Research data and the “h-index”.

Monday, June 24th, 2013

The blog post by Rich Apodaca entitled “The Horrifying Future of Scientific Communication” is very thought provoking and well worth reading. He takes us through disruptive innovation, and how it might impact upon how scientists communicate their knowledge. One solution floated for us to ponder is that “supporting Information, combined with data mining tools, could eliminate most of the need for manuscripts in the first place“. I am going to juxtapose that suggestion on something else I recently discovered.

Digital repositories. An update to the update.

Monday, August 13th, 2012

A third digital repository has been added to the two I described before. Chempound is a free open-source repository which (unlike DSpace and Figshare) was developed specifically for chemistry.

QR codes and InChI strings.

Sunday, July 22nd, 2012

A month or so ago at a workshop I was attending, a speaker included in his introductory slide a QR (Quick Response) Code. It is a feature of most digital eco-systems that there is probably already “an app for it”. So I thought I would jump on the band wagon by coding an InChI string. Here it is below:

Digital repositories. An update.

Saturday, July 21st, 2012

I blogged about this two years ago and thought a brief update might be in order now. To support the discussions here, I often perform calculations, and most of these are then deposited into a DSpace digital repository, along with metadata. Anyone wishing to have the full details of any calculation can retrieve these from the repository. Now in 2012, such repositories are more important than ever.

Connections in chemistry. Anti-malaria drug ↔ organocatalysis.

Thursday, July 5th, 2012

Back in 1994, we published the crystal structure of the molecule below (X=H), a putative anti-malarial drug called halofantrine. Little did we realise that a whole area of organo catalysis based on a thiourea catalyst with a similar motif would emerge a little later. Here is how the two are connected.

The Dieneone-phenol controversies.

Monday, April 30th, 2012

During the 1960s, a holy grail of synthetic chemists was to devise an efficient route to steroids. R. B. Woodward was one the chemists who undertook this challenge, starting from compounds known as dienones (e.g. 1) and their mysterious conversion to phenols (e.g. 2 or 3) under acidic conditions. This was also the golden era of mechanistic exploration, which coupled with an abundance of radioactive isotopes from the war effort had ignited the great dienone-phenol debates of that time (now largely forgotten). In a classic recording from the late 1970s, Woodward muses how chemistry had changed since he started in the early 1940s. In particular he notes how crystallography had revolutionised the reliability and speed of molecular structure determination. Here I speculate what he might have made of modern computational chemistry, and in particular whether it might cast new light on those mechanistic controversies of the past.

The blog post as a scientific article: citation management

Monday, February 27th, 2012

Sometimes, as a break from describing chemistry, I take to describing the (chemical/scientific) creations behind the (WordPress) blog system. It is fascinating how there do seem increasing signs of convergence between the blog post and the journal article. Perhaps prompted by transclusion of tools such as Jmol and LaTex into Wikis and blogs, I list the following interesting developments in both genres.

Shared space (in science).

Friday, January 6th, 2012

I thought I would launch the 2012 edition of this blog by writing about shared space. If you have not come across it before, it is (to quote Wikipedia), “an urban design concept aimed at integrated use of public spaces.” The BBC here in the UK ran a feature on it recently, and prominent in examples of shared space in the UK was Exhibition Road. I note this here on the blog since it is about 100m from my office.

Mobile-friendly solutions for viewing (WordPress) Blogs with embedded 3D molecular coordinates.

Sunday, December 11th, 2011

My very first post on this blog, in 2008, was to describe how Jmol could be used to illustrate chemical themes by adding 3D models to posts. Many of my subsequent efforts have indeed invoked Jmol. I thought I might review progress since then, with a particular focus on using the new generations of mobile device that have subsequently emerged.
