20191212&ensp·&enspSolventfree reaction using a highspeed ball milling technique has been first applied to crossdehydrogenative coupling (CDC) reactions between tetrahydroisoquinolines and three types of pronucleophiles such as nitroalkanes, alkynes, and indoles. All coupling products were obtained in good yields at short reaction times (no more than 40 min). When alkynes and indoles were used asLeave MessageOnline Service
Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years. It has been used in size comminutions of ore, mineral dressing, preparing talc powders and manyLeave MessageOnline Service
202091&ensp·&enspMechanochemical technique aims to strike a balance between defect formation via ball milling and size adjustment of a solid grain to nanoscale (<1000 nm) (Ullah et al., 2014).During the process, a highenergy mill is employed and a specific powder charge is placed along with a milling medium (Lin et al., 2017).The kinetic energy generated during the motion of moving balls is applied to theLeave MessageOnline Service
2013314&ensp·&enspJar, Ball and Pebble Milling . Types of Mills . Ball and Pebble Mills: The expressions ball milling and pebble milling are frequently used interchangeably. Usually, however, a ball mill is referred to as one that uses steel balls as grinding media, while a pebble mill is one that uses flint pebbles or manufactured ceramic shapes.Leave MessageOnline Service
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 towardLeave MessageOnline Service
2020620&ensp·&enspThe overarching objective of this study is to evaluate ballmilled magnetic BC as an alternative and effective adsorbent for contaminant removal. Ballmill extrusion was used as a solventfree synthesis method to prepare magnetic adsorbent ball milling Fe 3 O 4 nanoparticles with BC or AC. Physicochemical properties of the resultant magneticLeave MessageOnline Service
