3D‐Printed and Recombinant Spider Silk Particle Reinforced Collagen Composite Scaffolds for Soft Tissue Engineering

open access: yesAdvanced Functional Materials, Volume 35, Issue 15, April 10, 2025.
The newly developed, combined 3D‐extrusion bioprinting process of a collagen ink and a recombinant spider silk precipitation bath with a subsequent potassium phosphate post‐treatment fabricates spider silk particle‐reinforced, fibrillar collagen scaffolds with promising properties for soft tissue engineering.

De quelques catéchismes créoles anciens: oublis, pertes, disparitions, réapparitions, découvertes [PDF]

open access: yes, 2015
Il existe, dans le très vaste domaine des études postcoloniales, des territoires contigus ou semblables qui connaissent des phénomènes communs mais aux histoires très différentes, sinon radicalement opposées : tels les catéchismes - en langues romanes ...

Joule‐Assisted Nanotherapeutic Urethral Stent (JANUS) for Spatiotemporal Theragenerative Treatment of Urethral Strictures

open access: yesAdvanced Functional Materials, EarlyView.
Joule‐assisted nanotherapeutic urethral stent harnesses a smart, biodegradable magnesium stent to orchestrate spatiotemporal theragenerative therapy for urethral strictures. Magnetically induced Joule heating enables on‐demand drug release and bacterial ablation, while simultaneously guiding urothelial regeneration.

The Golden City on the Edge: Economic Geography and Jihad over Centuries [PDF]

open access: yesarXiv, 2022
This paper uncovers the evolution of cities and Islamist insurgencies, so called jihad, in the process of the reversal of fortune over the centuries. In West Africa, water access in ancient periods predicts the locations of the core cities of inland trade routes -- the trans-Saharan caravan routes -- founded up to the 1800s, when historical Islamic ...

Ultra‐Effective Light‐Activated Antibacterial Activity via Carboxyl Functionalized Graphene Quantum Dots and Films

open access: yesAdvanced Functional Materials, EarlyView.
Carboxyl‐functionalized graphene quantum dots (cGQDs) exhibit high singlet oxygen quantum yield due to strong spin–orbit coupling. cGQDs achieve minimum bactericidal concentration of only 0.4 µg mL−1 against S. aureus under low‐intensity illumination.

Mesoscopic colonization of a spectral band [PDF]

open access: yes, 2009
We consider the unitary matrix model in the limit where the size of the matrices become infinite and in the critical situation when a new spectral band is about to emerge. In previous works the number of expected eigenvalues in a neighborhood of the band was fixed and finite, a situation that was termed "birth of a cut" or "first colonization".

The Cosmic Hitchhikers Hypothesis: Extraterrestrial Civilizations Using Free-Floating Planets for Interstellar Colonization [PDF]

open access: yesarXiv, 2022
I propose the Cosmic Hitchhikers hypothesis as follows. Advanced extraterrestrial civilizations may use free-floating planets as interstellar transportation for space exploration and interstellar colonization. Large groups or populations of their biological species, post-biological species, and technologies may become Cosmic Hitchhikers when they ride ...
