Multiscale X-ray scattering elucidates activation and deactivation of oxide-derived copper electrocatalysts for CO reduction.

Electrochemical reduction of carbon dioxide (CO) into sustainable fuels and base chemicals requires precise control over and understanding of activity, selectivity and stability descriptors of the electrocatalyst under operation. Identification of the active phase under working conditions, but also deactivation factors after prolonged operation, are of the utmost importance to further improve electrocatalysts for electrochemical CO conversion. Here, we present a multiscale in situ investigation of activation and deactivation pathways of oxide-derived copper electrocatalysts under CO reduction conditions.

Can Language Models Trained on Written Monologue Learn to Predict Spoken Dialogue?

Transformer-based Large Language Models (LLMs) have recently increased in popularity, in part due to their impressive performance on a number of language tasks. While LLMs can produce human-like writing, the extent to which these models can learn to predict spoken language in natural interaction remains unclear. This is a nontrivial question, as spoken and written language differ in syntax, pragmatics, and norms that interlocutors follow.

Periodic Paralysis in a Child With Thermosensitive Mitochondrial Trifunctional Protein Deficiency.

Mitochondrial trifunctional protein (MTP) deficiency is a fatty acid oxidation disorder associated with a spectrum of phenotypes. Patients with high residual enzyme activity tend to have milder phenotypes, and recently, fever-induced episodic myopathy was reported in association with a thermosensitive form of MTP deficiency. We report a 10-year-old male with recurrent episodes of acute flaccid paralysis involving upper and lower extremities in association with bulbar muscle weakness in the context of febrile illness, a phenotype reminiscent of recurrent periodic paralysis.

Interrogation of Oxidative Pulsed Methods for the Stabilization of Copper Electrodes for CO Electrolysis.

Using copper (Cu) as an electrocatalyst uniquely produces multicarbon products (C-products) during the CO reduction reaction (CO2RR). However, the CO2RR stability of Cu is presently 3 orders of magnitude shorter than required for commercial operation. One means of substantially increasing Cu catalyst lifetimes is through periodic oxidative processes, such as cathodic-anodic pulsing.
