Comparison of Mechanical Properties of Lignin/High‐Density Polyethylene (HDPE) Composites and Wood/HDPE Composites

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 5, February 5, 2026.
Manufacturing process and mechanical testing of lignin polymer composites. ABSTRACT Lignin is a plant‐derived, the second most abundant natural polymer, and a waste byproduct of the pulp industry. Incorporation of lignin into plastic composites using scalable approaches is commercially favored and low carbon‐cost.

Optimizing Soil Properties Through Hydrogel and Sawdust Combinations for Better Plant Growth

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 168-178, February 2026.
This graphical abstract illustrates the effects of various soil amendments on poplar cutting vitality under drought conditions, as observed using X‐ray computed tomography (CT). It compares soil alone, soil with sawdust, soil with hydrogel, and their combination, highlighting differences in internal structure, water retention, and root development.

XAFS analysis of Arsenic bound in holocellulose extracted from organic-rich contaminated sediments [PDF]

open access: yesE3S Web of Conferences, 2019
The arsenic bound in holocellulose, a precursor of humic substances extracted from organic contaminated sediments, was investigated using XANES (x-ray adsorption near-edge structure) and EXAFS (extended x-ray absorption fine structure) with fluorescence ...

Chemical characterization of imperata cylindrical (`Lalang`) and pennisetum purpureum (Napier grass) for bioethanol production in Malaysia [PDF]

open access: yes, 2013
Grass is a candidate biomass producer because it is fibrous and it thrives well on poor soils. The chemical properties of two grass species growing naturally and abundantly on idle lands in Malaysia were investigated in this study.

Compression wood in Pinus radiata II: Density and chemical composition

open access: yesMaderas: Ciencia y Tecnología, 2014
Ten 22 year old radiata pine trees growing in two stands in Chile, one in clay and the other in humid sand soils showing some lean, were assessed for chemical composition and wood density of compres-sion wood. Signifi cant differences in type of wood in

Challenges in lignin valorization during biomass hydrogenolysis for ethylene glycol production

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 268-279, January/February 2026.
Abstract This study examined the extent to which lignin upgrading is possible when maximizing ethylene glycol (EG) production during the hydrogenolysis of lignocellulosic biomass over bifunctional tungsten–nickel catalysts. Reductive catalytic fractionation (RCF) was selected as a benchmark lignin valorization process because its reaction conditions ...
