Chromium hexacarbonyl vapour was carried by argon through a heated capillary and impinged onto silicon substrate. Due to the temperature of the capillary, the chromium hexacarbonyl dissociated upon impact and chemisorbed onto the surface - forming horns growing towards the axis of the capillary.

The armadillo’s armor is made of triangular and hexagonal tiles that have the same composition as bone. The tiles are connected by collagen fibers, which give the armor its flexibility. The tiles are covered with a dark-brown layer of keratin, the material that hair and nails are made of.
The alligator’s body is covered in scales made of the same material as bone. The scales are connected by collagen fibers, which make the animal’s carapace flexible. A cross-section of the scales shows that they are made of a sandwich-like structure, with an extremely porous layer between two layers of hard bone.

These are nanoparticles coated with carbon (like a Tootsie-Roll Pop), which scientists are testing as a possible ingredient for better batteries. These studies often reach into the nano-level as researchers try to understand activity at the atomic scale in order to custom-design new materials for batteries.

This simulated cross-section shows how the lipid-like peptoids interact to form a membrane. Each peptoid has two sections: a fatty-like region that interacts via benzene rings (shown in pink) with its neighbors to form a sheet. And a water-loving region that juts above or below the flat sheet. Each region can be designed to have specific functions.

In this illustration, an infrared laser beam (orange) triggers atomic vibrations in a thin layer of iron selenide, which are then recorded by ultrafast X-ray laser pulses (white) to create an ultrafast movie. The motion of the selenium atoms (red) changes the energy of the electron orbitals of the iron atoms (blue), and the resulting electron vibrations are recorded separately with a technique called ARPES (not shown). The coupling of atomic positions and electronic energies is much stronger than previously thought and may significantly impact the materialís superconductivity.

A team of researchers led by the University of California San Diego have discovered what’s responsible for making the teeth of the deep-sea dragonfish transparent. This unique adaptation, which helps camouflage the dragonfish from their prey, results from their teeth having an unusually crystalline nanostructure mixed with amorphous regions. The findings could provide “bioinspiration” for researchers looking to develop transparent ceramics.

Work by a team of Penn State researchers led by Mohammad Reza Abidian may lead the way to the microencapsulation of chemotherapeutics. The breakthrough would allow doctors to directly inject medication to a brain tumor area and control the amount of medicine being dispersed. The work allows for control of size, shape, and drug release.
