Raman spectroscopy of the transition of α-gallium oxyhydroxide to β-gallium oxide nanorods [PDF]

, 2008
The thermo-Raman spectra of synthesised α-gallium oxyhydroxide nanorods proves the transition of α-gallium oxyhydroxide to β-gallium oxide nanorods occurs above 350 degrees Celsius but below 400 degrees Celsius.

Chelator‐Free Radiometal Labeling Inside Engineered Affibodies

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Affibodies are compact and robust three‑helix binders used in imaging and therapy. Engineering a triple‑cysteine motif into their core enables chelator‑free binding of important radiometals, like Bi(III), Pb(II), In(III), and Ga(III) with rapid uptake and exceptional stability.

Seasonal Variations in Aerosol Trace Element Source Contributions and Deposition Fluxes to the North Pacific Subtropical Gyre

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Trace elements deposited in the marine environment affect ocean biogeochemistry in numerous, complex ways. This study quantifies seasonal aerosol trace element (TE) fluxes and evaluates their variability and potential sources over a 2‐year period in the North Pacific subtropical gyre (NPSG). We established the Hawaii Aerosol Time Series (HATS),

Advances in modified gallium lanthanum sulphide (Ga:La:S) glass for optical fibre devices

, 2001
The advantages of gallium lanthanum sulphide (GLS) based glass over other competing glasses for active and infrared applications are evident through its low-phonon energy, high rare-earth solubility, high transition temperature and non-toxicity.

Quantifying Natural Hydrogen‐Helium Sources and Dynamic Accumulation in Global Sedimentary Basins

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract Despite the scientific and economic importance of hydrogen and helium, their crustal budgets remain poorly quantified. This study systematically assesses the accumulation of natural hydrogen and helium in global sedimentary basins by integrating predictive models for both gases with H2/He ratios.

Discovering Shared Design Heritage for Semiconductor‐Based Gamma‐Ray Spectrometers: From CdTe to Metal Halide Perovskites

Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
Decades of CdTe and CdZnTe gamma‐ray spectrometer development define core design principles for room‐temperature semiconductor detectors. This Review highlights how metal halide perovskites rapidly assimilate these principles, particularly through defect and compositional engineering strategies that establish favorable spectroscopic conditions for ...

Brine Pool Microbes Enrich Metalliferous Sediments in Salt Giant Basins

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract We report the discovery of an extinct deep‐sea brine pool in the Red Sea's Hume Deep, providing evidence that rift‐shoulder pools are ephemeral on millennial timescales, and that the microbially‐enriched metalliferous deposits produced during the pool's active phase persist into the stratigraphic record.

Petrogenesis and Tectonic Implication of the Newly Identified Rhyacian and Orosirian Orthogneisses in the Northwestern Part of the Gyeonggi Massif (Soyeonpyeongdo and Ganghwado Areas), South Korea: Constrained From Whole‐Rock Geochemistry and Zircon U‐Pb‐Hf Isotopic Compositions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The Gyeonggi Massif is one of the major Precambrian basements in the Korean Peninsula where Paleoproterozoic orthogneiss and paragneiss were widely exposed. In this study, newly identified Rhyacian to Orosirian meta‐igneous rocks from the northwestern Gyeonggi Massif (Soyeonpyeongdo and Ganghwado areas) were investigated to elucidate their ...

Diverse DTPA‐chelated lanthanides with relevance for nuclear medicine bound to an engineered lipocalin reveal conserved ligand geometry

Acta Crystallographica Section F, Volume 82, Issue 9, Page 301-311, September 2026.
Structural and binding studies of the engineered lipocalin CL31d towards the chelate complexes of 11 different lanthanide and main‐group metal(III) ions, whose radioisotopes are useful for nuclear medicine, with a functionalized DTPA revealed a surprisingly broad tolerance towards varying ionic radii, thus enabling flexible radionuclide‐targeting ...
