Van der Waals forces are yet another type of chemical bond. They are named in honor of the Dutch physicist Johannes Diderik van der Waals (1837–1923), who investigated the weak nonchemical bond forces between molecules. Such forces exist between particles that appear to be electrically neutral...
of oxygen defects engineering, Mefford et al. [43] pointed out that more oxygen vacancies in La1−xSrxCoO3−δperovskite ensured stronger covalency of Co-O bond, which provided higher activity towards OER. Zhu et al. [44] revealled that the free energy of the rate determining step in...

Oxygen-terminated type IIa (OT-IIa) diamond with oxygen suspended in the form of a ketone bond (C=O) was synthesized via acid treatment. The Fermi level at 3.23 eV below the conduction band minimum for the OT-IIa diamond surface was measured experimentally, while that at 0.97 eV for the...
Interaction of hydrocarbons with gaseous oxygen may be slow or fast, depending on conditions and substrate, but peroxidic products are always involved, and the rate of formation is highest at a C-H link adjacent to an aromatic ring or a double bond. Predictable conditions for explosion are ...
The electrical charge distribution of the atoms bonded in a molecule will define the polarity of the chemical bond between two atoms. Different types of molecules possess different polarity measures per the atoms' electronegativity. Highly polar...
athe two pairs of electrons of oxygen may be shared with one carbon alone forming a double bond, or with two separate carbons,or with one carbon and one hydrogen forming only single bonds 正在翻译,请等待... [translate]
