Cerium Nanoparticle‐Mediated Inhibition of the NSUN2/m5C Axis Suppresses Synovial Aggression in Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
A novel epitranscriptomic mechanism in rheumatoid arthritis is uncovered: NSUN2 promotes disease via m5C‐dependent stabilization of ICMT mRNA, fueling the migration and invasion of pathogenic RA FLS. Targeting this axis with engineered nanoparticles (Ce/SAA NPs) effectively inhibits disease progression, presenting a precise therapeutic strategy ...

Chemically Gradient Ordered Nanodomains Enable Large Tensile Ductility in Gigapascal Lightweight Refractory High‐Entropy Alloys

open access: yesAdvanced Science, EarlyView.
A high‐strength lightweight refractory high‐entropy alloy achieves extraordinary ductility owing to the introduction of coherent chemically gradient ordered nanodomains (CGONs). The CGONs not only serve as effective barriers to dislocation motion (strengthening) but also significantly promote dislocation nucleation and multiplication (ductilizing) upon

Standardless LA-ICP-MS fission-track dating in apatite: comparison with uranium thin film and LA-ICP-MS ζ-calibration

open access: yes
Abstract Over the past two decades, the fission-track community has sought to calibrate the ages with LA-ICP-MS. This technique has not only made thermochronology faster but also enabled the determination of U-Pb ages and the measurements of trace elements which support geological interpretation.

In Situ Reconstructed Crystalline–Amorphous CuNi Nanotubes Unifying Activity and Stability for Oxygen Evolution

open access: yesAdvanced Science, EarlyView.
Controlled electrochemical reconstruction creates a crystalline–amorphous CuNi nanotube that unifies catalytic activity and durability for alkaline oxygen evolution. The conductive metallic core and active amorphous oxide shell work synergistically to deliver low overpotential and exceptional stability exceeding 1000 h, offering a new strategy for ...

Time-of-flight ICP-MS laser ablation zircon geochronology: Assessment and comparison against quadrupole ICP-MS

open access: yes, 2020
This study presents U–Pb isotopic results from the mineral zircon measured by nanosecond laser ablation coupled to either a time-of-flight inductively coupled plasma mass spectrometer (ICP-MS), a quadrupole ICP-MS or both via a split stream arrangement ...

A comparative study of five reference materials and the Lombard meteorite for the determination of the platinum-group elements and gold by LA-ICP-MS

open access: yes, 2013
A range of independently characterised reference materials (RMs) for LA-ICP-MS, used for the determination of the platinum-group elements (PGE) and Au in a sulfide matrix, were analysed and compared: 8b, PGE-A, NiS-3, Po727-T1, Po724-T and the Lombard ...

EphB1‐Mediated Transient Blood‐Brain Barrier Opening Facilitates a Ferritin‐Based Nanotherapeutic for Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
We constructed a brain‐targeted AFn‐DPZ nanodrug delivery system and identified EphB1 as its receptor on the blood‐brain barrier (BBB). This system facilitates drug transport across the BBB and thereby ameliorates cognitive impairment in Alzheimer's disease.
