Abstract:
Abstract Monolayer Technique, Nonionic Detergent, Erythrocyte Shape The degree and time-course of expansion of palmitoyloleoylphosphatidylcholine (PC) and bovine brain phosphatidylserine (PS)/PC (75:25, mol/mol) monolayers at 32 mN/m caused by differently charged amphiphiles (detergents) added to the sub-phase buffer (pH 7.4, 22 °C) were followed. Amphiphiles were added to the sub-phase at a concentration/monolayer area corresponding to the concentration/erythrocytes surface area where sphero-echinocytic or sphero-stomatocytic shapes are induced (0.46-14.6 μᴍ). Nonionic, cationic and anionic am­ phiphiles expanded the PS/PC monolayer significantly more (1.7-4.2 times) than the PC monolayer. A zwitterionic amphiphile expanded both monolayers to a similar extent. The initial rate of monolayer-expansion was higher for all amphiphiles (1.7-20.4 times) in the PS/PC monolayer than in the PC monolayer.It is suggested that hydrophobic interactions govern the intercalation of amphiphiles into monolayers, and that monolayer packing, modulated by phospholipid head group interactions and alkyl chain saturation, strongly influence amphiphile intercalation. A possible relation between the monolayer-expanding effect of amphiphiles and their effect on erythrocyte shape is discussed.

Abstract:
Controlled crystallization of BaF2 under two different kinds of monolayers, octadecylamine [CH3(CH2)17NH2] and hexadecanol [CH3(CH2)14CH2OH], has been studied by using x-ray diffraction (XRD) and scanning electron microscope. It was found that the monolayer headgroup, the degree of ionization of the headgroup, etc., had a complicated effect on the selectivity of monolayers for crystal and on the morphology and orientation of crystals grown under the compressed monolayers. At pH = 7.0, XRD analysis showed that (100)-oriented BaF2 crystals were formed under the octadecylamine monolayer, while several kinds of crystals were found under the hexadecanol monolayer. In comparison, at pH = 8.5, both (100)-oriented BaF2 and (111)-oriented Ba(NO3)2 crystals were obtained under the monolayer of octadecylamine. However, crystals formed under hexadecanol monolayer consist of BaF2, Ba(NO3)2, etc. The detailed mechanism for crystallization was discussed in terms of the specific interaction and lattice matching between the monolayer headgroup and the nucleating species.

Abstract:
Abstract In this paper, GeSe2 thin film and glass ingot were prepared in a layered structure. Subsequently, the 2D amorphous monolayers were achieved from layered thin film and layered glass ingot. The thicknesses of monolayers from thin film range from 1.5 nm to 5 nm. And the thickness of monolayer from glass ingot is 7 μm. The fast cooling of material results in the formation of self-assembled monolayers. In the case of thin film, layers are connected with “bridge”. After doping of Ag, the precipitation of nano particles exfoliates the adjacent monolayers which can be further dispersed by etching of Ag particles. In the case of glass ingot, the composition changes at 1 % between adjacent monolayers, according to EDX (energy-dispersive X-ray spectroscopy) spectra. And the glass 2D monolayer can be mechanically peeled off from the glass ingot.

Full text
Abstract:
Simple devices that contain alkanethiolate monolayers sandwiched between conducting films were prepared by fixing a gold film to the surface of an alkanethiolate monolayer (on a gold substrate) with silver paint. These devices, and similar devices that did not contain alkanethiolate monolayers, were tested as resistors in d.c . circuits. The devices that contained octadecanethiolate monolayers had resistances of approximately 1012 Ω, 10 orders of magnitude higher than the resistance of devices that contained no monolayers. Sulfur- terminated alkanethiolate monolayers were prepared by treatment of carboxylic acid-terminated monolayers with vapours of thionyl chloride followed by vapours of hexane-1,6-dithiol. Attempts to use the sulfur-containing groups at the surface of this monolayer as 'molecular glue' to attach a flexible gold film to the surface of the monolayer were unsuccessful.

Abstract:
Langmuir-Blodgett (LB) films have been applied to molecular electronics, nonlinear optics, and biosensors. Their useful properties can be accessed by using a defect-free monolayer—the precursor of LB films. In order to prepare a defect-free or defect-diminished monolayer, it is necessary to estimate the molecular arrangements and structural defects in the monolayer. The actual structure of monolayers on the surface of water have been proposed on the basis of recent morphological and structural studies. Molecular-aggregation processes or monolayer-formation processes do not always match the general concept concluded from surface pressure-area (π-A) isotherms. Therefore, a universal understanding has not been reached. Here we present a novel and systematic classification for the aggregation structure of monolayers on the water surface and also demonstrate how to prepare defect-diminished monolayers.

Abstract:
Caco-2 monolayers are a common in vitro model used to evaluate human intestinal absorption. The reference protocol requires 21 days post-seeding to establish a stable and confluent cell monolayer, which is used in a single permeability assay during the period of monolayer stability (up to day 30). In this work, we characterize variations in the tightness of the cell monolayer over the stable time interval and evaluate the conditions required for their re-use in permeability assays. The monolayer integrity was assessed through TEER measurements and permeability of the paracellular marker Lucifer Yellow (LY), complemented with nuclei and ZO-1 staining for morphological studies and the presence of tight junctions. Over 150 permeability assays were performed, which showed that manipulation of the cell monolayer in the permeability assay may contribute significantly to the flux of LY, leading to Papp values that are dependent on the sampling duration. The assay also leads to a small decrease in the cell monolayer TEER, which is fully recovered when cell monolayers are incubated with culture media for two full days. When this procedure is followed, the cell monolayers may be used for permeability assays on days 22, 25, and 28, triplicating the throughput of this important assay.

Abstract:
Monolayers are highly desirable for their evaporation reducing capabilities due to their relatively minimal cost and ease of application. Despite these positive attributes, monolayers have consistently failed to perform effectively due to the harsh wind and wave conditions prevalent across real-world water reserves. An exhaustive and consistent study testing the influence of wind and wave combinations on monolayer performance has yet to be presented in the literature. To remedy this, the effect of simultaneous wind and wave conditions on a benchmark high-performance monolayer (octadecanol suspension, CH3(CH2)16CH2OH) has been analysed. Subjected only to waves, the monolayer remained intact due to its innate ability to compress and expand. However, the constant simultaneous application of wind and waves caused the monolayer to break up and gather down-wind where it volatilised over time. At wind speeds above 1.3 m s−1 the monolayer was completely ineffective. For wind speeds below this threshold, the monolayer had an influence on the evaporation rate dependent on wind speed. From these results a series of application protocols can now be developed for the optimised deployment of monolayers in real-world water reserves. This will be of interest to private, commercial and government organisations involved in the storage and management of water resources.

Abstract:
We report the interaction between gas molecules (NO2 and NH3) and the SnSe2 monolayers with vacancy and dopants (O and N) for potential applications as gas sensors. Compared with the gas molecular adsorbed on pristine SnSe2 monolayer, the Se-vacancy SnSe2 monolayer obviously enhances sensitivity to NO2 adsorption. The O-doped SnSe2 monolayer shows similar sensitivity to the pristine SnSe2 monolayer when adsorbing NO2 molecule. However, only the N-doped SnSe2 monolayer represents a visible enhancement for NO2 and NH3 adsorption. This work reveals that the selectivity and sensitivity of SnSe2-based gas sensors could be improved by introducing the vacancy or dopants.

Abstract:
Rat alveolar type II cells were cultured on collagen-coated filters (CCF) and human amnionic basement membrane (ABM) to determine the effect of culture substratum on the development of monolayer bioelectric properties. Monolayers cultured on both substrata rapidly developed bioelectric properties with similar time courses, monolayer capacitance values (approximately 1 muF/cm2), current-voltage relationships, and responses to stimulants and inhibitors of active ion transport. Increasing seeding densities tended to increase monolayer bioelectric properties regardless of culture substratum. Monolayers cultured on ABM had higher resistance values (491 vs. 291 omega.cm2) and lower short-circuit currents (2.85 vs. 4.51 muA/cm2) than monolayers with similar cell densities cultured on CCF. These differences in monolayer bioelectric properties were not due to differences in substratum resistance or capacitance effects. The relationships between monolayer bioelectric properties were also affected by the culture substratum. In additional experiments, cells cultured on contracted gels formed monolayers with high short-circuit currents (9.25 muA/cm2). Cell morphology varied depending on the culture substratum, with cells cultured on contracted gels appearing the most cuboidal, whereas the flattest and most attenuated cells were those cultured on ABM. On the basis of these observations, we conclude that culture substratum significantly affects the development of bioelectric properties across alveolar type II cell monolayers. In vivo the bioelectric properties across the alveolar epithelium may also vary with changes in cellular substratum or cell density (e.g., after acute lung injury) and possibly with cell morphology (e.g., alveolar type I vs. alveolar type II cells).

Abstract:
Il ditellurio di tungsteno (WTe2) appartiene alla classe dei dicalcogenuri di metalli di transizione (TMDs), che rappresentano attualmente i materiali più promettenti, insieme al grafene, nel campo di ricerca dei cristalli bidimensionali (2D). Grazie ad una caratteristica struttura stratificata, con differenti piani atomici legati da forze di van der Waals, mediante esfoliazione è possibile isolare strati di spessore quasi-atomico di TMDs, detti “monostrati”, con proprietà spesso molto diverse dal materiale bulk originario. Il WTe2 nella sua forma a monostrato, è stato recentemente oggetto di interesse scientifico, in quanto teoricamente predetto essere un isolante topologico (TI) bidimensionale. Un TI è un materiale che internamente si comporta come un isolante elettrico ma che sulla superficie manifesta stati conduttivi. Lo scopo di questa tesi è studiare le proprietà si trasporto di monostrati di WTe2 in micro-dispositivi realizzati con opportune tecniche di nanofabbricazione. L'ossidazione della superficie esterna del WTe2, dovuta ad una non-perfetta stabilità in aria, influenza significativamente il trasporto elettronico in cristalli costituiti da pochi strati atomici ed è causa di una transizione metallo-isolante. Una possibile soluzione per evitare la degradazione del materiale consiste nell' “incapsulamento” di un monostrato di WTe2 fra materiali 2D chimicamente inerti, come il nitruro di boro esagonale. A tale proposito, si è sviluppata una tecnica di “trasferimento” che permette di sollevare e allineare con precisione micrometrica strati di spessore atomico di differenti materiali, assemblando eterostrutture di van der Waals. Campioni selezionati sono studiati mediante misure di magneto-transporto a bassa temperatura (fino a 0.250 K). I dati analizzati evidenziano l'esistenza di un gap di energia in monostrati di WTe2 e la presenza di una corrente localizzata ai bordi del sistema, coerentemente con l'ipotesi di un isolante topologico 2D.

Abstract:
Organic molecules adsorbed on inorganic substrates are the topics of interest in this thesis. Interfaces of this kind are found in dye sensitized solar cells that convert solar energy to electricity, a promising environmentally friendly energy source which might provide a route to replace fossil fuels. Another field where these interfaces play a role is in molecular electronics, an approach to solve the down scaling in the ever increasing hunt for miniaturized electronic devices. The motivation for this work lies among other in these applications and surface science is a suitable approach to investigate the electronic and morphologic properties of the interfaces as it provides detailed knowledge on an atomic level. Phthalocyanines are the organic molecules investigated and the inorganic substrates range from wide band gap via narrow band gap semiconductors to metals. Photoelectron and X-ray spectroscopy experiments are performed to shed light on the electronic properties of the adsorbed molecules and the substrate, as well as the chemical interaction between adsorbate and substrate at the interface. The ordering of the adsorbate at the interface is important as ordered molecular thin films may have other properties than amorphous films due to the anisotropic electronic properties of the organic molecules; this is investigated using scanning tunneling microscopy. We find that the phthalocyanines are affected by adsorption when the substrate is TiO2 or Ag, where charge transfer from the molecule occurs or an interface state is formed respectively. The molecules are adsorbed flat on these surfaces giving a large contact area and a relatively strong bond. On Ag, ordered structures appear with different symmetry depending on initial coverage. The reactivity of the TiO2 surface is not ideal in the solar cell application and by modifying the surface with a thin organic layer, the negative influence on the adsorbed phthalocyanine is reduced. ZnO is not as reactive as TiO2, thanks maybe to the upright adsorption mode of the phthalocyanines. The semiconductor InSb is less reactive leading to self-assembled molecular structures on the (001) surface, either homogenously distributed in a one monolayer thick film or in strands along the reconstruction rows. InAs on the other hand has a larger influence on the adsorbed molecules resulting in a metallic film upon thermal treatment.

Abstract:
Endozytose erfordert hohe Membrankrümmung und führt zu Flächenänderungen der Membranhälften. Dies kann durch eine Oberflächendifferenz zwischen den Schichten initiiert werden, die durch geänderte Lipidzusammensetzungen hervorgerufen werden kann. Daher wurde die Hypothese aufgestellt, dass Lipid-Transporter zu Beginn der Endozytose für veränderte Flächenverhältnisse verantwortlich sind. Um den Einfluss veränderter Flächen auf Endozytose zu untersuchen, wurden die Oberflächenverhältnisse der Membran durch Zugabe von Phospholipiden verändert und anschließend Endozytose gemessen. Abhängig von der Sorte wurden die Lipide nur in die äußere Schicht eingebaut oder auch auf die innere Seite transportiert, wodurch die entsprechende Seite vergrößert wurde. Die Zugabe verschiedener Aminophospholipide, die auf die innere Membranseite transportiert werden, führte zu gesteigerter „bulk flow“ Endocytose in K562-Zellen. Darüber hinaus deuten die Ergebnisse darauf hin, dass Clathrin-vermittelte Endozytose von Hep2-Zellen ebenfalls stimuliert wurde. Umgekehrt hatte die Zugabe von Lipiden, die auf der äußeren Hälfte bleiben, reduzierte „bulk flow“- oder Clathrin-vermittelte Endozytose in verschiedenen Zelllinien zur Folge. Bemerkenswert ist, dass auch Clathrin-vermittelte Endozytose durch die Lipidzugabe beeinflusst wurde, obwohl gerade in diesem Weg viele Proteine involviert sind, die Krümmung induzieren können. Dies passt zu einem neuen Modell wie Lipidtransporter in Endozytose involviert sind. Durch den Transport von Lipiden und die zusätzliche Interaktion mit Endozytoseproteinen, könnten diese Transporter zwei Mechanismen zur Erzeugung von Krümmung miteinander verbinden: Membrankrümmung induziert durch eine Flächenasymmetrie zwischen den Membranhälften und durch Wechselwirkung mit Proteinen. Die Ergebnisse dieser Arbeit deuten darauf hin, dass die für Endozytose notwendige Krümmung durch die durch Lipidtransport induzierte Flächenasymmetrie der Membranschichten unterstützt wird.
Endocytic engulfment requires high local membrane curvature and causes significant area changes of the membrane leaflets. This can be initiated by differences between the surface areas of the two monolayers related to leaflet specific modulation of lipid composition. Thus, it was proposed that lipid translocators, pumping phospholipids from the outer to the inner leaflet, account for monolayer area asymmetry as an early step in endocytosis. To elucidate the influence of this asymmetry on endocytosis, surface area relation was altered by adding exogenous phospholipids to living cells and changes in endocytic activity were quantified. Depending on the lipid species, exogenous lipids were only incorporated into the outer layer or subsequently translocated across the plasma membrane thereby increasing either the outer or inner surface area. Addition of different analogues of aminophospholipids, which are translocated to the inner leaflet, led to an enhancement of bulk flow endocytosis in K562 cells. Moreover, our data indicate that clathrin-mediated endocytosis of Hep2 cells was stimulated as well. Inversely, addition of phospholipids, which remain on the outer layer, reduced bulk flow or clathrin-mediated endocytosis in various cell lines. Notably, also clathrin-mediated endocytosis was influenced by the addition of lipids, although many proteins noted for their ability to induce membrane curvature are known to be implicated in this pathway. This corroborates a recent model how aminophospholipid translocases are implicated in endocytosis. Upon translocating lipids and additionally interacting with endocytic accessory proteins, lipid translocators could integrate two processes to generate curvature: membrane bending based on monolayer area asymmetry and protein-related mechanisms. Collectively, findings in the present study suggest that curvature generation in endocytosis is supported by the induction of monolayer area asymmetry mediated by the translocation of lipids.

Abstract:
Molecular self-assembly has recently attracted significant attention for possible application in organic electronic and optoelectronic devices, such as self-assembled monolayer field-effect transistors (SAMFETs) and functional self-assembled integrated circuits. Self-assembly combines the advantages of low temperature solution processability, regio-selective monolayer adsorption and nano-scale control of film thickness. Much progress has been made in improving device performance using self-assembled monolayers (SAMs). However, most SAMFET devices reported to date showed current modulation only with submicrometre channels, with low device yields and poor reproducibility as a result of limited lateral interconnection of the semiconducting layer.In an attempt to address these issues, this thesis presents an investigation of the synthesis and properties of conjugated SAM molecules for use as the charge transporting layer in SAMFETs. Chapter 1 gives a comprehensive introduction to SAM-based surface systems, organic semiconductors and their use in OFETs and SAMFETs. Chapter 2 discusses attempts to design and synthesise p-type conjugated molecules capable of self-assembly on oxide surfaces based on a phenylene-bithiophene semiconducting core. The optical and electrochemical properties, as well as the thermal behaviour of these molecules are studied in detail. This theme is carried over to Chapter 3, which describes the synthesis, chemical and physical characterisation of two families of n-type SAM molecules. These molecules consist of NTCDI cores with hexyl or cyclohexyl chains as end-capping groups. Incorporation of a selection of materials as the active layer in OFETs or SAMFETs to evaluate the charge transport is demonstrated in Chapter 4. Monolayer films based on p-type monochlorosilane-terminated SAM molecules are made using the solution assembly technique and characterised by contact angle and AFM. OFETs made from DH-PTTP by both thermal evaporation and spin coating show high mobilities comparable to the best values reported in the literature. Top-contact SAMFETs show a hole mobility of 1.1 × 10-3 cm2V-1s-1 in air, consistent with those of solution processed DH-PTTP based OFETs. Finally, an overview of the project and some suggestions for future work are presented in Chapter 5.

Full text
Abstract:
The aim of this work has been to make use of surface scattering techniques to study soft matter at interfaces. The work presented herein is composed of two distinct bodies of work. The first comprises a fundamental study of the physical and structural properties of Langmuir monolayers composed of sulfobetaine surfactants. Physiochemical properties of the films have been investigated through the use of Langmuir trough techniques. This has been used to support x-ray and neutron reflectometry data, from which structural parameters were derived. The second body of work involves attempts to find and/or characterize novel ways of aligning proteins at interfaces. Soluble proteins at lipid interfaces have been characterized in terms of their interactions with functionalized lipid monolayers. Specific interactions have been utilized to adsorb protein layers at the interface through interactions with His-tag chelating lipids within the monolayer. These have been characterized using neutron reflectometry and quartz crystal microbalance studies. Work has also been completed to design a suitable system for the adsorption of membrane proteins. This has involved aligning phospholipid bilayer nanodiscs at the lipid interface and subsequent characterization through neutron reflectometry.

Abstract:
In this study low temperature copper-gold bonding in ambient is demonstrated successfully with the help of organic monolayers. Further investigation is made to evaluate the influence of chain length of these monolayers to alleviate bonding temperature. We found that a single coat of organic monolayer on copper showed superior bond strength as compared to a double-coating on both copper and gold surfaces respectively. Despite effective surface passivation against oxide formation (Cu) and organic contaminant from ambient (Au) by long chain organic monolayers, when both surfaces are coated with the longest monolayer, weaker bond strength was observed. The results suggest that the ease of removal of organic monolayers from Cu and Au surface respectively prior to bonding plays a dominant role in enabling low temperature Cu-Au bonding.

Abstract:
The absorption of a monolayer of amphiphilic or surfactant molecules onto a surface can dramatically affect a number of the macroscopic properties of that surface. These properties, such as wetting by a fluid, lubrication of the solid, or chemical reactions of the surface, are of fundamental as well as technological importance. Our studies have focussed on the molecular scale structure of these monolayers and have attempted to probe how the structure depends on the deposition process used to absorb the monolayers. Further, by studying the molecular aspects of surfactant coated surfaces, we hope to gain insight into the nature of wetting and the other macroscopic phenomena which are profoundly affected by the presence of the surfactant monolayer.

Full text
Abstract:
Self-assembled monolayer coatings have shown great promise for dramatically reducing the tribological forces of adhesion and friction in microelectro-mechanical systems (MEMS). However, monolayer coatings often display significant degradation when exposed to extreme environments, dynamic sliding contact, and dynamic impact loading. This degradation is coupled with a corresponding increase in the tribological properties. In this study, the degradation of tridecafluorotri(dimethylamino)silane is examined under the typical operating conditions of MEMS technology using a specialized microdevice designed for characterizing the tribological behavior surface micromachines. Results of friction and adhesion degradation under normal loading and sliding contact are interpreted in relation to the primary degradation mechanisms of self-assembled monolayers.

Full text
Abstract:
SHG and THG signals were observed by reflection from the Langmuir-Blodgett monolayer of a Sec-butyl derivative of 4-methyl-6-nitro-2-quinolinamine. A floating monolayer was obtained by spreading chloroform solutions on ultrapure water and the subsequent evaporation of chloroform. The monolayer was deposited on a suitably treated glass slide at a compression rate of 100 cm2/min and a pressure of 12 mN/m. The 1064 nm fundamental wave emanating from a Nd:YAG laser was incident at a 45° angle on the monolayer surface, with the length of the substrate in a vertical plane. Signals were observed at 532 nm (SHG) and 355 nm (THG). When the sample was rotated by 90° in a vertical plane, the SHG signal vanished and the THG signal became much smaller. SHG and THG signals were also observed by reflection from a L-B film of 20 monolayers. When this sample was rotated by 90°, there was no significant difference in the intensity of the signals. The values of χ2 and χ3 were determined to be 10−6 and 5 × 10−4 esu, respectively, by using standard relations.

Full text
Abstract:
In this paper, we present a technique for freezing monolayers of micron and sub-micron sized particles onto the surface of a flexible thin film after the self-assembly of a particle monolayer on fluid-liquid interfaces has been improved by the process we have developed where an electric field is applied in the direction normal to the interface. Particles smaller than about 10 microns do not self-assemble under the action of lateral capillary forces alone since capillary forces amongst them are small compared to Brownian forces. We have overcome this problem by applying an electric field in the direction normal to the interface which gives rise to dipoledipole and capillary forces which cause the particles to arrange in a triangular pattern. The technique involves assembling the monolayer on the interface between a UV-curable resin and another liquid by applying an electric field, and then curing the resin by applying UV light. The monolayer becomes embedded on the surface of the solidified resin film.

Abstract:
Long chain alkylsilane monolayers used in the release process to protect MEMS devices from adhesion due to water adsorption also provide a very low coefficient of friction. One such monolayer, perfluorodecyltrichlorosilane (PFTS) has been shown to have very good thermal stability, keeping a water contact angle above 100° in air up to 400°C. [1] The monolayer will however wear under mechanical rubbing, causing the MEMS device to irreversibly adhere rendering it useless. Vapor phase lubricants (VPL) used in conjunction with self-assembled monolayers. may be the key to extending the life of rubbing contacts in MEMS. It is believed that the temperature characteristics of the VPL and its ability to replenish itself will provide a sufficient protective layer for the PFTS and extend the life of MEMS devices well into the range where their use in military and industrial applications can be fully realized. Here we have studied two vapor phase lubricants, tricresyl phosphate (TCP) and t-butyl phenyl phosphate (TBPP) on a PFTS monolayer. Previous work done with a quartz crystal microbalance has suggested that TBPP would be a better lubricant than TCP. [2] We have evaluated the effectiveness of these lubricant systems using a MEMS sidewall tribometer in a vacuum environment. Relationships between lubricant composition, behavior in an isolated asperity contact in the quartz crystal microbalance studies, and performance in a MEMS friction device will be discussed.

Abstract:
Lipid bilayers form nanopores on the application of an electric field. This process of electroporation can be utilized in different applications ranging from targeted drug delivery in cells to nano-gating membrane for engineering applications. However, the ease of electroporation is dependent on the surface energy of the lipid layers and thus directly related to the packing structure of the lipid molecules. 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) lipid monolayers were deposited on a mica substrate using the Langmuir-Blodgett (LB) technique at different packing densities and analyzed using atomic force microscopy (AFM). The wetting behavior of these monolayers was investigated by contact angle measurement and molecular dynamics simulations. It was found that an equilibrium packing density of liquid-condensed (LC) phase DPPC likely exists and that water molecules can penetrate the monolayer displacing the lipid molecules. The surface tension of the monolayer in air and water was obtained along with its breakthrough force.
