Bony nanotechnology

When people are born no spare parts are readily available for them. Soft tissue regeneration occurs quite fast but what about bone recovery? It was proved that implants — artificial bone replacements — were in use as long ago as some time BC. A piece of a mandibula of an Inca (6th century BC) was found in modern Honduras, around the De Los Muertos plateau, bearing three dental implants made of sea mussel shells. A female skull belonging to the 1st century BC, with a…

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.…

NANOTIRNO

The lubricating environmant in technical Tribals-systems is a dynamic multi-phase system that consists of liquid, solid and gaseous components. Solid particles have different origins and unknown influence on the behavior of Tribals systems. Some of them are product of wear, while others are product of oil oxidation or are soaked from the outside while in contact with the Tribals systems. Solids are placed in lubricating environment for a specific purpose - to act as…

A new structural model will help to sort out nanotubes

Researchers at the Kazan State Technical University named after A.N. Tupolev  have developed mathematical models that describe structure of various nanotube types. They allow to adjust existing theoretical ideas and design methods for various nanotube characteristics. As model application experience is accumulated, these models can help to forecast nanotube properties as well as to develop their automatic sorting methods. The work was…

Laser hyperthermia to fight against tumors

Laser waves focused on the tumor area can damage cancer cells and blood vessels feeding them. The process becomes more efficient if nanoparticles are preliminary introduced into the tumor. At the conference “Nanotechnologies in Oncology in 2010”, Russian oncologists explained how laser irradiation is absorbed by nanoparticles, what particular nanoparticles should be used and…

Nanoparticles are able to deliver drugs to the brain

The majority of drugs do not penetrate from blood into the brain because of the hematoencephalic barrier existing between them. This creates a lot of difficulties for brain tumor treatment. Russian researchers have developed a system for drug delivery into the brain with the help of nanoparticles and demonstrated its efficiency on laboratory animals.…

Nanostructures based on precious stones

Researchers at the Ioffe Technical Physical Institutehave developed a new method of synthesising composite materials from synthetic opal and vanadium oxides. Such materials have unusual optical properties. Previously, they were generated by depositing vanadium oxides (V2O5 and VO2) from a solution, but in their latest work the researchers demonstrated the greater effectiveness of…

Precise method for nanostructure analysis

Specialists at the A.F. Ioffe Institute of Applied-Physics (Russian Academy of Sciences) have developed a new methodology for nano-dimensional heterostructure composition analysis. Along with the composition, the depth of layer occurrence is also identified. Experimental check of the methodology has proved that the data obtained through it on semiconductor structure constitution well agrees with measurement results achieved by other method, the data having low…

Carbon dioxide laser to create nanoparticles of predetermined size

Physicists from Yekaterinburg have generated yttrium-aluminum-garnet nanopowder using the laser-induced evaporation method. The powder with particles sized about 10 nanometers was used to create optic ceramics with a high infrared light transmission factor.

The laser-induced evaporation method also known as laser ablation or laser spark is based on removing a substance from the…

Self-organizing nanotechnologies control metallic material properties

Andrey Oksogoev at the Institute of High Technologies (Ulan-Ude) has carried out an experiment that proves assumptions made earlier. Research of S.P. Kurdumov’s school dealt with energy division into thermal and nonthermal components upon changes in the environment structure. This possibility is the most important objective for establishing self-organizing nanotechnologies.…

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
