Data integration advances reproductive phenology research across temporal, spatial and taxonomic scales

open access: yesEcography, EarlyView.
Climate change is altering plant reproductive phenology; however, a scarcity of long‐term, systematic monitoring hinders our ability to quantify and predict these responses in many parts of the world. We addressed this gap by demonstrating how data integration can be used to produce a synthesised record of reproductive phenology observations (flowering

Biomass‐Derived Transparent Bamboo Composite Films with Europium‐Based Photoconversion for Energy‐Efficient Smart Agriculture

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A biomass‐based transparent bamboo composite doped with europium efficiently converts UV light into photosynthetically active red light, significantly enhancing plant growth and providing a sustainable alternative to petroleum‐based agricultural films. The rational design of sustainable light‐conversion agricultural materials is critical for enhancing ...

Dual‐Functional Sulfonated Nanocellulose for Proton Exchange Membranes With High Proton Conductivity at Low Humidity

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable dual‐functional strategy yields simultaneously sulfonated and nanosized cellulose for proton exchange membranes with continuous hydrogen‐bond networks. These sustainable membranes exhibit low‐humidity proton conductivity twofold higher than Nafion 212, providing a robust solution for next‐generation fuel cells.

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

A review of the configuration of bordered pits to stimulate the fluid flow

open access: yesMaderas: Ciencia y Tecnología, 2014
As the bordered pits have generally been thought to have an influence on the refractory nature of softwoods, structural behaviour of this conducting pathways is discussed according to the published literature.

Flexural anisotropy of rift-sawn softwood boards induced by the end-grain orientation

open access: yesJournal of Wood Science, 2021
Inspired by the use of rift-sawn softwood board for covering curved surfaces in Kokerabuki, a traditional Japanese roofing method, we investigated the flexural anisotropy of wood caused by its end-grain orientation.

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

open access: yesFire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Prediction of Withdrawal Resistance of Self-Tapping Screws in Softwood Structural Lumber

open access: yesBioResources
The withdrawal resistance of self-tapping screws (STS) in Korean structural softwood in the vertical fiber direction was examined. Four representative softwood species were selected based on their specific gravity.
