Irreversibble Bimolecular Reactions of Langevin Particles
, 2000 The reaction A+B --> B is studied when the reactants diffuse in phase space, i.e. their dynamics is described by the Langevin equation. The steady-state rate constants are calculated for both the target (static A and mobile B's) and trapping (mobile A ...

Skewed superstatistical distributions from a Langevin and Fokker-Planck approach [PDF]
, 2010 The superstatistics concept is a useful statistical method to describe inhomogeneous complex systems for which a system parameter $\beta$ fluctuates on a large spatio-temporal scale.

Advanced Functional Materials, EarlyView.A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Regularly varying correlation functions and KMO-Langevin equations
Hokkaido Mathematical Journal, 1997 The author considers the linear stochastic delay equation \[ \dot X=-\int_{-\infty}^t \gamma(t-s)\dot X(s) ds+\alpha\dot B(t), \] where \(\alpha>0\), \(\dot B\) is a Gaussian white noise, and \(\gamma\colon(0,\infty)\to(0,\infty)\) is a function of the form \(\gamma(t)=\int_0^\infty \exp\{-t\lambda\} d\rho(\lambda)\), \(t>0\), where \(\rho\) is a Borel

Green function, quasi-classical Langevin and Kubo–Greenwood methods in quantum thermal transport [PDF]
Journal of Physics: Condensed Matter, 2019 With the advances in fabrication of materials with feature sizes at the order of nanometers, it has been possible to alter their thermal transport properties dramatically. Miniaturization of device size increases the power density in general, hence faster electronics require better thermal transport, whereas better thermoelectric applications require ...

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles
Advanced Functional Materials, EarlyView.Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

Backstreaming effects on probing postsaddle dissipation with light particle multiplicity
Physics Letters B, 2020 Nuclear dissipation retards fission. Using the stochastic Langevin model, we study pre- and post-saddle emitted neutrons, protons and α particles of heavy 245Cf nuclei as a function of the postsaddle dissipation strength (β) in the absence and presence ...

Advanced Functional Materials, EarlyView.MagPiezo enables wireless activation of endogenous Piezo1 channels without genetic modification using 19 nm magnetic nanoparticles and low‐intensity magnetic fields. It generates torque forces at the piconewton scale to trigger mechanotransduction in endothelial cells, standing as a novel platform to interrogate and manipulate Piezo1 activity in vitro.
