In the CoMSIA model, steric, electrostatic, hydrophobic and hydrogen bond donating factors were correlated to the activity and later the favorable and unfavorable regions of interaction were obtained.
      
tripos standard, hydrogen bonding, parabolic indicator in the case of CoMFA and steric, electrostatic, donor, acceptor, hydrophobic, donor and acceptor, steric and electrostatic in the case of CoMSIA.
      
Flavonoid antioxidants act as scavengers of free radicals by rapid donation of a hydrogen atom.
      
In addition, electrostatic, hydrogen-bonding, and dipole-dipole interactions are responsible for the above separations, which improve the selectivity of DNB for solutes.
      
Both metalation reaction with n-butyllithium and hydrochlorination reaction with dry hydrogen chloride selectively and quantitatively occurred at the pendant reactive sites, generating polymeric benzyllithium and 1-chloroethylbenzene species.
      
Synthesis, characterization and hydrogen storage capacity of MS2 (M = Mo, Ti) nanotubes
      
The structure, morphology and hydrogen-storage capacity of MS2 (M = Mo, Ti) nanotubes prepared by different experimental methods were studied.
      
In comparison, TiS2 nanotubes can store 2.5 wt% hydrogen under the hydrogen pressure of 4 MPa and 25°C.
      
The results show that MS2 compound nanotubes are promising materials for hydrogen storage.
      
For example, in water, PCL and PAA formed core-shell nanospheres due to interpolymer hydrogen bonding.
      
Their catalytic activity in the oxidation of cyclohexanol and benzyl alcohol was investigated with only aqueous 30% hydrogen peroxide.
      
From the FTIR spectra, it was found that during the transition process of polyamide 618, the intensity of the intra-sheet hydrogen bonds becomes weak.
      
The analytical results indicate that the water introduced into the dry gel first combines with the hydrophilic groups of the network chains through hydrogen bond forming non-freezable water.
      
Electrochemical behavior of hydrogen peroxide sensor based on new methylene blue as mediator
      
A novel amperometric hydrogen peroxide sensor was proposed by co-immobilizing new methylene blue (NMB) and Horseradish peroxidase (HRP) on glassy carbon electrode through covalent binding.
      
The experiments showed NMB could effectively transfer electrons between hydrogen peroxide and glassy carbon electrode.
      
Hydrogen atom in strong magnetic field: A high accurate calculation in spheroidal coordinates
      
A B-spline-type basis set method for the calculation of hydrogen atom in strong magnetic fields in the frame of spheroidal coordinates has been introduced.
      
High accurate energy levels of hydrogen in the magnetic field, with strength ranging from 0 to 1000 a.u., have been obtained.
      
The method has also been applied to the calculation of hydrogen Rydberg states in laboratory magnetic fields.
