2D Vermiculite Nanolaminated Membranes for Efficient Organic Solvent Nanofiltration

open access: yesAdvanced Functional Materials, EarlyView.
Intercalating multivalent cations into 2D vermiculite nanolaminates significantly improves the structural stability and sieving capabilities of membranes in both aqueous and organic media, rendering them effective for organic solvent nanofiltration. Abstract Membrane separation technology has found widespread application in molecular sieving and water ...

A Novel Protein‐Polysaccharide Oral Nanoemulsion Targeting Activated Hepatic Stellate Cells to Enhance the Therapeutic Effect of Pirfenidone on Fibrosis After Transarterial Chemoembolization for Liver Cancer

open access: yesAdvanced Functional Materials, EarlyView.
Transarterial Chemoembolization (TACE) may aggravate liver fibrosis. In this study, a novel oral targeting nanoemulsion is fabricated to enhance the therapeutic effect of antifibrotic drug‐pirfenidone (PFD) on fibrosis after TACE. Studies have shown that PFD nanoemulsion can enhance the oral liver targeting effect of PFD, and effectively improve the ...

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

open access: yesAdvanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Recent Advances in Enzyme‐based Biofuel Cells Using Glucose Fuel: Achieving High Power Output and Enhanced Operational Stability

open access: yesAdvanced Functional Materials, EarlyView.
Effective electron transfer and stable enzyme immobilization, both between enzymes and host electrodes as well as between adjacent enzymes, are crucial for optimizing the biofuel cell (BFC) performance. Recently, efforts have focused on integrating these strategies with porous host electrodes.

Focal plane array detector-based micro-Fourier-transform infrared imaging for the analysis of microplastics in environmental samples

open access: yes, 2015
The pollution of the environment with microplastics (plastic pieces ,5 mm) is a problem of increasing concern. However, although this has been generally recognised by scientists and authorities, the analysis of microplastics is often done by visual ...

Magnetic Field‐Assisted Conductive Nerve Guidance Conduit Enabling Peripheral Nerve Regeneration with Wireless Electrical Stimulation

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a conductive nerve guidance conduit integrated with wireless electrical stimulation through alternating magnetic fields, which induces currents and creates a supportive microenvironment for nerve regeneration. In vivo studies show that this approach significantly enhanced myelin restoration, gastrocnemius muscle regeneration ...
