Summary: Lignocellulosic nanofibrils (LCNFs) were isolated from poplar sawdust using a sustainable preparation approach. The LCNFs showed a network structure with high crystallinity, good thermal stability, and fine dispersibility in water. Lignocellulose nanopapers (LCNP) prepared using the LCNFs exhibited superior mechanical performance and excellent UV-blocking function. This work offers an optimized strategy for valorization and full utilization of low-value poplar sawdust into value-added LCNFs and LCNP.

Summary: Biomass-mediated modification in zeolite synthesis shows potential in creating new porous structures and improved catalyst properties. This study prepared hierarchical ZSM-5 catalysts through desilication and lignin-mediated reassembly, modifying their physicochemical properties. The hierarchical structure with increased acidity directed by lignin addition demonstrated better product yields and reduced solid residue compared to microporous ZSM-5, enhancing the conversion of biomass and plastic feedstocks.

Summary: A one-pot strategy using electroactive melanin lignin nanoparticles has been developed for the synthesis of bioactive hydroxytyrosol esters. The strategy involved the co-immobilization of lipase and tyrosinase on the nanoparticles, and utilized sustainable 2-methyltetrahydrofuran as the reaction solvent. The presence of the nanoparticles improved the overall activity of tyrosinase, resulting in the selective synthesis of desired catechols.

Summary: Current therapy against melanoma relies on surgical treatment or conventional drug therapy, but these methods are often ineffective due to drug resistance. Chemical hybridization has emerged as an effective strategy to overcome drug resistance. In this study, a series of molecular hybrids were synthesized combining artesunic acid with coumarins. The novel compounds showed lower cytotoxicity and higher activity against metastatic melanoma than standard drugs. Further tests were conducted to explore the mode of action and pharmacokinetic profile of selected compounds.

Summary: Chitosan and lignin mixed nanoparticles were prepared using layer-by-layer and nanoprecipitation methodologies as sustainable biosensor platforms. The nanoparticles exhibited effective chemophysical and electrochemical properties, depending on the preparation methodology, chitosan molecular weight, and lignin type. HOMO-LUMO energy gap calculations indicated the existence of structure-activity relationships between electrochemical responsiveness and the order and orientation of lignin aromatic subunits and chitosan chains in the nanodevices.

Summary: This work was conducted as part of a master's thesis on the conservation of a contemporary artwork by surrealist artist Roberto Sebastian Matta. The study focused on a large triptych created in 1974 using pastels on tracing paper adhered onto canvas. The main issue identified was the strong acid hydrolysis of both the paper and canvas supports. The intervention primarily involved deacidification treatments, comparing traditional substances like calcium propionate in an alcoholic solution to innovative methods such as nanostructured calcium hydroxide in isopropyl alcoholic solution.
