Metal‐Organic Nanosheet Gels: Hierarchically Porous Materials for Selective Loading and Differential Release

open access: yesAdvanced Functional Materials, EarlyView.
A suspension of metal‐organic nanosheets was centrifuged to form self‐healing gels with a hierarchically porous structure. The prepared gels were used to selectively capture small molecules from solutions and differentially release them based on their size and charge. Abstract Metal‐organic nanosheets (MONs) are intrinsically porous 2D materials with a

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

open access: yesAdvanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Purification and Partial Characterization of Trypanosoma cruzi Triosephosphate Isomerase

open access: yesMemorias do Instituto Oswaldo Cruz, 1998
The enzyme triosephosphate isomerase (TPI, EC 5.3.1.1) was purified from extracts of epimastigote forms of Trypanosoma cruzi. The purification steps included: hydrophobic interaction chromatography on phenyl-Sepharose, CM-Sepharose, and high performance ...

Tunable Synthetic Hydrogel Modulates Hepatic Lineage Specification of Human Liver Organoid

open access: yesAdvanced Functional Materials, EarlyView.
In this study, a synthetic hydrogel is reported that supports the formation of hiPSC‐derived human liver organoids (HLOs). Hepatic lineage specification can be modulated via conjugation of RGD peptide to hydrogel: RGD‐conjugated hydrogels promote cholangiocyte differentiation, whereas RGD‐free hydrogels favor hepatocyte commitment of HLO cells.

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

open access: yesAdvanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Exploiting the Functionality of Cerium Oxide‐Modified Carbon Nanohorns Catalysts Toward Enhanced CO2 Reduction Performance

open access: yesAdvanced Functional Materials, EarlyView.
A cerium oxide‐carbon nanohybrid catalyst is synthesized via two distinct routes and is integrated into H‐type cells and gas diffusion layers (GDLs) to enhance electrochemical performance. Structural variations significantly affect performance, with the solvothermal sample exhibiting higher current densities.

Molecular Engineering of Coacervate Network Binders for Stable Silicon‐Based Anodes in Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A coacervate charged polymer network is designed to regulate Coulomb interactions for stabilizing silicon anodes. By tuning electrostatic interactions, the binders enhance adhesion, stress dissipation, and interfacial stability. The binder with the strongest Coulomb interactions enables high areal capacities and stable full‐cell cycling with Ni‐rich ...
