Bio‐Based Epoxy Resins from Estragole: Achieving High Glass Transition Temperatures Comparable to DGEBA and Simultaneously Low Viscosities

open access: yesMacromolecular Materials and Engineering, EarlyView.
Two novel bio‐based epoxy monomers, diglycidyl‐4‐allylphenol (DG‐4A) and triglycidyl‐diallylphenol (TG‐DA), derived from estragole (92% and 72% bio‐content), were synthesized and cured with isophorone diamin (IPDA) and 4,4´‐diaminodiphenyl sulfone (DDS). The resins show high Tgs, with DG‐4A reaching and TG‐DA exceeding DGEBA‐based systems. These resins

Poly(2‐Oxazoline)‐Based Polyphotoacids: Synthesis, Solution Behavior, and Cellular Uptake of Multi‐Responsive Intracellular Transporters

open access: yesMacromolecular Rapid Communications, EarlyView.
The ability of photoacids to increase their acidity in response to light irradiation (excited state proton transfer, ESPT) makes them attractive building blocks for the design of stimuli‐responsive copolymers. In this contribution, we present highly biocompatible polyphotoacids based on poly(2‐oxazoline)s bearing 1‐hydroxypyrene units. Low cytotoxicity,

Fiber Reinforcement of Soft Spider Silk Hydrogels

open access: yesMacromolecular Rapid Communications, EarlyView.
Along the development of matrices for biomedical applications, precise tuning of the biomaterial to interact with specific cell types/tissues is essential. The fabrication of fiber mesh‐reinforced soft hydrogels made of recombinant spider silk proteins allows for the adjustment of mechanical properties and hydrogel porosity, leading to improved cell ...

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).
