Pliocene Te Aute limestones, New Zealand: Expanding concepts for cool-water shelf carbonates
Acceptance of a spectrum of warm- through cold-water shallow-marine carbonate facies has become of fundamental importance for correctly interpreting the origin and significance of all ancient platform limestones.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Oxidation of Carbon Monoxide on Strontium Ferrate
The subject of conversion of natural gas to electric energy in Solid Oxide Fuel Cells (SOFCs) and formation of C{sub 2}-products from methane in electrochemical reactors, has received considerable attention recently. In order to reduce the problem of coke formation in SOFCs, methane is co-fed with water, forming CO and H{sub 2}.

Impact of nitrogenous fertilizers on carbonate dissolution in small agricultural catchments: Implications for weathering CO2 uptake at regional and global scales [PDF]
The goal of this study was to highlight the occurrence of an additional proton-promoted weathering pathway of carbonate rocks in agricultural areas where N-fertilizers are extensively spread, and to estimate its consequences on riverine alkalinity and ...

Geochemical Mechanisms of Biomineralization from Analysis of Deep-Sea and Laboratory Cultured Corals [PDF]
The ocean is a major component of global heat transport and represents a large exchangeable reservoir of CO₂. The importance of these effects on climate can be quantified with records of ocean temperature, chemistry and dynamics spanning past climate ...

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs
