PI/PM‐69 and PI/SP‐97 compositions were obtained by high‐energy ball mill. Bulk samples were obtained by compression moulding at 400 °C. The mechanical properties of the moulded PI and the reinforcing action of the PM‐69 and SP‐97 are strongly dependent on the mean size of …

High-velocity impact breakage for lower energy consumption ...

The feed material, top size 120 mm diameter, passes continuously, vertically (gravitationally) from a feeding funnel at the top through the comminution cylinder, typically taking 20 to 30 seconds. Each particle of the feed material is hit by multiple impacts at a high frequency and at very high velocities during this quick pass through the machine.

Theoretical Prediction of Negative Energy Specific to the ...

If an electron emits all of its rest mass energy mec2, the relativistic energy of the electron will become zero. According to the special theory of relativity, an electron whose relativistic energy is zero does not have photon energy. In this paper, however, an electron is regarded as having photon energy mec2 and negative energy −mec2, even when its relativistic energy is zero.

High-energy ball milling technique for ZnO nanoparticles ...

Apr 29, 2011· Obtaining nanoparticles of ZnO in this size (30 nm) is a remarkable result, maybe due to the use of the high-energy ball milling technique. Other investigators have reported 41, 43 that when the particles become small enough (typically hundreds of nm), further refinement cannot be observed due to equilibration of cold welding and fracturing.

Maximally supersymmetric field theories in various dimensions are believed to possess special properties due to extended supersymmetry. In four dimensions, they are free from UV divergences but are IR divergent on shell; in higher dimensions, on the contrary, they are IR finite but UV divergent. In what follows, we consider the four-point on-shell scattering amplitudes in D = 6, 8, 10 ...
