Boron: It's What Makes the Hope Diamond Blue
Boron is carbon's neighbor on the periodic table, which means it can do a passable carbon impression and wriggle its way into the matrix of a diamond. But it has one fewer electron, so it can't quite form the same four perfect bonds. This different ...
B and N isolate-doped graphitic carbon nanosheets from nitrogen-containing ion-exchanged resins for enhanced oxygen reduction
B,N-codoped carbon nanostructures (BNCS) can serve as alternative low-cost metal-free electrocatalysts for oxygen ... boron-nitride (BN) easily formed during the synthesis of BNCS, leading to a unsatisfactory ORR activity. Therefore, it has been ...
Pique the Geek 20120722: More on Carbon
Carbon is sort of unusual in that it is an element that we can see in a fairly pure form in normal life. Most pure elements are either gases (think nitrogen or oxygen ... of us have seen pure copper. So why is graphite so soft? It has to do with its ...
The Geometry of Snowflakes -- Oxygen Structure
Why do freezing water molecules arrange ... The four Elements following Hydrogen, Helium(2), Lithium(3), Beryllium(4), and Boron(5), all have box-like shapes. But the next 5, Carbon(6), Oxygen(8), Nitrogen(9), Fluorine(10) and Neon(11) are all spheres.
Hydrogen Breakthrough Could Open The Road To Carbon-free Cars
A new breakthrough in hydrogen storage technology could remove a key barrier to widespread uptake of non-polluting cars that produce no carbon dioxide emissions. UK scientists have developed a compound of the element lithium which may make it practical to ...
