Special Issue Information

Dear Colleagues,

Metal nanoparticles continue to generate significant interest due to their unique, size-dependent properties and broad applicability in catalysis, energy conversion, medicine, electronics, civil engineering, and environmental technologies. A deep understanding and precise control of their behavior at the molecular level are essential for enhancing their functionality and enabling next-generation applications.

This Special Issue aims to highlight recent progress in the synthesis, structural characterization, and functional properties of metal nanoparticles, with particular emphasis on molecular-level processes and mechanisms.

We invite interdisciplinary contributions from researchers in materials science, chemistry, physics, and nanotechnology that explore fundamental aspects of nanoparticle behavior as a foundation for innovative solutions. Topics of interest include, but are not limited to, mono- and bimetallic systems, alloyed nanoparticles, nanoclusters, functionalized surfaces, and hybrid nanomaterials. The overarching goal is to demonstrate how molecular-level insights can drive progress in the design, optimization, and real-world application of metal nanoparticles across diverse scientific and technological domains.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Thallium is a soft metal with a grey or silvery hue. It commonly occurs in two oxidation states in chemical compounds: Tl+ and Tl3+. Thermodynamically, Tl+ is significantly more stable and typically represents the dominant form of thallium in environmental systems. However, in this chemical form, thallium remains highly toxic. This study focuses on the modification of a glassy carbon electrode (GCE) with silver nanostructures stabilised by potato starch derivatives. The modified electrode (GCE/AgNPs-E1451) was used for the determination of trace amounts of thallium ions using anodic stripping voltammetry. Emphasis was placed on assessing the effect of surface modification on key electrochemical performance parameters of the electrode. Measurements were carried out in a base electrolyte (EDTA) and in a real soil sample collected from Bali. The stripping peak current of thallium exhibited linearity over the concentration range from 19 to 410 ppb (9.31 × 10−8 to 2.009 × 10−6 mol/dm3). The calculated limit of detection (LOD) was 18.8 ppb (9.21 × 10−8 mol/dm3), while the limit of quantification (LOQ), corresponded to 56.4 ppb (2.76 × 10−7 mol/dm3). The GCE/AgNPs-E1451 electrode demonstrates several significant advantages, including a wide detection range, reduced analysis time due to the elimination of time-consuming pre-concentration steps, and non-toxic operation compared to mercury-based electrodes.
