New research shows that exposing polymer molecular sieve membranes to ultraviolet (UV) irradiation in the presence of oxygen produces highly permeable and selective membranes for more efficient molecular-level separation, an essential process in everything from water purification to controlling gas emissions.
Scientists have been able to show ways in which we can markedly improve drug targeting of solid tumors, using tiny 'biosensors' along with new advanced imaging techniques. In real time and in three dimensions, these technologies can show us how cancers spread and how active cancer cells respond to a particular drug.
Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures - including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals.
New, more efficient drug formulations designed to treat illnesses through skin applications - thus avoiding serious side effects associated with oral drug-taking - have been developed by a student at the Hebrew University of Jerusalem. The method is based on utilizing skin-permeable proteins that are inserted into nano-structured gels.
Mobile phones that bend, self-powered nanodevices, new and improved solar cell technology and windows that generate electricity are but a few of the potential products from the union of semiconductors and graphene.
Researchers at Sandia National Laboratories have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate, findings that could lead to better performance in lithium-ion batteries in electric vehicles, medical equipment and aircraft.
Now in its fourth year, Nanoweek will celebrate the importance of nanoscience to the Irish economy; the excellence of nanoscience research within our universities, and look to grow public awareness of a technology which is fundamental to medicine, communications, pharmaceuticals, energy and transport among other industries.
A new study found that the shape of nanoparticles can enhance drug targeting. According to this study, rod-shaped nanoparticles - or nanorods - as opposed to spherical nanoparticles, appear to adhere more effectively to the surface of endothelial cells that line the inside of blood vessels.
Scientists at Rice University and Oak Ridge National Laboratory (ORNL) have advanced on the goal of two-dimensional electronics with a method to control the growth of uniform atomic layers of molybdenum disulfide.
The research team demonstrated a novel method to epitaxially synthesize structurally and compositionally homogeneous and spatially uniform ternary InAsyP1-y nanowire on Si at wafer-scale using metal-organic chemical vapor deposition (MOCVD). The high quality of the nanowires is reflected in the remarkably narrow PL and X-ray peak width and extremely low ideality factor in the InAsyP1-y nanowire/Si diode.
Researchers report the design and fabrication of the smallest optical device, capable of detecting and sensing individual biomolecules at concentrations that are similar to those found in the cellular context.
