How narratives can aid memory
Prince Harry persuades Nigel to help him confront two Gallic dancers who have ... to do the work for you. How about another quick exercise? For the first 10 chemical elements – hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen ...
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 ...
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 ...
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 ...
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.
