Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

On the Relation between the Inclination Angle of the Accretion Disk and the Broad-line Region in Active Galactic Nuclei

The Astrophysical Journal
Models of active galactic nuclei (AGN) often invoke a close physical association between the broad-line region (BLR) and the accretion disk. We evaluate this theoretical expectation by investigating the relationship between the inclination angle of the ...

Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

Advanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

On ἐλευθερία, τὸ ζῆν ὡς βούλεταί τις, and Virtue in the Aristotelian Theory of Demokratia

Revista Archai
In this paper, I aim to reject the thesis that ancient democracy, according to Aristotle, is defined by majority rule for its own benefit. I advocate for an alternative thesis, (which easily incorporates what is true in the rejected view), namely, that it is the concept of eleutheria, particularly as understood in Politics VI.2 and VI.9, that holds ...

Who breathes and smells according to Empedocles? On the πάντα of fr. 96. 1 Gallavotti

Revista Archai, 2018
Aristotele (Resp. 473a-474a), Teofrasto (Sens. 9 e 20-22) e Demetrio Lacone (PHerc. 1012, col. 65) hanno conservato l’ampio resoconto in versi del meccanismo della respirazione e dell’olfatto di Empedocle. Tale spiegazione non dichiara però esplicitamente quanti viventi possiedono una simile facoltà .

Measurement of the differential γ+2b -jet cross section and the ratio σ(γ+2b-jets)/σ(γ+b-jet) in pp¯ collisions at s=1.96 TeV

Physics Letters B, 2014
We present the first measurements of the differential cross section dσ/dpTγ for the production of an isolated photon in association with at least two b -quark jets. The measurements consider photons with rapidities |yγ|<1.0 and transverse momenta 30<pTγ<200 GeV .

Weak In‐Plane Ferromagnetism and Electronic Nematicity in the Distorted Triple‐Q Magnetic Phase of Co1/3TaS2

Advanced Materials, EarlyView.
Co1/3TaS2${\rm Co}_{1/3}{\rm TaS}_{2}$ hosts a triple‐Q noncoplanar antiferromagnetic state with coexisting Z3${\rm Z}_3$ electronic nematicity. We report rotational hysteresis observed in both magnetoresistance and magnetic torque, revealing strongly pinned in‐plane weak ferromagnetic moments in the triple‐Q phase and the magnetism‐driven nature of ...

Programming of Complex Magnetic Profiles Enforced by 4D Printed Magnetic LCE Actuators

Advanced Materials, EarlyView.
A 4D printing‐enabled magnetic programming strategy is introduced in which thermally actuated liquid crystal elastomers are magnetized in their target shape to encode complex three‐dimensional magnetic profiles. The resulting actuators achieve multistate shape morphing and programmable locomotion under low magnetic fields, without requiring specialized

Giant Orbital Rashba–Edelstein Effect in Crystalline Cu2O/Cu Heterostructures

Advanced Materials, EarlyView.
An enhanced orbital Rashba–Edelstein effect is demonstrated in a crystalline Cu2O/Cu heterostructure, compared to naturally oxidized CuOx structures, highlighting the critical role of crystallinity and interface control in orbital torque generation. The resulting spin torque conductivity exceeds that of Pt, indicating the potential of orbital torque ...
