In the town of Calera y Chozas (Spain), five mass graves containing the remains of 28 individuals were discovered during a 2012 excavation. The witnesses and historical evidence indicated that the body of the last Republican mayor of the town, Felipe Fernández Varela, who had died in September 1939, was located in the mass grave designated as no. 1.

- * The study compared CNCs derived from enzymatic methods (EnCNCs) with those from sulfuric acid hydrolysis (AcCNC), finding that EnCNCs had better thermal stability and crystallinity.
- * Incorporating EnCNCs into WBPUs enhanced their thermomechanical stability, mechanical properties, and made them effective for applications like paper coatings and nanocomposite mats while preserving fiber structure.

View Article and Find Full Text PDFSodium alginate, a biopolymer extracted from brown algae, has shown great potential for many applications, mainly due to its remarkable biocompatibility and biodegradability. To broaden its fields of applications and improve material characteristics, the use of nanoreinforcements to prepare nanocomposites with enhanced properties, such as carbonaceous structures which could improve thermal and mechanical behavior and confer new functionalities, is being studied. In this work, graphene oxide was obtained from graphite by using modified Hummers' method and exfoliation was assisted by sonication and centrifugation, and it was later used to prepare sodium alginate/graphene oxide nanocomposites.
