Iron acquisition with the natural siderophore enantiomers pyochelin and enantio-pyochelin in Pseudomonas species [PDF]

open access: yes, 2018
The bacterial siderophore pyochelin is composed of salicylate and two cysteine-derived heterocycles, the second of which is modified by reduction and N-methylation during biosynthesis. In Pseudomonas aeruginosa, the first cysteine residue is converted to

Design and Thermodynamic Analysis of the Next‐Generation Gas Turbine‐Transcritical CO2‐Combined Cycle

open access: yesInternational Journal of Energy Research, Volume 2025, Issue 1, 2025.
The development of high‐efficiency, low‐pollution, zero‐emission, flexible‐fuel, and low‐cost gas turbine (GT) generator sets is a crucial strategy to achieve carbon peaking and carbon neutrality goals. This research utilizes the reheat GT cycle (RGTC) as the top cycle and constructs four RGTC‐supercritical/transcritical carbon dioxide (s/tCO2 ...

Rationally Designed Functionalization of Single‐Walled Carbon Nanotubes for Real‐Time Monitoring of Cholinesterase Activity and Inhibition in Plasma

open access: yesSmall, Volume 20, Issue 24, June 12, 2024.
Cholinesterase (CHE) activity is monitored in buffer and blood plasma using NIR fluorescent SWCNTs as probes. The SWCNTs are rationally functionalized with myristoylcholine (MC), a substrate of CHE, which, upon undergoing hydrolysis by CHE, leads to a decrease in the fluorescence intensity of SWCNTs.

Demonstration of a small‐scale power generator using supercritical CO2

open access: yesCarbon Energy, Volume 6, Issue 4, April 2024.
In response to climate change, the supercritical CO2 (sCO2) power cycle has been studied worldwide and considered the next generation of power generation technology. Most of the study is focused on theoretical analysis, and the experimental investigation of a CO2 power cycle is insufficient. In addition, the power capacity is usually between 0.1 and 10
