"Create a professional LinkedIn background image featuring a clean, futuristic design. Use elements that reflect expertise in materials science and nanotechnology, including abstract visuals of crystalline structures, advanced polymers, and innovative lab equipment. Incorporate sleek geometric patterns, soft gradients in blues and greys, and a hint of metallic accents to convey innovation and precision. Include subtle overlays symbolizing research, process engineering, and development. The design should emphasize professionalism, creativity, and cutting-edge technology." --ar 3:2 --stylize 200
