mV) − (60 mV) = −133 mV. Permeability is a measure of how easily an ion can cross the membrane. It is normally measured as the (electrical) conductance and the unit, siemens , corresponds to 1 C·s −1 ·V −1 , that is one coulomb per second per volt of potential.
This hinders the use of the MPV reduction on scale. Aluminium alkoxides made in situ from trimethyl aluminium reagents have far better activity requiring as little as 10% loading. The activity difference is believed to be due to the large aggregation state of the commercially available product. [11] Several side reactions are known to occur.
Just as quickly, the potential then drops and overshoots to −90 mV at time = 3 ms, and finally the resting potential of −70 mV is reestablished at time = 5 ms. All cells in animal body tissues are electrically polarized – in other words, they maintain a voltage difference across the cell's plasma membrane , known as the membrane potential .
