Abstract Advanced Mineral Identification and Characterisation System (AMICS) is based on energy dispersive X-ray spectroscopy (EDS) utilised in a scanning electron microscope (SEM). A specially designed software controls the sample positioning inside chamber, EDS spectra acquisition analysis, phase identification, results visualisation form of maps, graphs tables. can be conducted automatically for up to 28 mounted samples Hitachi SU3900 SEM with or without coating. Many options exist an experienced researcher influence analysis process: (i) extract spectrum each point determine chemical composition at this point, (ii) visualise mineral maps group phases characterise their interactions, (iii) particle geometry-chemistry relationship, (iv) conduct statistical spectra, define presence solute elements, distribution particles particular composition, (v) manually develop database unknown solid solutions. This paper briefly outlines AMICS features selected characterisation minerals, metal alloys, nanoparticle mixtures (MOFs ZIFs). The data methodology accuracy depth discussed.

Reactive oxygen species (ROS) are highly reactive, making them useful for environmental and health applications. Traditionally, photocatalysts piezocatalysts have been used to generate ROS, but their utilization is limited by various physical constraints. This study introduces metal-organic frameworks (MOFs) as modern thermocatalysts efficiently producing hydrogen peroxide (H 2 O ) from small temperature differences. Temperature fluctuations, abundant in daily life, offer tremendous potential practical thermocatalytic As proof of concept, MOF materials coated onto carbon fiber fabric (MOF@CFF) created a antibacterial filter. The compared three different MOFs (CuBDC, MOF-303, ZIF-8) with bismuth telluride (Bi Te 3 ), known material. ZIF-8 demonstrated superior H generation under low-temperature differences, achieving 96% activity through variation cycles. work advances thermoelectric applications MOFs, enabling real-time purification disinfection generation. findings open interdisciplinary avenues leveraging effects catalysis technologies.

Compressible liquids can be produced by dispersing nanoparticles containing hydrophobic pores as colloidal suspensions in water. Due to the water intrusion into nanopores under pressure, these compressible exhibit significantly greater compressibility than traditional liquids, lending them energy storage and absorption applications. Metal-organic frameworks (MOFs) such ZIF-8 have been proposed for this application due their large porosity, but physical chemical stability aqueous environments presents challenges, prone hydrolysis or separation from liquid phase. In work, concerns of used circumvented producing mesoporous a template-directed synthesis. The stability, compressibility, kinetics were compared between with without mesopores. ZIF-8, uniquely micropores hydrophilic mesopores, comparable that conventional has added benefit increased presence mesopores slightly reduces pressure accelerates cyclic vibrations repeated impact applications molecules reversibly intrude extrude micropores. This work inspire future endeavors on understanding developing porous sufficient practical uses.
