Physical adsorption is a technique used to characterize the surface and pore features of solids, that is, the materials texture. The adsorption isotherm generated by the Physical Adsorption technique enables one to characterize a solids' texture by determining its surface area, porosity, and total pore volume.
Using a chemical trick that allows them to change the acidity of a solution almost instantly, a team at the National Institute of Standards and Technology (NIST) has demonstrated a simple and effective technique for quantifying how the stability of nanoparticle solutions change when the acidity of their environment suddenly changes.
As part of its ongoing series of live webinars on 3D, non-contact surface profilometry, Veeco Instruments Inc. will be hosting a free online seminar on 'Non-Contact, 3D Optical Surface Profilometry for Ophthalmic Manufacturing'.
Researchers have developed a method to combine two substances that individually have generated interest for their potential biomedical applications: a phospholipid membrane 'bubble' called a liposome and particles of hydrogel, a water-filled network of polymer chains. The combination forms a hybrid nanoscale particle that may one day travel directly to specific cells such as tumors, pass easily though the target's cell membrane, and then slowly release a drug payload.
After running a series of complex computer simulations, researchers have found that flaws in the structure of magnetic nanoscale wires play an important role in determining the operating speed of novel devices using such nanowires to store and process information.
Researchers at Oregon State University and the Pacific Northwest National Laboratory have discovered a new way to apply nanostructure coatings to make heat transfer far more efficient, with important potential applications to high tech devices as well as the conventional heating and cooling industry.
Im Dezember 2010 treffen sich Experten aus der ganzen Welt auf der 7. NanoMed-Konferenz in Berlin, um den aktuellen Stand biomedizinischer Anwendungen der Nanotechnologie zu diskutieren. Schwerpunktthema der Veranstaltung ist die nanotechnologie-basierte Diagnose und Behandlung von Krebs.
As a first step in the collaboration efforts, NTN will host a free live online webinar featuring an expert panel convened to discuss the latest investment and collaboration opportunities in Switzerland.
Am 16. Juni spricht der Empa-Nanotoxikologe Harald Krug am Technoseum in Mannheim im Rahmen einer grossen Nano-Ausstellung ueber Vor- und Nachteile der Nanotechnologie und erklaert, worin die Chancen bestehen und wo Vorsicht angesagt ist.
Scientists have leaped over a major hurdle in efforts to begin commercial production of graphene - a form of carbon that could rival silicon in its potential for revolutionizing electronics devices ranging from supercomputers to cell phones.
Scientists are reporting the first evidence that a plastic antibody - an artificial version of the proteins produced by the body's immune system to recognize and fight infections and foreign substances - works in the bloodstream of a living animal.
