Please join me welcoming Hannah Rydman to Clemson!

Hannah has recently accepted our offer to become a Lab Specialist in our Department and will help us preparing for the General Chemistry and Organic labs. Hannah graduated from Bob Jones University with a BS in Cell Biology and a Chemistry minor. Since 2016 she was a lab assistant at Bob Jones and has also worked for Cayman Chemical doing organic synthesis.

To limit the spread of the virus in our department and in line with the current recommendation from the CDC (https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/diy-cloth-face-coverings.html), starting May 6, everyone coming to Hunter Chemistry Lab will be required to wear a face mask and exercise strict social distancing measures. Everyone is also strongly encouraged to follow established prevention measures (https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/prevention.html). People working in other buildings (BRC, AMRL, etc) should contact the corresponding building managers.

We understand the hassle of having to make your own masks to work but please keep in mind that these masks need to be frequently washed so it is a lot simpler/safer to do it this way. If you bring a couple of those masks, you may swap them and take them home in a Ziplock bag for washing. If you need help, the following link contains instructions on how to make face masks either with or without sawing (https://www.wired.com/story/how-to-make-a-cloth-face-mask/). Many other tutorials are available. To help with this issue, the department has already purchased a small batch of masks from Fisher that can be used as last resource. This link that describes HOW to wear/discard face masks. The link also has a number of infographics that can be also used https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public/when-and-how-to-use-masks

The table includes counts of all research outputs for Clemson University published between 1 December 2018 – 30 November 2019 which are tracked by the Nature Index. Each year, the Nature Index publishes tables based on counts of high-quality research outputs in the previous calendar year. Read more

Users please note:

• The data behind the tables are based on a relatively small proportion of total research papers, they cover the natural sciences only and outputs are non-normalized (that is, they don’t reflect the size of the country or institution, or its overall research output).
• The Nature Index is one indicator of institutional research performance. The metrics of Count and Share used to order Nature Index listings are based on an institution’s or country’s publication output in 82 natural-science journals, selected on reputation by an independent panel of leading scientists in their fields.
• Nature Index recognizes that many other factors must be taken into account when considering research quality and institutional performance; Nature Index metrics alone should not be used to assess institutions or individuals.
• Nature Index data and methods are transparent and available under a creative commons licence at natureindex.com.
• The Nature Index database undergoes regular updating, corrections, adjustment of institutional hierarchies, and removal of retracted papers and thus the live website can differ from the frozen annual tables.
• *The change in adjusted Share accounts for the small annual variation in the total number of articles in Nature Index journals. Share values have been adjusted to 2019 levels to calculate the percentage change. For more information on the adjustment, please see the Adjusted metric explainer.
