High Thermoelectric Performance in Low‐Cost Cu8SiSxSe6‐x Argyrodite

open access: yesAdvanced Functional Materials, EarlyView.
This study discovers the great potential of Cu8SiSxSe6‐x argyrodites as new, low‐cost, Te‐free thermoelectric materials. The proposed defect scheme suppresses the phase transition, enhances the weighted mobility and optimizes the grain boundary contacts.

Valorisation of lignin – Achievements of the LignoValue project [PDF]

open access: yes
Lignocellulosic biorefinery for production of biofuels, materials and chemicals requires valorization of all fractions including lignin. As a consequence of its poly-aromatic structure, lignin potentially serves as a source for aromatic chemicals.

Investigating the Structure–Function Relationships of Fluorinated Interfaces for PFAS Capture and Electrochemically‐Mediated Release

open access: yesAdvanced Functional Materials, EarlyView.
This study explores the use of fluorinated copolymers with varying fluorophilic side chain lengths to enhance PFAS affinity. The integration of electrochemical techniques demonstrates enhanced adsorbent regeneration, with molecular dynamics simulations providing insight into the molecular‐level interactions involved.

Handling sticky resin by stingless bees (Hymenoptera, Apidae)

open access: yesRevista Brasileira de Entomologia, 2011
For their nest defense, stingless bees (Meliponini) collect plant resins which they stick on intruders like ants or cleptobiotic robber bees causing their immobilization.

Coupling Interfacial Redox‐Reactions with In Situ Proton Generation for the Photoelectrochemical Separation of Rare‐Earth Elements

open access: yesAdvanced Functional Materials, EarlyView.
To enhance the sustainability of electrochemical separations for resource recovery, a photoelectrochemical ion recovery system is developed that utilizes renewable solar energy. A composite integrating titianium dioxide nanorods and a redox‐copolymer enables spontaneous cation adsorption and light‐activated redox reactions for regeneration, thus ...
