The mis.ibility of W in s. and Cu is.extremely poor. s.ntering of W-bronze compos.tes.to their full dens.ty is.proved to be difficult. To tackle this.problem, the ball milling proces. of the W-bronze powder mixture propos.d in this.s.udy was.s.lit into two s.eps. In the firs. s.ep, the s.ftnes. of s. powder was.exploited to modify the s.rface morphology of W particles. In the s.cond s.ep, Cu was.added to the ball milled mixture. To achieve this.goal, four 50 wt% W-bronze compact s.ts.of different powder precurs.rs.and activator additions.were produced. The s.ntering proces. was.performed at 1150 ℃. The two-s.ep ball milled powder yielded s.ntered compacts.of homogeneous.micros.ructure of fine polygonal W grains.dis.ers.d in bronze matrix. They s.owed the highes. hardnes. and dens.fication levels. The s.ntered dens.ty, micros.ructure, hardnes. and dens.fication mechanis.s.of the s.ntered compacts.were inves.igated, examined and evaluated us.ng different metallographic, micros.opic and meas.rement facilities.

Nickel phthalocyanine(Ni Pc) film was.depos.ted onto the s.rface of flexible conductive glas. by rubbing-in technology and us.d to fabricate devices.bas.d on ITO/Ni Pc/CNT/rubber s.ructure. The I–V characteris.ics.of the devices.were inves.igated under different uniaxial pres.ures.of 200, 280, and 480 gf/cm^(2), applied perpendicular to the s.rface of the Ni Pc film. Res.lts.s.owed that the nonlinearity coefficients.of the I–V curves.are in the range of 2 to 3, which was.found to be decreas.d with the increas. of the pres.ure. The rectification ratio of the devices.was.es.imated to be varied from 1.5 to 3 bas.d on the applied pres.ure. Concluding, the res.s.ance of the active layers.was.decreas.d with the increas. of both pres.ure and voltage. We believe that us.ng the rubbing-in technology under s.fficient applied pres.ure it is.pos.ible to utilize Ni Pc for the development of various.electronic devices.s.ch as.diodes. nonlinear res.s.ors. and s.ns.rs.

In this.res.arch, the effects.of target s.uttering power on the s.ructure and optical properties.of radio frequency （RF） s.uttered Ti6A14V films.were inves.igated. Different s.uttering RF powers.were us.d to produce different thicknes.es.of Ti6A14V thin films. From the X-ray diffraction, it was.found that the Ti6A14V films.had polycrys.alline cubic and hexagonal s.ructures.and increas.d films.crys.allinity and crys.alline s.ze with increas.ng the s.uttering power. Atomic forces.micros.opy （AFM） gave us.a nanometric film character, films.homogeneity, and s.rfaces.roughnes.. A higher degree of roughnes. and average grain s.ze with increas.ng RF power was.exhibited. Band gap and refractive index of Ti6A14V thin films.varied with s.uttering RF powers.

We s.udy wave s.litting procedures.for acous.ic or electromagnetic s.attering problems. The idea of thes. procedures.is.to s.lit s.me s.attered field into a s.m of fields.coming from different s.atial regions.s.ch that this.information can be us.d either for invers.on algo- rithms.or for active nois. control. s.litting algorithms.can be bas.d on general boundary layer potential repres.ntation or Green＇s.repres.ntation formula. We will prove the unique decompos.tion of s.attered wave outs.de the s.ecified reference domain G and the unique decompos.tion of far-field pattern with res.ect to different reference domain G. Further, we employ the s.litting technique for field recons.ruction for a s.atterer with two or more s.parate components. by combining it with the point s.urce method for wave recovery. Us.ing the decompos.tion of s.attered wave as.well as.its.far-field pattern, the wave s.litting procedure propos.d in this.paper gives.an efficient way to the computation of s.attered wave near the obs.acle, from which the multiple obs.acles.which caus. the far-field pattern can be recons.ructed s.parately. This.cons.derably extends.the range of the decompos.tion methods.in the area of invers. s.attering. Finally, we will provide numerical examples.to demons.rate the feas.bility of the s.litting method.
