A member of McGill Universitys chemistry department, Friscics interest was piqued during post-doctoral work with William Jones at the Pfizer Institute for Pharmaceutical Materials in the United Kingdom. This was where he learned that grinding molecules together can promote hydrogen bond associations without the need for a solvent or catalyst.
The development of gas sensing devices with high sensitivity, good selectivity and excellent stability is becoming increasingly important since toxic or harmful gases are a threat to human health. Herein, we report a simple grinding-calcination method to prepare high

2019-5-25High-purity CuS nanosheets have been successfully synthesized at room temperature via a quick, simple, and efficient grinding approach by using CuCl22H2O, thiourea, and NaOH as starting materials. The X-ray diffraction XRD patterns and Raman spectra indicated that as-prepared CuS was of high purity and scanning electron microscope SEM images showed the sheet-like nanostructure.

2018-6-4This simple grinding method afforded a nanosized, multifunctional biomaterial that was used for cell imaging and drug delivery, and it can be extended to other MOFs to widen their applications. Keywords Metal-organic framework , nanoparticles , bioimaging , drug delivery , endocytosis
chemistry has been developed rapidly as an efficient and selective method, since molecules in the crystals has been arranged tightly and regularly. 33 One of the methods belonging to this protocol is a simple grinding method called grindstone mechanochemical method which reactants are ground simply by mortar and pestle.
Simple grinding method in chemistry Glass Chemistry Encyclopedia structure reaction water Glass is a state of matter. It is a solid produced by cooling molten material so that the internal arrangement of atoms or molecules remains in a random or disordered state similar to the arrangement in a liquid.
2010-8-1The grinding method has increasingly been used in organic synthesis. Recently Ball-milling grinding technique has been widely used in synthetic organic chemistry .Compared with traditional methods, many organic reactions occur more efficiently in the solid-state than in solution and in many cases even more selectively, because molecules in the crystals are arranged tightly and regularly .
grinding method is the absence of toxic solvent. The plausible mechanism for the efficient synthesis of heterocyclic fullerene derivatives under grinding conditio ns

2004-11-1Grindstone Chemistrya greatly evolved version of Todas method of grinding solids together for solvent-free chemical reactionshas been described and its usefulness illustrated by the successful application of this technique to a simplified process for conducting the multi-component Biginelli reaction for the synthesis of physiologically active tetrahydropyrimidinones.
2020-7-10Method i- Solvent free Grindstone method- A mixture of 3-acetyl-2-aryl-1H-indoles 3mmol and MgHSO 42 0.04gm was grinded together in a mortar using a pestle to generate yellow colored enolate. Then aryl aldehydes 3mmol was added to it and grinding continued further to give orange red colored tacky solid within 10-20 minutes.

2018-10-16Grinding, on the other hand, offers the advantages to be a simple, fast and highly effective method for the preparation of drugCD inclusion complexes in the solid state, generally not requiring the use of organic solvents 39.
Fabrication of capillaries with tapered tips is an important technique that is required in many analytical chemistry areas, such as ESI-MS, CE, electrochemical analysis, and microinjection. This paper describes a simple and effective grinding-based fabrication method for capillaries with tapered tip
A method for the preparation of ore solutions by grinding the ore with distilled water is developed for the analysis of minerals and ores in the field by the circular thin-layer Chromatographic technique.
In its various forms grinding can be used on wet, dry, and frozen samples, however it is most efficient on solid samples. One key characteristic of grinding is that friction generates heat and at times can be significant. Consequently, the heat tolerance of the analyte should be considered when selecting a grinding method.
