The “Nano Information Pyramid” as an Approach to the “No Data, no Market” Problem of Nanotechnologies

Consumers want to know what they buy, retailers have to know what they sell and processors and recyclers need to know what they handle. This applies to ordinary materials but also to products which contain engineered nanomaterials. However, the relevant nanospecific information is often lost somewhere along the value chain. Following vivid discussions during the NanoRegulation Conference, the Innovation Society (St.Gallen) proposes the model of a "Nano Information Pyramid" in order to debate… Continue

MIT Researchers use nanotechnology to repair brain damage and restore vision

Spinal cord injuries, serious stroke and severe traumatic brain injuries affect more than 5 million Americans at a total cost of $65 billion a year in treatment. Is there any hope?



Researchers from MIT and Hong Kong University come to give us hope. The group actually managed to partially restore vision to rodents blinded by damage caused to their brains’ visual system. The secret of success is a tiny biodegradable scaffold invented by MIT bioengineers and neuroscientists. This… Continue

Could A Nanotube-based Drug Prevent Radiation Injury

he Department of Defense has commissioned a nine-month study from Rice University chemists and scientists in the Texas Medical Center to determine whether a new drug based on carbon nanotubes can help prevent people from dying of acute radiation injury following radiation exposure. The new study was commissioned after preliminary tests found the drug was greater than 5,000 times more effective at reducing the effects of acute radiation injury than the most effective drugs currently… Continue

Heat can help chemotherapy work better

Cancer patients whose tumors are targeted with heat treatment as well as chemotherapy are more likely to stay alive and cancer-free for longer than those who receive only chemotherapy, researchers said on Tuesday.



The finding suggests it may be possible to cut the dose of chemotherapy drugs by using heat, although more research is needed to establish this, they said.



German researchers looking at cancers in soft tissues such as muscle, fat and tissue around the joints,… Continue

Atomic layer graphene as saturable absorber for ultrafast pulsed lasers

http://www3.ntu.edu.sg/home2006/zhan0174/AFM.pdf



The optical conductance of monolayer graphene is defined solely by the fine structure constant, α = e2/ћc (where e is the electron charge, ћ is Dirac’s constant and c is the speed of light). The absorbance has been predicted to be independent of frequency. In principle, the interband optical absorption in zero-gap graphene could be saturated readily under strong excitation… Continue

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
