This review critically evaluates the synthesis, characterization, and application of ball-milled biochar nanomaterials based on the latest findings. Limitations such as feedstock selection, process optimization, product homogeneity and reusability, environmental risks, and sustainability assessment remain challenging for further studies.


A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. ...

Volume of aluminum= mass/density=3.70×10-5 m3 Volume of Aluminum Oxide=7.59×10-7 m3. The mass of the balls used in the ball milling jar is generally 10 to 15 times the mass of powders are used [9]. Therefore by considering 10 times the mass of …


High-energy ball milling is a convenient way to produce nanosized powders. It is the most common method reported in the literature for the synthesis of intermetallic nanoparticles. Before a mechanical milling is started, powder (s) is loaded together with several heavy balls (steel or …


In this review, the possibility of utilizing the method of ball milling to further broaden the application potential of this material is discussed. The particular application fields include the formation of nanophases, bioceramics synthesis, formation of composites and …


Mineral carbonation is considered to be the most stable mechanism for the sequestration of CO2. This study comprises a comparative review of the effect of ball milling on the CO2 uptake of ultramafic/mafic lithologies, which are the most promising rocks for the mineralization of CO2. Samples of dunite, pyroxenite, olivine basalt and of a dolerite quarry waste material were previously subjected ...


Ball milling (BM) is a well-established technique for producing different materials in powder shape. Dynamical analysis of BM helps to optimize the process through simple but general relations (e.g., definition of an equivalent milling time). Concerning the field of study of magnetocaloric effect (MCE), BM is used in different ways: as a single step process (mechanical alloying), as an initial ...

However, the utilization of ball milling in asymmetric organic synthesis has not been adequately investigated. Thus, the aim of this review is to highlight the attractive features of the applications of mechanochemistry via ball milling in asymmetric organic syntheses in order to attract the attention of a wider section of the synthesis community.


In this review, we present the very recent progress, from 2016 to 2021, on catalyzing the hydrogen sorption of Mg-based materials by ball milling. The various catalyzing routes enhancing the hydrogenation performance, including in situ formation of catalysts and synergistic improvement achieved by using multiple additives, will also be summarized.

Palladium, rhodium, ruthenium and palladium–copper SACs were all produced using the ball-milling process. 'We estimate that with our strategy, the preparation cost of noble metal SACs is less than $0.10 (£0.08) per gram,' says Ma. He adds that this shows 'great promise for commercial applications' once the process is optimised further.
