Hace 5 días · Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.

Hace 1 día · Atoms are the basic particles of the chemical elements.An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons.The chemical elements are distinguished from each other by the number of protons that are in their atoms. For example, any atom that contains 11 protons is sodium, and any atom that contains 29 protons is copper.
Hace 3 días · The single-atom Fe-N-C catalyst has shown great promise for the oxygen reduction reaction (ORR), yet the intrinsic activity is not satisfactory. There is a pressing need to gain a deeper understanding of the charge configuration of the Fe-N-C catalyst and to develop rational modulation strategies.
Hace 5 días · Matter waves are a central part of the theory of quantum mechanics, being half of wave–particle duality.At all scales where measurements have been practical, matter exhibits wave-like behavior.For example, a beam of electrons can be diffracted just like a beam of light or a water wave.. The concept that matter behaves like a wave was proposed by French physicist Louis de Broglie (/ d ə ˈ b ...
Hace 1 día · In a remarkable feat, a team of scientists has taken the world’s first X-ray signature of just one atom. This stunning achievement could revolutionize the way scientists detect materials. The research team was led by Saw Wai Hla, Professor of Physics at Ohio University and scientist at Argonne National Laboratory.
Hace 2 días · Atom sigue con su apuesta en el Trail Running con el lanzamiento de una nueva zapatilla, las Atom K4.Este modelo se sitúa como la zapatilla más técnica que han hecho hasta el momento la casa Riojana. En primer lugar, decir que Atom ha cogido para este modelo el nombre de la decimotercera montaña más alta del mundo, el K4, también conocido como Gasherbrum II.
Hace 1 día · The neutron is a subatomic particle, symbol n or n 0, which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton.Protons and neutrons constitute the nuclei of atoms.Since protons and neutrons behave similarly within the nucleus, they are both referred to as nucleons.Nucleons have a mass of approximately one atomic mass unit, or dalton (symbol: Da).
