Graphene for Biomedical Applications Part II. Are graphene materials safe for humans? The family of graphene materials comprises a wide range of two-dimensional (2D) carbon nanostructures in the form of sheets that differ from each other by the particularities derived from the production method or by the innumerable functionalizations that can be performed after its obtaining. In 2022, Nature magazine, one of the most important scientific journals in the world, published a study in which

PROTECTIVE COATINGS AGAINST ELECTROMAGNETIC RADIATION The development of communication technology together with electronic devices has generated great concern regarding the electromagnetic radiation emitted by these technologies. Electromagnetic radiation is a type of electromagnetic field, that is, a combination of oscillating electric and magnetic fields, which propagates through space carrying energy from one place to another. Electromagnetic radiation can manifest itself in various ways, such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays

GRAPHENE FOR BIOMEDICAL APPLICATIONS Part I. Tissue Engineering Advances in medicine have reached levels unimagined until recently. Among them, tissue engineering has an important participation. With it is possible to combine cells, biomaterials and biologically active molecules with the aim of repairing or replicating tissues or organs with a function similar to that of the original structure. In principle, biomaterials are used as molecular scaffolds to act as a three-dimensional (3D) support or guide for

FLAME RETARDANT POLYMER COMPOUNDS WITH GRAPHENE OXIDE Polymeric compounds (engineering plastics) are widely used in the automotive, construction, food, aerospace and other sectors. Its use is based on the weight/resistance ratio, physical stability, chemical resistance and corrosion resistance. However, most polymers, due to their nature, are flammable and combustible. That is, they are materials that catch fire quickly when exposed to fire, undergoing degradation, Veo complicadoand releasing heat to later start the propagation of the

POLYMERIC MATERIALS REINFORCED WITH GRAPHENE (MASTERBATCHES) Graphene has extraordinary electrical, optical, thermal properties and high mechanical resistance. The properties of graphene are attributed to its structure in the form of two-dimensional (2D) sheets, formed by hexagonal bonded carbon atoms and a thickness of one carbon atom. Today, graphene is the most promising nanotechnological additive in the plastics industry. The incorporation of graphene and its derivatives (graphene oxide, GO) in different polymer matrices (masterbatches), have great

Use of graphene for the purification and/or desalination of water Graphene materials, that is, Graphene, Graphene Oxide (GO) and Reduced Graphene Oxide (rGO), are carbon nanostructures that, thanks to their size, area, and surface chemistry, allow the design o new three-dimensional and multifunctional materials with high probabilities. to solve the problems associated with water scarcity. For example, they are potential coagulant/flocculating agents, this is because they have a large surface area along which there are

New generation of lime paints with Graphene Although the exact date on which lime was discovered by man is not known, there are records dating back more than 14,000 years regarding its use. In the case of Mexico, it has been used since pre-Hispanic times both for construction and for nixtamalization, in ancient Greece it was used to color numerous frescoes (2800 B.C.- 1000 A.D.), the Chinese wall was built after stabilizing the soil with

GRAPHENE OXIDE COATING SYSTEMS FOR CORROSION PROTECTION Corrosion is the greatest challenge that many industries in the world must face. Currently, there is a wide variety of coatings on the market for protection against corrosion. However, most of these coatings do not have the physicochemical characteristics necessary for good performance. These coatings does not have perfect barriers and eventually fail, their chemical resistance depends on their impermeability to chemical substances, and with it their resistance

ANTICORROSIVE PRIMER WITH GRAPHINE OXIDE Corrosion is an electrochemical reaction that occurs when the metal reacts with the surrounding environment forming ferric oxide, causing the metal to lose its main characteristics of hardness and resistance. Oxygen, temperature, humidity, contaminants, gases, and the physicochemical characteristics of water are the main factors that affect the rate at which metals corrode. One of the most widely used methods to control corrosion is the application of protective (primer) coatings
