Stable high-concentration suspensions (up to 0.95 mg mL(-1)) of non-oxidized few layer graphene (FLG), five or less sheets, with micrometre-long edges were obtained via direct exfoliation of natural graphite flakes in ionic liquids, such as 1-butyl-3-methyl-imidazolium bis(trifluoro-methane-sulfonyl)imide ([Bmim]-[Tf(2)N]), by tip ultrasonication.

Herein, anacardic acid was applied for the preparation of nanosized cellulose using three different 11 treatment conditions including ultrasonication, microwave irradiation, and reflux. Physico-chemical 12 characterization undertaken FTIR, TEM, SEM, XRD. SEM analyses 13 confirm with similar chemical but physical properties as 14 starting material. In addition, calculated degrees crystallinities...

Responsive materials that alter their color in response to environmental changes can be used as optical sensors. Chiral nematic liquid crystals are photonic selectively reflect specific wavelengths of light and have been made environmentally responsive. Herein, the use ultrasonication responsive cholesteric liquid-crystal network films form structurally colored flakes demonstrate when moved fro...
