Microstructural Evolution and Mechanical Performance of Plasma‐Assisted Hybrid Friction Stir Welded Dissimilar Aluminum–Copper Joints

open access: yesAdvanced Engineering Materials, EarlyView.
Plasma‐assisted hybrid friction stir welding of dissimilar AlCu joints employs localized plasma preheating to balance heat input and enhance plastic flow. The optimized process reduces axial force by up to 35%, refines the microstructure, and achieves ≈96% joint efficiency.

Biomimetic coating-free surfaces for long-term entrapment of air under wetting liquids

open access: yesNature Communications, 2018
Trapping air at the solid–liquid interface is a promising strategy for reducing frictional drag and desalting water, although it has thus far remained unachievable without perfluorinated coatings.

Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6

open access: yesAdvanced Engineering Materials, EarlyView.
The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).

Gothic Discourse in Jeffrey Eugenides’s 'The Virgin Suicides' – Challenging Suburban Uniformity and (Re)Imagining “The Other”

open access: yesLinguaculture, 2018
This paper argues that Jeffrey Eugenides, in his début novel, The Virgin Suicides, first questions and then challenges ‘the homeliness’ of the American suburbia by adopting an unsettling gothic discourse and by creating gothic subjects (the Lisbons ...

Mechanically Deposited Wear‐Resistant Amorphous Zr55Cu30Al10Ni5 Coatings

open access: yesAdvanced Engineering Materials, EarlyView.
Mechanically deposited from glassy ribbons, the Zr55Cu30Al10Ni5 amorphous coating formed a hard, continuous layer on AISI 1010 steel, tripling substrate hardness, lowering friction, and reducing wear. Despite its rough surface, it showed friction and wear behavior comparable to the crystalline alloy, highlighting its strong potential as a durable ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Moduli Entrapment with Primordial Black Holes

open access: yes, 2004
We argue that primordial black holes in the early universe can provide an efficient resolution of the Brustein-Steinhardt moduli overshoot problem in string cosmology.

Engineering Deformation and Failure in Diamond Triply Periodic Minimal Surface Lattices via 3D Wall‐Thickness Grading

open access: yesAdvanced Engineering Materials, EarlyView.
The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.
