Pyrolysis Study of Cinnamaldehyde Model Compound with Analytical Py-gc×gc-fid/tof-ms

open access: yesChemical Engineering Transactions, 2020
Aldehyde-type lignin monomers like hydroxycinnamaldehydes are important monomers in plants downregulating the enzyme activity of cinnamyl alcohol dehydrogenase or catechol-O-methyltranferase. Cinnamaldehyde (CA) is the simplest aldehyde-type lignin model

Expression of a bacterial 3-dehydroshikimate dehydratase reduces lignin content and improves biomass saccharification efficiency. [PDF]

open access: yes, 2015
Lignin confers recalcitrance to plant biomass used as feedstocks in agro-processing industries or as source of renewable sugars for the production of bioproducts. The metabolic steps for the synthesis of lignin building blocks belong to the shikimate and

Lignin engineering in forest trees [PDF]

open access: yes, 2019
Wood is a renewable resource that is mainly composed of lignin and cell wall polysaccharides. The polysaccharide fraction is valuable as it can be converted into pulp and paper, or into fermentable sugars.

Co‐Reactivity of Fragrances and Fragrance‐Markers in Patients With Positive Patch Tests to Chinese and Brazilian Propolis

open access: yesContact Dermatitis, Volume 94, Issue 5, Page 482-487, May 2026.
In this study, the patterns of co‐reactivity to the four fragrance markers present in the European baseline series ( Myroxylon pereirae resin [balsam of Peru], colophonium, fragrance mixes 1 and 2) and to the fragrances limonene and linalool hydroperoxides in patients allergic to Brazilian propolis were investigated.

Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

open access: yesAdvanced Engineering Materials, Volume 28, Issue 7, 8 April 2026.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Sodium silicate promotes wound healing by inducing the deposition of suberin polyphenolic and lignin in potato tubers

open access: yesFrontiers in Plant Science, 2022
Wound healing is a postharvest characteristic of potato tubers through accumulating suberin and lignin, which could reduce decay and water loss during storage.

Beyond Brown: Lignin's Emerging Role in Structural Color

open access: yesAdvanced Optical Materials, Volume 14, Issue 13, 3 April 2026.
Lignin, long regarded as a brown industrial byproduct, is emerging as a sustainable platform for structural color. This Perspective highlights how lignin's refractive index, intrinsic absorption, and nanoscale assembly enable tunable photonic responses in colloidal and thin‐film architectures, and outlines design strategies to advance scalable, bio ...
