Solvent-free techniques have gained considerable attention in recent years due to their environmental advantages and potential enable chemical reactivities beyond the reach of traditional solution-based methods. Mechanochemistry has emerged as a groundbreaking approach drive sustainable processes. Despite its promise, some challenges still need be explored, including overlooked issue material leaching during grinding, phenomenon which components from milling media or reaction vessels, such stainless steel, unintentionally alter outcomes. This study investigates role metal reducing arylnitrosamines by using poorly soluble solid reagent, thiourea dioxide (TDO), focusing on steel vessels. By comparing conventional mechanochemical methods with innovative solvent-free vibratory techniques, we assess extent contamination impact efficiency. These findings provide new insights into how influences processes offer valuable guidance for optimizing these forward-looking green methodologies.

Polymer corrosion inhibitors are reported to form dense films on carbon steel surfaces, and their thermostability enables survival in harsh downhole environments. In this paper, PEG-OTs was synthesized by mechanochemistry using ball mill grafting tosyl PEG. Using solvent-free green chemistry, non-toxic PEG with various molecular weights (600, 2000, 10,000 g/mol) were prepared used as inhibitors. The inhibition performance of 5 × 10−3 mol/L Q235 0.5 M HCl solution investigated static weight-loss, electrochemical impedance spectroscopy, polarization curves, SEM, contact angle measurements. results show that, after modification, has an elevated effect compared A maximum 90% efficiency achieved weight-loss. morphology study shows that a film formed protect steel. Thanks polymeric structure, higher weight leads better inhibition.

In this contribution, we apply our newly developed ball-milling operando platform, which combines Raman spectroscopy and thermal (IR) imaging, as well acoustic high-speed optical video recordings, to the synthesis transformation of citric acid–isonicotinamide (1:2) cocrystal polymorphs in transparent PMMA jars. Particularly, demonstrate how Raman, temperature, acoustic, data are complementary enable detection connection chemical physical events happening during a time-resolved manner. Importantly, show that formation three can be detected through analyses solely. Even more impressively, meticulous sound allowed subtle polymorphic transitions perceived mode when was not conclusive enough. Such changes signatures greatly linked beads' motions milling jar. A new analysis methodology recordings is proposed combination energetic statistical approaches simplifies for potential users. The interpretation signals further validated thanks videos recorded synchronization with all other techniques. Finally, broaden opaque stainless-steel jars, showing relevance method following transformations cocrystals, pure substances, any type
