Ball Milling - an overview | ScienceDirect Topics

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 many ...

Ball Mills - an overview | ScienceDirect Topics

Wet ball or attrition milling techniques can be used for the synthesis of homogeneous powder mixture. Al 2 O 3 /SiC composites are widely prepared by this conventional powder mixing route by using ball milling [70]. However, the disadvantage in the milling step is that it may induce certain pollution derived from the milling media. 6.3.1.1 Ball ...

A review on metal-organic frameworks: Synthesis and ...

Sep 01, 2019· Using a suitable and green one-pot solvent free mechanochemical ball-milling of the MOF components and sodium alginate powder, the alginatecoated ZIF-8 nanoparticles ([email protected] NPs) were produced. These researchers trapped metformin (an oral anti hyperglycemic agent to cure type II diabetes) inside the alginate-coated ZIF-8 pores.

Drug Solubility: Importance and Enhancement Techniques

Jul 05, 2012· Solubility, the phenomenon of dissolution of solute in solvent to give a homogenous system, is one of the important parameters to achieve desired concentration of drug in systemic circulation for desired (anticipated) pharmacological response. Low aqueous solubility is the major problem encountered with formulation development of new chemical entities as well as for the generic …

Recent Advances in Single-Atom Electrocatalysts for Oxygen ...

Aug 14, 2020· This ball-milling method could be easily scaled up to synthesize gram-level SAECs in one pot depending on the size of furnace and ball-milling machine. Furthermore, this method was extended to prepare ZnO- and CuO-supported Pd-based single-atom catalysts on a kilogram scale [ …

Single Atomic Iron Catalysts for Oxygen Reduction in ...

Sep 13, 2017· It remains a grand challenge to replace platinum group metal (PGM) catalysts with earth-abundant materials for the oxygen reduction reaction (ORR) in acidic media, which is crucial for large-scale deployment of proton exchange membrane fuel cells (PEMFCs). Here, we report a high-performance atomic Fe catalyst derived from chemically Fe-doped zeolitic imidazolate frameworks …

Overview of milling techniques for improving the ...

Jul 01, 2015· Ball milling of pure drug mixtures have also been investigated. More recently, ball milling of a combination of two BCS Class II drugs, simvastatin and glipizide, resulted in the formation of stable co-amorphous mixtures . Despite the efficiency of ball milling for size reduction or amorphization, it is less amendable to scale up.
