Digital control of feedback phase to control radiation damping in water: a project I started from level zero and finally completed. Now the Bruker AU program is capable of finding the radiation damping suppression phase fully automatically. #NMRchat #NMR

Here is the link to the talk about PyOR, which I gave at the 105th Global NMR Discussion meetings: youtu.be/S45ps8uQJcc #NMR #PyOR #NMRchat

Finally, the digitization of the Radiation damping control unit is done. Bruker AU program for automating NMR experiments by digitally controlling the radiation feedback field phase. #NMR #NMRchat

Interested to know about PyOR (Python On Resonance)? Attend the 105th Global NMR meeting. Title: PyOR: A Versatile Magnetic Resonance Simulator for Learning and Teaching Time: Tuesday, September 9th, 11:00 AM Boston/ 5:00 PM Paris/ 8:30 PM Delhi Link: nyu.zoom.us/j/91419770855 #NMR #NMRchat

Finally, the 16-bit digital-to-analog converter (DAC714) is working. In a few weeks, Bruker Topspin will take control of the DAC via FPGA (UART and SPI). And then the phase shifter of the radiation damping control unit. #NMR #FPGA #NMRchat

The FPGA programming is completed for controlling a voltage-controlled phase shifter via a 16-bit DAC (DAC714) using SPI for a digitalized radiation damping control unit for doing feedback-based Maser/Raser experiments. ##NMR #NMRchat

I will be presenting a poster at EUROMAR 2025 in Oulu on the topic of NMR masers and PyOR: “NMR Masers: From Single-Mode DNP Hyperpolarization at 1.2 K to Multimode Masers in Solution via Electronic Control of Radiation Feedback.” poster: HYP 008 #NMR #NMRchat

Here is my second post about "Simulating a Spectrum" with PyOR, on MARQUISE - Magnetic Resonance Quantum Information Science and Education (quantum-resonance.org): quantum-resonance.org/introduction... Follow MARQUISE: www.linkedin.com/company/marq... #NMR #NMRchat

Here’s a one-page story. If you find it meaningful, share it with a friend pursuing a PhD who might be going through some small struggles. #NMR #PHD #NMRchat

Hello everyone! I’m excited to share that I had the wonderful opportunity to write about PyOR (Python On Resonance) through MARQUISE — a platform by learners, for learners in Magnetic Resonance Quantum Information Science and Education. quantum-resonance.org/introduction... #NMR #NMRchat

For anyone interested in implementing serial and VISA communication in Bruker's AU programs to automate NMR experiments with external instruments, here are the programs I made: 1. Serial: github.com/VThalakottoo... 2. Visa: github.com/VThalakottoo... #NMR #NMRchat

Here is an example of magic angle spinning (CSA) in PyOR. The next implementation will be hyperpolarization + EPR. Visit GitHub: github.com/VThalakottoo... Example MAS: github.com/VThalakottoo... #NMR #NMRchat

Python On Resonance (PyOR) "Everybody can simulate NMR" Here is the PyOR's documentation page: vthalakottoor.github.io/PyOR/ Github: github.com/VThalakottoo... DOI: doi.org/10.5281/zeno... #NMR #NMRchat

I am excited to announce the first major release of PyOR (Python On Resonance)! PyOR is now modular: github.com/VThalakottoo... Download & cite: doi.org/10.5281/zeno... Here is a powder-averaged spectrum (CSA) simulated using PyOR: github.com/VThalakottoo... #NMR #NMRchat

PyOR is making small steps to do solid-state NMR. Look at this example about dipolar Hamiltonian and interaction tensor, Euler and Wigner rotation, and Wigner matrix. If you find something is wrong write to me. #NMR #NMRchat github.com/VThalakottoo...

It was worth building a 285 MHz resonator to spin the protons at 1.2 K for an extended period. NMR Maser from frozen water via DNP. #NMR #NMRchat

I have attended all summer schools (2020, 2023 to 2025) at Schloss Windischleuba (a beautiful castle) in Germany, organized by Jörg Matysik (Uni. of Leipzig). These schools have been my only classroom experience in learning NMR. Feel free to explore them yourself. #NMR #NMRchat

Here is an equation I derived for the vibration effect in NMR spectra. It is very similar to EOM (electro-optic modulator) in optics #NMR #NMRchat

Here are the presentation slides about PyOR Magnetic Resonance and PyOR Quantum from the talk I gave in the ENS RMN group meeting. It is a short introduction to the "new" PyOR. github.com/VThalakottoo... #NMR #NMRchat

I have added two functions, StateZeeman and States (if any coupled pair is present) to PyOR Quantum. Here is a tutorial for a 3-spin system in which any pairs are coupled. (Like PyOR Mag Res, PyoR Quantum supports an arbitrary spin system). #NMR #NMRchat github.com/VThalakottoo...

PyOR is divided into two (Like an "Amoeba"), PyOR Magnetic Resonance (PyOR original) and PyOR Quantum (for physics audience, still in development). Here is an example of a spin half system (Schrödinger Eq. and Liouville-von Neumann equation. #NMR #NMRchat github.com/VThalakottoo...

I was thinking of using the Bruker AU program to communicate with a wide range of instruments during my PhD days onwards. Today I established communication with an oscilloscope via "visa", a small move but may (will) be helpful for many NMR instrumentation people #NMR #NMRchat

I have uploaded a new version of PyOR (Python On Resonance) which is more user-friendly with more functionalities. I will upload more examples in the coming days. Looking forward to your feedback. github.com/VThalakottoo... #NMR #NMRchat

Recently, our team visited local government schools at Davangere and Shimoga, in India, and contributed ‘books and green boards’ to support the schools’ mission to provide quality education. Let's work together to spread the joy of learning! #CSR #Bruker #WeDiscoverTogether

PyOR (version: Jeener) can now take the Bruker shaped pulse file for simulations. It is also possible to include the effects of relaxation and radiation damping during the pulse. Example: Gaussian pulse (Gaus1.1000) Next goal: ssNMR and EPR github.com/VThalakottoo... #NMR #NMRchat
