Advanced Science, EarlyView.A nano‐plasma device enables watt‐level on‐chip THz generation through picosecond switching triggered by secondary electron emission avalanche. An ultra‐dense electron sheet initiates nano‐plasma formation within a ∼100 nm gap, driving rapid energy release into an integrated resonator.

“Freedom” as a culture-bound concept in works by Friedrich Shiller
Studia Humanitatis, 2019 The article analyses the concept “freedom” in works by a great German poet Friedrich Schiller. The aim of the research is to distinguish characteristics of the concept. The continuous sampling method was used to collect the data for the study.

Direct-Splitting-Based CN-FDTD for Modeling 2D Material Nanostructure Problems
IEEE Open Journal of Antennas and Propagation, 2020 Incorporating a truncation of the complex-frequency-shifted perfectly matched layer (CFS-PML), the direct-splitting- based Crank-Nicolson finite-difference time-domain (CNDS-FDTD) is developed and applied to the infrared two-dimensional layered material (

CoRRIn this work we study arbitrary-order hybrid discretizations of Friedrichs systems. Friedrichs systems provide a framework that goes beyond the standard classification of partial differential equations into hyperbolic or elliptic, and are thus particularly suited for problems that include both diffusive and advective terms.

Electrochemical Modulation of Laser‐Induced Covalent Functionalization of Graphene
Advanced Science, EarlyView.Photoelectrochemical functionalization of graphene introduces the electrochemical potential as an additional parameter for the laser‐induced covalent modification of graphene. Tuning of the potential allows for amplification or suppression of the functionalization reaction with constant laser parameters, which enables in situ Raman analysis of ...

Predictive Registry Optimization of Molecular Adsorbates on Solid Surfaces
Angewandte Chemie, EarlyView.Local C–H “spikes” from a π‐conjugated backbone lock into graphene “pockets”. A geometric registry score turns images obtained by scanning tunneling microscopy at the solid/liquid interface into atomic‐scale adsorption models, enabling assignment of surface atropisomers in large π‐conjugated molecules.

Advanced Science, EarlyView.Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...
