Quantum Dots - What's it about?

It's all about Quantum Materials Corp. (OTCQB:QTMM) a nanotechnology company that can make copious amounts of quantum dots that the average person doesn't understand, know if you can see them with…

Silicon Carbide Quantum Dots for bioimaging

1-5 nm SiC nanocrystals were tested in vitro. The cytotoxic properties of the SiC QDs based on alamarBlueTM assay cells were studied. The presence of the QDs dots does not affect cell growth in a wide concentration range. Two-photon excitation showed significant response from SiC nanocrystals that were injected into hippocampal CA1 pyramidal cells.…

Electronic properties probed by scanning tunneling spectroscopy: From isolated gold nanocrystal to well-defined supracrystals

Scanning tunneling microscopy and spectroscopy at 5 K have been used to determine the electronic properties of 7-nm dodecanethiol-passivated Au nanocrystals in three different configurations: isolated nanocrystal, self-organized thin films (few nanocrystal layers), and large three-dimensional well-defined thick films (over 30 nanocrystal layers) called supracrystals. The electronic properties of both thin and thick well-ordered supracrystals are analyzed in scanning tunneling spectroscopy…

The structure of growing nanocrystals is possible to manage

Vertical nanocrystal whiskers or nanowiskers are one-dimensional crystals that look like rods or threads several nanometers in diameter. The rods are often cultivated using the elements of the third and fifth groups of the periodic table. The most common nanocrystals of the third and firth groups are gallium arsenide and indium phosphide. These semiconducting materials present competition to silicon in the electronics field as diodes and transistors built using them are faster in operation.…

Light instead of temperature: nanocrystals have become more accessible

Russian researchers have suggested a new method to form crystalline nanostructure of the Fe-Cu-Nb-Si-B alloys. The nanostructures obtained under the action of gas discharge optical radiation possess better magnetic and mechanical characteristics as compared to their analogues produced via temperature methods.…

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu

Dr. András Paszternák, founder of Nanopaprika
