Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability
Advanced Materials Technologies, EarlyView.ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...

Advanced Materials Technologies, EarlyView.We developed a flexible multi‐material printing strategy that employs sequential printing with different printers. This combined use of printers expands the accessible material scope. Moreover, incorporating Xolography as a sequential step enables support‐free, contactless printing, thereby enhancing structural design flexibility beyond conventional ...

Dynamic Current Routing in Conductive Liquid Crystal Elastomers for Complex Deformation Actuators
Advanced Materials Technologies, EarlyView.This work introduces a novel actuation control strategy in which electrical stimulation generates localized Joule heating in conductive liquid crystal elastomer (LCE) surfaces, enabling complex 3D deformations from a single homogeneous surface without preprogramming.

Advanced Materials Technologies, EarlyView.One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐

Rotaxanes via Michael Addition
Organic Letters, 2000[reaction: see text] The application of a template effect to the classical Michael addition of heteronucleophiles to various Michael acceptor systems leads in good yields to a new trapping synthesis of [2]rotaxanes with conjugated functional groups in their axles.

Michael additions of benzoins versus Michael-Stetter additions of aldehydes
Tetrahedron Letters, 1980Abstract Triethylamine catalyzed Michael additions of benzoins to chalcone can prevail over the expected Michael-Stetter additions when certain thiazolium ion conjugate bases - prepared in situ from the pertinent thiazolium salts and triethylamine- are used as catalysts.

Michael addition of artemisitene
Tetrahedron Letters, 2001Abstract Michael addition of artemisitene with triazole, benzotriazole or benzimidazole under non- or base-catalyzed conditions yielded compounds 3a – c and 4a – c . They showed high antimalarial activity against Plasmodium berghei in mice.
