The paper presents a case study on the use of in-situ reinforcement technique, namely soil nail, to stabilize a shallow foundation of an existing building constructed on weathered siltstone. The two-dimensional limit equilibrium method was employed to evaluate the stability of the existing foundation with/without incorporating soil nail elements.

This article deals with ballooncopters that have a special solution to assemble a multicopter with the balloon and payload as a scheme of two seriesly hung pendulums. The assembly scheme many times reduces the necessary power of the rotors when needed to tilt the thrust vector. This new assembly scheme requires balance and stability considerations when flying in windy conditions.

The geometries and relative stabilities of 15 tautomeric forms and the corresponding isomers of the studied molecules have been identified and their relative stabilities are investigated. The potential energy profiles and intrinsic reaction coordinates (IRC) calculations along the proton transfer coordinates both in the ground and in the excited state are monitored as well. The impact of the donating (OMe) and withdrawing (NO2) groups on the single and double proton transfers are investigated both in the gas phase and solution.

The present study focuses on the preparation of silver/copper bimetallic hybrid nanoparticles by green method from precursor solutions of silver nitrate & copper nitrate and the locally available citrus fruit (lemon) peel extract which behaves as the stabilizing and reducing agent. Initially, the formation of hybrid nanoparticles was noticed in the reaction mixture by colour change.

In this study, we present an innovation method to synthesize ZnO nanoparticles colloidal solution by Zn2+ precipitation, and using COS and COS-I2 as a stabilizer agent to replace high molecular weight chitosan in previous studies. [17,18,24] It was favorable due to COS with small Mw did not precipitate at alkaline pH. Thus, ZnO/COS and ZnO/COS-I2 composite nanomaterials were prepared in this work will be oriented to use as antimicrobial agrochemicals, and post-harvest preservation.

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

A major challenge for outdoor uses of methylammonium lead halide (MAPbX3) solar cells is the poor durability of the perovskite film under humidity. This instability is due to limitations of the dipping or spin coating process in producing MAPbX3 films through a direct reaction between PbI2 and methylammonium iodide (MAI) in an organic solvent. In this study, we devised an eco-friendly and cost-effective method to fabricate MAPbX3 films using an aqueous solution of Pb(NO3)2 and MAI vapour. I

In this study, we propose a novel approach for the synthesis of AISe core and highly luminescent AISe/ZnS core/shell NCs in a 2-step procedure. First, the AISe core NCs were produced using both glutathione and citric acid as dual stabilizers at 96 °C for 20 min at different pH values of the reaction solution.

For the resulting equation of double-curved shells, which is formed by revolution of an arbitrary in-plane meridian curve and cannot be represented analytically, there exists no analytical approach to problem setting and solution. This paper presents the digitalization of the meridian curve in the polar coordinate system, which forms double number series.

In this paper, we establish second-order sufficient optimality conditions for optimal control problem of 2D g-NavierStokes equations. The long-time behavior of the strong solutions was studied very recently in the autonomous case in terms of existence of a global attractor, and existence and stability of a unique stationary solution.

This paper investigates the stability of solutions for the class of semi-affine variational inequalities in real Hilbert spaces whose feasible set does not depend on parametric. As an application, we obtain the stability of solutions for the parametric quadratically constrained quadratic programming problems in real Hilbert spaces.
