{"cited_by_count":1044942,"description":"This cluster of papers focuses on the catalytic valorization of lignin for the production of renewable chemicals, with an emphasis on biorefinery processes, lignocellulose fractionation, depolymerisation, and bioengineering. It explores various thermochemical methods and the use of nuclear magnetic resonance for characterization.","display_name":"Lignin and Wood Chemistry","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T11208","wikipedia":"https://en.wikipedia.org/wiki/Lignin#Valorization_and_uses"},"field_id":"22","id":"T11208","keywords":[{"display_name":"lignin","id":"lignin","score":0.2535,"url":"https://openalex.org/keywords/lignin"},{"display_name":"lignin valorization","id":"lignin-valorization","score":0.6768,"url":"https://openalex.org/keywords/lignin-valorization"},{"display_name":"lignin degradation","id":"lignin-degradation","score":0.2572,"url":"https://openalex.org/keywords/lignin-degradation"},{"display_name":"lignin structure","id":"lignin-structure","score":0.8527,"url":"https://openalex.org/keywords/lignin-structure"},{"display_name":"lignin removal","id":"delignification","score":0.2055,"url":"https://openalex.org/keywords/delignification"},{"display_name":"lignin depolymerization","id":"lignin-depolymerization","score":0.7602,"url":"https://openalex.org/keywords/lignin-depolymerization"},{"display_name":"kraft lignin","id":"kraft-lignin","score":0.6634,"url":"https://openalex.org/keywords/kraft-lignin"},{"display_name":"lignin extraction","id":"lignin-extraction","score":0.7408,"url":"https://openalex.org/keywords/lignin-extraction"},{"display_name":"lignin model compounds","id":"lignin-model-compounds","score":0.7339,"url":"https://openalex.org/keywords/lignin-model-compounds"},{"display_name":"kraft pulping","id":"kraft-pulping","score":0.6097,"url":"https://openalex.org/keywords/kraft-pulping"},{"display_name":"pulp bleaching","id":"pulp-bleaching","score":0.5393,"url":"https://openalex.org/keywords/pulp-bleaching"},{"display_name":"kraft pulp","id":"kraft-pulp","score":0.4269,"url":"https://openalex.org/keywords/kraft-pulp"},{"display_name":"wood chemistry","id":"wood-chemistry","score":0.2198,"url":"https://openalex.org/keywords/wood-chemistry"},{"display_name":"pulp yield","id":"pulp-yield","score":0.5063,"url":"https://openalex.org/keywords/pulp-yield"},{"display_name":"kappa number","id":"kappa-number","score":0.665,"url":"https://openalex.org/keywords/kappa-number"},{"display_name":"lignin biosynthesis","id":"lignin-biosynthesis","score":0.208,"url":"https://openalex.org/keywords/lignin-biosynthesis"},{"display_name":"lignin modification","id":"lignin-modification","score":0.6642,"url":"https://openalex.org/keywords/lignin-modification"},{"display_name":"black liquor","id":"black-liquor","score":0.3781,"url":"https://openalex.org/keywords/black-liquor"},{"display_name":"lignosulfonate","id":"lignosulfonate","score":0.3065,"url":"https://openalex.org/keywords/lignosulfonate"},{"display_name":"pulp brightness","id":"pulp-brightness","score":0.5881,"url":"https://openalex.org/keywords/pulp-brightness"},{"display_name":"wood pulp","id":"wood-pulp","score":0.2396,"url":"https://openalex.org/keywords/wood-pulp"},{"display_name":"oxygen delignification","id":"oxygen-delignification","score":0.7719,"url":"https://openalex.org/keywords/oxygen-delignification"},{"display_name":"lignin oxidation","id":"lignin-oxidation","score":0.6595,"url":"https://openalex.org/keywords/lignin-oxidation"},{"display_name":"organosolv lignin","id":"organosolv-lignin","score":0.7394,"url":"https://openalex.org/keywords/organosolv-lignin"},{"display_name":"alkali lignin","id":"alkali-lignin","score":0.5237,"url":"https://openalex.org/keywords/alkali-lignin"}],"legacy_keywords":["Lignin Valorization","Catalytic Transformation","Renewable Chemicals","Biorefinery","Lignocellulose Fractionation","Depolymerisation","Bioengineering","Polymeric Materials","Thermochemical Methods","Nuclear Magnetic Resonance"],"openalex_id":"https://openalex.org/T11208","source_created_date":"2024-01-23T15:27:09","source_updated_date":"2026-10-17T03:02:00","subfield_id":"2204","url":"/topics/T11208","works_api_url":"https://api.openalex.org/works?filter=topics.id:T11208","works_count":60530,"label":"Lignin and Wood Chemistry","provider":"openalex","revision":"adff6a50d90f1949","taxonomy_revision":"f050b5d4780b1289","title":"Lignin and Wood Chemistry","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36240490722936369","address_version":"morton4x16-v1","coordinates":[3,22,2204,11208],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
