Solutions of the cationic amino-acid arginine (Arg+) in contact with a phospholipid monolayer are investigated by molecular dynamics simulations. The results show that Arg+ binds strongly to the lipid/water interface, with adsorption free-energies ranging from -43.8 to ...

In this paper, we propose a scenario framework that could provide a scenario " thread" through the different climate research communities (climate change - vulnerability, impact, and adaptation - and mitigation) in order to support assessment of mitigation and adaptatio...

In recent years manufacturing industries have moved towards Smart Manufacturing, to achieve improved efficiency and production targets. Part of this innovation of current processes includes digitisation and improving access to machine information, usually through the in...

Abstract The energy harvesting performance of a flapping airfoil is studied through discrete vortex model. Results are obtained for a thin flat airfoil that undergoes a sinusoidal flapping motion for reduced frequencies of k = fC/U∞ = 0.06–0.16 where f is the heaving fr...

Human land use and climate change are regarded as the main driving forces of present-day and future species extinction. They may potentially lead to a profound reorganisation of the composition and structure of natural communities throughout the world. However, studies ...

The world in general and cities in particular face tremendous challenges at the environmental, social, economic and institutional levels. Currently, cities need to be sustainable and smart. As our better knowledge, most of the literature explores the concept of smart ci...

Using coarse-grained structural model for two-headed dynein and a hybrid of molecular dynamics and Monte Carlo simulations, we explore the mechanical properties of dynein stepping, including: a structurally biased search for binding sites, step-size distribution, mechan...

Abstract Nowadays, the energy crisis is one of the most critical challenges facing countries. To deal with this crisis, instead of independently optimizing each of the energy carriers (electricity, gas, heat etc.), all carriers are considered simultaneously by a concept...

Regulating the states of hydrogen bonds in ionic liquids (ILs) is an effective way to improve their catalytic performance. In this paper, disulfonic-functionalized acidic ionic liquids (DSFAILs) were synthesized successfully, including novel SO3H-functionalized binuclea...

The results of an evaluation of different mixed surfactant and alkaline-enhanced surfactant systems for enhanced oil recovery are described. Several mixed surfactant systems have been studies to evaluate their oil recovery potential as well as improved adaptability to d...

Electrochemical water splitting driven by clean and sustainable energy sources to produce hydrogen is an efficient and environmentally friendly energy conversion technology. Water splitting involves hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), ...

The fluctuations of wind power impact the stable operation of a power system as its penetration grows high. Energy storage may be a potential solution to suppress these fluctuations and has drawn much attention in recent years. As the time scale of wind power fluctuatio...

We demonstrate a thousand-fold enhancement of second-harmonic generation in an all-dielectric silicon nitride (SiN) resonant waveguide grating compared to a flat SiN film. The strong second-harmonic output measured at 532 nm results from the combination of the enhanced ...

The vegetable oil, fats and their biodiesel suffer with the drawback of deterioration of its quality during long term storage unlike petroleum diesel. The oxidation and thermal stability of two biodiesels of different origins, viz. palm oil derived biodiesel and used co...
