Schnappschuss der Evolution: Die mit modernster Tunnelmikroskopie erstellte Aufnahme zeigt die Selbstorganisation von nanometergroßen, molekularen Komponenten auf einer Kupferoberfläche - einmal als Simulation (im Hintergrund), einmal als experimentelles Abbild der Moleküle selbst (im Vordergrund). Deutlich erkennbar ist die größenabhängige Anordnung zweier Molekülarten (dunkel- und hellblau) in leiterartigen Teilstrukturen. Der Abstand zwischen den molekularen "Sprossen" beträgt ca. einen Nanometer (1 Milliardstel Meter).

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
