Plato's concept of ἀνάμνησις in the Phaidon

Revista Filosófica de Coimbra, 2021
Dieser Aufsatz betrachtet einige zentrale Aspekte der Charakterisierung der ἀνάμνησις im Phaedo 72e‘ 77a. Er analysiert die innerlich hervorrufende Natur der ἀνάμνησις und die diese Hervorrufung beeinträchtigenden Faktoren von λήθη. Der Phaedo zeigt, 1.

Proper classes of maximal $θ$-independent families from large cardinals [PDF]

While maximal independent families can be constructed from ZFC via Zorn\u27s lemma, the presence of a maximal $σ$-independent family already gives an inner model with a measurable cardinal, and Kunen has shown that from a measurable cardinal one can ...

Radiative Thermal Management for Extreme Environments: Mechanisms and Design Strategies

Advanced Materials, EarlyView.
In this review, we discuss the fundamental mechanisms of radiative cooling and solar heating, material and structural design strategies, hybrid approaches integrating additional heat transfer pathways, and durability‐oriented designs addressing environmental stresses.

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 ...

Plasmon‐Enhanced Second‐Harmonic Generation in Atomically Thin Crystalline Silver Nanostructures

Advanced Materials, EarlyView.
Atomically thin crystalline silver films combine vertical quantum confinement with lateral plasmonic field enhancement to boost second‐harmonic generation. Nanoribbon and nanotriangle arrays enable geometry‐tunable infrared plasmon resonances, producing strong SHG from deeply subwavelength metallic volumes compatible with silicon‐based nanophotonics ...

Giant Anisotropic Spin Absorption in Chiral Hybrid Semiconductors

Advanced Materials, EarlyView.
Researchers uncover that chiral hybrid organic–inorganic semiconductors absorb spin differently depending on its polarization direction. This anisotropic spin absorption is primarily driven by the local symmetry breaking within the layered structure.

Efficient in‐Plane Exciton Transport in a Discontinuous Layered Lead‐Bromide Perovskite

Advanced Materials, EarlyView.
A new class of two‐dimensional lead‐bromide perovskite based on monovalent 4‐aminomethylbenzoic acid cations is presented, featuring a discontinuous inorganic layer. Despite the discontinuous lattice, transient photoluminescence microscopy demonstrates efficient though strongly anisotropic in‐plane exciton transport.

Effect of Surfactant on Bubble Formation on Superhydrophobic Surface in Quasi-Static Regime

Biomimetics
We experimentally studied the effect of a surfactant on bubble formation on a superhydrophobic surface (SHS). The bubble was created by injecting gas through an orifice on the SHS at a constant flow rate in the quasi-static regime.
