One of the main selling points of @chemicalscience.rsc.org was that it was diamond open access. I loved it. I was always happy to submit there. I recommended it highly. Now, it's going to be just another society journal taking grant money. No more ChemSci for me, if I can avoid it. ⚗️ #CompChem

In case you missed it: @chemicalscience.rsc.org now charges an APC of £2,850 per paper. It was previously free (diamond OA), and in my view it contributed greatly to the appeal and success of Chem Sci. Sad to see the RSC go that way…

For submissions from 1 July 2026 an APC will apply to all articles accepted in Chemical Science. Use our journal finder to check if your APC is covered by an institutional agreement with us. Note, if your institution has an agreement with us that covers APCs, you will be notified of this at article acceptance. Details of the APC and discounted rates are found here.

Get your manuscript submission ready with our submission checker tool. You can instantly check against Chemical Science's guidelines and requirements, and receive helpful hints to get you ready to submit.

@shl, I have been migrating my posts to a new location, and just now did this one :) https://egonw.github.io/blog/2010/07/17/setting-up-local-semantic-wiki-with.html

Setting up a local Semantic MediaWiki with RDFIO and SPARQL support

My now former student Samuel is doing a really cool Google Summer of Code project on import and export of RDF from a Semantic MediaWiki server. His screencast of today shows very nicely where things are going! So, time to get something installed on my Ubuntu system, based on Samuel description here: 1. `sudo aptitude install mediawiki-extensions php-apc imagemagick texlive-latex-base gs-gpl cjk-latex` 2. configure MediaWiki 1. `zcat /usr/share/doc/mediawiki/README.Debian.gz | more` 2. follow instructions on http://www.mediawiki.org/wiki/Manual:Installing_Mediawiki_on_Ubuntu_10.04 3. create a MySQL account as described here 4. do config stuff at http://localhost/mediawiki/config/index.php 3. set up a save place for local checkouts for MediaWiki extensions 1. `sudo mkdir -p /usr/local/lib/mediawiki/extensions` 2. `sudo chown egonw:egonw -R /usr/local/lib/mediawiki` 4. configure Semantic MediaWiki 1. `cd /usr/local/lib/mediawiki/extensions` 2. `svn checkout http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/SemanticMediaWiki/` 3. `cd /var/lib/mediawiki/extensions` 4. `sudo ln -s /usr/local/lib/mediawiki/extensions/SemanticMediaWiki` 5. `sudo nano /var/lib/mediawiki/LocalSettings.php` 1. add: `include_once("/var/lib/mediawiki/extensions/SemanticMediaWiki/SemanticMediaWiki.php");` 2. add: `enableSemantics('localhost');` 3. add: `$smwgShowFactbox= SMW_FACTBOX_NONEMPTY;` 6. visit http://localhost/mediawiki/indSpecial:SMWAdminSpecial:SMWAdminex.php/Special:SMWAdmin Next step is to install Samuel’s extension in its requirements: 1. set up the required extensions SMWWriter and POM: 1. `cd /usr/local/lib/mediawiki/extensions` 2. `svn checkout http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/SMWWriter/` 3. `svn checkout http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/PageObjectModel/` 4. `cd /var/lib/mediawiki/extensions` 5. `sudo ln -s /usr/local/lib/mediawiki/extensions/SMWWriter` 6. `sudo ln -s /usr/local/lib/mediawiki/extensions/PageObjectModel/` 2. apply the patch (where is it filed upstream?) 1. `cd SMWWriter` 2. `wget http://saml.rilspace.com/smwwriter-fixesfor-rdfio-20100716-r2.patch` 3. `patch -p0 < smwwriter-fixesfor-rdfio-20100716-r2.patch` 3. set up the RDFIO work from Samuel 1. `cd /usr/local/lib/mediawiki/extensions` 2. `mkdir RDFIO` 3. `cd RDFIO` 4. `svn checkout http://smwrdfio.googlecode.com/svn/trunk/ .` 5. `sudo nano /var/lib/mediawiki/LocalSettings.php` 1. and add the RDFIO blob given on Samuel’s Install page 4. install ARC2 1. `cd /usr/local/lib/mediawiki/extensions/SemanticMediaWiki/libs` 2. `wget http://code.semsol.org/source/arc.tar.gz` 3. `tar zxvf arc.tar.gz` 5. install the RDFIO pages onto the main page for easy access, add: 1. `[[Special:ARC2Admin|ARC2Admin]]` 2. `[[Special:RDFImport|RDFImport]]` 3. `[[Special:SPARQLEndpoint|SPARQLEndpoint]]` That’s it. Not quite the 5 minutes that Samuel promised me, but I’m happy to have this available for my conference tour next month! I installed the default RDF, and got the nice default wiki page to which I can now start adding manual annotation: If you are wondering about the use case, this RDF import is ideal for building up knowledge bases, as detailed in my Critical mass for Open Notebook Science wikis by prepopulation with RDF data post last month. Just aggregate the info on the web you can find (yes, that’s another story), put it in your wiki and complement it with your local knowledge, import into Bioclipse, and run your analyses to verify your hypotheses! Thanx to Samuel for this really great work! __` rdf` __` sparql` __` wiki` __` bio2rdf` __` bioclipse`

🧪 What is TFA, and why has EFSA updated its advice? TFA can end up in food, soil and water. After reviewing new evidence, EFSA has lowered the safe level for dietary exposure by 3.5 times. Evidence shows #TFA can affect thyroid hormone levels. Learn more: link.europa.eu/BjyknW #FoodSafety #PFAS

EFSA lowers safe level for exposure to TFA

The European Food Safety Authority (EFSA) has reduced the safe level of trifluoroacetic acid (TFA) in the diet based on new scientific evidence. TFA is a breakdown product of some pesticides.

🍦 We couldn't let yesterday's #WorldIceCreamDay pass without celebrating lipids! More than flavour carriers, milk lipids help determine ice cream's texture, creaminess, stability, and melt behaviour. Recent research highlights how milk fat structure shape these sensory qualities.
