A strategic approach to evaluating battery innovation investments.

Driven predominantly by public and private innovation, rechargeable batteries have, over a few decades, graduated from powering luxury consumer electronics to becoming one of the linchpins of the energy transition. Rapid adoption trends of batteries must accelerate to meet global net-zero targets for mobility and stationary storage, and will require making sound investments in battery innovation that deliver the most value. Because battery innovation is increasingly complex, multi-disciplinary, and subject to the coordination of stakeholders across academia, industry, government, and the broader public, building common and intuitive frameworks for understanding becomes critical to making progress.

P300 Modulates Endothelial Mechanotransduction of Fluid Shear Stress.

Purpose: P300 is a lysine acetyltransferase that plays a significant role in regulating transcription and the nuclear acetylome. While P300 has been shown to be required for the transcription of certain early flow responsive genes, relatively little is known about its role in the endothelial response to hemodynamic fluid stress. Here we sought to define the role of P300 in mechanotransduction of fluid shear stress in the vascular endothelium.

Stimulated Brillouin scattering flow cytometry.

We present the use of stimulated Brillouin scattering spectroscopy to achieve rapid measurements of cell biomechanics in a flow cytometer setup. Specifically, our stimulated Brillouin scattering flow cytometry can acquire at a rate of 200 Hz, with a spectral acquisition time of 5 ms, which marks a 10x improvement compared to previous demonstrations of spontaneous Brillouin scattering flow cytometry. We experimentally validate our stimulated Brillouin scattering flow cytometer by measuring cell populations of normal breast epithelial cells and metastatic breast epithelial cancer cells.

Advantages of integrating Brillouin microscopy in multimodal mechanical mapping of cells and tissues.

Recent research has highlighted the growing significance of the mechanical properties of cells and tissues in the proper execution of physiological functions within an organism; alterations to these properties can potentially result in various diseases. These mechanical properties can be assessed using various techniques that vary in spatial and temporal resolutions as well as applications. Due to the wide range of mechanical behaviors exhibited by cells and tissues, a singular mapping technique may be insufficient in capturing their complexity and nuance.

Macrophage mediated mesoscale brain mechanical homeostasis mechanically imaged via optical tweezers and Brillouin microscopy .

Tissues are active materials where epithelial turnover, immune surveillance, and remodeling of stromal cells such as macrophages all regulate form and function. Scattering modalities such as Brillouin microscopy (BM) can non-invasively access mechanical signatures at GHz. However, our traditional understanding of tissue material properties is derived mainly from modalities which probe mechanical properties at different frequencies.
