Summary: The technique of pulsed laser ablation in liquid media was used to synthesize Palladium structures in nanoscale for antibacterial activity. The synthesized Pd NPs were characterized using FT-IR, XRD, TEM, and UV-Vis spectroscopy. The Pd NPs showed a face-centered cubic structure, with spherical shape and sizes ranging from a few nanometers to several tens of nanometers. The antibacterial activity of Pd NPs was higher against Gram-negative bacteria compared to Gram-positive bacteria.

Higher ablation duration of bimetallic nanoparticles led to improved photocatalytic performance in visible-light. Overall, laser ablation and irradiation in liquid technique proved effective for green synthesis of plasmonic hybrid nanomaterials.

Summary: Cu-doped ZnS nanoparticles were successfully prepared using pulsed laser ablation in a liquid medium, with X-ray diffraction confirming formation of wurtzite ZnS structures and photoluminescence revealing additional green emission due to the presence of Cu2+. The doped nanoparticles showed more efficient photocatalytic behavior compared to undoped ones, believed to be attributed to enhanced light absorption into the visible region or carriers based on the Cu2+ state.

Summary: The application of pulsed laser ablation technique for generating cerium-doped garnet nanoparticles in liquids is investigated. The morphological and optical properties of the obtained nanoparticles are demonstrated. The influence of single crystals of Gd3Al2.4Ga2.6O12:Ce3+, Lu3Al5O12:Ce3+, and Y3Al1.25Ga3.75O12:Ce3+ as well as the parameters of liquid media on the generation of garnet nanoparticles are experimentally studied using TEM and UV-Vis spectroscopy methods. The study reveals the relationship between the size, shape, and internal structure of the nanoparticles and the external laser ablation conditions and laser melting processes of NPs in the colloidal solutions. This work provides important information for the utilization of the generated nanoparticles as building blocks for structures with predetermined optical properties.

Summary: This study reports the synthesis of Au-decorated MCM-41 mesoporous nanoparticles using a laser-ablation technique. The number of Au attached to MCM-41 nanostructures was dependent on the amount of encapsulated Cationic surfactant. The chemical group and surface morphology of the prepared nanoparticles were analyzed and evaluated by FT-IR spectroscopy and TEM techniques. Raman spectroscopy showed that the prepared Au NPs facilitated strong Raman peaks and eight distinct Raman peaks were observed in the presence of Au NPs. This functionalized method using laser-ablation approach for mesoporous nanoparticles is of great importance in various applications.

Summary: The aim of this study was to obtain dense MgO refractories using two novel routes: TiO2 nanoparticles in brucite (R1) and TiO2 nanoparticles in caustic magnesia (R2). Results showed that MgO-TiO2 composites produced by R1 had higher densification rate (at least 3.29% greater density) and better mechanical properties (at least 20% better CCS) compared to those produced by R2. Therefore, starting from brucite (Mg(OH)2) to obtain MgO-TiO2 composites is a better alternative for producing materials with greater densification and better mechanical properties.

Summary: In this research, lead-free, all-inorganic, Cs3Bi2I9 perovskite-inspired films were developed using ultrasonic spray deposition at different substrate temperatures. These films demonstrate promising photodetection properties without any external bias or power consumption. The film's structural, morphological, optical, and electrical characteristics were analyzed in detail, and highly crystalline films with well-packed grains were obtained at temperatures below 325 degrees C. The Cs3Bi2I9 films showed direct band gaps of 1.8-2.1 eV and absorption coefficients of about 10^4 cm(-1). Photocurrent in the nanoampere range was observed in all the films under illumination. The films also remained chemically stable even after rapid thermal processing up to 500 degrees C. Additionally, self-powered photodetection using Ag/FTO/Cs3Bi2I9/C-Ag heterostructure was demonstrated under different illuminations, with the highest responsivity and detectivity obtained for the Cs3Bi2I9-based photodetector being 0.0051 mAW(-1) and 5.93 x 108 Jones (405 nm, 50 mW), respectively. The spray-deposited Cs3Bi2I9 films show great potential for self-powered devices, particularly in blue light detectors.

Summary: In this study, copper doped cerium oxide nanoparticles were synthesized using a phytosynthesis method, and their potential application in antibacterial activity was investigated. The presence of Cu2+ occupying Ce4+/Ce3+ sites and the redox conversion of Ce4+ to Ce3+ were found to enhance the antibacterial activity of the doped nanoparticles. The characterization of the nanoparticles was done using various techniques such as X-ray diffraction, infrared spectroscopy, Raman spectroscopy, and energy-dispersive analysis of X-ray spectroscopy. The results showed that the addition of copper resulted in smaller particle sizes and the presence of different phases in the nanoparticles.

Summary: The aim of this study was to synthesize SiO2 nanoparticles using Tequila as a green chemistry, which is a novel approach. Tequila was used as a capping, reducing, surfactant, and stabilizer agent in a mixture of silicon tetraacetate, deionized water, acetone, and sodium hydroxide. The nanoparticles were characterized using XRD, UV-Visible spectrophotometer, and TEM, which revealed an amorphous phase of SiO2 nanoparticles with a size of 20 +/- 30 nm and an absorption peak at 260 nm. Tequila was found to contain more than 175 constituents, with 2-methyl-1-butanol and 3-methyl-1-butanol being the most common. These higher alcohols were found to act as good dispersers, increasing nucleation sites and reducing grain growth. This study demonstrated a green and cost-effective method for synthesizing SiO2 NPs using Tequila in a novel and original way.

Summary: Concrete is the most commonly used construction material, but the production of Ordinary Portland Cement contributes to CO2 emissions. Geopolymers are emerging as an alternative building material that does not require Portland Cement. This study investigated the effects of adding mu-limestone to mixtures of blast-furnace slag and fly ash activated with sodium hydroxide. The addition of mu-limestone improved the compressive strength and microstructural properties, making it a promising and cost-effective alternative for low-molarity alkaline cement.
