An International Laboratory Comparison Study on Approximating the Enthalpy of Adsorption via the Clausius‐Clapeyron Approach Adsorbate–adsorbent interaction is often quantified via the isosteric enthalpy of adsorption, ΔHst. Commonly, ΔHst is determined indirectly by applying the Clausius-Clapeyron (CC) equation to adsorpt...

I'm really pleased to have been involved in this interlaboratory study, now published in ChemPhysChem.

If you calculate and/or publish isosteric enthalpies of adsorption, please take a look. We found a lot of variation in determined values...

I forget: is the proper order:

Sock - shoe - sock - shoe

Or:

Sock - sock - shoe -shoe

First is more efficient in leg movement terms.

Endometriosis is an incredibly interesting disease 5k words, 23 minutes reading time

Note the analysis on the discordance between the health and economic burden of endometriosis vs relative federal investment in research. TL:DR, very bad.

A black-and-white historical photograph of Dr. Maud Leonora Menten (1879–1960), the Canadian physician and biochemist who co-developed the Michaelis–Menten equation for enzyme kinetics. Taken in her laboratory (likely at the University of Pittsburgh in the 1910s–1920s), she stands with a serious, focused expression—lips closed, eyes direct and thoughtful—against a backdrop of wooden shelves filled with glass bottles, jars, scientific equipment, and a wire-mesh enclosure. She wears a dark dress with a lace collar, a string of beads, and her hair styled in a neat bun. Superimposed on the image is the Michaelis–Menten equation in white text:v=Vmax⁡[S]Km+[S]v = \frac{V_{\max} [S]}{K_m + [S]}v = \frac{V_{\max} [S]}{K_m + [S]}
This iconic portrait captures Menten during her groundbreaking research in biochemistry and histochemistry, where she helped establish the foundational mathematical model of enzyme-substrate reactions still used today, while overcoming significant gender barriers as one of the first women in Canada to earn both an M.D. and a Ph.D.

Chemist/physician Dr. Maud Menten co-authored the seminal paper 𝘋𝘪𝘦 𝘒𝘪𝘯𝘦𝘵𝘪𝘬 𝘥𝘦𝘳 𝘐𝘯𝘷𝘦𝘳𝘵𝘪𝘯𝘸𝘪𝘳𝘬𝘶𝘯𝘨, 1931. This intro'd the Michaelis–Menten equation (image). It remains a cornerstone of #biochemistry, used in drug design, metabolic studies & enzyme engineering. She was born #OTD in 1879.

The APS Global Physics Summit is in full swing!

Such large conferences are always a bit overwhelming, so I'm starting a thread to digest it from my point of view as a computational biophysicist.

A theoretical framework for random acceleration molecular dynamics simulations The dissociation of a ligand bound to a receptor is a rare event occurring on a timescale that is far longer than can be afforded by standard simulation methodo

We developed a simple theory and showed that Random Acceleration Molecular Dynamics (RAMD) is consistent with a Smoluchowski equation with an effective temperature and diffusion coefficient that depend quadratically on the magnitude of the random force.

I was invited, for July, to a scienctific meeting in Telluride (Colorado). I was told it is a wonderful place for a conference, and I was very much looking forward to an exciting meeting in a fantastic environment. I have just canceled my participation, despite having booked already everything.

The currently proposed budget changes to NIH and NSF have absolutely nothing to do with efficiency. They are a full-on assault on science. Trump and Musk want to kill it. Universities who have been silent for fear of losing funds: how’s that working for you? It’s time to fight back.
