Raman Spectroscopy–Based Glucose Feed Control Automates Malic Acid Fermentation

Biotechnology and Bioengineering, Volume 123, Issue 6, Page 1721-1732, June 2026.
Raman spectroscopy enables automated, closed‐loop glucose feeding for malic acid production with Ustilago trichophora. Online PLS regression of glucose and malic acid provides input for PID control to maintain 20 g/L glucose. The feed is dynamically adjusted and stopped in response to metabolic demand and product inhibition, demonstrating practical ...

Using Principal Components Analysis to Visualize Motion and Mitigate Artifacts in Dynamic Optical Coherence Tomography

Journal of Biophotonics, Volume 19, Issue 6, June 2026.
We demonstrate that Principal Component Analysis (PCA) can be used in dynamic OCT to substantially reduce artifacts from strong specular reflections, isolate movement within the sample, and create thin, histology‐like images, thereby avoiding the need for complex, time‐consuming techniques used in clinical histopathology.

Background Instability of Quintessence Model in Light of Entropy and Distance Conjecture

Fortschritte der Physik, Volume 74, Issue 6, June 2026.
ABSTRACT We apply the covariant entropy bound argument supporting the de Sitter swampland conjecture to the quintessence model, to find out the condition for the background to be unstable. More concretely, the background is unstable when the matter entropy given by the species number of the effective field theory increases more rapidly than the ...

Reconfigurable Nanogap SERS for Multiscale Molecular Sensing on Curved Surfaces

Small, Volume 22, Issue 35, 23 June 2026.
Reconfigurable Au‐coated SMP nanocomposites enable adaptive SERS through reversible tuning of Au─Au nanogaps. Embedded AgNPs serve as photothermal triggers and reinforcements. Wide gaps facilitate macromolecule detection, while narrowed gaps enhance small‐molecule signals for reliable multiscale sensing on curved surfaces.

Precise 3D Tracking of Highly Non‐Planar Eukaryotic Flagellar Beating Patterns Using Digital Holographic Microscopy

Small Methods, Volume 10, Issue 12, 23 June 2026.
The 3D beating dynamics of eukaryotic flagella drive motility, sensory functions, and resource acquisition, yet highly non‐planar beating patterns remain poorly characterized. Based on Digital Holographic Microscopy, holoV3C enables label‐free 3D reconstruction of such complex dynamics with 53 nm axial resolution, demonstrated on mouse sperm and ...
