Basic personal values and the meaning of left‐right political orientations in 20 countries.
Summary (1 min read)
I. INTRODUCTION
- Hydrogen has attracted enormous research attention as a future energy resource.
- Recently, increasing attention has been paid to the carbon nanotube as a potential hydrogen storage medium due to its light mass density and high surface to volume ratio, as well as high degrees of reactivity between the carbon and hydrogen. [1] [2] [3] [4].
- One possible reason for this controversy is that SWCNTs can be either semiconductor or metal, depending on their diameters and helicities.
- The authors recently studied the adsorption of hydrogen atoms on BN nanotubes.
- The calculation results offer an explanation to the enhanced percentage of hydrogen chemisorption observed in the experiment.
II. MODEL SYSTEM AND COMPUTATIONAL METHODS
- The calculations were carried out by using the densityfunctional method implemented in the DMOL3 package.
- 24 Allelectron calculations were undertaken with the double numerical plus polarization ͑DNP͒ basis sets and the generalized-gradient approximation with the Perdew-Burke-Ernzerhof ͑PBE͒ functional.
- The real-space global cutoff radius of all atoms was set to be 5.5 Å. Spin-unrestricted DFT was used to obtain all the results reported below.
- The tube axis is set along the z direction.
- 26 Test calculations showed that increasing the k points has little change in the final results.
III. RESULTS AND DISCUSSION
- First, the authors examined the adsorption site on which a Pt atom can give rise to the highest adsorption energy on the single-walled ͑8, 0͒ BN nanotube.
- It turns out that the Pt atom is more stable on the BA site than on the BZ site.
- Here, the minus adsorption energy denotes exothermic adsorption.
- On the other hand, the authors also obtained a locally stable configuration such that the adsorbed hydrogen is in the atomic form.
- As the second hydrogen molecule approaches the Pt-doped BN nanotube, initially, it is physically adsorbed onto the Pt atom with small adsorption energy of −0.023 eV, as shown in Fig. 3͑a͒ .
IV. CONCLUSION
- The authors have presented DFT calculation results of hydrogen adsorption on the BN nanotube doped with a Pt atom or a Pt dimer ͑per supercell͒.
- The Pt atom tends to occupy the BA site of the BN nanotube.
- The doping of the Pt atom induces one unoccupied and five occupied impurity states within the band gap.
- Up to two hydrogen molecules can be chemically adsorbed on a single Pt atom supported by the BN nanotube, for which the average adsorption energy is −0.365 eV.
- With adsorption of a hydrogen molecule, the interaction between the Pt atom and the BN tube is weakened.

Q2. How much of the variance in political orientation was accounted for by values alone?
The socio-demographic variables alone accounted for an average of 6% of the variance in political orientation in the liberal countries.
Q3. What country did values explain more variance than socio-demographic variables?
In theliberal countries, values explained nearly twice as much variance in political orientation as socio-demographic variables did; in the post-communist countries values explained less than a third of the variance socio-demographic variables did with the exception of the Czech Republic.
Q4. In what countries did right self-placement covarate positively with tradition values?
In the post-communist countries, right self-placement covaried positively though notstrongly with tradition values in three of four countries.
Q5. What countries predicted political orientation better than values?
In sum, as hypothesized, values predicted political orientation more strongly thansocio-demographic variables in liberal countries but socio-demographic variables predicted more strongly in three of four post-communist countries.
Q6. What are the main reasons for the conflict in European liberal democracies?
The conflict in European liberal democracies between supporters of conservation and maintenance of the hierarchical social order and supporters of welfare and equality reflect these motivations.
Q7. What is the meaning of basic personal values in the liberal countries?
Basic personal values have indeed assumed a more important role than social structuralposition as determinants of political orientations in the liberal countries.
