Dynamic and thermodynamic properties of the generalized diamond chain model for azurite [PDF]
Journal of Physics: Condensed Matter, 2011 The natural mineral azurite Cu3(CO3)2(OH)2 is an interesting spin-1/2 quantum antiferromagnet. Recently, a generalised diamond chain model has been established as a good description of the magnetic properties of azurite with parameters placing it in a highly frustrated parameter regime.

Clinical and Translational Medicine, Volume 15, Issue 3, March 2025.In unilateral ischaemia–reperfusion injury (UIRI), Trem2 expression is upregulated by hypoxia via HIF‐1α in macrophages, and the activation of Trem2 enhances phagocytosis and reduces cytokine production through the PI3K‐AKT pathway in macrophages. An adoptive cell therapy using Triggering Receptor Expressed on Myeloid Cells 2 (TREM2)‐overexpressing ...

Ant‐Nest Corrosion in Copper Pipes Triggered by Ethylene Vinyl Acetate‐Based Adhesive
Materials and Corrosion, Volume 76, Issue 2, Page 316-325, February 2025.Microscopic pinholes caused leaks in the copper pipes of a refrigerator condenser; detailed morphological and chemical analyses identified ant‐nest corrosion as the failure mechanism, triggered by the use of hot‐melt glue containing ethylene vinyl acetate instead of a polyolefin‐based adhesive.
