Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

Carbon Energy, EarlyView.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Valorization of Poplar Wood Wastes Into 3D‐Printed Soya Oil‐Based Composites by Vat Photopolymerization for Interior Design

Journal of Polymer Science, EarlyView.
Bio‐based polymer composites were 3D printed by LCD vat photopolymerization using acrylate epoxidized soybean oil as the monomer and isobornyl methacrylate as the reactive diluent. Two different poplar powders derived from plywood processing waste were incorporated within the photocurable formulations.

Ring‐Width Dendrochronology, Isotopic Dendrochronology and Radiocarbon Dating of Timbers From the Spire Scaffold of Salisbury Cathedral, Wiltshire, England

Archaeometry, EarlyView.
ABSTRACT Ten timbers from the spire scaffold of Salisbury Cathedral were dated using a combination of ring‐width dendrochronology, stable oxygen isotopic dendrochronology and radiocarbon dating. Seven timbers were coeval and assigned a combined empirical felling date range of 1352–1378, which was further refined to 1351–1359 (OxCal 95.4%).

Transitioning of the Chemical Industry Toward a Net‐Zero Carbon Dioxide Emission Path

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
One way to reduce the greenhouse gas footprint of the chemical industry to almost zero would be the production of the platform molecules C1‐compounds, olefins, aromatics, and ammonia by non‐fossil pathways. The rest of the chemical production chains could be essentially left unchanged, provided the process energy input is renewable.

Vast, overlooked peat, and organic soils in Brazil's Cerrado: carbon storage, dynamics, and stability

New Phytologist, Volume 250, Issue 5, Page 2946-2965, June 2026.
Summary Tropical peatlands are critical for climate mitigation due to their dual role as major carbon sinks and methane sources. In rainforests, high and stable rainfall supports peat accumulation in tropical climates. However, groundwater‐fed peatlands in seasonally dry tropical ecosystems remain poorly understood, despite their potential importance ...

Acetylation of Holocellulose in Fibrous State [PDF]

Bulletin of the Chemical Society of Japan, 1955
Abstract Acetylation in fibrous state of holocellulose, its alkali-refined product, rayon pulp and Bemberg rayon was undertaken to disclose the effect of pentosan and the structure of holocellulose. 1) Acetylation of air-dried holocellulose is roughly controlled by surface resistance regardless of various ratios depending ...

Influence of Hornification Treatment and Fiber Length on the Performance of Recycled Polypropylene Composites

Polymer Composites, Volume 47, Issue 5, Page 4793-4803, 10 March 2026.
Study of the influence of hornification treatment and jute and mallow fiber length on the physical, thermal, and mechanical properties of recycled polypropylene (PP) composites. ABSTRACT The growing accumulation of plastic waste has driven its reuse in the development of new composites, with natural fibers emerging as promising reinforcements. However,
