Nanoparticle films crack at certain thicknesses (left). By adding layers of thinner films, cracking can be avoided (right).

Two of these stars can be found in the intriguing binary system known as Cygnus OB2 #9. In 2011, NASA's Swift satellite, the European Space Agency's XMM-Newton observatory and several ground-based facilities took part in a campaign to monitor the system as the giant stars raced toward their closest approach.

Heterogenized homogeneous nanocatalysts are sustainable as shown by these TEM images in which there is almost no difference in the cluster size of dendrimer-encapsulated gold nanoclusters (white spots) before (left) and after cyclopropanation reactions.

Today, the state of the art regarding the diagnosis of cancers is focused on tumor identification on sub-cellular scales. Through this technique, the patient-borne cost of the treatment is cut down and the cure success rate is increased considerably. Accordingly, we were highly determined to develop this instrument in order for localization of cellular diagnostics technology in Iran.

The GeS “nanoflowers” have petals only 20-30 nanometers thick, and provide a large surface area in a small amount of space.

This illustration depicts DNA molecules (light green), packaged into nanoparticles by using a polymer with two different segments. One segment (teal) carries a positive charge that binds it to the DNA, and the other (brown) forms a protective coating on the particle surface. By adjusting the solvent surrounding these molecules, the Johns Hopkins and Northwestern researchers were able to control the shape of the nanoparticles. The team’s animal tests showed that a nanoparticle’s shape could dramatically affect how effectively it delivers gene therapy to the cells. The cartoon images in the foreground, obtained though computational modeling, matched closely with the gray background images, which were collected through transmission electron microscopy.
