Comparing energy and Randic energy

Macedonian Journal of Chemistry and Chemical Engineering, 2013
The recently conceived Randić energy (RE) is examined, and its relation to the (earlier much studied) total π-electron energy (E) is investigated. Within classes of molecular graphs, there exists a relatively good (increasing) linear correlation between RE and E.

‘Oxygen Bound to Magnesium’ as High Voltage Redox Center Causes Sloping of the Potential Profile in Mg‐Doped Layered Oxides for Na‐Ion Batteries

Advanced Functional Materials, EarlyView.
Na‐ion batteries ‐ Impact of doping on the oxygen redox: The sloping potential of NaMg0.1Ni0.4Mn0.5O2 above 4.0 V is caused by a new redox center (arising from the ‘O bound to Mg’), having a higher potential but being more irreversible compared to the ‘O bound to Ni’.

L’accès du plus grand nombre aux services essentiels ne se fera pas sans une implication du secteur privé et sans une tarification adéquate de ces services

Field Actions Science Reports, 2012
La couverture, via le secteur privé, des besoins en services de base (eau, énergie, services financiers, logement,..) des populations des pays en développement est une nécessité si l’on veut essayer de faire reculer la pauvreté.

Intrabandgap States Engineering in Functionalized Nanodiamond to Generate Solvated Electrons for Photocatalysis Under Solar Illumination

Advanced Functional Materials, EarlyView.
The negative electron affinity of diamond allows to emit highly reductive electrons. By introducing intra‐bandgap states and an optimized electron transfer mechanism by surface functionalization with Ru(bpy)3, the formation of solvated electrons is achieved upon solar irradiation.

Facet‐Engineered S‐Scheme Heterostructure With Enhanced Active Sites for Efficient Photocatalytic Degradation of Organic Contaminants

Advanced Functional Materials, EarlyView.
The facet‐engineered ZnO/Zn3In2S6 heterostructure, dominated by {001} plane coupling, exposes abundant unsaturated Zn sites with elongated Zn─O bonds, directing photoexcited charge carriers along an S‐scheme pathway and suppressing recombination. Enhanced interfacial Zn adsorption toward bisphenol A and methylene blue further synergistically promotes ...
