Researchers of the University of Twente's MESA+ research institute have developed spiral ribbons made of molecules, that are able to convert light into complex macroscopic motion. Therefore, they managed to amplify molecular motion and translate it to the macroscopic world.
One factor that makes glioblastoma cancers so difficult to treat is that malignant cells from the tumors spread throughout the brain by following nerve fibers and blood vessels to invade new locations. Now, researchers have learned to hijack this migratory mechanism, turning it against the cancer by using a film of nanofibers thinner than human hair to lure tumor cells away.
Fullerene bisadducts are promising electron-accepting materials because of the increased open-circuit voltage of BHJSCs based on these compounds compared with those based on PCBM. That led researchers to synthetize C60 bisadducts connected with the strong absorber perylenediimide (PDI) in a cyclic fashion.
A novel battery electrode features silicon nanoparticles clustered like pomegranate seeds in a tough carbon rind. The Stanford/SLAC design could enable smaller, lighter rechargeable batteries for electric cars, cell phones and other devices.
A new breed of ultra thin super-material has the potential to cause a technological revolution. 'Artificial graphene' should lead to faster, smaller and lighter electronic and optical devices of all kinds, including higher performance photovoltaic cells, lasers or LED lighting.
The multifunctional 'smart' gold nanoshells could lead to more effective cancer treatments by overcoming a major limitation of modern chemotherapy techniques - the ability to target cancer cells specifically and leave healthy cells untouched.
The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: researchers have developed the first ever single-molecule LED. The device is formed from a single polythiophene wire placed between the tip of a scanning tunneling microscope and a gold surface. It emits light only when the current passes in a certain direction.
