Assembly of electrochemically active materials into paper‐based electrodes opens up new opportunities for flexible energy storage devices. Yat Li and co‐workers review the recent advances in the synthesis of paper‐based electrodes, including paper‐supported electrodes and paper‐like electrodes in article 1700107. Their structural features, electrochemical performances and implementationas electrodes for flexible energy storage devices are highlighted and discussed.

Este estudio analiza desde el punto de vista gerencial y ambiental, el sistema de información empresarial en la problemática de gestión de desechos en papel, plástico y pilas dentro del contexto comunitario de la Provincia de Tungurahua- Ecuador, en donde se utilizó un procedimiento estadístico descriptivo en la investigación. Se indagó a 385 empresas de Tungurahua de la base de datos de la "Cámara de Comercio de Ambato", encuestando a sus responsables relacionados con temas ambientales. Entre los aspectos relevantes del estudio, se ponen de manifiesto: a) el 41 % de las empresas encuestadas percibe que los elementos que administra un sistema de información empresarial son identificar procesos, métodos y herramientas en la gestión de residuos para satisfacer las necesidades de los consumidores, lo que indica que la mayoría no identifica una definición de lo que es un sistema de información; b) por otro lado, se percibe la falta de concienciación ambiental, ya que solo el 20 % de las empresas de Tungurahua indican que debe existir una mayor responsabilidad con respecto a la gestión ambiental. This paper analyzes from the management and environmental point of view, the business information system in the issue of paper, plastic and batteries waste management within the community context of the province of Tungurahua, Ecuador, where a descriptive statistical method was used in this study. The research was conducted on 385 companies Tungurahua database of the "Chamber of Commerce of Ambato," surveying its related environmental issues responsible. Among the relevant aspects of the study, it must be highlighted: a) 41% of the companies perceived that the elements managed by a business information system are to identify processes, methods and tools in waste management to meet the needs of consumers, indicating that the majority does not identify a definition of what is an information system; b) on the other hand, the lack of environmental awareness is perceived as only 20% of Tungurahuan companies indicate that there must be a greater responsibility for environmental management. Cette étude analyse du point de vue des gérants et de l’environnement, le système d'information d'entreprise dans le problème de la gestion des déchets en papier, en plastique et des batteries dans le cadre de la communauté de la province de Tungurahua, Equateur, où une méthode statistique descriptive a été utilisée dans la recherche. Cette recherche a été conduite sur 385 entreprises de la base de données de Tungurahua "Chambre de Commerce d’Ambato", avec une enquête de questions environnementales aux responsables de ces entreprises. Parmi les aspects pertinents de l'étude, on doit mentionner: a) 41% des entreprises interrogées, percoivent le système d'information d'entreprise avec les processus, méthodes et outils de gestion des déchets pour répondre aux besoins des consommateurs, indiquant que la majorité ne permet pas d'identifier une définition de ce qu'est un système d'information; b) d'autre part, la manque de sensibilisation à l'environnement est perçu car seulement 20% des entreprises indiquent qu’en Tungurahua doit y avoir une plus grande responsabilité de la géstion de l'environnement.

Paper‐based materials are emerging as a new category of advanced electrodes for flexible energy storage devices, including supercapacitors, Li‐ion batteries, Li‐S batteries, Li‐oxygen batteries. This review summarizes recent advances in the synthesis of paper‐based electrodes, including paper‐supported electrodes and paper‐like electrodes. Their structural features, electrochemical performances and implementation as electrodes for flexible energy storage devices including supercapacitors and batteries are highlighted and compared. Finally, we also discuss the challenges and opportunity of paper‐based electrodes and energy storage devices.

Permalloy nanoparticles containing bacterial cellulose hydrogel obtained after reduction was compressed into a xerogel flexible sheet by hot pressing at 60 ° C at different pressures. The permalloy nanoparticles with an ordered structure have a bimodal size distribution centered around 25 nm and 190 nm. The smaller nanoparticles are superparamagnetic while the larger particles are ferromagnetic at room temperature. The sheets have a room temperature magnetisation of 20 emug-1 and a coercivity of 32 Oe. The electrical conductivity of the flexible sheets increases with hot pressing pressure from 7 Scm-1 to 40 Scm-1 at room temperature.
