Selenophene π‐Bridge Enables Balanced Ambipolar Transport in High‐Performance Organic Electrochemical Transistors

open access: yesAdvanced Science, EarlyView.
We synthesized a high‐performance balanced ambipolar OECT polymer, P(gTDPPSe), via selenophene π‐bridge engineering. The selenophene π‐bridge enhances backbone planarity and optimizes the energy levels for doping, enabling high and balanced p/n‐type transconductance‐a key factor for high‐gain complementary inverters.

Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives

open access: yesAdvanced Electronic Materials, EarlyView.
The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.

Accelerated extraction of the fat content in cheese using a focused microwave-assisted soxhlet device

open access: yes, 2022
A fast method for hydrolysis and extraction of fat in cheese based on the use of a Soxhlet extractor assisted by microwaves is proposed. The use of this type of energy dramatically reduces the time required for both steps (namely, the hydrolysis time was

Donor–Acceptor Covalent Organic Framework Enables Ambipolar Charge Storage in Aluminum‐Ion Energy Storage

open access: yesAdvanced Energy Materials, EarlyView.
A donor–acceptor covalent organic framework is designed as an ambipolar cathode for aluminum‐ion energy storage. The crystalline, microporous architecture enables intrinsic charge transport without conductive additives. Multi‐electron redox activity at donor and acceptor sites supports high capacity, excellent stability, and efficient reversible ...

Separation of Polyamide 66 From Blends With Wool Through Selective Dissolution: Implications of the Presence of Dyes

open access: yesJournal of Applied Polymer Science, EarlyView.
The study assesses dye impacts on PA66/wool recycling via selective PA66 dissolution in calcium chloride–ethanol–water and water reprecipitation. Acid dyes migrate into solvent, yielding color‐free, melt‐spinnable PA66 and reusable wool. Metal‐complex dyes remain, altering PA66 melt viscosity and requiring extraction or repurposing.
