Einfluss des Ligandendesigns und nicht‐kovalenter Wechselwirkungen auf die isotaktische Ringöffnungspolymerisation von rac‐β‐Butyrolacton unter Verwendung von Salan‐ und Salalen‐Seltenen Erden Metallkatalysatoren

open access: yesAngewandte Chemie, EarlyView.
Polyhydroxybutyrate sind wichtige Vertreter von nachhaltigen Polyestern, bei denen jedoch die Kontrolle der Stereoregularität entscheidend ist, um vielversprechende thermische und mechanische Eigenschaften zu erzielen. Hochaktive Seltenerdmetall‐Salan/Salalen‐Komplexe erzielen isotaktisches (Pm bis zu 0.96 bei 0 °C) oder syndiotaktisches (Pr bis zu 0 ...

DE UMA FENOMENOLOGIA DO DESIGN: UMA INVESTIGAÇÃO SOBRE O FUNDAMENTO DAS RELAÇÕES DE USO FACE AO PROPÓSITO DE MANUTENÇÃO DA VIDA

open access: yesMix Sustentável, 2023
O Objetivo principal do estágio de pós-doutoramento consistiu em explorar conceitos filosóficos, das obras de Martin Heidegger, Hannah Arendt e Hans Jonas, que pudessem fundamentar as relações de uso, com vista ao design, e com o propósito da manutenção

Well-Posedness and Regularity of the Heat Equation with Robin Boundary Conditions in the Two-Dimensional Wedge [PDF]

open access: yesarXiv
Well-posedness and higher regularity of the heat equation with Robin boundary conditions in an unbounded two-dimensional wedge is established in an $L^{2}$-setting of monomially weighted spaces. A mathematical framework is developed which allows to obtain arbitrarily high regularity without a smallness assumption on the opening angle of the wedge.

Coordinative Ring‐Opening Polymerization of Limonene Carbamate towards Phosgene‐ and Isocyanate‐Free Polyurethane

open access: yesAngewandte Chemie International Edition, Accepted Article.
This study presents a phosgene‐ and isocyanate‐free route for the synthesis of polyurethanes using (R)‐limonene as a bio‐based starting material. The synthesis of the cyclic limonene‐based carbamate monomer LU is achieved in high yields using dimethyl carbonate as a sustainable, less hazardous phosgene surrogate and is verified by NMR, SC‐XRD, ESI‐MS ...

The Clever Hans Effect in Unsupervised Learning [PDF]

open access: yes
Unsupervised learning has become an essential building block of AI systems. The representations it produces, e.g. in foundation models, are critical to a wide variety of downstream applications. It is therefore important to carefully examine unsupervised models to ensure not only that they produce accurate predictions, but also that these predictions ...

Hans Jonas And His Critics

open access: yesAufklärung, 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.
