Druckfarben werden schneller hart mit Nanopartikel Photoinitiatoren

Zinkoxid-Nanopartikel, deren Oberflaeche mit organischen Saeuren beschichtet wurde, sind rund eine Zehnerpotenz groesser als herkoemmliche Photoinitiatoren. Dadurch sind sie unbeweglicher und werden wesentlich besser in den gehaerteten Druckfarben festgehalten.

Is smell a quantum effect?

A discussion of the current condition for theories of signal transduction in olfaction. One theory based on Luca Turin's hypothesis from 1996, holds promise; that an odorant's quantized vibrational mode (a phonon) may facilitate electron tunnelling which constitutes the recognition event in the nose. The novel mechanism is explored and explained.

'Green' cars could be made from pineapples and bananas

Your next new car hopefully won't be a lemon. But it could be a pineapple or a banana. That's because scientists in Brazil have developed a more effective way to use fibers from these and other plants in a new generation of automotive plastics that are stronger, lighter, and more eco-friendly than plastics now in use.

Therapeutic nanoparticles targeted to radiation treated tumors

Radiation and chemotherapy are common partners in anticancer therapy for solid tumors, but too often, the combined side effects associated with each mode of therapy can limit how aggressively oncologists can treat their patients. Now, a team of investigators from Vanderbilt University and Washington University in St. Louis, has developed a nanoparticle that only targets irradiated tumors, offering the potential for reducing chemotherapy-associated toxicities and increasing the effectiveness of combination therapy.

Biodegradable biopolymer nanoparticles hold promise for twin attack on breast cancer

Using a biodegradable polymer produced by a slime mold, a team of investigators from Cedars-Sinai Medical Center has created a multifunctional nanoparticle that attacks a key pathway involved in breast cancer in two different ways. Tests using animals with human breast tumors showed that the new nanoparticle produced a 90% reduction in tumor growth.
