Construction of Phospholipid‐Like Vesicles by Aqueous Aminolysis of Acyl Thioesters With Diamino Acids

Chemistry – A European Journal, EarlyView.
Membrane‐forming phospholipids are produced in cells via enzymatic diacylation. Here, we show that direct aminolysis of acyl thioesters with diamino acids in aqueous environments enables the synthesis of diacylated amino acids (DAAAs), which spontaneously self‐assemble into robust phospholipid‐like vesicles across a broad range of pH and temperature ...

Poly(O‐Propargyl‐N‐Amino Carbamate), a Reactive Polymer to Underpin Biomedical Applications of Poly(acetylene)s

Macromolecular Rapid Communications, EarlyView.
We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...

Editorial - "Cultura Material, Arqueologia e Patrimônio"

Revista Memória em Rede, 2020
Memória apresenta duas facetas, a individual e a social, interlaçadas, mas diferentes. Em termos individuais (ἴδιος = dele), ou próprios (αὐτός = auto, próprio) a cada um, a lembrança é algo efêmero, seletivo, sujeito a contingências biológicas, além das psicológicas. As enfermidades podem alterar ou mesmo impedir as lembranças, a mostrar a sua base na

Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

People and Nature, EarlyView.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental
