Abstract:
The direct observation of atomic features in small crystalline particles supported by a thicker substrate is useful when characterizing materials such as electrocatalysts. However, particle definition becomes difficult to establish for catalyst crystallites less than 5nm in diameter on a support 5 to 10 times thicker, since the background contrast obscures the HREM image of the particle. Previous image calculations of 2.4nm sized particles on 10nm amorphous support have demonstrated further the problems associated with image interpretation of these small particles. The present method incorporates the matching of simulated images at varying thicknesses with computer enhanced images of small particles on amorphous supports in order to characterize atomic details at the surfaces of these particles.Catalyst material consisting of crystalline Ti02 particles on an amorphous Si02 support was developed so that the average particle size measured 7.0nm.

Abstract:
Silver particles of sizes ranging from about 2 to 100 nm embedded in a glass matrix were formed by silver-sodium ion exchange in sodium silicate glasses. By high-resolution electron microscopy examination, lattice contractions depending on the particle size were found that are comparable to or larger than those reported for nonembedded silver particles. From these lattice contractions values of the interface stress acting on the particles at room temperature as an effective compressive stress are determined. By deformation of the glasses at elevated temperatures, an elongation of spherical particles results that allows us to determine the interface stress at the deformation temperature. The large discrepancy of the resulting values points to an essential role of the cooling procedure taking place after the particle formation.

Full text
Abstract:
A new method, namely, force–distance curve mapping, was developed to directly measure the adhesion force of individual aerosol particles by atomic force microscopy. The proposed method collects adhesion force from multiple points on a single particle. It also takes into account the spatial distribution of the adhesion force affected by topography (e.g., the variation in the tip angle relative to the surface, as well as the force imposed upon contact), thereby enabling the direct and quantitative measurement of the adhesion force representing each particle. The topographic effect was first evaluated by measuring Polystyrene latex (PSL) standard particles, and the optimized method was then applied on atmospherically relevant model dust particles (quartz, ATD, and CJ-1) and inorganic particles (ammonium sulfate and artificial sea salt) to inter-compare the adhesion forces among different aerosol types. The method was further applied on the actual ambient aerosol particles collected on the western coast of Japan, when the region was under the influence of Asian dust plume. The ambient particles were classified into sea salt (SS), silicate dust, and Ca-rich dust particles based on individual particle analysis (micro-Raman or Scanning Electron Microscope/Energy Dispersive X-ray Spectroscopy (SEM-EDX)). Comparable adhesion forces were obtained from the model and ambient particles for both SS and silicate dust. Although dust particles tended to show smaller adhesion forces, the adhesion force of Ca-rich dust particles was larger than the majority of silicate dust particles and was comparable with the inorganic salt particles. These results highlight that the original chemical composition, as well as the aging process in the atmosphere, can create significant variation in the adhesion force among individual particles. This study demonstrates that force–distance curve mapping can be used as a new tool to quantitatively characterize the physical properties of aerosol particles on an individual basis.

Full text
Abstract:
This paper investigates the ultra-fast heating process of Cu-Pd bimetallic nanoparticles from an atomic-scale perspective, which is essential for laser manufacturing processes, such as laser cladding and selective laser melting. The behavior of high surface ratio nanoparticles during these processes is strongly influenced by their properties and the heating process, which is governed by atomic dynamics. Previous studies have mainly focused on the combination process in pure metallic nanoparticles under slow or isothermal heating, but this work demonstrates that the ultra-fast atomic dynamic process between bimetallic nanoparticles differs significantly. Specifically, in Cu-Pd nanoparticles, the combination process is primarily dependent on the surface atomic motion of the lower melting point particles rather than plastic deformation in the grain boundary between particles. Moreover, the ultra-fast heating process is size-dependent. For small nanoparticles, the atomic kinetics exhibit two different mechanisms depending on temperature: Low-temperature jointing is controlled by localized atomic rearrangement, while high-temperature coalition is governed by the atomic flow of surface atomic melting in the low-temperature melting particle. The combination mechanism is the same for large particles as it is for small particles at high temperatures. The findings of this study provide important insights into the behavior of bimetallic nanoparticles during ultra-fast heating and can inform the development of coat and lubricant.

Abstract:
In 1977, Z. Kam theorized that correlations of scattering patterns, measured by exposing a solution of randomly oriented identical particles to x-ray radiation, could yield detailed information on the internal structure of the individual particles [1]. During a single exposure (whose duration should be short compared to the particle rotational diffusion time), physical correlations arise whenever multiple photons scatter from the same particle into different directions. By averaging correlations from many exposures, we have demonstrated that one can extract this correlated signal from a background of uncorrelated single-direction scattering events from different particles [2]. This additional information can be used to place constraints on model structures of the particles under investigation, providing a method of structure refinement to atomic resolution. We recently observed correlated scattering from solutions of ~10^9 silver nanoparticles exposed to synchrotron radiation at a microfocus beamline at SSRL [2]. By auto- and cross- correlating the Bragg rings 111 and 200, five correlation peaks were resolved corresponding to the structure and symmetry of silver's reciprocal lattice. To transition from nanoparticles to biomolecule studies, we have performed several experiments at x-ray free electron laser centers (SLAC and SPring-8), and are working to refine analysis techniques.

Abstract:
It is shown that only stable particles can be elementary particles. The fundamental elementary particles are positive, negative and neutral particles of space. Photons and neutrinos are formed from them, which are elementary particles of electrons, positrons and protons. A neutral photon consists of a positive elementary particle of space, around which a negative elementary particle of space rotates. A neutrino consists of a negative elementary particle of space, around which a positive elementary particle of space rotates. An electron has a structure consisting of negative and neutral photons connected by negative elementary particles of space. The positron has a structure consisting of positive and neutral photons connected by negative elementary particles of space. A proton consists of a positively charged nucleus around which electrons rotate. The proton nucleus consists of positrons bound by neutrino particles. Atomic nuclei consist of positive and neutral protons connected by the exchange of electrons and neutrino particles. The carriers of electromagnetic interaction are positive and negative elementary particles of space. The carriers of the gravitational interaction are neutral elementary particles of space. Electromagnetic, gravitational and inertial forces are the forces of space. Space is an equilibrium system, just like the whole universe.

Abstract:
Abstract The properties of core-shell nanoparticles, which are used for many catalytic processes as an alternative to platinum, depend on the size of both the particle and the shell. It is thus necessary to develop a quantitative method to determine the shell thickness. Pd–Pt core-shell particles were analyzed using scanning transmission electron microscopy (STEM) and energy-dispersive X-ray spectroscopy (EDX). Quantitative EDX line profiles acquired from the core-shell particle were compared to four core-shell models. The results indicate that the thickness of the Pt shell corresponds to two atomic layers. Meanwhile, high-angle annular dark-field STEM images from the same particle were analyzed and compared to simulated images. Again, this experiment demonstrates that the shell thickness was of two atomic layers. Our results indicate that, in small particles, it is possible to use EDX for a precise atomic-scale quantitative analysis.

Abstract:
The problem of high-energy charged particle motion in the field of atomic strings and planes of oriented crystals, widely applied to control large accelerator beams and generate intense gamma radiation, is addressed. Following the previously developed theory of channeled particles incoherent scattering by crystal atom nuclei, we consider here the same by crystal atom electrons. The theory developed takes into consideration all the effects of momentum transfer between fast particles and electrons of atoms in a crystal in the range from the nuclear radius up to the many inter-atomic distances. The theory also includes the temperature-dependent Debye – Waller factor, as well as both the atomic form factors and scattering function, evaluated with the detail consideration of atomic structure. All the modifications of electron scattering in crystals are reduced to the value of the effective minimum momentum transfer, which by an order of value exceeds that one, related with the Bethe – Bloch mean atomic energy. Substituting this quantity to the expression for the mean square of the scattering angle of a classically moving particle makes it possible to compare the scattering by electrons and nuclei, while its joint use with the Rutherford cross section allows for the correct simulations of the planar channeling of positively charged particles in the thickest crystals, supposed to be used for the beam extraction from high energy accelerators, measurement of electromagnetic characteristics of short-living particles and development of intense narrow-band X-ray and gamma radiation sources based on crystal undulators.

Abstract:
In this thesis we used atomic force microscopy (AFM) to investigate systematically the behaviour of both electrostatically stabilised silica and sterically stabilised polystyrene (PS) colloidal systems on freshly cleaved mica substrates. For the silica colloidal nanoparticles we explored the effect of colloidal suspension concentration, particle size, and different application techniques on both the adsorption behaviour and subsequent structuring of the particles. For the PS colloidal nanoparticles we explored concentration effects and experimented with both dip-coating and droplet application techniques. We showed that silica nanoparticles adsorbed onto mica via irreversible adsorption that possessed lateral mobility due to the weak attraction between the nanoparticles and the substrate, facilitating subsequent capillary structuring of the nanoparticles during drying. We associated the effects of volume fraction with Debye screening, and kinetics effects with particle size and volume fraction. We also successfully imaged a partially dried film and showed the role of convective/capillary forces in the structuring of the nanoparticles. Studies with variations in particle size generated a number of different topography structures; with dewetting phenomena observed for 10 nm nanoparticles and the formation of crystalline structures for 100 nm nanoparticles. Spin coating techniques were used to produce even larger crystalline structures of nanoparticles. Size dependent ordering occurred for low concentration samples due to the polydispersity of the colloidal suspension. We showed that acceleration can affect interparticle spacing. We also studied the role of rotational speed on the crystallinity of the particle configurations and showed how fine tuning of rotational speed can generate large scale monolayer crystalline formations of nanoparticles.

Abstract:
The necessity to explore nanoscopic systems is ever increasing in the world of science and technology. This evolving need to study such physically small systems demands new experimental techniques and methodologies. Atomic force microscopy (AFM) is a versatile technique that can overcome many nanoscopic size limitations. AFM has been utilized in the world of nanotechnology to study physiochemical properties of particles, materials, and biomolecules through characterization of morphology, electrical and mechanical properties, binding interactions, and surface tension, among others. The work discussed herein is largely a report of several novel AFM methodologies that were developed to allow new characterization techniques of individual submicrometer particles and single biomolecular interactions. The effects of atmospheric aerosols on the radiative budget of the earth and climate are largely unknown. For this reason, characterizing the physiochemical properties of aerosols is vital. Since the particles that have relatively long lifetimes in the atmosphere are smaller than one micrometer in size, high resolution microscopy techniques are required to study them. AFM is a suitable technique for single particle studies because it has nanometer spatial resolution, can perform experiments under ambient pressure and variable relative humidity and temperature. These advantages were utilized here and AFM was used to study morphology, organic volume fraction, water uptake, and surface tension of nascent sea spray aerosol (SSA) particles as well as laboratory generated aerosols composed of relevant chemical model systems. The morphology of SSA was found, often times, to be composed of core-shell structure. With complementary microscopy techniques, the composition of the core and the shell was found to be inorganic and organic in nature, respectively. Novel methodology to measure water uptake and surface tension of single substrate deposited particles with AFM was established using chemical model systems. Furthermore, these methodologies were employed on nascent chemically complex SSA particles collected from a biologically active oceanic waveflume experiment. Finally, phase imaging was used to measure organic volume fraction on a single particle basis and was correlated with biological activity. Overall, this suite of single (submicrometer) particle AFM analysis techniques have been established, allowing future systematic studies of increasing complexity aimed at bridging the gap between the simplicity of laboratory generated particles and the complexity of nature. Another nanotechnology topic of interest is studying single biomolecular interactions. Virtually every biological process involves some amount of minute forces that are required for the biomolecular system to function properly. For example, there are picoNewton forces associated with enzymatic motions that are important for enzyme catalysis. The AFM studies reported here use a model enzyme/drug system to measure the forces associated with single molecule adhesion events. Escherichia Dihydrofolate Reductase (DHFR) is a target of cancer therapeutic studies because it can be inhibited by drugs like methotrexate (MTX) that are structurally similar to the natural folate binder but have much higher binding affinity. One of the obstacles of single molecular recognition force spectroscopy (MRFS) studies is the contribution of non-specific forces that create a source of uncertainty. In this study, DHFR and MTX are bound to the surface and the AFM tip, respectively, using several different linking molecules. These linking molecules included polyethylene glycol (PEG) and double stranded DNA (dsDNA) and the distribution of forces was compared to scenarios were a linker was not employed. We discovered that dsDNA and PEG both allow identification and removal of non-specific interaction forces from specific forces of interest, which increases the accuracy of the measurement compared to directly bound constructs. Traditionally, the linker of choice in the MRFS community is PEG. Here, we introduce dsDNA as a viable linker that offers more rigidity than PEG, which may be desirable in future molecular constructs. The majority of the work and data presented in this dissertation supports the establishment of new AFM methodologies that can be used to better explore single biomolecular interactions and individual submicrometer particles on the nanoscale.

Abstract:
<p> Atomic Layer Deposition (ALD) is a an excellent technique for depositing conformal thin films on complex geometries in layer by layer fashion. The mechanisms of depositing TiO<sub>2</sub>, platinum, and ethoxysilane molecules were probed with <i>in situ</i> Fourier transform infrared (FTIR) in order to better understand and improve the process. Each of these studies involves TiO<sub>2</sub>. </p><p> There are many uses for thin films of titanium dioxide, a semiconductor and high dielectric material. Current Atomic Layer Deposition (ALD) of TiO<sub> 2</sub> generally involves water or ozone, which can oxidize and corrode some substrates of interest. Ritala et al. successfully deposited an assortment of metal oxides using no water, but instead, metal alkoxides and metal halides as precursors. Presented is a study of ALD of titanium dioxide using titanium tetrachloride (TiCl<sub>4</sub>) and titanium tetraisopropoxide (TTIP). In situ Fourier transform infrared (FTIR) studies revealed that the mechanism for TiO<sub>2</sub> ALD using titanium tetrachloride and titanium tetraisopropoxide changed with temperature. At temperatures between 250 and 300&deg;, the isopropoxide species after TTIP exposures quickly underwent &beta;-hydride elimination to produce TiOH species on the surface. The observation of propene by quadrupole mass spectrometry supported the &beta;-hydride elimination reaction pathway. Deposition was investigated between 150 and 300&deg; on substrates including zirconia, alumina, and silica. Quartz crystal microbalance results and X-ray reflectivity showed that the system grew 0.5&ndash;0.6 &Aring;/cycle at 250&deg; X-Ray photoelectron studies also confirmed TiO<sub>2</sub> film growth. </p><p> In another aspect of ALD use, self-limiting chemistry assisted with terminating a surface with alkoxysilanes. Tire rubber contains additives such as carbon black or silica particles to provide strength. Although in theory Kevlar fibers would provide strength while lowering the density and increasing car fuel efficiency, in practice Kevlar fibers disperse only very poorly in the rubber, leading to inhomogeneity. In order the increase the mixing likelihood between rubber and Kevlar, the reactions of some sulfurous siloxanes were examined on both aluminum oxide and titanium oxide. The titanium oxide adhesion layer allowed the deposition of molecules on the surface that looked promising for improving mixing with rubber and decreasing the weight of tires. </p><p> Atomic layer deposition offers the possibility of more precision in platinum deposition. In a platinum deposition study, the nucleation and growth of non-conformal platinum on TiO<sub>2</sub> and WO<sub>x</sub> powder using Pt(hfac)<sub> 2</sub> and formalin was examined with in-situ FTIR and transmission electron microscopy (TEM). Interest in substitution of Pt/C as the oxidation reduction reaction catalyst in polymer electrolyte membrane fuel cells (PEMFCs) led to the ALD synthesis of Pt/WO<sub>x</sub> and Pt/TiO<sub>2</sub>. A nucleation period on the order of 100 cycles was observed, after which, platinum loading and particle size measurably increased with increasing cycle number. The adsorption of the hfac ligand on the metal oxide substrate effectively inhibits nanoparticle coalescence during the growth phase, which led to further investigation of its use as a site-blocking agent. The results showed that Pt particle distance could be increased with the use of hfacH.</p>

Abstract:
Abstract The polyamino acids, polyaspartate and its derivatives, are very effective inhibitors of crystallization. They also have utility as corrosion inhibitors. Particularly when they contain both polyanionic and hydrophobic domains, polyamino acids performed better in bench tests than polyacrylate-based materials as dispersants of mineral particles such as calcium carbonate, hydroxyapatite, kaolin, and iron oxide. The interactions of polyamino acids and crystal surfaces have been visualized at the atomic level by atomic force microscopy, lending insights into some mechanisms of action. Biodegradable and non-toxic polyamino acids can be produced in large quantity at low cost and may become useful in a variety of polymer technologies.

In 16th International Conference on Nuclear Engineering. ASMEDC, 2008. http://dx.doi.org/10.1115/icone16-48367.

Full text
Abstract:
Liquid sodium is used as the coolant of the fast breeder reactor (FBR). A weak point of sodium is a high chemical reactivity with water or oxygen. So an idea of chemical reactivity suppression of liquid sodium itself is proposed. The idea is that nano-meter size particles (hereafter called nano-particles) are dispersed in liquid sodium, and an atomic interaction which is generated between nano-particle and sodium atoms is applied to suppress the chemical reactivity. We call sodium that has dispersed the nano-particle a Nano-fluid. Three key technologies which are the trial manufacture of Nano-fluid, the reaction property of the Nano-fluid and applicability of Nano-fluid to FBR Plant have been carried out to develop the Nano-fluid.

Abstract:
Microelectronics is a complex field with ever-evolving technologies and business needs, fueled by decades of continued fundamental materials science and engineering advancement. Decades of dimensional scaling have led to the point where even the name microelectronics inadequately describes the field, as most modern devices operate on the nanometer scale. As we reach physical limits and seek more efficient ways for computing, research in new materials may offer alternative design approaches that involve much more than electron transport e.g. photonics, spintronics, topological materials, and a variety of exotic quasi-particles. New engineering processes and capabilities offer the means to take advantage of new materials designs e.g. 3D integration, atomic scale fabrication processes and metrologies, digital twins for semiconductor processes and microarchitectures. The wide range of potential technological approaches provides both opportunities and challenges. The Materials, Processes, and R and D Challenges in Microelectronics Future Directions workshop was held June 23-24, 2022, at the Basic Research Innovation Collaboration Center in Arlington, VA, to examine these opportunities and challenges. Sponsored by the Basic Research Directorate of the Office of the Under Secretary of Defense for Research and Engineering, it is intended as a resource for the S and T community including the broader federal funding community, federal laboratories, domestic industrial base, and academia.

Full text
Abstract:
Thin silica film formation from adsolubilization of inorganic silica precursors, letra-n-butoxysilane (TBOS) and tetraethyl orthosilicate (TBOS) in admicellar polymerization were studies. Cetyltrimethylammonium bromide (CTAB) at 700 uM and octyl phenol ethoxylate or Triton X-100 at 200 uM were used as surfactant templates for adsolubilizates TBOS and TBOS respectively. For the TBOS/CTAB system, the atomic force microscopy (AFM) topographic images showed fibers, hemispheres and flat layers existing along with increase of surface coverge on the mica surface as the TBOS feed concentration was increased. The results showed phase separation at low TBOS concentration, At high TBOS concentration, where there was no phase separation, the silica film was flat layer of multi-layer occurring from solublization of silicate anion of oligomers at the admicelle-aqueous solution interface. For the TBOS/ triton X-100 system, the surface morphology on the mica surfaceexhibited the thin homogeneous globular-shaped implying solubilization of TBOS at the admicelle-water interface. Addition of styrene monomer and 2.2-azobisosobutyronitrile (AIBN) initiator promoted adsolubilization of TEOS significantly in admicellar core of triton x-100. The surface morphology of the film depended on the amount of styrene and TEOS feed concentrations. As the styrene concentration increases, the periodic structures become more homogeneous. Higher concentration of styrene assisted the incorporation of TBOS in the polystyrene and inhibited the formation of silica particles on the surface, At 3 uM styrene and TEOS concentrations, styrene and TEOS synergistically fabricate the composite silica film with high coverage density.

Full text
Abstract:
The International Code Centres Network (CCN) is a group of experts developing codes and models for atomic, molecular and plasma-surface interaction data relevant to fusion applications. Variable subsets of the group are brought together by the IAEA Atomic and Molecular Data (AMD) Unit in order to discuss computational and scientific issues associated with code developments. At the 6th Technical Meeting described in this report, 11 experts in the field of Molecular Dynamics (MD) simulations of radiation damage reviewed CascadesDB, a database of atomic configurations generated by MD simulations of collision cascades. This database is developed and hosted by the AMD Unit and provides a central repository for the results of MD simulations of the evolution of a material’s structure following an impact by a high energy particle. Further plans to extend and enhance CascadesDB, and to establish a new database resource, DefectDB, containing density functional theory calculations of defect structures were also discussed.
