Waste-Derived Zeolite-P (GIS): Synthesis, Polymorphism, Characterization, and Adsorption Applications for Water Purification and Selective Gas Separation

Zeolite-P is a synthetic member of the gismondine (GIS) framework family and is intrinsically microporous, with intersecting eight-membered-ring channels. Mesoporosity reported for some Zeolite-P samples is therefore a secondary textural feature arising from interparticle voids,...

Synthesis, Phase Engineering and Optoelectronic Applications of Binary Arsenic Sulphide Thin Films from Orpiment to Dimorphite

Binary arsenic sulphide contains three thermodynamically stable compounds, orpiment (As2S3), realgar (As4S4) and dimorphite (As4S3), spanning a covalent layer network at the sulphur-rich end and discrete molecular cages at the arsenic-rich end. Thin-film research has concentrated...

Fluorescent Biofunctionalized Silver and Gold Nanoparticles: Bright Tools for Bioimaging Applications

Abstract The aim of this work is to evaluate different nanostructured systems based on noble metal nanoparticles suitable for drug delivery and release related to the treatment of multiple sclerosis. To this end, four different systems are thoroughly characterized from a chemical...

Photoluminescence and energy transfer in Tb3+-doped CeO2–Mn3O4 phosphor prepared by co-precipitation method

Terbium-doped CeO 2 –Mn 3 O 4 (CMO-Tb) phosphor was synthesized using co-precipitation and calcined at 500 °C. The material was characterized by X-ray diffraction (XRD), diffuse reflectance (DR), and photoluminescence (PL) spectroscopies. XRD analysis revealed that the main peaks...

A Comprehensive Review on Engineering Release at the Molecular Level: Role of Functional Groups in Polysaccharide-Based Drug Delivery

Stimuli-responsive drug-delivery systems (SRDDS) have transformed precision medicine by enabling spatiotemporal control over therapeutic release, significantly reducing off-target toxicity while enhancing efficacy at the disease site. Naturally occurring polysaccharides, such as...
