Computer Simulation of the Structure Formed During Solidification of Cast Iron

, 1984
By combining heat extraction laws with kinetic growth laws, the solidification process of nodular, grey and white cast iron have been calculated. The risk for formation of white structure during solidification of grey and nodular cast iron was calculated.

Influencia del cobre en la transformación Gamma-Alfa en la fundición gris y nodular-templabilidad [PDF]

, 2011
This research refers to the grey iron lamellar graphite casting and nodular cast iron casting. Both contain variable percentages of copper to a maximum of 4%, cooled in sand molds in which the apparent solubility of copper is limited, to obtain wear ...

The feasibility of low-G grey solidification of nodular iron in the F-104 experimental furnace package [PDF]

, 1983
The rationale for low-g experiments with cast iron and the need for solidification in the grey form during these experiments are reviewed. The factors which determine whether an iron melt will solidify grey or white are discussed.

Earthworms With Low Dose n‐MoS2 Improve Soybean Yield and Quality by Reconfiguring Rhizosphere Chemistry and Strengthening Nitrogen Fixation

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Nano‐enabled fertilizers can enhance biological nitrogen fixation (BNF) and yield in legumes; yet, their interactions with earthworms remain poorly understood. Herein, we performed a 120‐day greenhouse experiment applying low‐dose n‐MoS2 at 10 mg kg−1 with earthworms to evaluate interactive effects on soybean yield and underlying mechanisms ...

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 ...

Stratified Pit Features at the Presbytère de l'Ancienne‐Lorette (CeEu‐11) and the Fort Odanak (CaFe‐7) Sites in Québec, Canada: A Comparative Geoarchaeological Analysis

Geoarchaeology, Volume 41, Issue 3, May/June 2026.
ABSTRACT A geoarcheological study of two large, stratified Indigenous pit features discovered at two Jesuit mission sites in Québec (Canada) was carried out to offer a detailed documentation of their contents and better understand their use over time. One of the pits is a 17th c.
