Tension-tension fatigue behavior of hybrid glass/carbon and carbon/carbon composites

Anastasios Vassilopoulos, José Manuel de Sena Cruz

This work investigates the quasi-static, low-cycle and fatigue behavior of hybrid glass/ultra-high modulus carbon (GC) and low modulus/ /high modulus carbon (CC) fiber composites. These pseudo-ductile unidirectional interlayer hybrids are a new type of com ...

Optical gap and fundamental gap of oligoynes and carbyne

Holger Frauenrath, Jan Cornelius Brauer, Stephen Schrettl, Laurent Alexis Clément Vannay, Eric Albert Georges Bremond, Emmanuel Romaric Contal

The optoelectronic properties of various carbon allotropes and nanomaterials have been well established, while the purely sp-hybridized carbyne remains synthetically inaccessible. Its properties have therefore frequently been extrapolated from those of def ...

Improving visible light photocatalytic inactivation of E. coli by inducing highly efficient radical pathways through peroxymonosulfate activation using 3-D, surface-enhanced, reduced graphene oxide (rGO) aerogels

César Pulgarin, Stefanos Giannakis, Minoo Karbasi

In this work, we synthesized highly porous reduced graphene oxide foams, presenting augmented antibacterial activity in presence/absence of peroxymonosulfate (PMS). To date, this is the first investigation of photocatalytic PMS disinfection by 3D-rGO mater ...
