Abstract Background and Aims Acute kidney injury (AKI) is a frequent complication in the intensive care unit (ICU). About 15% of critically ill patients with AKI require renal replacement therapy, commonly in the form of continuous renal replacement therapy (CRRT). This project aimed to develop a data pipeline to feed scalable smart dashboards of patient- and CRRT-relevant data to monitor key performance CRRT indicators and patient outcomes. Method We utilized EHR and CRRT device data from UAB from 1/2022 to 2/2024. Extracted CRRT device data (n = 42 devices). Loaded data from CRRT cards to a secure storage location for data processing. Created an ETL (extract, process, and load) data process in a virtual server environment using Python code to clean and normalize the data. Connected the Python data pipeline to feed the visualization layer via the Tableau cloud server and refresh automatically. Designed specific interactive dashboards with Tableau that exhibit key performance. CRRT indicators that are sustainably trackable on a weekly or monthly basis. Results We developed smart dashboards and AI-powered data analytics to support providers in exploring data for multiple use cases including quality assurance, process or clinical outcome predictions and CRRT data to augment support clinical decision-making. Conclusion The development of digital health solutions that integrate multimodal data from EHR and CRRT devices is feasible. While this is a key milestone to enable AI-powered CRRT delivery, the impact of these digital health solutions on processes and clinical outcomes needs to be tested with contemporary implementation science tools.

Thin film solar cells have emerged in recent years, in particular, those made of amorphous silicon or CIGS (copper indium gallium sellenide). By tendon of boron doped amorphous diamond with phosphorus doped amorphous silicon, the conversion efficiency may rival that of crystalline silicon. On the other hand, the CdS top layer for CIGS is not only poisonous, but also UV degradable. Amorphous diamond coating with N doping can replace CdS to boost CIGS's efficiency also. Nanodiamond may be sputtered from diamond grit or diamond film as target. The PVD formed nanodiamond layer can be located at the interface between P and N types. In this case, the quantum well effect can allow the production of multiple electrons per incident photon. In addition, the output voltage may be increased due to the wide band gap of nanodiamond.

Graphene is the ideal material for many dream applications, such as single electron transistors, field emission sources, light through electrodes, flexible solar cells, wall paper displays, UV light emitting diodes, atomic gas sensors, DNA or antigen wafers, terra hertz surface acoustic wave (SAW) generators and filters...etc. However, a practical method to fabricate meter-sized graphene is still beyond imagination. In this research, we reported a simple technology to harvest large area graphite films by using molten alloy as the catalyst. Each film contains hundreds or thousands layers of graphene. Some stacks of graphene revealed silk-like tenderness with transparent folding lines. This liquid phase epitaxy (LPE) process appears scalable for making graphene layers measured in meter size. This paper also presented many intriguing aspects related to the growth of large graphene.

For the first time working MEMS resonators have been produced using low-temperature deposited (550/spl deg/ C) Ultrananocrystalline/spl trade/ Diamond (UNCD/spl trade/) films. Using a lumped-element model to fit experimental data, UNCD materials properties such as a Young's modulus of 710 GPa and an acoustic velocity of 14,243 m/s have been deduced. This is the highest acoustic velocity measured to date for a diamond MEMS structural layer deposited at low temperatures. A 10 MHz resonator shows a DC-tunability of the resonance frequency of 15% between 15 and 25 V and the breakdown voltage behavior shows electrostatic breakdown rather than electro-mechanical pull-down for higher frequency devices. Good resonant frequency reproducibility is observed when cycling the resonators over bias voltages from 15 to 25 V and over RF power levels of -10 to 10 dBm.
