Scaling challenges in microalgae cultivation: environmental effects on biomass productivity

Microalgae are photosynthetic microorganisms that can convert CO₂ into valuable biomass for applications such as nutrition, biofuel production, and wastewater treatment. However, scaling from laboratory to industrial volumes remains empirical and…

Scaling microalgae cultivation: from environmental effects on cell growth to a predictive hybrid modeling framework

Microalgae are photosynthetic microorganisms that convert CO₂ into valuable biomass for nutrition, biofuel production, and wastewater treatment. However, scaling from laboratory to industrial volumes remains largely empirical, as cultivation…

Field-localization-driven gas discrimination in porous silicon defect cavities

Porous-silicon photonic crystal cavities are widely used as refractive-index-based optical sensing platforms, but their response is often interpreted through a single observable, typically the resonance wavelength shift. This single-feature readout…

Adsorption-driven Graphene Oxide SPR Biointerfaces: Coupled Thermodynamic, Kinetic, and Optical Modeling with Effective-layer Validation

This work presents a theoretical modeling framework for adsorption-driven graphene oxide (GO)-functionalized surface plasmon resonance (SPR) biointerfaces. Rather than describing a specific capture-probe biosensor, the model focuses on the effective…

Sensitivity collapse in whispering gallery mode refractometric sensing of porous microspheres: A finite-window mode-misassignment mechanism

Fluorescence-based whispering-gallery-mode (WGM) sensors routinely report refractometric sensitivities far below the intrinsic limit Sintrinsic = λ/neff, yet the origin of this discrepancy has not been rigorously quantified. Here we show that a…

Trade-off and Performance of Optoplasmonic Mesoporous WGM Sensors

Optoplasmonic whispering-gallery-mode (WGM) sensors are often presented as a direct route to enhanced detection limits because localized surface plasmon resonances can create extreme near-field intensities. However, for passive WGM refractometric…

Fourier-Transform-Based Metrology for Whispering Gallery Mode Spectra in Soft Photonic Microcavities

We present a Fourier-transform (FT)-based framework for quantitative analysis of whispering gallery mode (WGM) spectra in soft photonic microcavities. By treating the WGM spectrum as a quasi-periodic signal, the method enables robust extraction of…

Simulation of Rydberg Ionization in Atomic Beams for FIB Optimization

This study explores the excitation and ionization of an atomic beam as a pathway to optimize focused ion beams (FIBs) for high-precision applications. Leveraging the unique advantages of Rydberg excitation followed by field ionization-specifically…
