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.

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

Effects of Tree Age and Bole Section on Pulpwood of Korean Spruce (Picea koraiensis Nakai)
Korean spruce (Picea koraiensis Nakai) is one of the most important wood resources for pulp and paper industry. However, a long production cycle is required for spruce to obtain mature timber, which may negatively influence the biomass production.

Structural Colors from Ultrathin Lignin Films
Thickness‐dependent structural colors in ultrathin lignin films generate a full visible palette, tuned simply by solution concentration and spin speed. Abstract Structural colors offer a sustainable alternative to toxic pigments and dyes, yet their realization from lignin, the most abundant aromatic biopolymer, has remained elusive.

Adição de antraquinona na polpação alcalina de Eucalyptus saligna
The present work evaluated different alkaline pulping conditions for Eucalyptus saligna wood. The objective was to evaluate the influence of the anthraquinone (AQ) on the reduction of the total reduced sulfur (TRS) in the aerial emissions, by reducing ...

Smart REASSURED Sensors via Machine‐Augmented Printable On‐Paper Arrays
This perspective highlights the emerging role of pattern‐recognition, printable on‐paper sensor arrays for intelligent PoC diagnostics. It discusses how paper's inherent limitations can be overcome through surface modification and scalable printing, and how machine‐learning analysis of cross‐reactive arrays enables multiplexed, low‐cost, and REASSURED ...

Depolymerisation of γ‐Valerolactone Organosolv Lignins with Unsupported Molybdenum‐Based Catalysts
Lignins from γ‐valerolactone organosolv fractionation were depolymerised in ethanol using unsupported molybdenum catalysts. Over 90% yields of low‐molecular‐weight lignin oil were obtained with minimal char formation, yields of the aromatic monomers being 7–16 wt%.

DELIGNIFICATION OF SUGARCANE BAGASSE WITH ALKALI AND PERACETIC ACID AND CHARACTERIZATION OF THE PULP
Sugarcane bagasse was delignified with alkali and peracetic acid in a two-stage process to obtain pulps with high yield and low kappa number. The experimental results indicated that alkali pretreatment prior to peracetic acid (PAA) delignification could ...
