Nanoparticles reveal mechanisms of cancer cell growth in whole cells

Healthy cells are renewed by dividing and dying off, but cell division in cancer cells goes unchecked because natural cell death is suspended. This happens because too many receptors for the growth factor EGF which are found on the surface of the cell join together to form pairs. These pairs start a signal chain into the cell, culminating in unrestricted growth. Now, nanoscientists have for the first time been able to show this pairing in human cancer cells on individual receptors using gold nanoparticles.

A self-correcting crystal may unleash the next generation of advanced communications

Researchers from the National Institute of Standards and Technology (NIST) have joined with an international team to engineer and measure a potentially important new class of nanostructured materials for microwave and advanced communication devices. Based on NIST's measurements, the new materials - a family of multilayered crystalline sandwiches - might enable a whole new class of compact, high-performance, high-efficiency components for devices such as cellular phones.

Understanding what makes a thin film solar cell efficient

Scientists have developed a new technique for manufacturing high-efficiency, flexible, thin film solar cells from CIGS (copper indium gallium di-selenide) semiconductors. This has enabled them to achieve an efficiency of 20.4 percent for the conversion of sunlight into electrical energy. As the solar cells are deposited onto plastic foils, they could be produced on an industrial scale using cost-effective roll-to-roll manufacturing.
