Graphene Found on the Moon

 


The National Science Review has published an interesting study about graphene. Lunar samples have revealed naturally formed scant layer graphene. It is made of carbon atoms in a thin-layer structure.

The team consisted of scientists from Jilin University and the Chinese Academy of Sciences’ Institute of Metal Research.

The researchers dissected an olive shaped sample of lunar soil. The soil measured 2.9 millimeters by 1.6 millimeters. The lunar sample was taken from the Chang’e 5 mission in 2020. 

The scientists believe that 1.9% of interstellar carbon exists in the form of graphene. It’s formation is the determining factor of graphene’s shape and structure. Researchers used a spectrometer in their studies. They found an iron compound that is closely related to the formation of graphene. Scientists then used microscopic and mapping techniques to confirm that the sample contained “flakes” that have 2-7 layers of graphene. 

Researchers believe that the graphene may have been formed during volcanoes at the moon’s creation. Solar winds can mix up the moon’s soil and transform the carbon atom’s structure. 

It is believed that impact processes from meteorites led to the formation of graphene. This could have happened by high pressure environments or high temperatures. 

Graphene is becoming a super star here on Earth due to its special hallmarks in optics, electrics and mechanics. The team believes this study will help reduce the cost and expand the use of graphene. 

From the report “The mineral catalyzed formation of natural graphene sheds light on the development of low-cost scalable synthesis techniques of high-quality graphene,” it goes on to say, “Therefore, a new lunar exploration program may be promoted and some forthcoming breakthroughs can be expected.”

Mike Giradi from Stereotimes commentary on Holostage Room Treatments

I have been  friends with Mike Giradi for a few years and he has helped me test numerous designs .    I was so honored a few weeks ago when he agreed to give these Holostages a few words.  From. Mike G. The sound was a little closed in at first, but then it really opened up to prove it is another great audio product. The noise floor is greatly reduced. I am hearing details I've never heard before. When it's in the recording, the soundstage widens in all directions. The timbre of each instrument is spot on. The six Holostages installed in my room aided in the C13 alignment of air molecules to a far greater extent than the Bybee IQSE devices I had previously been using. Every instrument had greater depth, pop and presence. Listening to classical music on movie soundtracks is incredible now. The Holostages installed on my BACCH4MAC and monoblocks was the answer to what was needed. The noise floor dropped significantly in both cases resulting in greater clarity and music...

Queen Bee 🐝

  Bees hide an interesting secret. When the hive loses its queen, who alone is able to give life to the colony and maintain order in a perfectly organized society, all seems lost. The life of the hive slows down. Without new eggs, the future is lost. In a few weeks, the colony may be doomed. But the bees do not panic. Nor do they expect salvation from outside. Demonstrating extraordinary collective intelligence and profound instincts, they trigger spectacular emergency procedures, almost unimaginable in a world dominated by insects. --- ◆ The transformation begins with a simple but essential choice The worker bees choose common larvae - those who would normally be mere workers. They are nothing special. They are not born different. But their fate changes completely. They are chosen to receive a special food: royal jelly. A rare substance, produced by healthy bees, rich in proteins, vitamins and bioactive compounds. This is royal food in the purest sense of the word. The larvae fed ...

Novel Acoustic Wave Discovered

Image
  A new diffraction phenomenon was researched and published on January 14, 2025. The team was led by Tohoku University with collaboration from the Japan atomic energy agency and the RIKEN Center for emergent matter science. Surface acoustic waves (SAWs) are elastic vibrations. They travel along the surface of materials, not unlike ripples on a pond. SAWs are an important part of frequency filters used in every day devices like our cell phones. These devices change electrical signals in vibrations, or ripples. This occurs because of the piezoelectric  effect and it enables efficient signal processing. During this experiment, the team created a periodic array of magnetic nanoscale materials. The magnetic array is a sort of specialized grating that the waves passed through. The scientists were surprised. Instead of the usual symmetric defraction, the team saw something different. They observed a completely new, asymmetrical diffraction of SAWs called ‘non-reciprocal defraction’....
