“…That means that there were few HGM breakages in the preparation process. HGM added in the uncured AG-80/m-XDA system increased the contact area of raw materials [ 43 , 44 ]. For higher curing reaction rates of AG-80 epoxy resin and m-XDA curing agent, the cross-linked network structure was more easily formed, so the viscosity of the mixture became higher.…”

In order to synthesize a new kind of buoyancy material with high-strength, low-density and low-water-absorption and to study the curing reaction of tetraglycidylamine epoxy resin with an aromatic amine curing agent, the non-isothermal differential scanning calorimeter (DSC) method is used to calculate the curing kinetics parameters of N,N,N′,N′-tetraepoxypropyl-4,4′-diaminodiphenylmethane epoxy resin (AG-80) and the m-xylylenediamine (m-XDA) curing process. Further, buoyancy materials with different volume fractions of hollow glass microsphere (HGM) compounded with a AG-80 epoxy resin matrix were prepared and characterized. The curing kinetics calculation results show that, for the curing reaction of the AG-80/m-XDA system, the apparent activation energy increases with the conversion rates increasing and the reaction model is the Jander equation (three-dimensional diffusion, 3D, n = 1/2). The experimental results show that the density, compressive strength, saturated water absorption and water absorption rate of the composite with 55 v % HGM are 0.668 g·cm−3, 107.07 MPa, 0.17% and 0.025 h−1/2, respectively. This kind of composite can probably be used as a deep-sea buoyancy material.

Imaging and visualization of cells and tissues are important when studying various biological phenomena. The ability to provide spatial information with molecular and chemical specificity may increase our insight and understanding of biological problems within life sciences. There is a need for well suited analytical imaging tools for addressing challenges that can increase our knowledge from the visualization on the cellular and subcellular level. In this thesis, we have focused on the use of surface analytical techniques based on the photoemission process. Synchrotron based surface analytical tools such as mirror electron microscopy, low energy electron microscopy, X-ray photoelectron spectroscopy, X-ray photoemission electron microscopy and near edge X-ray absorption fine structure spectroscopy were used to obtain highly resolved chemical information for both fundamental biological systems and technical innovations.

“…[ 16 ] Commonly used technologies use either interferometric approaches as X‐Ray reflectometry (XRR) and ellipsometry or the atomic level detection methods such as X‐Ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). [ 1 ] However, various inherent limitations can be identified, such as contrast requirements, lack of lateral resolution, refractive index knowledge and requiring high vacuum conditions. [ 17,18 ] SPM and AFM allow contact or dynamic mode probing immersed in solution but fail to detect floating samples, and thus, biological samples should be attached to the surface.…”

Surface nanostructures include thin/ ultrathin films, whose precise characterization is important in semiconductors, optical components, and wear-resistance coatings. Also, surface-assembled and densely packed nanoparticle clusters such as viruses, [4,5] colloidal molecules, [6] DNA, [7] and supramolecules [8] form extended complex surface nanostructures which could be used to explore new paradigms in nanobiotechnology. Analyzing the surface bio-nanotopography could open new possibilities of bio-inspired system engineering. [9] In biology, the nanotopographical measurement scaled down to a single-molecule level eventually leads to the nanodisplaying of compartments in densely packed biological environments. Thus, depicting the morphology of macromolecular structures with high spatial and genomic resolution is expected to reveal the complex biological structures and underlying molecular mechanisms. [10] Various microscale characterization techniques enable the study of physicochemical properties of microstructures, such as scanning electron microscopy (SEM), energy dispersive X-Ray analysis (EDAX), and Raman spectroscopy. Surface micro-and submicro topographies can be measured by a wide range of optical instruments such as phase shifting interferometry and coherence scanning interferometry (CSI), point autofocus instrument (PAI), focus variation microscopy (FVM), and imaging confocal microscopy (ICM). [11,12] However, such techniques and particularly the commercial interferometric ones are incapable of precise measurement when it comes to irregular topographies of materials with complex optical properties and nanometer resolution. [13] The advent of nanoscopic scale techniques such as scanning tunneling microscopy (STM), atomic force microscopy (AFM), and scanning probe microscopies (SPM) initiates an important step to surface micro-/nanomorphological characterization. [14,15] Nonetheless, AFM and the contact profilometer are the only promising techniques for exact surface topography quantification. These are inclusively used to assess the behavior of optical measurement techniques, but they are very time-consuming and surface-intrusive. [11] Quantifying the micro-/nanotopography of thin films, surface nanostructures and nano-bio behavior at liquid/solid interfaces A nearfield-based topographic imaging method is presented to obtain 3D micro-/nanotopography in labelled structures over lateral ranges of hundreds of micrometers with an axial thickness from 1000 nm to thin layers of below 100 nm. The contactless axial nearfield-based fluorescence imaging topography (CLeANFIT) nanometrology technique is based on a modified model used in nearfield-based super-resolution imaging and sensing. The modified approach allows converting fluorescence lifetimes into nanoscale thicknesses of a fluorescent material in the nearfield of a metal surface. CLeANFIT is used to characterize the drying process of a fluorophore-doped poly(vinyl alcohol)/water droplet and it allows to quantify the nanomorphological patterns formed during an...
