New Nanomaterial Cellulose MXene



 The search for sustainable materials has led scientists to a new class of composites. These composites are called cellulose-MXene.  It was initially developed at Nanjing Forestry University and The University of Bayreuth. The new material combines cellulose with MXene. MXene is a grouping of two dimensional transition metal carbides, carbonitrides, and nitrides. The researchers published their work in the journal Bioresouces and Bioproducts.

Cellulose is made from diverse sources like wood pulp. Bacterial nanocellulose is noted for it's compatibility with living organisms and it's biodegradability. Because it is so widely available and sustainable, it's the perfect candidate for the creation of composite materials. By mixing it with MXene, scientists hope to create a material with enhances performance characteristics. 

MXene's are remarkable for several reasons. They have high hydrophilicity and non linear absorption coefficient. The MXene family is noted for its electronic conductivity. It's currently being used in biomedical applications, energy storage, sensors, separation and even catalysts. 

The new material that the scientists in the study created shows extraordinary characteristics, including biocidal, photothermal and even piezoelectric characteristics. This makes the new material satisfactory for a wide variety of uses. 

The team has made a significant breakthrough. They have created a process to fully use the MXene precursors. They have created a smart pressure sensor and multi-protection materials. These materials display superior antibacterial activity,  pressure sensitivity and efficient electromagnetic interference shielding. 

Scientists were able to grow zeolitic imidazolate framework-8 (ZIF-8) on the surface of the cellulose nano fibers. This enhances the materials biocidal activity and electromagnetic shielding. 

The study shows that by adding MXene with cellulose materials gives them multi-functional properties. New applications can include wound dressings, desalination through solar energy and also pressure sensors.

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’....
