The Massif Central as a Centre of Roman Brass Production? New Geochemical Data of the So‐Called Hemmoor Buckets

Archaeometry, EarlyView.
ABSTRACT New analytical data of the so‐called Hemmoor buckets, a group of brass vessels from the Roman period of the 2nd to 3rd century ad that are widespread throughout central and eastern Europe, show considerable similarities with the polymetallic Cévennes ore deposits in south‐eastern France in terms of their geochemical characteristics and lead ...

Solid-State Dispersions of Platinum in the SnO₂ and Fe₂O₃ Nanomaterials

Nanomaterials, 2021
The dispersion of platinum (Pt) on metal oxide supports is important for catalytic and gas sensing applications. In this work, we used mechanochemical dispersion and compatible Fe(II) acetate, Sn(II) acetate and Pt(II) acetylacetonate powders to better ...

Evolution of ecological indicators in the assessment of restoration of mining‐degraded riparian forests: a global bibliometric analysis (1990–2024)

Restoration Ecology, EarlyView.
Abstract Introduction The restoration of mining‐degraded riparian forests faces challenges due to structural, compositional, and functional impacts on these ecosystems. The demand for effective monitoring requires an understanding of how ecological indicators have been applied to assess post‐mining restoration success.

Age of hydrothermal processes in the central iberian zone (Spain) according TO U-Pb dating of cassiterite and apatite

Записки Горного института, 2017
Results of isotope-geochemical studies by PbLS step-leaching method of cassiterite from greisens located in Logrosán granite massif (Central Iberian Zone, Spain) and apatite from hydrothermal quartz-apatite vein on its exocontact indicate that in both ...

AVA‐MAPbI3 Cap‐and‐Root Islands on Mesoporous TiO2 Toward Neutral‐Color Semi‐Transparent Perovskite Solar Cells in Agrivoltaics

Advanced Energy and Sustainability Research, Volume 7, Issue 10, October 2026.
Photograph and scanning electron microscopy images of semi‐transparent AVA‐MAPbI3 cap‐and‐root islands in mesoporous TiO2. The spectrally neutral light transmitted by this architecture benefits agrivoltaic applications such as lettuce cultivation while maintaining a positive energy balance to meet annual greenhouse demands for lighting, irrigation, and

Tin-bearing magnetite with nanoscale Mg-Si defects: Evidence for the early stages of mineralization in a skarn system

Frontiers in Earth Science, 2023
Tin-bearing magnetite is reported from several types of magmatic-hydrothermal ore deposits. The question of whether tin is incorporated within solid solution, as Sn4+, or as nanoinclusions remains open, however.

Tin‐Modified MXene Composite Electrodes as Lithiophilic Hosts for Stable Lithium Metal Anodes

Batteries &Supercaps, Volume 9, Issue 9, September 2026.
A Sn‐modified Ti3C2Tx MXene host was developed to regulate lithium metal deposition by combining a lamellar porous architecture with Sn‐derived lithiophilic sites. Compared with bare Cu and pristine MXene, Sn@MX promotes more uniform and confined Li growth, suppresses dendritic deposition, and enables stable stripping/plating for over 120 cycles in ...

Cryptic Superfine Placer Gold Populations, Round Hill Mine, Southern New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Superfine (50–<1 µm) detrital gold and platinum group mineral (PGM) particles at the Round Hill mine near Foveaux Strait were locally derived (<20 km) from as‐yet undefined basement sources. This superfine component contrasts with the dominant coarser (typically >100 µm) gold and PGM particles at the mine that have been transported for >100 km in ...
