Archaeological evidence suggests that glass was first made in the Middle East sometime around 3000 B.C. However, almost 5,000 years later, scientists are still perplexed about how glassy materials make the transition from a molten state to a solid. Richard Wool, professor of chemical engineering at UD, thinks he has the answer.
Europe's research ministers adopted conclusions on Alzheimer's, the European partnership for researchers and responsible nanotechnology research at their Competitiveness Council meeting in Brussels on 25 and 26 September.
The 2nd International Festival of NanoArt organized by NanoArt21 (www.nanoart21.org) will be hosted in Stuttgart, Germany by NAHVISION Institute for International Culture Exchange, between November 1st and November 30th, 2008.
Dutch researcher Jeroen Bominaar has developed a new measurement technique based on following molecules in a (turbulent) airflow. Its main advantage is that no measuring instruments or small particles, such as glass beads, need to be inserted into the flow.
The Camille and Henry Dreyfus Foundation announces the establishment of the Dreyfus Prize in the Chemical Sciences to recognize an individual for exceptional and original research in a selected area of chemistry that has advanced the field in a major way.
he Nanoethics Group today announced that it will make two presentations at the upcoming 'Environmental Nanoparticles: Science, Ethics, and Policy' conference on November 10-11, 2008, hosted by the acclaimed Delaware Biotechnology Institute and University of Delaware.
How heavy or how big can an object be before losing its quantum properties and obeying to the laws of classical physics? This question drives many research groups all around the globe. Answers still remain to be given as currently there are no systems which allow observing the expected tiny signatures of quantum effects in macroscopic objects.
Singapore's Institute of Bioengineering and Nanotechnology (IBN) has invented a unique user-friendly gel that can liquefy on demand, with the potential to revolutionize three-dimensional (3D) cell culture for medical research.
Bacterial nanoinjectors transport proteins across three membranes: the inner and outer bacterial membranes plus the host cell membrane. Nanoinjectors essentially connect the bacterial cell contents with the host cell's and form a conduit for delivering bacterial effector proteins into the host. Once inside, these proteins reprogram the host's cellular functions to promote survival, growth, and bacterial propagation
Until recently, scientists couldn't create the nanoparticles without producing synthetic chemicals that had negative impacts on the environment. A new method, created by a University of Missouri research team, not only eliminates any negative environmental impact, but also has resulted in national and international recognition for the lead scientist.
Researchers at the University of Illinois at Urbana-Champaign have developed a new process for making nanoparticles that relies on paclitaxel itself to serve as the initiator that triggers polymer synthesis. The result is not only a stable nanoparticle formulation of paclitaxel but also one with very high and very controlled amounts of drug being incorporated in the nanoparticle.
Using a combination of polymers that respond to temperature, a research team at the University of Utah has developed a multifunctional nanoparticle that can image tumors using ultrasound and simultaneously deliver cell-damaging energy and anticancer drugs to those tumors. In addition, these nanoparticles appear to act specifically on tumors and not on healthy tissue.
In an effort to overcome the drug resistance that often occurs in cancer, a team of investigators has developed a nanoparticle made of a blend of polymers that first releases a powerful anticancer drug and then delivers an agent that tricks a drug-resistant cell into committing suicide. Now, tests in mice with human breast cancer have shown that these blended nanoparticles are effective in maintaining high levels of both drugs in the vicinity of tumors.
