Valance Electrons and Molecular Crystals

 

Valuable insights into valence electrons can be learned using molecular crystals. Molecular crystals have low impurity concentrations, high conductivity and magnetism features. Molecular crystals have assisted in the understanding of charge ordering to superconductivity. 

The crystals have been used to learn about quantum spin liquids. Valance electrons with quantum properties are also believed to exhibit similar behavior. However, the extent magnetism plays a role in molecular crystals was unclear. 

A team released a paper in physical review B. A new team used light to analyze valence electron arrangements. They built on the studies of superconductors and quantum spin fluids.

The molecular crystal contains molecules at the vertices  Of a triangle. One valence electron is assigned to each vertex. The distribution of these electrons was experimentally determined. Irradiation of the crystal was performed, using synchrotron infrared light, along with near infrared and visible laser light.

The team analyzed the vibrational frequencies. It revealed information about valance electron locations, mobility ranges, and the stability of intermolecular distance. The team was able to study valence electron arrangements within the crystal. 

Originally, the team thought the material to be magnetic. However, about half of its valence electrons do not contribute to magnetism, but form pairs. The pairs show what appears to be a superconductivity state which is driven by charge fluctuations. 

Valance electrons that do not contribute to magnetism have hidden potential. They will lead to discoveries about superconductivity, magnetic resistance, and spin Tronics..

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’....
