Russian researchers to study the silicon particles effect on cells

Nanostructured silicon surfaces and silicon nanoparticles slow down the division of stem and cancer cells, and the combination of nanoparticles and ultrasound kill the cells. The research has been conducted at the Physics department of Moscow State University, the Institute of Theoretical and Experimental Biophysics, Russian Academy of Sciences, the I.M. Sechenov First Moscow State…

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.…

Russian researchers suggest precipitating nickel on carbonic nanotubes

Nickel nanoparticles are used as a catalyst to produce various substances — for example, synthetic hydrocarbons. Broad use of this inexpensive catalytic metal is limited by the fact that researchers have no effective method of generating nanoparticles of similar structure and of closely varied sizes.

Experts at the Nanotechnologies and Nanomaterials Research Centre at Tambov Derzhavin State University have…

Nanomaterial purity is vital for bacterial health

Researchers at the University of Orenburg have tested the effect of various carbon nanoparticles on bacteria. It was discovered that the bacteria-growth-inhibiting properties of nanotubes declined as the quality of purification lowered; the bacteria were neutral towards fullerenes unless the latter were modified by amine groups.…

Nanoparticles rush to disordered heart

Experiments on rats carried out by Russian researchers have demonstrated that silica nanoparticles can be used to deliver drugs to the heart in case of myocardial ischemia.

One of the most promising directions in…

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.…

Chlorella and daphnids accumulate nanotitanium

Russian researchers have developed a method for assessing biological accumulation of nanoparticles in planktonic organisms, and have demonstrated that algae and seed shrimps intensively accumulate titanium dioxide particles.…

Dust in thermonuclear reactors

In the course of plasma magnetic traps’ operation, erosion their walls’ occurs, and nano-dimensional films and dust particles are formed. Researchers at the Russian Scientific Center “Kurchatov Institute” assert: the dust can favorably influence the reactor’s operation.

A tokamak (a toroidal chamber with magnetic coils) is a closed magnetic trap intended for high-temperature plasma creation and confinement. Controlled…

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
