One of the insidious features of cancer is that it has the ability to prevent the immune system from recognizing the diseased cells as ‘non-self.’ Immune checkpoint inhibitors, as chemotherapeutics, act to eliminate this feature of cancer and enable the immune system to attack it. Recently, researchers from Harvard Medical School, Hamad Bin… Show more
Density functional theory (DFT) is a powerful technique used in theoretical chemistry (and physics) that unfortunately can be quite difficult to explain. A short (yet complete) introduction to DFT is given by Klaus Capelle as a very nice, freely accessible, educational material. https://arxiv.org/abs/cond-mat/0211443 It also happen to be… Show more
Dear members of ACS community, I though it would be nice if theoretical chemists could share a compilation of some interesting simulation software. This is why I propose this - admittedly quite small - list of some of the codes I have been using or that I have worked with. Please feel free to expand or correct this document and/or to…
The American Chemical Society Green Chemistry Institute® was thrilled to host the Green Chemistry Challenge Awards ceremony in Washington, DC this week! ACS GCI coordinated this year’s nomination and review process in selecting the 2018 recipients: Tom Connelly, Jr. gives Prof. Frank Gupton his award. Photo credit: Peter Cutts Photography … Show more
By Mr. Philip Krook, Communications Officer, ChemSec Last week I heard a word that I had never heard before. It was a term explaining a phenomenon that has skyrocketed in the last years. The word was uberization. At the time, I could already guess the meaning behind the expression seeing as I knew about the company from which the term is… Show more
What is the perfect solution for preserving a rose using - H2O, Sodium Hypochlorite, and Acetic Acid?
I am trying to create a solution to preserve a rose in a globe for around 30 days. I am trying to mix water, with Sodium Hypochlorite, and Acetic Acid. I can not get the mixture correct. Any idea on the ideal amount of those three ingredients? I know that can be a dangerous mix and do not want to make chlorine gas. Any help would be great!
You are not clear in what it is you are trying to do. You are trying to preserve a rose in a globe - do you mean just the flower, or the flower with a stem? The approach you are mentioning here is similar to what flower distributors do with the water they put cut flowers in, but it is intended to discourage bacteria, mold and fungus from growing…
