Abstract:
The interface between nanofillers and matrix plays a key role in determining the properties of nanocomposites, but the interfacial characteristics of nanocomposites such as molecular structure and interaction strength are not fully understood yet. In this work, the interfacial features of a typical nanocomposite, namely epoxy resin (EP) filled with boron nitride nanosheet (BNNS) are investigated by utilizing molecular dynamics simulation, and the effect of surface functionalization is analyzed. The radial distribution density (RDD) and interfacial binding energy (IBE) are used to explore the s

Revealing the gas-liquid interfacial corrosion mechanism of metals under anodic polarization in molten salts is crucial for the development of metallic anodes for molten carbonate electrolysis. Herein, the effects of operating temperature, gas atmosphere, applied current density and electrolysis time on the gas-liquid interfacial corrosion behaviors of nickel anodes in molten Li2CO3-Na2CO3-K2CO3 were systematically investigated. It was found that the gas-liquid interfacial corrosion of nickel anodes was accelerated with decreasing temperature and increasing CO2 content of gas atmosphere. Three

Adhesives are widely used in our life and industrial world. However, it is difficult to characterize their mechanical properties because those strongly depend on environmental and mechanical conditions such as temperature, humidity or strain rate.

The results show that, in lower rate region (under 1.0 mm/s), the interfacial strength is constant and, in transition region (1.0 to 10 mm/s) the interface strength increased with the peel

Such interfacially confined growth is utilized to grow a ∼300-nm-thick Au/Cu multilayer with thickness of each layer nearly equal to the optimal interfacial width which was obtained from secondary-ion mass spectrometry (SIMS) data.

The need to reduce the cost of components is driving more and more machine elements to operate under mixed lubrication conditions. With higher operating pressures, the lubricant film is becoming thinner and eventually reaches nanometre scales, comparable to the surface roughness. Thus, understanding the mixed lubrication phenomenon is becoming increasingly important. However, the mixed lubrication phenomenon is difficult to capture experimentally and the lubricant additive ZDDP (Zinc Dialkyl Dithio Phosphate) shows its full antiwear character in the mixed lubrication conditions.

Abstract:
AbstractIn the present study, the adjoint method is introduced to the optimisation of the corner cooling element in two baseline cooling designs for a mould cavity, as examples of the Aluminium metal die-casting process. First, a steady thermal model simulating the Aluminium die-casting process is introduced for the two-corner cooling design scenario. This steady model serves as the first iteration of the optimised model using the adjoint method. A dual-parameter objective function targets the interfacial temperature standard deviation and pressure drop across the internal cooling region. For both design cases, multi-iterative deformation cycles of the corner cooling configurations result in optimised designs with non-uniform cross-section geometries and smooth surface finishing. Numerical simulations of the resulting designs show improvements in uniform cooling across the mould/cast interfacial contact surface by 66.13% and 92.65%, while the optimised pressure drop increases coolant fluid flow by 25.81% and 20.35% respectively. This technique has been applied to optimise the complex cooling system for an industrial high-pressure aluminium die-casting (HPADC) tool (Zeng et al. in SAE Technical Paper 2022-01-0246, 2022, [1]). Production line experience demonstrates that the optimised designs have three times the operational life compared to conventional mould designs, providing a significant reduction in manufacturing and operation costs.

Abstract:
AbstractIonic liquids have been considered as promising electrolytes for supercapacitors due to the wide electrochemical stability window. However, water molecules inevitably damage the electrochemical properties of ionic liquids due to the hygroscopic property. This paper reveals the effect of water molecules on the interfacial structure and energy storage performance of ionic liquids using the atomistic simulations. Unlike neat ionic liquids, the Helmholtz region for humid ionic liquids is mainly composed of BMI cations and water molecules. Importantly, water molecules primarily accumulate in the buffer region between BMI cation and graphene electrode, especially at the high negative charges, which is the crucial factor to induce the hydrogen evolution reactions for the decreased electrochemical stability window. More interestingly, the dielectric properties of water molecules in the buffer layer are beneficial for lowering the electric potentials for higher capacitive performance. The differential capacitance of [BMI+][BF4−]/H2O electrolyte exhibits a bell-shaped curve with a maximum value of ~5.0 F/cm2 at 0.75 V. The revealed insights are important for understanding the water effect in ionic liquid-based supercapacitor energy storage.

Abstract:
Abstract Electrochemical impedance spectroscopy (EIS) was used to evaluate the corrosion performance of four high chromium stainless steels and Grade 2 titanium in flowing Arabian Gulf natural seawater. The EIS provided information concerning the changes to the interfacial impedance as a function of exposure time for these alloys. The impedance spectra for all the alloys showed slight changes at the low frequency region over the exposure period. The open-circuit potentials (OCP) of these alloys were also monitored as a function of exposure time. The stainless steel alloys exhibited slight fluc

Abstract:
Molecular dynamics (MD) simulations of liquid-vapor interfaces were performed to determine mean property variations and property fluctuations in the liquid-vapor interfacial region at various reduced temperatures. The interfacial region typically has a thickness on the order of a few nanometers for systems of practical interest. The system’s initial conditions were specified as a bulk liquid region sandwiched between two bulk vapor regions. Simulations were run using a Lennard-Jones 6-12 potential function between the atoms with appropriate parameters for Argon atoms. As the simulation was per

Abstract:
Abstract A general analysis methodology is developed to obtain accurate elasticity solutions of the singular stress fields associated with free edges and interfaces in multilayered structures under thermo-mechanical loads. Approximate solutions based on finite element or variational methods are used to provide traction boundary conditions on a circular path encircling the singularity. The singular elasticity solution of the region interior to the path is then determined in terms of eigenfunction expansion and by using boundary collocation.

Abstract:
This report contains data that demonstrates the scaling of flow regime, pressure drop, and holdup multiphase flow with pipe diameter. In addition, entrance length effects, the onset of liquid entrainment, and interfacial shear modeling at high gas density were studied for purposes of validating multiphase flow design methods. Stratified, slug and annual flow regimes were observed in a 112-foot long 3.5-inch diameter test section. Air, freon, and water were used to represent pipeline fluids.

Abstract:
In the current extension of the work, three additional inspection trials were successfully completed by two NDE vendors, Sonomatic Ltd and Testex, Inc. The Sonomatic inspection team used two advanced ultrasonic techniques, M-skip and Dynamic Response Spectroscopy (DRS). The Testex team used an existing Low Frequency Electromagnetic Technique (LFET) and a recently developed Off-Surface Electromagnetic Technique (OSET). Both electromagnetic tests are complementary. The LFET was designed to scan bare metals as well as through paints and protective coatings. OSET has been specifically developed fo

Abstract:
Systems for registering taxpayers in sub-Saharan Africa are often poorly designed and managed. There are three characteristic problems: the process of registering new taxpayers is not sufficiently targeted on the people and businesses likely to be liable to pay tax; too many (nominal, unproductive) taxpayers are registered; and taxpayer identification (ID) details in the tax register are inaccurate. These problems interact perversely – each exacerbates the others. They will all to a large degree be solved, almost naturally, as a result of: (a) greater digitisation of tax administration general
