Paragraph starter

Research indicates that ultrafast laser surface texturing offers a promising, environmentally friendly approach to enhance the hydrophobicity of materials like marble. By precisely controlling laser parameters, it is possible to create micro- and nanoscale surface features that repel water, achieving contact angles well above 90 degrees, while maintaining the original aesthetic qualities of the material, such as color and gloss. This technique avoids the use of chemicals and the generation of toxic waste, positioning it as a sustainable alternative to traditional surface treatments in applications ranging from architectural conservation to product design.
