Time-Current Characteristics for Bacterial Cellulose Membrane Systems with NaCl Solutions

Raw data from measurements and calculations of membrane currents under different NaCl solution configurations. The dataset, authored by Sławomir Grzegorczyn and last updated in May 2026, includes time-series data showing stable boundary layers in one configuration and current pulsations from hydrodynamic instabilities in another. Fast Fourier Transform (FFT) and Short Time Fourier Transform (STFT) analyses were applied to signals in the frequency range from 0.05 to 1 min⁻¹.

Use Cases

• Modeling hydrodynamic instabilities based on observed current pulsations over time.
• Analyzing the relationship between initial concentration quotient (C_h/C_l) and signal power using FFT results.
• Investigating the temporal evolution of instabilities using Short Time Fourier Transform (STFT) on current difference signals.
• Comparing steady-state membrane currents after 24 hours for different solution configurations.

Strengths

• Includes raw measurement and calculation data in a 990.0 KB XLSX file.
• Analysis covers specific frequency ranges (0.05 to 1 min⁻¹) and initial concentration quotients up to >2500.
• Data is licensed under CC-BY-4.0 for open reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
