aCompare the magnitude of intermolecular forces of H2O and O2:[translate] aThe hydrogen bond is a weak bond,but than van der Waals force is strong.H2O has two hydrogen atoms.The oxygen atom has two lone pairs of electrons, which is easy to other hydrogen atoms to form hydrogen bonds, so...
The spectroscopic features of protonated water species in dilute acid solutions have been long sought after for understanding the microscopic behavior of the proton in water with gas-phase water clusters H+(H2O)n extensively studied as bottom-up model systems. We present a new protocol for the ca...
electrons scattering from the C atoms to the water molecule, however, although it is very weak, being 1 per cent of the magnitude of the maximum current flowing between the C bonds. As can be seen, all the positive currents first flow onto the O atom and then flow out of the water ...
1b). Each Mo(V) atom appears similarly bound through a single Mo–O–W bridge, wherein the bound oxygen atom of the Mo coordination sphere occupies an equatorial position. Besides, the coordination sphere of the Mo(V) atoms is filled by two aquo ligands to give the typical {MoS2O4} ...

Table 6. Calculated adsorption energies of *H + *X on Al (111) surface (Eads), the bond length between halogen and Al atoms (d), and the charge transfer from Al (111) to halogen ions. It appears that AlX (X = F, Cl, Br, and I) produced in situ during ball milling meets ...
Tiberio Bardi contributed to the mineralogical rediscovery of the small Cu ore deposits of Cretaio, where he first collected the type material of tiberiobardiite. The mineral and its name have been approved by the IMA CNMNC, under the number 2016-096. The holotype specimen is deposited in th...
Today Easter still serves as a traditional time for baptisms in a number of Christian denominations. Easter Water Customs In addition to baptism, a number of other water-related rites and customs take place at Easter time. These practices also draw on established Christian and folk symbolism ...
The change of conductance of single-molecule junction in response to various external stimuli is the fundamental mechanism for the single-molecule electronic devices with multiple functionalities. We propose the concept that the conductance of molecular
