Geology, geochemistry and fluid inclusion of Qarachilar Cu-Mo-Au quartz veins, northeast of Kharvana, East Azerbaijan

Journal of Economic Geology, 2018
Introduction The Qarachilar Cu-Mo-Au occurrence is located in the Arasbaran ore zone (AZ), NW Iran, some 70 km north of Tabriz. The AZ is characterized by occurrence of different types of mineralization and hosts many Cu-Mo porphyry (PCD), Cu skarn, and

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

Journal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

ST Quartz Acoustic Wave Sensors with Sectional Guiding Layers [PDF]

, 2008
We report the effect of removing a section of guiding layer from the propagation paths of ST-quartz Love wave sensors; this offers the ease of fabrication of a polymer guiding layer whilst retaining the native surface of the quartz which may then be used

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Protein Corona Engineering of Lipid Nanoparticles Enables Efficient Functional Gene Silencing in the Liver

Small, EarlyView.
By shaping the protein corona, lipid composition directs LNP tropism and enables the preferential delivery of a TIMP1‐targeting siRNA to liver macrophages. In a murine model of primary biliary cholangitis, this strategy promoted macrophage reprogramming and attenuated liver fibrosis.
