Investigating skyrmion stability and core polarity reversal in NdMnGe.

We present a study on nanoscale skyrmionic spin textures in [Formula: see text], a rare-earth complex noncollinear ferromagnet. We confirm, using X-ray microscopy, that [Formula: see text] can host lattices of metastable skyrmion bubbles at room temperature in the absence of a magnetic field, after applying a suitable field cooling protocol. The skyrmion bubbles are robust against temperature changes from room temperature to 330 K.

Model structures of molten salt-promoted MgO to probe the mechanism of MgCO formation during CO capture at a solid-liquid interface.

MgO is a promising solid oxide-based sorbent to capture anthropogenic CO emissions due to its high theoretical gravimetric CO uptake and its abundance. When MgO is coated with alkali metal salts such as LiNO, NaNO, KNO, or their mixtures, the kinetics of the CO uptake reaction is significantly faster resulting in a 15 times higher CO uptake compared to bare MgO. However, the underlying mechanism that leads to this dramatic increase in the carbonation rate is still unclear.
