Consentful Contention in Revolutionary Times: Debating Elite Corruption at Communist Party Congresses in Poland and East Germany

open access: yesZeitschrift für Ostmitteleuropa-Forschung, 2023
Existing scholarship treats congresses of the ruling communist parties in the Eastern Bloc as staged performances intended to manufacture support and signal new policy trends. This article, using the examples of extraordinary party congresses held during

Shape of Dynamical Heterogeneities and the Stokes-Einstein and Stokes-Einstein-Debye Relations in Suspensions of Colloidal Ellipsoids

open access: yes, 2014
We examine the role of shape of dynamical heterogeneities on the validity of the Stokes-Einstein (SE) and Stokes-Einstein-Debye (SED) relations in quasi-two-dimensional suspensions of colloidal ellipsoids.

Self-consistent two-phase AGN torus models - SED library for observers [PDF]

open access: yes, 2015
We assume that dust near active galactic nuclei (AGNs) is distributed in a torus-like geometry, which can be described as a clumpy medium or a homogeneous disk, or as a combination of the two (i.e. a two-phase medium).

Cathode Upcycling for Direct Recycling of Lithium‐Ion Batteries Using a Precipitation Approach

open access: yesAdvanced Energy Materials, EarlyView.
To improve the circularity of lithium‐ion batteries, researchers develop a low‐cost method to increase the energy density of directly recycled cathodes. Through a precipitation process, low‐nickel materials are converted to high‐nickel compositions. Using synchrotron 3D X‐ray imaging and diffraction, they track nickel diffusion during high‐temperature ...

Steam caps in geothermal reservoirs can be monitored using seismic noise interferometry

open access: yesCommunications Earth & Environment, 2023
Harvesting geothermal energy often leads to a pressure drop in reservoirs, decreasing their profitability and promoting the formation of steam caps. While steam caps are valuable energy resources, they also alter the reservoir thermodynamics.

The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

open access: yesAdvanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...
