Superheavy Nuclei

 


Scientists have made important advances in the ongoing search to create new, long lasting, superheavy nuclei. These are ‘double magic’ nuclei. They are characterized by a precise number of protons and neutrons to form a very stable configuration. These nuclei are extremely resistant to decay. 

The study will provide understanding into the forces that bind atoms together.

The research was published in the journal Nuclear Science and Techniques. It’s one step closer to the “Island of Stability.” This is an area in the nuclei chart where some nuclei might exist for much longer than those previously created.

Professor Feng-Shou Zhang has theorized reactions between elements that could be used in the double magic nuclei. One reaction is between a radioactive, calcium isotope and a plutonium target. The scientists are hoping to create the predicted double magic nuclei 298Fl. 

Scientists expect these elements can be made and remain stable. It’s possible they have unique properties that can be useful in many different scientific fields. 

The researchers used an advanced theoretic model. They studied heavy ion collisions. The researchers chose the correct combination of projectiles and targets. This lays out a clear path for all future experiments.  

Despite all the progress, there are still problems. The first issue is improving the efficiency of the reactions.

This work does two important things. It advances the field of nuclear physics, and it set the stage for all future discoveries.

The research was the collaboration of the national laboratory of ion accelerator of Lanzhou, Beijing Academy of science and technology, Guangxi University and Beijing University.

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 🐝

Image
  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’....
