A new tool to elucidate chemical bonding in bulk solids, surfaces and nanostructures has been developed. Solid State Adaptive Natural Density Partitioning (SSAdNDP) is a method to interpret chemical bonding in terms of classical lone pairs and two-center bonds, as well as multi-center delocalized bonds. Here we extend the domain of AdNDP to bulk materials and interfaces, yielding SSAdNDP. We de...

For more than 20 years, the OECD Nuclear Energy Agency (NEA) has been conducting international studies related to the partitioning and transmutation (P&T) of nuclear waste, including physics, chemistry and material issues, as well as fuel cycle and radioactive waste management strategies. The information exchange meetings on actinide and fission product partitioning and transmutation, organised...

Some substances are mixtures of very large number of constituents which vary widely in their properties, and thus also in terms of their environmental fate and the hazard that they may pose to humans and the environment. Examples of such substances include industrial chemicals such as the chlorinated paraffins, technical pesticides such as toxaphene, and unintended combustion side products, suc...

Carbon sequestration in terrestrial vegetation and soils is a poorly understood process, but ultimately represents a summation of biological activities including the initial incorporation of atmospheric CO2 into plant carbohydrates through photosynthesis, carbon partitioning to chemical forms of organic matter resistant to microbial decomposition and carbon allocation to recalcitrant pools of b...

Abstract It is well known that the classical recombination equation for two parent individuals equivalent to law of mass action a strongly reversible chemical reaction network, and can thus be reformulated as generalised gradient system. Here, this case an arbitrary number parents. Furthermore, structure backward-time partitioning process investigated.
