[Bibliometric indicators of nephrology journals: strengths and weaknesses].

Scientific journals are an important communication tool through which authors, publishers, editors, readers, librarians support the circulation of information. How do I select the journal to submit for publication? How can my research have the widest circulation? How can I make my article and my scientific activities to be positively considered by assessment boards? These are some of the main questions that arise when an author chooses to write an article. The research evaluation can be based on qualitative indicators such as the peer review and/or quantities of a not bibliometric or bibliometric type, such as the Impact Factor or SCImago Journal Rank indicator.

Activation and splitting of carbon dioxide on the surface of an inorganic electride material.

Activation of carbon dioxide is the most important step in its conversion into valuable chemicals. Surfaces of stable oxide with a low work function may be promising for this purpose. Here we report that the surfaces of the inorganic electride [Ca24Al28O64](4+)(e(-))4 activate and split carbon dioxide at room temperature.

Flexibility and swing effect on the adsorption of energy-related gases on ZIF-8: combined experimental and simulation study.

ZIF-8, a prototypical zeolitic porous coordination polymer, prepared via the self-assembly of tetrahedral atoms (e.g. Zn and Co) and organic imidazolate linkers, presents large cavities which are interconnected by narrow windows that allow, in principle, molecular sieving.

Impact of ligands on CO(2) adsorption in metal-organic frameworks: First principles study of the interaction of CO(2) with functionalized benzenes. II. Effect of polar and acidic substituents.

Intermolecular interactions between the CO(2) molecule and a range of functionalized aromatic molecules have been investigated using density functional theory. The work is directed toward the design of linker molecules which could form part of new metal-organic framework materials with enhanced affinity for CO(2) adsorption at low pressure. Here, the focus was on the effect of introducing polar side groups, and therefore functionalized benzenes containing -NO(2), -NH(2), -OH, -SO(3)H, and -COOH substituents were considered.

Impact of ligands on CO2 adsorption in metal-organic frameworks: first principles study of the interaction of CO2 with functionalized benzenes. I. Inductive effects on the aromatic ring.

Intermolecular interactions between the CO(2) molecule and a range of functionalized aromatic molecules have been investigated using density functional theory. The work is directed toward the design of linker molecules which could form part of new metal-organic framework materials with enhanced affinity for CO(2) adsorption at low pressure. Two classes of substituted benzene molecules were considered: (i) with halogen substituents (tetrafluoro-, chloro-, bromo-, and dibromobenzene) and (ii) with methyl substituents (mono-, di-, and tetramethylbenzene).

Solid phases of cyclopentane: combined experimental and simulation study.

The phase diagram of cyclopentane has been studied by powder neutron diffraction, providing diffraction patterns for phases I, II, and III, over a range of temperatures and pressures. The putative phase IV was not observed. The structure of the ordered phase III has been solved by single-crystal diffraction.

Morphological variability of pterion in the human skull.

The pterion is one of the most interesting bone meeting points in craniofacial osteology and its complex morphology derives from the fact that is the contact point of the facial skeletal elements, skull base and calvarium. Knowledge of its peculiar morphology is mandatory for the pterional approach used in microsurgery and surgery. The Authors studied 506 adult, human skulls where the pterion was accurately reconstructed on polyethylene sheets.
