Thermal Stabilization of Chitosan Yarn for Carbon Fiber Production

Journal of Applied Polymer Science, Volume 143, Issue 13, April 5, 2026.
This study explores chitosan, a biopolymer derived from chitin, as a renewable precursor for carbon fiber production. The authors demonstrate that chitosan fibers can be successfully stabilized under controlled thermal conditions in air and nitrogen.

Liquefaction o Kraft Lignin at Atmospheric Pressure

Journal of Renewable Materials, 2019
Kraft lignin was liquefied using polyethylene glycol #400 (PEG) and glycerol (G) in a weight ratio of 80/20 (w/w) and sulphuric acid (SA) as catalyst under atmospheric pressure at 160ºC. The three independent variables: reaction time (60, 80 and 100 min), percentage of lignin (15, 20 and 25%, w/w), and catalyst concentration (0, 3 and 6%, w/w), were ...

Revisiting acidulation for tall oil and lignin manufacturing

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1677-1691, April 2026.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Quality of Forage Cactus Silage with the Addition of Hay from Forages Adapted to the Semiarid Region

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
This study investigated the effects of including hays from different forages adapted to the semiarid region on the forage cactus (Opuntia fícus‐indica (L.) Mill) silage quality. A completely randomized design, with five treatments was used: pure forage cactus and forage cactus associated with 30% hay from gliricidia (Gliricidia sepium), pornunça ...

Preparation of High‐Pressure Laminate With Bio‐Based Fructose‐HMF‐Amine Impregnation Resin

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
This study demonstrates the use of a resin made from renewable carbohydrates, free from phenol and formaldehyde, for impregnating recycled kraft paper to produce high‐pressure laminates. The resulting bio‐based laminate samples match the mechanical performance of conventional phenol‐formaldehyde‐based samples, highlighting their potential to replace ...
