Temperature‐Dependent Investigation of the S‐Branch Raman Linewidth in CO2 via Time‐Resolved Rotational CARS

Journal of Raman Spectroscopy, Volume 57, Issue 4, Page 725-734, April 2026.
We studied the temporal evolution of the rotational coherent anti‐Stokes Raman scattering (RCARS) signal of CO2 to determine the S‐branch Raman linewidth, which is an essential parameter for accurate spectral modeling in RCARS gas‐phase diagnostics. We found a non‐monotonic J‐dependence of the S‐branch Raman linewidth not accounted for in previously ...

Resolving fine spectral features in lattice vibrational modes using femtosecond coherent spectroscopy

AIP Advances, 2016
We show resolution of fine spectral features within several Raman active vibrational modes in potassium titanyl phosphate (KTP) crystal. Measurements are performed using a femtosecond time-domain coherent anti-Stokes Raman scattering spectroscopy ...

The contribution of vibrational spectroscopy and data analytics towards the achievement of the global sustainability goals

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3239-3246, April 2026.
Abstract The United Nations Sustainable Development Goals (UN SDGs) were defined to improve the quality of life of the global population particularly regarding social and economic aspects, with a major focus on environmental sustainability. The incorporation of digital technologies into the agri‐food sector has become a key enabler in increasing the ...

Methane-air flame thermometry using planar lase-induced fluorescence (PLIF)

MATEC Web of Conferences, 2018
Temperature measurements were performed in a central cross-section of a partially premixed atmospheric methane-air flame of a laboratory burner using two-line planar laser-induced fluorescence (PLIF) of OH radicals and coherent anti-Stokes Raman ...

Noise auto-correlation spectroscopy with coherent Raman scattering

, 2007
Ultrafast lasers have become one of the most powerful tools in coherent nonlinear optical spectroscopy. Short pulses enable direct observation of fast molecular dynamics, whereas broad spectral bandwidth offers ways of controlling nonlinear optical ...

In vitro, cellular and in vivo studies of amyloid oligomers structure and toxicity: Challenges and advances

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Oligomeric assemblies of amyloidogenic proteins, such as Aβ, tau, α‐synuclein, amylin, transthyretin, and TDP‐43, are increasingly recognized as key drivers of cellular dysfunction across a range of neurodegenerative and systemic disorders.

Manifestation of exciton Bose condensation in induced two-phonon emission and Raman scattering

, 1998
The unusual two-photon emission by Bose-condensed excitons caused by simultaneous recombination of two excitons with opposite momenta leaving the occupation numbers of excitonic states with momenta $p nonequal to 0$ unchanged (below coherent two-exciton ...

Optical Heterodyne-Detected Raman-Induced Kerr Effect (OHD-RIKE) Microscopy [PDF]

, 2014
Label-free microscopy based on Raman scattering has been increasingly used in biomedical research to image samples that cannot be labeled or stained. Stimulated Raman scattering (SRS) microscopy allows signal amplification of the weak Raman signal for ...

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.
