Unveiling chemical composition of peppermint oil and its bioactivities compared with (R)‐(+)‐limonene: antimicrobial, antibiofilm, and insecticidal perspectives

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Peppermint (Mentha piperita L.) essential oil (MPEO) is recognized for its broad‐spectrum antimicrobial properties and potential applications in food preservation. This study aimed to determine whether the bioactivity of MPEO is attributable to (R)‐(+)‐limonene or whether the complete essential oil provides higher efficacy due to ...

Introducing a ramped pyrolysis/oxidation‐14CO2 analysis system operated with mobile molecular sieve traps

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract A novel instrument for the thermal degradation of sedimentary organic matter was set up at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with the aim of enabling Ramped Pyrolysis/Oxidation‐14C analysis as direct CO2 gas measurement.

Visible Octave Frequency Combs in Silicon Nitride Nanophotonic Waveguides Driven by Ti:Sapphire Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

Broadband Chromatic Dispersion of Thermo‐Refractive Coefficients and Its Impact in Silicon Nitride Nonlinear Photonics

open access: yesLaser &Photonics Reviews, EarlyView.
Chromatic dispersion of material thermo‐refractive coefficients is characterized across an octave in integrated Si3N4${\rm Si}_3{\rm N}_4$/SiO2${\rm SiO}_2$ platforms. A 7% variation is observed from telecom to visible wavelengths, while incorporating this dispersion into multiphysics modeling captures frequency‐dependent resonance shifts and improves ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).
