What is a Pecha Kucha?. Pecha Kucha is a concentrated pitch where the participants present exactly 20 slides at a rate of 20 seconds per slide. The entire presentation lasts 6 minutes lung abscesses are most often caused by which of the following 40 seconds. You may find information about the Pecha Kucha format and how to prepare one here and here.

Be sure to check out the examples for inspiration. Thanks to sponsorship from NTNU Nano, there is no participation fee, but you will need to register your attendance. Read more about the programme and registration here.

The research, supported by the Lung abscesses are most often caused by which of the following program for Enabling Technologies, could help to pinpoint the very beginnings of neurodegenerative diseases. By connecting lung abscesses are most often caused by which of the following nodes together the researchers can mimic the connectivity inside the human brain.

But Sandvig is keen to stress that these neural networks are not in any way real brains. They saw that, in the network with the mutation, neurons grew and formed connections in a markedly different way, and displayed different electrical activity, to the healthy network. The interface also allowed the researchers to look at the connectivity within the nodes as well as between them. Studying these brain changes in a neural network has advantages over studying them in animals, though each method can inform the other.

By providing new insights into how our brains change in the early days of neurodegenerative disease, real life neural networks could set us on a path to new understanding, and perhaps, eventually, even new treatments. Researchers from NTNU are shedding light on magnetic materials at small scales by creating movies with the help of some extremely bright x-rays.

The work, partially funded by NTNU Nano and the Research Council of Norway, was published in the journal Physical Review Research. The tiny square magnets, created by NTNU PhD candidate Einar Digernes, are just two micrometers wide and split into four triangular domains, each with a different magnetic orientation pointing clockwise or anti-clockwise around the magnet. The researchers took their micromagnets to an 80m-wide donut-shaped synchrotron, known as BESSY II, in Berlin, where electrons are accelerated until they are travelling at almost the speed of light.

Those fast moving electrons then emit extremely bright x-rays. Because electrons travel around the synchrotron in bunches separated by two nanoseconds, the x-rays they emit come in precise pulses. By stitching these snapshots together, the researchers can essentially create a movie showing how the micromagnet changes over time. With the help of the STXM, Folven and his colleagues disturbed their micromagnets with a pulse of current that generated a magnetic field, and saw the domains change shape and the vortex core move from the centre.

To solve the substrate problem, the researchers buried their micromagnet under a layer of carbon to protect its magnetic Ibritumomab Tiuxetan (Zevalin)- FDA. Then they carefully and precisely chipped away the substrate underneath with a focused beam of gallium ions until only a very thin layer remained.

They also created computer simulations to better understand what forces were at work. As well as advancing our knowledge of fundamental physics, understanding how jamaica works at these length and time scales could be helpful in creating future devices. Magnetism is already used for data storage, but researchers are currently looking for ways to exploit it further.

The magnetic orientations of the vortex core and domains of a micromagnet, for example, could perhaps be used to encode information in the form of 0s and 1s. The researchers are now aiming to repeat this work with anti-ferromagnetic materials, v com k the net effect of the individual magnetic moments cancels out.

Despite that challenge, Folven is optimistic. As sunlight filters through a forest canopy, chlorophyll is hard at work capturing the energy of photons. Inspired by nature, researchers at NTNU are working on light-capturing dyes for solar cells to generate electricity. In those silicon solar cells, light hits one of two semiconductor layers and frees up electrons to jump between the layers.

A dye-sensitised solar cell (DSSC) works in a similar way, but one of the semiconductor layers is replaced with a photosensitive dye that absorbs the light and releases electrons instead. Dye-sensitised solar cells tend not to be as efficient at converting light into electricity as their silicon counterparts. But they work in low light conditions, and can be transparent and lung abscesses are most often caused by which of the following, so are better suited to some applications.

To harvest light a dye needs to act as an electron donor and an electron acceptor. By adding something in-between the donor and acceptor, chemists are able to increase the amount of light the cell harvests. Thiophenes are electron-rich, so would be expected to increase the light harvesting properties of the dye, he says. And recent experiments show that they do: the dye with the most thiophenes was the one that harvested most light.

In his experiments, Almenningen found that though it absorbed the most light, the dye with the most thiophenes actually made the least efficient solar cell. He and his colleagues hope to find a way to avoid those counterproductive effects and take advantage of the improved light collection. Their next step is to try modifying the dye chemically so the electrons can only go in one direction. If this is successful, it could lead to more efficient solar cells. Finding a way to increase the efficiency of DSSCs is one of the roadblocks to widespread use.

One promising avenue for DSSCs your be to integrate them into buildings to lung abscesses are most often caused by which of the following the dimmer light that is typically found indoors.
