Procuring Copper Oxide Nanoparticles through Plants

 

Researchers have found a green method for obtaining copper oxide from the Noni plant. Morinda citrifolia Is from Asia and the leaf extract is currently being used in this cutting edge research.

The copper oxide nanoparticles Display bactericidal Properties. Moreover, antibacterial activity depends on the physical properties of the nanoparticles, size, structure, and concentration of copper oxide.

Biochemists are studying ways to acquire these particles. Chemical and physical methods are widely known, but require the use of highly toxic chemicals. The new method is to use the biological approach, i.e. nanoparticles from plants, bacteria or fungi. 

A RUDN biochemist, along with scientists from India, Korea and Saudi Arabia have reported producing copper oxide nanoparticles from Noni and reported it in Scientific Reports. 

“ copper oxide nanoparticles are of interest in many areas of science. Biosynthetic nanoparticles are produced through the biological process from bacteria, fungi, or plant extracts. The importance of such nano particles lies in their potential for sustainable, effective, and bio compactible solutions in healthcare and environmental protection, as well as in natural science and energy.” reports Alexandre Vetcher, Deputy Director of the Nanotechnology Center at RIDN University. 

Noni grows in the south Pacific and is a tall plant with edible fruits. The extract used was made from the leaves and mixed with a solution of copper sulfate. A catalyst, sodium hydroxide was also used. The role of Noni was to stabilize the nanoparticles used.

The result was stable spiral copper oxide nanoparticles ranging From 20 to 50 nm — and they were found to be as antibacterial as chloramphenicol. 

“ The resulting copper oxide nanoparticles can be used in biomedicine, the production of fuel cells, batteries, and food storage.” 

The future: More research is needed to minimize toxicity, while maintaining the nanoparticles biological effectiveness. Hopefully this will add to the biomedical use of nanoparticles.

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’....
