Fluid Shifts: The crew performed eye examinations using the Fundoscope in support of the Fluid Shifts study. Fluid Shifts is a NASA investigation, divided into Dilution Measurements, Baseline Imaging, and Imaging with Chibis. The Chibis hardware is used to perform the Lower Body Negative Pressure (LBNP) part of the experiment. The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut’s eyes. Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a LBNP device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and prevention of eye damage.

This means the tanks required by hydrogen-powered vehicles designed to travel long distances without refuelling are prohibitively large and heavy.

In contrast to forming SEI between Li and solid electrolytes, electronic conducting (such as Au, Si, and Ge) layers between Li and solid electrolytes are also reported to enhance the Li wettability to solid electrolyte, thus suppressing the Li dendrites. Since CE is a sensitive indicator for Li dendrite growth and stability between the electrolyte and the Li metal, the CEs for Li plating/striping in three LPS electrolytes (LiFSI-coated/infiltrated LPS, Au-coated LPS, and pristine LPS electrolytes) were evaluated using Swagelok SS|electrolyte|Li half cells where stainless steel (SS) served as a current collector. Au-coated LPS was prepared by coating a 10-nm layer of Au on both sides of the LPS electrolyte surface. Similar CE of 86 to 90% was obtained for both SS|LPS|Li and SS|Au@LPS|Li cells (Fig. 3, A and B), indicating that the Au coating cannot block the parasitic reactions between the SSE and the Li metal, although the Li plating/stripping polarization was reduced because of the enhancement of the contact areas between the LPS and the Li metal (Fig. 3B). For the Au-coated LPS electrolyte, once the Au contacts with the Li metal, it will instantly form the fully lithiated Li15Au4 phase. This highly conductive alloy layer tightly adhering to the Li metal has the same potential as the Li metal. Although a better contact between LPS and Li reduces the Li plating/stripping overpotentials, it cannot block any side reactions between the SSEs and the Li metal anode. It should be pointed out that recently, Sakamoto and colleagues also found that the Au interlayer could not increase the critical current density in the LLZO garnet SSE system either (25). For the LiFSI-treated LPS cell, residual LiFSI will react with the deposited Li metal to form an LiF-rich SEI in the initial Li plating process, resulting in an initial CE of 72%, which is lower than the CE of the untreated LPS cell (86%) or the Au-coated LPS cell (88%). However, after several activation cycles, the CE for LiFSI-coated/infiltrated LPS significantly increased to ~98% (Fig. 3, C and D), while the CEs of the untreated LPS cell and the Au-coated LPS cell are only 85 to 90%. The in situ–formed LiF-rich SEI reduces the contact resistance and effectively suppresses the Li dendrite growth and side reactions between the LPS electrolyte and the Li metal. Therefore, a very high cycling CE for the LiFSI-coated/infiltrated LPS is achieved after the initial few activation cycles. Although there is some nonuniformity for the in situ–formed SEI layer in terms of physical morphology and chemical composition along the Li surface, compared with the high electron-conductive layers formed between the SSEs and the Li metal, this electronic insulating LiF-rich SEI can effectively improve the critical current density and suppress the Li dendrites in SSEs. Without this layer, the in situ–formed interphase with high electron conductivity due to the reaction between the SSEs and the Li metal can promote the Li dendrite formation in the SSEs.

"It is not just Sonora’s finance package that would be substantially de-risked, we would also gain access to Ganfeng’s proven expertise in developing lithium projects, thereby significantly de-risking the construction phase at Sonora.  In return, Ganfeng gains exposure to a large and scalable lithium project which, with estimated life-of-mine operating costs of about $4 000/t of Li2CO3, has the potential to become one of the lowest cost suppliers of battery grade lithium to fast-growing industries, such as electric vehicles and energy storage, for many years to come,” he explained.
