Impedance Spectroscopy of Bifurcation Oscillations in S‐Type Self‐Oscillatory Devices
Advanced Physics Research, EarlyView.Impedance spectroscopy (IS) reveals stability regimes and bifurcation dynamics in S‐type self‐oscillatory devices. By linking nonlinear control theory with frequency‐domain measurements, experimental signatures of oscillations, entrainment, and phase locking are directly identified.

Batteries &Supercaps, Volume 8, Issue 3, March 2025.This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

ChemFoodChem, EarlyView.Dehulling combined with twin‐screw extrusion improves the nutritional and functional properties of steam treated navy beans. Protein digestibility increases while phytic acid is reduced by 43% and trypsin inhibitors are inactivated. Enhanced expansion, solubility, and sensory quality highlight the potential of dehulled bean flours for developing ...

Supramolecular Host‐Guest Complexation Dynamics by Cost‐Efficient Electronic Structure Methods
Chemistry – A European Journal, EarlyView.We present a cost‐effective multilevel workflow for the kinetic profiling of host–guest systems, illustrated with cucurbit[6]uril and alkylammonium cations. The method combines rapid docking and reaction path searches at the semi‐empirical level, with refinement of the results using modern density functional theory, accurately reproducing experiment ...

Helium atom iso-electronic series study by hyperspherical method
, 2002 In this work we analyze the spectrum of the iso-electronic series of the helium atom by using the hypespherical adiabatic method. This method allows the study of the energy levels of atomic systems by means of a set of potential curves, similarly to the ...

Chemistry – A European Journal, EarlyView.ABSTRACT The rational design of hybrid nanomaterials with precisely controlled properties remains a central challenge in materials science. While atomically precise gold nanoclusters (Au‐NCs) offer molecule‐like control over a metallic core, tuning their optoelectronic behavior via surface engineering is often empirically driven.
