New Uses for Organic Nanoparticles



 Nanoparticles are used in drug delivery, electronics, and even in water purification. The ultra small size and the ability to manipulate their properties makes them exceptionally Valuable for research advancements. When polymers made from nanoparticles are worked together, the materials functions can be improved. 

Organic nanoparticles (oNP) are far more Versatile chemically than inorganic nanoparticles. This allows for more biomedical and technical applications. In the past, the materials were limited as far as finding the correct chemical mates and understanding their mechanical properties. 

A new study by the Proceedings of the National Academy of Sciences studies the effects Of cross-linking oNP And hyperbranching. ( Hyperbranched polymers and polymer systems possessing a large number of branch points combined with relatively short chains in their molecular structures. ) These two mechanisms combine to create a very dense bonding network. 

The study also shows how to regulate both functional attributes and elastic properties. This research, also being performed in labs around the world, advances the basic understanding of the properties of oNP And the chemistry involved in large scale molecular manufacture. 

“ Through the combination of these processes, we have been able to demonstrate the capabilities of organic nanoparticles to exhibit inorganic type stiffness,” said Michael Bookstaller of the Department of Material Science and Engineering at Carnegie Mellon. 

A new way to control the properties of oNP uses atom transfer radical polarization. The  new oNP System allows for a more versatile graph modification. The resulting oNP’s are Exciting, they can be applied in direct assembly or integration into new technology. 

“ The incorporation of functionalities outlined in this work opens the door to further improve optical properties in materials,” reports Bookstaller.

This large research team will build upon the original study.  They plan on exploring fluorescence with a new class of oNP next, while measuring performance and output.

Future applications are certainly in the works!

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’....
