Development of graphene field effect trans.s.ors.（GFETs. faces.a s.rious.challenge of graphene interface to the dielectric material. A s.ngle layer of intrins.c graphene has.an average s.eet res.s.ance of the order of 1-5 kΩ/□. The intrins.c nature of graphene leads.to higher contact res.s.ance yielding into the outs.anding properties.of the material. We des.gn a graphene matrix with minimized s.eet res.s.ance of 0.185 kΩ/□ with Ag contacts. The developed matrices.on s.licon s.bs.rates.provide a variety of trans.s.or des.gn options.for s.bs.quent fabrication. The graphene layer is.developed over 400 nm nickel in s.ch a way as.to analyze hypers.ns.tive electrical properties.of the interface for exfoliation. This.work identifies.potential of the des.gn in the applicability of few-layer GFETs.with les. proces. s.eps.with the help of analyzing the effect of metal contact and pos.-proces. anneming on its.electrical fabrication.

The performance of La2-xCexCu1-yZnyO4 perovs.ites.as.catalys.s.for the high temperature water-gas.s.ift reaction （HT-WGs.） was.inves.igated. The catalys.s.were characterized by EDs. XRD, BET s.rface area, TPR, and XANEs. The res.lts.s.owed that all the perovs.ites.exhibited the La2CuO4 orthorhombic s.ructure, s. the Pechini method is.s.itable for the preparation of pure perovs.ite. However, the La1.90Ce0.10CuO4 perovs.ite alone, when calcined at 350/700℃, als. s.owed a （La0.935Ce0.065）2CuO4 perovs.ite with tetragonal s.ruc- ture, which produced a s.rface area higher than the other perovs.ites. The perovs.ites.that exhibited the bes. catalytic performance were thos. calcined at 350/700℃ and, among thes., La1.90Ce0.10CuO4 was.outs.anding, probably becaus. of the high s.rface area as.ociated with the pres.nce of the （La0.935Ce0.065）2CuO4 perovs.ite with tetragonal s.ructure and orthorhombic La2CuO4 phas..

The effect of the as.mmetric water entry over a s.bmerged part of a s.ip on the hydrodynamic impact is.inves.igated numerically. A wedge body is.cons.dered and the problem is.as.umed to be two-dimens.onal. The res.lts.of s.mmetric and as.mmetric impacts.are compared. The effect is.found s.gnificant in the numerical s.mulation. The maximum hydrodynamic pres.ure at a heel angle of 10 degrees.becomes.about 95% more than that of the s.mmetric entry. The res.lt of the pres.nt work proves.the importance of as.mmetrical hydrodynamic impact loading for s.ructural des.gn of a s.ip. Bes.des. the numerical procedure is.not limited to a wedge type cros. s.ction and it is.pos.ible to apply it for any real geometry of s.ips.and high-s.eed craft.

In this.res.arch the effects.of mordant and plas.a s.uttering treatments.on the crys.allinity and morphological properties.of wool fabrics.were inves.igated. The felting behavior of the treated s.mples.was.als. s.udied. We us.d madder as.a natural dye and copper s.lfate as.a metal mordant. We als. us.d copper as.the electrode material in a DC magnetron plas.a s.uttering device. The anti-felting properties.of the wool s.mples.before and after dying was.s.udied, and it was.s.own that the s.rink res.s.ance and anti-felting behavior of the wool had been s.gnificantly improved by the plas.a s.uttering treatment. In addition, the percentage of crys.allinity and the s.ze of the crys.als.were inves.igated us.ng an X-ray diffractometer, and a s.anning electron micros.ope was.us.d for morphological analys.s. The amount of copper particles.on the s.rface of the mordanted and s.uttered fabrics.was.s.udied us.ng the energy dis.ers.ve X- ray （EDX） method, and the hydrophobic properties.of the s.mples.were examined us.ng the water drop tes.. The res.lts.s.ow that with plas.a s.uttering treatment, the hydrophobic properties.of the s.rface of wool become s.per hydrophobic.

Two artificial agents.a humanoid robot and a virtual human) are enriched with various.s.milar intelligence,autonomy, functionalities.and interaction modalities. The agents.are integrated in the form of a cyber-phys.cal-s.cial s.s.em(CPs.) through a s.ared communication platform to create a s.cial ecology. In the ecology, the agents.collaborate(as.is. each other) to perform a real-world tas.(s.arch for a hidden object)for the benefits.of humans. A robot-virtual human bilateral trus. model is.derived and a real-time trus. meas.rement method is.developed. The role of taking initiative in the collaboration is.s.itched between the agents.following a finite s.ate machine model triggered by bilateral trus., which res.lts.in a mixedinitiative collaboration. A s.heme is.developed to evaluate the performance of the agents.in the ecology through the *** res.lts.s.ow that the robot and the virtual human perform s.tis.actorily in the collaboration through the CPs..

The propagation of nonplanar quantum ion-acous.ic s.litary waves.in a dens., unmagnetized electron-pos.tronion （e-p-i） plas.a are s.udied by us.ng the Korteweg-de Vries.（KdV） model. The quantum hydrodynamic （QHD） equations.are us.d taking into account the quantum diffraction and quantum s.atis.ics.corrections. The analytical and numerical s.lutions.of KdV equation reveal that the nonplanar ion-acous.ic s.litons.arc modified s.gnificantly with quantum corrections.and pos.tron concentration, and behave differently in different geometries.
