Article Abstract

We report a fully addressable smart textile display using quantum dot light-emitting diodes (QD-LEDs) featuring a highly durable electrode. The key innovation lies in the development of an ultrathin oxide/metal hybrid structure for the durable electrode, which achieves mechanical bending durability surpassing the indium tin oxide (ITO) electrode. The optimized electrode, composed of MoO and Au, exhibits a transmittance of = 81%, while maintaining a sheet resistance of = 17.92, achieving a Figure of Merit (FoM) of 0.0077. The bending tests further demonstrate that the QD-LEDs with this electrode retain their luminance up to 6325 cd m after undergoing 500 bending cycles at a bending radius of 5 mm. Furthermore, this study introduces not only a highly mechanically robust device, but also an integration method for textile systems by employing an innovative lateral driving display system architecture enabling the precise addressing of individual QD-LEDs in a textile display.

Ultra-sensitive pH-responsive drug delivery system designed to operate within the slightly acidic microenvironment of tumors are highly desired for hydrogel applications in cancer therapy. In this study, 4-Formylbenzoic acid modified polyvinyl alcohol (PVA-FBA, PF) was synthesized and utilized as a carrier for encapsulating the anticancer drug Doxorubicin (Dox). This was subsequently crosslinked with polyethylenimine (PEI) via benzoic-imine bond to form drug-loaded PVA-FBA/PEI hydrogel (D-PFP).

In this paper, lignin was chemically extracted from fibers and modified with branched polyethyleneimine (BPEI) and the resulting samples were applied for the adsorption of two anionic dyes; Acid red 183 (AR183) and Acid blue 25 (AB25) from aqueous suspension. Analytical characterization methods including SEM, FT-IR, TGA/DTG, and XRD were used to analyze the studied samples. The images of the extracted lignin displayed a rough feature.

The problem of hospital-acquired infections arising from inadequate antimicrobial and antibiofilm performance in medical textiles is an increasingly urgent threat to public health. The dual strategy combining superhydrophobic surfaces with aPDT exhibits potent antibacterial efficacy and barely triggers the risk of antimicrobial resistance, but still encounters significant challenges, including intricate fabrication methods and narrow spectral absorption of single-photosensitizer (PS) systems. A superhydrophobic-photodynamic dual antimicrobial polyester fabric is developed herein for medical applications to address these challenges.

Laccases, as multicopper oxidases, play a pivotal role in lignin degradation and hold broad industrial promise in biorefineries, bioremediation, textiles, and pulp and paper processing. However, their use is limited by poor stability under harsh operational conditions. Here, we designed a novel thermostable laccase (WCotA) from by combining data-driven mining with rational engineering.
