Sub-millimeter nuclear medical imaging with high sensitivity in positron emission tomography using beta-gamma coincidences

open access: yes, 2014
We present a nuclear medical imaging technique, employing triple-gamma trajectory intersections from beta^+ - gamma coincidences, able to reach sub-millimeter spatial resolution in 3 dimensions with a reduced requirement of reconstructed intersections ...

A Late Pleistocene‐Holocene Record of Tropical Monsoon Climate from Groundwater Noble Gases and Isotopes in the Leizhou Peninsula, Southern China

open access: yesGeophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Groundwater from the Leizhou Peninsula in tropical South China provides one of the first noble‐gas based paleoclimate reconstructions from the East Asian monsoon region. Radiocarbon dating establishes a robust chronology spanning the Late Pleistocene to the Holocene. Noble gas temperatures reveal a minimum glacial‐to‐Holocene warming of ∼5°C–6°

Parent body thermal metamorphism of enstatite chondrites: Disentangling the effects of shock melting

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 12, Page 2828-2863, December 2025.
Abstract Enstatite chondrites (ECs) formed on at least two parent bodies, EH and EL. After the accretion of the EC parent bodies, EC material was subjected to varying degrees of parent body thermal metamorphism (measured by petrologic types 3–6), due to heat released by radioactive isotope decay.

Matera: A not so ordinary H5 chondrite breccia with very low density and high porosity

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 9, Page 2125-2148, September 2025.
Abstract On the evening of February 14, 2023, at 17:58 UT, a fireball was detected by three cameras of the Italian PRISMA network (FRIPON network). The first samples of the Matera meteorite, collected 3 days after the fall, lay on the balcony of a private home.

Scalability study of solid xenon

open access: yes, 2015
We report a demonstration of the scalability of optically transparent xenon in the solid phase for use as a particle detector above a kilogram scale. We employed a cryostat cooled by liquid nitrogen combined with a xenon purification and chiller system ...

A critical review of lanthanum and lanthanum‐based materials: synthesis, applications, and challenges

open access: yesRare Metals, Volume 44, Issue 8, Page 5201-5232, August 2025.
Graphical abstract AbstractDevice fabrication is increasing with the importance of functional materials for industrial applications. To fulfil increasing demands, rare earth element‐based materials have become important. In particular, lanthanum (La) and La‐based materials have garnered attention in recent years due to their versatile properties and ...

Technetium ‐ The Unknown Center of the Periodic Table

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 9, March 21, 2025.
It took 78 years from Mendeleev's proposal of an existence of “eka‐manganese” (1869) until it was finally named as technetium in 1947. Another 78 years have passed since then. A good occasion to pinpoint what we know and what we still don't know of this element in the center of the periodic table.

The EXO-200 detector, part I: Detector design and construction

open access: yes, 2012
EXO-200 is an experiment designed to search for double beta decay of $^{136}$Xe with a single-phase, liquid xenon detector. It uses an active mass of 110 kg of xenon enriched to 80.6% in the isotope 136 in an ultra-low background time projection chamber ...
