Investigation of Aeration Rate on Uranium Bioleaching in Internal Airlift Bioreactor [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2012
Uranium is leached from the uranium ore of the second anomaly of Saghand by the Acidithiobacillus ferrooxidans bacteria in an internal airlift bio-reactor. This study has been made to find the effect of aeration rate as well as its optimal value.

Dynamics and Control of Oscillatory Bioreactors [PDF]

open access: yesarXiv, 2023
Bioreactors are widely used in many industries to generate a range of products using various host cells e.g., yeast, insect, and mammalian cells. Depending on the process, product, and host cell, some bioreactors exhibit sustained periodic behavior in key process variables such as metabolite concentrations, biomass, and product titer.

Sonochemical Functionalization of Glass

open access: yesAdvanced Functional Materials, EarlyView.
A new method for functionalizing glass using ultrasonication of aryl diazonium salts. Aryl radicals generated by ultrasounds react with glass, forming a stable, covalently bonded organic film. The functionalized glass adheres microorganisms such as microalgae, fungi, and bacteria, suggesting potential applications in enzyme production, filtration ...

CFD modelling of two-phase stirred bioreaction systems by segregated solution of the Euler–Euler model [PDF]

open access: yes, 2013
An advanced study of a bioreactor system involving a Navier–Stokes based model has been accomplished. The model allows a more realistic impeller induced flow image to be combined with the Monod bioreaction kinetics reported previously. The time-course of

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

open access: yesAdvanced Functional Materials, EarlyView.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Investigating biomechanical determinants of endothelial permeability in a modified hollow fibre bioreactor [PDF]

open access: yesarXiv, 2023
Effects of mechanical stress on the permeability of vascular endothelium are important to normal physiology and may be critical in the development of atherosclerosis, where they can account for the patchy arterial distribution of the disease. Such properties are frequently investigated in vitro.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Field models and numerical dosimetry inside an extremely-low-frequency electromagnetic bioreactor: the theoretical link between the electromagnetically induced mechanical forces and the biological mechanisms of the cell tensegrity [PDF]

open access: yesSpringerPlus 2014;3:473, 2019
We have implemented field models and performed a detailed numerical dosimetry inside our extremely-low-frequency electromagnetic bioreactor which has been successfully used in $\textit{in vitro}$ Biotechnology and Tissue Engineering researches. The numerical dosimetry permitted to map the magnetic induction field (maximum module equal to about 3.3 mT ...
