Summary: This article demonstrates for the first time that mechanochemically triggered free-radical polymerization allows solvent- and initiator-free syntheses of complex functional macro molecular architectures, namely stimuliresponsive microgels. The developed mechanochemical polymerization approach is applicable to a variety of monomers and allows synthesizing microgels with tunable chemical structure, variable size, controlled number of crosslinks and reactive functional end-groups.

Summary: A novel multicomponent perovskite was synthesized by substituting 5 cations in the A-site of BaTiO3 lattice. The compound underwent 5 hours of ball milling, followed by annealing at 800 degrees C for 2 hours, and then sintered at 1200 degrees C for 2 hours to form the cubic perovskite phase. The band gap of the compound was found to be 2.94 eV with a dielectric constant value of 270.

Summary: Photochemical reactions in reactors are limited by the penetration depth of light and require high dilutions. This study presents a method of UV photochemistry in a ball mill without bulk solvents. Triphenylene was synthesized with yields of 81% and 92% using the Mallory reaction and cyclodehydrochlorination (CDHC) respectively. The method was successfully scaled up to gram scale and demonstrated robustness for different substrates. Mechanosynthesis was also used to assemble nanographenes, providing a new tool for precise construction.

Summary: A one-pot, three-step protocol for the preparation of Grignard reagents from organobromides in a ball mill has been reported, followed by their reactions with CO2 or sodium methyl carbonate to provide aryl and alkyl carboxylic acids with yields up to 82%. The method stands out for its short reaction times and significantly reduced solvent amounts, with methoxy-substituted aryl bromides unexpectedly leading to major products being symmetric ketones.

Summary: Silver-substituted hydroxyapatites were prepared using a planetary ball mill. The samples were characterized using X-ray diffraction, FTIR spectroscopy, and simultaneous thermal analysis. It was found that single-phase substituted hydroxyapatites could be obtained with silver concentrations up to 1.5. Increasing the silver concentration resulted in an increase in crystal volume and unit-cell parameters. At a silver concentration of 2.0, an impurity phase of silver phosphate was detected. The thermal stability of the synthesized samples depended on the degree of substitution of calcium cations by silver cations.

Summary: Both experimental and modeling approaches were employed to examine the solid-state formation mechanisms and structural behavior of nanosized substituted hydroxyapatite powders, using different machine learning techniques such as artificial neural networks and genetic programming. The results showed that the modeling framework was effective in estimating structural features of HA-based bioceramics, with different models providing accurate predictions. The statistical assessments indicated good performance of the models in predicting crystallite size, with low Mean Squared Error values and high Correlation Coefficients.
