Biocompatibility and Biodegradability of Graphene: Advances and Scientific Evidence

Graphene and its derivatives have proven to be biocompatible and biodegradable materials, with great potential in biomedical and technological applications. Studies have validated their safety in tissues and organs, as well as their ability to be degraded by enzymes that limit their persistence both in the body and in the environment. Graphene and its derivatives are rarely found in their free form, as to harness their properties, they must be combined with three-dimensional materials or functionalized with other molecules or nanostructures to give them a specific property. This is of vital importance because such functionalizations reduce potential adverse effects, facilitating their integration into various industries and their use in sensitive applications like tissue engineering or biomedical products. Their continuous development reinforces their position as an innovative and safe material for future applications.

Graphene The Most Versatile Carbon Allotrope with Extraordinary Properties  Carbon is one of Earth’s most abundant elements and vital for living organisms. Known as the “king” of the periodic table, its chemical properties are exceptional due to an electronic structure capable of forming single, double, and triple bonds, allowing it to create up to ten million compounds.  Carbon allotropes are carbon-based materials with different molecular configurations and, consequently, unique properties. For instance, in graphite, a soft, thermally resistant, and electrically conductive material, carbon atoms form three covalent bonds in a hexagonal pattern, arranged in stacked layers loosely bonded together.  Graphite's common uses include pencils, batteries, and lubricants. Meanwhile, in diamond, an insulating material highly valued in jewelry, carbon atoms are bonded covalently in a tetrahedral structure, giving it extreme hardness used mainly for cutting tools.  Other lesser-known carbon allotropes are nanometric in size (smaller than 0.1 microns). These include fullerenes, which resemble a soccer ball and can act as semiconductors...

Carbonation and Graphene Oxide:

Carbonation and Graphene Oxide: A Solution for Reducing CO₂ Emissions In previous articles, we discussed the cement industry's impact on CO₂ emissions and the commitments made to reduce them by 2050. Today, we explore how carbonation—a process generally seen as a concrete pathology—could help offset some CO₂ emissions from cement production. What is Carbonation? In concrete, carbonation is a natural process where CO₂ from the environment reacts with moisture in the concrete, converting the alkaline calcium hydroxide in cement paste to calcium carbonate with a more neutral pH. This reaction lowers the concrete's pH from around 12–13 to approximately 9, exposing steel reinforcements to corrosion. What Affects Carbonation? Carbonation rate depends on the diffusion of CO₂ and its reactivity with the cement matrix, which is in turn influenced by the matrix's microstructure, hydration products (calcium hydroxide, calcium silicate hydrate, alkaline oxides, etc.), and pore structure (distribution, size, and saturation). Therefore, carbonation proceeds more slowly in low-permeability or dry concretes than...

Coatings Coatings industry Graphene Oxide

Advances in Fire Protection:

Intumescent coatings are paints that protect concrete and steel structures during fires by expanding and forming a foam that isolates the fire. These coatings release non-combustible gases, reducing oxygen levels and limiting fire spread. With the incorporation of graphene oxide, these coatings are expected to enhance fire protection for buildings.

The Impact of Graphene on the Plastic Industry:

Plastic originated in 1860 with the development of celluloid, a material designed to replace ivory, marking the starting point for modern plastics. While plastics are indispensable in many industries, their uncontrolled use has caused an environmental crisis, prompting the need for circular economies and recycling. Not all plastics are recyclable, and recycled plastics often lose properties during processing. Nanotechnology, particularly the use of graphene, has enhanced the performance of both virgin and recycled plastics. Even in low concentrations, graphene significantly improves the strength and durability of polymers.
