Single particles as resonators for thermomechanical analysis [PDF]

Nature Communications, 2020
Eliminating the need for cleanroom fabrication for thermomechanical characterization of organic samples in a biomedical setting remains a challenge. Here, the authors propose the use of a single drug and collagen particles as resonators, enabling direct ...

Tracking single particles for hours via continuous DNA-mediated fluorophore exchange [PDF]

Nature Communications, 2021
The length of single-particle tracking experiments are limited due to photobleaching. Here the authors achieve long-term single-particle tracking with continuous fluorophore exchange in DNA-PAINT and use this to observe DNA origami on lipid bilayers for ...

Volume reflection of ultrarelativistic particles in single crystals [PDF]

Physical Review Special Topics. Accelerators and Beams, 2007
An analytical description of volume reflection of charged ultrarelativistic particles in bent single crystals is considered. The relation describing the angle of volume reflection as a function of the transversal energy is obtained.

Single-particle virology [PDF]

Biophysical Reviews, 2020
AbstractThe development of advanced experimental methodologies, such as optical tweezers, scanning-probe and super-resolved optical microscopies, has led to the evolution of single-molecule biophysics, a field of science that allows direct access to the mechanistic detail of biomolecular structure and function.

Vibration induced segregation of single large particles [PDF]

EPJ Web of Conferences, 2021
The vibration-induced segregation (e.g., rising of one large intruder - so called Brazil Nut Effect (BNE)) is studied by discrete element method. Vibration frequency and amplitude are two dominating factors in the occurrence of BNE and a phase diagram is

3D-printed sheet jet for stable megahertz liquid sample delivery at X-ray free-electron lasers

IUCrJ, 2023
X-ray free-electron lasers (XFELs) can probe chemical and biological reactions as they unfold with unprecedented spatial and temporal resolution. A principal challenge in this pursuit involves the delivery of samples to the X-ray interaction point in ...

Nonlocal single particle steering generated through single particle entanglement [PDF]

Scientific Reports, 2021
AbstractIn 1927, at the Solvay conference, Einstein posed a thought experiment with the primary intention of showing the incompleteness of quantum mechanics; to prove it, he employed the instantaneous nonlocal effects caused by the collapse of the wavefunction of a single particle—the spooky action at a distance–, when a measurement is done.

Unsupervised learning approaches to characterizing heterogeneous samples using X-ray single-particle imaging

IUCrJ, 2022
One of the outstanding analytical problems in X-ray single-particle imaging (SPI) is the classification of structural heterogeneity, which is especially difficult given the low signal-to-noise ratios of individual patterns and the fact that even ...
