Hi, I just did my first Linux install (Kubuntu) onto an external NVME drive. It boots fine on my laptop but gives me a "MBR error, insert floppy" screen when I try to run it on my desktop. On the motherboard settings the drive shows as a bootable option but without a UEFI label. What issues could cause this? From what I've read it seems like a boot loader problem but I have no idea why it would be fine on one device but not another. I tried to update the motherboard firmware but the file the manufacturer provides wasn't working. It's running a 2021 version.

Edit: I figured it out. The issue had nothing to do with my Linux installation. My motherboard had a hidden option to change the UEFI boot order, which is entirely separate from choosing which drive to boot from.

This was my first time soldering and it went pretty well. On booting it up the LEDs weren't working on one side and one key wasn't registering, a quick hit with the iron got it going fine.

Using a technique called high-resolution liquid cell transmission electron microscopy (LC-TEM) at the Molecular Foundry, the researchers captured real-time, atomic-scale LC-TEM videos of Cd-CdCl2 CSNPs ripening in solution.

Fully solid-state lithium batteries offer some key advantages over the current liquid electrolyte based systems. But these solid electrolytes under development can be unreliable and their degradation mechanisms are unclear. This investigation employed transmission electron microscopy (TEM) to study the evolution of these materials while they operate. They found that differences between the expansion of the cathode material and solid electrolyte induced delamination at their interface. They also noted microscopic cracks forming in the cathode material, and reduction of LCO to metallic Co when the potential was allowed to drop below 1.5 V vs Li/Li+.
