The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...

Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly the same consistency throughout, with negatively-charged electrons scattered about in it like raisins in a pudding.

One of the issues with extruder-based 3D printing is that it can be very ... He prints a support structure out of HIPS then later dissolves it using Limonene. The image on the left shows the ...

In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these ... that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl ...

Atlant 3D has raised $15 million as demand grows for its manufacturing system that builds materials and devices atom by atom. Atlant 3D describes itself as a pioneering atomic-scale advanced ...

WASHINGTON : Astronomers for the first time have deciphered the three-dimensional structure of the atmosphere of a planet beyond our solar system, revealing three layers like a wedding cake on a ...

Single-atom catalysts are at the cutting edge of catalysis research, offering a blend of high efficiency, selectivity, and sustainability. Single-atom catalysts are defined by their structure where ...

"We are finding the 3D structure of the genome," said Satoshi Namekawa, professor of microbiology and molecular genetics at the University of California, Davis and senior author on one of the papers.

To understand how RNA functions, it is essential for scientists to know its 3D structure. Kihara studies protein tertiary structure prediction/comparison, protein-protein docking, protein-ligand ...
