in this work, uranine-dyed zinc（tris） thiourea sulfate（ZTs） monocrystals, 26 mm×15 mm×10 mm in size, were synthesized by the solution method at ambient temperature. Their purity, crystallinity, lattice parameters, and functional modes were studied by x-ray diffraction, Fourier transform-infrared spectroscopy（FT-iR）, and FT-Raman spectroscopy analyses. The sodium ion content of the crystals from the dye was confirmed by elemental analysis. The diffused reflectance spectral analysis of the dyed crystal revealed a characteristic absorption band at 490 nm attributed to the presence of the dye. The calculated band gaps of the non-dyed and dyed crystals were 4.53 and 4.57 e V, respectively. A green emission peak at ～（512 ± 4） nm was observed in the photoluminescence spectrum of the uranine-dyed crystals. A differential scanning calorimetry study confirmed that the thermal stability improved owing to the addition of the dye. Dielectric and microhardness studies were conducted to examine the significant improvements in the corresponding properties of dyed crystals. The results demonstrated the competency of the dyed ZTs crystals for applications in optoelectronic devices.

For the first time, sodium metasilicate （sMs） doped ammonium dihydrogen phosphate （ADP） crystal was grown by slow evaporation solution technique. The unit cell parameters of grown crystal were deter- mined by means of single crystal X-ray diffraction technique. The qualitative analysis of sMs doped ADP crystal was carried out using energy dispersive X-ray and Fourier transform infrared analysis. The in- crease in optical transparency of doped ADP crystal was ascertained in the range of 200-900 nm using the UV-visible spectral analysis. The vital optical constants were evaluated using the transmittance data to explore various optical device applications of crystal. The assertive influence of sMs on mechanical and dielectric behavior of ADP crystal was investigated by means of Vickers microhardness analysis and dielectric studies, respectively. The enhancement in second harmonic generation （sHG） efficiency of sMs doped ADP crystal with reference to potassium dihydrogen phosphate （KDP） and ADP was confirmed from Kurtz-Perry sHG test. The Kerr lensing nonlinearity in sMs doped ADP crystal was identified by means of Z-scan analysis and the third order nonlinear optical susceptibility （χ3） was found to be 6.19 × 10-5 esu, which vitalizes its application for laser stabilization systems.

suitable stabilization conditions obtained for continuous chaotic systems are generalized to discrete-time chaotic systems. The proposed approach, leading to these conditions for complete synchronization is based on the use of state feedback and aggregation techniques for stability studies associated with the arrow form matrix for system description. The results are successfully applied for two identical discrete-time hyper chaotic Henon maps with different orders and also for non-identical discrete-time chaotic systems with same order namely the Lozi and the Ushio maps.

This paper addresses the stability problem for a class of switched nonlinear time varying delay systems modeled by delay differential equations. By transforming the system representation under the arrow form and using a new constructed Lyapunov function,the aggregation techniques,the Borne-Gentina practical stability criterion associated with the properties, new delay-independent stability conditions of the considered systems are established. Compared with the existing results in this area, the obtained result is explicit, simple to use and allows us to avoid the problem of searching a common Lyapunov function. Finally, an example is provided, with numerical simulations,to demonstrate the effectiveness of the proposed method.

Hybrid proton conducting membranes of poly（vinyl alcohol）（PVA） and phosphomolybdic acid （PMA） were prepared by solution casting method. The effect of PMA doping and PVA crosslinking density on the membrane properties and proton conductivity were investigated. The crosslinking reaction between the hydroxyl group of PVA and the aldehyde group of glutaraldehyde （GA） was characterized by iR spectroscopy. Proton conductivity of the membranes increases with an increase in concentration of the doped PMA and also with an increase in crosslinking density of the membranes. Proton conductivity results indicate that a significant amount of PMA was maintained in the membranes even after several hours of immersion in water. A maximum conductivity of 0.0101 s cm^-1 was obtained for the membrane with 33.3 wt% PMA and crosslinking density of 5.825 mol%. X-ray diffraction studies were carried out to investigate the influence of PMA doping and crosslinking density on the nature of the membranes. These properties make them very good candidates for polymer electrolyte membranes for direct methanol fuel cell application.

Let s be an inverse AG-groupoid （Abel-Grassmann groupoid） and define a relation γ on s by aγb if and only if there exist some positive integers n and m such that bm∈ （sa）s and an∈ （sb）s. We prove that s/γ is a maximal semilattice homomorphic image of s. Thus, every inverse AG-groupoid s is uniquely expressible as a semilattice Y of some Archimedean inverse AG-groupoids sα （α∈ Y）. Our result can be regarded as an analogy of the well known Clifford theorem in semigroups for AG-groupoids.
