Solid State Chemistry

At UGIEL, we specialize in understanding the physico-chemical, optical, and mechanical properties of materials to optimize their interaction.
Our ultimate goal is to identify the ideal combination of these parameters to precisely meet your needs.

The benefits of solid-state chemistry include:

	Developing a wide range of colorimetric and optical properties
	Influencing the macroscopic properties of the final material
	Adapting to various sectors of activity such as semiconductors, batteries, aeronautics, pharmaceuticals, etc.

Advancing Innovation with Nanomaterials

At UGIEL, we have extensive expertise in nanostructuring and synthesizing nano-objects with customizable size, shape, and composition. We excel in developing sustainable processes to modify substrate surfaces at various scales using nanomaterials.

Benefits of nanomaterials:

	Diverse applications: Can be suspended in materials or used on surfaces
	Wide range of color palettes and potential optical effects, including the ability to trigger a color change
	Alteration of mechanical properties of materials, such as improved resistance and conductivity

Mastering Optical Effects

At UGIEL, we offer you solutions with unique visual signatures through our understanding of optics, combined with our expertise in material and nanomaterial chemistry.

The benefits of mastering optical effects:

	Customize the optical signature of a material, such as a specific shade, reflection, or depth
	Customize the absorption range of a color (e.g., a material absorbing in the visible spectrum while showing transparency or reflectance properties in another spectral range)
	Achieve mirror-like effects similar to metallization finishes

Encapsulation

At UGIEL, our expertise in encapsulation enhances the durability of pigments, providing exceptional stability when exposed to external stress.
This technology ensures that each color remains vibrant, regardless of the conditions.

Benefits of encapsulation include:

	Enhancing a color’s resistance to UV rays and high temperatures (up to thousands of degrees)
	Controlling interference phenomena for a wide range of applications, from common to specialized, such as coloring metals and alloys.

“One of the daily challenges I face involves managing our external relations, specifically accurately translating the needs of our partners. This task is very important and requires attentive listening and careful reformulation to ensure mutual understanding. It is also essential to adapt our scientific language according to the field of activity of our interlocutors.”

Aurélie LE BEULZE
CTO

“In addition to studying the chemical composition and structure of pigments, we also pay close attention to the size and morphology of the compounds based on their specific applications. This approach enables us to cater to both the ceramics and digital printing markets, where size plays a crucial role.”

Guillaume SALEK
Innovation Manager

“Recently, I had the opportunity to lead a highly innovative project focused on color. The scientific challenge was significant due to the limited available literature on the subject and the need to develop new methods and processes. As the project manager, I assembled a team to gather relevant scientific expertise and establish a robust experimental plan. These advancements have led to the development of a coloring method that is now widely adopted at UGIEL.”

Marjorie YON
R&D Engineer

“At UGIEL, our goal is to continuously develop a new generation of environmentally responsible pigments, composed solely of non-toxic and non-critical chemical elements. This approach reflects our commitment to sustainable development and our contribution to environmentally friendly technological solutions.”
