In an electrochemical cell, we allow electrons to be transferred, which will spontaneously occur in the direction of ΔG<0ΔG<0\Delta G <0, and a cell operating in this fashion is called a galvanic or voltaic cell, which can be used to provide energy to do work, like the common "battery" we use in flashlights and electrical devices.

It is important to understand the relationship of these graphs and the differences. The phase diagram represents the phase that would exist for a system at equilibrium as a function of the pressure and temperature. The ri

    1. macroscopic perspective of classical thermodynamics, and the microscopic description central to statistical mechanics. The classical approach defines entropy in terms of macroscopically measurable physical properties, such as bulk mass, volume, pressure, and temperature. The statistical definition of entropy defines it in terms of the statistics of the motions of the microscopic constituents of a system – modeled at first classically, e.g. Newtonian particles constituting a gas, and later quantum-mechanically (photons, phonons, spins, etc.). The two approaches form a consistent, unified view of the same phenomenon as expressed in the second law of thermodynamics, which has found universal applicability to physical processes.

    1. Plot of vapor pressure as a function of temperature for a variety of substances. It should be noted that this is a "bounded function", with the lower end being the melting point, and the upper end being the boiling point of a substance.

      This graph is important as it shows how you can determine trends in a physical property based on the structure of a molecule. Although water is lighter than diethyl ether and ethanol, it has stronger intermolecular forces holding it together and thus has a lower vapor pressure. This results in a higher boiling point.

    1. This is a very valuable resource for finding safety information on chemicals and it is structured so you can instantly find the source of that information

      You need to realize PubChem is a data aggregator that maintains the provenance of the data. And like anything, you have to analyze it. We have an activity where students find what appear to be conflicting safety recommendations, and are then asked to analyze it.

      This annotation is public, and anyone can see it, even without an account at hypothes.is. If we comment to a group, only the members of the group can see it.

    1. Discussions during the 2019 OLCC were entirely on the hypothes.is web annotation service, which had been integrated into LibreTexts, and was set up to send an email to students and faculty whenever an annotation was created. In future OLCCs, this notification needs to be extended to other types of social media because “email” is often not students’ preferred means for online communication, and these communications need to be across web platforms.

      We are essentially going to use the model that evolved out of the cheminformatics OLCC, using hypothes.is with LibreText. But I expect much more use of external links as students figure how to do code, and use code libraries as they try and set up sensors to Raspberry Pis.

    1. The publication industry owns science In addition to shaping the content of science, researcher evaluation policies focused on publication statistics contribute to what is essentially a publication industry oligopoly that undermines user access to the research that is published. Because of entrenched journal hierarchies, codified by journal impact factor scores, a handful of large corporate publishers have secure positions in owning “must publish” outlets for scientists. For example, the RELX Group—the corporate owner of the publisher Elsevier, the Scopus database (an aspirational competitor to WoS), the prestigious journals Cell and The Lancet, and the publication database ScienceDirect, among other products—boasts in its 2018 annual report that its Scientific, Technical & Medical division organized “the review, editing and dissemination of 18% of the world’s scientific articles.” By its numbers, the group received a whopping 1.8 million article submissions to 2,500 journals, overseen by 20,000 editors and countless peer-reviewers, and in the process reaped $3.3 billion in revenue. Subscriptions constituted 74% of that revenue. To achieve those revenues, the group continues to expand its offerings: Elsevier published 60% more articles in 2018 than a decade prior.

For the 13 elements with standard atomic-weight intervals(hydrogen, lithium, boron, carbon, nitrogen, oxygen, magnesium, silicon, sulfur, chlorine, argon, bromine, and thallium), the standard atomic weight is given as an interval to stress that standard atomic weights are not constants of nature [6]. Each is shown as lower and upper bounds (limits) (Figs. 1.1 and 1.2). Some users of atomic-weight data need a value that is not an interval, such as for purposes of trade and commerce. For these users, a conventional atomic-weight value[4]is

      are we editing this for "American" English? I would think "can" instead of "may" is better

    7. eaxys uses severalhundred algorithms to interpret the queryand directly gives answers that may be in Document, Substanceand/or ReactionRecords

      Is there a place where further documentation on this can be found. I have Thibault's article from the ACS symposium series book, and will look this up there.

    1. and we may want to review all reactions regardless of whether yields are quoted.

      So if a yield is not reported, the planner will not show it unless you set this to zero % yield, right?

    1. This video shows how one could use the ability to aggregate annotations at the bottom of a page to prepare for in-class lecture.

      This video shows how hypothes.is annotations was used in flipped classroom lecture preparation.

    1.  Chemical informatics for facilitating international collaboration This activity aims at creating a working group of scientists to collaboratively source, collate, and analyse data with unique chemical signatures. It seeks to compile data collected from a broad range of routine chemical monitoring activities that contain chemical signatures (e.g. data collected from atmospheric monitoring, environmental sample collection, water testing, and more). The intent is to connect chemical and information scientists from different regions of the world to create a hub in which the information can be disseminated to the collaborators for visualisation and informative analysis of global and regional chemistry. This work is intended to facilitate engagement of the Technical Secretariat with the scientific community. Main output will be a data collation centre serving as a hub for collating and reducing data into formats compatible with the analytical tools used by the collaborating researchers. The hub, located in one of the participating universities, will support the network of collaborating scientists and build its capacity to expand beyond the implementation period.

      I believe a small EU grant has been awarded to look into this, although the funds are not available for us, we could support this, and piggy back off of it.

    1. e textile industry is one of the oldest and largest industries on a global level, and while dyes and pigments of natural origin have been used for coloring clothing and other purposes since 3000 BC, it is only within the past 200 years that a wide variety of synthetic dyes have begun to be produced in massive quantities.[20, 21] Textiles are classified based on the material they are made of, which in turn dictates the type of dye which is used to impart them with color; for instance, reactive, direct, and indigo dyes are used for cellulose fibers, while acid dyes are used for protein fibers and both basic and dispersed dyes are used for synthetic fibers.[22] The structures of several common dyes used for textiles, paper, foo

      Note, you can't use stars, but need to use the "contains" option

    2. EMTREE drug terms listed in the Index Terms

      EMTREE is like Mesh, but how do you get to the index terms, Unfortunately, h. will not link inside of Reaxys, and so I can't give a link to where I am

    1. identity search.
    2. Getting molecular properties of a set of compounds

      It seems most of the things we can get are from the advanced search (entrez?) options. Can we get other items, like boiling points?

    1. PubChem subgraph fingerprints,

      Why are these called a "Subgraph"? I see this from , wikipedia. Is it that each bit of the fingerprint represents a subgraph of the molecule, which in it self is the graph? That is, its existance/nonexistance of this subset within the entire?.

    1. without minor isotopes by combining the retrieved search results [from (a)] with the following Entrez indices:

      once you have done this, click on the number of hints, go to the doc sum page, go to advanced, and use the advanced query builder to perform the filters.
