Effect of Process Parameters on Friction Properties of AISI 304 Steel Sheet during Strip Drawing Test

open access: yessteel research international, EarlyView.
This study investigates how drawing process parameters affect the tribological behavior of AISI 304 steel sheet. Under lubricated conditions, increasing normal force, drawing speed, and countersamples roughness reduces the coefficient of friction by up to 21%.

DOSSIER FOTOGRAFICO: Dall’oro verde all’oro nero. La Sicilia di Paolo La Rosa

open access: yesDiacronie. Studi di Storia Contemporanea, 2011
Nel 2006 ha conseguito la Laurea triennale in «Storia contemporanea» presso l’Università di Bologna; nel 2008 ha ottenuto un doppio titolo di Laurea Specialistica in «Storia d’Europa» e di Master 2 «Histoire et civilisations comparées» presso l’Università di Bologna e l’Université Paris VII – Denis Diderot. Tra il 2009 e il 2011 è stata borsista presso l’Ecole Française de Rome e visiting student presso l’University of Malta. Nel 2013 ha conseguito un dottorato di ricerca in cotutela in «Scienze storiche» presso l’Università di Padova e in «Histoire» presso l’Université de Nice Sophia-Antipolis, svolgendo una ricerca sull’irredentismo fascista in Corsica e a Malta negli anni tra le due guerre. Attualmente è assegnista di ricerca presso l’Università Ca’ Foscari di Venezia dove sta conducendo uno studio sulle politiche identitarie e sull’immaginario insulare nelle isole del Mediterraneo e del Baltico durante il XX e il XXI secolo. È autrice del libro Corsica fatal, Malta baluardo di romanità. L’irredentismo fascista nel Mare nostrum (1922-1942) (Firenze, Le Monnier, 2015).

Influence of Heat Treatment Temperature on Crevice and Pitting Corrosion of UNS S32205 Duplex Stainless Steel

open access: yessteel research international, EarlyView.
Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

Novel Bio‐Based Polyurethane Elastomers Customizable for Orthopedic Devices: Toughness, Rapid Degradability, and Safety

open access: yesSusMat, EarlyView.
ABSTRACT Given the increasing global demand for sustainable materials and growing concerns over the depletion of petrochemical resources, we report the synthesis of an amorphous bio‐derived polyester diol, and this diol was polymerized with various isocyanates and butanediol, yielding a novel series of bio‐based polyurethane elastomers (BPUEs). Notably,

Platinum–Copper Dual‐Atom Catalyst Enables the Selective Electro‐Oxidation of 5‐Hydroxymethylfurfural to 2,5‐Furandicarboxylic Acid

open access: yesSusMat, EarlyView.
A platinum–copper dual‐atom catalyst was developed for the selective electrooxidation of 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA) in alkaline solution, achieving a FDCA yield of 97.4% at 1.42 V. DFT and experimental analyses reveal that Pt atoms enrich the OH* coverage, driving deep oxidation of HMF on adjacent Cu atoms ...

Improved DC Properties of Polypropylene HVDC Cable Insulation by Grafting and Blending Combined Modification

open access: yesHigh Voltage, EarlyView.
ABSTRACT In order to meet the needs of mechanical properties of cable insulation, polypropylene (PP) needs to be blended with low modulus materials to achieve toughening and softening. However, the compatibility between two or more resins can significantly affect the electrical properties of the composites.
