The main purpose of this work was to show that by using low‐pressure plasma it is possible to obtain platinum nanoparticles with uniform size and shape and then apply these nanoparticles in order to evaluate the proces...

Amid escalating global climate concerns, the reliance of the transportation sector on high-carbon fossil fuels urgently demands sustainable alternatives. Hydrogen has emerged as a potent solution because of its zero-emis...

Background: Cancer stem cells are important for the development of many solid tumors. These cells receive promoting and inhibitory signals that depend on the nature of their environment (their niche) and determine cell d...

ABSTRACT Bio‐inspired optimisation methods have been widely applied to complex real‐world problems, particularly in low‐carbon power and energy systems, where optimisation tasks often involve high‐dimensional, co...

Las celdas de combustible biológicas son dispositivos bio-electroquímicos, donde generalmente el ánodo (pero a veces el cátodo, o ambos) contiene microorganismos capaces de generar y mantener un gradiente electroquí...

High-power density output in enzymatic fuel cells is a key feature to reduce the size of self-powered implantable medical devices. Electron transfer mediated through redox polyelectrolytes allows the transport of electro...

Energy consumption and the utilization of sustainable energy sources are of great importance for the economic independence and environmental stability of nations. Turkey, as a country heavily dependent on energy imports,...

Abstract The dual pressures of climate change and industrial water scarcity demand integrated solutions that jointly decarbonize power supply and reduce freshwater dependency. This study presents a site-specific, techno-...

Abstract In polymer electrolyte fuel cells (PEFCs), temperature gradients can exert a substantial influence on cell performance and durability. Monitoring these gradients without perturbing fuel cell operation is one of ...

The amorphous reduction product of the oxide ion conductor La2Mo2O9 was previously shown to be a good, sulphur-tolerant, anode material for solid oxide fuel cell devices (X. C. Lu, J. H. Zhu, J. Electrochem. Soc., 2008, ...

Abstract Hydrogen generation from renewable energy sources allows balancing the intermittent nature of solar and wind power. The chemical energy stored in hydrogen can be efficiently converted back to electricity using f...

Nafion exhibits one of the highest proton conductivity at room temperature and it is the standard electrolyte of proton exchange membrane fuel cells (PEMFC). However, the temperature dependence of ionic conductivity of N...

With ever increasing concern on energy diversification, energy efficiency and environmental protection, electric vehicles (EVs) including the pure EV (PEV), hybrid EV (HEV) and fuel-cell EV (FEV) are becoming attractive ...

Superionic conductors (SICs) exhibit liquidlike ionic diffusivities while maintaining a periodic crystalline lattice, making them promising candidates for applications in fuel cells, solid-state electrolytes, and thermoe...

Trypanosoma cruzi, the etiological agent of Chagas disease, has a digenetic life cycle. In itspassage from the insect vector to the mammalian host, and vice versa, it must be preparedto cope with abrupt changes in enviro...

Abstract Androgen receptor (AR) is a therapeutic target for prostate cancer. Despite effectively targeting its folded ligand-binding domain (LBD), resistance ultimately develops by mechanisms involving reactivation of AR...

Abstract. During each voyage, the vessel's traction capacity decreases due to the gradual degradation of the characteristics of the propulsion complex. This process is influenced by factors such as fouling of the vessel'...

L-arginine (ARG) availability is a critical determinant of macrophage antimicrobial capacity, as it fuels nitric oxide production and other immune effector pathways essential for restricting Mycobacterium tuberculosis (M...

Abstract. The pumping activity permanently carried out by the heart requires a constant energy supply that is derived mainly from fatty acids and, to a lesser extent, from glucose and lactate. The Krebs cycle plays a cen...
