A Special Request from Pacifichem 2021

Owing to the COVID-19 Pandemic and the additional costs that we have incurred in delaying the meeting for a year and adding virtual content, Pacifichem 2021 is now in a very tight financial situation. If you are in a position to not use a voucher, or to otherwise help our bottom line by encouraging additional attendees or financial donations, we would greatly appreciate it! Thank you.
