An Efficient Bicomponent TiO2/SnO2 Nanofiber

In this communication we demonstrate that the electrospinning process with a side-by-side dual spinneret can be a simple approach for fabricating bicomponent TiO2/SnO2 nanofibers with controllable heterojunctions Specifically both of the TiO2 and SnO2 components in the nanofibers are fully exposed to the surface This morphology fully utilized the photogenerated holes and electrons during

Structural and Functional Fibers

Side-by-side geometry fibers have also been produced with electrospinning In one example one side of the fiber is polyvinylpyrrolidone K60 (PVP K60) and the other side of the fiber is ethyl cellulose (EC) and both sides contain the drug ketoprofen The side with PVP K60 has a very rapid drug release rate whereas the EC side has a relatively slow drug release rate By blending PVP K60 into

Building lightweight structures with carbon‐fiber

In comparison to fiber‐reinforced concrete which is produced by adding fibers with a length of 10–100 mm to the mixture the FRP bars and textile reinforcement elements can be placed in the regions where tensile stresses occur and reinforcement is required The elements have a tensile strength of up to 300 MPa if natural fibers are used up to 1 600 MPa if AR‐glass fibers are used up

Nonwovens: Current Trends Opportunities

The fiber size after splitting is dependent on the diameter of the original fiber the number of segments and the spinning parameters There are a few limitations to the segmented pie structure However wedged shaped fibers formed during the splitting tend to pack densely and often this may lead to low tear resistance A hybrid structure composed of two or more bicomponent fibers can lead to

Janus particles: from concepts to environmentally friendly

Janus particles represent a unique group of patchy particles combining two or more different physical or chemical functionalities at their opposite sides Especially individual Janus particles (JPs) with both chemical and geometrical anisotropy as well as their assembled layers provide considerable advantages over the conventional monofunctional particles or surfactant molecules offering (a
