Development of Selective Plane Illumination Surface Enhanced Raman Scattering Spectral Microscopy for Improved Cellular Imaging

open access: yesJournal of Raman Spectroscopy, EarlyView.
Selective plane illumination (SPI) is combined with SERS spectral imaging to reduce background, improve image contrast, and enable improved spectroscopy from molecules on the surface of nanoparticles. This approach provides improved imaging and spectroscopy from nanoparticles in complex environments, such as biological cells.

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

open access: yesJournal 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 ...

Strain Imaging of GaAs by Stimulated Raman Scattering Microscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
Telecom‐wavelength stimulated Raman scattering (SRS) microscopy is developed for high‐throughput, nondestructive characterization of gallium arsenide (GaAs). By overcoming optical absorption limits of conventional Raman systems, this technique enables precise visualization of LO phonon frequency variations (< 0.2‐cm−1$$ {}^{-1} $$ precision).

Inter‐Theta‐Gram Spectroscopy: A General Super‐Spectral‐Resolution Scattering Method Demonstrated on Diamond

open access: yesJournal of Raman Spectroscopy, EarlyView.
Inter‐Theta‐Gram spectroscopy enables super‐spectral‐resolution Raman analysis by jointly reconstructing the excitation laser line and Raman peak during an etalon angle scan, yielding internally referenced Raman shifts. Demonstrated on lab‐grown versus natural diamond, it resolves 0.1–0.2 cm−1 Raman‐shift offsets that are invisible in conventional ...

Physical and organoleptic characteristics of Limmu coffee landraces, southwestern Ethiopia

open access: yesJSFA reports, EarlyView.
Abstract Background Coffee (Coffea arabica L.) is one of the world's most valuable agricultural commodities, with Ethiopia recognized for producing high‐quality Arabica coffee. Limmu landrace coffees are prized for their distinctive flavor profiles; however, systematic evaluation of their raw and cup quality traits remains limited.

Augmented Reality Integration Improves Ergonomics in Dynamic Navigation for Dental Implant Surgery

open access: yesJournal of the Society for Information Display, EarlyView.
This model‐based study demonstrates that integrating augmented reality (AR) to project X‐Guide navigation data directly onto the surgical field eliminates attention shifts between the patient and monitor, enhancing ergonomic efficiency. The AR system, which projects digital guidance directly into the surgeon’s line of sight, achieved high precision and
