In this work, Ti 25 Cu 75 meltspun partially amorphous alloy was used as a source of Ti and Cu to synthesize insitu TiCCu nanocomposites. The reaction between the alloy and carbon started during ball milling and continued during Spark Plasma Sintering. At the same time, during ball milling, the alloy experienced phase transformations: crystallization of the amorphous phase was followed by

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavyduty gang milling operations.

According to general theory that SiO exists in the interface of Si and SiO 2 [8,,, ], SiO is prepared by local selfreduction of SiO 2 using a mixture of Si and SiO 2 at 1200 °C for more than 1 h followed by high energy ball milling [11,13]. However, these methods are lowyielding and powerwasting, which is not suitable for the largescale production. Relatively speaking, magnesiothermic

To prepare the nanoparticles, 100 g of 5 mm, 7 mm and 8 mm stainless steel balls were loaded into the ball mill jar as the grinding medium. Then, different amount of Iron(III) nitrate nonydrate and 3 g of hydrophilic vapor phase nanosilica were added, and a certain amount of ethanol solution was

· For example, ball milling under ambient conditions has been shown to induce a 15% w/w conversion of the αanomer to the βanomer due to the presence of moisture in the air (15). The stability of lactose must be investigated to ensure that lactosecontaining products are being stored appropriately such that the same anomeric content is maintained throughout the shelflife of the formulation.

Initial pasteurization conditions, known as flash pasteurization, were to heat the milk to 155 to 178°F ( to 81°C) for an instant followed by cooling. Pasteurization conditions were adjusted to 143°F (°C) for 30 minutes or 160°F (°C) for 15 seconds to inactivate Mycobacterium bovis, the organism responsible for tuberculosis.

Lithium aluminium hydride, commonly abbreviated to L, is an inorganic compound with the chemical formula Li Al H was discovered by Finholt, Bond and Schlesinger in 1947. This compound is used as a reducing agent in organic synthesis, especially for the reduction of esters, carboxylic acids, and solid is dangerously reactive toward water, releasing gaseous hydrogen (H 2).

Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between and mm depending on their subsequent use.

· During the sliding mode period, the deuterium oxide is progressively chemisorbed leading to the decrease of free deuterium oxide in the vial. This confirms that dangling bonds created by the mechanical stress react with D 2 O even if the ball mill is running in a sliding mode. The degradation of the graphite particles is very limited as indicated by the slight change of the graphite surface

In this study, hydoxyapatite (HA) prepared from calcined bovine bone was studied. Two methods were used for HA sintering: conventional sintering (CS) and microwave sintering (MS). HA was obtained by calcination of bovine bone at 800 °C for 4 h followed by wet ball milling. Afterwards, the powder was compacted under 75 MPa and sintered for 2 h at different temperatures, from 1050 to 1200 °C.

For instance, Sato Turtelli et al. investigated the quantity of Co 2+ cations in octedral sites for CoFe 2 O 4 prepared by solgel (SG) and ball milling (BM) methods. Their results showed that the quantity of Co 2+ in the octedral sites of the SG sample was less than that in the BM sample, causing the smaller saturation magnetization in the BM sample, as compared with the SG sample.

· Each material has a different response to the heat, which is characterized by its thermal expansion coefficient. The thermal expansion coefficient represents the amount that the material expands per each degree increase. Use a thermometer to measure the change in temperature in degrees Frenheit.
