Summary: The synthesis of pure ZnO with nominal Mn and Co co-doping was conducted using a cost-effective wet chemical route to explore their dielectric response. Structural and morphological analysis showed the influence of Mn and Co doping on crystal structure and particle morphology in ZnO. The higher dielectric constant observed was attributed to the presence of oxygen vacancies generated during the process.

Summary: In this study, highly crystalline bi-functional manganese-doped zinc silicate (Mn-doped Zn2SiO4) nanostructures were synthesized using a low-cost sol-gel route followed by solid state reaction method. Structural and morphological characterizations of the doped nanostructures were conducted using X-ray diffraction and high-resolution transmission electron microscopy (HR-TEM) techniques. Photoluminescence (PL) spectra showed strong green emission at 521 nm under 259 nm excitation wavelengths, with the intensity increasing with increasing Mn-doping concentration. The magnetic properties of the doped nanostructures were also investigated. These findings open up new possibilities for the application of Mn-doped Zn2SiO4 nanostructures in magneto-optical and spintronic devices.

Summary: In this study, thin films of lanthanide oxysulfide were developed that are compatible with flexible substrates and retain the robustness advantages of inorganic compounds. The films, made using a low-temperature dip coating method, maintained the optical quality of the materials. The thickness of the films could be adjusted in a wide range, and thermal treatment was optimized to remove organic ligands while preserving the integrity of the nanoparticles.

Summary: The sol-gel method was used to produce dilute magnetic semiconductor nanoparticles, and FTIR and electrical conductivity tests were employed to investigate their structural and electrical properties. The incorporation of Mn or Cr dopants into the ZnO framework structure may lead to structural stress and defects, resulting in an increase in conductivity values as doping concentrations decrease.

Summary: The study investigates the influence of oxygen octahedra distortion on the magnetic and magnetoelectric properties of Bi1-xErxFe1-yZryO3 (x = 0, .05, .1, y = .02, .05) polycrystalline nanoparticles synthesized by sol-gel route. The doping of Er (via Bi site) and Zr (via Fe site) ions in BiFeO3 results in variations in the Fe-O-Fe bond angle, tilt angle of oxygen octahedra, and canting angle of spiral spin arrangement. This leads to changes in the magnetization, number of electrons per unit cell, coherently diffracting domains, and magnetoelectric coupling coefficient. Among the samples, Bi0.95Er0.05Fe0.98Zr0.02O3 exhibits enhanced magnetic and magnetoelectric behaviors.

Summary: In this study, MnCo2S4 nanosheet catalyst was successfully synthesized and found to exhibit superior performance in hydrogen evolution. Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
