NIST demos industrial-grade nanowire device fabrication
In the growing catalog of nanoscale technologies, nanowires-tiny rows of conductor or semiconductor atoms-have attracted a great deal of interest for their potential to build unique atomic-scale electronics.   view more (2007-10-29)

Concrete less sensitive for cracks than previously thought
Reinforced high-strength concrete can crack due to stresses that develop during the hardening process. However, this has been found to be surprisingly less quick than previously thought. Due to Dutch research, extra steps during the hardening process can be omitted. This will result in cheaper... view more (2003-03-21)

Nanogenerator provides continuous power by harvesting energy from the environment
Researchers have demonstrated a prototype nanometer-scale generator that produces continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow.   view more (2007-04-06)

Scientists demonstrate method for integrating nanowire devices directly onto silicon
Applied scientists at Harvard University in collaboration with researchers from the German universities of Jena, Gottingen, and Bremen, have developed a new technique for fabricating nanowire photonic and electronic integrated circuits that may one day be suitable for high-volume commercial... view more (2008-05-09)

Zinc can help in the treatment of pneumonia (pp 1683)
The addition of zinc to standard antimicrobial treatment may accelerate recovery from pneumonia, say researchers in this week's issue of THE LANCET. Pneumonia is a leading cause of mortality and morbidity in children less than five years old. Zinc is reported to prevent pneumonia, and to prevent... view more (2004-05-19)

Nanowire generates power by harvesting energy from the environment
As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy... view more (2007-09-28)

Problem: Implant Infection. Solution: Nanotech Surfaces
Orthopaedic implants help millions of Americans stay active. But these medical devices are prone to infection, forcing patients back to surgery for repair or replacement. Now, for the first time, a team of engineers has shown that zinc or titanium oxide nanosurfaces can reduce the presence of... view more (2006-07-10)

Silicon nanowires upgrade data-storage technology
Scientists at the National Institute of Standards and Technology (NIST), along with colleagues at George Mason University and Kwangwoon University in Korea, have fabricated a memory device that combines silicon nanowires with a more traditional type of data-storage.   view more (2007-06-11)

Zinc deficiency an underestimated problem
Children in Java have better resistance to disease if they take not only vitamin A and iron supplements but also extra zinc. NWO nutrition researchers have shown that shortages of vitamin A and the two minerals often occur together. Zinc deficiency appears to be a problem which has so far not been... view more (2001-07-26)

Zinc supplements could help treat ADHD
As attention deficit hyperactivity disorder (ADHD) affects around 1 in every 25 school-aged children, managing this condition is of huge social importance. An article published in BMC Psychiatry this week shows that zinc supplements could increase the effectiveness of stimulants used to treat... view more (2004-04-06)

Warning over nitric oxide for lung injury patients
Use of nitric oxide in patients with acute lung injury does not improve survival and may cause harm, warn researchers in a study published on bmj.com today.   view more (2007-03-23)

Researchers think pink to produce 'green' solar energy
When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers. Scientists here have developed new dye-sensitized solar cells, that get their pink color from a mixture of red dye and white metal oxide powder in materials that... view more (2007-07-31)

Zinc Lozenges an Ineffective Treatment for Colds
Despite 20 years of research, the benefits of zinc lozenges as a therapy for the common cold have not been proven.   view more (2007-08-03)

Prenatal Zinc Supplementation Could Impair Childhood Mental Development
Authors of a study in this week's issue of THE LANCET caution that the provision of zinc supplementation to pregnant women in developing countries could impair the early mental development of their children. Zinc deficiency is common in developing countries due to a diet that is low in animal... view more (2002-07-24)

Nanowire coating for bone implants, stents
