Abstract

Crystal growth in colloidal particle monolayers fabricated by Langmuir-Blodgett method on 4 in. sapphire wafers was investigated under the condition of two techniques, that is, ultrasonic annealing at 1.2 to 1.5 MHz and barrier-sway process at 0.2 to 0.5 Hz. Significant increases of the ordered area were obtained by the both techniques and more than 60 times growth was confirmed. The remaining crystal defects after the growth were categorized as grain boundary, vacancy, and line defect. Both techniques exhibited different features regarding the component ratio of the defects, and different mechanisms for the reorientation of particles are discussed. The driving force of these reorientations is thought to be associated with the 2D Ostwald ripening of colloidal crystals.

Air/Water Interfacial Monolayer Assembly of Peptide-Conjugated Liquid-Crystalline Molecules

Rie Makiura, Anna Niwa, Hiroki Eimura, Junya Uchida, Takashi Kato

Summary: The research investigates the self-assembling behavior of two types of amphiphilic mesogens with different peptide chains at air/water interfaces. It is found that the bioconjugated molecules are in a liquid expanded state with a curved molecular arrangement at the interface, leading to changes in water contact angles on the substrate surface with monolayers.

On the Propensity of Excess Hydroxide Ions at the Alcohol Monolayer-Water Interface

Dibyendu Bandyopadhyay, Kalyan Bhanja, Niharendu Choudhury

Summary: Atomistic molecular dynamics simulations were used to investigate the distribution of self-ions (H+ and OH-) at the interface between a long-chain C16-OH alcohol monolayer and water. Contrary to the air-water interface, the hydroxide ion (OH-) was found to accumulate at the alcohol monolayer-water interface instead of the hydronium ion (H3O+). The OH- ions were stabilized at the interface due to favorable interactions with the alcoholic -OH groups, while the H3O+ ions did not show such stabilization. The coordination numbers of the self-ions indicated that around 50% of water neighbors were replaced by alcoholic -OH in the case of hydroxide ions, compared to only 15% for hydronium ions. Interestingly, the hydroxide ion acted as the H-bond acceptor, while the hydronium ion acted as the H-bond donor.

Quantitative Evaluation on the Degradation Process of the Pulmonary Surfactant Monolayer When Exposed to Low-Level Ozone of Ambient Environment

Lin Qao, Zhen Chen, Chunji Takada, Hitoshi Chiba, Ken-ichi Inoue, Shu-Ping Hui, Shen Ye

Summary: In this study, we investigated the degradation process of a major component of pulmonary surfactant (PS), 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC), exposed to low-level ambient ozone. We found that low-level ozone can readily degrade POPC molecules and induce oxidation damage to unsaturated lipids, triggering lung inflammation.

Breaking and Making of Water Structure at the Air/Water-Electrolyte (NaXO3; X = Cl, Br, I) Interface

Subhadip Roy, Jahur Alam Mondal

Summary: Research shows that ions have a strong correlation with the structure of hydrogen bonding at the air/water interface and in bulk water. Specifically, structure-breaking anions decrease hydrogen bonding at the interface, while structure-making anions have the opposite effect. None of the electrolytes studied significantly affect the orientation of water molecules at the interface.

Fabrication of flexible conductive nanosheets at air-water interface by UV irradiation of loosely-packed AgNPs monolayer

Fuyuki Nakagawa, Ryota Kichijo, Mizuki Matsukawa, Ke-Hsuan Wang, Yoshiro Imura, Takeshi Kawai

Summary: We have demonstrated a UV irradiation method to synthesize conductive silver nanosheets from monolayers of silver nanoparticles (AgNPs). The process involves the decomposition of a cationic water-insoluble surfactant under UV irradiation, which promotes sintering between AgNPs and converts their surfaces into conductive nanosheets. Additionally, AgNPs from the surrounding area infiltrate the UV-irradiated region, allowing the fabrication of nanosheets with loosely packed, low-density structures and numerous voids.

Sunflower Proteins at Air-Water and Oil-Water Interfaces

Alexandre Poirier, Antonio Stocco, Romain Kapel, Martin In, Laurence Ramos, Amelie Banc

Summary: The study investigated the adsorption process of sunflower protein extract at two air-water and oil-water interfaces, revealing a three-step mechanism. Initially, a diffusion-limited adsorption of proteins at interfaces occurs, followed by the formation of a three-dimensional saturated monolayer of proteins, and finally a thick layer expanding in the aqueous phase. The study also found that the adsorption mechanisms of proteins exhibit significant divergences at longer adsorption times.

Significantly Accelerated Photochemical Perfluorooctanoic Acid Decomposition at the Air-Water Interface of Microdroplets

Kejian Li, Wenbo You, Wei Wang, Kedong Gong, Yangyang Liu, Longqian Wang, Qiuyue Ge, Xuejun Ruan, Jianpeng Ao, Minbiao Ji, Liwu Zhang

Summary: This study demonstrates that the photodecomposition of perfluorooctanoic acid (PFOA) can be significantly accelerated by carrying out the process in microdroplets. The abundance of the air-water interface in microdroplets promotes the decomposition of PFOA, resulting in higher removal rates. The method shows high performance and universality in actual water matrices.

Emergence of Electric Fields at the Water-C12E6 Surfactant Interface

Rahul Gera, Huib J. Bakker, Ricardo Franklin-Mergarejo, Uriel N. Morzan, Gabriele Falciani, Luca Bergamasco, Jan Versluis, Indraneel Sen, Silvia Dante, Eliodoro Chiavazzo, Ali A. Hassanali

Summary: This study investigates the properties of the water and surfactant C12E6 interface, finding that the addition of C12E6 near the critical micelle concentration enhances hydrogen bond strength and alters the orientation of water molecules. This leads to the formation of a broad interface with a large electric field, potentially opening up new possibilities for designing catalytic and light-harvesting systems at the water-surfactant-air interface.

Interactions between a responsive microgel monolayer and a rigid colloid: from soft to hard interfaces

Steffen Bochenek, Cathy E. McNamee, Michael Kappl, Hans-Juergen Butt, Walter Richtering

Summary: Responsive poly-N-isopropylacrylamide-based microgels are commonly used as model colloids with soft repulsive interactions. The interaction between microgel monolayers at the air-water interface and a hard colloid in the water is influenced by temperature and lateral compression. Temperature and lateral compression affect the stiffness and adhesion of the monolayer, while the temperature-dependent swelling of the microgel fractions in the aqueous phase strongly influences the interaction with the probe.

Spontaneous dark formation of OH radicals at the interface of aqueous atmospheric droplets

Kangwei Li, Yunlong Guo, Sergey A. Nizkorodov, Yinon Rudich, Maria Angelaki, Xinke Wang, Taicheng An, Sebastien Perrier, Christian George

Summary: Hydroxyl radicals (OH) play a crucial role as oxidants in atmospheric chemistry, and their aqueous sources have been mainly attributed to known bulk processes or interfacial chemistry driven by O3 and NO3 radicals. This study provides experimental evidence that OH radicals can be spontaneously produced at the air-water interface of aqueous droplets, even in the absence of known precursors, possibly due to the strong electric field formed at such interfaces. The measured OH production rates in atmospherically relevant droplets are comparable to or higher than those from known bulk sources, particularly in the dark. As aqueous droplets are widespread in the troposphere, this interfacial source of OH radicals is expected to have significant impacts on atmospheric multiphase oxidation chemistry, with implications for air quality, climate, and health.
