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 ...

Porous Organic Cages as Building Blocks for Framework Materials

open access: yesAngewandte Chemie International Edition, Accepted Article.
Confined nanospaces play a fundamental role in nature, inspiring synthetic analogues that emulate biological precision and efficiency. Among these, porous crystalline materials such as covalent organic frameworks (COFs), metal‐organic frameworks (MOFs), and molecular cage compounds have emerged as powerful platforms for catalysis, separation, and ...

On‐Paper Enzyme‐Linked and Metal‐Linked Immunosorbent Assays for Low‐Cost Decentralized Testing of Carcinoembryonic Antigen

open access: yesAnalysis &Sensing, EarlyView.
On‐paper enzyme‐linked and metal‐linked immunosorbent assays (p‐ELISA and p‐MeLISA, respectively) were developed for the assay of carcinoembryonic antigen (CEA) in serum. These approaches are based on bio‐conjugated paper disks as analytical platform.

Ultrathin Self‐Assembled and Surface‐Attached Hydrogel Coating on Titanium for Potential Nanogluing of Implants

open access: yesJournal of Applied Polymer Science, EarlyView.
A self‐assembling and surface‐attached hydrogel coating was developed for titanium, combining phosphonate anchoring and phenyl azide crosslinking. The ultrathin, swellable films show long‐term stability, biocompatibility, and strong nanoparticle immobilization.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

open access: yesThe Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.
