IntroductionThe essential oil of pennyroyal has a number of bioactive properties, including antiviral, antifungal, and anti-inflammatory effects. Accurate, rapid, and non-destructive assessment of its quality is therefore a major challenge for the pharmaceutical industry. Conventional methods, such as gas chromatography, although effective, are time-consuming, destructive, and require the use of …

In the realm of scientific exploration, a fascinating synergy emerges when cutting-edge technology meets traditional methodologies. Imagine this: machine learning stepping into the world of spectroscopy analysis, sparking waves of innovation within laboratory walls. This partnership reveals a spectrum of possibilities, where data-driven precision intertwines with the intricate dance of spectral a…

Using a cascaded architecture of gas-filled hollow-core fiber (HCF), bare lithium niobate (LN) crystal plate, and a specially designed chirped periodically poled lithium niobate crystal (CPPLN), researchers have demonstrated four-octave-spanning intense ultraviolet-visible-infrared (UV-Vis-IR) full-spectrum laser source with the energy of 0.54 mJ per pulse. The HCF-LN system can produce an intens…

Fast. Compact. Easy to use. These are just a few ways to describe our suite of spectrometers. These innovative instruments can be used in both... The post Spotlight on Our Go Direct® Spectrometers appeared first on Vernier .

Infrared (IR) vibrational scattering scanning near-field optical microscopy (s-SNOM) has advanced to become a powerful nano-imaging and -spectroscopy technique to probe molecular and lattice vibrations, low-energy electronic excitations and correlations, and related collective surface plasmon, phonon, or other polaritonic resonances. s-SNOM enables the study of complex heterogeneous materials wit…
