Investigation of Halogen Substitution Effects in π‐Conjugated Organic Ligands of Chiral Hybrid Perovskites on Their Chiroptical Activity

open access: yesAdvanced Functional Materials, EarlyView.
The role of novel thiophene‐based ligands with halogen substitutions in enhancing the chiroptical and optoelectronic properties of 2D chiral HOIPs has been investigated. By tailoring ligand design, enhanced CD and CPL properties are achieved, with improved CPL discrimination in photodetectors.

MXene/PEDOT Functional Coatings on Flexible Microelectrode Arrays for Multianalyte In Vivo Neurochemical Sensing and Electrophysiology

open access: yesAdvanced Functional Materials, EarlyView.
A MXene/PEDOT coating enables multimodal functionality and dual‐analyte detection of dopamine and serotonin in flexible microelectrode arrays while enhancing electrophysiological recording quality. The anti‐fouling, low‐impedance interface overcomes key limitations of conventional coatings, providing a robust and versatile platform to investigate the ...

Cauchy non-integral formulas [PDF]

open access: yes, 2012
We study certain generalized Cauchy integral formulas for gradients of solutions to second order divergence form elliptic systems, which appeared in recent work by P. Auscher and A. Ros\'en.

Nonlinear boundary value problems for second order elliptic systems

open access: yesRocky Mountain Journal of Mathematics, 1984
The author treats boundary value problems for semilinear weakly coupled elliptic systems of second order \({\mathcal L}u_ r=f_ r(x,u,\partial u)\), \(x\in \Omega\), \(r=1,...,N\); \(B_ ru_ r=\Phi_ r\), \(x\in \partial \Omega\). Here \({\mathcal L}\) is a scalar, linear elliptic differential operator, the right hand sides \(f_ r\) are of weaker than ...

Chirality and Organization of Adsorbates Modify Surface Phonon Dynamics

open access: yesAdvanced Functional Materials, EarlyView.
Chirality and molecular organization are shown to influence surface phonon dynamics in gold films. Time‐resolved Joule heating measurements reveal that ordered homochiral monolayers increase the Debye temperature and disordered layers reduce it, while ordered racemic controls have no effect.

La gestion de l’eau à Bibracte (Saône-et-Loire), avant et après la Conquête romaine

open access: yesGallia, 2020
The hilltop of Bibracte, located on top of the Mount Beuvray hill, was one of the most important oppida of Gaul. The analysis of its hydraulic networks is a particularly rich field of study and is an original approach to understanding the types of water ...

Enhanced Endoscopic Internal Drainage of Gastric Abscess Through Additively Manufactured Stents

open access: yesAdvanced Healthcare Materials, EarlyView.
Postoperative gastric leaks are often treated with off‐label biliary double‐pigtail stents, yet conventional extruded designs are not optimized for leak anatomy, can migrate, and may limit abscess evacuation. PETALS is introduced to optimize transmural drainage geometry and enable patient‐specific 3D‐printable stents.
