چکیده
Nanoscale patterning of fullerene materials with peculiar intrinsic electronic and optical properties is crucial importance for their widespread applications. However, it remains a daunting challenge current methods that suffer from both complicated lithography procedures additives photopolymers or photochemicals detrimental to the pristine fullerene. Here, we developed contamination-free laser printing approach in situ nanoscale resolution high purity. The trapping force within tight focus provides lithography-free means form densely packed nanostructures two-order-of-magnitude enhanced fluorescence emission surface roughness 6 nm. In addition, versatile nano-patterns dots concentric rings can be realized by flexibly shaping higher-order Laguerre–Gaussian beams. These results open new route programmable high-quality optoelectronic devices complex nanostructures.

Convenient separation of high-purity C60 from crude fullerene extract by selective complexation with AlCl3.
A purification procedure for C60 from the fullerene extract has been developed using the differential complexation of C60 and C70 with AlCl3 (or its conjugate acid) in CS2 solution. In addition to pure C60 (>99.8%), the procedure also provides C70-enriched fullerene mixture.
متن کاملHigh Quality Bioreplication of Intricate Nanostructures from a Fragile Gecko Skin Surface with Bactericidal Properties
The external epithelial surfaces of plants and animals are frequently carpeted with small micro- and nanostructures, which broadens their adaptive capabilities in challenging physical habitats. Hairs and other shaped protuberances manage with excessive water, light contaminants, predators or parasites in innovative ways. We are interested in transferring these intricate architectures onto biome...
متن کاملHigh purity amphotericin B.
OBJECTIVES Amphotericin B (AmB) is a drug of choice for treatment of disseminated fungal infections, but its use is often associated with severe adverse effects. Our observation that generic formulations of AmB contain multiple polyene components led us to propose that removal of other polyenes would yield a high purity AmB (AmBHP) with an improved therapeutic index. METHODS To test that prem...
