International Journal for Numerical Methods in Fluids, Volume 98, Issue 5, Page 557-577, May 2026.This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.

Геодинамика и тектонофизика, 2015 The paper presents the first tectonophysical reconstruction of initial divisibility of the protolithosphere as a result of convection in the cooling primitive mantle. Initial division of the protolithosphere into separate masses, i.e.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Drizzle initiation through the collision and coalescence of cloud droplets plays a crucial role in warm cloud precipitation. Recent theoretical studies suggest that the influence of collisional growth on the droplet size distribution can be quantified by a non‐dimensional drizzle number (Dz).

Scaling of Latitude‐Dependent Heat Transport in Geostrophic Convection
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Latitudinal variations in heat transport shape the thermal and magnetic evolution of rapidly rotating planets, stars, and icy moons. Although global simulations have revealed strong equatorial–polar contrasts, a predictive scaling theory has been lacking.

Fast and Slow Signal Propagation in Abiotic Polypeptide Assemblies
ChemBioChem, Volume 27, Issue 6, 27 March 2026.Proteinoid microspheres formed by thermal polymerization of amino acids exhibit spontaneous electrical potential fluctuations without genetic material, membranes, or ion channels. Multi‐electrode recordings and electron microscopy reveal composition‐dependent voltage oscillations, long‐term drifts, and correlated signals across electrodes.

The Barrel of Ilmenau: A large-scale convection experiment to study dust devil-like flow structures.
Meteorologische Zeitschrift, 2021 We present an experimental facility for the validation of numerical simulations on atmospheric dust devils in a controlled laboratory experiment. Dust devils are atmospheric air vortices with a vertical axis, and are formed by intense solar radiation and

Flow Compensation Recovers Sensitivity Lost to Convection in Gradient‐Enhanced TOCSY NMR Experiments
Chemistry–Methods, Volume 6, Issue 3, March 2026.Gradient‐enhanced TOCSY techniques are an essential tool in the NMR spectroscopist's toolkit. However, in the presence of convection, signal intensities can be severely diminished, an issue that is particularly common when using cryoprobes. Here, we present an easily implemented TOCSY experiment that reverses signal loss due to convection and ...

Controlling the Collective Transport of Large Passive Particles With Suspensions of Microorganisms
Small, Volume 22, Issue 18, 25 March 2026.Directional light stimuli induce the accumulation of microalgae in suspensions of Chlamydomonas reinhardtii. This accumulation triggers large scale bioconvection rolls capable of macroscale transport. Exploiting these bioconvective flows enables to collectively transport of hundreds of large passive particles, paving the way for future applications in ...
