The chemical reactivity of clay minerals is enhanced during intensive grinding, due to mechano-chemical dehydroxylation and mechanically-induced amorphisation. The most widely used grinding apparatus for laboratory-scale studies is a planetary ball mill. It is still largely unknown whether activation efficacy is critically dependent on any individual milling parameter, or whether trade-offs are possible between different parameters. In this study a first principles approach, previously applied to alloy amorphisation, is adopted to estimate the energy of an individual collision event and the total milling input energy. Using a combination of primary data generated through experiments and secondary data from literature, a set of nearly 100 datapoints was analysed. Rapid increases in chemical reactivity were generally observed for <100 kJ g−1 of modelled milling energy input, with a plateau beyond this value. The relationship between chemical reactivity and modelled energy input was well fitted by an exponential type function. For the same modelled milling energy input, a higher gain in chemical reactivity was achieved for the 1 : 1 clay minerals compared to the 2 : 1 clay minerals or mixtures of different clay minerals. No strong trends were observed with individual collision energy, with no clear evidence for the existence of a threshold collision energy. The modelled milling input energy was more effective for predicting reactivity increase than measured energy consumption by the mill. Within the ranges tested, increasing ball : powder ratio or rotation speed seemed to be more energetically efficient at increasing reactivity, compared to increasing milling duration. Results from this study can also aid in selection of milling equipment for scaling up this process.","PeriodicalId":101140,"journal":{"name":"RSC Mechanochemistry","volume":" 2","pages":" 201-212"},"PeriodicalIF":0.0,"publicationDate":"2025-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/mr/d5mr00088b?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147375087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their production depends on critical raw materials, such as lithium, nickel, and cobalt. When reaching the end of their life, spent batteries are regarded as toxic waste, underscoring the need for efficient and inexpensive recycling technologies to enable a circular economy. Current recycling technologies exhibit issues, such as wastewater generation and high consumption of energy and chemicals. While the focus has been on the recovery of valuable transition metals, lithium is often not recovered. In this study, we present a deeper investigation of the solvent-free mechanochemical reduction of LiCoO2 with Al. The combined analysis using XRD, SEM and EDX, together with the observation of a characteristic temperature and pressure profile, proved the reaction to proceed via a mechanically induced self-propagating reaction pathway. A spike in the pressure, detected by an internal sensor in the milling jar, was used to determine the length of the activation phase, which enables a kinematic analysis and the systematic study of milling parameters. Furthermore, the presence of graphite was found to increase the activation time and with a 20% weight fraction, the self-propagating behavior can be suppressed. This research provides important information regarding the application of this process on a real black mass or on a larger scale.","PeriodicalId":101140,"journal":{"name":"RSC Mechanochemistry","volume":" 2","pages":" 243-253"},"PeriodicalIF":0.0,"publicationDate":"2025-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/mr/d5mr00092k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147375141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this conventional approach is associated with substantial solvent consumption, waste production, and environmental and safety concerns, while also necessitating protracted reaction times. In recent years, there has been an increase in the study of various mechanochemical methods, with the flow-through mechanochemical approach via reactive extrusion (REX) emerging as one of the most promising alternatives. This process employs screws (single, twin or multiple) to generate mechanical energy (shear, compression and friction) to drive chemical reactions, offering precise control over temperature, mixing and residence time. Typically, REX is performed with minimal or no solvents, which significantly reduces its environmental impact. Furthermore, it ensures shorter reaction times and higher yields. In this review, a comprehensive analysis is conducted on the role of screw configuration, temperature control, and residence time in optimising the outcomes of various reaction types.","PeriodicalId":101140,"journal":{"name":"RSC Mechanochemistry","volume":" 2","pages":" 144-160"},"PeriodicalIF":0.0,"publicationDate":"2025-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/mr/d5mr00097a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147375083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ligand exchange reactions performed under grinding conditions showed the conversion of the dpe-containing polymers into bipy-containing polymers, whereas the reverse reactions proved unfeasible. A computational rationale for the observed reactivity is provided. The dimensionality growth of the dpe-containing 1D-coordination polymers into a three-dimensional pillared metal–organic framework was achieved by reaction with terephthalic acid. The same 3D-MOF was also obtained by a one-pot procedure, involving dpe, Zn(OAc)2·2H2O and terephthalic acid simultaneously ground in the presence of a small aliquot of N,N-dimethylformamide. All the reactions occurred in high yields affording pure products with a favorable environmental profile, as evidenced by the environmental factor (EF) and reaction mass efficiency (RME) calculated for selective reactions. This work highlights how mechanochemistry not only allows the efficient synthesis of coordination polymers but also their post-synthetic modifications by environmentally benign protocols.","PeriodicalId":101140,"journal":{"name":"RSC Mechanochemistry","volume":" 2","pages":" 280-292"},"PeriodicalIF":0.0,"publicationDate":"2025-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/mr/d5mr00106d?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147375145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
