INVESTIGATION OF THE CAUSE-EFFECT RELATIONSHIPS BETWEEN THE EXOTHERMIC REACTION AND THE MICROSTRUCTURES OF REACTIVE NI-AL PARTICLES PRODUCED BY HIGH ENERGY PLANETARY BALL MILLING

Investigation of the Cause-Effect Relationships between the Exothermic Reaction and the Microstructures of Reactive Ni-Al Particles Produced by High Energy Planetary Ball Milling

Reactive particles consisting of 2 Piece Sectional with Chaise nickel and aluminum represent an adaptable heat source for joining applications, since each individual particle is capable of undergoing a self-sustaining exothermic reaction.Of particular interest are particles with intrinsic lamellar microstructures, as they provide large contact area

Sub-THz Characterisation of Monolayer Graphene

We explore the optical and electrical characteristics of monolayer graphene by using pulsed optoelectronic terahertz time-domain spectroscopy in the frequency range of 325–500 GHz based on fast direct Classic Cap measurements of phase and amplitude.We also show that these parameters can, however, be measured with higher resolution using a free
