In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Studying water and aqueous TMAO solutions under high pressure and supercritical conditions
Studies of water under extreme conditions (high and low temperatures, extreme pressures) are of particular scientific interest. Understanding the properties of water under extreme conditions is not only a fundamental prerequisite for a better understanding of geological and biological processes and the exploitation of various technical applications, but is also widely believed to be fundamental for a deeper understanding of the structure of water under ambient conditions . Under high pressures and temperatures to the supercritical regime, the structure of water and the hydrogen bond network show peculiar features, e.g. Clustering .
TMAO is an organic compound that is found in deep-sea fish in a concentration that is increasing with depth . It is also known that it may counteract pressure-induced destabilization of proteins. However, the influence of TMAO on hydrogen-bonding under high-pressure conditions has not yet been studied.
Our research project aims at investigating the change of hydrogen-bonding in water and aqueous TMAO solutions at high pressure and/or high temperature conditions by means of THz absorption spectroscopy. THz spectroscopy is an ideal tool to study the structural properties of water and aqueous solutions as it allows for a direct study of the intermolecular hydrogen-bond network. The principle of this spectroscopic technique and specific experimental challenges will be explained. Furthermore, first results of spectroscopic measurements of water under high pressure conditions will be presented.
