This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasmall nanoparticles have seen growing interest in several fields such as medicine, optics, and catalysis due to their unique size-dependent properties. Among these are fluorescent core-shell silica nanoparticles synthesized in water known as Cornell prime dots (C' dots), which are composed of a silica core and a poly(ethylene glycol) (PEG) shell. These C' dots are poised to become promising diagnostic and therapeutic tools in medicine, particularly for cancer applications. While spherical C' dots have already been in FDA-approved human clinical trials, exploration has expanded into different topologies of silica nanoparticles such as rings and cages, providing higher aspect ratios and higher surface area to volume ratios. For clinical translation of such nanostructures, quantitative assessments of their size and size dispersity remain parameters for further investigation and are critical to understanding and evaluating their effectiveness and safety in nanomedicine applications. Here, solution small-angle X-ray scattering was employed to characterize 3D structural details of ring-type silica nanostructures and their size and size dispersity. A hollow cylinder model provided consistent structural and dispersity parameters that were supported by transmission electron microscopy investigations.

Book Synopsis Suspensions of Colloidal Particles and Aggregates by : Frank Babick
Download or read book Suspensions of Colloidal Particles and Aggregates written by Frank Babick and published by Springer. This book was released on 2016-04-04 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the properties of particles in colloidal suspensions. It has a focus on particle aggregates and the dependency of their physical behaviour on morphological parameters. For this purpose, relevant theories and methodological tools are reviewed and applied to selected examples. The book is divided into four main chapters. The first of them introduces important measurement techniques for the determination of particle size and interfacial properties in colloidal suspensions. A further chapter is devoted to the physico-chemical properties of colloidal particles—highlighting the interfacial phenomena and the corresponding interactions between particles. The book’s central chapter examines the structure-property relations of colloidal aggregates. This comprises concepts to quantify size and structure of aggregates, models and numerical tools for calculating the (light) scattering and hydrodynamic properties of aggregates, and a discussion on van-der-Waals and double layer interactions between aggregates. It is illustrated how such knowledge may significantly enhance the characterisation of colloidal suspensions. The final part of the book refers to the information, ideas and concepts already presented in order to address technical aspects of the preparation of colloidal suspensions—in particular the performance of relevant dispersion techniques and the stability of colloidal suspensions.

Book Synopsis Smart Nanoparticles Technology by : Abbass A. Hashim
Download or read book Smart Nanoparticles Technology written by Abbass A. Hashim and published by BoD – Books on Demand. This book was released on 2012-04-18 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few years, Nanoparticles and their applications dramatically diverted science in the direction of brand new philosophy. The properties of many conventional materials changed when formed from nanoparticles. Nanoparticles have a greater surface area per weight than larger particles which causes them to be more reactive and effective than other molecules. In this book, we (InTech publisher, editor and authors) have invested a lot of effort to include 25 most advanced technology chapters. The book is organised into three well-heeled parts. We would like to invite all Nanotechnology scientists to read and share the knowledge and contents of this book.

Book Synopsis Synthesis, Characterization and Structure Control of Ordered Mesoporous Silica Nanoparticles by : Teeraporn Suteewong
Download or read book Synthesis, Characterization and Structure Control of Ordered Mesoporous Silica Nanoparticles written by Teeraporn Suteewong and published by . This book was released on 2011 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ordered mesoporous silica materials are characterized by uniform and tunable pore size, high surface area and large pore volume. In particular, nano-sized ordered mesoporous silica particles have drawn interest from several fields, including biorelated areas, because silica is benign, possesses chemical stability and can be integrated with other materials. Structural aspects, such as pore connectivity, geometry and pore size are known to govern materials performance. Extensive efforts have been devoted to synthesize mesoporous silica particles with different structures, functionalities and sizes. In contrast, only a small number of studies so far have concentrated on the formation mechanism of these particles. This is hence the focus of the present dissertation. The first part reports on the synthesis and characterization of ordered mesoporous silica nanoparticles with and without embedded magnetic nanoparticles. The formation mechanism of silica nanocomposites is investigated by capturing particle formation at different time points during the synthesis. A combination of transmission electron microscopy (TEM) and small angle x-ray scattering (SAXS) is used to characterize the structure evolution of resulting materials. Incorporating organic moieties into the silica matrix provides additional functionalities to ordered mesoporous silica nanoparticles. However, it often leads to disordered pore structure or pore blockage. The second part demonstrates the preparation of aminated and ordered mesoporous silica nanoparticles using a cocondensation method. Increasing the amount of aminosilane in the synthesis feed causes a structural transition of organically modified particles from hexagonal to cubic. Pore size of ordered mesoporous silica and aminated ordered mesoporous silica nanoparticles can be tailored by the addition of a swelling agent during the synthesis. The structural transformation from hexagonal to cubic is also observed in the latter case, albeit at different amino silane concentrations. The final part reports on the internalization of nanoparticles into cells. Fluorescent aminated mesoporous silica nanoparticles are first prepared and then coated with poly(ethylene glycol) to improve particle stability and lower protein adsorption. Dye-labeled aminated mesoporous silica nanoparticles are spontaneously internalized by cells.

Book Synopsis Gas‐phase Synthesis of Silica Nanoparticles: Reaction Kinetics, Synthesis and Characterization by : Ali Abdali
Download or read book Gas‐phase Synthesis of Silica Nanoparticles: Reaction Kinetics, Synthesis and Characterization written by Ali Abdali and published by Cuvillier Verlag. This book was released on 2014-04-25 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gas-phase kinetics of the decomposition of tetraethoxysilane (TEOS) and hexamethyldisiloxane (HMDSO) and the formation and growth of silica nanoparticles were studied. The kinetics study was carried out in shock-heated gases with species measurements by high-repetition-rate time-of-flight mass spectrometry. The mass spectra indicate the formation of Si(OH)4 from the decomposition of TEOS while during HMDSO decomposition several Silicon-containing species were found, such as Si atoms, SiO and SiCH3. The ignition-delay time of the precursors in oxygen-containing bath gases was studied by observing the OH* emission signal behind the reflected shock wave. The ignition delay times of TEOS and HMDSO are strongly temperature dependent and the Arrhenius parameters were determined. Silica-particle formation and growth from TEOS and HMDSO were investigated in a hybrid microwave-plasma hot-wall reactor and a low-pressure premixed H2/O2/Ar flame reactor by in-situ and ex-situ measurements. Particle sizes distributions were determined by particle mass spectrometry and the spatial gas-phase temperature distribution was measured with multi-line NO-LIF thermometry. The present research work provides data and new understanding of TEOS and HMDSO decomposition kinetics and particle formation and growth of silica nanoparticles in the gas-phase. These data can be used as input for computational fluid dynamics simulations and hence for the design of reactors for the gas-phase synthesis of highly specific nanoparticles.

Book Synopsis Challenges in Characterizing Small Particles by : National Research Council
Download or read book Challenges in Characterizing Small Particles written by National Research Council and published by National Academies Press. This book was released on 2012-05-02 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small particles are ubiquitous in the natural and built worlds and have tremendous impact throughout. However, a lack of understanding about the properties and chemical composition of small particles limits our ability to predict, and control their applications and impacts. Challenges in Characterizing Small Particles: Exploring Particles from the Nano- to Microscales summarizes presentations and discussions at a 2010 National Academies roundtable. Speakers at this roundtable discussed the crucial types of information that need to be determined about small particles in different media. They also explored the critical importance of small particles in environmental science, materials and chemical sciences, biological science, and engineering, and the many challenges involved in characterizing materials at the nano- and microscales. The discussions on characterization included static, dynamic, experimental, computational, and theoretical characterization. The workshop also included several "research tool" presentations that highlighted new advances in characterizing small particles.
