Performance of Glass Fiber Composites With Plastic‐Waste Pyrolysis Char as Filler

Polymer Composites, EarlyView.
Valorisation of mixed plastic waste into carbonaceous char via pyrolysis, its integration as a microfiller in epoxy/E‐glass (GFRP) laminates, and characterisation to assess composite performance as a function of filler loading. ABSTRACT Plastic pyrolysis offers circular solutions for mixed plastic waste but leaves a carbonaceous char that is often ...

Synergistic approach of asteroid exploitation and planetary protection

, 2012
The asteroid and cometary impact hazard has long been recognised as an important issue requiring risk assessment and contingency planning. At the same time asteroids have also been acknowledged as possible sources of raw materials for future large-scale ...

A Review of Mechanical Reinforcement and Piezoresistive Self‐Sensing in Carbon Nanotube Fiber Composites

Polymer Composites, EarlyView.
PSPP‐TRL mapping of CNT‐modified CFRP literature, with four recurring confusions resolved and five scale‐up problems quantified. ABSTRACT Carbon nanotube‐modified fiber composites are often presented as a route to stronger, tougher, and self‐sensing structural materials.

Recycled Polyacrylonitrile Nanofiber Interleaves With Graphene Nanoplatelets for Adhesively Bonded Composite Joints: Lap‐Shear and Opening‐Mode Fracture Performance

Polymer Composites, EarlyView.
Textile‐waste Orlon is transformed into recycled PAN nanofiber interleaves for tougher and more damage‐resistant adhesive bondlines. ABSTRACT This study presents a sustainable toughening strategy for adhesively bonded CFRP joints by using electrospun polyacrylonitrile (PAN) nanofiber interleaves produced from virgin PAN (vPAN) and recycled PAN (rPAN ...

A Thoracic Mechanism of Mild Traumatic Brain Injury Due to Blast Pressure Waves

, 2008
The mechanisms by which blast pressure waves cause mild to moderate traumatic brain injury (mTBI) are an open question. Possibilities include acceleration of the head, direct passage of the blast wave via the cranium, and propagation of the blast wave to

Experimental and Modeling Investigation of Seawater Hydrolysis Effects on Aramid Fiber Rupture Behavior

Journal of Polymer Science, EarlyView.
Hydrolytic aging in seawater produces markedly different mechanical responses among commercial Aramid fibers. While some fibers exhibit progressive degradation, others maintain stable or even improved tensile behavior. Experimental yarn‐scale testing combined with mathematical degradation modeling and Arrhenius‐based lifetime prediction provides new ...

Failure after operative repair is higher for ballistic femoral neck fractures than for closed, blunt-injury fractures: a multicenter retrospective cohort study

Trauma Surgery & Acute Care Open
Introduction The purpose of this study was to describe the outcomes after operative repair of ballistic femoral neck fractures. To better highlight the devastating nature of these injuries, we compared a cohort of ballistic femoral neck fractures to a ...

Synthesis and Characterization of an Azido Nitrofurazanyl Ether: An Energy‐Rich Heterocyclic Plasticizer With a Low Glass Transition Temperature

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.

Tuning the Morphology of Self‐Assembled Nanopatterns on MgO(001) Surfaces by Sequential Broad‐Beam Ion Irradiation

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
A two‐step approach based on broad‐beam ion irradiation is demonstrated to produce fine‐tuned self‐assembled surface patterns on MgO(001). It shows an efficient route to modifying the crystalline MgO(001) surface topography in a controlled way, making use of its very specific behavior in terms of both the pattern morphology and patterning dynamics.
