Advanced Materials, EarlyView.To address functionality limitations in plant‐based and industrially compostable polymer aerogels, this work introduces bio‐inspired aerogels with broadened functionality. Inspired by functional plant tissues, lightweight biopolymer aerogels based on exclusively stereocomplex crystals are fabricated, featuring hierarchically macro‐/meso‐porous ...

, 2010 In addition to his prolific and fecund scientific activity, Paolo Farinella devoted a considerable amount of his time and energies to the political, military and social implications of space activities and research. Most of these interests may be collectively included under the expression "security in space".

Advanced Materials, EarlyView.Melt electrofibrillation (MEF) enables the fabrication of nanofibrillar PCL scaffolds with defined architectures that guide cellular alignment and retention during cartilage tissue engineering. Unlike conventional melt electrowriting, MEF consistently directs collagen type II‐rich extracellular matrix organization, providing a tunable platform to ...

Advanced Materials, EarlyView.Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

Η ανθρώπινη παρουσία στο διάστημα παρουσιάζει τόσο συναρπαστικές ευκαιρίες όσο και σημαντικές προκλήσεις ασφαλείας. Αυτή η διατριβή εξετάζει το εξελισσόμενο τοπίο ασφαλείας που περιβάλλει τις διαστημικές δραστηριότητες. Αναλύει τους κινδύνους που συνδέονται με τον αυξανόμενο αριθμό δορυφόρων σε τροχιά γύρω από τη Γη, συμπεριλαμβανομένων πιθανών ...

Interface‐Mediated Catalysis for Improved Hydrogen Storage in Reactive Hydride Composites
Advanced Materials, EarlyView.Catalyst–hydride interfaces are engineered in Co@C‐ and Ni@C‐modified 2LiH + MgB2 reactive hydride composites to accelerate hydrogen uptake and release. Multiscale scattering, in‐situ synchrotron radiation powder x‐ray diffraction and density functional theory calculations reveal the structural and electronic origin of the catalytic enhancement ...

Bridging Biosensing and Hardware‐Level Data Security With a Conjugated Radical Polymer
Advanced Materials, EarlyView.A conjugated radical polymer provides two complementary functions within a common material platform: sensitive dopamine biosensing and device‐specific stochastic electrical responses for security. The work demonstrates a materials‐based approach for combining bioelectronic signal acquisition with hardware‐level authentication while maintaining the ...
