Summary: Spherical Si@Si3N4 granules were successfully synthesized using in situ combustion synthesis. The granules have a dense internal structure without cracks, and the Si3N4 grains on the surface are well-bonded without the use of binders. The synthesized granules show great potential for heat dissipation in electronic devices.

Summary: The CuFe2O4/g-C3N4 nanocomposite showed better catalytic decomposition effects on ammonium perchlorate (AP) and 1,3,5-trinitroperhydro-1,3,5-triazine (RDX) compared to bulk g-C3N4 and related GO-based catalysts. The composite can lower the decomposition temperatures, change the decomposition processes, and present a more effective catalytic decomposition on AP and RDX.

Summary: NiCo/(Ni,Co)O/(Ni,Co)Fe2O4 composites were prepared in-situ by solution combustion method. The presence of Ni(1-x)Co(x) phase instead of pure Ni and Co phases was confirmed by magnetic properties. The combusted composites exhibited spongy microstructure without any special morphology for various phases.

Summary: alpha-Si3N4 powder was synthesized by combustion synthesis method, and the propagation characteristics of the combustion wave were investigated using thermocouple temperature measurement and resistance-combustion wave displacement response device. The results showed a narrow region of combustion reaction with a maximum temperature gradient of 180 degrees C/mm at the combustion front. The use of the resistance-combustion wave displacement response device allowed for in situ measurement of the combustion wave propagation process, and the test results provided quantitative data on the Si-N-2 discrete combustion characteristics for the first time.

Summary: A series of Tb3+-doped Y1-xAl3(BO3)4 phosphors were synthesized and characterized in this study. The synthesized phosphors exhibited good crystallinity and crystal structure, and showed a green main emission peak at 543 nm under excitation. The photoluminescence intensity of the phosphors increased with increasing Tb3+ ion concentration up to a certain threshold, and then exhibited concentration quenching. Moreover, the study found the activation energies for thermal quenching at different wavelengths.

Summary: Ni-doped SnO2 powder samples were synthesized and characterized by various techniques, showing nanocrystalline rutile tetragonal structure, decreased bandgap with increasing Ni concentration, and confirmation of room temperature ferromagnetism. The incorporation of Ni ions into the lattice of pure SnO2 was confirmed through shifts in vibrational peaks observed in FTIR spectra.

Summary: Plutonium dioxide synthesis is an important step in fuel reprocessing, and the solution combustion synthesis method (SCS) has advantages in fuel preparation. This study reports the synthesis of PuO2 by SCS with citric acid for the first time. An optimal citric acid to plutonium ratio (CA/Pu=1.1) was determined for PuO2 synthesis, resulting in oxides with characteristic morphologies of SCS.

Summary: This study focuses on developing solution-combustion-processed hafnium-doped In2O3 thin films and evaluating the effects of different annealing parameters on the properties of transparent conducting oxides. The optimized TCOs exhibit high transparency, low resistivity, and good carrier mobility, bringing solution-based TCOs a step closer to low-cost optoelectronic applications.

Summary: The research aims to use calcination to produce nano calcium oxide (CaO) additives for fuel. Spectrum investigations confirmed the synthesis of nano particles using X-ray Diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). The qualities of the fuel were evaluated based on ASTM criteria, and the combustion investigation in an engine found improved performance with CaO nano additives. The study concludes that micro CaO particles can potentially be used to enhance the combustion characteristics of engines powered by biodiesel blends.

Summary: This paper describes the synthesis of 4-O-alkyl analogues of N-acetylneuraminic acid (Neu5Ac) and the scope of the reaction. It demonstrates that activated alkyl halides and sulfonates, as well as primary alkyl iodides, can give products in useful yields. The utility of the methodology is exemplified using a specific example of synthesizing a 4-O-alkyl DANA analogue. These results expand the toolbox of Neu5Ac chemistry and have value in drug discovery and the study of Neu5Ac lectins biology.

Summary: Non-thermal plasma processing is used to modify the surface of magnesium nanoparticles with silicon to enhance interfacial reactions and ignition pathways. This results in a nanostructured thermite system at the single particle level, reducing the ignition temperature and combustion kinetics. The intermetallic reaction within the magnesium/silicon system reduces the ignition threshold significantly, from approximately 740°C to approximately 520°C for particles coated via the in-flight plasma process.

Summary: CuxFe3-xO4 nanoparticles with varying copper and iron ratios were synthesized using the one-step solution combustion synthesis method. The effects of different synthesis conditions, including the presence of air, on the final product were investigated. Various analysis techniques confirmed the formation and structure of the nanopowders. The use of a closed system during synthesis yielded efficient results with reduced occurrence of secondary phase formation.
