"Recently, a novel air-laser-based standoff Raman spectrometer with high temporal and frequency resolutions has been constructed by Yao Fu et al, with which one can remotely probe chemical species in real time with high temporal resolution while monitoring the populations in their respective rovibronic levels in the frequency domain with sufficiently high spectral resolution".

Our paper on immiscible #polyolefin blends is out! Here we check out the effects of polyethylene-polypropylene blend composition on #crystallization and melting - morphology plays a huge role in the rheological properties during crystallization as well as the #crystallization temperature of the blend components: https://pubs.acs.org/doi/full/10.1021/acs.macromol.2c01691 #rheology #raman #dsc

Though Sir Venkata Raman was the first non-white person to get a Nobel prize in STEM, not many Indians were conferred the prestigious prize in the later years. :india:

This does not, however, mean that Indians did not have any remarkable contribution to modern science after #Raman. In this thread, in the coming days, I will be posting about the research and biographies of some Indians who, despite having made breakthroughs in science, were never awarded the Swedish prize.

On 28 February 1928, Sir Chandrasekhara Venkata Raman discovered the Raman effect. The Raman effect is the change in the wavelength of light that occurs when a light beam is deflected by molecules. https://t.co/jtVLH0n1Rc

28th FFebruary each year is celebrated as National Science Day in #India, marking #Raman's discovery of the #RamanEffect.
