Elevated-temperature (100~200 °C) polymer electrolyte membrane (PEM) fuel cells have many features, such as their high efficiency and simple system design, that make them ideal for residential micro-combined heat and power systems and as a power source for fuel cell electric vehicles. A proton-conducting solid-electrolyte membrane having high conductivity and durability at elevated temperatures...

Using of nanocomposite membranes composed of polymer and inorganic nanoparticles is a novel method to enhance gas separation performance. In this study, membranes were fabricated from polyester (PE) containing silica (SiO2) nanoparticles and gas permeation properties of the resulting membranes were investigated. Morphology of the membranes, SiO2 distribution a...

Giant polymersomes are versatile and stable biomimetic compartments that ideal for building cell-like systems. However, the transport of hydrophilic molecules across membrane, which controls function systems, is limited by low permeability polymeric bilayers. Therefore, mechanisms to control necessary create functional Here, we describe design giant equipped with spiropyran-based modulators. Ph...

Polymeric multilayer capsules have emerged as a novel drug delivery platform. These capsules are fabricated through layer-by-layer sequential deposition of polymers onto a sacrificial core template followed by the decomposition of this core yielding hollow capsules. The resulting nanometer thin membrane is permselective, allowing diffusion of water and ions but excluding larger molecules. Moreo...

Permporometry IS a method by which the characterlstlcs of the mterconnectmg ‘active’ pores of an ultrafiltration membrane can be measured It 1s these ‘active’ pores that are responsible for the actual membrane performance Apphcatlon of permporometry on different membrane types, including ceramic as well as polymeric membranes, shows that the method can provide obJectwe mformatlon on the ‘active...
