J 2 is one of the 26 Sporadic groups and is also called Hall–Janko–Wales group.In 1969 Zvonimir Janko predicted J 2 as one of two new simple groups having 2 1+4:A 5 as a centralizer of an involution (the other is the Janko group J3).
Jacobus van 't Hoff (1852–1911), an influential theoretical chemist and the first winner of the Nobel Prize in Chemistry.. Theoretical chemistry is the branch of chemistry which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry: for example, the concepts of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular ...
In particular the theory of random graphs has been used as a justification for self-organization as a general principle of complex systems. In the field of multi-agent systems , understanding how to engineer systems that are capable of presenting self-organized behavior is an active research area. [ 45 ]
The J1–J2 model is a quantum spin model like the Heisenberg model but also includes a term for the interaction between next-nearest neighbor spins. Hamiltonian [ edit ]
The cage effect can be quantitatively described as the cage recombination efficiency F c where: = / (+) [9] Here F c is defined as the ratio of the rate constant for cage recombination (k c) to the sum of the rate constants for all cage processes. [9]
Alfred Werner (12 December 1866 – 15 November 1919) was a Swiss chemist who was a student at ETH Zurich and a professor at the University of Zurich.He won the Nobel Prize in Chemistry in 1913 for proposing the octahedral configuration of transition metal complexes.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
In chemistry, the Sabatier principle is a qualitative concept in heterogeneous catalysis named after the French chemist Paul Sabatier. It states that the interactions between the catalyst and the reactants should be "just right"; that is, neither too strong nor too weak. If the interaction is too weak, the molecule will fail to bind to the ...
