Aggregation of Gramicidin A in Phospholipid Langmuir–Blodgett Monolayers [PDF]

Biophysical Journal, 2002
The aggregation of Gramicidin A (gA) in dipalmitoylphosphatidylcoline (DPPC) monolayers is investigated by both thermodynamic and structural methods. Compression isotherm analysis and atomic force microscopy (AFM) observations are performed. Our experimental results indicate that gA aggregation does occur in DPPC monolayers even at very low gA ...

Ilexoside K Ameliorates Atherosclerosis by Suppressing CD72hi Macrophages and Blocking CXCL12–CXCR4 Axis to Inhibit Endothelial Pyroptosis

Advanced Science, EarlyView.
CD72hi macrophages drive endothelial pyroptosis and accelerate atherosclerosis through CXCL12–CXCR4‐mediated immune–vascular crosstalk. Ilexoside K suppresses this pathogenic communication by modulating CXCR4‐dependent endothelial responses, reducing inflammation and plaque progression. These findings reveal a macrophage–endothelial regulatory axis and

Nonequilibrium Bubbles in a Flowing Langmuir Monolayer

, 2016
We investigate the nonequilibrium behavior of two-dimensional gas bubbles in Langmuir monolayers. A cavitation bubble is induced in liquid expanded phase by locally heating a Langmuir monolayer with an IR-laser.

Free Charge Generation in Organic Photoconversion Devices–the Impact of Electrostatic Potentials

Advanced Energy Materials, EarlyView.
Free charge generation in organic photovoltaic and photodetector devices typically requires an external driving force to separate bound excitons formed upon photoexcitation. This review details how electrostatic potentials, arising from molecular charge distributions in organic semiconductors, can impact interfacial energetic landscapes and promote ...

Study of the Adsorption Thermodynamics and Kinetics of Lipoic Acid onto Three Types of Resin

Adsorption Science & Technology, 2004
The adsorption of lipoic acid on three different types of resin was compared. Studies of the adsorption thermodynamics and kinetics of lipoic acid onto XAD-4, NDA-100 and ND-90 resins were carried out via static experiments.

Accelerating Biosensor Discovery: A Computationally‐Driven Pipeline for Microplastics Monitoring

Advanced Intelligent Discovery, EarlyView.
A computationally guided pipeline unites molecular simulation, synthetic biology, electrochemical engineering, and machine learning to accelerate biosensor discovery. A Bacillus anthracis carbohydrate‐binding module is used to develop a high‐performance micro‐ and nanoplastics sensor with greatly reduced error and variability.

Two‐Dimensional Frameworks From Metal Oxo Clusters at Liquid Interfaces

Small Structures
We report the realization of a two‐dimensional analog of the archetypical metal‐organic framework UiO‐66 as a Langmuir monolayer, constructed from preformed metal oxo clusters and amphiphilic terephthalic acid ligands at the air–water interface ...

Experimental Technique to Study the Interaction Between a Bubble and the Particle-Laden Interface

Frontiers in Chemistry, 2018
An experimental apparatus was developed based on the Langmuir-Blodgett trough design to investigate the compression of monolayers of micron size spherical glass particles at the air-water interface and the interaction of an air bubble with the monolayers.

Design and Performance of a High‐Efficiency Inhibitor: Synergistic Effect of Modified Chitosan and Boron Nitride Nanosheets on Steel Protection

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Metal corrosion causes significant economic losses and safety hazards, underscoring the urgent need for effective, environmentally friendly corrosion inhibitors. In this study, an organic–inorganic composite inhibitor, chitosan–glucose–BN (CS–GL–BN) was developed to protect Q235 mild steel in a 3.5‐wt% NaCl solution.
