Summary: Efforts to generate organomanganese reagents under ball-milling conditions have led to the serendipitous discovery that manganese metal can mediate the reductive dimerization of arylidene malonates. This unique reactivity can also be translated to solution, but pre-milling of the manganese is required for this transformation.

Summary: This study investigates the differences in composition of acid phosphate, carbonate, hydroxyl, iron, and magnesium content between pigmented incisor enamel and unpigmented molar enamel of Sprague Dawley rats. The results reveal that iron-rich pigmented enamel has higher mineral crystallinity, higher levels of acid phosphate and hydroxyl, and no presence of iron oxides or oxy(hydroxides). These findings provide new insights into enamel biomineralization and the functional differences of ameloblasts between incisors and molars in rodents.

Summary: This study aimed to improve the productivity of nanobiochar (NBC) through high-energy ball milling, finding that using grinding media with different sizes of steel balls was more effective. Results showed that 30 minutes of ball milling could produce NBC particles around 95 nm, while 60 minutes were sufficient to produce 75 nm NBC particles with high thermal stability.

Summary: HEBM powder processing promotes better phase distribution and crystallite size in HA/BT composite coatings, resulting in improved bonding strength and failure type. Additionally, HEBM treatment leads to slightly greater crystal phase stability and crystal shrinkage, as well as enhances nanomechanical properties of the coatings.

Summary: Research has shown that pure SnSe polycrystalline materials prepared by high-energy ball milling exhibit a high ZT value at 873K. The decrease in lattice thermal conductivity and increase in Sn vacancies induced by high-energy ball milling contribute to the improved conductivity of the materials. The absence of oxidation during the ball milling process in a closed argon-filled environment ensures the purity of the SnSe polycrystalline materials, leading to their high ZT value.

Summary: Phosphorus recovery from water hyacinth shows potential for alleviating future P supply shortage. Thermal treatment of calcium and P-rich water hyacinth at different temperatures results in the formation of hydroxyapatite and other Ca-rich phases, which can be utilized as fertilizer for slow release of P in aqueous solutions and for soil neutralization to support crop growth.

Summary: This study reports the process to fabricate powder of high-entropy carbide (TiTaNbZrHf)C using two-step high-energy ball milling. The high-entropy carbide phase was obtained through milling metallic precursors and carbon, showing thermal stability up to 1200 degrees C. The process includes the conversion of metallic precursors, the reaction diffusion of carbon, and the formation of high-entropy carbide phase from high-entropy alloy and carbon.

Summary: Wet grinding was used to reduce the particle size of congruent lithium niobate to about 12-15 nm, leading to the release of lithium oxide. Formation of a lithium-deficient phase, LiNb3O8, was confirmed by X-ray diffractometry and Raman spectroscopy, with correlation found between the composition change and the total surface area of the nanopowder.

Summary: The mechanical degradation of Cu3B2O6 (CBO) through ball milling (BM) is found to efficiently decompose pollutants. The efficiency of CBO under BM is significantly higher than benchmark BaTiO3 and CBO under ultrasonication, attributed to the strong piezoelectric field and abundant reactive species generated. These findings provide insights into the development of high efficient piezocatalytic reactions based on piezocatalysts and ball milling combined strategy.

Summary: This study utilized high-energy ball milling and nanoscale iron oxide coating technology to produce an activated potassium feldspar with strong adsorption capacity for K-solubilizing bacteria. The results showed that ball milling reduced particle size and increased available K content, specific surface area, and total pore volume. Coating with nanoscale Fe-oxide further increased surface area and pore volume, and improved adsorption capacity for Bacillus subtilis cells. This carrier material has potential for efficient supply of K to soil as a bio-potassium fertilizer.

Summary: This study assessed the effect of small fractions of β-CPP on the in vitro osteoclastic resorption of β-TCP and found that β-CPP fractions significantly inhibited the resorption of β-TCP. The study also examined the impact of β-CPP and HA impurities on the physico-chemical properties of β-TCP powders and sintered cylinders.

Summary: Lanthanum strontium manganite with perovskite structure was successfully produced through mechanochemical synthesis. Annealing at higher temperatures leads to reduced lattice parameters and increased crystallite size. Room temperature superparamagnetic behavior was observed in annealed samples, along with a slight decrease in electrical resistance at room temperature.
