Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

A Termite‐Inspired Alternative to Cement

open access: yesAdvanced Functional Materials, EarlyView.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

Robust Bio‐Textiles Via Mycelium‐Cellulose Interface Engineering

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a new class of sustainable textiles by growing mycelium, the root‐like structure of fungi, into cellulose‐based fabrics. This semi‐interpenetrating mycelium‐cellulose fiber network combines the strength and breathability of natural fibers with the water‐resistant and adhesive properties of mycelium, resulting in a robust, scalable,

Differences in the permeability assessment of the fractured reservoir rocks using the conventional and the rough discrete fracture network modeling

open access: yesJournal of Petroleum Exploration and Production Technology, 2023
Permeability assessment of naturally fractured rocks and fractured rocks after fracturing is critical to the development of oil and gas resources. In this paper, based on the discrete fracture network (DFN) modeling method, the conventional discrete ...
