Colorimetry of Luminescent Lanthanide Complexes
Molecules, 2020 Europium, terbium, dysprosium, and samarium are the main trivalent lanthanide ions emitting in the visible spectrum. In this work, the potential of these ions for colorimetric applications and colour reproduction was studied.

f‐Block Element‐Based MOF Thin Films: A Platform for Luminescence, Sensing, and Energy Applications
Small, EarlyView.f‐Block element–based metal–organic framework (f‐MOF) thin films offer exceptional potential for luminescent, sensing, and energy‐related applications. This review surveys recent progress in their synthesis, characterization, and functional implementation, emphasizing the diversity of available thin‐film fabrication strategies. The convergence of these

Beads‐on‐a‐Tip testing for ultrasensitive antigen detection across a large dynamic range
Smart Molecules, EarlyView.Non‐specific adsorption on nitrocellulose membranes limits the sensitivity of conventional lateral flow immunoassays. Here, we present a Beads‐on‐a‐Tip immunoassay that replaces the membrane with magnetic beads for antigen capture and enrichment, while employing upconversion nanoparticles as background‐free luminescent reporters.

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.NaLa2F3(CN2)2 forms via solid‐state metathesis of LaF3 and Na2(CN2) at 550°C and remains stable under ambient air and humidity. The structure is based on [La(NCN)5F4] polyhedra with interstitial Na+; revealing an unconventional red emission when doped with Eu3+.

A Plant‐Based Platform for the Production of Bark Beetle Pheromones
Plant Biotechnology Journal, EarlyView.ABSTRACT Bark beetle species of the genera Ips and Dendroctonus represent a threat to forests in both North America and Europe. Under normal circumstances, these beetles recycle dying trees into nutrients, but under certain conditions, growing populations can overcome healthy tree defenses and cause severe economic loss in forestry.

Plant, Cell &Environment, EarlyView.ABSTRACT The multi‐elemental profile has repeatedly been proposed as a reliable indicator of the geographical origin of plant‐derived foods, as mineral composition accurately reflects the local soil geochemistry and environmental factors. However, this approach may fail in distinguishing specimens from nearby locations, which are expected to be exposed

Electronic properties of EuB6 in the ferromagnetic regime: Half-metal versus semiconductor
, 2005 To understand the halfmetallic ferromagnet EuB6 we use the Kondo lattice model for valence and conduction band. By means of a recently developed many-body theory we calculate the electronic properties in the ferromagnetic regime up to the Curie ...

Europium in the limelight [PDF]
Nature Chemistry, 2010 Jean-Claude Bunzli sheds light on why europium — an element that is neither abundant in the Earth's crust nor involved in biological processes — has nevertheless attracted a great deal of interest from chemists.

JCC Plus, Volume 1, Issue 2, March 2026.ABSTRACT Background and Aims Vedolizumab and ustekinumab are alternative therapies in patients with ulcerative colitis (UC) previously exposed to TNF inhibitors (TNFi). In Norway, treatment follows a national tender, and vedolizumab was first choice after TNFi discontinuation from 2016 to 2019 and ustekinumab from 2020 to 2022.
