  - INDUSTRIAL CROPS AND PRODUCTS - Rok 2017

  Composite materials based on natural rubber were obtained by using glycerolysate (decomposition prod- uct of polyurethane) as a novel plasticizer. In order to determine the effect of various lignin content, four different filler amounts were used, namely, 5 phr (parts per 100 parts of natural rubber) of lignin (WLI5G), 10 phr (WLI10G), 20 phr (WLI20G), and 40 phr (WLI40G). The reference specimen without lignin (WLI0G) was also...

• Biocatalytic Functionalities of Lignin Peroxidase‑Based Systems in Lignin Depolymerization and Pollutants Removal from Environmental Matrices

  Publikacja

  • G. Boczkaj

  - Current Pollution Reports - Rok 2024

  Purpose of Review In the presented review, we have summarized and highlighted recent developments in the use of lignin peroxidase (LiP) to remove a variety of pollutants from water matrices. The high redox potential of LiP is underlined by its excellent catalytic functionalities in the elimination of pharmaceuticals, phenolics, dyes, polycyclic aromatic hydrocarbons (PAHs), endocrine-disrupting chemicals (EDCs), and other miscellaneous...

  - SCIENCE OF THE TOTAL ENVIRONMENT - Rok 2024

  Lignin, next to cellulose, is the second most common natural biopolymer on Earth, containing a third of the organic carbon in the biosphere. For many years, lignin was perceived as waste when obtaining cellulose and hemicellulose and used as a biofuel for the production of bioenergy. However, recently, lignin has been considered a renewable raw material for the production of chemicals and materials to replace petrochemical resources....

  Lignin-based carbon fibers (LCFs) from the renewable resource softwood kraft lignin were synthesized via oxidative thermostabilization of pure melt-spun lignin and carbonization at different temperatures from 1000°C to 1700°C. The resulting LCFs were characterized by tensile testing, scanning electron microscopy (SEM), X-ray diffraction (XRD) and confocal Raman spectroscopy. The microstructure is mainly amorphous carbon with some...

  Lignin modifying enzymes (LMEs) have gained widespread recognition in depolymerization of lignin polymers by oxidative cleavage. LMEs are a robust class of biocatalysts that include lignin peroxidase (LiP), manganese peroxidase (MnP), versatile peroxidase (VP), laccase (LAC), and dye-decolorizing peroxidase (DyP). Members of the LMEs family act on phenolic, non-phenolic substrates and have been widely researched for valorization...

  - Rok 2003

  W pracy zaprezentowano transformator standardu umożliwiający bezodbiciowe połączenie linii mikropaskowej z linią koplanarną. Konstrukcja układu opiera się na założeniu zachowania jednakowej wartości impedancji w każdym przekroju poprzecznym struktury. Zaprojektowano i przebadano dwa rozwiązania z zeskokową i ciągłą zmianą szerokości linii. Do badań numerycznych wykorzystano symulator pełnofalowy Momentum. W symulacjach uwzględniono...
