Combination of a UPO‐Based Epoxidation With a Subsequent Ring‐Opening Reaction for the Synthesis of Amino Alcohols

open access: yesChemBioChem, Volume 27, Issue 5, 13 March 2026.
The synthesis of aromatic amino alcohols via a combination of an unspecific peroxygenase‐catalysed reaction, oxyfunctionalization, and addition of selected nucleophiles and electrophiles in a highly atom‐efficient manner was investigated. This study presents the design to aim for an atom‐efficient chemo‐enzymatic synthesis route towards aromatic amino ...

DIGITAL INFORMATION PROCESSING: THE LIE GROUPS DEFINING THE FILTER BANKS OF THE COMPACT DISC

open access: yesTASK Quarterly, 2002
The versality of the compact disc (CD) has quickly become apparent to manufacturers and users alike. Exceeding the expectations of even its most ardent supporters, the CD holographic disc storage system has become one of the most successful consumer ...

Comparing three possible hypoelliptic Laplacians on the 5-dimensional Cartan group via div-curl type estimates

open access: yesAdvanced Nonlinear Studies
On general Carnot groups, the definition of a possible hypoelliptic Hodge-Laplacian on forms using the Rumin complex has been considered in (M. Rumin, “Differential geometry on C-C spaces and application to the Novikov-Shubin numbers of nilpotent Lie ...

Observability of linear systems on the Heisenberg Lie group

open access: yes
In control theory, understanding the observability property of a system is crucial for effectively managing and controlling dynamical systems. This property empowers us to deduce the internal state of a system from its outputs over time, even when direct measurements are impossible.

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

open access: yesAdvanced Functional Materials, Volume 36, Issue 18, 2 March 2026.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Interplay of Backbone Conformation, Morphology and Thermoelectric Properties of Benzodifuranone‐Isatin Acceptor Polymers

open access: yesAdvanced Electronic Materials, Volume 12, Issue 6, 23 March 2026.
Modification of polymer backbone via halogenation and comonomer selection leads to conjugated backbones of different stereoelectronic properties, thin film morphologies, and electrical characteristics. The interplay of conformational isomerism, coplanarity, backbone curvature, backbone orientation, and ordering in thin films, electrical conductivity ...

Vacancy‐Controlled Lattice Dynamics and Magnetism in Mn‐Doped CeO2−δ Nanocrystals

open access: yesAnnalen der Physik, Volume 538, Issue 3, March 2026.
ABSTRACT Mn‐doped CeO2−δ${\rm CeO}_{2-\delta }$ nanocrystals provide a model system to quantify how defect chemistry controls emergent magnetism in a wide‐gap oxide. Single‐phase fluorite Ce1−xMnxO2−δ${\rm Ce}_{1-x}{\rm Mn}_x{\rm O}_{2-\delta }$ (0≤x≤0.09$0 \le x \le 0.09$) nanocrystals exhibit nonmonotonic changes in lattice parameter, microstrain ...

Photo‐Excitations in Halide Perovskites: Where Do Simulations and Experiments Meet?

open access: yesLaser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
Aiming to bridge the gap between simulations and measurements of light–matter couplings and photo‐excitations in new functional materials, this perspective highlights insights and bottlenecks of state‐of‐the‐art experimental and theoretical methods (2D electronic spectroscopy vs.
