Executive Statement:

A new method to generate ultra-high pressures while improving sample accessibility through laser-drilled diamond culets and plastic flow in metallic gaskets.

Description:

This innovative technology enables the generation of pressures exceeding 1 GPa by compressing a blank metallic gasket, inducing plastic flow into a laser-drilled hole at the diamond culet tip. Unlike traditional methods that restrict sample access due to metallic gaskets and anvils, this approach pushes the sample out of the gasket plane, enhancing accessibility for experimental probes such as nuclear magnetic resonance (NMR). This technique provides a versatile and improved way to pressurize samples, reducing reliance on toxic materials and complicated gasket designs.

Key Advantages:

• Improved access to pressurized samples for experimental probes like NMR and X-ray analysis.
• Eliminates the need for toxic light metals such as beryllium.
• Enables generation of pressures above 1 GPa with greater versatility.
• Reduces complications from traditional metallic gasket and anvil friction constraints.
• Can be adapted beyond diamond anvils to other pressure-generating platforms.

Problems Solved:

• Overcomes limited sample accessibility caused by metallic gaskets and anvils.
• Eliminates the skin effect and interference in RF or perpendicular detection methods.
• Addresses safety issues related to the use of toxic light metals for pressure generation.
• Provides a reliable and simpler way to generate very high pressures without split gaskets.

Marketing Opportunity:

• High-pressure scientific research, including materials science and condensed matter physics.
• Advanced nuclear magnetic resonance (NMR) experiments under extreme conditions.
• Synchrotron and hard X-ray experiments requiring improved sample accessibility.
• Development and testing of materials and chemicals under high pressure environments.
• Industrial applications involving precise control of pressure for quality and safety testing.
