Effect of High Energy Ball Milling Washing Process on

Nd2Fe14B particles were obtained from mixture of neodymium oxide, iron oxide, boric acid and CaH2 by reduction-diffusion process. Two different washing processes were used for the separation of magnetic particles from Ca and CaO matrix: usual washing with water and planetary ball milling process in ethanol media. Nd2Fe14BHx hydrogenated state was formed after usual washing with water.

Nanoscale Mg–B via Surfactant Ball Milling of MgB2

2020-10-1  We demonstrate improved hydrogen storage properties of a nanoscale Mg–B material made by surfactant ball milling MgB 2 in a mixture of heptane, oleic acid, and oleylamine. Transmission electron microscopy data show that Mg–B nanoplatelets are produced with sizes ranging from 5 to 50 nm, which agglomerate upon ethanol washing to produce an

High Energy Ball Milling Processes Gold Nanoparticles

2021-3-12  Ball milling has been utilized in various industries to perform size reduction for a long time. Recently, materials with novel microstructures and properties have been synthesized successfully via high-energy ball milling processes.[53,54] Although different terms have been used to describe the high-energy ball milling processes, three terms are generally used to distinguish powder particle

2021-2-1  cellulose oleic acid via ball milling, and the state of different COEs was controlled by the reaction conditions. As seen in Fig. S4, the obtained S300-T4, S300-T6, and S400-T2 were grey powder because the rotational speed was too low or the reaction time was too short to meet the satisfactory mechanochemical esterification. When the

Solvent-free one-pot synthesis of 1,2,3-triazole

A one-pot procedure for the synthesis of 1,2,3-triazole derivatives by a three-component coupling of alkyl (benzyl) halides or aryl boronic acids, sodium azide and terminal alkynes over copper(II) sulfate supported on alumina (Cu/Al 2 O 3) under ball-milling in the absence of any solvent and additive has been developed. The product was isolated by simple washing of the crude reaction residue

Eco-Friendly Facile Three-Step Recycling Method of

2020-6-8  In order to remove CaO particles completely, ball milling was done in ethanol which removed CaO particles seven times more efficiently as compared to the washing with water. Efficient removal of CaO and crystallite modification after ball milling increased the (BH) max value of the recycled (Nd-RE)2Fe14B powder up to higher than 10 MGOe.

Redox reactions of small organic molecules using ball

Mixing solid reactants in a ball mill is a promising means of avoiding the copious solvent waste associated with most chemical syntheses. Kubota et al. now report that adding a piezoelectric catalyst to the mix can promote bond formation through apparent electron transfer cycles (see the Perspective by Xia and Wang). Specifically, barium titanate activates aryl diazonium salts toward
