Skin-Conformal Hydrogel-Based Electroencephalography Electrodes with Surfactant-Reorganized PEDOT:PSS

Published on 2025-10-19 by Ji-Yoon Ahn, Jihyeon Oh, Mi-Ri An, Kun-Woo Nam, Jin-Whan Kim, Sung-Hoon Park @MDPI

Abstract: Electroencephalography (EEG) electrodes require low impedance, high biocompatibility, and long-term performance. Conventional Ag/AgCl wet electrodes achieve low impedance but suffer from dehydration and skin irritation, whereas dry electrodes often induce discomfort or exhibit high impedance. To address these limitations, this study engineered a hydrogel-based electrode by incorporating PEDOT:PSS and the nonionic surfactant Triton X-100 into an acrylic acid hydrogel matrix. The flexible acrylic [...]


Our summary: This study presents a hydrogel-based EEG electrode incorporating PEDOT:PSS and Triton X-100. The electrode demonstrates low impedance, high biocompatibility, and mechanical compliance. It shows comparable performance to traditional Ag/AgCl electrodes in EEG measurements.

Co-Degradation of Coal and Sawdust for Enhanced Microbial Methane Production

Published on 2025-10-17 by Liu Zhu, Wangjie Diao, Zeguang Tang, Yi Liu, Yanxin Gu @MDPI

Abstract: Microbial coal gasification is a highly promising bioenergy technology, yet its efficiency is often constrained by the highly polymeric structure of coal. This study explores a novel approach to enhance methane production from low-rank coal through anaerobic co-degradation with sawdust. Using Xilinguole lignite as the substrate, we systematically assessed how wood chip supplementation influences microbial degradation efficiency and community dynamics. Results demonstrated that co-degradation sig[...]


Our summary: This study investigates the co-degradation of low-rank coal with sawdust to enhance methane production. Results show that a coal-to-wood chip ratio of 4:1 significantly increases methane yield compared to coal alone. The addition of sawdust improves microbial community dynamics and promotes efficient degradation of complex compounds.

Effects of 3D Printing Parameters on the Coating Performance of Chinese Lacquer on PLA Substrates

Published on 2025-10-17 by Yi Xie, Yuemin Feng, Alin Olarescu, Yushu Chen, Xinyou Liu @MDPI

Abstract: This study systematically investigates the influence of 3D printing parameters on the surface morphology and coating performance of polylactic acid (PLA) substrates finished with traditional Chinese lacquer. PLA specimens were fabricated using fused deposition modeling (FDM) with varying print speeds, layer heights, and infill densities, followed by natural lacquer coating and controlled curing. Surface roughness, gloss, adhesion, and wear resistance were evaluated through standardized tests, wh[...]


Our summary: This study examines how 3D printing parameters affect the coating performance of PLA substrates with Chinese lacquer. Layer height significantly influences surface roughness, gloss, adhesion, and wear resistance. The findings suggest that integrating traditional lacquer with FDM technology enhances the quality of 3D-printed finishes.

Silk coating of musical instruments and musical instrument components and accessories

Patent published on the 2025-10-16 in WO under Ref WO2025217387 by TRUSTEES OF TUFTS COLLEGE [US] (Omenetto Fiorenzo [us])

Abstract: The disclosure herein concerns stringed instruments, string picking implements, bows, silk-coated bows, and related methods. Musical instrument component properties can be influenced by a number of factors that result in the alteration of the component's behavior (e.g., vibrational) which determines its playing characteristics and tone richness. One such factor is its coating or impregnation with silk fibroin.[...]


Our summary: This content discusses the application of silk coating on musical instruments and their components. It highlights how silk fibroin can influence the vibrational properties and playing characteristics of stringed instruments. The methods and effects of silk-coated bows and accessories are also addressed.

Emerging Microbial and Enzymatic Approaches for Sustainable Antibiotic Biodegradation in Livestock Manure to Mitigate Water Pollution Risks

Published on 2025-10-14 by Zimin Gao, Jian Tan, Mohd Faheem Khan, Gaurav Chugh, Olaf Schmidt, Lu Ma, Dengpan Bu @MDPI

Abstract: The extensive use of antibiotics in animal husbandry leads to the release of unmetabolised residues and the dissemination of antimicrobial resistance genes (ARGs) in manure, posing environmental and public health challenges. Conventional treatment technologies, including hydrolysis, photodegradation, and phytoremediation, are often constrained by incomplete mineralisation, high cost, and environmental variability. Biocatalytic and microbially mediated processes are increasingly recognised as sus[...]


Our summary: This review discusses sustainable microbial and enzymatic strategies for antibiotic biodegradation in livestock manure. It highlights the challenges posed by conventional treatment methods and the potential of biocatalytic processes to mitigate water pollution risks. Advances in enzyme engineering and microbial consortia are emphasized as promising solutions for effective manure management.

Published on 2025-10-11 by Shuyan Duan, Zhaoyi Wei, Yushan Wei, Xiaoyue Cai, Yixuan Liu, Ruiran Fan @MDPI

Abstract: The continuous increase in demand for polyethylene terephthalate (PET) has drawn global attention to the significant environmental pollution caused by the degradation of PET plastics. Exploring new PET-degrading enzymes is essential for enhancing the degradation efficiency of PET, and esterases and lipases with plastic degradation capabilities have become a focal point of research. In this study, we utilized the ultra-efficient mutant FASTase of the PET-degrading enzyme IsPETase, derived from Id[...]


Our summary: The study investigates the hydrolytic activity of esterase Gs from Geobacillus sp. JM6 on PET model substrates. Gs shows excellent degradation of bis(2-hydroxyethyl) terephthalate (BHET) but lacks thermal stability. The combination of Gs and MHETase can completely hydrolyze BHET, offering new resources for PET plastic degradation.
