Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

A Discussion on Genetic Mechanism of the Kuerqis Iron Deposit in Fuyun County, Xinjiang

open access: yesYankuang ceshi, 2013
The large iron deposits in the southern margin of Altay had been studied systematically, but researches on some small Fe-rich type such as Kuerqis iron deposit are still obviously insufficient.

Stabilization of Cu Species in UiO‐66 Metal–Organic Framework for CO2‐to‐Methanol: Insights From Operando X‐ray and Electron Microscopy Studies

open access: yesSmall, EarlyView.
This study reveals how a zirconium‐based metal–organic framework (UiO‐66) stabilizes copper species during CO2 hydrogenation to methanol. Operando X‐ray spectroscopy, electron microscopy, and theory show that zinc promotes highly dispersed copper and suppresses particle growth, while the framework dynamically responds to reaction intermediates.

A Modular Core–Shell Nanoparticle Platform for Dual‐Modal MRI–Luminescence With High Relaxivity

open access: yesSmall, EarlyView.
A modular core–shell nanoparticle platform is presented that combines high‐relaxivity magnetic resonance imaging (MRI) and long‐lived luminescence within a single, well‐defined architecture. Spatially controlled gadolinium(III) and terbium(III) complexes deliver reproducible dual‐modal agents with benchmark MRI performance.

Facile Sprayed and Electro‐Activated Ultra‐Low Pt Loading Catalyst for Hydrogen Evolution Reaction and PEM Water Electrolysis

open access: yesSmall, EarlyView.
A spray‐coating‐assisted electrochemical reduction strategy enables uniformly dispersed 2–3 nm Pt nanoparticles at an ultra‐low loading of 0.0178 mgPt cm−2 on rough gas diffusion electrode surfaces. The resulting architecture delivers exceptional hydrogen evolution activity and PEM water electrolysis performance comparable to commercial Pt/C while ...

Impact of Positively Charged Backbone Modifications on the Properties of Spherical Nucleic Acids

open access: yesSmall, EarlyView.
A synthesis of spherical nucleic acids (SNAs) featuring cationic backbone modifications is presented, together with an analysis of their emerging properties. Introducing positively charged guanidinium groups near the SNA surface enhances cellular uptake and offers a pathway toward more precise control over SNA internalization.
