Flow Analysis in Pathological Microvascular Models by Ultrasound Localization Microscopy

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a new platform combining ultrasound localization microscopy with biomimetic gelatin phantoms to analyze flow dynamics in small vessels with narrowing or obstructions. Using microbubble tracking, the method enables high‐resolution velocity mapping in 100–500 µm channels, revealing flow changes in pathological microvascular conditions

Adaptive Elastin‐Like Hydrogel with Unidirectional and Controllable Anisotropic Actuation for Soft Robotics and Tissue Engineering

open access: yesAdvanced Materials Technologies, EarlyView.
Fiber‐reinforced elastin‐like tubular scaffolds are engineered to achieve anisotropic and reversible actuation under external stimuli. By adjusting fiber's angle, actuation behavior is finely tuned, enabling distinct actuation responses, even within different regions of the same scaffold.

Improving the Photochemical Skeletal Enlargement of Pyridines to 1,2‐Diazepines with Isocyanates

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract In this work, we extend the one‐pot protocol to synthesize 1,2‐diazepines from commercially available and cheap starting materials. Capitalizing on isocyanate derivatives as activating agents, the photochemical skeletal enlargement occurs, while preserving key functional groups embedded in more than 30 substrates.

Chemoselective Synthesis of α‐Chloro and α,α‐Dichloro Acetamidines via the Carbenoids Addition to Inherently Low Electrophilic Carbodiimides

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Carbodiimides act as competent electrophilic synthons for the chemoselective addition of lithium mono‐ and di‐halocarbenoids. The transformation is provided through a single synthetic operation—hitherto elusive—halogenated acetamidines. Interestingly, the constitutively tamed electrophilicity of the starting materials is effectively counterbalanced by ...

Electrochemical Chemo‐ and Regioselective Heterofunctionalization of Tropones via C(sp2)H Derivatization

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Simple and selective. The electrochemical heterofunctionalization of activated tropones is achieved using readily available inorganic salts. A theoretical model, based on cyclic voltammetry and quantum chemistry calculations, predicts both reactivity trends and site selectivity.
