Bridging and Rewiring Mechanisms in the Deconstruction of the Functional Architecture of Fish Assemblages in the Upper Paraná River Basin by Non‐Native Species

open access: yesEcology of Freshwater Fish, Volume 36, Issue 1, January 2027.
ABSTRACT Freshwater ecosystems harbour nearly half of all known fish species yet rank among the most threatened on the planet, with biological invasion operating as one of the primary functional destabilizers in systems where dam cascades have already dismantled natural biogeographical barriers. In the Upper Paraná River basin, which supports high fish

Clinical Laboratory Innovations: Nanoscale Detection of Chloramphenicol Using Nanomaterial Biosensors

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
Nanosensor schematic functionalized with specific bioreceptors that produce electrochemical signals upon Chloramphenicol binding. Resulting voltammetric readouts (differential pulse, square‐wave, and cyclic voltammetry) are analyzed to identify and quantify Chloramphenicol.

ONLINE NUCLEAR ORIENTATION OF CESIUM ISOTOPES AND THE MAGNETIC-MOMENT OF CS-118M

open access: yes, 2016
Cesium isotopes have been oriented in iron, following on-line implantation at temperatures down to 8 mK. Analysis of results on transitions in the decay of Csm119, Csg120, and Csm121 yields the hyperfine field Bhf(CsFe)=(+)40.8(7) T. A repeated sequence of short pulse implantation followed by relaxation has been used to measure the Korringa constant ...

Recent Advances in Reversed‐Phase Liquid Chromatography for Therapeutic Oligonucleotide and Conjugate Characterization: From Ion‐Pairing to Green Analytical Approaches

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Therapeutic oligonucleotides (ONs) have rapidly emerged as a novel class of treatments in the pharmaceutical industry, with over 25 medicines approved in the past decade. Ion‐pair reversed‐phase liquid chromatography coupled with mass spectrometry (IP‐RPLC‐MS) is widely used method for ON characterization.

Study of nuclear properties of cesium and francium isotopes by atomic spectroscopy

open access: yes, 1986
Ce travail porte sur l'étude d'isotopes de cesium (118,146Cs) et de francium (207-213Fr et 220-228Fr) par spectroscopie atomique hyperfine et sur l'interprétation de ces résultats du point de vue nucléaire. Les grandeurs nucléaires mesurées sont : le spin, le moment magnétique, le moment quadrupolaire électrique et le rayon carré moyen de charge.

Multi‐Vendor and Multi‐Site Characterization of 13C Coils for Clinical Studies

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 6, Page 2885-2893, December 2026.
ABSTRACT Purpose Due to the inherently low signal‐to‐noise ratio (SNR) domain for 13C imaging, optimal coil performance is essential to maximize data quality. Quality control (QC) for 13C coils employed in magnetic resonance spectroscopy (MRS) is of paramount importance.
