Performance of the Direct Current Electric Potential Difference (DCEPD) Method for Crack Extension Measurement in Fracture Mechanics Specimens Exhibiting Split Delaminations

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2963-2980, July 2026.
ABSTRACT This work investigates the performance of the direct current electric potential difference (DCEPD) method for measuring crack extension ( ∆a) during fracture toughness tests of ductile steels exhibiting delaminations perpendicular to the main crack plane, known as splits.

Thermally Activated Deformation Mechanisms in MgO Investigated via High Temperature Scanning Indentation

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT Magnesium oxide (MgO) serves as a model material for plastically deformable ceramics. In previous studies, it has mainly been investigated via uniaxial compression, with studies often focusing on a particular deformation mechanism and temperature range. In this work, the novel high temperature scanning indentation (HTSI) nanoindentation method

Distinct Distribution Patterns of Dissolved and Particulate Trace Metals in Surface Waters of the Amundsen Sea: From Polynya to Open Waters

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Trace metals regulate Southern Ocean productivity, but their cycling across Antarctic marginal‐sea gradients remains poorly constrained. We measured dissolved, labile particulate, and refractory particulate Mn, Fe, Ni, Cu, Zn, Cd, and Pb across the Amundsen Sea Polynya (ASP), sea‐ice zone (SIZ), and Oceanic Area (OA), alongside iron‐addition ...

Co(II), Cu(II), and Ni(II) Coordination Complexes: Synthesis, Characterization, Experimental, and Computational Study on Potential Antiplasmodial Activity

ChemMedChem, Volume 21, Issue 12, 26 June 2026.
Four isostructural complexes (C1–C4) derived from 2‐(tert‐butoxy)‐6‐(1H‐imidazol‐1‐yl)pyridine with axial halides exhibit octahedral trans M(L)4X2 geometries, confirmed by X‐ray diffraction. They feature a discrete 1,6M7−1 topology, identified using ToposPro analysis.

Thermal and Photocatalytic Conversion of CO2 to Ethanol: Advances in Catalyst Design, Challenges, and Opportunities

ChemSusChem, Volume 19, Issue 12, 26 June 2026.
This review examines thermo‐ and photocatalytic routes for converting CO2 to ethanol and analyzes how metal alloying, promoters, supports, surface structure, and semiconductor design govern catalyst activity, selectivity, and stability. It integrates mechanistic insights from experimental and theoretical studies and identifies the main challenges and ...
