The milling of silicon in a mixture of various 6-chloro-1-hexyne concentrations in hexene for 4 h resulted in silicon nanoparticles with different degrees of chloroalkyl group coverage as determined by 1 H NMR . This increasing coverage is indicated by the increasing chloroalkyl peak at around 3.55 ppm and a decreasing methyl peak at around 0.90 ppm, which is due to the
chloroalkyl-terminated silicon nanoparticles are produced by mechanochemical synthesis using high-energy ball milling in 6-chloro-1-hexyne facilitating a simultaneous formation and functionalisation of silicon nanoparticles with primary chloroalkyl groups. The pro-duced v-chloroalkyl-terminated silicon nanoparticles can be used for a number of organic

The bulk chemical composition of the Earth is mostly Iron (Fe, 34.6%), Oxygen (O 2, 29.5%), Silicon (Si, 15.2%), and Magnesium (Mg, 12.7%), with other elements making up the other 8%. These elements are distributed unevenly due to the layering, with Fe being concentrated in the core, Si, O 2 , and Mg being concentrated in the mantle, and Si, O ...

Apr 01, 2011 A facile and efficient, one step method using high-energy ball milling (HEBM) to produce chloroalkyl-functionalized silicon nanoparticles is described. HEBM causes silicon wafers to fracture and exposes reactive silicon surfaces. Nanometer-sized, functionalized particles with alkyl-linked chloro groups are synthesized by milling the silicon precursor in
The milling was performed for 12 h in a SPEX 8000D high-energy ball mill in a cold room at 2 C with an oscillation frequency of 18 Hz (SPEX CertiPrep Ltd., Metuchen, NJ). After the milling was completed, the vial contents were transferred to a plastic centrifugation tube and centrifuged for 30 min at 511 G.

A novel top-down procedure for synthesis of stable passivated nanoparticles uses a one-step mechanochemical process to form and passivate the nanoparticles. High-energy ball milling (HEBM) can advantageously be used to mechanically reduce the size of material to nanoparticles. When the reduction of size occurs in a reactive medium, the passivation of the nanoparticles
Mar 09, 2021 In 1952, Katherine Choy was hired to head the ceramics department at Newcomb College at Tulane University. Soon after her arrival, the promising young artist was the subject of Ceramics by Katherine Choy at the Delgado Museum of Art (todays NOMA) in May 1953. The exhibition checklist included 70 glazed vessels made in 1951, 1952 and 1953.
