Zero X-Y Shrinkage Multi-Layered Ceramic Substrate with Copper Foil Patterning System.

Thin Foil Preparation of Metal Ceramic Matrices

Thin foil preparation for metal particles in brittle ceramic matrices is particularly difficult, due to differential thinning of the component materials. This paper considers the preparation of thin foils of stony meteorites. Stony meteorites have a composite nature consisting of small metal particles (<200 pm) embedded in an inherently brittle silicate matrix. Specimens of this type are diffic...

Ballistic Penetration of Multi-layered Ceramic/steel Targets

The response of multi-layered ceramic/steel targets to high velocity impact and penetration has been investigated through experiments and finite element simulations. Damage quantification and the material stresses and velocity histories provided by experiments are used as constraints to be satisfied by numerical simulations of the ballistic penetration event. Experimental and numerical observat...

Optimum Aggregate Inventory for Scheduling Multi-product Single Machine System with Zero Setup Time

In this paper we adopt the common cycle approach to economic lot scheduling problem and minimize the maximum aggregate inventory. We allow the occurrence of the idle times between any two consecutive products and consider limited capital for investment in inventory. We assume the setup times are negligible. To achieve the optimal investment in inventory we first find the idle times which minimi...

Temperature dependence of Raman spectra of graphene on copper foil substrate

We investigate the temperature dependence of the phonon frequencies of the G and 2Dmodes in the Raman spectra of monolayer graphene grown on copper foil by chemical vapor deposition. The Raman spectroscopy is carried out under a 532.16 nm laser excitation over the temperature range from 150 to 390 K. Both the G and 2D modes exhibit significant red shift as temperature increases, and the extract...
