Colonic drug delivery offers numerous pharmaceutical opportunities, including direct access to local therapeutic targets and drug bioavailability benefits arising from the colonic epithelium's reduced abundance of cytochrome P450 enzymes and particular efflux transporters. Current workflows for developing colonic drug delivery systems involve time-...

The heterogeneity, non-uniform nature, and ethical concerns in sourcing biological tissues pose several challenges to designing, calibrating, standardizing, and evaluating the performance of spectroscopy-based diagnostic methods. A synthetic phantom module that can resemble a multi-layered tissue structure while including multiple tissue biomarkers...

The present study reflects the synthesis of MgNb2O6 using hydrofluoric acid via a wet chemical approach, followed by characterizations involving XRD, electron microscopy, Raman spectroscopy, optical analyses, and impedance spectroscopy. The crystallite size of the synthesized material was determined to be 44 nm through XRD analysis. The lattice par...

Plant pathogens, including viruses, bacteria, and fungi, cause massive crop losses around the world. Abiotic stresses, such as drought, salinity and nutritional deficiencies are even more detrimental. Timely diagnostics of plant diseases and abiotic stresses can be used to provide site- and doze-specific treatment of plants. In addition to the dire...

We study the dependence of photo-spectral intensity on tri- and multilayers of SiO2/[SiGe [ dSiGe]/SiO2]N with repetitions N = 1 to 10 and thicknesses dSiGe=5–100 nm. Photocurrent analysis reveals a bimodal spectral feature. A comparison of the photocurrent analysis between tri- and multilayers shows that in the multilayer structures, the photo-spe...

Ilmenite (Fe2+TiO3) and geikielite (MgTiO3) are important terrestrial minerals relevant to the geology of the Earth, the Moon, Mars, and meteorite samples. Raman spectroscopy is a powerful technique that allows for mineral cation determination for the ilmenite–geikielite solid solution. We report on a suite of nine samples within the ilmenite–geiki...

We analyzed the effects of a hypo-osmotic environment on rat Schwann cells, a type of glial cell surrounding neurons, using ultra-broadband multiplex coherent anti-Stokes Raman scattering (CARS) microscopy. After hypo-osmotic treatment, we detected vacuole-like components in the cytoplasm using both bright-field and CARS spectroscopic imaging. An a...

The aim of this study is to determine changes in the near-surface layer of ZrO2 ceramics caused by irradiation with low-energy He2+ ions, as well as the associated formation of defects and structural deformations. During the experimental work conducted, it was established that the accumulation of deformation-structural distortions is of two stage n...

We investigated interlayer modes of few-layer HfX2 (X = S, Se) by using low-frequency micro-Raman spectroscopy with three excitation energies (1.96 eV, 2.33 eV, 2.54 eV) under vacuum condition (∼10−6Torr). We observed interlayer modes in HfSe2 when the 2.54 eV excitation energy was used. The low-frequency Raman spectra reveal a series of shear and ...
