Article Abstract
Supercontinuum radiation has found numerous applications in diverse fields encompassing spectroscopy, pulse compression, and tunable laser sources. Anomalous enhanced stimulated Raman scattering (SRS) of cyclohexane-benzene mixtures was obtained in this study. SRS of the pure solvent, the multi-order Stokes of the strongest fundamental vibration modes, and energy transfer in intra-molecular modes were observed. SRS of the mixture revealed that the cross-pumping effect was generated between the C-H stretching (v) mode of cyclohexane and the C=C ring skeleton (v) mode of benzene, thereby producing the intermolecular secondary stimulated Raman emission and the appearance of two super-broadband radiations at 664.36-673.9 nm and 704.62-729.22 nm. The results suggest that the energy transfer of intermolecular vibrational modes, where the strongest vibrational mode excites other vibrational modes, is a simple approach for generating supercontinuum coherent radiation.

Biofilms are microbial communities that adhere to surfaces and each other, encapsulated in a protective extracellular matrix. These structures enhance resistance to antimicrobials, contributing to 65-80% of human infections. The transition from free-living cells to structured biofilms involves a myriad of molecular and structural adaptations.

Natural protein-derived peptides are gaining attention for their potential in promoting health, particularly in nutraceutical formulations. In this study, calcium-binding peptides from lotus seed were produced and characterized using UV, FT-IR, Raman, and EDS, and SEM. The calcium-peptide (LSPIH-Ca) complex was subjected to its osteogenic effect in murine bone marrow-derived mesenchymal stem cells (D1 MSCs).

Background: Stimulated Raman histology (SRH) is a novel microscopic technique allowing real-time, label free, high-resolution microscopic images of unprocessed, unsectioned tissue. Tissue samples are imaged in the operating room using a mobile SRH microscope. Due to SRH's pseudocoloring, the images appear like conventional H&E staining.

Raman spectroscopy is a powerful method for analyzing chemical compositions across diverse samples. Spontaneous Raman scattering (spRS) provides complete Raman spectra but typically yields low signal levels, requiring long signal integration times. In contrast, stimulated Raman scattering (SRS) produces much stronger signals, allowing for rapid spectral acquisition, and has been widely used to accelerate chemical imaging.

Recently developed Chimeric Antigen Receptor T (CAR-T) cell therapy has shown potent clinical efficacy against hematological malignancies. However, solid tumors, including ovarian cancer, possess several mechanisms that hinder T cell activity, and metabolic alteration of cancer cells has been shown to contribute to resistance to immune cell attack against solid tumors.
