Cost-effective and scalable preparation of two-dimensional (2D) molybdenum disulfide (MoS2) has been the bottleneck that limits their applications. This paper reports a novel coupled ultrasonication-milling (CUM) process to exfoliate natural molybdenite powders to achieve few-layer MoS2 (FL-MoS2) nanosheets in the solvent of N-methyl-2-pyrrolidone (NMP) with polyvinylpyrrolidone (PVP) molecules...

of individual isolated MWNTs potentially conferred to the material made from them can be achieved or exploited. [ 2–6 ] Consequently , direct use of nanotubes [ 7–10 ] in their intended application as deagglomer-ated MWNTs for mechanical stiffening and strengthening, conductivity control , [ 11 ] particularly in transparent media for the replacement of indium tin oxide as a nearly depleted reso...

Nowadays, electrospray is becoming a favourable approach for preparing monodispersed nanoparticles. However, this approach is quite recent and requires further works to optimize control over physicochemical properties of its products. This study aimed to determine the possible effects of sonication as a pretreatment to reduce the size of azelaic acid-chitosan particle before using electrospray....

Commercial polymer electrolyte membrane fuel cells have relied on scares Platinum to catalyse the kinetically sluggish oxygen reduction reaction occurring at their anodes. Over last decade organic materials, frequently based graphitic structures been demonstrated as promising alternative electrocatalysts noble metals. Researchers typically utilize ultrasonic treatment part of synthesis procedur...
