Amphoteric surfactants containing ?-hydroxy ester group and an amino acid residue

open access: yesGrasas y Aceites, 2006
A series of amphoteric surfactants containing α-hydroxy ester group and an amino acid residue were prepared with the addition of epoxy derivatives (which were prepared from epoxidation of alkyl methacrylate) to different types of amino acids (glycine ...

Tailoring the Properties of Functional Materials With N‐Oxides

open access: yesAdvanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Tunable and Recyclable Piezoelectric Biomaterials via Ion‐Directed Guanine‐Quadruplex Assembly

open access: yesAdvanced Functional Materials, EarlyView.
Guanine‐quadruplex (GQ) assemblies, formed via ion‐mediated self‐assembly of amphiphilic guanine derivatives, are introduced as tunable and recyclable piezoelectric biomaterials. Distinct alkali ions induce unique dipole configurations and piezoelectric outputs, with K⁺ yielding the highest performance.

Robust Bio‐Textiles Via Mycelium‐Cellulose Interface Engineering

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a new class of sustainable textiles by growing mycelium, the root‐like structure of fungi, into cellulose‐based fabrics. This semi‐interpenetrating mycelium‐cellulose fiber network combines the strength and breathability of natural fibers with the water‐resistant and adhesive properties of mycelium, resulting in a robust, scalable,
