Deep reconditioning of batteries during DSCS 3 flight operations [PDF]

open access: yes
Deep reconditioning of batteries is defined as discharge below the 1.0 volt/cell level to a value of about 1.0 volt/battery. This type of reconditioning was investigated for use on the Defense Satellite Communications System (DSCS) spacecraft, and has ...

Human Skin Models in Biophotonics: Materials, Methods, and Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
This review discusses how the optical properties of human skin can be replicated in human skin models. It describes the principles, materials, and techniques used to develop artificial skin for biophotonics research. Finally, the article highlights recent advances and shows how these models improve the study of light‐skin interactions without the need ...

Printing and Rerouting of Elastic and Protease Responsive Shape Memory Hydrogel Filaments

open access: yesAdvanced Healthcare Materials, EarlyView.
A biofabrication strategy, Rerouting of Free‐Floating Suspended Hydrogel Filaments (REFRESH), is developed enabling the printing of highly elastic, reconfigurable protease‐responsive hydrogel filaments with shape memory properties. The filaments can be manually braided, knotted, and rerouted to create intricate cell‐laden 3D architectures, expanding ...

HF Radar Observations and Modeling of the Impact of the 8 April 2024 Total Solar Eclipse on the Ionosphere‐Thermosphere System

open access: yesGeophysical Research Letters
The path of totality of the 8 April 2024 solar eclipse traversed the fields‐of‐view of four US SuperDARN radars. This rare scenario provided an excellent opportunity to monitor the large‐scale ionospheric response to the eclipse.

Solvothermal Template‐Induced Hierarchical Porosity in Covalent Organic Frameworks: A Pathway to Enhanced Diffusivity

open access: yesAdvanced Materials, EarlyView.
Hierarchically porous covalent organic frameworks (hCOFs) are constructed using a solvothermal template‐induced synthetic strategy. Commercially available zinc oxide nanoparticles are employed as hard template enabling an increase in total pore volume in a series of COFs.
