A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

Low‐Field MRI as a Multiparametric Tool for Large Engineered Tissue Characterization

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Advances in 3D bioprinting have enabled the fabrication of large and complex engineered tissues, but their increasing size demands non‐invasive tools for monitoring structure, maturation, and perfusion. Magnetic Resonance Imaging (MRI) offers unique multiparametric capabilities, yet high‐field systems remain costly and inaccessible for most ...

Investigation of Severe Turbulence Over China During 2018–2025 From In Situ EDR Data

open access: yesMeteorological Applications
The nation‐scale airborne turbulence features remain unclear in China. We investigated the characteristics of turbulence for the period 2018–2025 over China based on in situ eddy dissipation rate (EDR) observations of turbulence from Xiamen Airlines, in ...

Scalable Separation and Purification of M13‐Bacteriophage‐Derived Particles Containing Artificial Single‐Stranded DNA Produced by Escherichia coli

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Single‐stranded DNA (ssDNA) solutions are promising innovations shaping the future of genetic research and medical therapies. In principle, biotechnological mass production of ssDNA can be achieved using Escherichia coli in a high‐cell density fed‐batch process by secreting phagemid particles derived from the filamentous M13 bacteriophages ...

A General Workflow for Tangential Flow Filtration Perfusion Scale‐Up

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Tangential flow filtration (TFF) perfusion using hollow‐fiber modules offers substantial advantages over other mammalian cell retention technologies. Recently, increased awareness of Starling flow has helped to enhance filtration performance to similar, or even higher levels compared to alternative technologies.

Experimental Investigation of Turbulence Specifications of Turbidity Currents

open access: yesJournal of Applied Fluid Mechanics, 2010
The present study investigates the turbulence characteristic of turbidity current experimentally. The three-dimensional Acoustic-Doppler Velocimeter (ADV) was used to measure the instantaneous velocity and characteristics of the turbulent flow.

Green Ambiguity Shapes Sustainable Investing

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Green Exchange‐Traded Funds (ETFs) have experienced strong growth in recent years, reflecting increasing investor attention toward sustainability. However, these funds rely on a wide range of environmental metrics that are often weakly aligned, raising concerns about the meaning of greenness in sustainable investing.
