Mechanoredox is a conceptually new redox system, in which electrons are transferred from distorted piezoelectric materials to trigger organic transformations. In their Research Article on page 22570, K. , H. Ito et al. describe how the piezoelectric reduction of Umemoto reagents produces a CF 3 radical, as represented by the cover picture. . Based on this finding, a method for the solid ...

LiTaO3: Tm3+, Yb3+ powders were synthesized by a high-energy ball-milling (HEB) method compared with the conventional solid-state reaction (SSR) method. Under the excitation of 980 nm laser, the strong blue emission (477 nm) band is observed and …
Commercial powders of pure magnesium were processed by high-energy ball milling. The microstructural and morphological evolution of the powders was studied using scanning electron microscopy (SEM), energy dispersive spectrometry (EDX) and X-ray diffraction (XRD). From the results obtained, it was determined that the ball size is the most influential milling parameter.
RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming ...
Particle size plays an important role in the electrochemical performance of cathodes for lithium-ion (Li-ion) batteries. High energy planetary ball milling of LiNi 1/3 Mn 1/3 Co 1/3 O 2 (NMC) cathode materials was investigated as a route to reduce the particle size and improve the electrochemical performance. The effect of ball milling times, milling speeds, and composition on the structure ...
Herein, we report a straightforward, eco-friendly, and scalable ball milling method for the synthesis of Co-alloyed Pt (Pt 1 /Co) single-atom alloy (SAA) catalysts at kilogram levels. The catalysts exhibit superior catalytic performance for the hydrodeoxygenation of HMF to DMF, obtaining HMF conversion and 92.9% selectivity to DMF under 1.0 MPa H 2 at 180 °C for 2 h.
A one-step method which involves exfoliating graphite materials (GIMs) off into graphene materials (GEMs) in aqueous suspension of CL-20 and forming CL-20/graphene materials (CL-20/GEMs) composites by using ball milling is presented. The conversion of mixtures to composite form was monitored by scanning electron microscopy (SEM) and powder X-ray diffraction (XRD).

The ball mill machine (NanDa Instrument Plant, Nanjing, China) was operated at 500 rpm with rotation direction changed every 0.5 h. The ball milling time and weight ratio of biochar to milling ball, two important milling parameters, were further investigated to address the effects of ball milling on biochar sorption for NSAIDs.

The magnetic properties of metastable Co 3 C synthesized via reactive ball milling in nitrogen and argon are reported.. Dissolved nitrogen is effective in increasing transformation rate, coercivity, and decomposition temperature of Co 3 C.. A maximum coercivity value of 106 kA/m (1.34 kOe) is obtained in a 473 K annealed Co 3 C sample.
