2D van der Waals System Integrated with Targeting Radio‐Diagnostic and Imaging Functions

Small, EarlyView.
Layered double hydroxide (LDH) nanoplates were engineered for tumor‐targeted imaging and therapy. By exploiting folate receptor (FR) expression levels, the system achieves selective tumor accumulation and high‐resolution dual PET/fluorescence (PET/FL) imaging.

Assessment of Soil Erosion Over Six Decades in a Long‐Term Experiment Using Fallout 137Cs and RUSLE: A South American Case Study

Land Degradation &Development, Volume 37, Issue 13, Page 9038-9052, 15 August 2026.
ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...

Study of the detection efficiency of a surface contamination monitor according to the distance and the surface emission rate

Saúde & Tecnologia, 2015
Introduction – A radioactive contamination needs to be quantified in case it eventually occurs. Therefore it is necessary to ensure that the operating conditions of a surface contamination monitor are characterized by determining its detection efficiency.

Supramolecular Coordination Platforms for Smart Theranostics: Leveraging the Dynamic Molecular Networks of Metal–Polyphenol Assemblies

Aggregate, Volume 7, Issue 7, July 2026.
In this review, we summarize the recent developments of metal–polyphenol networks (MPNs) as a highly versatile and functionally integrated supramolecular assembly platform. We also discuss their pivotal role in steering biomedical materials away from conventional single‐function designs and toward intelligent, unified diagnostic and therapeutic ...
