Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

Transmission Raman Spectroscopy (TRS) for Accurate Authentication of API in Coated Hydroxychloroquine (HCQ) Tablets

Journal of Raman Spectroscopy, EarlyView.
We report the development and use of a transmission Raman spectroscopy (TRS) system for a more accurate but nonintrusive way of authentication of API in coated HCQ tablets which otherwise is not possible using the backscattered (BS) configuration of Raman spectroscopy. The coating interference is found to be almost zero in case of the TRS and a greater

Influence of different drying techniques on the quality and physicochemical properties of Ghana‐sourced turmeric (Curcuma longa L.) samples

JSFA reports, EarlyView.
Abstract Background This study evaluated the influence of four drying techniques—freeze drying (FZD), microwave drying (MCD), oven drying (OVD), and sun drying (SUD)—on the bioactive, nutritional, and physical properties of turmeric. Using standard analytical procedures, the samples were examined for antioxidant activity (DPPH and ABTS assays), total ...

Development of mango‐flavored soy‐based yogurt: Assessment of physicochemical properties and quality attributes

JSFA reports, EarlyView.
Abstract Background Yogurt is a widely consumed fermented dairy product valued for its nutritional quality, functional benefits, and formulation flexibility. Rising consumer interest in healthier and diversified foods has increased attention toward composite plant–dairy yogurts enriched with fruits and legumes.

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Three‐Dimensional Optical Characterization of Magnetostrictive Deformation in Magnomechanical Systems

Laser &Photonics Reviews, EarlyView.
An optical approach is proposed for real‐time and high‐precision detection of the magnetostrictive deformation of an yttrium‐iron‐garnet sphere in three dimensions, based on the deformation induced spatial high‐order modes of the scattered field, postselection, and balanced homodyne detection.
