Biotechnology Journal, Volume 18, Issue 1, January 2023., 2023 Graphical Abstract and Lay Summary The heterogenous production conditions in large‐scale bioreactors cause scale‐up problems, such as reduced biomass or product yield, to occur during bioprocesses. In this study, we designed a two‐compartment scale‐down reactor and used it to simulate large‐scale heterogenous production conditions, allowing us to ...

Infrared thermal imaging for melt pool analysis in SLM: a feasibility investigation
Virtual and Physical Prototyping, 2018 Melt pool dimension can help to relate process parameters and build part quality in selective laser melting (SLM) process. In this study, a near-infrared thermal imager (about 670 nm spectral range) was employed to collect powder layer thermal signal in ...

Advanced Functional Materials, EarlyView.In this article, a water‐evaporation driven energy harvester is devised that works even in the absence of sunlight. This is achieved by combining PVA hydrogel with thermoelectrics (TEG) to directly capture energy from water evaporation. Under mild conditions (RH 40%, T of 26 °C, and 2.8 m s−1 wind), 1.71 mW (1.02 W m−2) power can be generated, >3 fold ...

Biotechnology Journal, Volume 18, Issue 1, January 2023., 2023 Graphical Abstract and Lay Summary The transition to continuous biomanufacturing is hampered by the lack of suitable process analytical tools able to collect real‐time information on the process and elicit a response. A possible solution is miniaturized sensors to be placed after each unit operation.

Demystifying the Data Need of ML-surrogates for CFD Simulations [PDF]
arXiv, 2022 Computational fluid dynamics (CFD) simulations, a critical tool in various engineering applications, often require significant time and compute power to predict flow properties. The high computational cost associated with CFD simulations significantly restricts the scope of design space exploration and limits their use in planning and operational ...

Advanced Healthcare Materials, EarlyView.Volumetric muscle loss (VML) due to trauma or surgery, often leads to physical impairments. Traditional treatments rely on autologous flaps, limited by muscle availability often leading to donor site morbidity. This study presents multimodal bioprinting as an innovative approach for fabricating vascularized muscle flaps with 3D‐printed macrovessels ...

Heat Transfer in a Loop Heat Pipe Using Fe2NiO4-H2O Nanofluid
MATEC Web of Conferences, 2017 Nanofluids are stable suspensions of nano fibers and particles in fluids. Recent investigations show that thermal behavior of these fluids, such as improved thermal conductivity and convection coefficients are superior to those of pure fluid or fluid ...

Simulation Model for Digital Twins of Pneumatic Vacuum Ejectors
Chemical Engineering &Technology, Volume 46, Issue 1, Page 71-79, January 2023., 2023 A novel concept for modeling and simulating the fluidic behavior of pneumatic vacuum ejectors as key components of vacuum handling systems is proposed. To increase the simulation accuracy, the concept can access instance‐specific data instead of object‐specific data.
