Interesting. Sadly, I just checked and it seems we don't have access to the show. It's a common issue in Thailand.

I've tried many times to get into LotR, but somehow it's not for me.

But on the broader point of the movies, I do think that we need better story telling. Most movies are now francishes.

I'd like to see new characters, exploring new themes.

408 vibrational modes of the CuSCN-MBTz complex from a recent paper I worked on.
The vibrational frequencies are translated to audio, with volume decided by Raman activity, sweeping up from low frequency to high frequency.

Near-Infrared Luminescence from Transparent Thin Films of Copper(I) Thiocyanate Modified with 2-Mercaptobenzothiazole via Excited-State Symmetry Breaking Near-infrared (NIR) emission in molecular materials is typically achieved by narrowing the band gap through extended π-conjugation or heavy-atom substitution.

This was fun! The material has a staggeringly large Stokes shift when in solution or thin spin-coated films, but not in bulk crystal phase. I got to calculate the crystal's Raman spectrum and analyze the contribution of intermolecular vibrational modes.

Yeah, we are more focused on the outcomes. But we do occasionally have these issues.

It is a major reason that we now process the different temperatures together, so the CIFs are consistent.

I've used NTf2 quite a bit and in our systems it's generally quite well behaved, although we do have complexes where things are more.. problematic.

It was the first space shuttle mission I remember.

There had been so many missions and going up now seemed trivial, easy.

As we learned that day, not so.

Near-Infrared Luminescence from Transparent Thin Films of Copper(I) Thiocyanate Modified with 2-Mercaptobenzothiazole via Excited-State Symmetry Breaking Near-infrared (NIR) emission in molecular materials is typically achieved by narrowing the band gap through extended π-conjugation or heavy-atom substitution. Here, we report an unconventional route─excited-state symmetry breaking─that enables NIR emission while preserving a wide band gap. Copper(I) thiocyanate (CuSCN), a transparent semiconductor with optical activity normally observed only in the ultraviolet region, forms a dimeric complex with 2-mercaptobenzothiazole (MBTz). In thin films, CuSCN-MBTz complex exhibits NIR photoluminescence at 800 nm, while retaining a large optical gap (>3 eV), resulting in a transparent NIR-emissive material with a large Stokes shift of ∼15,000 cm–1. Structural and spectroscopic analyses reveal that, unlike the rigid crystalline phase, the film state allows molecular reorganization of Cu2(SCN)2(MBTz)4 dimers, which induces symmetry breaking and lowers the energy of the emissive state without reducing the band gap, in contrast to typical Cu(I) emitters. This work provides a new photophysical mechanism for generating long-wavelength emission from wide-band gap, earth-abundant Cu(I) systems and widens the functional scope of CuSCN materials.

Really pleased to see this paper published in Inorg Chem @pubs.acs.org with my good friend Prof Pichaya from VISTEC, with help from NZ and Japan.

A Stokes shift of 15,000 cm-1 was not at all what we were expecting with these compounds!

Hi, if you're a student or postdoc, living in the US, going to #IUCr2026, we at the American Union of Crystallography want to give you money.

New deadline: May 1st.

I remember going to the US on sabbatical and despite eating carefully, I still put on significant weight.

As they say you are what you eat. That for me is where the problem lies. The US needs to find ways to improve what is available and affordable for their people.

I almost never pay, but the last time I did it was around $1,000. Getting funds from grants has become really hard and there's no question that I look at this before submitting.

Some journals are just unaffordable for me.

I really enjoyed reading the paper and it's great to see the extra detail that you've revealed here.

As our group works on Fe(III) SCO systems is always great to see new work in the area.

I think that within a generation most Brits won’t understand most imperial units, if the UK can keep parties like Reform out of government.

Pro-tip for ERCs

Don't resubmit a paper to a different journal where a referee has asked for extensive changes.

Chances are you'll get the same referee who's not going to be pleased!

Sad to see that it's not only Thailand where funding for discovery science has completely disappeared.

The role that this has in creating thinkers who study a problem deeply and then formulate a solution is really not understood by politicians.

This is true of many such companies. I do find myself asking more lately what some of these people actually contribute to society.

Tech bros somehow remind me of Bond villains like in Moonraker where the guy just wants to replace the current population with 'perfect' humans.

This cartoon shows a boat labelled “Grantor” carrying a cargo of “IP”, “know how”. And a massive container that says “protect”. It’s trying to get away from an iceberg labelled “publish”. There is a cry from the grantor boat saying “faster faster”. Driving the iceberg is a submarine labelled “tenure board”. Ithere is also a cry from the submarine saying “faster faster”. Trailing behind these two is a researcher in a small boat with an outboard motor. The person is crying “wait up”!

The cartoon is meant to represent the tension between translational research funding, the pressure to achieve outcomes, and the pressure to produce outputs to meet the different metrics of the different bodies involved.

There's no way the Mg content is that high.

It's clear that this is a dihydrate which means that Mg content should be around 7.5%

I think there's a more important question here: why is the research so easily replaced by AI?

As a synthetic chemist, I couldn't get AI to do the work, even if I want to.

But it also makes me wonder have we focused too much on tangible targets in research? Where has knowledge creation gone?

I might have to come, if I can get funding.

This is an interesting thread that highlights the fact (for me at least) that research has become too much about the specific goal and we have lost the importance of the journey in research.
