The mass production of flower-like CrI3 monolayer on mica is achieved by a confined vapor epitaxy method.

BACKGROUND The synthesis of anisotropic silver nanoparticles is a time-consuming process and involves the use of expensive toxic chemicals and specialized laboratory equipment. The presence of toxic chemicals in the prepared anisotropic silver nanostructures hindered their medical application. The authors have developed a fast and inexpensive method for the synthesis of three-dimensional hollow...

Dear Dr. Bedrossian: Recognizing colloid is an essential part of thyroid fine needle aspiration (FNA) interpretation as the quantity of colloid and the numbers follicular cell are very good indicators of the nature of the lesion. Here, we reported a unique colloid morphology observed in FNA specimen from a 47-year-old female patient with a history of breast cancer and long standing thyroid nodu...

Nanostructured surface possessing ultrahigh adhesion like "gecko foot" or "rose petal" can offer more opportunities for bionic application. We grow flower-like few-layer graphene on silicon nanocone arrays to form graphene nanoclusters, showing robust adhesion. Their contact angle (CA) is 164° with a hysteresis CA of 155° and adhesive force for a 5 μL water droplet is about 254 μN that is far l...

Hierarchical tungsten oxide assemblies such as spindle-like structures, flowers with sharp petals, nanowires and regular hexagonal structures are successfully synthesized via a solvothermal reduction method by simply adjusting the reaction conditions. On the basis of the experimental results, it is determined that the reaction time significantly influences the phase transition, microstructure a...
