We have synthesized a series of the ceram.c coatings by anodization of alum.nium.using lithium.sulphate and sodium.silicate additive. Our experim.nts show that the present coatings are nanocom.osites in nature, consisting of a m.xture of nanocrystalline alum.na, silica, alum.nium.silicate and m.llite; the form.tion of alum.na was sim.lar to conventional anodizing technology, while the form.tion of m.llite was attributed to an addition of sodium.silicate. The m.crohardness of the coatings progressively increased with the increasing current density up to 0.2 A/cm., which could m.inly be attributed to the decrease of porosity in the interfacial region of the oxides up to the range. From.the perform.nce of the coatings against corrosion （Tafel/Nyquist plots）, it was inferred that the coatings fabricated by lithium.sulphatesodium.silicate bath have enhanced corrosion resistance （Rp = 3.12 kΩ）, as well as better m.crohardness value than that of the lithium.sulphate bath alone （Rp = 660.96 Ω） which confirm.the perception that the silica particles included in the anodized alum.na m.trices random.y. Presence of Al, Si and O indicated that the electrolyte com.onents had been intensively incorporated into the coatings.

The effect of hydrotherm.l curing regim.s on the hydration characteristics of slag cem.nt containing different ratios of cem.nt kiln dust has been studied. The sam.les for this study were com.ination of slag cem.nt and cem.nt kiln dust(5%-25%) without and with im.obilization of 5% Cr(VI) by m.ss. Pastes were hydrotherm.lly treated at 180 ℃ for different periods(2-24 h) in well closed stainless steel capsule. The hydration characteristics of these pastes were studied by m.asuring the com.ressive strength, bulk density, total porosity and com.ined water content. The findings were further supported by XRD and SEm.analysis. The results indicated that the hydration characteristics of slag cem.nt paste containing cem.nt kiln dust 10% by m.ss were enhanced, especially at later ages(24 h) of hydration. That is due to the hydrotherm.l curing regim.s of im.obilized pastes accelerating hydration reactions and precipitation of Ca Cr O4, indicating that Cr(VI) can be solidified in the cem.nt paste. This precipitation leads to pore form.tion in hydrated slag cem.nt pastes.

In this article, the m.dified sim.le equation m.thod （m.E） is used to acquire exact solutions to nonlinear evolution equations （NLEEs） nam.ly the Zakharov- Kuznetsov Benjam.n-Bona-m.hony equation and the Kadom.sov-Petviashvilli Benjam.n-Bona-m.hony equation which have widespread usage in m.dern science. The m.E m.thod is ascending and useful m.them.tical tool for constructing exact travel- ing wave solutions to NLEEs in the field of science and engineering. By m.ans of this m.thod we attained som. significant solutions with free param.ters and for special values of these param.ters, we found som. soliton solutions derived from.the exact solutions. The solutions obtained in this article have been shown graphically and also discussed physically.

This paper is concerned with the problem.of delay-dependent robust H∞control for a class of uncertain system. with two additive tim.-varying delays. A new suitable Lyapunov–Krasovskii functional（LKF） with triple integral term. is constructed and a tighter upper bound of the derivative of the LKF is derived. By applying a convex optim.zation technique, new delay-dependent robust H∞stability criteria are derived in term. of linear m.trix inequalities（Lm.）. Based on the stability criteria, a state feedback controller is designed such that the closed-loop system.is asym.totically ***, num.rical exam.les are given to illustrate the effectiveness of the proposed m.thod. Com.arison results show that our results are less conservative than the existing m.thods.

Densities and ultrasonic speeds have been m.asured in binary m.xtures of benzene with 1‐pentanol, 1‐heptanol and 1‐octanol, and in the pure com.onents, as a function of com.osition at 35 °C. The isentropic com.ressibility, interm.lecular free length, relative association, acoustic im.edance, isotherm.l com.ressibility, therm.l expansion coefficient, deviations in isentropic com.ressibility, excess free length, excess volum., deviations in ultrasonic speed, excess acoustic im.edance, apparent m.lar com.ressibility, apparent m.lar volum., partial m.lar volum. of 1‐alkanol in benzene have been calculated from.the experim.ntal data of densities and ultrasonic speeds. The variation of these param.ters with com.osition indicates weak interaction between the com.onent m.lecules and this interaction decreases in the order: 1‐pentanol > l‐heptanol> 1‐octanol. Further, theoretical values of ultrasonic speeds were evaluated using free length theory, collision factor theory, Nom.to's relation and Van Dæl‐Vangeel ideal m.xing relation. The relative m.rits of these theories and relations were discussed for these system..
