TiO:Eu nanoparticles with varying europium concentrations were successfully synthesized via a one-pot sol-gel approach using a molecular heterometallic single-source precursor (SSP) Eu-Ti. For comparison, nanomaterials with similar europium levels were also produced by impregnating europium salts onto the same TiO substrate. All the nanomaterials were thoroughly characterized using Eu elemental analysis, powder X-ray diffraction (XRD), scanning (SEM), transmission (TEM), scanning transmission electron microscopy (STEM), Brunauer-Emmett-Teller (BET) analysis, thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and photoluminescence (PL).

This paper presents the initial results of the synthesis of β-GaO luminescent ceramics via plasma gas-thermal spraying synthesis, where low-temperature plasma of an argon and nitrogen mixture was employed. A direct current electric arc generator of high-enthalpy plasma jet with a self-aligning arc length and an expanding channel of an output electrode served as a plasma source. The feedstock material consisted of a polydisperse powder of monocrystalline β-GaO with particle sizes ranging from 5 to 50 μm.

The cerebellum, a key target of ethanol's toxic effects, is associated with ataxia following alcohol consumption. However, the impact of ethanol on Purkinje cell (PC) mitochondria remains unclear. To investigate how ethanol administration affects mitochondrial dynamics in cerebellar Purkinje cells, we employed a transgenic mouse model expressing mitochondria-targeted yellow fluorescent protein in Purkinje cells (PC-mito-eYFP).

We report the design and development of a novel multifunctional nanostructure, RB-AuSiO_HSA-DOX, where tri-modal cancer treatment strategies-photothermal therapy (PTT), photodynamic therapy (PDT), chemotherapy-luminescent properties and targeting are integrated into the same scaffold. It consists of a gold core with optical and thermo-plasmonic properties and is covered by a silica shell entrapping a well-known photosensitizer and luminophore, Rose Bengal (RB). The nanoparticle surface was decorated with Human Serum Albumin (HSA) through a covalent conjugation to confer its targeting abilities and as a carrier of Doxorubicin (DOX), one of the most effective anticancer drugs in clinical chemotherapy.

In this work, non-layered two-dimensional α-MnSe nanosheets were transferred onto LaMnO (LMO) films to obtain a multifunctional heterostructure. The high crystal quality of the MnSe/LMO heterostructure was revealed by X-ray diffraction, Raman spectroscopy, and scanning electron microscopy measurements.
