New Environmentally Friendly Glue

 


Research was recently published in the journal Science from the university of California, Berkeley. 

Scientists have discovered an environmentally friendly adhesive polymer. The team used an electrophilic Stabilizer to stop a kind of fatty acid from depolymerizing. This enabled the researchers to use it as an adhesive. 

Zhibin Guan is a chemist at the University of California, Irvine and outlined some of the work that is being studied.

Guan reports that polymer adhesives are used in many applications. They are each designed for a specific use. An example of this is wood glue- It cannot be used effectively in other contexts. Also, Guan reports that many adhesives are Hazardous to both plants and animals. This creates a rising environmental problem.

The goal was to develop a sustainable polymer adhesive that can be used in the medical and non-medical field, having a wide variety of applications. 

Scientists used a-lipoid acid (aLa). This is an organic fatty acid that breaks down naturally. They found that using an electrophilic stabilizer stops polymers from breaking down. An entire new generation of adhesives is born!

Researchers found that aLa Adhesive can be used for tissue mending, but also for wood and even metal. The new adhesives had been approximately the same strength as petroleum-based adhesives. Many of them are even self healing, so they have immediate implications in the medical field. The scientists have also developed a closed loop recycling process. They can make new adhesives out of the old by adding aqueous materials.

Any steps taken towards greening up the medical field are considered big!

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’....
