Determination of Thermal Characteristics of Fe-C Cast Iron Using Hot Disk Method

Tehnički Glasnik
This paper explores the influence of graphite shape, type, and dimensions on the thermal characteristics of Fe-C cast iron. Test samples were prepared from blocks of grey and nodular cast iron, specifically examining castings with D and A types of ...

Modification of the Surface Layer of Grey Cast Iron by Laser Heat Treatment

Lubricants
This paper presents possible modifications to the properties of grey cast iron by laser heat treatment. These modifications are analyzed especially with regard to wear properties as a result of graphite content, which is a well-known solid lubricant ...

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

A Topology Optimization Framework for the Inverse Design of Nonlinear Mechanical Metamaterials

Advanced Engineering Materials, Volume 28, Issue 9, 6 May 2026.
This work uses topology optimization to design unit cells for mechanical metamaterials with a prescribed nonlinear stress–strain response. The framework adds contact and postbuckling modeling to synthesize microstructures for three highly nonlinear responses, including pseudoductile behavior, monostable with snap‐through buckling, and bistable ...

Hydrophobic Eutectic Solvent‐Engineered Membranes for Highly Permeable, Selective, and Antifouling Pharmaceutical Removal from Municipal Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
Single‐step incorporation of a hydrophobic deep eutectic solvent (HDES) into polyethersulfone ultrafiltration membranes via non‐solvent induced phase separation creates selective, antifouling membranes for pharmaceutical removal. The HDES nanodomains enhance permeability, electrostatic interactions, and adsorption affinity, enabling efficient and ...

Radiolysis and Fe‐Biotite Alteration: Questioning the Origin of H2‐Bearing Fluid Inclusions in the Yorke Peninsula Granites, South Australia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Multiple drillings in the Yorke Peninsula, South Australia, recently confirmed the presence of natural hydrogen (H2) in shallow sedimentary units. While radiolysis and Fe‐oxidation in the basement are potential generation mechanisms, their respective contributions remain unconstrained.
