An Enantioselective Alkene Aminoarylation to Form Chiral Indolines via Electrostatically‐Directed Palladium Catalysis

Angewandte Chemie, EarlyView.
Enantioselective aminoarylation of ortho‐allyl anilines is achieved under mild conditions. Key to success is the electrostatically‐directed nature of the key aminopalladation step, achieved by using the sulfonated chiral ligand sSPhos on palladium. A detailed study of electronic trends allows tuning of the sulfonamide protecting group to enable good ...

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales

Advanced Engineering Materials, EarlyView.
Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

The Bayesian Approach to Inverse Robin Problems

SIAM/ASA Journal on Uncertainty Quantification
In this paper we investigate the Bayesian approach to inverse Robin problems. These are problems for certain elliptic boundary value problems of determining a Robin coefficient on a hidden part of the boundary from Cauchy data on the observable part. Such a nonlinear inverse problem arises naturally in the initialisation of large-scale ice sheet models

Sustainable Poly(Lactic Acid)/Graphene Oxide Bioelectronic Platform for Neurotransmitters Sensing and Tunable Stimulation of Astrocytes

Advanced Materials, EarlyView.
This work introduces sustainable PLA/graphene oxide bioelectronic interfaces featuring electrodes with tunable conductivity and strong electrocatalytic performance. These platforms were used to implement a new method for tuning astrocyte Ca2+ signaling and for the efficient detection of key biomarkers.

Existence of bounded weak solutions of the Robin problem for a quasi-linear elliptic equation with p(x)-Laplacian

Electronic Journal of Qualitative Theory of Differential Equations, 2019
We prove the existence of bounded weak solutions to the Robin problem for an elliptic quasi-linear second-order equation with the variable $p(x)$-Laplacian.

Spectral homogenization for a Robin–Neumann problem [PDF]

Bollettino dell'Unione Matematica Italiana, 2016
We consider a Neumann-Robin spectral problem in a perforated domain $\Omeps$. By homogenization techniques we find the suitable homogenized problem and we discuss the asymptotics of eigenpairs, as the size of the perforation tends to zero. Our results involve an approach based on Višík lemma and the Mosco convergence of eigenspaces.

Grafted Low‐Leakage Si/AlN p‐n Diodes Enabled by Fluorinated AlN Interface

Advanced Materials Interfaces, EarlyView.
This work demonstrates a fluorination‐based interface engineering strategy that transforms oxygen‐terminated AlN surfaces into fluorine‐terminated interfaces for grafted p‐Si/n‐AlN diodes. By combining pseudo‐ALE oxide removal, XeF2 fluorination, and ultrathin SiNx stabilization, the engineered interface suppresses defect‐assisted reverse leakage by ...

On a Steklov-Robin eigenvalue problem

Journal of Mathematical Analysis and Applications, 2023
In this paper we study a Steklov-Robin eigenvalue problem for the Laplacian in annular domains. More precisely, we consider $Ω=Ω_0 \setminus \overline{B}_{r}$, where $B_{r}$ is the ball centered at the origin with radius $r>0$ and $Ω_0\subset\mathbb{R}^n$, $n\geq 2$, is an open, bounded set with Lipschitz boundary, such that $\overline{B}_{r}\subset

Scalable Task Planning via Large Language Models and Structured World Representations

Advanced Robotics Research, EarlyView.
This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...
