A belated year in review 2021<\/strong><\/h2>\n

Before we get to the 21 best photochemistry papers of 2021, we want to look back at the year. And at HepatoChem, we had a VERY big year in 2021. We started shipping our new photoreactor the Lucent360™, added members to our team, moved into a new lab space and built out a new manufacturing facility. The year 2022 promises even more, new products, more exciting photochemistry, and hopefully more fun posts in our blog<\/a>.<\/p>\n

Last year at this time, while looking ahead towards a long cold COVID filled winter, we decided to look back at the year 2020 with a fun little piece listing our favorite papers of the year<\/a>. Now, everything has changed. COVID has gone away, the world has returned to normal, and everyone’s reagents and supplies are showing up on time. Little did we all know then that 2020 would never end. So, as we head into the 25th month of 2020, we try again to look back at the past 12 months of visible-light photocatalysis, photoredox, and synthetic photochemistry (really, we all need to just agree on a single term). Everything else arrived late in the past year, why not this?<\/p>\n

Last year, we estimated that there were a few thousand visible light photochemistry papers published in 2020, which seemed like a lot. Now as we look back at 2021, there is likely several times more. We’ve even reached the point where we are seeing papers titled \u00ab\u00a0Light-free catalysis…\u00a0\u00bb (not to call anyone out, but this used to be called catalysis). It continues to amaze us the amount of great work being published out there, especially with all the hardships and difficulties day to day endured just simply to get to work in the lab. As we described last year, these are our favorite 21 photocatalysis papers from 2021. This is not a list that attempts to find the best, or most viewed, or most famous 21 papers from the year. (We don’t have the time, energy, or interest in something that exhaustive and complex). Last year, we described our general criteria here<\/a>. Instead, thislist of the 21 must-read photochemistry papers of 2021 are simply ones that we thought were the best, funniest, oddest, most interesting, or downright unexpected<\/strong>. There are no bonus points for using any of our products, but I can’t say it wouldn’t help either.<\/p>\n

As a few added rules, this year, we eliminated from contention any paper using the terms variant, strain, antibody, viral, or anti-viral. So, we apologize. Even if your paper \u00ab\u00a0A new photocatalytic variant of the Minisci reaction for labeling coronavirus antibodies\u00a0\u00bb is the greatest piece of literature ever prepared, we won’t be reading it or highlighting it to avoid triggering our audience in this hellscape that we live. To answer a comment from our list from last year, our focus is definitely biased towards synthetic photoredox. So, all the great papers out there in more traditional photochemistry, solar cell, energy research and materials are generally not on our radar and likely not included on this list. If you have made that list, send it our way, we would love to read it. So, let’s have some fun. Keeping reading for our favorite papers from 2021 and then send us your favorites on twitter (@EvoluChem) or at info@hepatochem.<\/p>\n

A belated year in review 2021<\/strong><\/h1>

At HepatoChem, we had a big year in 2021. We started shipping our new photoreactor the Lucent360\u2122, added members to our team, moved into a new lab space and built out a new manufacturing facility. The year 2022 promises even more, new products, more exciting photochemistry, and hopefully more fun posts in our blog<\/a>. Last year at this time, while looking ahead towards a long cold COVID filled winter, we decided to look back at the year 2020 with a fun little piece listing our favorite papers of the year<\/a>. Now, everything has changed. COVID has gone away, the world has returned to normal, and everyone\u2019s reagents and supplies are showing up on time. Little did we all know then that 2020 would never end. So, as we head into the 25th month of 2020, we try again to look back at the past 12 months of visible-light photocatalysis, photoredox, and synthetic photochemistry (really, we all need to just agree on a single term). Everything else arrived late in the past year, why not this?<\/p>

Last year, we estimated that there were a few thousand visible light photochemistry papers published in 2020, which seemed like a lot. Now as we look back at 2021, there is likely several times more. We\u2019ve even reached the point where we are seeing papers titled \u201cLight-free catalysis\u2026\u201d (not to call anyone out, but this used to be called catalysis). It continues to amaze us the amount of great work being published out there, especially with all the hardships and difficulties day to day endured just simply to get to work in the lab. As we described last year, these are our favorite 21 photocatalysis papers from 2021. This is not a list that attempts to find the best, or most viewed, or most famous 21 papers from the year. (We don\u2019t have the time, energy, or interest in something that exhaustive and complex). Last year, we described our general criteria here<\/a>. Instead, this\u00a0list of the 21 must-read photochemistry papers of 2021 are simply ones that we thought were the best, funniest, oddest, most interesting, or downright unexpected<\/strong>. There are no bonus points for using any of our products, but I can\u2019t say it wouldn\u2019t help either.<\/p>

As a few added rules, this year, we eliminated from contention any paper using the terms variant, strain, antibody, viral, or anti-viral. So, we apologize. Even if your paper \u201cA new photocatalytic variant of the Minisci reaction for labeling coronavirus antibodies\u201d is the greatest piece of literature ever prepared, we won\u2019t be reading it or highlighting it to avoid triggering our audience in this hellscape that we live. To answer a comment from our list from last year, our focus is definitely biased towards synthetic photoredox. So, all the great papers out there in more traditional photochemistry, solar cell, energy research and materials are generally not on our radar and likely not included on this list. If you have made that list, send it our way, we would love to read it. So, let\u2019s have some fun. Keeping reading for our favorite papers from 2021 and then send us your favorites on twitter (@EvoluChem) or at info@hepatochem.<\/p>
