XRF and XRPD data sets in ternary mixtures with high level micro-absorption and/or preferred orientations problems for phase quantification analysis

Data in Brief, 2021
Micro-absorption (MA) and/or preferred orientations (PO) are two among the major problems affecting quantitative phase analysis (QPA) by X-ray Powder Diffraction Data (XRPD) in industrial samples such as minerals and ores, additives, cements, friction ...

Intramolecular N···F Pnictogen Bond Mitigates the Explosive Behavior of Azido‐L‐Phenylalanines

ChemistryEurope, Volume 4, Issue 4, April 2026.
An intramolecular N···F pnictogen bond is the key for the chemical stabilization of the fluorinated azido‐L‐phenylalanines, mitigating the risk of explosion and thus facilitating the handling and storage of these materials. Organic azides are versatile intermediates but are plagued by intrinsic instability and potential explosiveness. Here, it is shown

An atomistic model of a disordered nanoporous solid: Interplay between Monte Carlo simulations and gas adsorption experiments

AIP Advances, 2017
A combination of physisorption measurements and theoretical simulations was used to derive a plausible model for an amorphous nanoporous material, prepared by Friedel-Crafts alkylation of tetraphenylethene (TPM), leading to a crosslinked polymer of TPM ...

Design of Molecular Lanthanide‐Based Quantum Light Sources for On‐Chip Integration

Advanced Optical Materials, Volume 14, Issue 11, 20 March 2026.
Rigid lanthanide complexes with a tetrapodal tris‐benzimidazolic ligand exhibit narrow, well‐resolved visible/NIR emission profiles suitable for quantum photonics. The EuL complex features an exceptionally sharp 5D₀→7F₀ transition enabled by an LMCT mechanism that suppresses inhomogeneous broadening.

Biodiversity and its restoration in limestone quarries: a review

Restoration Ecology, Volume 34, Issue 3, March 2026.
Abstract Introduction Limestone quarries impact natural areas, and they are spreading in relation to human population growth. Little is known about the impact of limestone quarries and their restoration on biodiversity. Objectives This review aims to provide an overview of how biodiversity is assessed in limestone quarries, how it impacts biodiversity,

The geometry of supermanifolds and new supersymmetric actions

Nuclear Physics B, 2015
This is the first of two papers in which we construct the Hodge dual for supermanifolds by means of the Grassmannian Fourier transform of superforms. In this paper we introduce the fundamental concepts and a method for computing Hodge duals in simple ...

Supergravity actions with integral forms

Nuclear Physics B, 2014
Integral forms provide a natural and powerful tool for the construction of supergravity actions. They are generalizations of usual differential forms and are needed for a consistent theory of integration on supermanifolds.

Local Habitat Features, but Not Isolation, Shape Alpine Odonate Assemblages: Implications for Modelling and Conservation

Diversity and Distributions, Volume 31, Issue 10, October 2025.
ABSTRACT Aim Human impacts and climate change are intensifying the fragmentation of freshwater habitats, raising concerns about the ability of aquatic species to disperse between increasingly isolated habitat patches. To explore these dynamics, we used dragonflies and damselflies (Odonata) as a model taxon to examine how two principles of island ...

Wound Repair and Ca²⁺ Signalling Interplay: The Role of Ca²⁺ Channels in Skin

Cells
The process of wound healing is intricate and tightly controlled, involving a number of different cellular and molecular processes. Numerous cellular functions, especially those related to wound healing, depend critically on calcium ions (Ca2+).
