Which Oxide for Low-Emissivity Glasses? First-Principles Modeling of Silver Adhesion

Density functional theory (DFT) calculations were performed to assess the work of adhesion of silver layers deposited on metal oxide surfaces differing by their chemical nature (ZnO, TiO₂, SnO₂, and ZrO₂) and their crystallographic face. The calculated work of adhesion values range from ∼0 to 3 J m^–2 and are shown to originate from the interplay between ionic (associated with charge transfer at the interface) and covalent (as probed by atomic bond orders between silver and the metal oxide atoms) interactions. The results are discussed in the context of the design of silver/metal oxide interfaces for low-emissivity glasses

Dopamine–endocannabinoid interactions mediate spike-timing-dependent potentiation in the striatum

Dopamine tightly regulates plasticity at corticostriatal synapses. Here, the authors report that endocannabinoid dependent LTP induced with few spikes in the striatum is impaired in a rodent model of Parkinson’s disease, requires dopamine through presynaptic D2 receptors located on corticostriatal inputs
