Neutrons to Measure Temperatures in Electronics



 Batteries and LEDs are just two small examples of electronics in our daily lives. There is a continuous thrust to make them even more efficient and reliable. Because these devices are increasingly sophisticated, recording reliable temperature measurements inside an object has become exigent. 

Measuring a device’s temperature is important for tracking performance and designing the materials of which it’s made. A new study from Osaka University is cutting edge. Neutrons have been used to measure temperatures quickly and accurately. This will lead to improvements for all kinds of electronics.

This new method of estimating temperature inside the device uses a technique called Neutron Resonance Absorption (NRA). By looking at neutrons being absorbed by atomic nuclei at certain energy levels, the effects of the materials can be inferred.   

Scientist generated high intensity laser beams to create neutrons. The neutrons were slowed to very low energy levels And passed through a sample. It successfully returned details About the material and temperatures with ultra fast speed.

“ This technology makes it possible to instantaneously and accurately measure temperature,” states Zechen Lan, Head researcher.  “As our method is nondestructive, it can be used to monitor devices like batteries and semiconductor devices.”

The NRA measurements are created with a single pulse of neutrons. The new technique can obtain data from 100 nanoseconds or 1/10 a millionth of a second. The results results are near instant, so they can be measured in nearly real time, with detailed analysis. 

Another huge plus to the project, it’s about 1/10 of the size of similar equipment. This means laboratories elsewhere can easily install their own version.

The ability to measure the operating temperatures of devices and the devices materials will advance all understanding of function! This will lead to future Improvements in all electronic devices!

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’....
