In this work, we prove the existence of decay solution in mean square moment for a class of stochastic integro-differential equations with infinite delays driven by fractional Brownian motion. The existence of mild solutions is obtained by using the Banach fixed point theorem and some inequality technique.

In this paper, we introduce a new approximate projection algorithm for finding a common solution of multivalued variational inequality problems and fixed point problems in a real Hilbert space. The proposed algorithm combines the approximate projection method with the Halpern iteration technique. The strongly convergent theorem is established under mild conditions.

In the paper "Remarks on decaying solutions to distributed order differential equations", we present results on the asymptotic behavior of the solutions to distributed order differential equations in Euclidean spaces. The paper develops some recent results in [1] on fractional differential equations to the case of more general nonlocal derivatives. We utilize the detailed behavior of the relaxation functions instead of the Mittag–Leffler functions. The typical decaying rate is logarithmic due to the ultra-slow phenomenon.

The corrosion inhibition of mild steel alloys is of tremendous technological importance due to their increased industrial applications. Potentiodynamic polarization and electrochemical impedance spectroscopy techniques were used to establish the effect of different concentrations of HCl on the corrosion behavior of mild steel. A study was conducted on the inhibition of dissolution for a mild steel alloy in the most corrosive concentration of HCl (5 M) by adding different concentrations of aqueous extract of Hibiscus sabdariffa plant (named karkade or rosselle) as an ecofriendly inhibitor.

In this study, encapsulation processes of cetyltrimethylammonium bromide (CTAB) or sodium dodecyl sulfate (SDS) monomers into the cavity of β -cyclodextrin (β -CD) were applied to synthesize mono- and bis (indolyl)methylmalononitrile derivatives by a one-pot three-component reaction of an aldehyde, malononitrile, and indole in an aqueous solution. These two inclusion complexes proved to be superior to CTAB or SDS individually, as cationic or anionic surfactants, respectively, for accessing high yields of pure products within shorter reaction times.

In this paper, we present a result on Hyers-Ulam stability for a class of nonlocal differential equations in Hilbert spaces by using the theory of integral equations with completely positive kernels together with a new Gronwall inequality type. The paper develops some recent results on fractional differential equations to the ones involving general nonlocal derivatives. Instead of Mittag-Leffler functions, we must utilize the characterization of relaxation function.

The corrosion inhibition of mild steel in 0.5 M H2SO4 solution has been investigated using electrochemical methods, X-ray diffraction (XRD) and scanning electron microscope (SEM). The adsorption and inhibition action of acid corrosion of mild steel using cetyltrimethylammonium bromide (CTABr) and different halides (NaCl, NaBr and NaI) has shown synergetic effect. The results showed that the protection efficiency (P%) has high values at considerable high concentration of CTABr. However, in the presence of the different halides, the P increases dramatically at low concentration of CTABr.

We study the long time behavior of the bounded solutions of non homogeneous gradient-like system which admits a strict Lyapunov function. More precisely, we show that any bounded solution of the gradient-like system converges to an accumulation point as time goes to infinity under some mild hypotheses.

This paper intends to study some dynamical properties of a stochastic three-dimensional Lotka–Volterra system. Under some mild assumptions, we first introduce a simple method to show that the model has a global and positive solution almost surely. Secondly, we prove that this model has a stationary distribution. Then we study the global asymptotic stability of the positive solution. Finally, some numerical simulations are introduced to illustrate the theoretical results.

In this paper, we investigate the existence and uniqueness of a piecewise asymptotically almost periodic mild solution to nonautonomous neutral Volterra integro-differential equations with impulsive effects in Banach space. The working tools are based on the Krasnoselskii’s fixed point theorem and semigroup theory.

This paper is concerned with the existence of global mild solutions and positive mild solutions to initial value problem for a class of mixed type semilinear evolution equations with noncompact semigroup in Banach spaces. The main method is based on a new fixed point theorem with respect to convex-power condensing operator.

The corrosion inhibition of mild steel in 0.01M HCl acid solution by water extract of Green tea has been studied using electrochemical method. The results of the study reveal that the inhibition efficiency of the extract is found to vary with concentration and period of immersion. Thermodynamic consideration reveals that adsorption of Green tea extract on mild steel surface is spontaneous and occurs according to Langmuir adsorption isotherm. Physical adsorption mechanism has been proposed for the adsorption of the inhibitor from the values of some kinetic and thermodynamic parameters.

Trong bài viết này, các tác giả đã nghiên cứu khả năng ức chế ăn mòn cho thép thường trong dung dịch axit HCl của dịch chiết nước lá chè xanh bằng phương pháp điện hóa. Kết quả nghiên cứu cho thấy ở các nồng độ dịch chiết nước lá chè xanh khác nhau đều có khả năng ức chế ăn mòn thép thường. Hiệu quả ức chế ăn mòn nói chung tăng khi nồng độ dịch chiết tăng.
