Surface modification effect on the repair bond strength of hybrid and non-hybrid ceramics
Background This study investigated the appropriate surface treatment protocols for repairing various hybrid and non-hybrid ceramics. Methods Ceramic samples with a thickness of 2 mm were prepared from two resin-hybrid CAD/CAM blocks (Vita Enamic (hybrid ...

Lu-Hf Isotopic Systematics and Its Applications for Geology
The Lu-Hf isotope system, coupled with the advent of multiple collector inductively coupled plasma source mass spectrometry, is now widely utilized as a tracer for geological processes. The paper presents a comprehensive review on the principles of the Lu-Hf isotopes, and its current and potential applications to both geochronology and petrogenesis ...

Basement Domains Recorded in the Zircon Geochemistry of the Northern Sierra Nevada Batholith
The northern Sierra Nevada batholith was emplaced into and across a series of accreted crustal belts that vary considerably in their ages and lithologies. Unlike batholithic segments to the south, the northern Sierra comprises smaller, spatially distinct

A combined procedure for separating Lu, Hf, Sm, Nd, and rare earth elements (REEs) from a single sample digest is presented. The procedure consists of the following five steps: (1) sample dissolution via sodium peroxide sintering; (2) separation of the high field strength elements from the REEs and other matrix elements by a HF-free anion-exchange ...
