Space Pump: Repairable 3D‐Printed Bioinspired Pneumatic Peristaltic Pump for Fluid and Regolith Transport in Space

open access: yesAdvanced Intelligent Systems, EarlyView.
The space pump transports lunar regolith under vacuum condition. A fully 3D‐printed biomimetic peristaltic pump demonstrates reliable transport of liquids and solids using pneumatic ring actuators and flexible fused filament fabrication. The system operates under atmospheric and vacuum conditions, achieves high flow rates, and enables self‐priming ...

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.

Numerical investigation of pressure-equalizing groove configuration effects on gas bearing performance

open access: yesFrontiers in Mechanical Engineering
High-speed rotating machinery has extremely high requirements for the performance and reliability of aerostatic bearings, and the design of pressure-equalizing groove structure is a key factor determining the performance of aerostatic bearings under high-

Challenges in meeting the mass transfer demands of high‐density perfusion cultures in single‐use bioreactors

open access: yesBiotechnology Progress, EarlyView.
Abstract Increasing protein therapeutics production by adopting intensified perfusion cultures places high demand on the mass transfer capabilities of single‐use bioreactors (SUB). Here, we compare these capabilities for four SUB designs against worst‐case O2 transfer requirements for supporting Chinese hamster ovary (CHO) perfusion cultures. Impact of

Amino Acid and Biogenic Amine Profiles in Sausages Reformulated With Processed, Fermented Oyster Mushrooms

open access: yesChemFoodChem, EarlyView.
This research showed that sausage reformulation preserves high essential amino acid and branched‐chain amino acid content, as well as increasing free amino acids (FAA) related to umami flavor and health‐promoting components such as GABA in the products.

Occurrence of severe slugging in oil production lines and mitigation methods: A numerical simulation approach using ALFAsim®

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Severe slugging represents a major challenge in offshore production systems, potentially compromising operational stability and the integrity of installations. Although established simulators such as OLGA® are widely used for its analysis, there is a gap in the literature regarding the application of the one‐dimensional simulator ALFAsim® for ...

Algebraic model for predicting the hydrodynamics of cocurrent three‐phase fluidized columns

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study presents a novel simplified set of momentum equations to predict the overall hydrodynamics of a cocurrent gas–liquid–solid slurry bed, including phase fractions and pressure drop. The mentioned momentum closures are derived from an idealization of the upward flows within the bed of solid particles, obtained by extending an approach ...

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

open access: yesDeep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Hydrostatic liquid-bearing for precision gyro [PDF]

open access: yes, 1971
Unit with 2W power increase and slightly larger overall dimensions performs as well as or better than its gas-bearing counterpart. Liquid-bearings are built by reworking serviceable gas-bearing components /sleeves, endplates, and cylinders/.
