Nanoparticles are agglomerates of particles that consist of a few to several hundred atoms or molecules. So they are in size somewhere between atoms / molecules and solids. Their physical and chemical properties are intermediate between those of these two extremes and are in wide ranges designable as a function of the number of particles [...]
In women with dense breasts an ultrasound examination may improve early diagnosis Kefah Mokbel, an expert from the London Breast Clinic told the “Daily Telegraph” that women with dense breasts should undergo, in addition to the already recommended mammography, ultrasound examination also: “Women with higher breast density 75% have a risk of cancer 4 times [...]
While refined its novel method for cable manufacturing nanoscale, Chemists at the National Institute of Standards and Technology ( NIST English ) United States found an unexpected gift : a new way to create nanowires that produce a light similar to light-emitting diode (LED). These “nano -LED” may one day put their light output capabilities [...]
What is currently in front of and on the coasts of the Gulf of Mexico happening is bizarre, not to put into words, just terrible. Since the Explosion of the platform, ” Deep water Horizon ” on 20 April flow from the borehole further large quantities of oil into the sea. BP tries to indicated [...]
Researchers at JILA have demonstrated the use of infrared laser light to heat the water quickly and with precision “nano tubs “- small sample containers – for microscopy studies of the biochemistry of individual molecules and nanoparticles. JILA technique is faster, more controllable , and less prone to damage expensive optical or make an accidental [...]
Using ” nanoexplosiones ” chemicals that make small holes in the protective membrane of the cells, researchers have demonstrated a new technique to deliver therapeutic small molecules , proteins and DNA directly in living cells. activated carbon nanoparticles by laser light trigger bursts of small explosions that open holes in cell membranes allow sufficient time [...]
