Water Co‐Adsorption in Ultrathin Films of Ionic Liquids on Pt(111)

ChemistryOpen, EarlyView.
At 100 K, IL adsorption on D2O precovered Pt(111) partially displaces interfacial water resulting in a water‐IL co‐adsorbed layer. Upon heating to 130 K, IL ions migrate to the metal interface, thereby destabilizing adsorbed water as shown by the ≈10 K reduction in its desorption temperature.

Nondestructive Quantification of Water Ingress in PV Modules via Spectroscopic and Chemical Analysis for Enhanced Quality Assurance and On‐Site Inspection

Progress in Photovoltaics: Research and Applications, EarlyView.
This study presents a novel, nondestructive in situ method to quantify water ingress using near‐infrared absorption (NIRA) spectroscopy, calibrated with absolute water content via Karl–Fischer titration (KFT). The presented approach offers a powerful quality assurance and inspection tool for module manufacturers and solar developers, supporting ...

Universal discrete-time reservoir computers with stochastic inputs and linear readouts using non-homogeneous state-affine systems

, 2018
A new class of non-homogeneous state-affine systems is introduced for use in reservoir computing. Sufficient conditions are identified that guarantee first, that the associated reservoir computers with linear readouts are causal, time-invariant, and ...

Optimal Gain Selection for the Arbitrary‐Order Homogeneous Differentiator

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Differentiation of noisy signals is a relevant and challenging task. Widespread approaches are the linear high‐gain observer acting as a differentiator and Levant's robust exact differentiator with a discontinuous right‐hand side. We consider the family of arbitrary‐order homogeneous differentiators, which includes these special cases.

The topological classification of a family of quadratic differential systems in terms of affine invariant polynomials

, 2019
Summary: In this paper we provide affine invariant necessary and sufficient conditions for a non-degenerate quadratic differential system to have an invariant conic \(f(x,y) = 0\) and a Darboux invariant of the form \(f(x,y)^\lambda e^{st}\) with \(\lambda, s \in \mathbb R\) and \(s \neq 0\).

Recursive Feasibility of Nonlinear Stochastic Model Predictive Control With Gaussian Process Dynamics

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Data‐based learning of system dynamics allows model‐based control approaches to be applied to systems with partially unknown dynamics. Gaussian process regression is a preferred approach that outputs not only the learned system model but also the variance of the model, which can be seen as a measure of uncertainty.

The role of identification in data‐driven policy iteration: A system theoretic study

International Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Penetration enhancement effects of topically applied crosslinked hyaluronic acid

International Journal of Cosmetic Science, EarlyView.
Cross‐linked hyaluronic acid (HA) was demonstrated to enhance the topical delivery of a variety of hydrophilic actives into the skin. This phenomenon was observed for both small molecules and macromolecules, the latter of which was analysed with MALDI mass spectrometry imaging (MALDI‐MSI).
