hexagonal synthetic diamond hardness record

Hexagonal Synthetic Diamond Sets New Record for Hardness, Surpassing Natural Diamonds

Breakthrough in Diamond Synthesis by International Team

A microstructural examination of SG-50 and SG-20, as documented in Nature Materials (2025). DOI: 10.1038/s41563-025-02126-9.

An international team of physicists, materials scientists and engineers, collaborating with UmeÃ¥ University in Sweden, has successfully grown a synthetic diamond that surpasses natural diamonds in hardness. Their groundbreaking work, published in Nature Materials, involves a process that heats and compresses graphite to produce the advanced material.

Diamonds: From Aesthetic to Industrial Use

Renowned for their brilliance, diamonds have been highly valued throughout human history. Beyond their aesthetic appeal, their exceptional hardness has made them indispensable in industrial applications such as drilling. These unique properties sustain their high market value, prompting scientists to develop synthetic alternatives. Today, a wide range of lab-grown diamonds is commercially available.

The Quest for Harder Diamonds with Hexagonal Lattice Structures

Scientists have long sought to create harder diamonds by engineering hexagonal lattice structures instead of the conventional cubic formations found in both natural and synthetic diamonds. However, previous efforts have yielded hexagonal diamonds that were either too smaller or lacked the necessary purity for practical applications.

New Method for Growing Synthetic Hexagonal Diamonds

In an effort to refine diamond synthesis, the research team devised a process that subjected graphene to extreme heat within a high-pressure chamber. By optimizing the experimental settings, they successfully grew synthetic diamonds with a hexagonal lattice.

Extraordinary Properties of the New Hexagonal Diamond

Exceptional Durability and Thermal Stability

The group's initial synthesized diamond, measuring in the millimeter range, exhibited remarkable durability under 155 GPa of pressure and maintained thermal stability up to 1,100°Csignificantly surpassing natural diamonds, which typically endure pressures between 70 and 100 GPa and temperatures up to 700°C.

Potential Industrial Applications for Hexagonal Synthetic Diamonds

According to the researchers, diamonds produced through this technique are not intended for ornamental use but rather for industrial applications such as drilling and machining. Additionally, they highlight potential uses in data storage and thermal regulation.

NASA chile scientists comet 3i atlas nickel mystery

NASA and Chilean Scientists Study 3I/ATLAS, A Comet That Breaks the Rules Interstellar visitors are rare guests in our Solar System , but when they appear they often rewrite the rules of astronomy. Such is the case with 3I/ATLAS , a fast-moving object that has left scientists puzzled with its bizarre behaviour. Recent findings from NASA and Chilean researchers reveal that this comet-like body is expelling an unusual plume of nickel — without the iron that typically accompanies it. The discovery challenges conventional wisdom about how comets form and evolve, sparking both excitement and controversy across the scientific community. A Cosmic Outsider: What Is 3I/ATLAS? The object 3I/ATLAS —the third known interstellar traveler after "Oumuamua (2017) and 2I/Borisov (2019) —was first detected in July 2025 by the ATLAS telescope network , which scans he skies for potentially hazardous objects. Earlier images from Chile's Vera C. Rubin Observatory had unknowingly captured it, but ...

bermuda triangle rogue waves mystery solved

Bermuda Triangle Mystery: Scientist Claims Rogue Waves May Explain Vanishing Ships and Aircraft for decades, the Bermuda Triangle has captured the world's imagination, often described as a supernatural hotspot where ships vanish and aircraft disappear without a trace. From ghostly ships adrift to unexplained plane crashes, this stretch of ocean between Bermuda, Puerto Rico and Florida remains one of the most infamous maritime mysteries. But now, Dr. Simon Boxall, an oceanographer at the University of Southampton , suggests the answer may not be extraterrestrial at all. Instead, he argues that the truth lies in rogue waves — giant, unpredictable surges of water capable of swallowing even the largest ships within minutes. The Bermuda Triangle: A Legacy of Fear and Fascination The Bermuda Triangle has inspired decades of speculation , with theories ranging from UFO abductions to interdimensional rifts. Popular culture, documentaries and countless books have kept the legend alive, of...

nist breakthrough particle number concentration formula

NIST Researchers Introduce Breakthrough Formula for Particle Number Concentration Understanding the number of particles in a sample is a fundamental task across multiple scientific fields — from nanotechnology to food science. Scientists use a measure called Particle Number Concentration (PNC) to determine how many particles exist in a given volume, much like counting marbles in a jar. Recently, researchers at the National Institute of Standards and Technology (NIST) have developed a novel formula that calculates particle concentrations with unprecedented accuracy. Their work, published in Analytical Chemistry , could significantly improve precision in drug delivery, nanoplastic assessment and monitoring food additives.
