    "device_name": "Boric Acid Lubricant",
    "goal": "Improve lubricity of low-sulfur fuels and lubricants to reduce engine wear and increase fuel efficiency.",
    "problem_addressed": "Low-sulfur diesel and gasoline fuels lack sufficient lubricity, causing high friction, wear of fuel pumps and injectors, and reduced engine efficiency.",
    "concept_summary": "Adding boron-containing compounds such as boric acid, borax, boron oxide, or nanometer-sized boric acid powders to fuels or lubricants (often dissolved in an alcohol solvent) creates a boron-enriched fuel/lubricant that reduces friction, lowers wear scar diameter, and can improve fuel economy by 4-5 %.",
