Uniform confidence bands for functions estimated nonparametrically with instrumental variables [PDF]
, 2009 This paper is concerned with developing uniform confidence bands for functions estimated nonparametrically with instrumental variables. We show that a sieve nonparametric instrumental variables estimator is pointwise asymptotically normally distributed ...

A Borane Sandwich Analogue of Ferrocene
Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.The first ferrocene analogue with two boron‐based ligands is identified through a global exploration of the FeB10H20 potential energy surface. The η5,η5‐Fe(B5H10)2 complex emerges as the global minimum, showing that metal coordination inverts borane stability and enables aromatic boron rings inaccessible in isolation.

The star function for meromorphic functions of several complex variables [PDF]
, 2019 We define an analogue of the Baernstein star function for a meromorphic function f in several complex variables. This function is subharmonic on the upper half-plane and encodes some of the main functionals attached to f. We then characterize meromorphic

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.

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane
Small, EarlyView.Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Small, EarlyView.This research demonstrates real‐time visualization of supramolecular sol‐gel transitions using Fluorescence Lifetime Imaging Microscopy (FLIM). By leveraging 5D visualization, integrating 3D space, time, and polarity resolution, we achieved maskless sub‐micrometric photopatterning within the gel matrix.
