Abstract:

Super-resolution microscopies, such as single molecule localization microscopy (SMLM), allow the visualization of biomolecules at the nanoscale. The requirement to observe molecules multiple times during an acquisition has pushed the field to explore methods that allow the binding of a fluorophore to a target. This binding is then used to build an image via points accumulation for imaging nanoscale topography (PAINT), which relies on the stochastic binding of a fluorescent ligand instead of the stochastic photo-activation of a permanently bound fluorophore. Recently, systems that use DNA to ac

Abstract:

AbstractSingle-molecule localization microscopy (SMLM) has allowed the observation of various molecular structures in cells beyond the diffraction limit using organic dyes. In principle, the SMLM resolution depends on the precision of photoswitching fluorophore localization, which is inversely correlated with the square root of the number of photons released from the individual fluorophores. Thus, increasing the photon number by using highly bright fluorophores, such as quantum dots (QDs), can theoretically fundamentally overcome the current resolution limit of SMLM. However, the use of QDs in

Abstract:

Di-octyl sebacic acid (DOS-A) is used as rust preventive oil on steel sheets. When applied below the maximum level of 75 mg/m2 per side, it is compatible with epoxy paint and does not require any pretreatment of the steel sheets. The incompatibility of DOS-A above this maximum could be caused by weak H-bonding between the acid and epoxy molecule, leading to blistering. The optimum oil level was determined through experimentation to avoid paint failure. It was also observed that a variance in the sheet surface roughness of ±0.4 μm did not appreciably affect paint failure.

Pressure sensitive paint (PSP) has become a useful tool to measure the surface pressure distribution of aerodynamic components replacing conventional pressure taps. For the PSP technique based on the luminescence quenching by oxygen, improvement of its sensitivity is important. In this study, we synthesized palladium octaethylporphyrin (PdOEP) as luminophor and embeded PdOEP in polydimethylsiloxane (PDMS) as polymeric binder to make up of pressure sensitive paints. We used UV/Vis spectrometer and spectrofluorimeter to study the absorption and phosphorescence spectra of PdOEP. In addition, by o

Abstract:

Paint durability is directly linked to the efficiency of the substrate pre-treatment system. The objective to treat the carbon steel surface prior to painting is to turn the unstable metal surface into a stable surface one, an inert base to receive the paint. This is the main function of the phosphatization processes, which enables good paint adherence and prevents the development of corrosion processes. The demand for cleaner technologies, with lower residue generation, makes the phosphatization an unappealing method, and in this context the use of nanoceramics is an alternative to phosphate

Abstract:

Abstract Single-stranded telomeric overhangs are ∼200 nucleotides long and can form tandem G-quadruplex (GQ) structures, which reduce their accessibility to nucleases and proteins that activate DNA damage response. Whether these tandem GQs further stack to form compact superstructures, which may provide better protection for longer telomeres, is not known. We report single-molecule measurements where the accessibility of 24–144 nucleotide long human telomeric DNA molecules is interrogated by a short PNA molecule that is complementary to a single GGGTTA repeat, as implemented in the FRET-PAINT

Recent advancements in single-molecule-based superresolution microscopy have made it possible to visualize biological structures with unprecedented spatial resolution. Determining the spatial coorganization of these structures within cells under physiological and pathological conditions is an important biological goal. This goal has been stymied by the current limitations of carrying out superresolution microscopy in multiple colors. Here, we develop an approach for simultaneous multicolor superresolution imaging which relies solely on fluorophore excitation, rather than fluorescence emission

Abstract:

In this study, quantitative gas chromatography–mass spectrometry (GC–MS) analysis was used to evaluate the influence of pigment concentration on the drying of oil paints. Seven sets of artificially aged self-made paints with different pigments (yellow ochre, red ochre, natural cinnabar, zinc white, Prussian blue, chrome oxide green, hematite + kaolinite) and linseed oil mixtures were analysed. In the pigment + linseed oil mixtures, linseed oil concentration varied in the range of 10 to 95 g/100 g. The results demonstrate that the commonly used palmitic acid to stearic acid ratio (P/S) to disti

Abstract:

The characteristics of commercially available refined and bodied linseed and tung oils, used as binders in the production of armour paints after historic recipes, are explored. Employed as anticorrosive paints mainly from the 1920s to 1960s, armour paints are greener alternatives that can be used for protection in industrial heritage conservation. Using a multi-analytical approach, chemical and physical properties of the fresh oils and solid films before and after accelerated ageing (ISO 16474-2:2013) were investigated to better understand which features are beneficial for the technical functi

Corrosion is one of the great problems that many industries face and that generates losses of millions of dollars worldwide. The aim of this work was to evaluate the capacity of polyaniline to increase the anticorrosive capacity of a commercial epoxy paint. Polyaniline was chemically synthesized by oxidation with ammonium persulfate and doped with oleic acid. Polyaniline was added to the paint in various concentrations to evaluate its behavior as an additive to improve the anticorrosion capacity on stainless steel samples.

Abstract:

In this work the mechanism of resonance is proposed as the way for determining of paint age, by application of this method. This method consists in accelerated paint ageing on the basis of resonance. Measuring is concerned with humidity of paint and it is a general method since water molecules are present in every material. The molecules of water have random distribution. They oscillate in shallow potential wells so that they can be ejected from paint with low energy quanta, thus decreasing the paint humidity by evaporation process. The high energy quanta accelerate this process of the paint a

Abstract:

DNA point accumulation in nanoscale topography (DNA-PAINT) is an easy-to-implement approach for localization-based super-resolution imaging. Conventional DNA-PAINT imaging typically requires tens of thousands of frames of raw data to reconstruct one super-resolution image, which prevents its potential application for live imaging. Here, we introduce a new DNA-PAINT labeling method that allows for imaging of microtubules with both DNA-PAINT and widefield illumination. We develop a U-Net-based neural network, namely, U-PAINT to accelerate DNA-PAINT imaging from a widefield fluorescent image and

AbstractDNA points accumulation for imaging in nanoscale topography (DNA-PAINT) is a super-resolution technique with relatively easy-to-implement multi-target imaging. However, image acquisition is slow as sufficient statistical data has to be generated from spatio-temporally isolated single emitters. Here, we train the neural network (NN) DeepSTORM to predict fluorophore positions from high emitter density DNA-PAINT data. This achieves image acquisition in one minute. We demonstrate multi-colour super-resolution imaging of structure-conserved semi-thin neuronal tissue and imaging of large sam

Abstract:

AbstractDNA points accumulation for imaging in nanoscale topography (DNA-PAINT) is a super-resolution fluorescence microscopy technique that achieves single-molecule ‘blinking’ by transient DNA hybridization. Despite blinking kinetics being largely independent of fluorescent dye choice, the dye employed substantially affects measurement quality. Thus far, there has been no systematic overview of dye performance for DNA-PAINT. Here we defined four key parameters characterizing performance: brightness, signal-to-background ratio, DNA-PAINT docking site damage and off-target signal. We then analy

AbstractThe DNA‐based single molecule super‐resolution imaging approach, DNA‐PAINT, can achieve nanometer resolution of single targets. However, the approach can suffer from significant non‐specific background signals originating from non‐specifically bound DNA‐conjugated DNA‐PAINT secondary antibodies as shown here. Using dye‐modified oligonucleotides the location of DNA‐PAINT secondary antibody probes can easily be observed with widefield imaging prior to beginning a super‐resolution measurement. This reveals that a substantial proportion of DNA probes can accumulate, non‐specifically, withi
