<strong>Institute</strong> <strong>for</strong><br />
<strong>Nanoscale</strong> <strong>Physics</strong> <strong>and</strong> <strong>Chemistry</strong><br />
INPAC’s mission:<br />
Investigation of the effect of<br />
nanostructuring <strong>and</strong> nanoscale<br />
confinement of charges, spins,<br />
<strong>and</strong> photons on the electrical,<br />
magnetic, optical, <strong>and</strong> chemical<br />
properties of inorganic, organic,<br />
<strong>and</strong> biomaterials in order to<br />
reveal the fundamental relation<br />
between quantized confined<br />
states <strong>and</strong> physical <strong>and</strong> chemical<br />
properties of these materials<br />
