In Situ Spectroscopic Studies on the Mechanism of CO2 Adsorption and Photocurrent Applications over g‐C3N5

open access: yesSmall Structures, EarlyView.
In‐situ Fourier transform infrared spectroscopy (FTIR) and X‐ray photoelectron spectroscopy (XPS) techniques are used for the first time to investigate the nature of interaction between CO2 and g‐C3N5, which is prepared by using aminotriazole. The in‐situ FTIR, pre‐ and post‐XPS studies, high‐pressure CO2 adsorption reveal only physisorption of CO2 ...

Methanobactin rapidly facilitates biliary copper excretion in a Wilson disease rat model visualised by 64Cu PET/MRI

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Methanobactins are peptides with high copper affinity and potential to treat Wilson disease. We examined how two methanobactins (ARBM101 and MB‐OB3b) affected copper handling in the LPP Atp7b−/− Wilson disease rat model, compared to penicillamine or saline, by 64Cu positron emission tomography/magnetic resonance imaging ...

In Situ Impact of Waste Polyethylene (PE) Films on Soil Quality and Plant Growth in Agricultural Soil

open access: yesLand Degradation &Development, Volume 36, Issue 14, Page 5054-5065, 30 August 2025.
ABSTRACT Plastic films have accumulated in soil ecosystems over decades of agricultural activities. These films potentially disrupt the soil structure, hinder nutrient cycling, and deteriorate soil quality. However, there is still a substantial knowledge gap in understanding how real‐world waste polyethylene films (WPEFs), with varied shapes and sizes,

Achieving Multimodal and Multicolor Luminescence in LaAlO3:Pr3+, Gd3+ via Trap Engineering and Energy Transfer

open access: yesChemPhysChem, Volume 26, Issue 16, August 23, 2025.
A single LaAlO3:Pr3+, Gd3+ phosphor exhibits penta‐modal luminescence (down‐conversion luminescence, up‐conversion luminescence, persistent luminescence, optically stimulated luminescence, and thermally stimulated luminescence) across ultraviolet–visible–near‐infrared regions, enabled by distinct traps (0.69–1.15 eV) and defect engineering, with ...

Preclinical comparison of four [18F, natGa]rhPSMA-7 isomers: influence of the stereoconfiguration on pharmacokinetics

open access: yesEJNMMI Research, 2020
Introduction Radiohybrid (rh) ligands, a novel class of prostate-specific membrane antigen (PSMA)-targeted radiopharmaceuticals, can be labeled either with [18F]fluorine via isotopic exchange or with radiometals (such as [68Ga]Gallium, [177Lu]Lutetium ...

A Water Stable U(IV) Complex Based on a Macrocyclic Ligand Displaying NIR Emission

open access: yesChemistry – A European Journal, Volume 31, Issue 45, August 13, 2025.
A water‐stable U(IV) complex is obtained by coordination of U(IV) with a nonadentate macrocyclic ligand based on a triazacyclononane platform. The U(IV) cation is fully protected from coordination of water molecules, and upon excitation into the UV‐Visible region, the complex displays an unprecedented NIR emission from U(IV). Abstract Complexation of U(

Synthesis and Radiolabelling of DOTA-Linked Glutamine Analogues with 67,68Ga as Markers for Increased Glutamine Metabolism in Tumour Cells

open access: yesMolecules, 2013
DOTA-linked glutamine analogues with a C6- alkyl and polyethyleneglycol (PEG) chain between the chelating group and the L-glutamine moiety were synthesised and labelled with 67,68Ga using established methods.

High precision half-life measurement of the extinct radio-lanthanide Dysprosium-154

open access: yesScientific Reports, 2022
Sixty years after the discovery of 154Dy, the half-life of this pure alpha-emitter was re-measured. 154Dy was radiochemically separated from proton-irradiated tantalum samples. Sector field- and multicollector-inductively coupled plasma mass spectrometry
