Abstract This study investigates the mechanochemical synthesis of Yttrium Oxide (Y₂O₃) and Hydrogen Peroxide (H₂O₂) via planetary ball milling, with a focus on catalytic effect nickel. Hydride (YH₃) was milled under hydrogen atmosphere, both without nickel catalyst, to assess influence various process parameters such as milling time, pressure, catalyst presence phase transformation, crystallite size, particle morphology, size distribution. X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), laser analysis (PSA) were used characterize samples. Results show that catalysis significantly enhances reaction kinetics, reduces promotes uniform morphology compared non-catalyzed Catalyzed samples exhibited faster transformation from YH₃ Y₂O₃, reduction 11.0 nm near-complete formation Y₂O₃ H₂O₂. These findings demonstrate nickel-catalyzed offers an efficient scalable route for synthesis, potential applications in catalysis, storage, environmental remediation. Further research optimizing conditions exploring other catalysts is recommended.

Abstract The rising prospects of mechanochemically assisted syntheses hold promise for both academia and industry, yet they face challenges in understanding and, therefore, anticipating respective reaction kinetics. Particularly, dependencies based on variations milling equipment remain little understood globally overlooked. This study aims to address this issue by identifying critical parameters through kinematic models, facilitating the reproducibility mechanochemical reactions across most prominent mills laboratory settings, namely planetary mixer mills. Through a series selected experiments replicating major classes organic, organometallic, transition metal‐catalyzed, inorganic from literature, we rationalize independence kinetics when accumulated energy criterion is met. As step forward facilitate practicability our findings, provide freely accessible online tool [†] that allows calculation different Our work advances current mechanochemistry lays foundation future rational exploration rapidly evolving field.

Abstract Our research has demonstrated that mechanochemical activation is more effective with solid reagents. We have showcased the practicality of Bertagnini's salts, also called aldehyde‐bisulfite adducts, which are crystalline, simplifying preparation and storage. These salts stable substitutes for liquid aldehydes ketones been employed in reductive amination, synthesizing aza‐heterocycles hydrazones within mechanochemistry. The technique‘s effectiveness broadens substrate scopes, simplifies purification, reduces reaction times, yields desired products ranging from 38–91%. Additionally, thermal stability bisulfite adducts confirmed through TGA (Thermogravimetric analysis) analysis.

With the rapid increase in temperatures around planet, need to develop efficient means reduce CO2 emissions has become one of greatest challenges scientific community. Many different strategies are being studied worldwide, which consists trapping gas porous materials, either for its short- or long-term capture and storage, re-use production value-added compounds. Yet, further development such systems, there is a real fully understand their structure properties, including at molecular-level following physisorption and/or chemisorption (which can lead various species, carbonate bicarbonate ions). In this context, 17O NMR naturally appears as analytical tool choice, because exquisite sensitivity probe subtle differences oxygen bonding environments.
