Supercritical Fluid Chromatography

Science, 1983
Chromatographic separations with a supercritical fluid as the mobile phase were suggested more than 20 years ago. Availability of commercial hardware makes this technique more widely usable today. Many separations by this method are now carried out with supercritical carbon dioxide as the mobile phase and packed liquid-chromatography ...

Decoding Proton‐Coupled Electron Transfer Mechanism of Nicotine for Multi‐Scenario Portable Electrochemical Sensing

Advanced Science, EarlyView.
A key challenge in nicotine electroanalysis is the unresolved complexity of its interface process, which directly determines sensor metrics. Herein, the proton‐coupled electron transfer mechanism of nicotine is decoded for multi‐scenario portable electrochemical sensing.

Exploring the World of Double Nanohoops

Angewandte Chemie International Edition, EarlyView.
As two conjugated nanohoops covalently linked by a central unit, double nanohoops are a relatively new class of strained nanocarbons with different properties to single nanohoops. This review gives an overview of all reported double nanohoops, categorizing their structures, syntheses, and discussing properties and applications. Creativity and synthetic

Supercritical Fluid Chromatography

International Journal of Advanced Research in Science, Communication and Technology, 2023
History of Supercritical Fluid Chromatography In 1822, the French physicist Charles Cannard de La Tour placed a liquid and a flint ball in a Papin rifle pressure vessel and heated the liquid with a sealed cannon. 1) When the container was shaken, the bullet broke through the air-liquid interface, and the sound of the bullet scattering was heard.

Unlocking the Potential of Electrolyte Recovery from Battery Waste: A Promising Path to Sustainable and Safe Li‐Ion Batteries

Batteries &Supercaps, EarlyView.
Due to several challenges, electrolyte recovery from spent battery waste has been less explored compared to electrode materials. This study presents various strategies for recovering electrolytes from spent battery waste. Electrolyte recovery can prevent hazardous chemicals from being released into the environment.

Synthetic Cathepsin B Sensitive Adjuvant‐Peptide Conjugates to Target Intracellular Toll‐Like Receptors 7 and 8

ChemistryEurope, EarlyView.
Cathepsin B‐sensitive peptide–adjuvant conjugates are designed, synthesized, and evaluated to deliver an antigenic peptid and an adjuvant targeting Toll‐like receptors 7 and 8 (TLR7/8) to antigen presenting cells. The adjuvant is released by cathepsin B resulting in antigen presentation and TLR mediated T cell activation.
