This rotating image shows the 3D structure of a protein using two different imaging techniques: Cryo-MET and X-ray crystallography. This sample image is Immunoglobulin G, the most abundant antibody in the human immune system. The two images do not align...
Grammatikopoulos created this simulation of palladium nanoparticles colliding at 1000 Kevin, or about 727 degrees Celsius. At this hot temperature, the nanoparticles meet, fuse, and crystallize, forming one large homogenous product.
Grammatikopoulos created this simulation of palladium nanoparticles colliding at 300 Kevin, or about 27 degrees Celsius. The nanoparticles meet, then fuse, then crystallize in orderly planes.
On the left you can see dendrites with different numbers of spines and visually watch how the molecules inside spread out, or diffuse, differently when there are more spines. On the right, you can numerically see the distribution of molecules in...
In the upper left box you can see all parts of the neuron in this model, the external structure and internal compartment (ER) that holds calcium (yellow), and the proteins involved in opening the calcium channel (blue, bright magenta and dark magenta)....
