  • Bands appear and vanish as the potential is swept — a movie, not a snapshot. Illustrative schematic; What is the electrode surface doing while it works?

    Operando Electrochemical Raman: Watching an Electrode Think
    Operando electrochemical Raman records Raman spectra inside a live electrochemical cell, potential by potential — a movie of the working electrode surface, not a before/after snapshot.
  • In GeS the Ag modes at 110, 236 and 269 cm⁻¹ appear along the armchair axis; B3g at 210 cm⁻¹ only across it. Illustrative schematic; Can one rotation identify an unknown layered crystal?

    Four Unknown Semiconductors, One Question a Single Spectrum Can’t Answer
    An ordinary spectrum tells you a material is there. Polarized Raman and µPL on RAMaker tell you what it is — proven across four unrelated layered semiconductors, one independent lab, seven months.
  • The silicon line at 520 cm⁻¹ is the internal reference; the dye bands are what grow. Illustrative schematic; What does the pyramid texture actually buy you?

    A SERS Chip You Can Make in 3 Minutes, at Room Temperature, Without a Vacuum Chamber
    Silver-on-silicon SERS substrates made in 3 minutes at room temperature, no vacuum gear — and exactly what a pyramid texture buys you in sensitivity.
  • Illustrative schematic: one nanowire array first destroys the pollutant under light, then reads what is left by SERS.

    One Nanowire Array, Two Jobs: Destroy the Pollutant, Then Detect It
    Two studies, one idea: semiconductor nanowire arrays that photocatalytically destroy a dye and, decorated with silver, detect it by SERS down to 10⁻⁹ M.
  • The platform is quantified on the R6G band at 1361 cm⁻¹, once the drop is pinned in place. Illustrative schematic; Why does a droplet that sits still measure better?

    Printing Tiny Hydrophobic Corrals So Droplets Sit Still for SERS
    An ionic-liquid electropolymerization route patterns hydrophobic wells on ITO and flexible film — droplet arrays for electrochemistry and SERS on the MRI.
  • Intensity says how bright; only the decay says why. Illustrative schematic; Two samples, equal brightness — are they the same?

    TCSPC Explained: What RAMaker’s Photon Counting Reveals
    One measurement, two unrelated problems solved — how time-correlated single-photon counting on RAMaker separates real physics from simple brightness.
  • The oxide is nearly Raman-silent, so any D and G must come from the buried layer. Illustrative schematic; Is the graphene still there under the oxide?

    Raman Confirms the Buried Graphene Layer That Makes IGZO Electronics Work
    Two studies used MRI Raman to verify the buried graphene interlayer that lowers resistivity and toughens IGZO thin films for flexible electronics.
