New Study: Electrical Fields Boost Graphene’s Potential by Heartsound Audio


Researchers at the National Graphene Institute are changing how the world will harness energy and compute information. A recent study was published in nature magazine, revealing how electric field effects can selectively speed up electro chemical processes in graphene. 


Electrochemical processes are important in renewable energy materials, like batteries, fuel cells and electrolyzers. Typically their efficiency is hindered by slow reactions or unwanted side effects. Traditional techniques have focused on new materials, but not without challenges.

Dr Marco Lozada-Hidalgo and a team of researchers in Manchester, England have had a significant breakthrough. They have successfully decoupled the inseparable link between charge and electric field within graphene electrodes. This separation enables unprecedented control over electro chemical processes in the material. The study focus on proton related processes, fundamental for hydrogen catalyst and electronic devices.
 Specifically, the team examine two proton processes in graphene. 
PROTON TRANSMISSION: This process is important for developing new hydrogen catalyst and fuel cell membranes.
PROTON ADSORPTION: Hydrogeneration important for electronic devices like transistors, the process switches  Graphene’s conductivity on or off.
Traditionally, both processes were coupled in graphene  devices, making it a challenge to control one Without imparting the other. Researches have managed to decouple these processes. It was unexpected and presents a new method Of understanding the electrochemical process.
Dr Yangming Fu reports “ Control of these processes, gives our Graphene devices dual functionality as both memory and logic gate.” 
This theory will pave the way for computing networks that run on protons and create new low energy, analog computers.

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’....
