Summary: The water resources of our planet are under significant pressure due to human activities such as industry, agriculture, urbanization, and deforestation. Detecting pollutants in water is the first step in their removal, and this requires the use of various instrumentation techniques or sensors. Among the different types of sensors, gold and silver nanoparticle-based colorimetric/plasmonic nano-sensors are particularly significant due to their simplicity and low cost. These sensors are based on the principle of surface plasmon resonance (SPR), which is an optical phenomenon dependent on the characteristics of nanoparticles. Noble metal nanoparticles, such as gold and silver, are widely used in colorimetric sensing applications because their SPR absorbance lies in the visible spectrum, resulting in unique colors. They are also easy to synthesize, functionalize, biocompatible, and stable. In this detection technique, the presence of a pollutant is revealed by a distinct visual color change and can be quantified using a UV-Visible Spectrophotometer. The review aims to address the gap in scientific literature by exploring the application of green-synthesized silver and gold nanoparticles in colorimetric nano-sensors, thereby assisting researchers in this field.

Summary: Chemical Vapor Deposition (CVD) is a process where a solid is formed on a substrate through chemical reactions in the vapor phase. It allows for the coating of various materials, such as ceramic nanocomposites, dielectrics, and single crystalline silicon, onto different substrates. The design of a CVD system is influenced by factors like substrate dimensions, temperature, chemical composition, deposition process, chamber temperature, material purity, and production economics. Surface reaction kinetics, mass transfer reactions, and desorption reactions are involved in the CVD process. Thermodynamically, CVD requires high temperatures and low pressures. Kinetic control is used at low temperatures, while diffusion control is applied at high temperatures. Coatings in CVD are typically deposited at temperatures ranging from 900 to 1400 degrees Celsius. By controlling chamber temperature, precursor purity, and precursor flow rate, it is possible to partially control deposition rate and microstructure of ceramic coatings during the CVD process.

Summary: The performance of a nanocomposite adsorbent, comprised of nickel ferrite, zinc oxide, and alpha alumina nanoparticles on a graphene oxide substrate, was investigated for the removal of malachite green. The composites were characterized using various spectroscopy and imaging techniques, confirming the presence of particles and preservation of particle structure in COM4. The adsorption efficiency was examined under various conditions, showing maximum adsorption using the Langmuir model at pH 7 and ambient temperature. The adsorption mechanism was proposed to involve surface functional groups, electrostatic interactions, H-bonding, 7C-7C interactions, and permeation of dye molecules into the pores of the adsorbent. The adsorbent exhibited good performance for multiple cycles after washing with ethanol.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.
