Long‐Range Spin Transport in Chiral Gold

open access: yesAdvanced Materials, EarlyView.
It is demonstrated that in chiral gold film, spin information can be transferred to distances of several microns at room temperature. The conduction of spins is accompanied by the Hall effect that exists without applying an external magnetic field. The spin diffusion length is consistent with the frequency‐dependent Hall effect which indicates spin ...

Hans Jonas e seus críticos

open access: yesAufklärung: journal of philosophy, 2014
O presente artigo apresenta duas críticas mais elaboradas ao projeto jonasiano, a saber: aquela feita a partir da pragmática transcendental de K.O-Apel e a feita a partir do pensamento de Paul Ricouer. Os dois filósofos se confrontam com o princípio responsabilidade de Jonas, indicando suas lacunas e limites.

Antifouling Surface‐Attached Hydrogel Nanocoatings Redefined: Green Solvent‐Based, Degradable, and High‐Performance Protection Against Foulants

open access: yesAdvanced Materials Interfaces, EarlyView.
An ultrathin surface‐attached hydrogel coating is introduced that, unlike the best antifouling coatings so far, consists of hydrophilic, non‐charged, green solvent‐based monomers. It effectively renders the surfaces of medical devices stealth toward proteins, a clinical strain of MRSA and blood while offering on‐demand degradability to regenerate the ...

Mitigating Molecular Aggregation in Drug Discovery With Predictive Insights From Explainable AI

open access: yesAngewandte Chemie, EarlyView.
In this work, MEGAN, our explainable AI model, is applied to predict small colloidally aggregating molecules (SCAMs), a significant source of false positives in drug discovery. MEGAN provides interpretable predictions and proposes structurally similar, non‐aggregating alternative molecules.

The Impact of Donor‐Orientation on the Emission Properties of Chlorinated Trityl Radicals

open access: yesAdvanced Optical Materials, EarlyView.
Chlorinated trityl radicals with electron‐donating groups enable efficient red emission for optoelectronics. Donor orientation and steric constraints regulate vibronic coupling, influencing luminescence. A novel trityl derivative with restricted donor alignment minimizes non‐radiative decay, enhancing quantum yield.

Thiotemplated Polyketide Chain Fusion and Reductive Cyclization Build the Reactive Butenolide Core of Malleicyprol

open access: yesAngewandte Chemie, EarlyView.
Malleicyprol, a virulence factor of notorious animal and human pathogens of the Burkholderia pseudomallei (BP) group, results from the fusion of two individual polyketide chains. The noncanonical condensation domain of the PKS–NRPS hybrid synthetase BurF forms an ester bond, and the terminal reductase domain mediates a reductive chain release followed ...

A educação contra a barbárie: um confronto entre os ideais adornianos e jonasianos

open access: yesHorizontes, 2013
Este trabalho tem por objetivo verificar o impulso destrutivo da humanidade, o porquê dessa nociva presença ao longo da história, como isso põe em perigo a permanência da vida na Terra e se é possível que se elimine tal impulso do indivíduo humano.

Fabrication Optimization of van der Waals Metasurfaces: Inverse Patterning Boosts Resonance Quality Factor

open access: yesAdvanced Optical Materials, EarlyView.
An optimized fabrication approach for the nanostructuring of optical metasurfaces from van der Waals materials like hexagonal boron nitride is presented. The resonator geometries show enhanced geometric homogeneity, resulting in a significant increase in quality factors of symmetry‐protected bound states in the continuum resonances.
