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.

The journal reports an "ISI impact factor".[9] This impact factor is not from the Institute for Scientific Information (ISI) or its successor Clarivate, but from a company named International Scientific Indexing.[10][11]

The journal was listed in the updated Beall's List of potential predatory open-access journals.[1] It has been criticized for sending out email spam to scientists, calling out for papers for the journal.[6]

In March 2020, the journal published the fake research paper "Cyllage City COVID-19 outbreak linked to Zubat consumption". The paper blamed a fictional creature for an outbreak of Covid-19 in a fictional city, cited fictional references (including one from author Bruce Wayne in a made-up journal named "Gotham Forensics Quarterly" on using bats to fight crime), and was cowritten by fictional authors such as Pokémon’s Nurse Joy and House, MD.[14] The author was a scientist from National Taiwan University, who acted under a pseudonym.[2] Four days after submission the paper was accepted for publication. Since the line in the article “a journal publishing this paper does not practice peer review and must therefore be predatory” was not objected to, the submitting author concluded that the paper had not been reviewed at all.[15] The paper was later removed as the author did not pay the publication fees.[2]

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.

A. Collier, Astrophysics Ph.D. talks about the current culture surrounding postdoctoral positions. And how unsustainable they are. I love her channel 😁

Call me Tony! I'm a Ph.D. student studying materials science, which is essentially the creation and measurement techniques used for solids. For me it's basically a specialization within chemistry. My interests focus around functional materials for renewable energy storage and energy conversion. So all new and exciting things in batteries, supercapacitors, solar cells, thermoelectrics, condensed matter physics. I'm very excited to join this community and participate in many productive discussions both in and outside my field 😁. I also hope my contributions can help this instance grow, if just a little. Feel free to send me any questions you have about related topics!

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+.

Has anyone else encountered this? I can log in on my phone just fine (browser and Liftoff app). But when I try in Chrome or Firefox on Windows it says things like "Unexpected token O, Origin is... not valid JSON" and "SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data".
