Highly efficient single-step pretreatment to remove lignin and hemicellulose from softwood

open access: yesBioResources, 2019
The use of lignocellulosic softwood residues as feedstock for the production of bioethanol and other value-added chemical products has been limited by its high recalcitrance.

Current Knowledge on Phytoremediation Potential of Industrial Hemp (Cannabis sativa L.) for PFAS and Heavy Metal Contaminated Soils

open access: yesRemediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT This review synthesizes current research on the phytoremediation potential of industrial hemp (Cannabis sativa L.) for heavy metals, including arsenic, aluminium, mercury, copper, lead, cadmium, nickel, and zinc, as well as per‐ and polyfluoroalkyl substances (PFAS), commonly referred to as “forever chemicals.” A structured and transparent ...

Soil biological health and yield outcomes from integrating conservation agricultural practices in a corn–soybean system are dependent on environment

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Research examining the integration of conservation agricultural practices and their medium‐term effects on crop productivity and soil health remain limited within the corn (Zea mays L.)—soybean [Glycine max (L.) Merr.] system of northern US.

Centrifugal fractionation of softwood extracts improves the biorefinery workflow and yields functional emulsifiers

open access: yesGreen Chemistry, 2019
Centrifuging softwood extracts separated the hemicellulose-rich fraction and lignin-rich micro- and nanoparticles. The hemicellulose-rich fraction and lignin-rich nanoparticles formed stable emulsions.

Multilevel Impacts of Habitat Fragmentation on Plant Diversity and Structure in Urban Remnant Forests

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study of 30 urban remnant forest patches in Guiyang, China, found that edge habitats displayed greater forest structural metrics but reduced plant diversity linked to the clumpiness of surrounding impervious surfaces, whereas interior diversity suffered from high edge contrast and impervious clumpiness.

Photocatalytic Lignin Depolymerization and Cross‐Coupling With Alcohols to Produce Unsymmetric Aromatic Diols

open access: yesAngewandte Chemie, Volume 138, Issue 32, 3 August 2026.
A photocatalytic approach for efficient one‐pot direct lignin depolymerization and subsequent cross‐coupling with alcohols for the production of unsymmetrical aromatic diols has been demonstrated. ABSTRACT Conversion of lignin into chemical products typically involves two separate steps, such as depolymerization and subsequent upgrading of monomers ...

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

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
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.
