A Hydrogen Bond Discovery



Hydrogen bonds can enhance the versatility and phosphorescence  of organic luminescent materials. This will forever change the anti-counterfeiting, imaging and electronic fields.

A team from the University of St. Andrews is researching hydrogen bonds. It is being led by Dr. Sen Wu, Dr. Tao Wang and Professor Eli Zyman-Colman from the School of Chemistry at St. Andrews. The study was recently published in CCS Chemistry. It shows that hydrogen bonding can improve the performance of organic room temperature phosphorescence (RTP) materials.By using hydrogen bonds, light emitting materials could reach new heights in data storage and anti-counterfeiting technologies. 

RTP happens when materials emit light after being excited. This creates a long term luminescent effect. Many different RTP materials have been developed. However, creating high efficiency RTP is a challenge due to its extremely complex processes.

Hydrogen bonding is an important interaction between molecules. It is considered essential for developing these materials. Previous studies had not yet confirmed hydrogen's role. 

Scientists have recently discovered hydrogen bonding activates RTP. They compared the different effects in varying host materials. The researchers showed how these bonds can influence the brightness and stability of RTP. The scientists have made it possible to fine tune these features.

Professor Zysman-Colman summarizes, " Through systematic structural and photophysical investigations, the work has elucidated the universal role hydrogen bonding has in triggering RTP by investigating the properties in a diverse range of hosts that either can hydrogen bond or not with the guest molecule. The findings open new possibilities for the practical use of RTP materials, including luminescent origami, anti-counterfeiting measures, and even light-based data writing techniques. This study not only deepens our understanding of how RTP works but also highlights new ways to control and optimize these fascinating materials for a range of cutting edge applications."

The future is bright! (LOL!)

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’....
