Empowering Machines to Think Like Chemists: Unveiling Molecular Structure-Polarity Relationships with Hierarchical Symbolic Regression [PDF]

open access: yesarXiv
Thin-layer chromatography (TLC) is a crucial technique in molecular polarity analysis. Despite its importance, the interpretability of predictive models for TLC, especially those driven by artificial intelligence, remains a challenge. Current approaches, utilizing either high-dimensional molecular fingerprints or domain-knowledge-driven feature ...

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Kinetic formulation of a 2 $\times$ 2 hyperbolic system arising in gas chromatography [PDF]

open access: yesarXiv, 2017
The PSA system commonly used in the context of gas-solid chromatography is reformulated as a single kinetic equation using an additional kinetic variable. A kinetic numerical scheme is built from this new formulation and its behavior is tested on solving the Riemann problem in different configurations leading to single or composite waves.

Diffusion Coefficient Estimations by Thin-Channel Column Inverse Gas Chromatography : Preliminary Experiments [PDF]

open access: yes, 2000
A thin-channel gas chromatography column was designed and used to measure diffusion coefficients of water and iso propanol in polymer phase via inverse gas chromatography (ICC) technique.

Supramolecular Conductive Hydrogels With Homogeneous Ionic and Electronic Transport

open access: yesAdvanced Materials, EarlyView.
Poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) based conductive hydrogels have received great attention in bioelectronics on account of their tissue‐like mechanical properties. However, inhomogeneous morphologies of the conducting PEDOT phase limits their electrical and mechanical properties. Here, supramolecular hydrogels with self‐

Free amino acids in a cave beetle \u3cem\u3eDarlingtonea kentuckensis\u3c/em\u3e Valentine (Coleoptera: Carabidae) [PDF]

open access: yes, 1974
Free amino acids of Darlingtonea kentuckensis were investigated by two-dimensional, thin-layer chromatography on Silica Gel G. Thirteen amino acids which could be identifìed (alanine, glutamic acid, glycine, histidine, isoleucine and/or leucine, lysine ...

Protein‐Like Polymers Targeting Keap1/Nrf2 as Therapeutics for Myocardial Infarction

open access: yesAdvanced Materials, EarlyView.
We describe a Keap1 targeting protein‐like polymer (PLP) which activates Nrf2, an important cytoprotective transcription factor for relieving myocardial infarction‐induced oxidative stress. This PLP increases cell survival in vitro in multiple relevant cardiac cell types and elicits pro‐reparative responses, improving cardiac function in a preclinical ...

Mars Spectrometry 2: Gas Chromatography -- Second place solution [PDF]

open access: yesarXiv
The Mars Spectrometry 2: Gas Chromatography challenge was sponsored by NASA and run on the DrivenData competition platform in 2022. This report describes the solution which achieved the second-best score on the competition's test dataset. The solution utilized two-dimensional, image-like representations of the competition's chromatography data samples.
