Esterified lignins from Pinus caribaea as bentonite-dispersing agents
(Cambridge University Press, 2020)
Atomic force microscopy (AFM) investigation of Langmuir-Blodgett (LB) films of sugar cane bagasse lignin
(Walter De Gruyter & CoBerlinAlemanha, 2000)
Monodisperse lignin fractions as standards in size-exclusion analysis Comparison with polystyrene standards
(ELSEVIER SCIENCE BV, 2009)
The difficulty of preparing monodisperse lignin fractions on a large scale is a limiting factor in many applications. The present paper addresses this problem by examining the properties and size-exclusion behavior of ...
Thermal Characteristics of Lignin Residue from Industrial Processes
(North Carolina State Univ Dept Wood & Paper Sci, 2014)
Biodegradation of acidolysis lignins from Chilean hardwoods by the ascomycete Chrysonilia sitophila
(SpringerNew YorkEUA, 1997)
Recent approaches and future trends for lignin-based materials
(2017-09-22)
Known as the main source of aromatic compounds in nature, lignin possesses heterogeneous composition which has high potential to be used in many industrial purposes. Lignin has been used as retardants of fire, thermal ...
CHEMICAL AND PHYSICO-CHEMICAL CHARACTERIZATION OF LIGNINS OBTAINED FROM ETHANOL-WATER FRACTIONATION OF BAGASSE
(NORTH CAROLINA STATE UNIV DEPT WOOD & PAPER SCI, 2011)
Organosolv lignins can replace petroleum chemicals such as phenol either partially or totally in various applications. Eight lignins, seven of which corresponded to the ethanol-water fractionation of bagasse and the other ...
Cellulose-Lignin interactions during slow and fast pyrolysis
(ELSEVIER, 2018)
Mapping the lignin distribution in pretreated sugarcane bagasse by confocal and fluorescence lifetime imaging microscopy
(BioMed CentralLondon, 2013-04)
Background: Delignification pretreatments of biomass and methods to assess their efficacy are crucial for biomassto- biofuels research and technology. Here, we applied confocal and fluorescence lifetime imaging microscopy ...
Structural, morphological, and thermal characterization of kraft lignin and its charcoals obtained at different heating rates
(Iop Publishing Ltd, 2018)
Biomass is a renewable resource that is becoming more import due to environmental concerns and possible oil crisis. Thus, optimizing its use is a current challenge for many researchers. Lignin, which is a macromolecule ...
