Population Growth and Land Use Dynamics along Urban–Rural Gradient [PDF]

open access: yes
In this study we apply a spatial conditional logit model to determine factors influencing land cover change in three contiguous counties in West Georgia between 1992 and 2001 using point (pixel) based observations of land characteristics.

The Formation of Covalent Linkages in Lignocellulosic Biomass via the Oxocarbenium Intermediate

open access: yesChemPhysChem, Volume 27, Issue 4, 25 February 2026.
Density functional theory models show that the hydrated and acidic hemicellulose matrix in lignocellulosic biomass can generate oxocarbenium ions. These reactive intermediates can participate in the stable formation of glycosidic lignin‐carbohydrate covalent linkages, promoting recalcitrance in plant biomass.

U.S. BIOMASS SUPPLY FOR ELECTRICITY GENERATION: CLIMATE POLICY IMPLICATIONS AND CARBON NEUTRALITY [PDF]

open access: yes
This paper investigates three important energy and climate policy issues: (1) the availability of biomass for electricity generation (i.e., supply), (2) climate policy effects on this supply, and (3) the net greenhouse gas reduction when biomass is used ...

Ozonolysis of Lignin: From Extensive Degradation to Selective Ring‐Opening Oxidation

open access: yesChemSusChem, Volume 19, Issue 4, 25 February 2026.
Despite its potential as a renewable feedstock, lignin, a major component of plant cell walls and a by‐product of the pulp and paper industry, has long been underutilized. Historically, pulp mills employed ozonolysis, a powerful oxidative process, to delignify cellulosic fibers and break down lignin.

Fractionation of AquaSolv Omni Biorefinery Lignins and Their Application in Antioxidant and Ultraviolet‐Protective Films

open access: yesChemSusChem, Volume 19, Issue 4, 25 February 2026.
Sequential fractionation of AquaSolv Omni biorefinery lignins allowed to obtaining of lignin/lignin–carbohydrate complexes with potent antioxidant and Ultraviolet‐shielding properties, showing adaptable glass transition behavior that can be tailored according to the selected application requirements. Lignin and lignin–carbohydrate complexes (LCCs) were

A study of the importance of secondary reactions in char formation and pyrolysis : a dissertation presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Process Engineering at Massey University, Manawatū, New Zealand [PDF]

open access: yes, 2016
Anthropogenic climate change, caused primarily by excessive emissions of carbon dioxide, has led to a renewed interest in char, the solid product of pyrolysis. When applied to soil as biochar it can both sequester carbon and improve soil function.

Tailoring Biomass‐Derived Organosolv Lignin Derivatives for High‐Capacity Adsorption of Rhodamine B

open access: yesChemSusChem, Volume 19, Issue 4, 25 February 2026.
Organosolv lignin derivatives modified with phenolic compounds were synthesized via a one‐step lignin‐first approach and evaluated as renewable adsorbents for removing Rhodamine B dye from water. Among them, resorcinol‐modified lignin showed the highest adsorption capacity (101 mg g−1), driven by high surface area, pore volume, and accessible hydroxyl ...
