Engineers have developed a new method for creating high-performance membranes from crystal sieves called zeolites; the method could increase the energy efficiency of chemical separations up to 50 times over conventional methods and enable higher production rates.
BASF and IMEC, Europe's leading independent nanoelectronics research center, have announced that they are extending their joint development program. The process chemicals which the two partners plan to develop as part of their extended work together will enhance the performance of cleaning chemicals in the production of semiconductors. Research will also focus on reduction of process complexity and the number of production steps.
Researchers grappling with the problem of developing the most fuel-efficient electric cars are using micro-jet turbine engines and 'supercapacity' batteries to help energy-conscious consumers drive further.
A revision to an important ASTM nanotechnology standard incorporates a large-scale interlaboratory study that took place in 2008. The revised standard, ASTM E2490, Guide for Measurement of Particle Size Distribution of Nanomaterials in Suspension by Photon Correlation Spectroscopy (PCS), is under the jurisdiction of Subcommittee E56.02 on Characterization: Physical, Chemical and Toxicological Properties, part of ASTM International Committee E56 on Nanotechnology.
Nanoparticle delivery of diphtheria toxin-encoding DNA selectively expressed in ovarian cancer cells reduced the burden of ovarian tumors in mice, and researchers expect this therapy could be tested in humans within 18 to 24 months.
