Thermal Degradation and Corrosion of Amines for CO2 Capture [PDF]

open access: yes, 2015
This report examines the thermal degradation and corrosion of various amine solvents as they apply to amine scrubbing for CO2 capture. Amines were placed in stainless steel cylinders and heated in convective ovens to simulate the stripping conditions ...

Complementary Surface Motifs Enhance NO3RR Performance in NiFe Alloys

open access: yesChemSusChem, Volume 19, Issue 1, January 2026.
Mixed NiFe surface sites promote critical nitrate reduction reaction steps relative to pure Ni(111) and Fe(110), leveraging multiple adjacent sites to enhance ammonium selectivity and overall Faradaic efficiency. Elemental first row transition metal electrocatalysts typically exhibit a tradeoff between Faradaic efficiency (FE) for the nitrate reduction

Gas Losses in Transformers—Influences and Consideration

open access: yesIEEE Access, 2023
Dissolved gas analysis (DGA) is frequently used for the condition assessment and monitoring of transformers. In the case of free-breathing transformers, gas losses may occur at the phase interface due to the chaotic molecular movement of the dissolved ...

Sc(III) Complexes of Pyclen Derivative Ligands as Probes for Hypoxia: Synthesis, Chemical Characterization, 44Sc‐Radiolabeling, and Preclinical Assessment

open access: yesChemistry – A European Journal, Volume 31, Issue 72, December 23, 2025.
Hypoxia‐sensitive nitroimidazole‐functionalized pyclen derivatives were successfully synthesized and radiolabeled with 44Sc(III), affording stable and inert scandium complexes. Remarkable Sc(III)‐binding capabilities of the PC2A‐mono(amide) platform enabled excellent radiolabeling performance, with ≥92–99% yields and ≥99% radiochemical purity. MicroPET

The Role of the Surface Energy of Tannin‐Based Adsorbent Materials on the Lead Removal Capacity in Contaminated Water

open access: yesChemistry–Methods, Volume 5, Issue 12, November 2025.
Sample with low concentration of surface groups presents low surface energy and in consequence low adsorption capacity independently of the specific surface area and micro and mesoporosity. In this work, inverse gas chromatography at infinite dilution was used to associate the surface properties (London component, acid and basic constants, and enthalpy)

Assessment of Space Weather Impacts on New Zealand Power Transformers Using Dissolved Gas Analysis

open access: yesSpace Weather
Space weather can have major impacts on electrical infrastructure. Multiple instances of transformer damage have been attributed to geomagnetic storms in recent decades, for example, the Hydro Quebec incident of 1989 and the November 2001 storm in New ...

Grey Hill Zircon – A Natural High 176Yb/177Hf Zircon Reference Material for LA‐MC‐ICP‐MS Hf Isotope Measurement

open access: yesGeostandards and Geoanalytical Research, Volume 49, Issue 4, Page 799-819, December 2025.
Key Points New natural high REE/Hf zircon reference material for in situ Hf isotopic measurement. Hf isotope ratio is independent of zircon textural domains. Stable Hf isotope ratio despite Pb and REE variability. Accurate measurements of Hf isotope ratios in zircon rely on adequate correction for isobaric interferences, which increase in complexity as
