Distanzabhängiger Energietransfer zwischen organischen Fluorophoren und einwandigen Kohlenstoffnanoröhren

Angewandte Chemie, Volume 138, Issue 12, 16 March 2026.
Wir zeigen, dass hybridisierte dsDNA eine senkrechte Ausrichtung zu SWCNTs einnimmt, und präsentieren eine abstandsabhängige Übertragung der Energie von Fluoreszenzfarbstoffen auf SWCNTs. Der Energietransfer von Kohlenstoffnanoröhren (CNET) folgt einer d−5‐Abhängigkeit mit einem charakteristischen Abstand von 7,4 nm (± 0,7 nm) für 50 % Energietransfer.

Dynamischer Austausch von Bindemolekülen steigert die Effizienz der Proteinmarkierung in DNA‐PAINT um das bis zu 15‐Fache

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Der dynamische Austausch von Bindemolekülen (Dynamic Binder Exchange; DyBE) nutzt transiente Binde–Zielprotein‐Interaktionen, um die Markierungseffizienz in der superauflösenden Mikroskopie um das 15‐Fache zu steigern. DyBE kartiert die Organisation von Rezeptor‐Tyrosinkinasen (RTKs), einschließlich HER2‐Homodimere und EGFR–HER2‐Heterodimere, auf der ...

Memoria e imagen [PDF]

Educação & Realidade, 2012
Imagen y narración se unen de modo indisociable en todo intento - y por ende, en toda política - de transmisión de la memoria. Tanto por la dimensión icónica de la palabra, que hace del relato una pantalla proyectiva de nuestra imaginación - imaginación no menos verdadera que la que atestiguan las imágenes- como por el carácter narrativo de la imagen ...

Color as A Narrative Device in Illustration: A Systematic Review

Color Research &Application, Volume 51, Issue 2, March/April 2026.
Color in picture book illustration operates simultaneously as a representational code, cognitive scaffold, and affective cue supporting theories such as Dual Coding and multimodal discourse while revealing gaps in methodology and cross‐cultural research.

Imagens do despertar, imagens do rememorar

Revista Limiar, 2021
O presente artigo se propõe a fazer uma leitura da obra Em busca do tempo perdido, de Marcel Proust, em especial da primeira parte de No caminho de Swann, a partir de temas e questões que preocuparam o pensador e crítico Walter Benjamin, ele próprio leitor de tradutor de Proust. Essa nossa leitura se detém, assim, no tema proustiano (e benjaminiano) do

Mapping developmental transitions in mental health from mid‐ to late‐adolescence: Concurrent and longitudinal links to cognition

JCPP Advances, Volume 6, Issue 1, March 2026.
Abstract Background Developmental changes in mental health are mostly mapped between childhood and adolescence or childhood and adulthood. This study maps developmental transitions in mental health profiles from mid‐ to late‐adolescence, exploring how these transitions relate to cognitive function in mid‐adolescence. Method Participants from the IMAGEN
