Enhancing cell potency is therefore critical, especially for autologous applications. Biophysical treatment e.g. extracorporeal shockwave therapy (ESWT) has emerged as a promising tool to enhance the regenerative potential of cells and has been applied in clinical practice for the treatment of several diseases. We developed a novel, low-cost, small and adaptable multi-mode pulse generating system (PGS) that enables direct treatment of cells in 3D-printed microfluidic devices. Adipose-derived cell treatment by our novel PGS showed first promising results, including significantly increased cellular adenosine triphosphate (ATP) release and proliferation. Enhanced cell functionality could be observed through a significantly increased adipogenic differentiation potential and a trend towards osteogenic and chondrogenic lineages. This novel approach offers unique characteristics achieved by its small dimensions and light weight that come along with increased flexibility and high integrability in existing systems and could therefore overcome limitations faced by conventional biophysical methods. It enables the combination of the process of cell treatment and live monitoring of cells and could therefore emerge in the field of bioprinting, in lab-on-a-chip applications as well as future clinical applications in cell-based therapies for many different therapeutic fields.</div></div>","PeriodicalId":72251,"journal":{"name":"Applications in engineering science","volume":"22 ","pages":"Article 100216"},"PeriodicalIF":2.2,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143735092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Articulated robot arms are commonly used in WAAM to produce complex geometric shapes. However, they mostly rely on proprietary robot and weld control software that limits process tuning and customization, incorporation of third-party sensors, implementation on robots and weld controllers from multiple vendors, and customizable user programming. This paper presents a general open-source software architecture for WAAM that addresses these limitations. The foundation of this architecture is Robot Raconteur, an open-source control and communication framework that serves as the middleware for integrating robots and sensors from different vendors. Based on this architecture, we developed an end-to-end robotic WAAM implementation that takes a CAD file to a printed WAAM part and evaluates the accuracy of the result. The major components in the architecture include part slicing, robot motion planning, part metrology, in-process sensing, and process tuning. The current implementation is based on Motoman robots and Fronius weld controller, but the approach is adaptable to other industrial robots and weld controllers. The capability of the WAAM system is demonstrated through the printing of parts with various geometries and acquisition of in-process sensor data for real-time motion adjustment.</div></div>","PeriodicalId":72251,"journal":{"name":"Applications in engineering science","volume":"22 ","pages":"Article 100204"},"PeriodicalIF":2.2,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Mach number as well as the Reynolds and Prandtl numbers have an influence on the recovery factor. These integral results will be verified by measuring the tangential temperature distribution. For this purpose, a special sensor carrier was developed and moved quickly through the ambient air at different angular positions so that the tangential temperature distribution could be determined. In accordance with the theory, the highest temperature is at the accumulation point with the total temperature and the local recovery factor is 1. The temperature drops continuously to an angle of about 80°. In the wake of the cylinder there is a roughly constant temperature level.

Essential to these designs are understanding how cells respond to mechanical compression and the thresholds for initiating catastrophic failure. This study investigates how the state of charge (SOC) affects the compressive mechanical behaviour and the occurrence of internal short circuits (ISC) in lithium-ion pouch cells. NMC811 lithium-ion pouch cells were subjected to uniaxial compression tests at different SOCs, namely deep discharge, 0 %, 50 %, and 100 %. The results showed that the SOC has a minor effect on macroscopic compression behaviour and the occurrence of ISC. Engineering stress at ISC increased linearly with the SOC due to slight stiffening at higher SOC levels, while engineering strain at ISC remained constant. These findings suggest that deep-discharged cells can be used for safer mechanical testing, as their mechanical response is effectively equivalent to that of charged cells, but poses a lower safety risk. Furthermore, the results of this study align with prior research regarding the influence of SOC on the mechanical response of pouch cells. Such response is deemed to be influenced by compressive internal stresses, generated by the constrained SOC-related swelling of the jellyroll.</div></div>","PeriodicalId":72251,"journal":{"name":"Applications in engineering science","volume":"21 ","pages":"Article 100211"},"PeriodicalIF":2.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments were conducted to study the effects of volumetric energy density (VED) on the integrity and properties of the resulting surface. Instruments including microscopy, interferometry, spectroscopy, and hardness measurements were used to characterize the coated surfaces. The results show that coating defect such as cracks and spatters can be reduced with increased VED. The coating hardness, in general, decreases with increased VED. As stainless steel and H13 tool steel were used as the substrate, the study also identified that the thermal conductivity of the substrate material play a significant role in crack formation. It is also found that surface preparation, through machining, can affect the retention of the powder and lead to a higher surface hardness. Overall the hardness increase ranged from 200 % to 300 %.
