You have an extra pair of braces there, get rid of them.
Have a look at package siunitx, you µ should be upright, not italic.
Look what strange code you generated. I guess this comes from clicking on too many buttons, i would use ERT-boxes instead.
Compare the output of the two separated lines by clicking on
open iin writelatex.

\section{03/03/2016 : GK-Supercaps, pH-effect}
\subsection*{Motivation: }
to test the idea of increasing the cyclability by adjusting pH. Solubility
of the products of $\ce{{MnO-Mn3O4-Mn2O3-MnO2}}$ transitions increases
as pH increasing \cite{Chouaib1981}. So, the tests at different pH
down from the conventional pH=14 (1M NaOH) are planned.
\subsection*{Preparation :}
\subsubsection*{Catalyst:}
The powder was prepapred by GK last year. It was utilized in a numerous
experiments last year (see experiments from 31/07/2015 to 02/10/2015).
\subsubsection*{Electrode:}
Generally, all electrodes are prepared to have 47 $\mathrm{{\mu g/cm^{2}}}$
of oxide per geometric surface area of GC support. The latter is 0.071
$\mathrm{{cm^{2}}}$, which makes 3.37 $\mathrm{{\mu g}}$ of oxide
in the deposit, or, for \SI{34}{\percent} \ce{Mn3O4}-Vulcan-ISAC,% taht would be better
in the deposit, or, for 34\% $\ce{\mathrm{\ce{{Mn3O4}}}}$-Vulcan-ISAC,
9.81 $\mathrm{{\mu g}}$ of the catalyst. The deposition is done from
0.3 mg(oxide)/ml($\ce{{H2O}}$) suspension, thus one needs to deposit
11.23 $\mathrm{{\mu l}}$ of the ink. It is done in 3 steps, with
3.74 $\mathrm{{\mu l}}$ of ink deposited each step. The drop is dried
under $\mathrm{{N_{2}}}$ flow, ca. 10-15 min. After the last step,
a quote of the solution of ionomer (Fukuyama), 2 $\mathrm{{\mu l}}$
is deposited for the layer stability.
\subsubsection*{Electrolyte:}
0.1 M NaOH, 250 ml;
RE is always in 1 M NaOH
\subsubsection*{Results and discussion:}
\paragraph*{1. \label{par:1.-First-CV}First CV cycling to stabilize the sample,
15 cycles, 20 mV/s; }
limits:
1 M NaOH, $\mathrm{{pH}\approx14}$, -0.50 .. 0.30 V MMO
0.1 M NaOH, $\mathrm{{pH}\approx13}$, -0.44 .. 0.36 V MMO
