Single-Particle Orbit Tracking - Setup, Characterisation and Application
… which records the 2-dimensional trajectories of single fluorescently labeled polystyrene beads, either 20nm or 50nm in diameter, with a high spatial and temporal resolution is introduced. Combining single molecule fluorescence techniques with a new method called single-particle orbit tracking the …

Single-particle instrument simulator: Bridging experiments and models
… of chemical species across individual aerosol particles, is crucial for quantifying aerosol optical, chemical, and micro-physical properties. For example, a particle’s absorptivity depends on whether light-absorbing components such as black carbon are externally or internally mixed. …

Signal variation in single particle aerosol mass spectrometry
Rapid and accurate detection of airborne micro-particles is currently an important problem in national security. One approach to such detection, bioaerosol mass spectrometry (BAMS), is currently under development at Lawrence Livermore National Laboratory. BAMS is a type of single particle aerosol …

Computational model of ductile erosion by single particle impact
Erosion by solid particle impact is a common problem in many industrial applications. It results due to mechanical contact between the particle and the metal surface, which in turn result in potential material losses. Erosion of machine parts by the small solid particle entrained in liquid or …

Single particle motion of polymeric, colloidal, and biological materials
Small particles and their dynamics are of widespread interest due both to their unique properties and their ubiquity. Here, we investigate several classes of small particles: colloids, polymers, and liposomes. All these particles, due to their size on the order of microns, exhibit significant …

Single particle spectrum of the two dimensional electron gas
… spectroscopy (TDCS), with which we measure the single particle density of states (DOS) of a 2DES with temperature-limited resolution. In TDCS, sharp voltage pulses disequilibrate a metallic contact from a nearby 2DES, inducing a tunnel current. We detect this current by monitoring the image …

2D image classification and alignment in single-particle Cryo-EM
Background and Objective: Single-particle Cryo-EM is a powerful tool for structural biologists to determine structures of macro-molecules at atomic resolution. In single-particle Cryo-EM, many individual biological molecular particles with identical structures are rapidly frozen at unknown, random …

Three-Dimensional Single Particle Tracking on the Two -Photon Microscope
We have developed a 3D single-particle-tracking (SPT) system based around the two-photon laser-scanning fluorescence microscope that can track particles in all three dimensions and at a high frequency response. We have implemented two different techniques to achieve this goal. Both techniques …

Advances in volumetric super-resolution microscopy and single-particle tracking
Single-molecule localisation microscopy (SMLM) has enabled optical microscopy to probe biological structures and processes at the nanometer scale. To accommodate the inherently 3D nature of biological structures, 3D-SMLM techniques---such as the astigmatic and double-helix point spread functions …
