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

Affinity Chromatography: Principles and Applications
, 2012 Since the inception of affinity chromatography 50 years ago (Cuatrecasas et al, 1968), traditional purification techniques based on pH, ionic strength, or temperature have been replaced by this sophisticated approach.

Ternary Synergy in Layered Double Hydroxides for Efficient and Stable Nitrate Reduction
Advanced Functional Materials, EarlyView.Ternary CuZnFe LDH enables efficient electrocatalytic nitrate‐to‐ammonia conversion via controlled in situ reconstruction: zinc leaching creates porous active sites, copper reduced to metallic copper, while iron oxide keeps stable. Synergistic Cu‐Fe redox coupling drives tandem catalysis (nitrate→nitrite→NH3), achieving 95% Faraday efficiency and ...

Modulating weak protein-protein cross-interactions by addition of free amino acids at millimolar concentrations [PDF]
arXivIn this paper, we quantify weak protein protein interactions in solution using Cross-Interaction Chromatography (CIC) and Surface Plasmon Resonance (SPR) and demonstrate that they can be modulated by the addition of free amino acids. With CIC, we determined the second osmotic virial cross-interaction coefficient (B23) as a proxy for the interaction ...

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.Glepaglutide (GL), a GLP‐2 analog with an extended half‐life (50 h), is currently undergoing clinical trials for patients with short bowel syndrome. GL requires subcutaneous injection, which poses challenges for potential patient compliance. To address this challenge, we loaded GL into a rectal foam formulation using CO2 as a permeation enhancer to ...
