First in situ Lu–Hf garnet date for a lithium–caesium–tantalum (LCT) pegmatite from the Kietyönmäki Li deposit, Somero–Tammela pegmatite region, SW Finland [PDF]

European Journal of Mineralogy
The in situ Lu–Hf geochronology of garnet, apatite, fluorite, and carbonate minerals is a fast-developing novel analytical method. It provides an alternative technique for age dating of accessory minerals in lithium–caesium–tantalum (LCT) rare-element ...

The time of eclogite formation in the ultrahigh pressure rocks of the Sulu terrane. Constraints from Lu-Hf garnet geochronology

, 2011
Eclogites from the main borehole of the Chinese Continental Scientific Drilling project yield highly precise Lu-Hf garnet-clinopyroxene ages of 216.9 +/- 1.2 Ma (four samples) and 220.5 +/- 2.7 Ma (one sample).

In situ Lu-Hf geochronology of garnet, apatite and xenotime by LA ICP MS/MS

, 2021
Available online 4 May 2021Lu–Hf geochronology is a powerful method to constrain the temporal evolution of geological systems. Traditional application of this dating method requires time-consuming chemical separation of the parent (¹⁷⁶Lu) and daughter ...

Review of Inorganic Separator Engineering for Next‐Generation Lithium–Sulfur Batteries: Compromise or Cornerstone?

Advanced Materials, EarlyView.
Inorganic compound‐modified separators transform lithium–sulfur batteries from passive polysulfide confinement to active reaction‐pathway regulation. A Practical Relevance Index (PRI)‐guided framework bridges interfacial chemistry of inorganic separators with practical constraints, establishing unified design principles for scalable, high‐energy ...

The Medicine Hat Block and the Early Paleoproterozoic Assembly of Western Laurentia

Geosciences, 2020
The accretion of the Wyoming, Hearne, and Superior Provinces to form the Archean core of western Laurentia occurred rapidly in the Paleoproterozoic. Missing from Hoffman’s (1988) original rapid aggregation model was the Medicine Hat block (MHB).

Band Alignment of Grafted Si/Ge0.89Sn0.11 Heterojunction Determined by X‐Ray Photoelectron Spectroscopy

Advanced Materials Interfaces, EarlyView.
ABSTRACT We investigate the band alignment of a monocrystalline grafted p‐type Si/Ge0.89Sn0.11 heterostructure using X‐ray photoelectron spectroscopy (XPS). The bandgap of the Ge0.89Sn0.11 epilayer of 0.50 eV was first determined and cross‐verified using photoluminescence spectroscopy, infrared transmission, and theoretical calculation.

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

Advanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in
