Fuel cells (FCs) have gained a prominent position in recent years within the scientific community and energy market as an alternative to mitigate inherent problems production based on fossil fuels such constant reduction of nonrenewable resources, greenhouse gas emissions, climate change. The versatility high temperature (HT) proton exchange membrane (PEM) FCs, together with their efficiency po...

In this paper, we present a novel quantitative description of intracellular and t-tubular Ca dynamics in a model of rat cardiac ventricular myocyte. In order to simulate recently published data, the model incorporates t-tubular and peripheral dyads and intracellular subspaces, segmentation of the t-tubular luminal volume, reformulation of the inactivation properties of t-tubular and peripheral ...

Carbon nanotubes have attracted considerable attention since their discovery,[1] and have recently been the focus of intensive investigations. Studies have revealed that nanotubes exhibit extraordinary electronic properties.[2,3] Nanotubes have been shown to ignite upon exposure to short-range flashes of light,[2] and recently ultrafast carbon-nanotubebased transistors have been shown to outper...

This communication describes the co-assembly of polydopamine spheres, either bare or coated with Fe3O4 magnetic nanoparticles, with the short aromatic peptide diphenylalanine. The combination of polydopamine particles and diphenylalanine generated tubular structures decorated with adhesive spherical particles, while the co-assembly of the polydopamine spheres coated with magnetic Fe3O4 nanopart...

Tissue engineering is a promising technological approach to addressing shortages of organs available for transplantation. Tissue engineering aims to create functional organs by using biomaterials and cells. Artificial tissues can be implanted in patients to recover tissue functions that were lost due to severe injury, disease. However, it is difficult to construct functional organs because tiss...
